Current-induced stabilization of surface morphology in stressed solids.

چکیده
We examine the surface morphological evolution of a conducting crystalline solid under the simultaneous action of an electric field and mechanical stress based on a fully nonlinear model and combining linear stability theory with self-consistent dynamical simulations. We demonstrate that electric current, through surface electromigration, can stabilize the surface morphology of the stressed solid against cracklike surface instabilities. The results also have more general implications for the morphological response of solid surfaces under the simultaneous action of multiple external forces.

Effect of Current Density and Surface Preparation of Steel on Morphology and Texture of Zinc Electrodeposits
On electropolished steel at low current densities, morphology and texture of electrodeposited zinc were investigated. Zinc coating is consisted of hexagonal crystallites laid on each other to produce packets. These packets are of different sizes and are stacked in different orientations to construct a homogeneous coating on steel substrate. This coating does not have texture, i.e., it has a ran...

In the current work, the effect of surface morphology on light emission property and absorption behavior of quasi-columnar macro-porous silicon (PS) was investigated. PS structures with different morphology were synthesized using photo-electrochemical etching method by applying different etching current densities. SEM micrographs showed that empty macro-pores size and porosity of PS layers were...

Potassium is a major nutrient which may play an important role in many processes such as ion homeostasis in plant cells and osmotic adjustment of guard cells during stomatal opening and closing. Pathumthani 1 (PT1) rice has been reported as being a salt sensitive cultivar and has been selected as a model plant in this study to investigate the possibility of improving the osmotic potential, pigm...
متن کاملEfficiency of Horizontal Roughing Filter in Removing Suspended Solids from Effluent of Waste Stabilization Ponds in 2013
Background & Aims of the Study: The Horizontal roughing filters (HRF) are generally formed with three layers. The size of the course at the beginning of the flow path is large and at the end is small. This kind of layering increases absorption capacity while the solids entering the bed–depth gradually separate because of the decline in the holes’ diameters. This stu...
