AB  - The discharge of industrial textile waters into water bodies leads to the accumulation of pollutants which are a serious threat to humans and the environment. The development of an efficient adsorbent for the removal of toxic organic dyes from water is of crucial importance. For that reason, this work aimed to elaborate on the potential application of a biosorbent obtained from waste Humulus lupulus stems (Hlup-BA) for the elimination of malachite green, methylene blue, and crystal violet from aqueous solution in batch and fixed-bed column systems. The Hlup-BA was characterized using chemical composition analysis, by determination of particle size distribution, the point of zero charge (pHpzc), SEM, BET, EDS, XRD, and FTIR. Comprehensive analysis of Hlup-BA adsorption efficiency in a batch study showed that at the optimal conditions (e.g. contact time, 120 min; biosorbent dose, 2 g/L; dye concentration, 100 g/L; pH, 8 and temperature, 298 K), even 98.4 %, 98.8 %, and 98.5 % of MG, MB, and CV were removed, respectively. The results showed that the biosorption process followed pseudo-second-order kinetics. The equilibrium data were modeled using Langmuir, Freundlich, Sips, and Dubinnin-Radushkevich biosorption isotherms. High values of Hlup-BA biosorption capacities obtained from Langmuir isotherm were 398.9 mg g−1, 209.8 mg g−1, and 133.2 mg g−1 for MG, MB, and CV, thus proving Hlup-BA as an excellent biosorbent for removal of the tested dyes. The thermodynamic study indicated that the biosorption of these three dyes on Hlup-BA from aqueous solution is an endothermic, spontaneous, and thermodynamically stable process. The proposed mechanism of the biosorption process covers π-π interactions, electrostatic interactions, and hydrogen bonding. Furthermore, the data obtained by modeling in the fixed-bed column were also successfully correlated with the Thomas, Bohart-Adams, and Yoon–Nelson models. The very good fit of the results obtained in this way will greatly contribute to optimizing the pilot-scale operations for future wastewater treatment. Consequently, Hlup-BA can be an effective, cheap, and environmentally friendly biosorbent to eliminate methylene blue, malachite green, and crystal violet dyes from the aqueous solution in batch and column systems.

bazi platine koji pokazuju dobru efikasnost za reakciju oksidacije metanola.

pomoć mikrotalasnog zagrevanja i deponovane na ugljeničnu podlogu Vulcan

korišćenjem ciklične voltametrije i hronoamperometrijske tehnike.
Fizičkohemijska svojstva dobijenih katalizatora su okarakterisana
transmisionom elektronskom mikroskopijom (TEM), termogravimetrijskom
analizom (TGA) i energetsko disperzivnom spektroskopijom (EDS). Prema
TEM analizi svi katalizatori imaju male čestice prilično slične veličine između 1

Dodavanje Zn i Sn u Pt katalizator značajno poboljšava aktivnost oksidacije
metanola u poređenju sa Pt/C referentnim katalizatorom. Testovi stabilnosti

nanoparticles were produced using the microwave assisted polyol method and

electrochemical behaviour of synthesized catalysts was investigated utilizing
the cyclic voltammetry and chronoamperometric technique. To determine the catalyst's physicochemical characteristics, transmission electron microscopy
analysis (TEM), energy dispersive spectroscopy (EDS) and thermogravimetric
analysis (TGA) were used. According to TEM analysis all catalysts have small
particles of rather similar size between 1 and 3 nm. The obtained results
confirmed the successful synthesis of Pt-based catalyst. Addition of Zn and Sn
to Pt significantly improves methanol oxidation activity in comparison to Pt/C
benchmark catalyst. Stability tests also prove the lower poisoning and indicate
better stability and higher tolerance to CO-like intermediaries. The observed
high catalytic activity and good stability in the methanol oxidation reaction of

