in this paper, nano fibers (engelhard corporation titanosilicate number 10 / polyacrylonitrile) ets-10 / pan, as a composite exchanger to absorb heavy metals, were synthesized and optimized. several parameters were affected on this absorption. results show that the optimization sizes of the nano fibers are about 75 nanometers. structures were analyzed by scanning electron microscope (sem) and e...

This study focuses on the topological optimization of adhesive overlap joints for structures subjected to longitudinal mechanical loads. The aim is reduce peak stresses at joint interface elements. Peak in such can lead failure both and structure itself. A new approach based Rational Approximation Material Properties (RAMP) Finite Element Method (FEM) has been proposed minimize multi-layer comp...
