AB  - Pertussis (whooping cough) has been nearly eradicated during the 20th century, first of all due to an organized and comprehensive vaccination campaign that lasted for decades. Generations of doctors educated in Serbia (and other countries) rarely had an opportunity to see the clinical picture of pertussis. However, during 2023, the number of registered cases of pertussis in Serbia has increased several times. This is why the health authorities were forced to declare danger of an epidemic. During 2023, in Belgrade, around 1000 cases were registered. During the two months of 2024, 400 cases were registered. Some of them have ended with lethal outcome. This paper reports for the first time the biosynthesis reaction and thermodynamic properties of biosynthesis (enthalpy, entropy and Gibbs energy) of Bordetella pertussis, the cause of whooping cough. Moreover, a mechanistic model of multiplication of B. pertussis was developed. The mechanistic model was related to the pathogenesis of pertussis.

Naime, nekovalentna interakcija i formiranje OHad ‒ katjonskih klastera određuju interakciju alkoholne OH grupe sa OH grupom na površini Pd, i posledično određuju aktivnost Pd u ispitivanim reakcijama. Može se zaključiti da izbor katjona alkalnih metala reguliše elektrokatalitičku aktivnost i da se može smatrati jednim od bitnih parametara u elektrokatalizi.
AB  - Rationally designing of noble metal materials are of great interest for supporting their applications in the field of electrocatalysis. In this contribution, we demonstrated the galvanostatic preparation of Pd from surfactant free solution. Scanning electron microscopy analysis revealed Pd nanospheres of up to 300 nm. Comparative study of methanol and ethanol electrochemical oxidation reveals higher catalyst activity in LiOH solution in regard to NaOH solution due to the formation of OHad ‒ cation clusters. Namely non-covalent interaction and formation of OHad ‒ cation clusters govern the interaction of the alcohol OH group with the OH group on the Pd surface, and in turn determined its electrooxidation activity on Pd. It was pointed out that the choice of alkali metal cations regulate the electrocatalytic activity and can be considered as one of the tuning parameter in electrocatalysis.

AB  - Transition metal oxides (TMOs) have gathered increasing attention in material science due to their good electrical,
mechanical, optical properties and great chemical and thermal stability. Among them, ruthenium oxide (RuO2), with
its excellent catalytic performances has been the subject of numerous studies. It serves as a crucial material for
electrodes in (electro)catalysis, energy storage systems, and semiconductor devices. RuO2-based catalysts have
shown good potential in many important reactions such as the low-temperature dehydrogenation of small
molecules (NH3, HCl, methanol), and have been utilized in industrial electrolysis for chlorine-alkali production [1,2].
There are numerous techniques to synthesize RuO2 [1]. In response to the challenges associated with RuO2
synthesis, and to customize the particle size and shape of RuO2, an electrochemical deposition from a new class of
non-aqueous electrolytes, namely the deep eutectic solvents (DESs), can be a good alternative. So far, there have
been recorded some attempts to electrochemically deposit ruthenium/ruthenium oxides from DES [3,4].
This study focuses on the electrochemical deposition of ruthenium oxide onto palladium working electrode from
choline chloride (ChCl): urea (1:2 ratio) DES at 80 °C with 0.01M Ru(III) ions concentration. RuCl3 was added as a
source of Ru ions in the working electrolyte. To determine the potential range available for Ru electrodeposition in
DES, cyclic voltammetry (CV) on Pd working electrode in the electrolyte containing ChCl and urea was recorded.
The potential window of electrochemical stability was between -1.2 and +0.3V vs. Pt. The electrochemical behaviour
of Ru(III) in choline chloride-urea has been investigated at palladium using cyclic voltammetry (CV) and square wave
voltammetry (SWV). The CV results showed only cathodic peaks without corresponding anodic counterparts, and
SWV was used for further investigation in order to gain a better understanding of the Ru(III) electroreduction
process. The electrochemical impedance spectroscopy (EIS) results indicate diffusion-controlled RuO2 deposition.
Relatively small deposition overpotential (-1.0 V) applied in the electrodeposition experiments, resulted in
ruthenium oxide being electrodeposited. The morphology of the obtained deposits was characterized using
scanning electron microscopy (SEM) and energy dispersive spectroscopy (EDS). X-ray diffraction (XRD) analysis of
the produced particles provided conformation that the RuO2 was formed onto a palladium working substrate.