AB  - Due to their high electrocatalytic activity, Pt-based materials are widely investigated as electrocatalysts for the electro-oxidation of small organic molecules for fuel cells technology applications, contributing to the potential reduction of fossil fuel use in the near future. In addition to methanol, formic acid has also gained increasing attention as a potential fuel for direct fuel cells due to lower toxicity, non-flammability and a lower storage cost. The electro-oxidation of formic acid on Pt-based thin films is taking place predominantly via indirect pathway, through the dehydrogenation reaction of formic acid, with the formation of CO as a poisoning species. The activity of electrocatalysts is dependent both on surface structure and surface orientation in terms of the arrangement of the atoms at the surface. Controlled heat treatment led to the rearrangement of surface atoms thus enhancing the catalytic properties. In order to investigate changes in morphology before and after thermal annealing, Pt/CrNi catalysts were characterized using an atomic force microscope (AFM). The performance of all catalysts was tested in formic acid electro-oxidation reaction. The synergistic effect of individual metallic components, in the designed catalyst, resulted in high activity and exceptional stability. The approach demonstrated in this work may promote the development of new generation of high-performance catalysts for use in direct formic acid fuel cells (DFAFCs).

In order to investigate changes in morphology before and after thermal annealing, Pt/CrNi catalysts were characterized using an atomic force microscope (AFM). The performance of all catalysts was tested in formic acid electro-oxidation reaction. The synergistic effect of individual metallic components, in the designed catalyst, resulted in high activity and exceptional stability. The approach demonstrated in this work may promote the development of new generation of high-performance catalysts for use in direct formic acid fuel cells (DFAFCs).",

AB  - Procesi nukleacije i rasta dendrita kalaja iz alkalnog hidroksidnog elektrolita su istraženi hronoamperometrijom i skenirajućom elektronskom mikroskopskom (SEM) analizom taloga potenciostatski elektrohemijski istaloženih na selektivnim katodnim potencijalima.

Bez obzira na primenjeni katodni potencijal, dobijene bezdimenzionalne zavisnosti su bile niže od teorijskih predviđanja za progresivni tip nukleacije. Sa druge strane, morfologija dendrita kalaja je snažno zavisila od primenjenog katodnog potencijala, te igličasti ili dendriti nalik paprati su bili formirani potenciostatskim režimom elektrohemijskog taloženja. Na osnovu morfološke analize Sn dendrita elektrohemijski istaloženih različitim količinama elektriciteta, zaključeno je da nukleacija Sn iz ispitivanog elektrolita ipak sledi progresivni tip, i da se odstupanje od teorijskih predviđanja za ovaj tip može pripisati upotrebi kompleksnog elektrolita za elektrohemijsko taloženje kalaja.
AB  - The processes of nucleation and growth of tin dendrites from alkaline hydroxide electrolyte have been investigated by chronoamperometry and by the scanning electron microscopic (SEM) analysis of the deposits potentiostatically electrodeposited at the selected cathodic potentials. The Scharifker and Hills (SH) model based on three dimensional nucleation with diffusion controlled growth was used for a determination of a nucleation type. Irrespective of the applied cathodic potential, the obtained dimensionless dependencies were lower than the theoretical predictions for the progressive type of nucleation. On the other hand, morphology of Sn dendrites strongly depended on the applied cathodic potential, and either the needle-like or the fern-like dendrites were formed by the potentiostatic regime of electrodeposition. On the basis of the morphological analysis of Sn dendrites electrodeposited with various amounts of the electricity, it is concluded that nucleation of Sn from the examined electrolyte still follows the progressive type, and that the deviation of the theoretical predictions for this type can be attributed to use of complex electrolyte for Sn electrodeposition.

AB  - У овом раду, отпадна биомаса Аrundo donax (АД) је коришћена за адсорпцију Ni2+ из водених раствора. Површина АД је карактерисана СЕМ и ФТИР методама анализе. Адсорпциони експерименти су изведени у шаржним условима, при почетној pH вредности раствора pHi = 7 и различитим почетним концентрацијама Ni2+. Процес адсорпције је боље описан Фројндлиховим него Лангмировим моделом, односно адсорпција је вишеслојна са хетерогеном расподелом активних центара на површини материјала. Кинетика адсорпције Ni2+ на АД јe боље описана моделом псеудо–другог реда него моделом псеудо–првог реда, што указује на успостављање хемијских интеракција између адсорбата и слободних места на површини адсорбената. Добијени резултати су указали да АД има потенцијал за пречишћавање вода загађених никлом.
AB  - In this paper, Arundo donax (AD) waste biomass was used for the adsorption of Ni2+ from aqueous solutions. The AD surface was characterized by SEM and FT-IR analysis. Adsorption experiments were carried out in the batch adsorption system, at an initial pH value of pHi = 7 and different initial Ni2+ concentrations. The adsorption process was better described by Freundlich’s than by Langmuir’s model, i.e. adsorption is multilayered with a heterogeneous distribution of active sites on the material surface. The kinetic study of Ni2+ adsorption showed that pseudo–second order was the model that better described the experimental adsorption data compared to pseudo first order model, indicating the formation of chemical interactions between adsorbate and free sites on the adsorbent surface. The obtained results indicated that AD has the potential for the remediation of nickel-polluted waters.

