An inorganic, biodegradable silica gel fiber (SGF) acts as a physical scaffold to aid the growth of new cells and the collagen structure that supports them. As a scaffold, it can also be used to deliver drugs over a wide area to aid in healing. The material is integrated into the tissues and...

Energy-saving nozzles offer droplet sizes down to 25 microns, at operating pressures as low as 100 psi. Nozzle passages, including metering slots, spin chambers, and exit orifices, are designed to minimize pressure drop, resulting in conservation of pump energy up to the exit orifice.

Synthesis of heterocyclic aromatic compounds has been pursued for a long time by chemists in order to analyze their properties and potential applications in biomedical and materials sciences including electronic devices such as organic light emitting devices (OLEDs) and in hydrogen storage.

A company must achieve standard, non-halogenated fire retardancy on cabling. Methods may include plastic compounds, coatings, polymers, or additives. The UL tests define the fire-retardant properties that the cable must exhibit after treatment — notably, ignition resistance, flame spread resistance after ignition,...

An organization seeks innovative processes or coatings for steel. The application requires that a normal force be applied between two lubricated steel surfaces. Excessive normal force results in system power losses and increase in wear; the desired solution will permanently increase the coefficient of friction so...

A synthetic leather material delivers a durable touch-feel. The design is based on the way that the human fingertip interacts with surfaces along four different axes of material properties. The fingertip determines whether a surface is soft or hard, smooth or coarse, wet or dry, and warm or...

The PACE Hf, a high-flow proportional valve utilizing a Parker Advanced Technology actuator, delivers 180 slpm of air at 30 psi. The product has low power requirements: steadystate 0.6 Watts max, cycling 15 Hz, 1.2 Watts. The Viva piezoelectric actuator provides repeatability...

A process to enhance the electron-hole wave functions overlap – resulting in high-efficiency quantum well light-emitting diodes (LEDs) emitting in the green and yellow wavelengths – has been developed. This proposed technique changes the polarity of the structure and diminishes the piezoelectric effect. It is...

A company seeks alternative ways of preparing crucibles for the vapor deposition process. Currently, up to a kilogram of an alkalihalide salt is melted electrically in a tantalum crucible within a vacuum chamber, and the vapor is deposited on a metal substrate. The...

New home-use and point-of-care diagnostic medical technologies are needed. The diagnostics kits should monitor diseases not easily measured. Testing may be done within the device, or the device may be a tethered testing head that reports to a central diagnostics facility. The product can be...

NASA Goddard Space Flight Center is a leader in developing satellite-based laser technology for remote sensing measurements of the Earth and other planetary bodies. Laser performance for such missions must be highly efficient and stable over long periods of time...

A flexible mirror film electrically switches between reflective and transparent states. By applying (+) voltages, hydrogenation occurs and creates transparency. When (-) voltages are used, the switchable mirror returns to its original reflective state within 10 seconds. The technology allows...