AB  - In the progressive energy transition process, rare earth elements (REE) became key components in crucial products
that play a central role in the development of renewable energy and low-carbon technologies. With China currently
producing more than 90 % of the world's REE output, many of the world's economies are facing REE supply risk [1].
To address this problem, many countries need to look for alternative resources of rare earths, e.g. recycling of these
elements from REE-containing end-of-life products. A new route for recovery of REE from NdFeB magnet scrap,
using a combination of pyrometallurgical treatment of spent NdFeB magnets, and a subsequent molten salt
electrolysis process, has been investigated in the authors’ laboratory [2]. The magnet recycling derived oxides
(MRDO), were produced from spent NdFeB magnets by oxidation in air and subsequent carbothermal reduction
under an 80 mbar Ar gas atmosphere. High-temperature molten salt electrolysis was introduced as an option that
enables the separation of rare earth elements from fluoride-based molten salts using produced MRDO [3]. One of
the challenges in this electrochemical approach for REE electrowinning is effective control of the anode effects to
make the electrolytic production of rare earths more environmentally friendly [3,4]. Minimizing the perfluorocarbon
compounds emission (PFC), in rare earth electrolysis, should be the primary goal, owing to their high global
warming potential [4,5].
In the present work, we investigated the off-gases emissions during the REE electrolysis from NdFeB magnet scrap
using in-situ FTIR-spectrometry, in order to understand the formation pathways of CO, CO2, and perfluorocarbon
gases (CF4 and C2F6) made at the anode. The electrolytic extraction of rare earths from fluoride-based molten salts
with different contents of MRDO present was performed using molybdenum (Mo) as a cathode, tungsten (W) as a
reference electrode, and a glassy carbon (GC) electrode as an anode. It was found that depending on the content
of the starting material, the dissolution of MRDO in their corresponding fluoride molten salts most probably induces
the formation of different oxyfluoride complexes and their subsequent reactions on the GC anode. The anode
reactions in the fluoride-based melts are, most likely, results of either oxide or fluoride formation by exchange with
the fluoride or oxide complexes present in the electrolyte. The produced oxygen subsequently reacts with carbon
to generate CO and CO2. With F− present, PFC compounds such as CF4 and C2F6 can also be formed from a GC anode.
The anode gas products are composed mainly of CO and CO2. The average CO2 concentration was approximately
450 ppm, while CO concentration was around 40 ppm. CF4 emissions in off-gas products were detected periodically,
except for some spikes, and even then, the concentration was below 4 ppm. C2F6 was not detected. The results
indicate that the electrodeposition of REE within the applied potential range occurs at the expense of their
corresponding oxides, provided by MRDO. To develop a more efficient RE recovery process, we opted for a low
deposition overpotential to suppress the emission of greenhouse gases and further enhance the control of their
emission in rare earth electrolysis.

AB  - Microplastics (MPs) interact with proteins, forming a complex called a protein corona. This corona
alters the biological identity and properties of MPs, enabling them to evade the immune system,
persist longer in circulation, and disrupt cellular and molecular processes. Biofilm formation on
MPs occurs in several steps, starting with initial binding of molecules to form a hard corona,
followed by the formation of a soft corona. β-Lactoglobulin (BLG), a major whey protein in bovine
milk, is highly valued as a food ingredient but poses significant health risks to milk-allergic
individuals. This study aimed to understand BLG's interactions with selected MPs (polyethylene
terephthalate, PET, <80μm; polypropylene, PP, 63-180μm). BLG, isolated from
unpasteurized/pasteurized milk, was incubated with PP and PET in simulated physiological fluids.
The resulting coronas were analyzed using reduced SDS-PAGE electrophoresis and densitometry.
BLG exhibited low binding to both MPs, with pasteurized BLG showing the lowest binding to PP
(less than 1% of control in its soft corona). There were differences in the protein content of hard
coronas between pasteurized and unpasteurized BLG, with a slightly higher percentage of bound
proteins in the hard corona of unpasteurized BLG. Additionally, the protein profile of hard coronas
differed between PET and PP incubated with pasteurized BLG compared to those with
unpasteurized BLG. These findings suggest that the presence of MPs may affect the bioavailability
and allergenic properties of both pasteurized and unpasteurized BLG.
AB  - Interakcija mikroplastike (MP) s proteinima stvara kompleks poznat kao proteinska korona. U okviru korone, MP dobija nove biološke osobine, uključujući izbegavanje imunog sistema, dugotrajnije zadržavanje u cirkulaciji i ometanje ćelijskih procesa.