AB  - One of the most popular alternative sources of energy are direct methanol fuel cells (DMFCs) with platinum-based catalysts due to their non-toxicity, reduced emissions of hazardous pollutants and high energy density. However, significant challenges of the scientific community related to Pt catalysts are the high cost, depletable resources and formation of poisoning species i.e. CO, during the methanol oxidation reaction. To reduce the amount of expensive Pt and susceptibility of Pt to poisoning species and simultaneously improve its catalytic performance, recent studies are focusing on the synthesis of Pt alloys in which a certain amount of platinum is replaced with less expensive metals such as Ru, Sn, Ni, Cu, Rh and Co. The usage of carbon (Vulcan XC-72R) for catalyst support enables high dispersion of metal, high surface area and good electrical conductivity improving overall performances of DMFCs. In this work, PtZn/C and PtSnZn/C catalysts were synthesized by the microwave-assisted polyol method. The structure and morphology of the catalysts were characterized by transmission electron microscopy (TEM), thermogravimetric (TG) and X-ray diffraction (XRD) analysis. The activity and stability of synthesized catalysts for methanol oxidation in 0.5 M sulfuric acid were investigated. It was demonstrated that the activity of the platinum catalysts was improved thanks to the synergistic effects caused by the addition of different metals, such are bifunctional and electronic effects.

AB  - In order to achieve widespread application of fuel cell technology, the
development of an efficient and economical catalyst is a crucial step. Reducing the
diameter of catalyst particles, producing particles with a specific orientation surface,
and alloying noble metals with less expensive metals are possible approaches to
improve catalyst performance. This study will be focused on novel ways for creating
PtSnZn catalysts that are more effective for the anodic reactions in fuel cell such are
methanol, ethanol and formic acid oxidation reactions. PtZn and PtSnZn
nanoparticles were produced using the microwave assisted polyol method and were
supported on high surface area carbon Vulcan XC-72R material. The electrochemical
behavior of synthesized catalysts was investigated utilizing the cyclic voltammetry,
chronoamperometric technique, and electro-oxidation of adsorbed CO. To determine
the catalyst's physicochemical characteristics, X-ray diffraction (XRD), transmission
electron microscopy analysis (TEM), and thermogravimetric analysis (TGA) were
used. High catalytic activity of the PtSnZn/C catalysts was achieved thanks to the
benefits of microwave synthesis and carefully adjusted metal alloying.

AB  - The processes of nucleation and growth of tin dendrites from the alkaline hydroxide solution have been investigated. Nucleation of tin was examined by chronoamperometry at the cathodic potentials which belonged to various positions at the polarization curve. The morphology of potentiostatically electrodeposited tin dendrites with various amounts of the electricity was characterized by scanning electron microscopy (SEM) technique. Depending on the cathodic potential applied for Sn electrodeposition, the following forms of Sn dendrites were obtained: the needle-like, the spear-like and the fern-like dendrites of various degree of ramification. Combining Sharifker and Hills (SH) model for a determination of nucleation type and results of morphological analysis of Sn dendrites, it is concluded that nucleation of Sn from the alkaline hydroxide solution follows the progressive type of nucleation.

