A novel multilayer film electrode containing 12-tungstosilicate anions was achieved on the surface of gold electrode by alternating deposition of 12-tungstosilicate anions with 60% quaternized poly(4-vinylpyridine) based on electrostatic interaction. The chemically-modified electrode exhibits a high catalytic activity towards the electroreduction of molecular oxygen.

ENDOPLASMIC reticulum (ER) molecular chaperone glucose regulated protein (Grp94 ), a mem-ber of heat shock protein 90 family, is a relatively abundant luminal protein in the ER. Theexpression of the Grp94 gene is markedly increased under many stress conditions. Grp94 isprimarily involved in folding, assembly and translocation of proteins synthesized within

The hybridized state of each atom changes with various changes of alloying elements and different alloying degrees. It is shown that during the course of alloying, the changes in the microsolid_state reflection such as atomic hybridized state make the corresponding VES parameters change, and that affects the mechanical properties of Fe-3Al alloys.

Using electrode as laser cladding materials, the microstructure and wear resistance of laser clad layer of ductile cast iron was studied. The laser clad layer can be subdivided into the melted zone where existed large amounts of austenite, graphite nodules and some carbides, and the solid state transformation zone which included martensite and austenite below the melted zone. The Ti combined with C to form TiC increasing the wear resistance; The Co significantly increased the wear resistance compared with Ti.

The chromosomes 1, 3, 5, 6, 7,10 and 12 of rice field eel (Monopterus albus Zuiew) have been microdissected successfully from meiosis I diakinesis spreads by using glass microneedlc under an inverted microscope. And the DOP-PCR products of the single chromosome dotted on the nylon membrane as 'specific chromosomal DNA pool', have been hybridized with 6 probes to map these genes. The mapping results show that Zfa has been mapped to chromosome 1, rDNA to chromosomes 3 and 7, both Gh and Pdegγto chromosome 10, Hsl to chromosome 5 and Hox genes have been detected on chromosomes 1, 3, 6 and 10 meantime. It has initiatively been suggested that chromosome 10 of rice field eel might possess the commom conserved synteny to that on chromosome 17 of human, chromosome 11 of mouse, chromosome 12 of pig and chromosome 19 of bovine. And so chromosome 3 of rice field eel might also contain the commom conserved synteny to that on chromosome 2 of zebraf-ish. Our study is an attempt to establish a new and feasible

This paper describes an investigation of the effect of surface morphology on the adhesion of paint to aluminium substrates. Comparisons are made with the surface morphology, both treated with a chromate conversion coating and abraded with emery paper only, and their bond strength to chlorinated rubber lacquer in dry and wet conditions was investigated. Although the surface of a chromate conversion coating is not as rough as that of one abraded with emery paper, it exhibits an excellent bond strength with an organic coating. It indicates that no mechanical inter lock is the main factor affecting the adhesion strength. Furthermore, it shows a promotion of adhesion after immersing in 3% NaCl solution for several days. Chemical analysis of the paint film and metallic substrate reveals that adhesion failure occurs between the paint film and chromate conversion coating.