abstract = "Microplastics (MPs) interact with proteins, forming a complex called a protein corona. This corona
alters the biological identity and properties of MPs, enabling them to evade the immune system,
persist longer in circulation, and disrupt cellular and molecular processes. Biofilm formation on
MPs occurs in several steps, starting with initial binding of molecules to form a hard corona,
followed by the formation of a soft corona. β-Lactoglobulin (BLG), a major whey protein in bovine
milk, is highly valued as a food ingredient but poses significant health risks to milk-allergic
individuals. This study aimed to understand BLG's interactions with selected MPs (polyethylene
terephthalate, PET, <80μm; polypropylene, PP, 63-180μm). BLG, isolated from
unpasteurized/pasteurized milk, was incubated with PP and PET in simulated physiological fluids.
The resulting coronas were analyzed using reduced SDS-PAGE electrophoresis and densitometry.
BLG exhibited low binding to both MPs, with pasteurized BLG showing the lowest binding to PP
(less than 1% of control in its soft corona). There were differences in the protein content of hard
coronas between pasteurized and unpasteurized BLG, with a slightly higher percentage of bound
proteins in the hard corona of unpasteurized BLG. Additionally, the protein profile of hard coronas
differed between PET and PP incubated with pasteurized BLG compared to those with
unpasteurized BLG. These findings suggest that the presence of MPs may affect the bioavailability
and allergenic properties of both pasteurized and unpasteurized BLG., Interakcija mikroplastike (MP) s proteinima stvara kompleks poznat kao proteinska korona. U okviru korone, MP dobija nove biološke osobine, uključujući izbegavanje imunog sistema, dugotrajnije zadržavanje u cirkulaciji i ometanje ćelijskih procesa. Formiranje biofilma na površini MP je višestepeni proces, gde se nakon prvobitnog vezivanja molekula s visokim afinitetom i formiranja čvrste korone, može razviti i labavija korona u kasnijim fazama. β-laktoglobulin (BLG), glavni protein u surutki kravljeg mleka, često korišćen u hrani, može izazvati značajne zdravstvene probleme kod osoba alergičnih na mleko.

AB  - Green chemistry has emerged as a significant field in science in recent years due to
environmental concerns, the need to mitigate chemicals health hazards, regulatory
pressure, and economic benefits. This paper analyzes the trend of scientific publications on
green chemistry in Serbia over the last 10 years. For this purpose, data were retrieved from
the Scopus through a search for the study period, 2014-2024, limited to Serbia. In total, 96
records were retrieved. The results showed that green chemistry is increasingly prevalent
in different fields of knowledge in Serbia, with the highest percentages in chemistry
(22.1%), biochemistry, genetics, and molecular biology (19.1%), environmental science
(13.6%), The number of publications first peaked in 2018, decreasing in subsequent years
probably due to the COVID-19 pandemic, and then peaking again even more in 2022.
Concerning the type of publication, most publications are Articles (90.6%) and Reviews
(7.3%), with more than half affiliated with the University of Belgrade (56 documents). The
obtained results indicate that the green chemistry in Serbia is becoming more recognizable
among researchers in recent years, and it can be assumed that this interest will continue to
trend upwards.

