Simulation Reveals How the Body Repairs Balance

When your brain’s neural pathways are impaired through injury, age, or illness, muscles are deprived of the sensory information they need to perform the constant balancing act required for normal movement and standing. In a project designed to build robots that can balance like humans, researchers at Georgia Tech and Emory University have created a computer simulation that sheds new light on how the nervous system reinvents its communication with muscles after sensory loss. The project could help better diagnose and rehabilitate patients with balance problems by retraining their muscles.

Phil Neudeck, Electronics Engineer, NASA’s John Glenn Research Center, Cleveland, OH

The Aeronautics Research Mission Directorate at NASA's Glenn Research Center has developed a new silicon carbide differential amplifier integrated circuit chip that may provide benefits to anything requiring long-lasting electronic circuits in very hot environments. The chip exceeded 1,700 hours of continuous operation at 500ºC - a breakthrough that represents a 100-fold increase in what has previously been achieved. Phil Neudeck is the team lead for this work.

Selective Elimination of Nitrogen Oxides from Exhaust Gases

The Environment Purification Materials team of AIST’s Synergy Materials Research Center (Japan) has successfully developed and tested significantly improved electrochemical reactors for the selective elimination of nitrogen oxides (NOx) in a range of industrial exhaust gases containing oxygen. The inventors have engineered and refined the electrochemical cell anode, cathode, and solid oxide electrolyte to possess nano- and micro-structure control. This fundamental improvement enables very highly efficient operation at low levels of electrical power and current required for NOx decomposition in the presence of excess oxygen.

Chemical Analysis without Reagents

A portfolio of technologies applies mid-infrared spectroscopy to the analysis of fluids. Any fluid can be analyzed, including blood, serum, and other biological fluids. Tests are non-destructive. The techniques require no reagents or other chemicals, and thus there are no chemicals to store or dispose of. The spectroscopic signatures obtained from the samples can be used to aid the diagnosis of disease, among other applications, because molecular signatures are unique. The technique has a high sensitivity to the conformation of the molecule: shape, folding, symmetry, and its state.

Sustainable Processes for Green Polymer Production

Technologies leading to sustainable and green production of polymers are sought. Candidate technologies should fit recently developed definitions for green chemistries. Chemistries that produce safe chemicals, that use safer solvents and auxiliaries, and/or that produce chemicals designed for degradation are preferable. Byproducts of the process should either not be hazardous, or easy and economical to be rendered harmless for people and the environment.

Reflective Aerosol

This technology need is for an aerosol with properties that enable it to be easily launched using a pulsed jet fogger. It also must have reflectivity or other optical properties, and must be safe for human cutaneous and pulmonary contact. The aerosol should have optical properties that can be manipulated using laser light or other light sources to produce large-scale images and other visual effects. The aerosol would be used to create a large image that is visible from multiple vantage points by “painting” the aerosol from within or without in such a manner that a three-dimensional object is emulated.

Portable Microleak-Detection System

Heating or cooling of a vacuum seal enables testing over a wide temperature range. The figure schematically depicts a portable microleak-detection system that has been built especially for use in testing hydrogen tanks made of polymer-matrix composite materials. (As used here, “microleak” signifies a leak that is too small to be detectable by the simple soap-bubble technique.) The system can also be used to test for microleaks in tanks that are made of other materials and that contain gases other than hydrogen. Results of calibration tests have shown that measurement errors are less than 10 percent for leak rates ranging from 0.3 to 200 cm3/min.
