AB  - Microbial fuel cells (MFCs) are a promising technology that has the potential to solve environmental problems while simultaneously generating electricity. Thanks to the direct use of energy from the substrate and its conversion into electricity, as well as the controlled production of activated sludge, the multiplicity of independent applications highly qualifies MFC for the use of wastewater treatment. Wastewater from various industries is an ideal source of organic substrate that can potentially be used in MFC systems. In this way besides degrading organic pollutants, generated energy can be obtained as added value and used for various purposes.

AB  - Due to the similar chemical properties of Ni2+ and Co2+, several dozens of adsorptive stripping voltammetric (AdSV) methods have been developed for their simultaneous determination. The question was would there be some benefits if a stripping method made for simultaneous determination of Ni2+ and Co2+ will be optimized for the determination of only one of them (Ni2+). It was found that the optimized method has for an order of magnitude lower LOQ (1.89×10−10 M), an order of magnitude lower influence of Co2+, and the applicability of one calibration line for four orders of magnitude of Ni2+ concentration. The influence of some common anions and cations has been examined. The developed method was successfully applied for nickel content determination in real samples. The suitability of the developed method for the determination of Co2+ from the same solution in the second run, upon optimizations of deposition potential and time, was also explored. The LOQ obtained for Co2+ (3.61×10−11 M) is almost two orders of magnitude lower than LOQ of the method for simultaneous determination of both cations and, its LOD and LOQ are among few lowest obtained by AdSV methods for Co2+ determination. The developed method for Ni2+ and Co2+ determination from the same solution in two successive runs has significantly better analytical performances than the starting method for their simultaneous determination in one run.

AB  - in this study, in situ polymerization procedure in solvent mixture was used for the preparation of thermosetting PU nanocomposites (PUNCs) with different content of soft segment (from 30 to 60 wt%), and with the addition of organomodified montmorillonite clay (Cloisite 30B®) as the nanofiller, in an amount of 0.5 wt.%. The PUNCs were based on poly(dimethylsiloxane) macrodiol (PDMS) that represents soft segment and 4,4′-diphenylmethane diisocyanate (MDI) and hyperbranched polyester (BH-30) which were selected as the hard segment. The PUNCs are marked.
so that the last two numbers in title indicate wt.% of soft segment in materials. Namely, the main 
objective of this study is to analyze the effect of the soft segment content on the morphology of the 
prepared PU nanocomposite films using atomic force microscopy (AFM), scanning electron 
microscopy (SEM), and small- and near wide-angle X-Ray scattering (SWAXS) analyses. SEM 
images of the fractured surfaces were obtained on JEOL JSM-6610LV. AFM analysis was carried 
out by atomic force microscope (Dimension Icon, Bruker, USA). SWAXS measurements of the 
PUNCs were performed using SAXS instrument (originally Molecular Metrology, USA, recently 
considerably upgraded by SAXSLAB, now Xenocs).

AB  - Polyurethane (PU) nanocomposites are highly utilized in biomedical devices/implants due to their excellent mechanical properties, good biocompatibility, and low cytotoxicity. These PU nanocomposites with silver nanoparticles are well known potent antimicrobial agents. Biocompatible magnetic nanoparticles such as ferrites has also gained attention especially in various fields of drug delivery, biosensing and magnetic resonance imaging which requires highly specific magnetic nanoparticle (MNP) properties such as uniform size distribution, less agglomeration and stability in the biological medium. Among MNP, copper and zinc ferrites have been broadly applicable in biomedical, optoelectronic, catalysis and drug delivery. With a view to design PU/ferrites nanocomposites and to explore their antimicrobial potential, the present preliminary study reports the preparation of PU nanocomposites with copper ferrite and zinc ferrite (1 wt.%) and with the same composition. The nanocomposites were characterized using water absorption and swelling measurements. The antimicrobial activity of these composites was investigated against four bacterial strains: Staphylococcus aureus, Enterococcus faecium, Pseudomonas aeruginosa, and Klebsiella pneumoniae, and one Candida strain, C. albicans and compared with those of PU nanocomposites with silver ferrite nanoparticles. PU nanocomposites based on zinc and copper ferrites did not show antimicrobial activity, on the contrary they supported microbial attachment and growth. However, PU nanocomposites with silver ferrite did not show significant antibacterial activity but show antifungal activity and it is related with hydrophilicity of the prepared materials.

