The polymorphism of bicalutamide and the factors affecting its crystal formation have been studied. The standard forms of bicalutamide were prepared by evaporat ion and meltingª²cooling processes. Two crystalline f...

A high gravity co-precipitation method has been used to prepare a copper-based catalyst, and the effects of varying the rotation speed of the packed bed, pH o f precipitation, aging time and other conditions on the properties of the ...

A series of MCM-22 zeolite catalyst samples have been prepared with nitric acid as peptizator using an extrusion molding method. The zeolites were characterized by means of particle...

Since the surface tension value under a plane surface is too high and the calculated critical work to trigger nucleation is too low, the surface tension value under a concave surfac...

2,2,6,6-tetramethylolcyclohexanol (TMC) has been synthesized by consecutive aldol condensation and Cannizzaro reactions of cyclohexanone and formaldehyde with an alkaline catalyst. ...

Analysis of Chinese ink has been carried out by scanning electronic microscopyª²energy dispersive X-ray spectroscopy (SEM-EDS). Preliminary separation of the sample was found to be ...

Biodegradable films of poly(3-hydroxybutyrate-co-4-hydroxybutyrate) copolymers with different compositions were prepared by a solvent evaporation technique. The weight losses and ch...

Chitosan (CTS) has been modified by inorganic impregnation to prepare an CTS-Fe flocculant. The flocculation behavior of the resulting material was investigated with kaoline. The re...

Microspheres containing berberine and polylactic acid were prepared by an oil-in-water emulsifying solvent-evaporation process. The proportions of berberine and polylactic acid, dic...

A new type of linear triblock copolymer, poly(isoprene-ran-styrene)-(butadiene-ran-isoprene)-(isoprene-ran-styrene) (PSI-PIB-PSI) has been synthesized in two steps by continuous ani...

Layers of poly (acrylic acid) (PAA)£¬polyacrylamide (PAM) and maleic anhydride(MAH) have been synthesized on polypropylene (PP) films by a surface photografting modification method ...

Doxorubicin (DOX)-loaded poly(lactic acid)-poly(ethylene glycol)-poly(lactic acid) (PLA-PEG-PLA) microcapsules have been prepared by a double emulsion technique and characterized by dynamic laser light scatt...

Indomethacinª²polybutylcyanoacrylate nanoparticles (IMC-PBCA) have been prepared using emulsion polymerization with biodegradable polybutylcy- anoacrylate as a carrier material. The preparation procedure was...

The Hilbert-Huang Transform (HHT) is more effective in processing nonlinear and nonª²stationary signals than traditional signal processing methods, but three problems need to be considered before it can be u...

A simplification method, based on vertex removal of triangles, for the 3DS MAX model in Virtual Reality Modeling Language (VRML) is introduced. The method involves three main steps. The first step is to choo...

The velocity distribution in the tube in a Kenics static mixer under laminar flow has been simulated by CFD software with two different velocityª²inlet boundary conditions, namely a...

An improved nonlinear principal component analysis (NLPCA) strategy, based on an auto-associative neural network and combining the merits of wavelet analysis and independent compone...
