Summary: Considering a commercial aluminosilicate glass as an example, the correlations between different heat treatments and the characteristics of chemical strengthening are investigated. The results show that pre-heating treatment has an influential effect on chemical strengthening, increasing the generated compressive stress by about 10%, while the depth of the compressive layer remains the same regardless of heat treatment. These behaviors can be connected to structural evolutions observed through a Raman analysis, indicating that densification of the glass structure on a medium range scale influences the stuffing effect of chemical strengthening. Additionally, the stress profile of aluminosilicate glasses can be engineered via heat-treatment before the ionic exchange process.

Summary: Sodium alumino-silicate (SAS) glasses were synthesized with varying P2O5 and B2O3 contents to investigate their effects on chemical strengthening properties. Replacing SiO2 with P2O5 decreased surface compressive stress (CS) but increased depth of layer (DOL), while B2O3 improved CS at the expense of DOL.

Summary: In this study, the influence of chemical strengthening residual stress on the flexural strength and fracture behavior of aluminosilicate glass was investigated using a combination of experimental, theoretical, and numerical approaches. It was found that the mechanical strength of chemically strengthened glass is closely related to the depth of the chemical strengthening layer and surface flaw depth. The proposed finite element numerical method was able to accurately replicate the mechanical strength and failure modes of both annealed and chemically strengthened glass, demonstrating the effectiveness of the approach in representing the discrete fracture behavior and strengthening effect of silicate glass.

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.
