Metal Oxide Nanowires as Gas Sensing Elements: from Basic Research to Real World Applications
out of 5 stars
21 Sep 2009 | | Contributor(s):: andrei kolmakov
Quasi 1-D metal oxide single crystal chemiresistors are close to occupy their specific niche in the real world of solid state sensorics. Potentially, the major advantage of this kind of sensors with respect to available granular thin film sensors will be their size and stable, reproducible and...

Molecular dynamics simulation of forced protein unfolding
Nanotribology, Nanomechanics and Materials Characterization Studies
29 Mar 2009 | | Contributor(s):: Bharat Bhushan
Fundamental nanotribological studies provide insight to molecular origins of interfacial phenomena including adhesion, friction, wear and lubrication. Friction and wear of lightly loaded micro/nano components are highly dependent on the surface interactions (few atomic layers). Nanotribological...

It can display, edit, analyze, process, save and print 8-bit, 16-bit and 32-bit images. It can read many image formats.
Illinois Center for Nanoscale Science and Technology and Nano-CEMMS: A Hard Day in the Life of a Soft Cell
07 May 2009 | | Contributor(s):: Jeffrey Fredberg
AHard Day in the Life of a Soft CellWith every beat of the heart, inflation of the lung, or peristalsis of the gut, cell types of diverse function are subjected to substantial stretch. But what physical laws govern the abilities of the cytoskeleton to deform, contract, and remodel at the...

Quantitative, Kinetic Models of Cellular Circuits
25 Feb 2009 | | Contributor(s):: Michael R. Brent
Living cells contain complex, analog circuits that regulate the rate at which each gene produces its product. The kinetic properties of these circuits enable cells to respond to changes in their environments and thus to survive, reproduce, and compete. For decades, molecular biologists have been...
"Who Owns Truth?" - Biomedical Research in a Health Policy Context
13 Mar 2009 | | Contributor(s):: Samuel A. Richmond
This presentation examines a claim made by PhRMA on behalf of pharmaceutical manufacturing companies of America, and the response of the International Committee of Medical Journal Editors (ICMJE) questioning drug company publication policies and practices. Also considered are changes in law...

Multi-walled Carbon Nanotubes and Mesothelioma: An ICON Backgrounder
19 Feb 2009 | | Contributor(s):: Kristen Kulinowski
Two studies published in the Journal of Toxicological Sciences and Nature Nanotechnology in 2008 have demonstrated that some multi-walled carbon nanotubes (MWCNT or MWNT) can induce in mice a response similar to that induced by certain asbestos fibers. At a first glance, certain MWCNT and...
Basic Rules of Protein Folding
31 Dec 2008 | | Contributor(s):: Seth Lichter
How are proteins made? Inside cells, messenger RNA first instructs the ribosomes as to the order which amino acids should be joined together. Linked together and released from the ribosome, the protein is not functional. It now needs to fold into a precise three-dimensional shape. There are no...

Hydration Dynamics in an Amphiphilic Nanostructure under Controlled Hydration Conditions
16 Sep 2008 | | Contributor(s):: Amitabha Chattopadhyay
Amphiphilic surfactants self assemble to form reverse (or inverted) micelles in non-polar solvents in which the polar head groups of the surfactant monomers cluster to form a micellar core directed toward the center of the assembly and the hydrophobic tails extend outward into the bulk organic...
Cataract, Myopathy and Keratitis: Possible use of Nanoparticles
16 Sep 2008 | | Contributor(s):: Ch. Mohan Rao
Small heat shock proteins are critical for several cellular functions. Failure of heat shock proteins, thus, can cause compromised cellular activity leading to disease. Fungal Keratitis is an eye dieses that can be treated with anti fungal drugs. Availability of the drug at the site of action is...