AB  - BACKGROUND: Phycocyanobilin (PCB) is an open-chain blue tetrapyrrole chromophore of C-phycocyanin (C-PC), a major chromoprotein
derived from the cyanobacterium Arthrospira platensis having numerous health-promoting effects. Relying on the
ability of PCB to attach to the sulfhydryl group of proteins, we propose a new method for covalent attachment of PCB to bovine
serum albumin (BSA) as a means of its functionalization.
RESULTS: Traut's reagent (TR, 2-iminothiolane), modifying lysine residues, was used to optimize the introduction of sulfhydryl
groups in BSA. A higher degree of BSA thiolation by TR induces more profound alterations of its structure, resulting in minor
oligomerization and aggregation. A 50-fold molar excess of TR was found to be the optimal, balancing thiolation level and
adverse effect on protein structure. PCB was covalently attached to newly introduced sulfhydryl groups at pH 9 at 20-fold
PCB/BSA ratio. An increase in the TR/BSA molar ratio leads to increased efficiency of PCB conjugation with thiolated BSA. Compared
to native BSA, BSA–PCB conjugate binds quercetin with similar affinity but has higher antioxidant activity and increased
oxidative stability.
CONCLUSIONS: PCB-modified BSA could serve as a stable, food-compatible carrier of bioactive PCB, but also bind other ligands
that would be protected from oxidative damage due to the high antioxidant potential of covalently bound PCB. Thiolation by
TR is, at the same time, a simple method for the covalent functionalization of virtually any protein by bioactive PCB or for
obtaining PCB-based fluorescent probes.

AB  - Current knowledge of the microbiota of soda pans of the Carpathian Basin focuses mainly on diatoms. In studying six
soda pans in Vojvodina (Serbia), we aimed to gain deeper insights into the diatom community by using not only traditional
microscopic analysis but also high-throughput sequencing of the 18S rRNA gene. In addition, this study aimed to evaluate
bacterial communities in these soda pans for the first time using the 16S rRNA gene marker. Although similar numbers
of diatom taxa were found using both approaches, a significant discrepancy in species composition was found. The genus
Nitzschia was one of the most represented and numerous genera according to the morphological and molecular analyses,
but with lower diversity according to the molecular data, with the sequences mostly unassigned. Another major discrepancy
was noticed with taxon Halamphora veneta, the results of metabarcoding showed high abundance in almost all soda
pans, while microscopy detected it as very low. Diverse communities of aerobic and anaerobic bacteria were detected in
the studied soda pans, such as Proteobacteria, Bacteroidota, Actinobacteria, Bacillaceae, and Peptoclostridium. According
to current knowledge, harsh environmental conditions and habitat homogeneity regulate diatom and bacteria community
composition and enable the survival of taxa with predominantly high ecophysiological plasticity. Finally, uncovering the
structure of the microbial community as the first phase in developing an efficient tool to assess the ecological status of
these fragile ecosystems is an essential step towards their conservation.

AB  - The alkaline electrolytes of zinc are widely used in a Zn-air secondary batteries which represent promising candidate for energy storage with many advantages relative to the other types, such as Li-air, Al-air, and Mg-air batteries. These advantages are related with an abundance of Zn, low toxicity, and low cost, as well as by the fact that Zn possess a relatively high specific energy density. One of the largest problems in a development of Zn-air batteries is dendritic growth caused by the uneven deposition of zinc in the charging process. The solving of this problem implies the good knowledge of all phenomena related with Zn deposition, and regarding it, this study aims to establish a correlation between morphology and structure of electrolytically produced Zn irregular forms, especially Zn dendrites.

