Granular packings under gravity in frictional and frictionless silos were simulated and the influence of the wall friction on the normal force distribution was
Pure ZnO and indium-doped ZnO (In-ZO) nanoparticles with concentrations of In ranging from 0 to 5% are synthesized by a sol-gel processing technique.The structur
Ceramics usually have irregular grains,cracking,or porosity,which result in their lightproof.Y2Mo3O12 ceramics have more porosity due to the heavy hygroscopicit
