Behaviour of Parallel Coupled Microstrip Band Pass Filter and Simple Microstripline due to Thin-Film Al2O3 Overlay

The X-band behaviour of a seven-section parallel-coupled microstrip band pass filter Stoneware Plate and microstripline due to thin-film Al2O3 overlay of different thickness is reported in this paper.This Al2O3 film can give a homogeneous overlay structure.There is a substantial increase in the bandwidth due to the overlay, the pass band extending

Novel Composite Membranes Based on Chitosan Copolymers with Polyacrylonitrile and Polystyrene: Physicochemical Properties and Application for Pervaporation Dehydration of Tetrahydrofuran

Pervaporation has been applied for tetrahydrofuran (THF) dehydration with novel composite membranes advanced by a thin selective layer composed of chitosan (CS) modified by copolymerization with vinyl monomers, acrylonitrile (AN) and styrene, in order to improve the chemical and mechanical stability of CS-based membranes.Composite membranes were de
