abstract = {The study presents a mathematical model of Bruk Temkin-Gorodsky Novakovic (BT-GN) reaction system employing palladium-catalyzed oscillatory carbonylation reaction of mono alkyne-terminated poly(ethylene glycol) methyl ether. The proposed model advances simulation capabilities of this particular chemical oscillator but also BT-GN reactions in general. The model was verified using experimental data where good agreement is achieved and existence of complex pH oscillations like burst oscillations was matched. Furthermore, the model was used to predict reaction conditions capable of producing further complexities and initial conditions that would lead to desired period of pH oscillations. Having such a powerful tool, enhances our capabilities to study and further develop BT-GN oscillators with a reduced experimental effort. © 2022, Akadémiai Kiadó, Budapest, Hungary.},

abstract = {The interaction of a Transversely Excited Atmospheric (TEA) CO2 laser with a polymer polymethyl methacrylate (PMMA) sample in a vacuum ambiance was studied. The main goal was to demonstrate the feasibility of laser-induced breakdown spectroscopy (LIBS) to detect hydrogen. The generation of plasma over the PMMA surface, using a low laser intensity of ∼ 48 MW/cm2 and fluence of ∼ 16.5 J/cm2, required the application of a metal sub-target. Besides hydrogen, the recorded spectra were dominated by atomic lines of carbon and oxygen and band emission of the C2 and CN molecules. The electron number density and temperature (ionic, vibrational, and rotational) were evaluated to characterize the laser-induced plasma. In addition, PMMA micro-damages (diameter ∼ 45 µm) created by a multipulse laser ablation could find potential applications in sensor technologies. © 2021 Elsevier B.V.},

abstract = {Thiosemicarbazides are an important class of compounds with pronounced biological activities. In this contribution, the crystallographic structure of (E)-2-(2,5-dimethoxybenzylidene)hydrazinecarbothioamide (DBH) was described, and further spectroscopic studies (IR, Raman, 1H, and 13C NMR) studies were performed. Several density functional theory functionals (B3LYP, CAM-B3LYP, APFD, PBEPBE, M05-2X, and M06-2X) in conjunction with 6-311++G(d,p) were applied for the optimization of the structure. The highest resemblance to the crystallographic structure was obtained for structure optimized at M05-2X/6-311++G(d,p) level of theory. This structure was further used for the prediction of IR, Raman, and NMR spectra. The detailed vibrational and NMR analysis, with the most prominent bands assigned, proved that the experimental and theoretical spectra match well and that the obtained level of theory was suitable for the description of structure. Special emphasis was put on the analysis of dimers of DBH and water/DMSO-DBH structures to examine specific interactions. Natural Bond Orbital (NBO) and Quantum Atoms in Molecules (QTAIM) theories were applied for the quantification of the strength of these interactions. The most active positions were outlined through the calculation of the Fukui functions. A molecular docking study of DBH was performed towards Polo-like Kinase 1 (PLK1) to investigate the potential antitumor activity and the results were compared to volasertib. Specific interactions and binding affinities of monomers and dimers of DBH were discussed. © 2021 Elsevier B.V.},

abstract = {Organomodified bentonites were obtained by modification of bentonite clay from local mine Bogovina, with four different alkylammonium ions in the amounts that correspond to cation exchange capacity. Carbonized bentonites, obtained by pyrolyzing the organomodified bentonites in the flow of nitrogen, were characterized using XRD, low-temperature N2 physisorption and Raman spectroscopy. Structural and textural properties of carbonized bentonites depended on the arrangement of alkylammonium cations in the paternal organomodified bentonite, while the Raman spectroscopy confirmed the presence of amorphous carbon. The obtained carbonized bentonites were used for modification of the carbon paste electrode. The modified electrodes were investigated using cyclic voltammetry and electrochemical impedance spectroscopy. The electrosorption of chloride and sulfate anions on carbonized bentonites was studied by chronocoulometry.

