Summary: The electrochemical Li/Na/K-ion reaction pathways in Ga for high-performance Ga anodes in alkali-ion batteries are thoroughly elucidated using ex situ analytical tools. Ga exhibits a high Li-ion storage reaction, forming Li2Ga, but poor Na- and K-ion storage reactions, forming NaGa4 and K3Ga13, respectively. An amorphous Ga composite (Ga/C) is fabricated, showing high reversible capacity, long-term Li-ion storage stability, and high rate capability. Three-step confinement of amorphous Ga in the composite during cycling is demonstrated as an enhancement mechanism for high-performance Ga/C anodes for LIBs.

Summary: Hard carbons, as a category of non-graphitizable amorphous carbons, are considered the most promising anode materials for emerging sodium-ion batteries due to their changeable low-potential charge/discharge plateaus. This review revisits the definitions and structural models of hard carbons and presents a renewed understanding of their sodium storage. Three critical structural features, namely crystallites, defects, and nanopores, are highlighted for their impact on sodium storage. The review proposes sieving carbons as an ideal configuration for high-capacity carbon anodes, aiming to facilitate the industrialization of sodium-ion batteries and explore new potential uses.

Summary: High-quality and partially oriented ZnO nanorod films were synthesized by chemical bath deposition on ZnO sol-gel spin-coating seed layer. The films showed wurtzite structure with a crystallite size of about 50-55 nm, and exhibited oxygen vacancies and a bandgap energy of approximately 3.24 eV. The electronic conductivity showed temperature-dependent behavior and obeyed the grain boundary carrier-trapping model with an activation energy close to 0.6 eV, attributed to chemisorption of oxygen at the grain boundaries.

Summary: The g-C3N4/NiS photocatalyst was synthesized using a two-step procedure involving thermal condensation and solvothermal techniques, leading to the observation of two phases in the hybrid material obtained. UV spectroscopy analysis revealed a shift to lower energies in the adsorption region compared to bare g-C3N4, with corresponding band gap values of 2.74 and 2.3 eV. SEM analysis showed the typical g-C3N4 lamellar morphology with NiS clusters grown over it, while the yield of H-2 obtained in the water splitting reaction under UV irradiation was 30% higher than that obtained when pure g-C3N4 was used as the photocatalyst.

Summary: This study presents a comprehensive investigation into the structural changes and photocatalytic properties of cerium-doped anatase. It is found that the doping of cerium can modify the structure and photocatalytic properties of anatase, with the effect varying with annealing temperature. The changes in photocatalytic properties are validated by molecular softness and the mineralization of 2,4-Dichlorophenoxyacetic acid, with the mineralization greatly improved as a function of molecular softness. Computational chemistry calculations suggest that the electrophilic attack from cerium-doped anatase to chlorine atoms of 2,4-D in an aqueous system may initiate the mineralization process. The stability of TICE-III materials as photocatalysts after 4 cycles was also tested.

Summary: This study presents an innovative approach to improve the photovoltaic conversion characteristics and stability of perovskite solar cells through carbon electrode interface modification. By in-situ polymerization and carbonization on the surface of nano-graphite, a dendritic structure carbon electrode is formed, reducing the work function and aligning the energy levels with perovskite. This leads to improved charge and hole collection efficiency, resulting in increased photovoltaic conversion efficiency. Furthermore, the modified carbon electrode-based perovskite solar cells exhibit exceptional stability, maintaining high efficiency even without encapsulation.

Summary: This study demonstrates the improvement of mechanical properties and reduction of coefficient of thermal expansion (CTE) in graphene oxide (GO)/epoxy (EP) nanocomposites by enhancing the interface between GO and EP through functionalization and incorporating rigid-flexible interphases. The results reveal that the SiO2-PEA-GO hybrid exhibits better strengthening and toughening effects, as well as lower CTE, compared to the PEA-GO hybrid due to the presence of rigid-flexible interfaces with higher bonding strength and better energy dissipation mechanisms. Additionally, the nanocomposites with longer polyetheramine (PEA) molecules in the rigid-flexible interphases demonstrate higher strength and toughness, while maintaining a lower CTE. This work provides a promising strategy for constructing adjustable flexible-rigid interfacial structures and offers potential in developing GO/EP nanocomposites with high mechanical properties and low CTE.
