AB  - Studying the interaction of inorganic systems with organic ones is a highly important avenue for finding new drugs and treatment methods. Tumor cells show an increased demand for amino acids due to their rapid proliferation; thus, targeting their metabolism is becoming a potential oncological therapeutic strategy. One of the inorganic materials that show antitumor properties is titanium dioxide, while its doping was found to enhance interactions with biological systems. Thus, in this study, we investigated the energy landscape of glutamine (L), an amino acid, on pristine and doped TiO2 surfaces. We first locally optimized 2D-slab structures of pristine and Au/Ag/Cu-doped anatase (001 and 101 surfaces) and similarly optimized a single molecule of glutamine in vacuum. Next, we placed the pre-optimized glutamine molecule in various orientations and on a variety of locations onto the relaxed substrate surfaces (in vacuum) and performed ab initio relaxations of the molecule on the substrate slabs. We employed the DFT method with a GGA-PBE functional implemented in the Quantum Espresso code. Comparisons of the optimized conformations and electronic structures of the amino acid in vacuum and on the surfaces yield useful insights into various biological processes.

AB  - Calcium carbonate and gypsum are very common and widespread minerals widely used in many fields. However, in order to investigate their behavior under extreme conditions of pressure and temperature, a data-mining ab initio approach has been performed. To analyze structural stability and explore different CaCO3 and gypsum phases in these extreme conditions, the most interesting modifications have been submitted to the DFT calculations. Local optimizations have been performed using the CRYSTAL17 solid-state-quantum-chemical program. Total energies of different gypsum phases are presented and it seems that among the calcite phases, the Calcite I (CaCO3 I) phase has the lowest calculated total energy using the three different functionals in agreement with experimental data. Each of the modified phases of these minerals has been discussed and presented in this study. Due to the very wide industrial and technological application of these natural minerals, further investigation could be of great importance, especially their performances in extreme environments.

AB  - The Cr−Si−N system is of great interest for materials with advanced tribological and mechanical properties. So far, experimental data have been reported on Cr−Si−N coating, nanocrystalline phases, and thin films, together with theoretically predicted 1D and 2D hetero-structures, and 3D bulk Cr2SiN4 modifications. This study predicts possible bulk Cr−Si−N phases with the composition CrSi2N4. A multi-methodological approach has been employed to explore the system's energy landscape, where global optimization was combined with data mining and the Primitive Cell for Atom Exchange (PCAE) method. Local optimization of the structure candidates was performed on the DFT level using the GGA-PBE and the LDA-PZ approximation. The ten energetically most favorable structure candidates discovered in the CrSi2N4 chemical system mostly exhibited monoclinic symmetry but with a variety of structural features, from zeolite-like structures to polytypic behavior. Finally, the bulk modulus of these possible modifications was computed for a pressure range of up to 10 GPa.

AB  - Crystalline TiO2 has many practical applications as a photocatalytic material. The structures and relative energies of eleven different modifications of bulk structures with TiO2 composition were theoretically investigated in this study. Calculations were performed by the DFT method with LDA-PZ functional as implemented in CRYSTAL17 code. Structural parameters, energy- volume curves and electronic band gaps were calculated and analyzed. This study aimed to gain insight into the electronic structure of various modifications of crystalline pristine TiO2 and their phase transitions especially applicable at extreme pressure and temperature conditions. The information obtained in this study may contribute to future research on the structure and various properties (electronic, mechanical…) of such systems, as well as their potential application in various scientific fields and advanced technology.

AB  - The interfacial charge transfer (ICT) complex formation between zirconium dioxide (ZrO2), the material absorbing below 250 nm, and 5-aminosalicylic acid (5-ASA) leads to the formation of visible-light-absorbing inorganic–organic hybrids. The free amino groups, present on the hybrid's surface after the ICT complex formation, were used to reduce silver ions and link silver particles to ZrO2. The prepared samples were characterized by using transmission electron microscopy, X-ray diffraction analysis, and nitrogen adsorption–desorption isotherms. Density functional theory (DFT) calculations using a cluster model are applied to explain optical changes in hybrids, i.e., absorption redshift induced by the ICT complex formation. Decolorization of an organic dye crystal violet (CV), under ultraviolet-C or visible light, was used to compare the photocatalytic ability of the prepared samples. The ICT complex formation transformed ZrO2 into a hybrid material able to induce photocatalytic reactions under exclusive visible light excitation.

