The influence of oxygen plasma treatment time on the surface morphologies and free energies of Twaron fibers and...

This study explores the catalytic properties of Pt-Ag-Co ternary alloys used for H2O2 reduction. All catalysts are prepared by impregnation reduction method and characterized by XRD and TEM. The electrochemical performance is examined by cyclic voltammetry (CV) at 25°C. The results show that Ag, Co and...

This article by joining the 20ppm water stable medicamentin the standard water sampleand the different dosage the SO42- ion carry onthescaleinhibition performance and the electronic scanning test, and concluded that inhibiting performance plummets with the increase of the amount ofSO42 – ion and explains...

The shifting of layers has great effect on the permeability which is a key parameter in resin transfer molding (RTM). In this paper, a mathematical model was developed to predict the out-of-plane permeability of 0°/45° alternative multilayer fabrics with one extreme structure. The global permeability...

An amorphous Fe-based catalyst supported on polypyrrole-modified graphite is synthesized by a chemical method. The optimal Fe loading with the highest reduction current is 4 wt%. Their morphology, structure and chemical component were characterized by scanning electron microscopy (SEM), X- ray diffraction...

A new method was developed for directly preparing conductive polypyrrole (PPy)/cellulose acetate (CA) composite films by in-situ chemical polymerization. The surface morphology of the films was observed by the atomic force microscopy (AFM). It was found that the composite films were composed of two layers...
