A rapid and efficient microwave irradiation solid-phase synthesis method was developed for the preparation of the reduced form of oxytocin and lysipressin on Rink amide-MBHA resin by an Fmoc/t-Bu orthogonal protection strategy.

Under high pressure and microwave irradiation, a series of 9-aryldecahydroacridine derivatives were synthesized by the reaction of aromatic aldehydes, 1,3-cyclohexanedione and NH4OAc in enthanol.

Under high pressure and microwave irradiation ,a series of 7,7-trimethyl-3-carboxylates-4-aryl-5-oxo-1,4,5,6,7,8-hexahydroquinoline were synthesized by the reaction of aromatic aldehydes,5,5-dimethyl-1,3-cyclohexanedione and ethyl acetoacetate using NH4OAc as Catalyst in enthanol.

Microwave-Assisted Ullmann-Coupling Reaction of Benzotriazole and Iodobenzene;

A series of 3-naphthyl-2-[(un)substituted phenyl]-1,3-thiazolidin-4-ones were synthesized by the three-component one-pot cyclocondensation of naphthylamine, aromatic aldehyde and 2-mercaptoacetic acid using a microwave-assisted method in the presence of DMAP/DCC.

Many novel and efficient methods have been used to synthesize the aimed-products,such as solvent-free,solid phase,ionic liquid and microwave assisted,and the catalytic synthesis with the novel reagents of Pd,Cu,Mn,Sc etc.

A new micro-positioning control system using PZT for ultra-precision grinding was designed.

Precision machining technology is a research field mainly sponsored by the country, and micro-positioning system with high performance is the key to realize precision machining.

A friction drive is ideal for micro feed systems with long strokes because of its simple structure and small backlash.
