Prediction of the critical volume of alkenes using a quantitative structure property relationship;

The quantitative structure-property relationship(QSPR) of structurally diverse organic compounds and their critical volumes was studied using molecule modeling and the stepwise selection regression method.

A new method based on elements and chemical bonds was developed for estimating critical volume of organic compounds.

The effective dielectric constants ( ff) of three structures , namely , face-centred-cubic (fcc ) , body-centred-tetragonal (bct ) and hexagonal close packed (hcp) were calculated , and the specific values of the effective dielectric constants over the critical volume ratios of these structures were compared.

An equation of the critical volume fraction, fpc, of particle-reinforcement in a composite, including particle size, yield strength of the matrix, dissipation work in the vicinity of the particles and the width of the interface zone, has been educed by the energy theory on the basis of the types of microscopic failure of the composite.

Composite preparation of nano Cu/SBA15 by supercritical fluid deposition

To synthesize a nano-catalyst by using supercritical fluid deposition,it.

Ag/SBA-15 nanocomposite was prepared by supercritical fluid deposition(SCFD) method,with AgNO3 as the precursor and ethanol or glycol as the cosolvent.
