Acontinuing effort that supplements and complements the one summarized in the immediately preceding article is dedicated to the development of nanowire-based sensor arrays, with emphasis on maximizing the utility of such arrays for real-time sensing of molecular species associated with chemical...

A program of research and development has resulted in some advances in algorithms for computational fluid dynamics (CFD), finite-element simulation of solid objects undergoing large deformations, and some related topics. The main advances are summarized as follows:

Researchers at Virginia Tech, Oak Ridge National Laboratory, and the University of Georgia have proposed using polysaccharides, or sugary carbohydrates, from biomass to directly produce low-cost hydrogen for the new hydrogen economy.

This monthly review lets you "meet" the new advertisers appearing in NTB and its supplements. Here's a sneak peek at the products, services, and offers available from May's first-time advertisers. 3Dconnexion (San Jose, CA) is a provider of 3D navigation devices for 3D design and visualization applications.

A global specialty chemical company is seeking innovative "green" renewable raw materials, products, and processes for replacement of existing non- environmentally friendly solvents, while not compromising the performance or significantly increasing the cost.

NASA's Solar and Heliospheric Observatory (SOHO) now enables scientists to forecast solar radiation storms, giving future astronauts time to seek shelter and ground controllers time to safeguard satellites. The new method offers as much as one-hour advance notice when a storm is approaching.

As part of NASA's Partnership Seed Fund program, Goddard Space Flight Center is integrating the ILIADS software, a geospatial information system (GIS) it developed for lunar applications, with Questus(TM), a management and planning software tool developed by United Space Alliance (USA) for space shuttle operations. The...

This invention provides low-molecular-weight polyesters and polyamides useful for flushing wet pigments and manufacturing color concentrates. More specifically, the compositions of the invention are effective for flushing wet pigments, producing pigment dispersions, and then producing colored polymers with the pigment...

First responders will be able to better prepare individuals with special needs thanks to new open-source software developed at the U.S. Department of Energy's Argonne National Lab. The Special Population Planner software is an extension to commercial ArcView Geographic Information Systems (GIS) software, and provides a...

A team of researchers at the California Institute of Technology (Caltech) has uncovered certain properties of shish-kebabs -- tiny structures that can form when polymers crystallize during flow -- that should lead to improved materials in the most widely used plastics. Shish-kebabs are made of polymers known as polyolefins. In...

Researchers at Purdue University are developing a system that uses mathematical models and sensors to locate passengers releasing hazardous materials or pathogens inside airline cabins. The research has shown that the technique can track a substance to an area the size of a single seat. The technique, called "inverse...

A method is needed to visually detect the presence of pathogenic bacteria or microbes on human hands regardless of the presence of beneficent micro- organisms and without killing the latter. The solution must be safe for humans and easily applicable by a common user. To respond to this Tech Need click here.

A patch of Martian soil analyzed by NASA's rover Spirit is so rich in silica that it may provide some of the strongest evidence yet that ancient Mars was much wetter than it is now. The processes that could have produced such a concentrated deposit of silica require the presence of water.

The Laser-Based Item Monitoring System (LBIMS), developed by researchers at the Department of Energy's Oak Ridge National Laboratory, balances the need for high-resolution monitoring and personal safety with confidentiality and personal privacy. Using low-cost reflective tags placed on objects, LBIMS maps the precise location...

University of Rochester (New York) researchers have developed custom- designed contacts for people with keratoconic eyes, which are rare but disabling. From the side, the eyes look more pointed or cone-shaped than round. The condition causes people to see halos, and double and triple images. About 1 in 2,000 people suffer from the...

CLEANSENS is a non-dispersive infrared gas photometer used to measure the presence and concentration of high-GWP (Global Warming Potential) gases, including HFCs, PFCs, and SF6. It uses a patented dual-beam sensor to achieve a very wide dynamic range of detection. The sensor employs an electrically...