AB  - Electrodeposition of copper from deep eutectic solvents (DES) based on a mixture of choline chloride and
ethylene glycol containing CuCl2⋅2H2O at 50 ◦C and 80 ◦C was studied. Electrochemical reduction/oxidation of
Cu(II)/Cu(0) on glassy carbon (GC) and palladium (Pd) electrodes was investigated by cyclic voltammetry (CV)
and square wave voltammetry (SWV) emphasizing that this process takes place through two steps, Cu(II) ↔ Cu(I)
and Cu(I) ↔ Cu(0). The CV results showed that in chloride-rich DES electrolytes, the increased presence of chloro
ligands raises the overpotential required for Cu electrodeposition. The electrochemical impedance spectroscopy
(EIS) results indicate simultaneous electrodeposition of Cu and electrosorption of large cations on electrodeposited
Cu on both GC and Pd substrates. Scanning electron microscopy (SEM) results showed that Cu grains of
approximately 1 μm were obtained by electrodeposition of Cu on both Pd and GC, whereby better coverage by
electrodeposited Cu was obtained on Pd than on GC. Cu electrodeposited on Pd was relatively uniform and
smooth, but porous, while Cu electrodeposited on GC was dispersed in small agglomerates. Energy-dispersive Xray
spectroscopy (EDS) of Cu electrodeposited on Pd detected the dominant presence of Cu with the possibility of
the formation of CuPd alloy. The presence of CuPd alloy face-centred cubic structures is confirmed by X-ray
diffraction (XRD) along with metallic Cu.

AB  - The aim of this paper is to provide insight into research and activities of in situ remediation to remove petroleum hydrocarbon pollutants from a contaminated aquifer’s sediment, located near two radial collector wells of a water supply system. It was decided that the most appropriate method for remediation of this aquifer’s sediment is in situ bioremediation because it is clean, efficient and sustainable technology. Before the start of the bioremediation process, it was necessary to isolate and cultivate the microorganisms present at the contamination site, so they could be later applied in the bioremediation process. The samples before and after the bioremediation were studied using both GC and GC × GC–MS to determine how the concentrations of contaminants changed over time. Additionally, in this paper, a spatiotemporal representation of the change in hydrocarbon content by depth within the zone of the highest contamination over time is shown. After 12 months of bioremediation, the hydrocarbon content in the samples decreased by 82.0%, and based on GCxGC-MS analysis, the order of degradation of various hydrocarbon groups was as follows: steranes (99.6%), isoprenoids (98.4%), benzene derivatives (98.4%), alkanes (97.2%), and terpenes (49.3%). The exponential decay model showed the greatest decomposition rate of hydrocarbons occurred at depths of 8–10 m, with an average decay constant of 0.227, independent of the initial concentration of hydrocarbons. To the best of our knowledge, to date, the described approach has not been applied to an aquifer (the simultaneous treatment of groundwater and its associated sediment layers).

AB  - For a long time, Reversed-Phase Liquid Chromatography (RPLC) was the most dominant
technique for the analysis of pharmaceutical compounds, but with poor efficiency in the separation of
small polar molecules. From the efforts to solve the problem of insufficient retention of these molecules,
during the last decades, a mode of liquid chromatography named Hydrophilic Interaction Liquid
Chromatography (HILIC) has experienced vast expansion. It is based on the use of a highly hydrophilic
stationary phase along with an aqueous mobile phase with high organic modifier content. In
this review, the characteristics of stationary and mobile phases used in HILIC are described, and corresponding
separation mechanisms are discussed. An overview of recently published papers dealing
with the application of HILIC in analyzing pharmaceuticals in biological and non-biological samples
is provided. Besides, the application of HILIC systems in the determination of the physicochemical
properties of compounds is described.

AB  - Utilizing a data-driven approach, this study investigates modifier effects on compensation voltage in differential mobility spectrometry–mass spectrometry (DMS-MS) for metabolites and peptides. Our analysis uncovers specific factors causing signal suppression in small molecules and pinpoints both signal suppression mechanisms and the analytes involved. In peptides, machine learning models discern a relationship between molecular weight, topological polar surface area, peptide charge, and proton transfer-induced signal suppression. The models exhibit robust performance, offering valuable insights for the application of DMS to metabolites and tryptic peptides analysis by DMS-MS.