AB  - The problem of wastewater has long been ubiquitous and has great consequences for the environment and its
inhabitants. Microbial fuel cells (MFCs) have enormous potential for the treatment of wastewaters polluted with
azo dyes. The amount of energy that can be produced from a single-chamber MFC is sufficient to perform
decolorization and degradation of such dyes, which are widely used in the textile industry. This study on the azo
dye, reactive black 5 (RB5), provides an alternative method through three parallel-connected MFCs to obtain
electricity that directly serves for the dye’s electrochemical degradation. We examined degradation followed by
decolorization of RB5 using Fe and Pt electrodes, together with H2O2, to achieve the electro-Fenton process. The
amount of voltage produced (295 mV), the current density (276 mA m− 3
) and the power density (50 mW m− 3
)
were sufficient to degrade 25 mg L-1 RB5 dye with 0.5 mM H2O2 in just 2 h. The dye degradation mechanism was
investigated using UV–VIS, FT-IR and HPLC-MS/MS. The ecotoxicity of the degradation products was assessed
using a bacterial model, Aliivibrio fischeri. These tests showed that there was successful degradation of the dye to
products whose toxicity is less than that of RB5.

AB  - The novel polyurethane composite films were prepared using in situ polymerization method in thepresence of silver ferrite nanoparticles (1 wt.%). Preparation, structure, and thermal characterizationof polyurethane/silver ferrite nanocomposites (PUFNCs) were investigated. The study of the effectof soft segment content (from 30 to 60 wt.%) on the structure and thermal properties was performedusing FTIR, DSC, TGA and TEM analyses. The higher thermal stability was detected for PUFNCswith higher soft segment content. The glass transition of the hard segment (TgHS) of PUFNCsincreased with decreasing soft segment content due to higher crosslinking density.

AB  - Ibuprofen (IBP) zbog svoje giroke primene, velike konzumacije, relativno brzog metabolizma i eliminacije iz organizma, predstavlja potencionalni rizik po 2ivotnu sredinu. Hlor - dioksid, kao jako oksidaciono sredstvo, pokazao se kao dobar reagens za uklanjanje odredenih grupa pesticida iz hrane i vode, kao i za degradaciju odredenih lekova. Cilj ovog rada bio je da se ispita pod kojim uslovima i u kojoj meri hlor - dioksid mote da ukloni IBP u vodi. Ispitivana je degradacija IBP razlibitih koncentracija (10, 20, 35 i 60 mg/L) sa razli6itim koncentracijama hlor - dioksida (5, 10 i 15 mg/L) na pH vrednostima 3,00, 7,00 i 10,00 i pri razliditim rekcionim vremenima (0,5 h, 1 h, 2 h, 3 h, 6 h, 24 h). Rezultati HPLC - DAD analize su pokazali da je IBP mogude efikasno ukloniti iz vode. Najveda efikasnost degradacije od 99% postignuta je kada je koncentracija IBP u vodi bila 10 mg/L, a rastvor je bio tretiran sa 15 mg/L hlor - dioksida na pH 10,00 posle 24 h tretiranja hlor - dioksidom.
AB  - Due to ibuprofen (IBP) wide application, high consumption, relatively fast metabolism and elimination from the organism, it represents a potential risk for our environment. Chlorine dioxide, as a strong oxidizing agent, has been shown to be a good reagent for removing certain groups of pesticides from food and water, as well as for degradation of certain drugs. The aim of this study was to find optimal conditions for IBP removal from water using chlorine dioxide. Degradation of IBP of different concentrations (10, 20, 35 and 60 mg/L) with different concentrations of chlorine dioxide (5, 10 and 15 mg/L) at pH values of 3.00, 7.00 and 10.00 and at different reaction times (0.5 h, 1 h, 2 h, 3 h, 6 h, 24 h), was investigated. The results of HPLC - DAD analysis showed that IBP can be effectively removed from water. The highest degradation efficiency of 99% was achieved when the concentration of IBP in water was 10 mg/L, and the solution was treated with 15 mg/L of chlorine dioxide at pH 10.00 after 24 h of chlorine dioxide treatment.

