An Ionic Twist on Hair Care

Nanomaterials developed by NASA play a big role in professional hairstyling tools.

Disinfecting can be dirty work. Typical cleaning agents, like chlorine and alcohol, release fumes that don’t go away when applied in the contained environment of a spacecraft. So NASA scientists developed an alternative method to keep surfaces disinfected, using a material whose antimicrobial properties have long been known: nanosilver.

The GigE Vision® Interface Standard: Transforming Medical Imaging

Live, high-resolution imaging is increasingly being leveraged to enhance operating procedures. It can improve the precision of physicians and their instruments, and minimize the invasiveness of many procedures. Increasingly, one small component in a vision system — the interfacing technology — is providing answers to the most common of these challenges.

The Future Looks Dimmer

New LED Controller Technology Could Make Dimming Problems a Thing of the Past

Originally fueled by environmental concerns and the steadily rising cost of electricity, the market for energy- efficient lighting has been dramatically accelerated by regulations that will restrict the sale of most incandescent bulbs in North America, Europe, and Asia.

Specifying Gaskets for Outdoor LED Lighting Fixtures

LED lighting technology has the potential to lower energy consumption and reduce maintenance costs on outdoor installations such as area lighting and parking lights, street lights and other “difficult to reach” outdoor locations. When operating in controlled temperatures and weatherproof environments, solid state LED lights are designed to operate for 5 to 10 years. Outdoor LED housings and lighting enclosures are constructed from powder coated aluminum to resist the effects of direct sun and weather for many years. However, if the full payback on the investment in outdoor LED lighting is to be realized, the gaskets required to protect the solid state electronics must function for the 5 to 10 year life of the product.

Researchers Study How to Avoid Charge Traps in Plastic Electronics

Plastic electronics hold the promise of cheap, mass-produced devices. But plastic semiconductors have an important flaw – the electronic current is influenced by “charge traps” in the material. These traps, which have a negative impact on plastic light-emitting diodes and solar cells, are poorly understood.

New ‘Spintronic’ LED Technology Promises Brighter TV and Computer Displays

Physicists at the University of Utah have invented a new “spintronic” organic light-emitting diode (OLED) that promises to be brighter, cheaper and more environmentally friendly than the kinds of LEDs now used in television and computer displays, lighting, traffic lights and numerous electronic devices.

Optimizing Finite Element Material Models in a Crash Test Dummy

Finite element representations of crash test dummies are widely used in the simulation of vehicle safety systems. The biofidelity of such models is strongly dependent on the accurate representation of the nonlinear behavior of the constituent rubber, plastic, and foam materials. Advanced material models are often needed to capture the dynamic response of the various parts of the dummy. The process of calibrating a finite element material model is resource-intensive, as it involves optimizing model parameters to achieve good correlation with test data under different loading conditions and rates.

The Evolution of AdvancedTCA How Far Has It Come?

AdvancedTCA (ATCA) continues to evolve to meet not just the market demands for the telecom central office, but networking, data center, medical, and military communications applications. The two main goals that ATCA suppliers have been trying to solve often conflict with each other: offering more performance in less space, while meeting the specific market and compliance requirements for each industry.