AB  - In this study, the formic acid electrooxidation reaction was studied on a
platinum thin film catalyst obtained by deposition on chromium support (Pt/Cr).
In an attempt to reduce the proneness of Pt to poisoning species i.e. CO and
improve the catalytic performance of Pt/Cr at low potentials in the formic oxidation
reaction, the as- prepared catalyst was modified using controlled thermal
treatment. The influence of thermal treatment on the electrode surface
morphology was monitored using an atomic force microscope (AFM). Thus
obtained catalyst was electrochemically characterized with cyclic voltammetry
and oxidation of CO monolayer, while the performance of the catalyst was tested
in a formic acid oxidation reaction. The improved activity on annealed Pt/Cr
system is a consequence of the surface reconstruction of Pt film with
predominant (111) orientation. Compared to other facets, the (111) facet
selectively favors direct HCOOH oxidation, avoiding Coad poisoning at low
potentials. Moreover, the Pt (111) facets offer improved stability of the catalyst
compared to the as-prepared polycrystalline film. Finally, the Cr substrate also
experiences improved stability after annealing, presumably due to the formation
of a protective oxide layer. Thus, with the successful choice of the supporting
material and annealing temperature, we were able to create a thin film catalyst
with improved activity, selectivity and stability, in contrast with commonly
observed activity-stability tradeoff in catalysis.

AB  - The electrocatalytic oxidation of small organic molecules, such as methanol,
ethanol and formic acid has been extensively studied due to their properties that make
them suitable for use in fuel cells. Particularly, the electrochemical oxidation of
formic acid has been comprehensively examined as the anodic reaction in direct
formic acid fuel cell. The main goal in the development of the catalysts for formic
acid oxidation (FAO) is to find the optimal balance between catalytic performance
(activity/stability) and the catalyst cost, i.e. quantity of the noble metal used.
In the work presented herein, we explored the synergistic effects of the
supporting material and annealing temperature on the performance of Pt thin film
catalysts for FAO in acidic media. Our results show that compared to the as-prepared
Pt films, the annealed (500 oC) films show exceptional activity for FAO reaction on
both Pt/Ni and Pt/Cr catalysts, with 5-fold and 15-fold improvement, respectively.
The 500 oC annealed Pt/Cr catalyst was found to be the most active, the most
selective and the most stable catalyst in our study. A catalyst with the best marks for
all three characteristics is a very rare find in electrocatalysis in general.

PtZn catalyst materials with tunable content of Zn. Nanoparticles of PtZn
deposited on high surface area carbon Vulcan XC-72R material were
synthesized by microwave-assisted polyol method, giving control over the size
and dispersion of nanoparticles. Cyclic voltammetry and electrooxidation of
adsorbed CO were used to investigate the electrochemical behavior of
synthesized catalysts: PtZn/C (90:10); PtZn/C (85:15) and PtZn/C (75:25). It
was found that PtZn/C catalysts have high electrocatalytic performance in
methanol oxidation reactions. In comparison to the corresponding catalyst with
the different Zn loading, it was concluded that PtZn (90:10)/C catalyst had
better activity compared to PtZn/C (85:15) and PtZn/C (75:25) catalysts. The
observed high catalytic activity in the methanol oxidation reaction of
synthesized catalysts can be ascribed to the very efficient microwave synthesis
and well-balanced content of Zn as alloying metal.

AB  - Pollution caused by the usage of fossil fuels is a consequence of industrialization, urbanization, and technological development, having a huge impact on the environment and human health. Thus, one of the biggest challenges that currently confront not only the scientific community but also humanity is reducing the use of fossil fuels, as well as the production and consumption of energy using renewable energy sources. In the last decades, small organic molecules such as methanol, ethanol and formic acid have attracted attention due to their properties that make them convenient for use in fuel cells. Among other precious metals, Pt is the most investigated as a promising catalyst for the anodic electrooxidation reaction of small organic molecules. However, high price, scarceness and susceptibility to poisoning are some of the limiting factors for the commercial use of pure Pt. There are two ways to mitigate those problems: lower the content of a noble metal present or make the catalyst more active for the particular reaction. To address the first problem nanocatalyst, produced by the deposition of platinum onto high surface area supports were introduced. A far greater challenge is to modify the catalyst to make it not just more active, but more stable as well, for a particular reaction. It is now well known that bimetallic catalysts fulfill these requirements quite well, and currently, they are widely used in many catalytic and electrocatalytic processes. In this study, a thin Pt film was electrochemically deposited on nickel support (Pt/Ni) and afterward subjected to the controlled thermal treatment in an attempt to reduce the proneness of Pt to poisoning species (CO) and therefore improve its catalytic performance at low potentials in the formic oxidation reaction. All produced catalysts were electrochemically characterized using cyclic voltammetry and oxidation of CO monolayer, while the influence of thermal annealing on the morphology was monitored using an atomic force microscope (AFM). Finally, catalyst performance was tested in a formic acid electrooxidation reaction. The obtained results clearly show that the exceptional activity for formic acid electrooxidation, measured on annealed Pt/Ni is a direct consequence of the nature of the substrate which manifests itself after controlled heat treatment through surface reconstruction and bifunctional effect.