AB  - The continuous industrial chemical processes are typically designed through steady-state conditions. Nevertheless, there is evidence that processes can be intensified by applying optimized forced periodic operation. Possible improvements in reactor performances caused by the implementation of forced periodic operation (FPO) can be successfully evaluated by applying a nonlinear frequency response (NFR) analysis, before experimental investigation. In this study, we will present the results of two case studies based on heterogeneously catalyzed methanol synthesis in a continuous stirred tank reactor (CSTR). The first is an isothermal case, and the second is a more complicated and more realistic, non-isothermal case.

AB  - The purpose of this research is examining how the parent material and land use affect physico-chemical and mechanical characteristics of the urban forest soil with the final goal of defining soil degradation indicators. Total of 53 soils samples from the urban forest at the Fruska gora Mt. near Belgrade, Serbia, were analyzed for the following properties: pH, electrical conductivity, oxido-redox potential, content of organic carbon, concentration of available cations, aggregate size and stability. The soils were developed on five bedrock types: serpentinite, marl, trachyte, shale, loess and two land use types: forest and meadow. The correlation between the obtained parameters was tested with two-way ANOVA and principal component analyses (PCA).

AB  - Similarly to a phoenix, SARS-CoV-2 has appeared periodically in waves. The new variants that appeared through mutations have suppressed earlier variants, causing new waves of the pandemic. The Omicron BA.2.86 Pirola variant is the latest in the sequence. An increased infectivity was noticed, which results in rapid spreading, as well as decreased pathogenicity, which results in a lower number of severe cases. However, in the public there is a fear of further development of the epidemic. This analysis was made with the goal to assess the risks in the period of early 2024. Mutations that were developed by the BA.2.86 variant have led to a change in empirical formula and thermodynamic properties. The empirical formula of the BA.2.86 virus particle is CH1.639023O0.284130N0.230031P0.006440S0.003765. It is different than those of other variants of SARS-CoV-2, other virus species and cellular organisms. The driving force for virus multiplication, Gibbs energy of biosynthesis, of the BA.2.86 variant is -221.75 kJ C-mol-1. It is more negative than that of its host tissue. According to the biosynthesis phenomenological equation, the more negative Gibbs energy of biosynthesis allows the virus to achieve a greater biosynthesis rate and hijack the host cell metabolism. However, Gibbs energy of biosynthesis of the BA.2.86 variant is similar to those of the CH.1.1 and XBB.1.16 variants. This means that these variants should have similar multiplications rates and thus similar pathogenicity. Therefore, it seems that there is no ground for fear of an extensive spreading of severe forms, but there are reasons for caution and monitoring of the spreading of the epidemic and potential appearance of new mutations. Moreover, unlike the earlier pandemic waves, during the newest pandemic wave, infections with influenza, RSV and BA.2.86 variant simultaneously appeared, which deserves an analysis.

AB  - The plasma electrolytic oxidation process of Ti foil in the presence of a colloidal solution of Ag nanoparticles was used for the synthesis of exceptionally photocatalytically active Ag-doped TiO2 coatings. UV–Vis absorption spectroscopy was applied to follow the changes in the surface plasmon resonance band of the Ag nanoparticles as a function of the Ag:PO43− ratio in a phosphate-based electrolyte solution. Transmission electron microscopy revealed the size of the Ag nanoparticles in the range of 3–12 nm. The XRD patterns of the Ag-doped TiO2 coatings confirmed the crystalline anatase TiO2 phase regardless of the dopant concentration and without metallic Ag or crystalline Ag oxide forms. The typical porous morphology of the Ag–TiO2 coatings was observed by scanning electron microscopy. A significantly improved photocatalytic activity of the Ag–TiO2 coatings in the degradation process of the insecticide lindane (gamma isomer of benzene hexachloride) and test molecule methyl orange compared to pure TiO2 was determined using the GC technique. The degradation efficiency of Ag-doped TiO2 coatings is higher for lindane than for methyl orange.