AB  - Novel polyurethane nanocomposite (PUN) materials containing different surface-functionalized mesoporous silica nanoparticles (MSNs) were prepared by in situ polymerization methodology. Polyurethane network was formed from poly(dimethylsiloxane)-based macrodiol (PDMS), 4,4′-methylenediphenyldiisocyanate (MDI), and hyperbranched polyester of the second pseudo-generation (BH-20; used as crosslinking agent). PU and PU/MSN nanocomposites contained equal ratios of soft PDMS and hard MDI-BH-20 segments. Non-functionalized and surface-functionalized (with 3-(trihydroxysilyl)propyl methylphosphonate (FOMSN) and 2-[methoxy(polyethyleneoxy)6−9propyl]trimethoxysilane (PEGMSN)) MSNs were used as the nanofillers at a concentration of 1 wt%. Prepared materials were characterized by Fourier transform infrared (FTIR) spectroscopy, atomic force microscopy (AFM), scanning electron microscopy (SEM), thermogravimetric analysis (TGA), differential scanning calorimetry (DSC), dynamic mechanical thermal analyses (DMTA), nanoindentation, equilibrium swelling and water absorption measurements. Characteristics of the prepared PUNs when in contact with a biological environment were assessed through testing their biocompatibility, protein adsorption and adhesion of endothelial cells. The favourable influence of MSNs on the physico-chemical and biological characteristics of these novel PUN materials was identified, which evidences their vast applicability potential as coatings for medical devices and implants.

AB  - The main biologically active components of plants belonging to the genus Allium, responsible for their biological activities, including anti-inflammatory, antioxidant and immunomodulatory, are organosulfur compounds. The aim of this study was to synthetize the mixture of dipropyl polysul-fides (DPPS) and to test their biological activity in acute hepatitis. C57BL/6 mice were administered orally with DPPS 6 h before intravenous injection of Concanavalin A (ConA). Liver inflammation, necrosis and hepatocytes apoptosis were determined by histological analyses. Cytokines in liver tissue were determined by ELISA, expression of adhesive molecules and enzymes by RT PCR, while liver mononuclear cells were analyzed by flow cytometry. DPPS pretreatment significantly attenuated liver inflammation and injury, as evidenced by biochemical and histopathological observations. In DPPS-pretreated mice, messenger RNA levels of adhesion molecules and NADPH oxidase complex were significantly reduced, while the expression of SOD enzymes was enhanced. DPPS pretreatment decreased protein level of inflammatory cytokines and increased percentage of T regulatory cells in the livers of ConA mice. DPPS showed hepatoprotective effects in ConA-induced hepatitis, charac-terized by attenuation of inflammation and affection of Th17/Treg balance in favor of T regulatory cells and implicating potential therapeutic usage of DPPS mixture in inflammatory liver diseases.

AB  - Effectiveness, mineralization and toxicity of four organophosphorus pesticides (OPPs) azamethiphos (AZA), dimethoate (DM), fenitrothion (FEN) and malathion (MAL) in water with chlorine dioxide (ClO2) as degradation agent were investigated. Analyses included toxicity tests of parent pesticides and their degradation products (DPs), using Daphnia magna test organisms, and total organic carbon (TOC) analysis. Toxicity tests showed that all four pesticide DPs were less toxic than parent pesticides, but DM had higher toxic DPs compared to parent AZA, FEN and MAL. All DPs were classified as category III (on a scale from I to V) of toxicity as acutely toxic. TOC analysis showed that AZA has lowest (only 18%) and MAL has highest mineralization (56%). Considering the obtained results, it could be concluded that ClO2 efficiently degrades AZA, DM, FEN and MAL and represents good solution for a safer environment.

