Finite Size Scaling and Quantum Criticality
out of 5 stars
09 May 2007 | | Contributor(s):: Sabre Kais
The study of quantum phase transitions, which are driven by quantum fluctuations as a consequence of Heisenberg's uncertainty principle, continues to be of increasing interest in the fields of condensed matter and atomic and molecular physics. In this field we have established an analogy between...
SPMW FIRAT: A fast and sensitive probe structure for SPM
05 Jan 2007 |
A new SPM probe, called the force sensing integrated readout and active tip (FIRAT), is described and initial experimental results obtained on commercial AFM systems are presented. FIRAT combines a micromachined integrated electrostatic actuator to move the tip and an integrated optical...
Understanding Deformation Processes in Nanocrystalline Metals Through the Use of Real-time Electron Microscopy Techniques
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...