Pure and Ce-exchanged ZSM-5 were immobilized on aluminum supports from a silicate-based electrolyte under ultra-low duty cycle pulsed direct current conditions. The obtained composite coatings were characterized with respect to their morphology, phase and chemical composition, as well as photocatalytic activity and anti-corrosion properties. All mentioned properties of the obtained coatings were dependent on the processing time. The coatings with Ce-exchanged ZSM-5 showed higher photocatalytic activity and more effective corrosion protection than those with pure ZSM-5. The highest photocatalytic activity was observed for coatings processed for 30 min.

abstract = {Removal of the β-blocker atenolol from an aqueous solution was studied using TiO2/zeolites, prepared by a simple and cost-effective solid-state dispersion method. Synthetic zeolites 13X and ZSM-5 (Si/Al = 40) and natural zeolite clinoptilolite were used as one component of the hybrid materials, whereas TiO2 nanocrystals obtained from TiO2 nanotubes and P25 TiO2 nanoparticles were used as the other. The synthesized materials were characterized by X-ray powder diffraction, transmission electron microscopy, Fourier transformed infrared spectroscopy, ultraviolet–visible diffuse reflectance spectroscopy and scanning electron microscopy with energy-dispersive spectroscopy. The photocatalytic activity for the degradation of atenolol was investigated under simulated solar light. Additionally, the effect of initial pH on atenolol removal and the reusability of prepared catalysts were tested. The best loading of TiO2 was 20 wt% over all investigated zeolites. The degradation of atenolol followed the pseudo-first-order kinetics. The photocatalytic degradation of atenolol after 70 min of irradiation was ~ 50% for TiO2/13X materials, ~ 45% for clinoptilolite combined with P25 TiO2 and ~ 57% for clinoptilolite combined with TiO2 nanocrystals obtained from TiO2 nanotubes. The results showed the highest removal efficiency after 70 min of irradiation for ZSM-5 combined with P25 TiO2 (~ 94%), followed by ZSM-5 combined with TiO2 nanocrystals obtained from TiO2 nanotubes (~ 88%) at near-neutral pH (~ 6.5). The total removal of atenolol from an aqueous solution for TiO2/ZSM-5 materials resulted from two processes: adsorption and photocatalytic degradation. The TiO2/ZSM-5 photocatalysts can be easily recovered and reused as their activity was preserved after four cycles. © 2022, The Author(s) under exclusive licence to Iranian Society of Environmentalists (IRSEN) and Science and Research Branch, Islamic Azad University.},

The crystal structure of the 4-hydroxycoumarin-octopamine derivative was solved and used as a starting geometry for structural optimization. Along with the previously obtained 4-hydroxycoumarin-dopamine derivative, the intramolecular interactions governing the stability of these compounds were quantified by NBO and QTAIM analyses. Condensed Fukui functions and the HOMO-LUMO gap were calculated and correlated with the number and position of OH groups in the structures. In vitro cytotoxicity experiments were performed to elucidate the possible antitumor activity of the tested substances. For this purpose, four cell lines were selected, namely human colon cancer (HCT-116), human adenocarcinoma (HeLa), human breast cancer (MDA-MB-231), and healthy human lung fibroblast (MRC-5) lines. A significant selectivity towards colorectal carcinoma cells was observed. Molecular docking and molecular dynamics studies with carbonic anhydrase, a prognostic factor in several cancers, complemented the experimental results. The calculated MD binding energies coincided well with the experimental activity, and indicated 4-hydroxycoumarin-dopamine and 4-hydroxycoumarin-3-methoxytyramine as the most active compounds. The ecotoxicology assessment proved that the obtained compounds have a low impact on the daphnia, fish, and green algae population. © 2022 by the authors.},

XPS analysis showed that the atomic percentages of Au and Pt in PtAu/rGO were 0.6% and 0.3%, respectively. The atomic percentage of Au alone on previously prepared Au/rGO was 0.7%. Outstanding HER activity was achieved for the PtAu/rGO electrode, showing the initial potential close to the equilibrium potential for HER and a low Tafel slope of −38 mV/dec. This was confirmed by electrochemical impedance spectroscopy.

Composites were reduced using ascorbic acid.

