After comparing light-emitting diodes against fluorescent lights in meat refrigeration units, Kansas State University’s Kyle Steele found that retailers could save a substantial amount of money by using them, and not just because of the LEDs’ operating efficiency.
A team in Germany has built a transmitter less than a millimeter square that has generated the highest frequency ever attained by a microelectronic device: 1.111 THz. Compared to previous transmitters that have been bulky and expensive, the new device could soon find use in engineering applications.
Researchers have created a new type of optical device, the passive optical diode, small enough to fit millions on a computer chip that could lead to faster, more powerful information processing and supercomputers.
A team of University of Illinois engineers has developed a self-healing system that restores electrical conductivity to a cracked circuit in less time than it takes to blink. Their solution was to adapt a microcapsule healing solution used for polymers to conductive systems.
Atomic force microscope cantilever tips with integrated heaters are widely used to characterize polymer films, and to study fundamentals of nanometer-scale heat flow. Until University of Illinois engineers adapted such a tip to read electrothermal voltage, however, no one had used a heated nano-tip for electronic measurements.
Researchers at Rochester Institute of Technology and PPC Corp., Syracuse, N.Y., have developed a new sensor that, once installed in the connecting units of coaxial cables, can find the exact location of cable damage through a technology called back scatter telemetry.
The following Websites are good sources of information related to the global R&D enterprise. Much of the information in the 2012 Global R&D Funding Forecast was derived from these sources, which are certainly not all-inclusive.
Liotech, a joint venture between RUSNANO and Chinese holding company Thunder Sky, has launched the world's largest high-capacity lithium-ion battery factory near Novosibirsk. Covering more than 40,000-m 2 , it has a design capacity of more than 1 GWh, or approximately one million batteries per year.
W. L. Gore & Associates has introduced new expanded polytetrafluoroethylene (ePTFE) membrane in high-density polyethylene cartridge filters to support the manufacture of high-purity chemicals used in the semiconductor and liquid-crystal display industries.
Determining the friction of a bobsled run can mean the difference between winning and losing, but it has always been more of an art than a science. Researchers have now figured out a way to measure friction level accurately, helping them to build effective simulations prior to the 2014 Olympic Winter Games.
The 100 top innovators have been ranked this week by the Thomson Reuters’ intellectual property (IP) consulting arm. The U.S. continues to lead this list with a large share of innovators, and Asia and Europe place second and third, respectively. However, China is not yet ranked because of its practices regarding protecting IP and commercializing products globally.
A U.S. Department of Energy review panel last week approved a project to create the world’s largest digital camera. Designed for a new Chilean telescope’s 8.4-m primary mirror, the camera has 189 semiconductor sensors that can record infrared to ultraviolet light, and has the capacity to produce 15 terabytes of data every night.
The robotics company famous for building BigDog, a four-legged robot that moves in a fashion that is both strange and disturbingly life-like, has added arms to its two-legged variant, PETMAN. A new video from Boston Dynamics shows in the anthromorphic robot in motion.
Light-emitting diodes (LEDs) are widely accepted as a more efficient and reliable option than tungsten incandescent bulbs. But recent research at Sandia National Laboratories shows that humans are as comfortable with white light generated by diode lasers, which are more efficient than LEDs at higher amperages.
According to a study out Wednesday venture capitalists invested more money in more U.S. startups in the third quarter than they did a year earlier. Though overall investments dropped from the second quarter, the software industry showed especially big jumps in venture capital quarter to quarter.
With a cutting-edge solar car, an advanced strategy and an intrepid 16-student race crew, the University of Michigan's national champion solar car team readies for the 1,800-mile World Solar Challenge in Australia on Oct. 16.
Vying for a $1.65 million purse, the largest aviation prize ever offered, competitors in the Green Flight Centennial Challenge will take to the air this weekend. To qualify, the electric, biofuel, and hybrid-powered planes must exceed 200 passenger miles per gallon, about double what even the best large commercial jets now achieve.
A team from Tel Aviv University has developed superconducting wires using fibers made of single crystals of sapphire to be used in high powered cables. Factoring in temperature requirements, each tiny wire can carry approximately 40 times more electricity than a copper wire of the same size.
Two of the world’s top automakers have teamed up as equal partners to develop a hybrid drive system for rear-wheel-drive light trucks and SUVs.They will independently integrate the new hybrid system in their future vehicles separately.
The editors of R&D Magazine have opened the nominations for the 2012 R&D 100 Awards competition, which will celebrate the 50th anniversary of the awards. If your organization introduced a new product this year, or is planning to, you can begin the entry process now.
Omega’s new CL540ZA thermocouple simulator can be used to calibrate a thermocouple input instrument and can be used for measuring temperature in a manufacturing facility.
On Friday, NASA will launch the most distant probe ever powered by the sun. Equipped with three tractor-trailer-sized solar panels to supply 400 W at the terminus of its 2 billion-mile journey, Juno was designed not out of concern for the environment, but for entirely practical considerations.
With one of the fastest-aging populations in the world, Japan is using robotics to provide automated care solutions. The latest effort at RIKEN, a robot able to lift a human, relies on the first capacitance-type tactile sensors made entirely of rubber to provide the necessary soft touch.
Earlier this week, R&D Daily featured efforts by scientists in Scotland to ferret out fake whisky with spectrometry techniques. In Spain, chemists are going a different route to identify types of cava, a sparkling wine similar to champagne.
Organic light emitting diode (OLED) lighting has the potential to create cheap, pleasing light in unique, flexible form factors. However, the technology is immature and costly. Lux Research reports that OLED lighting costs will drop by more than an order of magnitude over the course of this decade. But the technology will still remain uncompetitive with other lighting options, and amount to a mere $58 million market in 2020.
