Waterborne polyurethane(WPU) binder was synthesized by refined alkali lignin(RAL) with 4,4′-diphenylmethane diisocyanate(MDI).Fourier transform infrared spectr
A formula was proved for computing the zeroth-order general Randic index of a hexagonal system to explore the correlation between the zeroth-order general Randi
GAMBIT,POLYFLOW and FLUENT POST were used to simulate the morphology and the velocity of electrospun stable jet.Simulation results shows that jet diameter decre
