Summary: The microstructural effects of a Cr-modified Ti-6Al-4V alloy on its mechanical, electrochemical and stress corrosion cracking properties were studied. The alloy showed enhanced mechanical properties and good corrosion resistance due to the refined microstructure and the formation of Cr2O3 oxide film. The alloy also exhibited decreased susceptibility to stress corrosion cracking at higher temperatures.

Summary: This study found that the susceptibility to hydrogen embrittlement (HE) differs significantly between Ti?6Al?4V alloys prepared by selective laser melting (SLM) and electron beam melting (EBM). The degradation of SLM Ti?6Al?4V in a hydrogen containing environment is likely to occur through hydride formation and cleavage mechanism, while Ti?6Al?4V prepared by EBM is more likely to degrade through hydrogen enhanced localized plasticity (HELP) mechanism.

Summary: This study investigates the use of TiNbTa and TiNbTaZr films as protective coatings on a Ti-6Al-4V alloy. The results show that films with high Ti and Zr contents exhibit inferior corrosion resistance compared to films with high Ta and Nb contents. The research also found that TiNbTa(Zr) films can effectively prevent the elution of Al and V from the Ti-6Al-4V alloy, making them potential candidates for biocompatible materials.

Summary: Utilizing the Gleeble-1500D thermal simulation machine, a study conducted isothermal compression tests on the Ti-6Al-4V titanium alloy at various deformation conditions. The results indicated that the BP-ANN model had higher accuracy compared to the Arrhenius model, with a correlation coefficient of 0.99959 and an average absolute relative error of 3.0935%. The titanium alloy model was able to predict flow stress in all deformation ranges, compensating for the lack of accuracy in the constitutive model.

Summary: The study finds that 3D-printed samples manufactured via SLM and EBM exhibit poor corrosion resistance compared to samples manufactured via ISF. The superior corrosion resistance of ISF-manufactured samples is attributed to the presence of a higher amount of beta phase and lower fraction of phase interfaces in the equiaxed alpha + beta microstructure.

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: Water is essential for the survival of living organisms, but industrialization has led to contamination of water sources with heavy metals and harmful pollutants. Magnetic nano ferrites have shown potential in effectively removing heavy metals from water due to their magnetic characteristics, high surface area, surface active sites, chemical stability, and ease of modification. This review explores recent literature on the synthesis and application of magnetic ferrites for removing heavy metals from water, aiming to provide a comprehensive understanding for future research.

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.
