Summary: This study explores the potential of amorphous Ge anodes in multivalent-ion batteries and finds that compounds formed by Ge alloying with Mg and Ca exhibit higher capacities. Among them, the Mg-Ge system shows a smaller volume expansion ratio and higher ion diffusivity, which may be attributed to the coordination number of the Ge host atoms and the smaller atomic size of Mg.

Summary: Siligraphene, a combination of monolayer silicon and monolayer carbon, is a promising anode material for potassium ion batteries, with high stability, high capacity, fast ion diffusion, and excellent electrical conductivity. The theoretical capacity and average voltage of g-SiC5 and g-Si2C4 for KIB are 304.1 mA h/g and 128.6 mA h/g, about 0.4 V and 0.3 V respectively. NEB calculations show low energy barriers for potassium ion diffusion on siligraphene, indicating a high migration rate. Additionally, bandstructure calculations demonstrate excellent electrical conductivity after potassium ion absorption, and MD calculations confirm good stability of siligraphene with absorbed potassium ions.

Summary: This study reveals outstanding magnesium capacities for antimonene and an antimonene/graphene heterostructure through first-principles calculations. The most stable adsorption position for Mg atoms on the antimonene surface is directly above the center of the buckled honeycomb six-membered Sb ring. Mg ions diffuse more easily on the heterostructure surface compared to the antimonene monolayer, with a lower diffusion barrier.

Summary: Recent studies have shown that 2D materials, such as siloxene and germanane, can exhibit excellent performance as electrodes in alkali metal ion batteries. The improved electrochemical behavior of these materials is likely due to their limited volume change during charge and discharge, which is based on an intercalation mechanism rather than alloying. To combine the cheapness of Si and high electronic conductivity of Ge, we propose a new series of layered materials called siliganes, which are 2D Si-Ge composites. Among them, siligane_Si0.1Ge0.9 demonstrated the best electrochemical performance in Na- and K-ion batteries.

Summary: Compared to lithium metal, sodium resources on Earth are more abundant and evenly distributed, making sodium-ion batteries a potential replacement for lithium-ion batteries in large-scale energy storage systems. Hard carbon, among various anode materials, shows advantages and commercial potential for sodium-ion batteries. This review analyzes the adsorption behavior and discharge process of sodium ions on hard carbon, discusses the controversial storage mechanism, and summarizes four storage mechanisms. The relationships between morphology and structure regulation, heteroatom doping, and electrolyte optimization are further explored, as well as the electrochemical performance of hard carbon anodes. Sodium-ion batteries with hard carbon anodes are expected to have excellent electrochemical performance and lower costs for large-scale energy storage.

Summary: This study investigates the electronic properties and structural attributes of doped monolayer phosphorene using density functional theory (DFT). The chosen dopants (carbon, silicon, oxygen, and sulphur) induce a transition from semiconducting to metallic nature. All findings are supported by band structure, density of states (DOS), electron density, and electron difference density spectra. The study also explores the binding energy and concludes that the dopants' energy range (-6 eV to -10 eV) makes doping feasible. The lattice remains undistorted after doping, and the valence electronic configuration of the dopants imparts n-type and p-type characteristics to the phosphorene structure. The insights gained from this work provide a deeper understanding of the behavior and potential applications of doped phosphorene.

Summary: This study focuses on manganese doped CdS thin films synthesized by chemical bath deposition. The incorporation of Mn2+ cations in CdS was found to influence the crystalline structure, morphology, and optoelectronic properties. Doped thin films exhibited a uniform hexagonal structure, changed growth orientation, and showed scale-like and needle-like morphologies. The bandgap and rectification speed of Schottky diodes were modified by introducing manganese. This study suggests the potential for affordable high-speed optoelectronic devices.

Summary: This study focuses on the corrosion characteristics of AA 7075 and AA 7075 based hybrid composite fabricated using stir casting and hot rolling techniques. The results show that the hybrid composite produced by hot cross rolling exhibits better corrosion resistance compared to the base metal. The addition of a small amount of graphite improves the bonding between the matrix and reinforcements, and the hot cross rolling enhances this bonding, leading to the formation of a strong passivation oxide layer and increased charge transfer resistance, thereby improving corrosion resistance.