AB  - Polymer electrolyte membrane fuel cells (PEMFCs) are pure electrochemical energy converters that are key components of energy sources for vehicles and for stationary and portable energy suppliers. Searching for a good catalyst for the ethanol oxidation reaction is one of the most significant issues in material science. To increase the economic potential of fuel cell technology, catalyst must be extremely active, stable, and inexpensive. Due to its high catalytic activity, structural and chemical stability, and widespread use in commercial fuel cells, platinum is still the material of choice for making cathodes. Although there is extensive continuing research to reduce the Pt concentration while keeping the high catalytic activity, its high cost remains a barrier to a wider adoption of fuel cell technology.Therefore, the potential for cost reduction lies in the optimization of the catalyst, i.e. obtaining the maximum catalytic efficiency with the lowest possible content of noble metals. The focus of this research will be on novel synthesis techniques for PtSnZn catalysts with better efficiency and durability for the ethanol oxidation reaction. This research demonstrates the potential of studying new PtSnZn catalytic materials as catalysts for the oxidation of ethanol. This study used the microwave assisted polyol technique to create PtZn and PtSnZn nanoparticles supported on high surface area carbon Vulcan XC-72R material. By using cyclic voltammetry, electro-oxidation of adsorbed CO, and the chronoamperometric method, the electrochemical behavior of synthesized catalysts was examined. X-ray diffractometry, transmission electron microscopy analysis and thermogravimetric analysis were applied to obtain the physicochemical properties of the catalyst. The advantages of microwave synthesis and carefully balanced metal alloying in the PtSnZn/C catalysts led to a high catalytic activity of the synthesized catalyst in the ethanol oxidation reaction compared to the Pt/C catalyst.

AB  - Kaolinite/illite (KUb) and sepiolite (SEP) clays were used to study Cr(III) adsorption removal from aqueous solutions so that they could be utilized after saturation for ceramic manufacturing. SEP had a larger specific surface area and a higher PZC than KUb. The removal of Cr(III) was evaluated using a batch equilibration procedure at pHi = 4 and pHi = 6. Fast removal kinetics were observed for both clays. Maximum removal capacity was determined by changing the concentration of Cr(III) while keeping the concentration of clay constant and by altering the amount of clay while keeping the concentration of Cr(III) constant. In all situations, SEP had greater capacity than KUb, and capacity was greater for both clays at higher pHi. Not only did the pHi impact the removal capacity and efficiency, but so did the pH during adsorption and the initial concentration of Cr(III). Because of the higher PZC, the pHf for SEP was higher for the same pHi. The higher the pH and Cr(III) concentration, the higher the probability of Cr(OH)3 precipitation and the higher the removal capacity. Dried saturated clays were uniaxially pressed and sintered at 1000 °C for 2 h. The densities of the sintered materials were nearly identical to those of pure clay-based materials, but the compressive strengths were higher, which is significant for the use of saturated clays as raw materials in ceramic manufacturing. Leaching of Cr from SEP-based material was significantly higher than from KUb-based material probably due to the presence of CaCO3 in the SEP.

