Assume, in addition, that the volume density δ(q) varies only in directions locally parallel to the layer’s surface and not along its thickness. An elementary volume surrounding a point q in the layer can be written as dV(q)=h(q)dS, and then the elementary charge in this volume beco...
As a new-era of energy harvesting technology, the enhancement of triboelectric charge density of triboelectric nanogenerator (TENG) is always crucial for its large-scale application on Internet of Things (IoTs) and artificial intelligence (AI). Here, a microstructure-designed direct-current TENG (MD...
Nature Communications volume 15, Article number: 666 (2024) Cite this article 3839 Accesses Metrics details Abstract Keen desires for artificial mimicry of biological polymers and property improvement of synthesized ones have triggered intensive explorations for sequence-controlled copolymerization. However, ...
The amount of electric charge per unit dimension is the electric charge density. A conductor's electric charges could be spread along its length, across its surface, and through its volume.
由于对大体系做量子化学计算产生比较精确的电子密度比较耗时,因此只需要用准分子近似的电子密度(promolecular density)对Hirshfeld surface着色就够了,它直接由各个原子孤立状态的电子密度叠加得到,耗时极低,我实测和使用量子化学计算的电子密度着色的效果差不多。
substantial intraseasonal variability (ISV) (Farrar and Weller, 2006; Kessler et al., 1995; Masumoto et al., 2005; Chen et al., 2019), which plays a vital role in the transportation of heat and volume in the Indian Ocean, and affects regional and global climate change (Schott et al.,...
As moving charges try to take the shortest path (least resistance), we see that, in the curved section of the conductor, the current density varies through the volume significantly. It is largest near the inner radius and smallest near the outer radius. ...
