Preparation and characterization of a new type active cathode material;

Study on rare earth metal-containing active cathodes;

This paper introduces the chlor-alkali industry in the development of active cathode, and through an alloy electrodes prepared by electrodeposition.

Survey of false negative Gram-negative bacillus in application of Bact /Alert 240 automated blood cul -ture system.;

The potential factors resulting in false negative and false positive were investigated.

But the accuracy of the result is influenced by many factors, which leads to the higher ratio of false positive and false negative in the diagnosis of CHD.

Application of modified diaphragm electrolyzer with activated cathode process;

Economic feasibility analysis of activated cathode electrolyzer revamping;

Development and application of nano-activated cathodes for diaphragm electrolyzers;

Cultivave Vicia faba with the water from Wei River Xinxiang passage,fix its root tips,observe its micronucleus rate after hydrolysis and dyeing and at the same time establish negative control group and positive control group to demonstrate contrast.

The TiB_2 as inert cathode material for aluminum electrolysis, was electrodeposited successfully on carbon cathode as a coating by way of molten salts electrolysis at 800℃ for 3 hours with a current density 0.

Sample of compact TiB 2-MoSi 2 inert cathode is prepared by cold-pressing and sintering.

Some materials,including metal anodees and oxide anodes in the inert anodes and titanium diboron material in the inert cathodes,were especially focused on.
