Summary: A proteic sol-gel route using edible gelatin as a precursor was employed to produce NiMoO4 catalysts. The catalysts were characterized using various techniques, and phase-pure alpha-NiMoO4 polymorph was obtained at temperatures above 700 degrees C. The catalyst calcined at 700 degrees C exhibited the highest stability, activity, and best selectivity in the ethanol steam reforming reaction for hydrogen production.

Summary: In this study, LaFeO3 film prepared by the sol-gel method was used to catalytically plasma nitride 38CrMoAl steel. Plasma nitriding treatments were conducted at 520 degrees C for different durations. The effects of LaFeO3 on the microstructure, phase structure, mechanical, and tribological properties of the plasma nitrided layers were investigated. The results showed that LaFeO3 was effective in accelerating the plasma nitriding process and improving the surface properties of the nitrided layers.

Summary: Monometallic and bimetallic catalysts based on Fe, Ni, and Pd were synthesized and tested for chlorobenzene hydrodechlorination. The sol-gel cogelation process resulted in small metallic nanoparticles dispersed within the silica matrix. The Pd-Ni catalysts showed lower activity than monometallic Pd catalysts, but increasing the Ni content led to amplified catalyst deactivation. In contrast, Pd-Fe catalysts exhibited higher activity due to the presence of Fe-Pd alloy. Fe had a cooperative effect when coupled with Pd, reducing Pd poisoning by HCl.

Summary: This study used the peroxovanadate sol-gel method to produce ZnO-doped V2O5 thin films and investigated the effect of doping on the electrochromic and structural characteristics of the films. The results showed that ZnO doping improved the cyclic stability and reversibility of the films, making them promising candidates for electrochromic device applications.

Summary: In this study, spinel-type MgCr2O4 nanoparticles were synthesized using a sol-gel auto-combustion method with fructose, tartaric acid, and hexamethylenetetramine as chelating/fuel agents. The formation of impurity-free MgCr2O4 nanostructures was optimal at temperatures ranging from 500 to 750 degrees C. Characterization techniques such as FTIR, UV-VIS spectrophotometry, XRD, EDX, and FE-SEM were used to study the properties of the synthesized nanoparticles, revealing the importance of the chelating/fuel agent nature and energy release during auto-combustion on the final properties of MgCr2O4 nanoparticles.

Summary: Perovskite-type catalysts with different doping amounts of B-site doped nickel were synthesized and their effects on crystal structure and catalytic performance were investigated. It was found that nickel doping caused lattice distortion and Ni-Fe alloy interactions, significantly affecting the morphology and catalytic activity of perovskite. The addition of LaNi0.6Fe0.4O3 (NI6) with a mass fraction of 5% resulted in the highest average burning rate of JF coal.

Summary: In this study, one-dimensional titania-based nanofilaments were synthesized via a hydrothermal method. It was found that regardless of the precursor materials and processing conditions, these nanofilaments served as the essential building blocks in all microstructures. This discovery is of significant importance for understanding and controlling the self-assembly process of nanomaterials.

Summary: The authors present a novel method of synthesizing fibers using the sol-gel process. They successfully prepared TiOx fibers using titanium ethylate as the precursor and lactic acid as a chelating ligand, and further processed the fibers into non-woven fleece. The study reveals a correlation between the lactic acid content and the dissolution behavior of the fibers. In vitro cell culture experiments demonstrated the potential suitability of the material as an open-mesh structured scaffold, even for advanced therapeutic medicinal products.

Summary: In this study, commercial cellulase was immobilized using sol-gel entrapment technique with the addition of magnetic nanoparticles. The catalytic efficiency of the immobilized cellulase was enhanced by tailoring the sol-gel matrix. Various characterization methods were used to analyze the properties of the nanobiocatalysts. The immobilized cellulase showed superior catalytic performance compared to the native enzyme, and promising results were obtained for scaling-up the process.

Summary: 10 wt% Ni/La2O3 catalysts for dry reforming of methane were synthesized by wetness impregnation of lanthana supports prepared using sol-gel citric method with and without NH3 addition. The Ni-La CA catalyst showed higher catalytic activity at 650 degrees Celsius, while Ni-La CA-NH3 exhibited higher stability under the same temperature and time conditions. After long run tests, both catalysts formed La2O2CO3 phase, but Ni-La CA showed more severe deactivation.
