The mean size of the CaCO(3) particles was about 160 nm. According to scanning electron microscopy observations, the composite with SEBS showed a morphology in which SEBS Selleck Stem Cell Compound Library domains and CaCO(3) particles were independently dispersed in the PP matrix. On the other hand, the composite with C-SEBS showed a morphology in which CaCO(3) particles were encapsulated by C-SEBS; that is, a core-shell structure was formed. The Izod impact strength of the composite with SEBS was higher than that of the composite with C-SEBS

and the PP/SEBS and PP/C-SEBS binary blends. According to observations of the fractured surface, the stress-whitened area was larger in the composite with SEBS than in the composite with C-SEBS and the PP/SEBS www.selleckchem.com/products/17-DMAG,Hydrochloride-Salt.html and PP/C-SEBS binary blends. The toughening mechanism of the composite, using nanometer-sized CaCO(3) particles in combination with SEBS, was examined. (C) 2009 Wiley Periodicals, Inc. J Appl Polym Sci 114: 919-927, 2009″
“Background Skin necrosis after soft tissue

augmentation with dermal fillers is a rare but potentially severe complication. Nitroglycerin paste may be an important treatment option for dermal and epidermal ischemia in cosmetic surgery. Objectives To summarize the knowledge about nitroglycerin paste in cosmetic surgery and to understand its current use in the treatment of vascular compromise after soft tissue Selleck OICR-9429 augmentation. To review the mechanism of action of nitroglycerin, examine its utility in the dermal vasculature in the setting of dermal filler-induced ischemia, and describe the facial anatomy danger zones in order

to avoid vascular injury. Methods A literature review was conducted to examine the mechanism of action of nitroglycerin, and a treatment algorithm was proposed from clinical observations to define strategies for impending facial necrosis after filler injection. Results and Conclusions Our experience with nitroglycerin paste and our review of the medical literature supports the use of nitroglycerin paste on the skin to help improve flow in the dermal vasculature because of its vasodilatory effect on small-caliber arterioles.”
“This paper deals with the development of nanocrystalline Cu-Ni and Fe-Ni thin film thermocouples (TFTCs) by using ion-assisted anodic vacuum arc deposition technique. The crystallographic structure and surface morphology of individual layer films have been studied by x-ray diffraction and scanning electron microscopy, respectively. The resistivity, temperature coefficient of resistance, and thermoelectric power of as deposited and annealed films have been measured. The observed departure of these transport parameters from their respective bulk values can be understood in terms of intrinsic scattering due to enhanced crystallite boundaries.
