Objective To observe effect of aluminum on the changes of number and structure of neurons in brain and granulovacuolar degeneration (GVD)in hippocampus in rats and to provide some evidences on the mechanism of neurotoxicity.

The magnetic particles prepared through coprecipitation suspend stably in the fluid of polydimethylsiloxane after twice dispersing,and so the polydimethylsiloxane based ferrofluid is prepared.

But changes in magnetization orientation(superparamagnetism) tend to occur when the size of magnetic particles is reduced below its critical size ,resulting in lost information, and the media can not be used for data storage any more- So reducing the critical size and increasing the thermal stability of magnetic particles are the keys to high density of data storage.

Herein, a novel high-throughput SNP genotyping method using magnetic particles (MPs) in situ PCR and universal tags was described.

Studies of the Particle Characteristics of Vinylidene Chloride -co-Methyl Acrylate Resin by Suspension Copolymerization;

Effect on cement properties of particle characteristics of fly ash

Gas-liquid-buoyant particle three phase stirred tank/reactors are widely used in many industries and very few studies involve in the effect of buoyant particle characteristics on the solid-liquid suspension and gas-liquid dispersion.