Without the presence of NPs, the intensities of analyte lines were very low, unsuitable for spectrochemical analysis.

abstract = {Dual templating approach, using hexadecyltrimethylammonium bromide (CTAB), was employed in an attempt to synthesize hierarchical ZSM-5 zeolite. Amount of mesoporogen and the duration of aging of the precursor were varied. Majority of the synthesis routes resulted in phase separation, yielding separate ZSM-5 and amorphous mesoporous material. The relative amounts of the two phases were dependent on the CTAB amount ratio and also significantly on the duration of precursor aging before CTAB addition. One particular combination of the two factors led to the formation of a homogeneous hierarchical form of ZSM-5 with leafy morphology, consisting of intergrown thin crystalline sheets which formed flower-like structures. The hierarchical ZSM-5 possessed significant microporous (≈95 m2/g) and highly developed mesoporous surface (≈470 m2/g), with a relatively broad distribution of mesopore sizes (<20 nm). The acidity of all samples was studied in detail. Isothermal microcalorimetry/volumetry of ammonia adsorption provided quantitative data on the number and distribution of strength of acidic sites. In situ FTIR of pyridine and collidine adsorption was used to quantify Brønsted and Lewis acid sites, and to provide information on their location - in the micropores or mesopores/external surface. The hierarchical ZSM-5 possessed both Lewis and Brønsted acidity, with Brønsted sites located mainly in the micropores. All samples were fully characterized using XRD, low temperature nitrogen adsorption, FESEM and EDS. The synthetic route used for obtaining the ZSM-5 zeolite with flower-like morphology is a simple strategy for preparing hierarchical ZSM-5 forms targeting enhanced diffusivity and accessibility of catalytically active sites. © 2021 Elsevier Inc.},

abstract = {Background The utility of intravoxel incoherent motion (IVIM) related parameters in differentiation of hypovascular liver lesions is still unknown. Purpose The purpose of this study was to evaluate the value of IVIM related parameters in comparison to apparent diffusion coefficient (ADC) for differentiation among intrahepatic mass-forming cholangiocarcinoma (IMC), and hypovascular liver metastases (HLM). Methods Seventy-four prospectively enrolled patients (21 IMC, and 53 HLM) underwent 1.5T magnetic resonance examination with IVIM diffusion-weighted imaging using seven b values (0-800 s/mm2). Two independent readers performed quantitative analysis of IVIM-related parameters and ADC. Interobserver reliability was tested using a intraclass correlation coefficient. ADC, true diffusion coefficient (D), perfusion-related diffusion coefficient (D*), and perfusion fraction (ƒ) were compared among the lesions using Kruskal-Wallis H test. The diagnostic accuracy of each parameter was assessed by receiver operating characteristic (ROC) curve analysis. Results The interobserver agreement was good for ADC (0.802), and excellent for D, D*, and ƒ (0.911, 0.927, and 0.942, respectively). ADC, and D values were significantly different among IMC and HLM (both p < 0.05), while there was no significant difference among these lesions for ƒ and D* (p = 0.101, and p = 0.612, respectively). ROC analysis showed higher diagnostic performance of D in comparison to ADC (AUC = 0.879 vs 0.821). Conclusion IVIM-derived parameters in particular D, in addition to ADC, could help in differentiation between most common hypovascular malignant liver lesions, intrahepatic mass-forming cholangiocarcinoma and hypovascular liver metastases.

abstract = {Environmental implementation of novel composite materials comprising potassium tungstophosphate (KPW) and ZSM-5 zeolite was tested in ethene production and pesticide removal. The study revealed that the binding of KPW to ZSM-5 zeolites of different Si/Al ratios affects the formation of active centres for catalytic and adsorption processes. Brønsted active sites present in the zeolite framework are synergistically joined with Lewis centres and additional Brønsted centres through the impregnation of potassium tungstophosphate, which resulted in improvement of stability and activity of investigated materials. Adsorption and catalytic performance were found to be influenced by the order of addition of salt precursors and by post-synthesis thermal treatment. The best results found both in ethanol dehydration and nicosulfuron removal were for the same sample of KPW supported at zeolite ZSM-5 (SiO2/Al2O3 = 30). The prominent ethanol conversion of 98% and the highest and most stable selectivity toward ethene were evidenced, along with the capacity of 28.4 mg of targeted pesticide retained per gram of designed KPW/ZSM composite. This comprehensive investigation enabled insight into active site formations in the efficient KPW/ZSM composites. Different approaches to implementation revealed that a lower Si/Al ratio in zeolite promotes efficient K+ exchange, which combined with two-phased in situ preparation of KPW as active phase, evidently leads to the formation of isolated sites of superior activity for both catalytic and adsorptive procedures. © 2021},

