چکیده
This study presents the effects of current density limit on flash sintering and formation nanostructures in undoped ZnO. The combination high electric field low (1 2 A/cm2) results hot spots fracture as well ZnO vicinity spots. Such phenomena were not observed case higher 3 A/cm2. A detailed microscopy analysis revealed that growth initiated from liquid phase regions at grain boundaries within grains.

simulation and experimental studies for prediction mineral scale formation in oil field during mixing of injection and formation water
abstract: mineral scaling in oil and gas production equipment is one of the most important problem that occurs while water injection and it has been recognized to be a major operational problem. the incompatibility between injected and formation waters may result in inorganic scale precipitation in the equipment and reservoir and then reduction of oil production rate and water injection rate. ...
Electrosynthesis and optical modeling of ZnO nanostructures
Optical modeling was applied for obtaining absorbance spectra and band gap values for different morphology of ZnO semiconductor. In optical modeling, the relative permittivity scalars of zinc oxide coral like nanorods were calculated using the Bruggeman homogenization formalism. ZnO nano rods (ZONRs) as a nucleus layer were fabricated on the Indium Tin Oxide (ITO) by chronoamperometry (CA) in a...
متن کاملLiquid Nanostructures: Phase Transitions, Forces and Friction
Grand canonical Monte Carlo calculations and molecular dynamics simulations are used to investigate binary mixtures confined between chemically patterned surfaces. For certain patterns and surface separations, a surfaceinduced phase consisting of liquid “bridges” joining like-patterned regions of the plates is observed. Furthermore, since these bridges involve liquid-liquid interfaces their sha...
متن کاملThree-Dimensional ZnO Hierarchical Nanostructures: Solution Phase Synthesis and Applications
Zinc oxide (ZnO) nanostructures have been studied extensively in the past 20 years due to their novel electronic, photonic, mechanical and electrochemical properties. Recently, more attention has been paid to assemble nanoscale building blocks into three-dimensional (3D) complex hierarchical structures, which not only inherit the excellent properties of the single building blocks but also provi...