AB  - The use of fossil fuels leads to environmental contamination during their extraction, processing and distribution. Microbial biodegradation provides a sustainable method for cleaning contaminated areas which follows the principles of sustainability. This paper presents the dynamics of biodegradation of hydrocarbon fractions of diesel oil, using Planomicrobium sp. and Rhodococcus sp. isolated from petroleum-contaminated sites. GC– MS analysis was employed to analyse abundances of the specific compounds such as n-alkanes, isoprenoids, sesquitepranes,
hopanes, steranes and aromatic compounds (naphthalene and its methylated homologues, phenanthrene and anthracene and their methylated homologues, and dibenzothiophene and its methylated homologues). The obtained results showed that after 30 days of biodegradation of diesel, a significant degradation was achieved, with almost complete degradation of n-alkanes and a decrease in the amount of sesquiterapanes. Rhodococcus sp. had
a higher efficiency in degradation of n-alkanes, while Planomicrobium sp. had a higher efficiency in the degradation of branched hydrocarbons. Both strains showed high activity in the biodegradation of sesquitepranes and demonstrate ability to degrade methylated phenanthrenes. Additionally, dimethyldibenzothiophenes
were almost completely degraded and removed from the system. This study presents the first comprehensive report on the GC–MS analysis of the diesel biodegradation pattern of the Planomicrobium sp., compared with the well-established Rhodococcus sp.

AB  - The concept of photocatalytic CO2 and H2O conversion to solar fuels and value-added products provides simultaneous solution for increased energy demands and environmental problems. However, the lack of efficient photocatalysts restrains the large-scale development of photocatalytic technology. In the present study, noble (Pt and Au) and transition metal (Ni) doped nanoflakes assembled on TiO2@carbon microrods with high surface area and rutile crystal structure is prepared via fast, versatile solvothermal method. The photocatalytic performance of the prepared nanocomposites was evaluated in two photocatalytic systems: CO2 reduction and hydrogen production via photoreforming. Pt-doped catalyst showed enhanced hydrogen production efficiency and increased CH4 selectivity, while Ni-doped catalyst exhibited remarkable CO2 reduction activity with higher selectivity towards CO. The mechanism of Pt-promoted CH4 formation and Ni- and Au-promoted CO formation was thoroughly discussed regarding kinetic and thermodynamic parameters.

AB  - Five celestine crystals are sampled from the (paleo)surface intervening between the late Miocene to Pleistocene basaltic sequences of the Jabal Eghei(Nuqay) volcanic province (southern Libya). The celestine specimens are characterized by applying the combination of the SEM-WDS, ICP/OES, XRPD, and IR methods. The celestine minerals are further analyzed for their color variations and minerogenetic framework. Three samples have greenish-blue-to-blue (480.4-482.5 nm), whereas the other two samples have blue-green color (cyan; 489.1-494.1 nm). The color purity ranges from 1.36-7.16. Their similarity of chemical content is fitting into the celestine near-end members, in which exclusively 1.6-4.1 at. % of Sr2+ content was substituted by Pb2+ (0.7-0.9 at. %), Ba2+ (0.5-0.7 at. %) and Ca2+ (0.2-0.8 at. %). The composition includes vacancies ranging from 1.0 to 1.9 at. % (observed only in three samples). The content of other chemical elements is minor. The resulting unit-cell parameters have the following ranges: a0=8.3578(9)-8.3705(6) Å; b0=5.3510(5)-5.3568(4) Å; c0=6.8683(7)-6.8767(2) Å and V0=307.17(5)-308.34(4) Å3. The XRPD and IR results are mainly in accordance with the SEM-WDS results, having a higher level of correlativity. However, the analysis exposed a few discrepancies yielding several possible interpretations. The illustrated discrepancies were primarily caused by a slight unit-cell axial anisotropy i.e., thermal expansion. In this manner, the results yield a new geothermometric tool that is based on the unit-cell axial anisotropy. The investigated Sr-bearing celestines were formed during a Miocene intraplate volcanism, basaltic magmas, and associated brines lifted by the structural conduits (normal faults crosscutting the Sirt basin). The Sr-bearing fluids were then poured into and over the faulted and fractured lagoon-type gypsum, anhydrite Eocene sediments. The celestine minerals were produced within a ~ 368-430K (~ 95-157 oC) temperature range. The celestine is formed at slightly elevated temperature and pressure conditions, close to the shallow subsurface environment (over 250 bars).