The analytical capability of LIBS in identification of elements characteristic to inorganic pigments used for decoration was assessed. Based on the specific elements detected in the LIBS spectra of glazes, correlations between the elemental composition of the glaze and the colours of the glazed surface were established. The results were in accordance with the previously reported Energy Dispersive X-ray Fluorescence (EDXRF) and Raman analyses of some of the samples, and with the presently performed XRF analysis. Two important parameters for plasma characterization, temperature and electron number density, were estimated from the spectral data. A potential use of LIBS for depth profiling was also investigated by analysing the silicon to aluminium intensity ratio as a function of the number of laser shots applied. Profilometry analysis of the damages created on the glazed surfaces by laser shots was used to estimate the average ablation depth and ablated mass. © 2020 Elsevier Ltd},

abstract = {In this study, the preparation of some large-pore ordered mesoporous silicas using a proper surfactant with different swelling agents was carried out. The synthesis of conventional SBA-15 was modified to obtain pore-expanded materials, with pore diameters up to 10 nm. To use a micelle swelling agent with a moderate swelling ability, three swelling agents were selected: 1-phenyl-decane (Dec), butyl benzene (BB), and mesitylene (Mes). These syntheses aimed to achieve a pore diameter enlargement but at the same time to avoid the formation of heterogeneous and/or poorly defined nanostructure of silica. The CO2 adsorbents were obtained by post-synthesis functionalization treatments carried out by grafting with 3-aminopropyl triethoxysilane. The CO2 adsorption/desorption experiments showed that carbon dioxide sorption capacities depend on the textural characteristics and the temperature used for the adsorption process. Good CO2 adsorption capacities were obtained for all prepared adsorbents, especially for SSBA-15-Mes-sil and SSBA-15-BB-sil samples. At 50 °C, the SSBA-15-Mes-sil sample has an adsorption capacity of 3.58 mmol CO2/g SiO2, and an efficiency of amino groups of 0.99 mmol CO2/mmol NH2. The results of adsorption capacities are comparable or even superior with the ones reported in literature for mesoporous silica functionalized with different amines. After nine adsorption–desorption cycles, the performance of the SSBA-15-Mes-sil adsorbent is relatively stable, with a low decrease in the adsorption capacity (0.1 mmol/g of CO2, i.e., 2.8% of initial capacity). These studies show the potential of mesoporous silica for carbon dioxide capture. © 2020, Springer Science+Business Media, LLC, part of Springer Nature.},

In this contribution, the crystallographic structure of (E)-2-(2,5-dimethoxybenzylidene)hydrazinecarbothioamide (DBH) was described, and further spectroscopic studies (IR, Raman, 1H, and 13C NMR) studies were performed. Several density functional theory functionals (B3LYP, CAM-B3LYP, APFD, PBEPBE, M05-2X, and M06-2X) in conjunction with 6-311++G(d,p) were applied for the optimization of the structure. The highest resemblance to the crystallographic structure was obtained for structure optimized at M05-2X/6-311++G(d,p) level of theory. This structure was further used for the prediction of IR, Raman, and NMR spectra. The detailed vibrational and NMR analysis, with the most prominent bands assigned, proved that the experimental and theoretical spectra match well and that the obtained level of theory was suitable for the description of structure. Special emphasis was put on the analysis of dimers of DBH and water/DMSO-DBH structures to examine specific interactions. Natural Bond Orbital (NBO) and Quantum Atoms in Molecules (QTAIM) theories were applied for the quantification of the strength of these interactions. The most active positions were outlined through the calculation of the Fukui functions. A molecular docking study of DBH was performed towards Polo-like Kinase 1 (PLK1) to investigate the potential antitumor activity and the results were compared to volasertib. Specific interactions and binding affinities of monomers and dimers of DBH were discussed. © 2021 Elsevier B.V.},

