Article Abstract
Solid-state thermal decomposition in the Cu-13.3Ti-3.8Zr (at.%) alloy was studied using a synthesized method, including the temperature-concentration gradient and differential scanning calorimetry experiments within a single experimental cycle, as well as first principle calculations. Experimentally, the decomposition pathway and the solid solubility of Ti/Zr in the Cu matrix in the temperature range of 820 °C to 801.5 °C were observed in the Cu-13.3Ti-3.8Zr (at.%) alloy. The primary solid phase is (Cu) phase and subsequently precipitated CuZr and CuTi phases. These features are valuable for understanding the thermal stability and solid-state phase equilibria of the alloy. First principle calculations, including formation enthalpy, charge density, and electron localization function analyses, were conducted to evaluate the thermal, structural, and electrical stability of CuZr with and without Ti doping, as well as CuTi. The present work introduces an effective strategy for determining both the solid-state thermal decomposition pathway and the phase diagram within the solid-state region within a single experimental cycle.

Stress engineering is an effective way to tune the performance of semiconductors, which has been verified in the work of inorganic and organic single-crystal semiconductors. However, due to the limitations of the vapor-phase growth preparation conditions, the deposited polycrystalline organic semiconductors are more susceptible to residual stress. Therefore, it is of great research significance to develop a low-cost stress engineering applicable to vapor-deposited semiconductors.

Lithium metavanadate (LiVO) is a material of growing interest due to its monoclinic 2/ structure, which supports efficient lithium-ion diffusion through one-dimensional channels. This study presents a detailed structural, electrical, and dielectric characterization of LiVO synthesized a solid-state reaction, employing X-ray diffraction (XRD), scanning electron microscopy with energy-dispersive X-ray spectroscopy (SEM-EDS), and impedance/dielectric spectroscopy across a temperature range of 473-673 K and frequency range of 10 Hz to 1 MHz. XRD and Rietveld refinement confirmed high crystallinity and single-phase purity with lattice parameters = 10.

Heterojunctions have garnered significant attention in the field of photocatalysis due to their exceptional ability to facilitate the separation of photogenerated charge carriers and their high efficiency in hydrogen reaction. However, their overall photocatalytic performance is often constrained by electron transport rates and suboptimal hydrogen adsorption/desorption kinetics. To address these challenges, this study develops a g-CN/MoS@MoC dual-effect synergistic solid-state Z-type heterojunction, synthesized through the in-situ sulfurization of MoC combined with ultrasonic self-assembly technique.

Covalent organic frameworks (COFs) exhibit outstanding structural tunability, clearly defined ion pathways, and remarkable thermal/chemical stabilities, rendering them highly promising candidates for applications in solid-state electrolytes. However, it remains a challenge to develop a versatile method to incorporate both ionic groups and electron-withdrawing units into a single framework for effectively improving the lithium-ion conductivity. Herein, a series of novel [3+3] defective COFs is successfully synthesized featuring active amine/aldehyde anchoring sites for subsequent post-modification, and regulates the ion conductivity through elaborately tuning the anionic/cationic groups and weak/strong electron-withdrawing units.

Sulfide solid electrolytes (SEs) exhibit excellent ionic conductivity and good mechanical properties, but their poor air stability and solid-solid contact performance seriously hinder the wide application of sulfide all-solid-state batteries (ASSBs). Herein, this paper reviews the history and the major breakthroughs in the development of sulfide SEs. The theories of hard-soft-acid-base theory and glass structure theory, as well as several strategies to improve the chemical stability of sulfide SEs, are discussed emphatically.
