Summary: Developing a new strategy to prevent the restacking of MXene nanosheets is crucial for designing flexible supercapacitor electrodes. In this study, a novel Ti3C2Tx/PVA porous sponge was prepared and used as a template for in-situ PANI polymerization. The resulting PANI@Ti3C2Tx/PVA hydrogel composite exhibited both double-layer capacitance and pseudocapacitance behavior, and demonstrated excellent capacitance, energy density, and power density. The capacitance of this supercapacitor remained almost unchanged under different bending angles, and showed 99% capacitance retention after 10,000 charge/discharge cycles.

Summary: In this study, NiO films with different Al doping ratios were deposited on glass and n-type Si substrates using the sol-gel process. The physical and electrical characterizations of the films were investigated, with a focus on the effect of Al doping. The results showed that increasing Al doping resulted in a decrease in crystallinity and an increase in band gap. X-ray photoelectron spectroscopy analysis revealed the presence of both Ni+2 and Ni+3 ions in the undoped NiO lattice, with Ni+2 being reduced due to Al+3 substitution. The heterojunction photodiodes based on NiO films showed good rectifying properties, with ideality factor and barrier height decreasing and rectification ratios increasing with increasing Al doping. The photosensitivity increased but photoresponse decreased with increasing Al doping.

Summary: The aim of this research was to develop a new, low-cost, and low-energy-consuming method for preparing highly porous silica systems. The precursor gel systems were synthesized using sol-gel chemistry with TEOS and water glass. The impact of the chemical composition, catalysts, pH, and additives on the structure and porosity of the cryogels was investigated. The gel systems were subjected to freeze-drying to obtain porous cryogel silica products with hierarchical structures. The freeze-drying process conditions were also studied to increase the porosity. Small angle X-ray measurements, scanning electron microscopy, and infrared spectroscopy were used to study the gel and cryogel systems.

Summary: In this study, titanium dioxide scaffolds were successfully synthesized using the sol-gel method. The scaffolds were formed by using titanium isopropoxide as a precursor and a polymeric network of galactopyranose as a template. The synthesized scaffolds have diameters of 50 nm and porosity ranging from 0.3 to 10 nm. XRD analysis confirmed the formation of crystalline phases in the TiO2 scaffold at 700 degrees C. The use of biological polymers as templates provides a low-cost and efficient approach for the synthesis of new materials.

Summary: In this research, a polyvinyl alcohol (PVA) modified Al sol is applied to an AlSl304 steel to protect it from oxidation etching in air at 900°C. The coated sample shows better oxidation resistance compared to the substrate, as indicated by a decrease in mass gain. The resulting oxide layer is dense, continuous, and does not flake, effectively preventing inward diffusion of oxygen atoms. By using the PVA-Al sol film, beneficial anti-oxidation (Cr, Al)2O3 and Fe3O4 phases are formed, while the detrimental Fe-rich hematite phase is avoided.

Summary: Bi2212 high-temperature superconducting thin films (HTSFs) were prepared on SrTiO3 (100) substrates using metal nitrates as raw materials and the Pechini sol-gel method. EDTA and PVA were employed to improve the dissolution characteristics of Bi2212 solution. The effects of various parameters on film properties were systematically investigated, and it was found that a higher concentration of PVA led to reduced solubility of the Bi2212 solution. Notably, a 1% concentration of PVA resulted in exceptional epitaxial properties, enhanced Bi2212 phase purity, reduced surface roughness, and higher Tc for the fabricated Bi2212 thin film.

Summary: The effects of process parameters on the nonhydrolytic sol-gel synthesis of Ba0.6Sr0.4TiO3 were systematically studied. The results showed that the coarse concentration had a significant impact on the synthesis rate, while the fine concentration had no obvious effect on low-temperature synthesis. By adjusting the Ba-Sr-Ti mole ratio, the impurity phase BaCO3 caused by titanium source volatilization could be effectively eliminated. The optimized process parameters allowed for the synthesis of pure phase Ba0.6Sr0.4TiO3 at a low temperature of 600°C, with a particle size of 17-43 nm and a mono-crystalline structure.

Summary: The Spark Plasma Sintering (SPS) process was used to synthesize Ba0.5Sr0.5TiO3-Mg2SiO4-MgO composite, and the effect of the sintering method on the dielectric properties of the samples was systematically investigated. The experiment results show that the composite exhibits higher tunability and lower permittivity compared to undoped Ba0.5Sr0.5TiO3. The improved tunability is mainly attributed to the low sintering temperature and short sintering time in SPS, which effectively suppress the doping effects.

Summary: In this study, a CO2 sensor capable of low-temperature operation was fabricated using an open-channel-type thin-film transistor structure with a polar surface of an oxide semiconductor. The sensor showed a sensitivity 2.9 times greater than that under an inert N2 atmosphere at an operating temperature of only 150 degrees C. The results suggest that TFTs fabricated with polar surfaces of oxide semiconductors are useful for gas-sensing applications.

Summary: A variety of hierarchical nanoporous silica aerogels were synthesized from well-dispersed silica sols, exhibiting diversified particle distributions and excellent thermal properties. The silica aerogels showed low thermal conductivity and high-temperature resilience. Surface modification and dilution of silica sols further improved the thermal resistance of the aerogels. The resilient skeleton structure developed from tiny particles effectively restricted heat dissipation and maintained the porous network at high temperatures.

Summary: In this study, a defective system of V-doped Fe2O3 with Pt as a cocatalyst was used for photoelectrochemical water oxidation. The defects in the VFPt-2.5 photoanode were characterized by XPS and EPR analyses. The SEM and TEM analyses revealed that the electrodeposited V-doped alpha-Fe2O3 had a nanosized morphology with an average diameter of 12 nm and a thickness of 300 nm. Under light irradiation, the VFPt-2.5 photoanode achieved a remarkable onset potential and photocurrent density. The stability test showed that Pt helped overcome the charge recombination caused by surface states.