Synthetic zeolites 13X and ZSM-5 (Si/Al = 40) and natural zeolite clinoptilolite were used as one component of the hybrid materials, whereas TiO2 nanocrystals obtained from TiO2 nanotubes and P25 TiO2 nanoparticles were used as the other. The synthesized materials were characterized by X-ray powder diffraction, transmission electron microscopy, Fourier transformed infrared spectroscopy, ultraviolet–visible diffuse reflectance spectroscopy and scanning electron microscopy with energy-dispersive spectroscopy. The photocatalytic activity for the degradation of atenolol was investigated under simulated solar light. Additionally, the effect of initial pH on atenolol removal and the reusability of prepared catalysts were tested. The best loading of TiO2 was 20 wt% over all investigated zeolites. The degradation of atenolol followed the pseudo-first-order kinetics. The photocatalytic degradation of atenolol after 70 min of irradiation was ~ 50% for TiO2/13X materials, ~ 45% for clinoptilolite combined with P25 TiO2 and ~ 57% for clinoptilolite combined with TiO2 nanocrystals obtained from TiO2 nanotubes. The results showed the highest removal efficiency after 70 min of irradiation for ZSM-5 combined with P25 TiO2 (~ 94%), followed by ZSM-5 combined with TiO2 nanocrystals obtained from TiO2 nanotubes (~ 88%) at near-neutral pH (~ 6.5). The total removal of atenolol from an aqueous solution for TiO2/ZSM-5 materials resulted from two processes: adsorption and photocatalytic degradation. The TiO2/ZSM-5 photocatalysts can be easily recovered and reused as their activity was preserved after four cycles. © 2022, The Author(s) under exclusive licence to Iranian Society of Environmentalists (IRSEN) and Science and Research Branch, Islamic Azad University.},

The crystal structure of the 4-hydroxycoumarin-octopamine derivative was solved and used as a starting geometry for structural optimization. Along with the previously obtained 4-hydroxycoumarin-dopamine derivative, the intramolecular interactions governing the stability of these compounds were quantified by NBO and QTAIM analyses. Condensed Fukui functions and the HOMO-LUMO gap were calculated and correlated with the number and position of OH groups in the structures. In vitro cytotoxicity experiments were performed to elucidate the possible antitumor activity of the tested substances. For this purpose, four cell lines were selected, namely human colon cancer (HCT-116), human adenocarcinoma (HeLa), human breast cancer (MDA-MB-231), and healthy human lung fibroblast (MRC-5) lines. A significant selectivity towards colorectal carcinoma cells was observed. Molecular docking and molecular dynamics studies with carbonic anhydrase, a prognostic factor in several cancers, complemented the experimental results. The calculated MD binding energies coincided well with the experimental activity, and indicated 4-hydroxycoumarin-dopamine and 4-hydroxycoumarin-3-methoxytyramine as the most active compounds.

abstract = {The need for stable, chemical resistant and conductive materials is on the rise in recent times. Graphene shows promising electrical conductivity and chemical stability, but the production of a continual, conductive layer is limited and expensive. Silver nanowires (AgNWs) are both conducive and economically viable, but they are sensitive to water and oxygen. In this study, graphene oxide (GO) and AgNWs were synthesized and combined in different mass ratios (3:1, 2.5:1.5, and 1:1) to obtain chemically stable composites with improved electrical properties. Composites were reduced using ascorbic acid. With the increase of AgNWs to GO mass ratio, the surface of the free-standing composite film improved: the root mean square roughness was lowered from 376 nm for GO to 168 nm for the composite with the mass ratio of GO:AgNWs 1:1, while the sheet resistance was lowered from 146 × 106 Ω/□ to 4 Ω/□. For the first time, the effects of gamma irradiation on the structure of the composites were studied. Doses of 15, 25, and 35 kGy were applied. © 2021 Elsevier B.V.},

