Nanoscience and nanotechnology impact our lives in many ways, from electronic and photonic devices to biosensors. They also hold the promise of tackling the renewable energy challenges facing us.

Topological defects such as dislocations in crystalline materials usually have major impacts on materials' mechanical, chemical and physical properties. Detailed knowledge of dislocation core ...

The arrangement of atoms around a screw dislocation in copper has been calculated by a variational method. The pairwise interaction between discrete atoms was represented by a Morse potential function ...

Nanoscale defects such as dislocations have a profound impact on the physics of crystalline materials. Understanding and characterizing the motion of screw dislocation and its corresponding effects on ...

Article Views are the COUNTER-compliant sum of full text article downloads since November 2008 (both PDF and HTML) across all institutions and individuals. These metrics are regularly updated to ...

Abstract: The electro-elastic interaction of a piezoelectric screw dislocation with interface is considered. The surface of layers is assumed to be mechanically free and electrically open. The electro ...

基于LSTM和GRU深度学习模型的合金材料螺位错结构演化及枝晶生长过程时序预测系统。 A deep learning-based time series prediction system ...

Abstract: The interaction between a screw dislocation and a circular piezoelectric inhomogeneity with a crack is dealt with in this paper. The crack expands both along the interface and penetrating ...
