The discovery and control of new phases of matter is a central endeavour in materials research. The emergence of atomically thin 2D materials, such as transition-metal dichalcogenides and monochalcogenides, has allowed the study of diffusive, displacive and quantum phase transitions in 2D. In this...

近日,美国莱斯大学(Rice University)Hanyu Zhu & Boris I. Yakobson,在Nature Materials上发表评述文章,首先讨论了“ 手性二维材料2D chiral materials”的定义和数学描述,以及范德瓦尔斯2D同质双层和异质结构中的结构手性,以及所带来的物理现象,如圆二色性...
论文说提到:这些人类活动所产生的影响是巨大且出乎意料的,因此有人提议将现在人类所处的地质年代改名为「人类世」。 参考链接: https://www.theguardian.com/environment/2020/dec/09/human-made-materials-now-outweigh-earths-entire-biomass-study https://www.nature.com/articles/s41586-020-3010-5...
Interpreting heat maps in hole-electron analysis within DFT allows researchers to gain valuable insights into the electronic properties of materials. These insights are fundamental for designing and optimizing materials for electronic devices, catalysis, and various other applications in materials science ...
A wide range of natural materials exploit a combination of cellular and composite microstructures for increased mechanical efficiency. Wood, for instance, is made up of a honeycomb-like cellular structure with composite cell walls, with cellulose fibres reinforcing a matrix of lignin and hemi- ...