abstract = {The analytical potential of LIBS for the analysis of liquid solutions was evaluated using two experimental setups, one based on a TEA CO2 laser and the other in which Nd:YAG laser was used. Polytetrafluoroethylene (PTFE) was used as a substrate on which a 10 μL drop of analyte solutions with different concentrations of analyte elements, Be, Cr, Ni, Co, Pb, Tl, and V, were deposited and dried. The samples were deposited either directly on the PTFE or over the pre-deposited layer of copper oxide nanoparticles to study the influence of nanoparticles (NPs) on the ablation and plasma excitation. The obtained results imply that the presence of Cu oxide NPs does not significantly affect the analytical performance of LIBS based on TEA CO2 laser for analysis of solutions. At the same time, it was shown that plasma created by TEA CO2 laser radiation efficiently excited ablated material, making metal elements detectable in the sub-ppm concentration range. On the other hand, Cu oxide NPs significantly influence the formation and the analytical properties of plasma induced by Nd:YAG laser. Without the presence of NPs, the intensities of analyte lines were very low, unsuitable for spectrochemical analysis. At the optimal surface concentration of NPs, 0.36 mg/cm2, the intensity of analyte lines was increased more than ten times. Limits of detection of Be and Cr were 5.3 ppb and 33 ppb, with good linearity of curves of growth. © 2021 Elsevier B.V.},

abstract = {Dual templating approach, using hexadecyltrimethylammonium bromide (CTAB), was employed in an attempt to synthesize hierarchical ZSM-5 zeolite. Amount of mesoporogen and the duration of aging of the precursor were varied. Majority of the synthesis routes resulted in phase separation, yielding separate ZSM-5 and amorphous mesoporous material. The relative amounts of the two phases were dependent on the CTAB amount ratio and also significantly on the duration of precursor aging before CTAB addition. One particular combination of the two factors led to the formation of a homogeneous hierarchical form of ZSM-5 with leafy morphology, consisting of intergrown thin crystalline sheets which formed flower-like structures. The hierarchical ZSM-5 possessed significant microporous (≈95 m2/g) and highly developed mesoporous surface (≈470 m2/g), with a relatively broad distribution of mesopore sizes (<20 nm). The acidity of all samples was studied in detail. Isothermal microcalorimetry/volumetry of ammonia adsorption provided quantitative data on the number and distribution of strength of acidic sites. In situ FTIR of pyridine and collidine adsorption was used to quantify Brønsted and Lewis acid sites, and to provide information on their location - in the micropores or mesopores/external surface. The hierarchical ZSM-5 possessed both Lewis and Brønsted acidity, with Brønsted sites located mainly in the micropores. All samples were fully characterized using XRD, low temperature nitrogen adsorption, FESEM and EDS. The synthetic route used for obtaining the ZSM-5 zeolite with flower-like morphology is a simple strategy for preparing hierarchical ZSM-5 forms targeting enhanced diffusivity and accessibility of catalytically active sites. © 2021 Elsevier Inc.},

abstract = {Background The utility of intravoxel incoherent motion (IVIM) related parameters in differentiation of hypovascular liver lesions is still unknown. Purpose The purpose of this study was to evaluate the value of IVIM related parameters in comparison to apparent diffusion coefficient (ADC) for differentiation among intrahepatic mass-forming cholangiocarcinoma (IMC), and hypovascular liver metastases (HLM). Methods Seventy-four prospectively enrolled patients (21 IMC, and 53 HLM) underwent 1.5T magnetic resonance examination with IVIM diffusion-weighted imaging using seven b values (0-800 s/mm2). Two independent readers performed quantitative analysis of IVIM-related parameters and ADC. Interobserver reliability was tested using a intraclass correlation coefficient. ADC, true diffusion coefficient (D), perfusion-related diffusion coefficient (D*), and perfusion fraction (ƒ) were compared among the lesions using Kruskal-Wallis H test. The diagnostic accuracy of each parameter was assessed by receiver operating characteristic (ROC) curve analysis. Results The interobserver agreement was good for ADC (0.802), and excellent for D, D*, and ƒ (0.911, 0.927, and 0.942, respectively). ADC, and D values were significantly different among IMC and HLM (both p < 0.05), while there was no significant difference among these lesions for ƒ and D* (p = 0.101, and p = 0.612, respectively). ROC analysis showed higher diagnostic performance of D in comparison to ADC (AUC = 0.879 vs 0.821). Conclusion IVIM-derived parameters in particular D, in addition to ADC, could help in differentiation between most common hypovascular malignant liver lesions, intrahepatic mass-forming cholangiocarcinoma and hypovascular liver metastases.

