Synthesis of graphene by PECVD and research on the performance of graphene-based Li-ion batteries [PDF]
, 2016 石墨烯是由碳六元环形成的二维蜂窝状晶格结构，只有一个碳原子的厚度，是第一种真正意义上的二维材料。由于这种特殊的结构，石墨烯拥有一些优异的物理和化学性能，如优异的力学性能、较好的柔韧性、良好的导电性能、很高的电子迁移率、较大的杨氏模量。这使得石墨烯在纳米电子器件、超级计算机、太阳能电池、透明电极等的应用方面具有很高的应用价值。但是所有这一切的前提是需要大规模制备出高质量的石墨烯。目前，石墨烯制备方法已有很多，但是要想实现石墨烯的产业化，就必须针对不同的应用实现石墨烯的大规模、高质量、可调控生长 ...

A Multifunctional Reducing Molecular Dopant for 16% Efficient Tin Perovskite Solar Cells
Rare Metals, Volume 45, Issue 3, March 2026.ABSTRACT Although lead‐based photovoltaics have seen remarkable progress, tin‐based perovskite solar cells (Sn‐PSCs) continue to face challenges due to their limited power conversion efficiency and insufficient operational stability. The primary cause of this performance gap is the susceptibility of Sn2+ to oxidation, which promotes rapid defect ...

Rare Metals, Volume 45, Issue 3, March 2026.ABSTRACT MCrAlX coatings are widely used as bond coats in thermal barrier coating systems to protect turbine blades from high‐temperature oxidation. However, their oxidation resistance is often restricted by uncontrolled microstructures, surface roughness, and aggregation of reactive elements (REs). In this study, high‐repetition‐rate femtosecond laser

The Microstructure Evolution and Mechanical Properties of (FeCoCrNi)100‐x(AlCu)x High‐Entropy Alloys
Rare Metals, Volume 45, Issue 3, March 2026.ABSTRACT This study systematically investigates the effects of AlCu addition on the microstructural evolution and mechanical properties of (FeCoCrNi)100‐x(AlCu)x (x = 0, 5, 10, 15, 20; at%) high‐entropy alloys (HEAs). The results reveal that the microstructure evolves from coarse equiaxed to refined equiaxed, dendritic, and ultimately dual‐phase ...
