Liquid metal has been used as a coolant for system-level thermal management for decades in nuclear reactors. The reason is its efficiency — liquid metal can have an effective thermal conductivity 10 to 100 times the thermal conductivity of copper. However, cost and long-term...

PYROFAST is a needle-free injection system with pyrotechnical gas propulsion that provides accurate and comfortable drug delivery through the skin for intra-dermal, subcutaneous, and intra-muscular injections of liquid and solid (lyophilized) drugs. The needle-free injection occurs within...

SiGe is an important semiconductor alloy for high-speed field effect transistors (FETs), high-temperature thermoelectric devices, photovoltaic solar cells, and photon detectors. The growth of SiGe layer is difficult because SiGe alloys have different lattice constants...

Alternative computational strategies for the Discrete Fourier Transform (DFT) have been developed using analysis of geometric manifolds. This approach provides a general framework for performing DFT calculations, and suggests a more efficient implementation of the DFT for applications...

In this innovation, light weight, high temperature, compact aerospace structures with increased design options are made possible by using self-assembling, flexible, pre-ceramic composite materials. These materials are comprised of either ceramic or carbon fiber performs, which are...

A company seeks technology to spray waterborne substances — both suspensions and solutions — on all sides of an object, even the under sides, regardless of the attitude of the object or the direction from which the spray impinges. Nearuniform coating on all surfaces of the object is...

A company seeks a replacement for triclosan, a popular anti-microbial agent used in household products. The replacement requires thermal stability to withstand manufacturing temperatures (such as polymer melt temperatures during molding), UV stability, and compatibility with anionic detergents. It should also be...

A stark reminder of our country’s outdated infrastructure is the sight of uniformed utility company personnel canvassing neighborhoods to read electric and gas meters in homes and businesses. For many residents, this means having to arrange access for meter readers. I have circumvented this issue by doing my own readings...

Like other sectors, the market for microelectromechanical systems (MEMS) stagnated during the economic downturn. According to a report by market research organization Yole Developpement titled “State of the MEMS Industry 2009 Report,” sales of MEMS-based products are slated to reach $6.9 billion in 2009,...

This week’s question concerns net neutrality. The Federal Communications Commission last week began drafting legislation that would prevent phone and cable companies from abusing their control over the broadband access market, by prohibiting them from censoring certain kinds...

This week’s question concerns the health-care reform bill. One of the controversial bill’s provisions, now in Congressional debate, revolves around an escalating series of fines that would be imposed on individuals refusing to purchase health insurance. The fines, slated to take effect starting...