abstract = {Environmental implementation of novel composite materials comprising potassium tungstophosphate (KPW) and ZSM-5 zeolite was tested in ethene production and pesticide removal. The study revealed that the binding of KPW to ZSM-5 zeolites of different Si/Al ratios affects the formation of active centres for catalytic and adsorption processes. Brønsted active sites present in the zeolite framework are synergistically joined with Lewis centres and additional Brønsted centres through the impregnation of potassium tungstophosphate, which resulted in improvement of stability and activity of investigated materials. Adsorption and catalytic performance were found to be influenced by the order of addition of salt precursors and by post-synthesis thermal treatment. The best results found both in ethanol dehydration and nicosulfuron removal were for the same sample of KPW supported at zeolite ZSM-5 (SiO2/Al2O3 = 30). The prominent ethanol conversion of 98% and the highest and most stable selectivity toward ethene were evidenced, along with the capacity of 28.4 mg of targeted pesticide retained per gram of designed KPW/ZSM composite. This comprehensive investigation enabled insight into active site formations in the efficient KPW/ZSM composites. Different approaches to implementation revealed that a lower Si/Al ratio in zeolite promotes efficient K+ exchange, which combined with two-phased in situ preparation of KPW as active phase, evidently leads to the formation of isolated sites of superior activity for both catalytic and adsorptive procedures. © 2021},

The analytical capability of LIBS in identification of elements characteristic to inorganic pigments used for decoration was assessed. Based on the specific elements detected in the LIBS spectra of glazes, correlations between the elemental composition of the glaze and the colours of the glazed surface were established. The results were in accordance with the previously reported Energy Dispersive X-ray Fluorescence (EDXRF) and Raman analyses of some of the samples, and with the presently performed XRF analysis. Two important parameters for plasma characterization, temperature and electron number density, were estimated from the spectral data. A potential use of LIBS for depth profiling was also investigated by analysing the silicon to aluminium intensity ratio as a function of the number of laser shots applied. Profilometry analysis of the damages created on the glazed surfaces by laser shots was used to estimate the average ablation depth and ablated mass. © 2020 Elsevier Ltd},

abstract = {In this study, the preparation of some large-pore ordered mesoporous silicas using a proper surfactant with different swelling agents was carried out. The synthesis of conventional SBA-15 was modified to obtain pore-expanded materials, with pore diameters up to 10 nm. To use a micelle swelling agent with a moderate swelling ability, three swelling agents were selected: 1-phenyl-decane (Dec), butyl benzene (BB), and mesitylene (Mes). These syntheses aimed to achieve a pore diameter enlargement but at the same time to avoid the formation of heterogeneous and/or poorly defined nanostructure of silica. The CO2 adsorbents were obtained by post-synthesis functionalization treatments carried out by grafting with 3-aminopropyl triethoxysilane. The CO2 adsorption/desorption experiments showed that carbon dioxide sorption capacities depend on the textural characteristics and the temperature used for the adsorption process. Good CO2 adsorption capacities were obtained for all prepared adsorbents, especially for SSBA-15-Mes-sil and SSBA-15-BB-sil samples. At 50 °C, the SSBA-15-Mes-sil sample has an adsorption capacity of 3.58 mmol CO2/g SiO2, and an efficiency of amino groups of 0.99 mmol CO2/mmol NH2. The results of adsorption capacities are comparable or even superior with the ones reported in literature for mesoporous silica functionalized with different amines. After nine adsorption–desorption cycles, the performance of the SSBA-15-Mes-sil adsorbent is relatively stable, with a low decrease in the adsorption capacity (0.1 mmol/g of CO2, i.e., 2.8% of initial capacity). These studies show the potential of mesoporous silica for carbon dioxide capture. © 2020, Springer Science+Business Media, LLC, part of Springer Nature.},