AB  - Chlorine dioxide has been reported as very
efficiently removing pesticides and other organic compounds
from water matrixes. Due to pesticide toxicity
and potential toxicity of their degradation products, it is
important to monitor these compounds as environmental
pollutants in ground and surface waters. Evaluating
the effects of chlorine dioxide treatment is necessary,
and toxicity studies are used to ascertain the severity of
effects of intermediates due to incomplete degradation
of the parent compounds. In this paper, for the first time,
chlorine dioxide is applied and evaluated for the removal
of chloroacetamide herbicides (pethoxamid and
metazachlor) from waters (deionized water and Sava
River water). The degradation degree of herbicides
was measured by high-performance liquid chromatography,
the main degradation products were identified
using gas chromatography with a triple quadrupole mass
detector, and the degree of mineralization was
monitored by total organic carbon analysis. Four and
two degradation products were identified after
pethoxamid and metazachlor degradation, respectively.
Total organic carbon analysis showed mineralization
occurred, but it was incomplete. The mineralization
and the characteristics of the degradation products obtained
were tested using Daphnia magna and showed
lower toxicity than the parent herbicides. The advantage
of the applied treatment was a very high degradation
percentage for pethoxamid removal from deionized water
and Sava River water (100% and 97%, respectively),
with higher mineralization efficiency (65%) than
metazachlor. Slightly lower degradation efficiency in
the Sava River water was due to chlorine dioxide oxidizing
the herbicides and dissolved organic matter
simultaneously

AB  - The aim of this study was to investigate, analyze,
and compare applied techniques suitable for achieving
efficient removal of organophosphorus pesticides (OPPs)
(malathion and fenitrothion) from aqueous solutions and
analyze the degradation products and processes. Pesticide
degradation efficiency (%) was monitored by highperformance
liquid chromatography (HPLC) equipped
with a photodiode array detector (DAD), while mineralization
degree was determined by total organic carbon analysis
(TOC). Daphnia magna was used for screening the environmental
safety aspects of the degradation methods, i.e.,
for assessing the toxicity of solutions obtained after degradation.
Additionally, a surface river water was utilized to
examine the likely influence of organic matter on the
pesticides’ degradation. Pesticide degradation products
were identified using gas chromatography with a triple
quadrupole mass detector (GC-MS/MS) as well as
ultrahigh-performance liquid chromatography coupled with
a linear ion trap, Orbitrap mass spectrometer (UHPLCLTQ
Orbitrap MS), and a simple pesticide degradation
mechanism is proposed. Removal of pesticides from water
using chlorine dioxide was successful, resulting in high
degradation efficiency (98% for malathion and 81% for
fenitrothion). Partial mineralization was achieved, and
Daphnia magna mortality decreased in the waters containing
degradation products (compared with the parent pesticides),
indicating that the solutions formed were less toxic
than the parent pesticides. Lower degradation rates (80%
formalathion and 72% for fenitrothion) in Sava Riverwater
were measured, indicating the influence of the organic
matter contained in this naturally occurring surface water.
The results prove that chlorine dioxide could be used as an
agent for successful removal of these OPPs from water.

AB  - Bentazone degradation efficiency and mineralization in water solutions using chlorine dioxide
treatment were evaluated. Double distilled water and a river water sample spiked with bentazone
were studied and compared after chlorine dioxide treatment. Degradation efficiency was determined
using high-performance liquid chromatography (HPLC). Daphnia magna toxicity testing and
total organic carbon (TOC) analysis were used to ascertain the toxicity of the degraded solutions
and mineralization degree. Bentazone degradation products were identified using gas chromatography
with a triple quadrupole mass detector (GC-MS-MS). A simple mechanistic scheme for oxidative
degradation of bentazone was proposed based on the degradation products that were
identified. Decrease in D. magna mortality, high degradation efficiency and partial bentazone mineralization
were achieved by waters containing bentazone degradation products, which indicate
the formation of less toxic compounds than the parent bentazone and effective removal of bentazone
from the waters. Bentazone degraded into four main degradation products. Humic acid from
Sava River water influenced bentazone degradation, resulting in a lower degradation efficiency in
this matrix (about 10% lower than in distilled water). Chlorine dioxide treatment of water to
degrade bentazone is efficient and offers a novel approach in the development of new technology
for removal of this herbicide from contaminated water.

