Theoretical modeling of the magnetic properties Fe3O4-Fe3-xTixO4 composites obtained by sol-gel method with subsequent hydrothermal treatment has been carried out. The magnetization reversal fields and number particles in different states an ensemble two-phase infinitely thin boundary between phases a characteristic size varying range from 30 to 80 nm were calculated using "magnetic rectangles"...

background: vascular endothelial growth factor (vegf) is a coordinate regulator of physiological angiogenesis during embryogenesis, skeletal growth and reproductive functions. there are several types of vegf, including vegf165. vegfs stimulate endothelial cell growth, angiogenesis, and capillary permeability. low induction temperature is a major factor for expression of the recombinant vegf165 ...
