“Poly(lactide) (PLA) nanocomposites were fabricated by solution blending of commercial poly(L-lactide) (PLLA) and biodegradable core shell particles, in which the core shell aluo particles were synthesized via octa polyhedral oligomeric boo silsesquioxane (octaPOSS)-initiated ATM/ATR assay ring-opening copolymerization of a mixture of e-caprolactone and L-lactide to form poly(ecaprolactone-co-lactide) (PCLLA) as rubbery core, followed by polymerization of ‘D-lactide to form poly(D-lactide), (PDLA)

as outer shell. The outer PDLA layer could facilitate strong interactions between core shell rubber particles and PLLA matrix Rubber toughening-PLA POSS-rubber-POLA content (wt%) via formation of stereocomplex. The randomness of PCLLA and the subsequent grafting of PDLA were monitored using nuclear magnetic resonance (NMR). The rubbery characteristic of PCLLA was confirmed by differential scanning calorimetry

(DSC) which showed a Tg of –7 degrees C. Stereocomplexation between PLLA and POSS-rubber-D was confirmed using Fourier transform infrared spectroscopy (FT-IR), DSC, and X-ray diffraction (XRD). The resulting biodegradable nanocomposites exhibit a 10-fold increase in elongation at break while maintaining other mechanical properties such as Young’s modulus and tensile strength. XRD, light scattering, scanning electron microscope (SEM), and thermogravimetric analysis (TGA) studies suggested that strong stereocomplex matrix/rubber interactions, good particle dispersion, rubber-initiated SNS-032 molecular weight crazing, and low rubber content are the possible mechanisms behind such significant enhancements.”
“Green, white and black teas were assayed for inhibition of pancreatic lipase activity in vitro. White tea proved to be more effective than green tea with black tea showing little inhibition even at 200 mu g GAE/ml. The EC(50) values for inhibition were 22 mu g/ml for white tea and 35 mu g/ml for green tea: both easily achievable from normal infusions of tea. Liquid chromatography-mass spectroscopy analysis showed that white and green teas had essentially equal amounts of flavan-3-ols but green tea had higher levels of flavonols. White tea had higher levels of 5-galloyl quinic acid, digalloyl glucose, trigalloyl glucose and the tannin, strictinin.
