Understanding Deformation Processes in Nanocrystalline Metals Through the Use of Real-time Electron Microscopy Techniques
out of 5 stars
03 May 2007 | | Contributor(s):: Eric Stach
It is has long been known that the grain size of a material has a substantial effect on its mechanical strength, through the well-established Hall-Petch relationship. In the past decade or so, there has been a resurgence of interest in this topic resulting from the ability to create metals with...

Orientational Dependence of Friction in Polyethylene
16 Apr 2007 | | Contributor(s):: SeongJun Heo
The frictional properties of polyethylene polymer are investigated by using classical molecular dynamics simulations. Especially, the sliding orientational effect is considered in this study. The results of polyethylene are also compared to those of polytetrafluoroethylene(PTFE).
Planning for Disaster: Designing a Cleanroom to Minimize Risk Should a Disaster Occur
09 Apr 2007 | | Contributor(s):: John Weaver
The cleanliness levels of a cleanroom or other high-technology facility make it inherently vulnerable to a disaster such as a fire. Historically, even a small event of this type can cause significant downtime and cost millions of dollars in remediation. When designing a cleanroom, steps can be...
High-Aspect-Ratio Micromachining of Titanium: Enabling New Functionality and Opportunity in Micromechanical Systems Through Greater Materials Selection
09 Apr 2007 | | Contributor(s):: Masa Rao
Traditionally, materials selection has been limited in high-aspect-ratio micromechanical applications, due primarily to the predominance of microfabrication processes and infrastructure dedicated to silicon. While silicon has proven to be an excellent material for many of these applications, no...
CMOS-Nano Hybrid Technology: a nanoFPGA-related study
04 Apr 2007 | | Contributor(s):: Wei Wang
Dr. Wei Wang received his PhD degree in 2002 from Concordia University, Montreal, QC, Canada, in Electrical and Computer Engineering. From 2002 to 2004, he was an assistant professor in the Department of Electrical and Computer Engineering, the University of Western Ontario, London, ON, Canada....
The Impact of Protein Flexibility on Ligand Binding to Proteins: A Computational Perspective
22 Mar 2007 | | Contributor(s):: Markus A. Lill
Nowadays, computer-aided drug discovery (CADD) concepts are routinely used in academia and industry for identifying and optimizing lead structures. While CADD techniques have been widely used to attain a qualitative understanding of ligand binding to proteins, a current challenge is to quantify...
Computer Simulation of Nanoparticles, Viruses, and Electrical Power-Generating Bacteria
20 Mar 2007 |
Models of cells and nanometer-scale biosystems are presented that clarify their physico-chemical characteristics and allow for computer- aided design of therapeutic and nanotechnical devices. Multiscale techniques are used to obtain rigorous, coarse-grained equations for the migration and...
Antiestrogenic Conjugates as New Breast Cancer Chemoprevention Agents
08 Mar 2007 | | Contributor(s):: Ross Weatherman
Tamoxifen is the first drug specifically approved for the prevention of cancer and arguably the most successful anticancer drug of all time. Although millions of breast cancer patients have benefited from tamoxifen therapy, there are side effects that hinder the broad use of tamoxifen as a...

Introduction to X-ray Photoelectron Spectroscopy and XPS Application for Biologically Related Objects
14 Feb 2007 | | Contributor(s):: Dmitry Zemlyanov
X-ray Photoelectron Spectroscopy (XPS), which is known as Electron Spectroscopy for Chemical Analysis (ESCA), is a powerful research tool for the study of the surface of solids. The technique becomes widely used for studies of the properties of atoms, molecules, solids, and surfaces. The main...
Simple Harmonic Oscillator
15 Feb 2007 | | Contributor(s):: Heng Li
One of the most important model systems in quantum mechanics because a wide variaty of physical situations can be reduced to it either exactly or approximately. In particular, a system near an equilibrium configuration can often be described in terms of one or more harmonic oscillators....
Particle in a Box
The particle in a box (or the infinite potential well) is a simple idealized system that is completely solved within quantun mechanics. The infinite potential well is a finite sized region in space (the box) with an infinite potential at its boundaries ( the wells). A particle experiences no...
