this work is focused on synthesis of sio2- cnt hybrides via sol-gel method. homogeneous distribution of carbon nanotubes within silicon matrix was obtained by mixing the functionalized carbon nanotube (cntcooh) with active silicic acid followed by titration to the solution of sodium silicate (na2sio3) under the average temperature condition of 80?c. different ratios of multi-walled carbon nanot...

We examine the percolation model by an approach involving lattice animals, divided according to their surface-area-to-volume ratio. Throughout, we work with the bond percolation model in Z. However, the results apply to the site or bond model on any infinite transitive amenable graph with inessential changes. For any given p ∈ (0, 1), two lattice animals with given size are equally likely to ar...

The rheologic properties of senescent erythrocytes have been examined using two models of red blood cell (RBC) aging. In the rabbit, aged erythrocytes were isolated after biotinylation, in vivo aging, and subsequent recovery on an avidin support. Aged RBCs from the mouse were obtained using the Ganzoni hypertransfusion model that suppresses erythropoiesis for prolonged periods of time allowing ...

Abstract. We examine the percolation model on Zd by an approach involving lattice animals and their surface-area-to-volume ratio. For β ∈ [0, 2(d − 1)), let f(β) be the asymptotic exponential rate in the number of edges of the number of lattice animals containing the origin which have surface-area-to-volume ratio β. The function f is bounded above by a function which may be written in an explic...

Unique specifications of metal foams such as relatively low cost, ultra-low density, high surface-area-to-volume ratio, and most importantly, the ability to mix the passing fluid provide them a great potential for a variety of thermal-fluidics