AB  - This work highlights the potential for the synthesis of new PtSnZn catalysts with enhanced efficiency and durability for methanol oxidation reaction (MOR) in low-temperature fuel cells. In this research, PtZn and PtSnZn nanoparticles deposited on high surface area Vulcan XC-72R Carbon support were created by a microwave-assisted polyol method. The electrochemical performances of synthesized catalysts were analyzed by cyclic voltammetry and by the electrooxidation of adsorbed CO and the chronoamperometric method. The physicochemical properties of obtained catalysts were characterized by transmission electron microscopy (TEM), thermogravimetric (TGA) analysis, energy dispersive spectroscopy (EDS) and by X-ray diffraction (XRD). The obtained findings showed the successful synthesis of platinum-based catalysts. It was established that PtSnZn/C and PtZn/C catalysts have high electrocatalytic performance in methanol oxidation reactions. Catalysts stability tests were obtained by chronoamperometry. Stability tests also confirmed decreased poisoning and indicated improved stability and better tolerance to CO-like intermediate species. According to activity and stability measurements, the PtSnZn/C catalyst possesses the best electrochemical properties for the methanol oxidation reaction. The observed great electrocatalytic activity in the methanol oxidation reaction of synthesized catalysts can be attributed to the beneficial effects of microwave synthesis and the well-balanced addition of alloying metals in PtSnZn/C catalysts.

AB  - Nickel pollution of aquatic ecosystems has been a serious environmental threat during the last few decades and is of great environmental importance. This concern stems from the fact that nickel is biodegradable, highly toxic, and can potentially cause numerous adverse effects on human health. In this work, the biosorption of nickel ions at different contact times was investigated using hop biomass waste. The high correlation coefficient value of 0.999 indicates that the adsorption kinetics follows a pseudo-second-order model. Hops showed high potential for Ni2+ removal from aqueous solutions with an efficiency ofup to 86%. The use of waste biomass of hops can be an efficient, economical and ecologically suitable option for the preservation of the environment.

AB  - It is known that surface structure is one of the critical issues affecting the activities of electrocatalysts. Heat treatment is an efficient approach to induce the rearrangement of surface atoms and thus to tailor their catalytic properties. The surface characteristics of electrochemically deposited Pt thin films at different substrates, as well as the effect of thermal annealing, were probed for electrooxidation of CO and methanol.
Our results show that heat treatment in the reductive atmosphere (95% Ar+5% H2) at 300 oC can substantially affect the degree of surface atom rearrangement and thus induce long-range order creating domains with large fractions of (111) and (100) sites without the use of an epitaxial template, translating into significant influence on their catalytic properties. Since the catalytic reactions take place at the surfaces, our work demonstrates an easy-to-implement way to control the atomic orientations in order to understand the relationship between structure and catalytic properties of catalyst for methanol oxidation and proposes a method to design advanced electrocatalysts.

AB  - Expanded vermiculite (EV) was modified by deposition of different spinel ferrite composites on the outer surface of EV 2:1 layers in order to improve its adsorptive properties. Modifications were made by deposition of: magnetite, manganese ferrite, cobalt ferrite and chromium oxide/hematite. The characterization of modified materials was performed by: scanning electron microscopy (SEM), Brunauer-Emmett-Teller (BET) methodology, X-ray diffraction (XRD), Fourier-transform infrared spectroscopy (FTIR), magnetization measurements, as well as determination of cation exchange capacity (CEC) and pH point of zero charge (pHPZC). Obtained samples were used as adsorbents for Pb2+, Ni2+and Cd2+ ions from an aqueous solution in a batch system. Results showed that adsorption capacity was strongly dependent on physical and chemical changes induced by specific chemical modification. Hydrothermally produced manganese and cobalt ferrites caused significant surface changes and altered the interlayer cation balance. Among the others, EV-Mn/Co-ferrite(s) samples possessed the highest adsorption capacity towards Ni2+ (33.06 mg g-1), along with an increase of the CEC. Freundlich's adsorption isotherm model provided the best fit of obtained experimental data, while kinetic studies showed that the adsorption rate follows the pseudo second-order model, implying heterogeneous adsorbents surface. Thermodynamic and kinetic parameters indicated that the mechanism of cations removal efficacy was dominantly followed by the ion exchange. This study confirmed that doped ferrites, produced by solvothermal method, improve surface properties of EV and increase adsorption potentials towards heavy metals.

