A Finite Element Comparison Between Two Sizes of NiTi Commercial Staples Used in Scaphoid Fracture Fixation
Most carpal bone fractures occur in the scaphoid. The most suitable size of NiTi shape memory alloy (nitinol) staples to heal scaphoid fractures was found by comparing two commercially available compression st...

Surface free energy effects on the postbuckling behavior of cylindrical shear deformable nanoshells under combined axial and radial compressions
In the traditional continuum mechanics, the effects of surface free energy are generally ignored. However, this cannot be the case for nanostructures because of their high surface to volume ratio; surface ener...

A thermal decomposition route for synthesis of silver ribbons
In the presence of dodecylamine, which can serve as the medium and at the same time as the stabilizing reagent, ribbons made of metallic silver were produced by thermal decomposition of silver phthalate. As th...