AB  - The nanostructured powderwas synthesized by the glycine nitrate procedure (GNP) because it proved to be the most effective and simplest method suitable for controlling the composition and morphology of Co0.9Ho0.1MoO4. To prepare nanostructured Co0.9Ho0.1MoO4, metal nitrates, and glycine were mixed in appropriate stoichiometric ratios. For the preparation of the technologically important Co0.9Ho0.1MoO4, the combustion process has proven to be a promising method that achieves control of stoichiometry, homogeneity, and purity. The synthesized samples were examined by DTA, X-ray diffraction (XRD), Fourier transform infrared (FT-IR) spectra, Spectroscopy, Field emission scanning electron microscopy (FESEM), and nitrogen adsorption method. The acquired nanopowder showed a tendency for agglomeration, inhomogeneous microstructure, and plate-like crystals. The photocatalytic activity of the obtained Co0.9Ho0.1MoO4nanopowders was evaluated by the photocatalytic degradation of crystal violet in an aqueous solution. After photocatalytic testing and all the above-mentioned characterizations, it was shown that these nanostructured materials represent promising solutions in photocatalytic processes toward green chemistry and sustainable development.

AB  - Nanometric size Co0.9Ho0.1MoO4 powder particles were obtained by applying glycine nitrate procedure (GNP). Powder properties have been studied by DTA, X-ray diffraction (XRD), Fourier transform infrared (FT-IR) spectra, Spectroscopy, Field emission scanning electron microscopy (FESEM), and nitrogen adsorption method. The photocatalytic activity of acquiring Co0.9Ho0.1MoO4 nanopowders was estimated by the photocatalytic degradation of crystal violet in an aqueous solution. We present a simple and effective method for controlling the composition and morphology of Co0.9Ho0.1MoO4, as well as a possible new approach in inorganic synthesis methodology. During photocatalytic testing, the studied nanoparticle powder indicated a potentially promising solution in photocatalytic processes toward green chemistry and sustainable development.

AB  - Silicon borides are lightweight ceramics and are regarded as the most elusive refractory compounds. Owing to their remarkable features, represent very appealing industrial materials for research. Although silicon hexaboride is discovered at the beginning of the XX century, there is a surprisingly limited number of studies on the elastic and mechanical properties of SiB6, both in theory and experiment. İn order to investigate the properties of this compound, first we have undertaken calculations using the ab initio minimization data mining approach [1,2] combined with the PCAE method [3], and several promising structure candidates have been found referred to as αSiB6, β-SiB6, and γ-SiB6 modifications. For these most relevant modifications, elastic constants Cij have been calculated using GGA-PBE and LDA-PZ approach and were compared to previous theoretical data. Cubic γ-SiB6 modification has only three independent elastic constants which are in very good agreement with available theoretical data. Using the elastic constants, mechanical stability was investigated and the results suggest instability in the cubic γ-SiB6 structure, which is also in agreement with previous theoretical studies. Elastic constants for the α-SiB6 phase are reported for the first time and indicate the mechanical stability of this phase. The last one, the βSiB6 phase has a lower orthorhombic symmetry and a larger number of independent elastic constants that were calculated using both the LDA and GGA approach and the results agree well with previous studies. According to the calculated results, the β phase is mechanically stable that also concurs with previous studies. Within this study, the bulk modulus B, Shear modulus K, Young’s modulus E, Poisson’s ratio v, and Pugh’s criterion B/K for these modifications have been calculated [4]. According to the calculated Poison’s ratio and Pugh’s criterion (B/K) using both GGA and LDA methods, it can be assumed that the β-SiB6 phase will have a brittle character, while α and γ-phase seem to be ductile. As it was suggested from several earlier studies that SiB6 has excellent potential as high-temperature material, and it has been considered as a material with the ability to operate in extreme environments, further research of this compound is required. Investigation in detail of these newly discovered phases and their properties is of great importance in order to find new possibilities for future industrial and technological applications.

AB  - Nanoemulsion technique based on Ouzo effect was applied for the fast and simple synthesis of Ag3PO4 at room temperature. X-ray powder diffraction analysis and Raman spectroscopy reviled that synthesized powder was single-phase. Using scanning electron microscopy analysis, it was found that the synthesized Ag3PO4 particles were near-spherical shape with an average diameter of 100 nm. The high value for the specific surface area of obtained powder was measured by Brunauer–Emmet–Teller method. Finally, the Ag3PO4 product was used as a photocatalyst for the photodegradation of crystal violet dye in an aqueous solution. Nanoemulsion strategy procedure provides a simple pathway to obtain a highly efficient single-phase Ag3PO4 photocatalyst.