AB  - In this study, the corrosion inhibitory activity of symmetrical bis(imino)pyridine (BIP-16) was tested by the Linear Polarization Resistance (LPR) and Electrochemical Impendence Spectroscopy (EIS) methods on zinc and iron. The investigation was carried out in a neutral and acidic medium of 0.5 M NaCI solution. The temperature-dependent (25-45 °C) inhibitory efficacy of BIP-16 on iron and zinc was tested in an acidic medium (pH 3). Under the same conditions, the time dependence of BIP-16 up to 72 h was examined . Moreover, a synergistic effect of BIP-16 with cerium acetate was also examined in time and temperature (25-45 °C) dependence on zinc (pH 7) and iron (pH 3) in 0.5 M NaCI solution at optimal concentrations. The inhibition efficiency of BIP-16 declined with time on both zinc and iron indicating physisorption. Also, kinetic and thermodynamic parameters of this process were calculated. To gain deeper insights into the inhibitory mechanism of tested compounds, DFT calculations were performed.

AB  - The importance of biofilms in caves, the diversity of microorganisms
in them, their mutual relationship and relationship with the substratum are among the advancing research topics in microbial biospeleology. This research is making contribution to the
knowledge about biofilms at cave entrances and phototrophic communities in them. In that
manner, biofilms from the entrance zone of the Petnica Cave were examined. Light microscopy showed that cyanobacteria were exclusively dominant phototrophs (34 taxa out of 39
total taxa recorded) with coccoid forms prevailing (28 taxa); simple trichal forms were present to a lesser extent, while heterocytous ones were completely absent. Genera Gloeocapsa,
Chroococcus,Gloeothece and Leptolyngbya were the most diverse. Four green algal genera
characteristic for aerophytic habitats (Apatococcus, Desmococcus, Haematococcus and
Trentepohlia) were also recorded, while Bacillariophyta were observed sporadically. Three
groups of sampling sites were distinguished based on recorded taxa, their richness and similarity, using non-metric multidimensional scaling (NMDS). Quantitative biofilm characteristics were also assessed – the content of chlorophyll a (Chl a) was determined, as well
as the contents of water, organic and inorganic matter. Chl a had a significant positive correlation with the content of organic matter (r=0.904, P=0.013).
AB  - Значај биофилмова у пећинама, разноврсност микроорганизама у њима, њихов међусобни однос, као и однос са супстратом, спадају у водеће теме истраживања у пољу микробијалне биоспелеологије. Ово истраживање доприноси општем познавању биофилмова на улазима пећина, као и познавању фототрофних заједница које се налазе у њиховом саставу. Имајући то у виду, испитивани су биофилмови са улазне зоне Петничке пећине. Светлосна микроскопија је показала да су цијанобактерије искључиво доминантни фототрофи 
(забележено је 34 од укупно 39 таксона), са изузетном доминацијом кокоидних форми (28 таксона); трихалне форме (хомоцитни представници) су у биофилму заступљене у мањој мери, док су хетероцитне потпуно одсутне. У родовима Gloeocapsa, Chroococcus, Gloeothece и Leptolyngbya документован је највећи број таксона. Четири рода зелених алги која су иначе карактеристична за аерофитска станишта (Apatococcus, Desmococcus, Haematococcus и Trentepohlia) су такође забележена, док су представници раздела Bacillariophyta нађени спорадично. Статистичка анализа NMDS је показала да су се према сличности, односно на основу таксона који су идентификовани, одвојиле три групе тачака узорковања. Kвантитативне карактеристике биофилма су такође процењене – одређен је садржај 
хлорофила а (Chl a), као и садржај воде, органске и неорганске материје. Значајнa 
позитивна корелација (r=0.904, P=0.013) уочена је између садржаја органске материје и Chl a.

