Summary: This study investigates the structural features and hydrogenation mechanisms of Li4BN3H10 and Rh4BN3H10 alkali metal hydrides using first-principles calculations. The results show that Li4BN3H10 and Rh4BN3H10 are thermodynamically and dynamically stable. The hydrogen storage mechanism of AM4BN3H10 hydride relies on the formation of [BH4] and [NH2] groups. The hybridization between B and H atoms in [BH4] and N and H atoms in [NH2] enables efficient hydrogen storage. Rb4BN3H10 exhibits better hydrogen release properties compared to Li4BN3H10 and Na4BN3H10 due to its narrower band gap. Overall, AM4BN3H10 hydride is a promising hydrogen storage material with high capacity.

Summary: Based on density functional theory calculations, the feasibility of using a two-dimensional beta-GeS monolayer as a high-performance anode for alkali metal ion batteries was investigated. The results showed that the electrical conductivity of the beta-GeS monolayer could be enhanced by adsorbing alkali metal atoms, leading to a semiconductor-to-metal transition. The low diffusion barriers of alkali metal atoms on the beta-GeS surface indicated a rapid charge/discharge rate without metal clustering. Moreover, the beta-GeS monolayer exhibited a low average open-circuit voltage and a high theoretical capacity for Na, making it a promising anode material for high-performance Na-ion batteries.

Summary: Hydrogen has the potential to be a green energy source for cars, but the lack of effective hydrogen storage materials is a major obstacle. This study explores the hydrogen storage capacity and reversibility of the Ti-functionalized metal carbyne framework (MCF) with carbyne as an organic linker and Mg4O as an inorganic moiety. The Ti-functionalized MCF can adsorb up to five H-2 molecules per Ti atom with adsorption energy within the range specified by the DOE. The proposed Ti-functionalized MCF shows high gravimetric density and reversibility, making it a potential hydrogen storage medium meeting DOE standards.

Summary: In this work, we demonstrate the phase-controlled growth of SnS nanostructures by physical vapor deposition on mica substrates. The phase transition from a-SnS nanosheets to fi-SnS nanowires can be achieved by reducing the growth temperature and precursor concentration, which is attributed to the competition between SnS-mica interfacial coupling and phase cohesive energy. The resulting fi-SnS devices exhibit improved ambient stability, a reduced band gap, and enhanced optoelectronic properties compared to a-SnS devices.

Summary: In the literature, Zn-Mn aqueous batteries (ZMABs) exhibit abnormal capacity behavior and various charge/discharge behaviors due to electrolyte additive-induced complexes. However, the current performance assessment for ZMABs remains unregulated and lacks a comprehensive and impartial evaluation protocol. This hinders further research and commercialization. Therefore, a pH clue (proton-coupled reaction) is proposed to understand different mechanisms, and performance metrics including rated capacity (C-r) and electrolyte contribution ratio from Mn2+ (CfM) are discussed. Moreover, the relationship between Mn (II) <-> Mn (III) <-> Mn (IV) conversion chemistry and protons consumption/production is established, and the design concepts of a tunable H+/Zn2+/Mn2+ storage system for customized application scenarios are proposed, paving the way for the next-generation high-safety and reliable energy storage system.

Summary: The poor thermodynamic stability and sluggish electrochemical kinetics of metallic Zn anode in aqueous solution restrict its practical application. To overcome these problems, zincophilic surface modification strategies have been developed. However, there is still a lack of understanding regarding the selection of zincophilic sites based on the metrics of thermodynamics inertia and kinetics zincophilia. In this study, hetero-metallic interfaces are optimized to prioritize the Bi@Zn interface, which exhibits high efficiency due to its thermodynamics inertia and kinetics zincophilia. A practical metric for prioritizing zincophilic sites is proposed, and the Bi@Zn anode shows excellent performance in terms of low overpotential and stable cycle life.

Summary: MXenes are a new family of two-dimensional transition metal carbides and nitrides. Previous studies mainly focused on metallic MXenes, with few studies on semiconducting MXenes. By using first-principles calculations, researchers screened 480 different ground-state structures of MXenes, including 444 metals and 36 semiconductors. It was found that the bandgap, carrier mobility, and optical absorption of semiconducting MXenes strongly depend on the surface functional groups. By tuning the surface functional groups, the bandgaps of semiconducting MXenes can be varied from 0.2 to 3 eV. The semiconducting MXenes also exhibited high carrier mobilities up to 10(4) cm(2 )v(-1)s(-1) and high optical absorption coefficients (>10(5) cm(-1)). This study demonstrates the potential of Sc-based and Y-based MXenes for applications in electronics, optoelectronics, and photocatalysis.

Summary: Metal-organic framework (MOF) compounds form highly ordered periodic porous networks by connecting metal ions or clusters with organic ligands. With high porosity, large surface area, and controllable pore size, MOFs are widely used in gas storage, catalysis, adsorption, and separation. Incorporating MOFs into SERS substrates improves sensitivity and prevents aggregation of nanoparticles. This review discusses three methods of preparing MOF-based SERS substrates and explores their applications in biosensing, environment, gases, and medical treatments. The current status and prospects of MOF-based SERS analysis are summarized.

Summary: This study reports a new class of vdW metal-semiconductor junctions (MSJs) entirely composed of atomically thin MXenes. Through high-throughput first-principles calculations, 80 stable metals and 13 stable semiconductors are screened from 2256 MXene structures. The selected MXenes cover a broad range of work functions and bandgaps, providing a versatile material platform for constructing all-MXene vdW MSJs. The formation of all-MXene vdW MSJs leads to interfacial polarization, resulting in the deviation of Schottky barrier heights from the prediction of Schottky-Mott rule.

Summary: This study investigates the relationship between the morphology of PMMA monopolymers and PMMA-PHEMA copolymers with the expected nature of surfactant-free microemulsions (SFMEs) before polymerization. It is found that previously mesostructured, surfactant-free mixtures can produce porous polymers of different morphologies, while unstructured, oil-rich regions lead to solid, transparent polymers without nanostructured morphologies. Additionally, a surfactant-based reference system shows similar phase behavior and polymer morphologies as the comparable surfactant-free system, indicating the importance of the hydrotropic behavior of HEMA in this system.