AB  - Chlorine dioxide (ClO2) degradation of the organophosphorus pesticides azamethiphos (AZA) and dimethoate (DM) (10
mg/L) in deionized water and in Sava River water was investigated for the first time. Pesticide degradation was studied
in terms of ClO2 level (5 and 10 mg/L), degradation duration (0.5, 1, 2, 3, 6, and 24 h), pH (3.00, 7.00, and 9.00), and
under light/dark conditions in deionized water. Degradation was monitored using high-performance liquid chromatography.
Gas chromatography coupled with triple quadrupole mass detector was used to identify degradation products of
pesticides. Total organic carbon was measured to determine the extent of mineralization after pesticide degradation. Real
river water was used under recommended conditions to study the influence of organic matter on pesticide degradation.
High degradation efficiency (88–100% for AZA and 85–98% for DM) was achieved in deionized water under various
conditions, proving the flexibility of ClO2 degradation for the examined organophosphorus pesticides. In Sava River
water, however, extended treatment duration achieved lower degradation efficiency, so ClO2 oxidized both the pesticides
and dissolved organic matter in parallel. After degradation, AZA produced four identified products (6-
chlorooxazolo[4,5-b]pyridin-2(3H)-one; O,O,S-trimethyl phosphorothioate; 6-chloro-3-(hydroxymethyl)oxazolo[4,5-
b]pyridin-2(3H)-one; O,O-dimethyl S-hydrogen phosphorothioate) and DM produced three (O,O-dimethyl
S-(2-(methylamino)-2-oxoethyl) phosphorothioate; e.g., omethoate; S-(2-(methylamino)-2-oxoethyl) O,O-dihydrogen
phosphorothioate; O,O,S-trimethyl phosphorodithioate). Simple pesticide degradation mechanisms were deduced.
Daphnia magna toxicity tests showed degradation products were less toxic than parent compounds. These results
contribute to our understanding of the multiple influences that organophosphorus pesticides and their degradation
products have on environmental ecosystems and to improving pesticide removal processes from water.

Rezultati su pokazali da pH ima zna6ajan uticaj na stepen degradacije malationa. Ispitivani insekticid pokazuje dobar stepen degradacije. Vrednost stepena degradacije pri optimalnim uslovima za malation je 97,78 % primenom 5 mg/L hlor-dioksida na pH 7,00 posle 24 h tretmana. Analizom masenih spektara malationa utvrdeno je da su dobijeni degradacioni proizvodi: dietil 2-hidroksisukcinat, dietil fumarat, dimetil hidrogen fosfat, dietil 2-((dime-toksifosforil)tio)sukcinat.
AB  - In this paper, the degradation of organophosphorus insecticide (malathion) with chlorine dioxide was investigated. Degradation was studied in deionized water. Optimization of degradation conditions was examined under light condition, with different doses of chlorine dioxide, after different degradation times and at different pH values. This is the first study where degradation of malathion was done using chlorine dioxide as a degradation agent. The percentage of degradation was determined by HPLC-DAD, while the degradation products were isolated and identified by GC-MS. The results showed that pH has a significant influence on the degree of degradation. The value of degradation degree determined under the optimal conditions for malathion was 97.78 % using 5 mg/L chlorine dioxide at pH 7.00 after 24 h of treatment. By analyzing mass spectra of malathion, it was found that the resulting degradation products were diethyl 2-hydroxysuccinate, diethyl fumarate, dimethyl hydrogen phosphate and diethyl 2-(dimethoxyphosphoryl)thio)succinate.

AB  - In the present study, polyurethane/ferrite composites (PU-NFs) were prepared using silver ferrite, copper ferrite and zinc ferrite (1 wt.%) by in situ two-step polymerization in solution. PU-NFs based on poly(dimethylsiloxane) as soft segment and hyperbranched polyester of the second pseudo generation/4,4'-methylenediphenyl diisocyanate as the hard segment were prepared with constant soft segment content (60 wt.%). The prepared PU-NFs and PU network (sample without nanoferrites) were characterized by FTIR, DSC and TG analyses. The glass transition of the hard segment (TgHS) of PU-NFs was similar to TgHS value of the unfilled PU network. The results showed that PU-NFs had better thermal stability than pure PU network.
