A compact crystalline hydroxyapatite coating on Ti-6Al-4V substrate with an atomic intermixed coating/substrate interface about 27 nm in width was synthesized by ion beam assisted deposition (IBAD) and a following post-treatment. The coating after post-treatment was identified by X-ray diffraction as crystalline hydroxyapatite. The interface between(More)
Crystallization temperature of the amorphous calcium phosphate coating synthesized by ion-beam-assisted deposition successfully was decreased to 400 degrees C for the making of orthopedic implants with better qualities. Transmission electron microscopy (TEM) and X-ray diffraction (XRD) were used to investigate the morphological and structural evolution of(More)
An atomic intermixing layer, 25 nm in width, has been identified by high-resolution transmission electron microscopy (HRTEM) and energy-dispersive X-ray spectroscopy (EDS) analysis at the ceramic/metal interface of a hydroxyapatite (HA) coating/titanium implant prepared by an ion-beam-assisted deposition (IBAD) technique and post-heat-treatment process. The(More)
A method was employed for the determination of phospholipid in membrane of peroxisomes by high performance liquid chromatography. The separation was performed on a mu-Porasil Si60 column(250 mm x 4.6 mm i.d.) by gradient elution. The phospholipids were detected at 205 nm. The limits of detection for cardiolipin, phosphatidylinositol, phosphatidylserine,(More)
Peroxisomes of rat liver from normal and di (2-ethylhexyl) phthalate (DEHP)-treated animals were isolated by density gradient centrifuge method. The fatty acids in the liver peroxisomes were extracted with chloroform and methanol, and were esterified with boron trifluoride and methanol. The fatty acids methyl esters were separated on SPB-1 (similar to(More)
Ginsenoside compound-K content in ginseng is very low, while it is the main intestinal bacterial metabolite and the final absorption style of the major components, such as ginsenosides Rbl and Rb2. The determination of ginsenoside compound-K in the fermentation liquor of ginseng saponins by reversed-phase high performance liquid chromatography was(More)