knowledge about biofilms at cave entrances and phototrophic communities in them. In that
manner, biofilms from the entrance zone of the Petnica Cave were examined. Light microscopy showed that cyanobacteria were exclusively dominant phototrophs (34 taxa out of 39
total taxa recorded) with coccoid forms prevailing (28 taxa); simple trichal forms were present to a lesser extent, while heterocytous ones were completely absent. Genera Gloeocapsa,
Chroococcus,Gloeothece and Leptolyngbya were the most diverse. Four green algal genera
characteristic for aerophytic habitats (Apatococcus, Desmococcus, Haematococcus and
Trentepohlia) were also recorded, while Bacillariophyta were observed sporadically. Three
groups of sampling sites were distinguished based on recorded taxa, their richness and similarity, using non-metric multidimensional scaling (NMDS). Quantitative biofilm characteristics were also assessed – the content of chlorophyll a (Chl a) was determined, as well
as the contents of water, organic and inorganic matter. Chl a had a significant positive correlation with the content of organic matter (r=0.904, P=0.013)., Значај биофилмова у пећинама, разноврсност микроорганизама у њима, њихов међусобни однос, као и однос са супстратом, спадају у водеће теме истраживања у пољу микробијалне биоспелеологије. Ово истраживање доприноси општем познавању биофилмова на улазима пећина, као и познавању фототрофних заједница које се налазе у њиховом саставу. Имајући то у виду, испитивани су биофилмови са улазне зоне Петничке пећине. Светлосна микроскопија је показала да су цијанобактерије искључиво доминантни фототрофи 
(забележено је 34 од укупно 39 таксона), са изузетном доминацијом кокоидних форми (28 таксона); трихалне форме (хомоцитни представници) су у биофилму заступљене у мањој мери, док су хетероцитне потпуно одсутне. У родовима Gloeocapsa, Chroococcus, Gloeothece и Leptolyngbya документован је највећи број таксона. Четири рода зелених алги која су иначе карактеристична за аерофитска станишта (Apatococcus, Desmococcus, Haematococcus и Trentepohlia) су такође забележена, док су представници раздела Bacillariophyta нађени спорадично. Статистичка анализа NMDS је показала да су се према сличности, односно на основу таксона који су идентификовани, одвојиле три групе тачака узорковања. Kвантитативне карактеристике биофилма су такође процењене – одређен је садржај 
хлорофила а (Chl a), као и садржај воде, органске и неорганске материје. Значајнa 
позитивна корелација (r=0.904, P=0.013) уочена је између садржаја органске материје и Chl a.",

AB  - Aquatic pollution caused by pesticides as a consequence through run-off, leaching, and subsurface drainage, may pose a serious health hazard for living being and ecosystems due to
pesticides persistent nature and bio-magnification. Since most organic pesticides are nondegradable and carcinogenic, they represent a potent category of water contaminants. The aim
of the presented work was to develope functional biodegradable membranes which could be used
as an efficient adsorbent for the removal of pesticides (difenoconazole and thiophanate-methyl)
from aquatic solutions. The bio-renewable membranes (Cell-El and Cell-El-Ta) based on epoxyamino reactivity of the Cellulose fibres (Cell) modified with diethylenetriamine (Cell‒Deta), (3-
Glycidyloxypropyl)trimethoxysilane (Cell-Glymo), Lignin modified with epichlorohydrine (El)
and Tannic acid (Ta), as an additional crosslinker, were produced by optimized methods through
the application of novel approaches. The membrane preparation was conducted at the
appropriate molar ratio of functional groups designed to provide numbers of residual
functionalities effective for pesticide removal. The membranes were characterized by FourierTransform Infrared Spectroscopy (FTIR) and Scanning Electron Microscopy (SEM). FTIR
spectral analysis was used to identify the characteristic functional groups of produced
membranes and spectral pattern change as a result of the formation of coordination complexes
of pesticides with surface functionalities. Controlled modification of Cell fibre and subsequent
production of Cell-El and Cell-El-Ta membrane causes change fibres surface and material
morphology, and SEM analysis proved successful modification and membrane production with
formation a large number of fibres interconnections. The effects of contact time, temperature,
and initial concentration of pesticides on adsorption were studied in a batch system. The
Langmuir, Freundlich, Temkin, and Dubinin-Radushkevich (D-R) isotherm models were used to
evaluate the adsorption process, and to predict the adsorption capacity of the adsorbents. The
experimental results were best fitted with the Langmuir isotherm model. The calculated
capacities: 32.2, 69.3, 45.1 and 83.2 mg g-1 for difenoconazole and thiophanate-methyl using
Cell-El and Cell-El-Ta, respectively, were obtained from Langmuir model fitting at 25oC. The
thermodynamic parameters indicated spontaneous and low endothermic processes. The present
study demonstrates that prepared membranes could be an effective and low-cost adsorbent to
prevent contamination of water and consequently help minimize the environmental impact
caused by the pesticides.
