Summary: Bismuth oxyhalides (BiOX, X = Cl, Br, and I) have attracted a lot of attention due to their unique layered structures, optical, and electronic properties. These bismuth-based photocatalysts have shown excellent efficiency in photocatalytic activities such as pollutant removal, water splitting, antibacterial activity, and sensor studies under visible light irradiation. However, their practical application is limited by their band structures and fast recombination of electron-hole pairs. Various modifications, such as doping and heterojunction design, have been explored to enhance their photocatalytic performance under visible light. This review summarizes the synthesis methods, modifications, and applications of bismuth oxyhalides in photocatalysis, hydrogen production, antibacterial studies, and sensing properties.

Fe3O4/BiOI p-n heterojunctions were constructed and characterized for this purpose. The degradation process of RhB by Fe3O4/BiOI heterojunction under visible light followed a pseudo-first-order kinetic model. The mechanism of photocatalytic peroxydisulfate activation over Fe3O4/BiOI heterojunction was proposed and discussed.

Summary: A Bismuth-based photocatalytic material, BiOCl/Bi3NbO7, was fabricated through an in situ growth method, and showed promising potential in degrading contaminants in water. The study investigated the effect of different molar ratios of Bi and Nb elements on the material's structure and photoelectric characteristics, and found that an appropriate ratio could enhance the photocatalytic activity by reducing interface resistance. The degradation mechanism of RhB was also proposed, with •OH and •O2- identified as the main active species.

Summary: In recent years, polymer-based nanocomposites have been extensively studied and utilized in tissue engineering for bone regeneration. These biodegradable nanocomposites have shown advantages in bone tissue cultivation and production. While some polymeric materials used in bone tissue engineering are biodegradable and bioactive, they often lack the required strength. Conversely, metallic implants are mechanically strong but pose risks of infection and secondary surgery. Polymer nanocomposites, on the other hand, possess bioinertness, low chemical reactivity, and the capability to mimic bone characteristics for orthopedic applications, offering potential solutions for bone abnormalities.

Summary: Due to the scarcity and lack of biodegradability of petroleum-based polymers, researchers are looking for green biopolymers as an alternative in the automobile and aviation industries. While automakers have successfully used bio-based materials in newer automobiles, the use of biopolymers in aviation is limited due to stricter property requirements. Advanced biopolymers are applied in various aircraft components, and these materials are expected to substitute traditional plastics with the help of modifying agents and cutting-edge manufacturing technology.

Summary: In this paper, high-resolution computed tomography (micro-CT) was used to visualize the inner structure of lithium nickel cobalt aluminum oxide 18 650 form-factor batteries non-destructively after and during a heat endurance test. Open circuit relaxation and electrochemical impedance spectroscopy were also conducted. The study found that drastic changes in the structure of the battery at higher temperatures are traceable. Layer delamination and performance loss were observed at 150 degrees C, and battery failure occurred with further temperature increase. Precipitation and fracture of the positive temperature coefficient device were also observed. Only tomographic methods can provide insight into the inner structure of the battery without opening it. Measurement of changes in layer distances and decent shrinkage were observed, which can be linked to the loss of capacity and increased resistance.

Summary: The use of rare nickel-poor and aluminum-rich layered double hydroxides (LDHs) as catalyst precursors in CO2 hydrogenations highlights the importance of the chemical quality of the interlayer anions. The thermal stability and chemical properties of the anions significantly affect the reaction outcomes. The choice and removal of the anions result in differences in LDH transformation, reducibility of Ni(II), and specific surface area of the resulting metal oxides. Furthermore, the conversion and selectivity are correlated with the abundance and strength of base and acid sites in the LDHs.
