Science:反直觉?多元金属催化剂,成分越多越均一
2004年,随着高熵合金概念的首次提出 [1, 2],这类由五种或五种以上主要元素组成的新型材料体系迅速引起关注。不同于传统合金以一种元素为主、少量元素掺杂的设计思路,高熵合金将研究重点转向多元素相图中长期未被充分探索的中央区域,各元素的摩尔分数接近相等。

含稀土生物镁合金材料研究现状与展望
Biomedical magnesium alloys have garnered significant attention because of their unique biodegradability, favorable biocompatibility, and suitable mechanical properties. The incorporation of rare earth elements, with their distinct physical and chemical properties, has greatly contributed to enhancing the mechanical performance, degradation behavior, and biological performance of biomedical Mg alloys. Currently, a series of RE-Mg alloys are being designed and investigated for orthopedic implants and cardiovascular stents, achieving substantial and encouraging research progress. In this work, a comprehensive summary of the state-of-the-art in biomedical RE-Mg alloys is provided. The physiological effects and design standards of RE elements in biomedical Mg alloys are discussed. Particularly, the degradation behavior and mechanical properties, including their underlying action are studied in-depth. Furthermore, the preparation techniques and current application status of RE-Mg alloys are reviewed. Finally, we address the ongoing challenges and propose future prospects to guide the development of high-performance biomedical Mg-RE alloys.

Langmuir:蒸发掩膜干燥液体涂层的理论与实验
我们报道了一项由不均匀蒸发通量引起的聚合物溶液干燥膜的空间变化厚度的研究。通过将固体掩模放置在扩散在固体衬底上的蒸发膜上方来施加蒸发通量的受控不均匀性。在干燥结束时,在掩模下面形成了一个凹陷,同时从口罩边缘延伸出过厚部分和可能大于其尺寸的距离。
