Summary: In this paper, a novel cathode material, quinone functionalized hexahydroxytriphenylene (HHTP) and diphenylbutadiynebis (boronic acid) (DPB) based porous polymer (QHHTP-DPB), is suggested for magnesium-ion batteries (MIBs). The material exhibits a stable and highly porous structure with strong affinities for magnesium ions. Theoretical calculations indicate that the polymer can achieve a high theoretical capacity of 720.48 mAh/g and a positive low open-circuit voltage of 0.39 V. The results suggest that the designed quinone functionalized HHTP-DPB porous polymer could be a potential cathode material for MIBs.

Summary: Rechargeable magnesium batteries (RMBs) are promising for their potential in high energy density, low cost, and high safety. However, technological breakthroughs are required for commercialization. Cathode materials are crucial for the commercialization of RMBs as they directly affect energy and power densities. The main challenge lies in the poor diffusion of Mg2+ ions in electrode materials due to strong interaction with host materials. Various attempts have been made to overcome this issue, including synthesis of new materials, morphological modifications, doping, substitution, and addition of second components. This review provides additional information on recent developments in cathode materials for RMBs in the past 3-4 years, as well as perspectives and challenges for future development.

Summary: Chemical solution deposition is a versatile method for fabricating oxide films. The BaTiO3 films prepared on different SrTiO3 substrates were shown to be epitaxial and under tensile strain due to the difference in thermal expansion between the materials. Despite imperfections like edge dislocations and Ba-deficient boundaries, the films still exhibit excellent ferroelectric properties.

Summary: In this study, both undoped and gallium-doped TiO2 nanoparticles were synthesized using the sol-gel method, followed by X-ray diffraction and density functional theory analysis to study their crystallographic properties and electronic structures. The effect of gallium doping on the bandgap of TiO2 was investigated, showing an increase at 6.25% doping and a decrease at 12.5% doping. This research suggests potential applications of gallium-doped TiO2 in electron transport layers and other photoelectric cell fields.

Summary: In this study, carbon nanotube forests were directly grown on basalt fabrics using a chemical vapor deposition process. The growth of nanotubes on basalt fibers was found to be catalyzed by the microstructural segregation of ferrous iron and its subsequent reduction in a hydrogen atmosphere. A pre-treatment etching was found to be necessary for in situ growth.

Summary: The microstructure and tensile properties of a hot work tool steel manufactured via laser powder bed fusion (LPBF) were studied. Two different orientations and two quenching and tempering heat treatments were applied. Microstructural analysis showed a homogenous tempered martensite structure after both heat treatments, with the presence of higher alloying segregation in samples subjected to higher tempering temperatures. Building orientation had negligible effect on mechanical properties, while heat treatment parameters had significant influence. The treatment with lower tempering temperatures and a sub-zero step resulted in higher hardness, tensile strength, and elongation.
