ABSTRACT Internal oxidation has been identified as an effective method for enhancing the strength of AgMg alloys. However, the concurrent occurrence of embrittlement remains inadequately understood, thus limiting their broader application. This study investigates the oxidation behavior of AgMg alloys with Mg concentrations ranging from 1 at% to 7 at ...

ABSTRACT This study developed a FeSiAl@LMPGP composite material to address the demand for low‐frequency electromagnetic absorption. Through controllable heat treatment, FeSiAl particles and PbO nanoparticles self‐assembled into a high‐density Mott–Schottky heterointerface structure, which exhibited a significant built‐in electric field (BIEF) effect ...

ABSTRACT SnTe is considered a potential alternative to PbTe for thermoelectric applications. However, excessive carrier concentration and thermal conductivity result in poor thermoelectric performance. Herein, p‐type SnTe‐based materials Sn0.8‐xMn0.1Pb0.1SbxTe were synthesized, and the combined effects of Sb, Mn, and Pb were systematically investigated.

ABSTRACT Organic‐inorganic metal halide perovskite solar cells (PSCs) are promising for photovoltaics due to their excellent optoelectronic properties. However, achieving high efficiency and stability remains challenging, mainly due to defects and energy losses at the electron transport layer (ETL)/perovskite interface.

ABSTRACT Dielectric ceramics are popular for energy storage materials because of their rapid charge–discharge characteristics, whereas their low energy density and efficiency hinder their miniaturization and integration. In this work, the energy storage performance is significantly enhanced through introducing Al2O3 and TiO2 into the 0.425(Bi0.5Na0.5 ...

Gallium‐Doped α‐MnO2 Cathode for High‐Performance Aqueous Zinc‐Ion Batteries
ABSTRACT Rechargeable aqueous zinc‐ion batteries (ZIBs) have received significant attention because of their high safety and low cost. MnO2 as a cathode material hampers the application of ZIBs due to its structural instability and dissolution during the operation of the battery.

本文通过计算和实验探索了用逆向喷流降低头部驻点区热流率和减小阻力的方法。 初步计算和实验结果表明:喷流对降低头部驻点区热流率和减小阻力有一定效果,靠近驻点区降热和减阻的效果最明显,远离驻点区(>50度)效果不明显,而中间区(30°~45°)不稳定,有时热流率会明显增大。 在实际应用中 ...

Occurrences of dust storms and long‐distance movement of dust across landscapes is constantly increasing in south Asia. This dust is expected to have profound impact on vegetation health and sustainability as dust may contribute to nutrient budgets of the forest ecosystems, while it could impart various stresses to the plants.
