The residual stresses of the thin-walled injection molding are investigated in this study. It was realized that the behavior of residual stresses in injection molding parts was affected by different process conditions such as melt temperature, mold temperature, packing pressure and filling time. The layer removal method was used to measure the residual stresses at a thin-walled test sample by a...

Sudan I is a carcinogenic compound containing an azo group that has been illegally utilized as an adulterant in food products to impart a bright red color to foods. In this paper, we develop a facile lab-on-a-chip device for instant, ultra-sensitive detection of Sudan I from real food samples using plasmonics-enhanced diatomaceous thin film, which can simultaneously perform on-chip separation u...

Abstract A theoretical model, the phase-field matching theory, has been used to investigate localized states, their associated local vibrational density of coherent conductance, and thermal conductivity perturbed ultra-thin film quasi-dimensional crystalline lattice. The defect disrupts system’s translational symmetry in perpendicular direction it, which is axis Ox, induces a state its behavior...