AB  - Spider silk-maghemite (SS-γ-Fe2O3) composite was obtained by simple and fast co-precipitation method at room temperature. The fibers were coated with maghemite nanoparticles with the average size of 25 nm. According to DTA, maghemite NPs contributed the thermal stability of the composite. Magnetic properties of as obtained composite were estimated. At room temperature, the system was is in a superparamagnetic state, while at temperature of 5 K the magnetic moments were blocked. This composite is seen as a novel hybrid material with superparamagnetic properties for possible applications in bioseparation, biosensors, magnetographic printing, magnetic screens, and magnetic filters as well as sensing/actuating components of MEMS.

AB  - The antibacterial performance and cytotoxic examination of in situ prepared silver nanoparticles (Ag NPs), on inorganic-organic hybrid nanopowder consisting of zirconium dioxide nanoparticles (ZrO2 NPs) and dihydroquercetin (DHQ), was performed against Gram (−) bacteria Escherichia coli and Gram (+) bacteria Staphylococcus aureus, as well as against human cervical cancer cells HeLa and healthy MRC-5 human cells. The surface modification of ZrO2 NPs, synthesized by the sol-gel method, with DHQ leads to the interfacial charge transfer (ICT) complex formation indicated by the appearance of absorption in the visible spectral range. The prepared samples were thoroughly characterized (TEM, XRD, reflection spectroscopy), and, in addition, the spectroscopic observations are supported by the density functional theory (DFT) calculations using a cluster model. The concentration- and time-dependent antibacterial tests indicated a complete reduction of bacterial species, E. coli and S. aureus, for all investigated concentrations of silver (0.10, 0.25, and 0.50 mg/mL) after 24 h of contact. On the other side, the functionalized ZrO2 NPs with DHQ, before and after deposition of Ag NPs, do not display a significant decrease in the viability of HeLa MRC-5 cells in any of the used concentrations compared to the control.

AB  - Nanosized CoMoO4 solid solution was successfully synthesized at room temperature using simple and fast Self Propagating Room Temperature procedure (SPRT). The structural, textural, morphological and surface characteristics of the nanosized CoMoO4 were examined in detail by X-ray diffraction (XRD), Fourier transform infrared (FT-IR) spectra, Field emission scanning electron microscopy (FESEM), and nitrogen sorption method. X-ray powder diffraction (XRPD) reflected the presence of two different phases that are in the same space group. The α-CoMoO4 and the β-CoMoO4 modification crystallizes in the monoclinic space group C2/m, No.12, but the β-phase clearly distinct from the α-phase due to the tetrahedral coordination of the Mo6+ ions. Adsorption tests were studied over CoMoO4 nanopowders under different experimental conditions (material dosage, initial concentration of pollutant textile dye, etc). The obtained results showed acceptable sorption characteristics of the material.

AB  - The essence of this study is synthesis of a newly developed and efficient heterogeneous catalyst based on aluminum oxide support promoted with potassium iodide (KI) as active dopant responsible for pronounced catalyst activity. Modified sol–gel, reflux and hydrothermal method were used for synthesis of aluminum-oxide support using aluminum isopropoxide as a precursor. The γ-Al2O3 support and KI/γ-Al2O3 catalyst samples were examined by various experimental techniques. Effects of several operational parameters were considered and those are: methanol to sunflower oil molar ratio, catalyst loadings, reaction time and reaction stirring rate. The obtained results indicated that modified sol–gel method for synthesis of γ-Al2O3 catalyst support is the most favorable for obtaining the catalyst with superior catalytic performances in transesterification of sunflower oil. A maximum conversion (triglycerides to methyl esters) of 99.99% was achieved using the SG-KI/γ-Al2O3-770 catalyst under following optimal process parameters: 15:1 methanol to sunflower oil molar ratio, 2.5 wt% catalysts loading, 600 rpm stirring rate and 4 h of the reaction run.

