Summary: The aim of this study is to investigate the influence of solvents used in the sol-gel process and supercritical drying on the properties of NiO aerogels. It was found that the specific surface area, phase, and chemical composition strongly depend on the synthesis conditions. Using 2-methoxy-ethanol as a solvent can reduce Ni2+ to Ni-0.

Summary: NiOx, Li:NiOx, and Li,Mg:NiOx powders were produced by sol-gel method, and their structural and optical properties were studied. XPS results confirmed the successful incorporation of Li+ and Mg2+ into NiOx structure, with decreased crystallite size as dopant concentration increased. Addition of Li+ and Mg2+ led to reduced emission intensity and average decay time compared to pristine NiOx.

Summary: In this study, a biocatalytic glucose optical sensor was developed by immobilizing glucose oxidase (GOD) on a polymethylmethacrylate (PMMA) optical fiber. The enzyme encapsulation process was carried out using the sol-gel method, with a TEOS-based coating deposited on the fiber end by immersion. The sensor was characterized using different glucose levels. The optimal enzyme encapsulation process was found to be performed at room temperature, followed by the deposition of the coating on the fiber. The drying process showed optimal results at temperatures below 8°C.

Summary: Metal aerogels (MAs) are a new class of porous materials consisting of nanostructured metals. They possess unique physicochemical properties and show great potential in various fields such as electrocatalysis and sensing. However, due to their short research history, fundamental studies and practical applications of MAs are still limited. Challenges include controlled synthesis, structural diversity, and the correlation between material parameters and properties. Thorough knowledge and design principles of MAs are crucial for further development in this promising field.

Summary: This study reports the synthesis of Sr0.9M0.1RuO3-delta (SMRO, M=K, Na, Ag) perovskite catalysts via a sol-gel method, which exhibit excellent oxygen evolution and oxygen reduction reaction performance. Metal ion doping introduces oxygen vacancies and lattice oxygen into the structure, which is identified as the main reason for the improved catalytic activity. Among the four samples, Sr0.9Ag0.1RuO3 (SARO) shows the highest activity. This work may offer insights into the design of efficient bifunctional OER/ORR electrocatalysts.

Summary: The study investigates the effects of Cr and N doping on the properties of TiO2 anatase nanoparticles, including adsorption capacity, photocatalytic performance, and antibacterial response. Doping with Cr and Cr/N enhances adsorption capacity and photocatalytic performance, with Cr-TiO2 nanoparticles exhibiting antibacterial activity under visible light. The differences in electrostatic charge and nanoparticle dispersion are suggested as the main reasons for the varied antibacterial response among the doped nanoparticles.

Summary: In the power-to-gas scenario, surplus renewable electricity is stored in the form of methane by reacting green hydrogen with waste CO2. Low-cost catalysts with high activity at low temperature are necessary. This study introduces the sol-gel preparation of high-loading mesoporous Ni/SiO2 catalysts. Characterization techniques show that small Ni particles are obtained, even at high loading. The catalyst with the best performance achieved a specific activity almost three times higher than a reference catalyst prepared by impregnation.

Summary: This study investigates the influence of the flexible spacer parity of a guest photoactive liquid crystalline dimer on the photonic bandgap features of the cholesteric and twist grain boundary smectic C phases of the host molecule. The results show that the parity of the photoactive dimer affects the width of the photonic bandgap and the blue-shift of the cholesteric phase. Additionally, the parity of the dimer also affects the layer spacing and two-dimensional periodicity of the liquid crystalline phases.

Summary: This work focuses on the thermochemistry of solvation of azeotropes. The enthalpies of dissolution of azeotropes in different mediums were determined, and the impact of the structure of the azeotropes on their properties in solution was discussed. A correlation between enthalpies of solvation and molar refraction was used to determine the vaporization enthalpies of azeotropes for the first time. The results were found to be consistent with literature data, obtained using direct and calculated methods. These findings contribute to the analysis of the structure-property relationships of azeotropes.

In this study, we experimentally and theoretically investigated an Al-Cu-Co system within different composition ranges, and identified high-temperature solid phases. Our findings demonstrated the correlation between the boundaries of different solid phases and undercooling and viscosity in the concentration area.

Summary: In this study, the interactions between doped and pristine coronenes and adenine nucleobases were investigated using Density Functional Theory. The optimal configurations, adsorption energies, charge transfer, and electrical properties of each complex were calculated. It was found that doped coronene had stronger adsorption strength and charge transfer compared to pristine coronene. The stability of the complexes was attributed to non-covalent interactions in the interactive region. The change in electrical conductivity of coronenes after adsorption suggested their sensitivity towards DNA bases. The predicted energy gap and prolonged recovery time for adenine-coronene configurations indicated the potential application of pristine/doped coronene in DNA detection.

Summary: This study investigates the effects of different transition metal decorations on B12N12 nanocages on the adsorption properties of nitrosourea drugs using computational methods. The results reveal the presence of weak non-covalent interactions between metals and nanocages, and the interaction between drugs and nanocages plays a significant role in drug adsorption. Compared to free drugs, the adsorption of drugs on nanocages can facilitate electron transfer, reduce energy gaps and chemical hardness, indicating activity at the target site.

Summary: In this study, the selective oxidation of aromatic aldehydes was investigated using Ru(VI) as a catalyst and hexacyanoferrate (III) as a cooxidant in an alkaline medium. The reaction mechanism involves complex reaction orders for the oxidant and the aromatic aldehyde, while the reaction order for Ru(VI) is one. The proposed mechanism includes two catalytic cycles and the formation and decomposition of complexes. Quantitative structure-activity relationship analysis showed that deactivating groups in the para-position enhance the process.

Summary: This study evaluated the adsorption of zolpidem on magnetic graphene oxide and synthesized magnetic graphene oxide adsorbents for zolpidem removal. The best magnetic nanoadsorbent was found to have a removal percentage of 87.07% at specific pH and temperature conditions. The results suggest that the removal of zolpidem is related to the surface chemistry of the adsorbent rather than the surface area of graphene oxide. The adsorbent showed excellent adsorption efficiency and magnetic behavior, making it a promising material for removing zolpidem from aqueous solutions.

Summary: This study examines the sensitivity of the thermal conductivity of water-based alumina nanofluids to changes in concentration, sphericity, and temperature. The results show that volume fraction and temperature have a significant impact on the thermal conductivity, while sphericity also needs to be considered. A support vector machine regression model was created to analyze the sensitivity of the thermal conductivity to different parameters. The findings indicate that temperature, sphericity, and volume fraction are the most sensitive variables.

Summary: This paper reports on the synthesis, structural characterization, spectral and nonlinear-optical properties of glass nanocomposites made of glass forming ionic liquid crystals and nanoparticles. The study reveals that by exciting the nanocomposites within their absorption band, a control over effective optical nonlinearities can be achieved, allowing the modification of the magnitude and sign of the effective nonlinear absorption coefficient. The proposed strategy using metal-alkanoates based glass-forming ionic liquid crystals and nanoparticles shows great potential for the development of nanophotonics and plasmonics technologies.
