The Influence of Defects on the Morphology of Si (111) Etched in NHF

January 1, 2005
Author(s)
Hui Zhou, Joseph Fu, Richard M. Silver
We have implemented a kinetic Monte-Carlo (KMC) simulation to study the morphologies of Si (111) surfaces etched in NHF. Although our initial simulations reproduced the previous results from Hines, it failed to produce the morphologies observed in our

The Internet Marketplace and Digital Rights Management

Lacking physical control over Internet receiving environments, traditional information security methods cannot fully protect digital products. Insisting upon physical control severely restricts the Web market for digital objects and stymies e-commerce

Triglycidylamine Crosslinking of Porcine Aortic Valve Cusps or Bovine Pericardium Results in Improved Biocompatibility, Biomechanics and Calcification Resistance - Chemical and Biological Mechanisms

January 1, 2005

J Connolly, E Alferiev, J N. Clark, Naomi Eidelman, M Sacks, E Palmatory, A Kronsteinter, S DeFelice, J Xu, R Ohri, N Navneet, N Vyavahare, R J. Levy
We investigated a novel polyepoxide crosslinker that was hypothesized to confer both material stabilization and calcification resistance when used to prepare bioprosthetic heart valves. Triglycidylamine (TGA) was synthesized via reacting epichlorhydrin and