AB  - Materials processing techniques, such as the combustion process, seem to hold much promise for the preparation of technologically important CoMoO4, owing to the control over stoichiometry, homogeneity and purity. Concerning the photocatalytic outness and powder characteristics, a glycine nitrate procedure (GNP) of CoMoO4 nanopowders by a glycine as a fuel and as a complexant was inspected. The synthesized samples were investigated by differential thermal analysis (DTA), Fourier transform infrared spectroscopy (FTIR), X-ray diffraction (XRD), Field emission scanning electron microscopy (FESEM), UltravioletVisible (UV/Vis) spectroscopy and nitrogen adsorption method. The glycine nitrate procedure (GNP) is simple, effective and suitable method for controlling the composition and morphology of CoMoO4. A single-phase α and β crystalline form of CoMoO4 compound was confirmed by DTA and X-ray diffraction (XRD). The obtained CoMoO4 nanopowder showed tendency of agglomeration, inhomogeneous microstructure and plate-like crystals. The photocatalytic activity of CoMoO4 nanopowders was assessment by the photocatalytic degradation of crystal violet in aqueous solution. In addition, the obtained specific CoMoO4 nanopowder demonstrated acceptable specific surface area, which can be of particular importance for the photocatalytic processes. The photocatalytic testing of CoMoO4 nanopowders showed that these nanostructured materials can be promising solutions in photocatalytic processes toward green chemistry and sustainable development.

AB  - In this research composite based on zirconia and graphite was synthesized using the sol-gel method. Aim of this research is to activate and increase the photocatalytic activity of ZrO2 by combining with graphite-based material. Our results show that we obtained material that can remove both cationic and anionic dyes by sorption and photocatalytic processes. Obtained composite is very effective in sorption of RB19 with up to 100% removal. Photocatalytic activity of composite is higher than pristine GO and goes up to 100% for RB19 degradation and about 50% degradation of MB. These results are promising and present an excellent base for further research. © 2022, Universitatea Babes-Bolyai, Catedra de Filosofie Sistematica. All rights reserved.

AB  - Silicon borides represent very appealing industrial materials for research owing to their remarkable features, and, together with other boride and carbide-based materials, have very wide applications. Various Si–B phases have been investigated in the past, however a limited number of studies have been done on the pristine SiB6 compound. Structure prediction using a data mining ab initio approach has been performed in pure silicon hexaboride. Several novel structures, for which there are no previous experimental or theoretical data, have been discovered. Each of the structure candidates were locally optimized on the DFT level, employing the LDA-PZ and the GGA-PBE functional. Mechanical and elastic properties for each of the predicted and experimentally observed modifications have been investigated in great detail. In particular, the ductility/brittleness relationship, the character of the bonding, Young’s modulus E, bulk modulus B, and shear modulus K, including anisotropy, have been calculated and analyzed.

AB  - In this paper, NiZnCo ferrite was produced by solid state synthesis, calcination at 1000 °C and sintering at 1250 °C in air atmosphere. The microstructure and phases of the sintered sample were analysed by scanning electron microscopy and X-ray diffraction, respectively. The magnetic properties of the ferrite were evaluated by magnetization and magnetostriction measurements. The complex magnetic permeability and complex permittivity were also measured between 1 MHz-12 GHz and the reflection loss (RL) was calculated in the 100 MHz-12 GHz frequency range. The results show that the ferrite sample presents magnetostrictive behaviour and a saturation magnetization of 71 Am2/kg. Complex permittivity measurements indicate that the material has dielectric behaviour in the whole frequency range studied, with ε′ varying between 7-40, and magnetic behaviour in frequencies between 1 MHz-5 GHz. The minimum RL was found at frequencies between 2.4-3.3 GHz and the calculated RL value for a thickness of 3 mm was lower than −10 dB in frequencies between 2.3-7.3 GHz. These results indicate potential application as microwave absorber in the S band.

AB  - Boron carbide (B4C) has attracted great attention as a semiconducting material with excellent properties and has found various technological applications. High hardness value makes it a potentially superhard material as well as a low density, high degree of chemical inertness, high melting temperature, thermal stability, abrasion resistance, and excellent neutron absorption, contributed to the use of boron carbide as an abrasive material for extreme conditions, wear resistance components, body armors and as a nuclear absorber or solid-state neutron detector. However, B4C is known for its unusual structure, bonding, and substitutional disordering whose nature is not yet fully understood, and exhibits brittle impact behavior. In this study we investigated the chain-model structure with an arrangement of 12-boron atom icosahedra and linear 3-carbon atom chains, using available experimental data. We employed the DFT method with LDA and GGA- PBE functional, as implemented in the CRYSTAL17 software package. Electronic properties of boron carbide have been investigated by calculating the density of states (DOS) and band structure. Calculated mechanical properties have been investigated: bulk modulus, shear modulus, Young modulus, Poisson’s ratio, hardness, and elastic tensor constants, and compared with available experimental data.

AB  - A visible-light-responsive hybrid material was prepared by surface-modification of γ-Al2O3, an insulator with a bandgap of about 8.7 eV, with 5-aminosalicylic acid (5-ASA), leading to the formation of an interfacial charge transfer (ICT) complex. The microstructural characterization of pristine γ-Al2O3 includes X-ray diffraction analysis, transmission electron microscopy, and nitrogen adsorption-desorption isotherms. The pristine γ-Al2O3 powder consists of agglomerated rod-like nanoparticles ((2-3) × (15-20) nm, diameter × length) with the large specific surface area (~420 m2/g). An enormous absorption red-shift is observed upon the formation of the ICT complex. The absorption onset of the inorganic-organic hybrid was found to be at 730 nm by diffuse reflection spectroscopy. The photocatalytic performance of prepared samples was thoroughly tested using the decolorization of the organic dye crystal violet (CV) under illumination in different spectral regions and different light intensities. Excitation with UV light leads to complete decolorization of CV, while the degradation kinetics are impeded when a visible light source is used. Also, the increase of UV light intensity induced significantly faster degradation kinetics of CV, while the degradation rates of CV are quite insensitive to the increase of visible light intensity.

AB  - A glassy carbon electrode was functionalized by MoO2 nanoparticle–decorated multiwalled carbon nanotubes (MWCNTs) and examined as a working electrode in oxyfluorfen (OXY) detection by differential pulse stripping voltammetry (DPSV). Measurement parameters were as follows: initial potential − 0.1 V, end potential + 0.5 V, accumulation potential − 0.15 V, accumulation time 80 s, and scan rate 50 mV s−1. A stripping potential of + 0.315 V vs. Ag/AgCl was employed. The pPesticide oxyfluorfen was determined in model samples by DPSV with good reproducibility (RSD <2.4%) in the concentration range 2.5 to 34.5 ng mL−1, with r = 0.99 and a limit of detection of 1.5 ng mL−1. These results are in the same range as those of HPLC/DAD, which is used as the comparative method. Recovery for OXY determination in a real river water sample was 102%. Analyses in Briton-Robinson buffer has shown to be pH dependent with the best response at pH 6.0. Structural characterization of MoO2-MWCNT by Raman spectroscopy, field emission scanning electron microscopy, high-resolution transmission electron microscopy, and X-ray crystallography revealed a preserved MWCNT structure decorated with firmly attached clusters of MoO2 nanoparticles.

AB  - The synthesis route by solution combustion, a glycine nitrate procedure (GNP) of CoMoO4 nanopowders by a glycine as a fuel and as a complexant was examined concerning the photocatalytic aspects and powder characteristics. The synthesized samples were investigated by differential thermal analysis (DTA), Fourier transform infrared spectroscopy (FTIR), X-ray diffraction (XRD), Field emission scanning electron microscopy (FESEM) and nitrogen adsorption method. In this work, we presented a simple and effective method for controlling the composition and morphology of CoMoO4. A single-phase α and β crystalline form of CoMoO4 compound was confirmed by X-ray diffraction (XRD). The photocatalytic testing of CoMoO4 nanopowders showed that these nanostructured materials can be promising solutions in photocatalytic processes toward green chemistry and sustainable development.

AB  - Three types of functional ceramic composites were designed, synthesized and probed for effective sulfide removal from aqueous solutions. The main goal was to examine complex influence of graphite, surpluses of Fe (similar to 4%) and micro-additions of Cu (similar to 0.2%) on the functional features of the composites. The structural, textural, morphological and surface characteristics of the composites were examined in detail by XRD, nitrogen sorption, SEM and FTIR. It has been shown that all composites are solid heterogeneous systems containing amorphous and crystalline phases (graphite, hematite, montmorillonite, quartz, etc.) with pronounced redox activity in contact with sulfide aqueous solutions. Great enhancment of sulfide consumption was detected for composites which contained graphite and it was established that reaction kinetics is fitted to irreversible second-order batch reaction with two reactants. After the treatment of 1 mM S2- solution, using composite dossage of 1 g/dm(3), concentration dropped down to 0.02 mM. In addition, cyclic voltammetry at 50 mV/s revealed the key role of dopants in electrochemical aspect of the process. Obvious boost of S2- uptake is ascribed to numerous electrochemical, chemical and sorption processes on the composite's developed surface.
