Argonne chemist Lina Chong (foreground) holds a sample catalyst while Argonne chemist Di-Jia Liu looks on.
In the journal Science, Argonne chemists have identified a new catalyst that maximizes the effectiveness of platinum.
Platinum is a precious metal more rare than silver or gold. Renowned in the fuel cell community for its effectiveness in converting hydrogen and oxygen into water and
PLANO, TX – Rutronik, Inc. has announced the availability of Osram’s OSLON Square Series LEDs, a family of compact high-power LEDs that deliver superior performance in a wide range of high-density lighting applications.

Today’s hybrid and fully electric vehicles (EVs) are still in the early stages of the iterative process of innovation. Several generations of hybrid vehicles have been introduced to market and improved through a combination of technology advances and user feedback. A number of vendors now market competent

ROHM has recently launched the BD9S series of secondary synchronous Buck DC/DC converters qualified to AEC-Q100 for automotive applications. These offer high reliability and low power consumption in a compact form factor. This makes them very suitable for applications like radars, cameras and sensors which can
For years, the adoption of electric vehicles (EVs) has been marred by a slow diffusion of innovation among consumers. Probably the most obvious problem is that buyers have been apprehensive of the high initial cost of buying EVs, as well as the total cost of owning an electric vehicle over the course of its

With the very recent reassertion by scientists that the current trajectory for reducing the rate of global temperature increases is simply not good enough, there is now even greater pressure to reduce vehicle emissions of CO2 gasses. The best way of achieving this is through a reduction of the average

Teams from the accelerator physics and the SRF groups at HZB are developing a superconducting linear accelerator featuring energy recovery (Energy Recovery Linac) as part of the bERLinPro project. It accelerates an intense electron beam that can then be used for various applications - such as generating brilliant
VALENCIA, CA - H2scan announced the Gen 5 System, a first of its kind hydrogen sensor package that offers the high accuracy, small size, and low cost needed to help utilities monitor and protect their distribution transformers.

Milky, gray smog shrouds many of the valleys and lowlands of eastern China in January 2017. The orange star marks the location of Beijing.
The air in Beijing is often very bad. The city sinks under a brown cover made of exhaust gases from industry, cars and coal fires, which blow a lot of harmful particulate matter, soot, sulfur dioxide and nitrogen oxides into the air.
The dirty air causes massive damage to human health. According to
Principal investigator Subramanian Sankaranarayanan (left), and co-principal investigators Mathew Cherukara (center), Henry Chan (right) and Badri Narayanan (not pictured) are developing a new machine learning based software that will enable industry to more quickly and efficiently perform the molecular dynamics simulations they need to vet the performance of new materials for their products.
Discovering and designing new materials is frequently an expensive and time-intensive process. To speed it up and create new materials for everything from aeronautics to wind turbines, scientists have begun to rely on complex modeling and simulation platforms.

Researchers have moved a step closer to harnessing fusion energy by showing how imaging enables better testing of components for devices.
Harnessing nuclear fusion, which powers the sun and stars, to help meet earth's energy needs, is a step closer after researchers showed that using two types of imaging can help them assess the safety and reliability of parts used in a fusion energy device.

GOLETA, Calif. — Transphorm Inc., along with solar energy innovator Inergy and design partner Telcodium Inc., announced that the upcoming Inergy Kodiak Extreme uses high-voltage GaN to reimagine what’s possible
NUST MISIS scientists together with their colleagues from the Central Metallurgical R&D Institute (Cairo, Egypt) have developed a composite material which will extend the life of solar towers -- installations for collecting Solar thermal energy -- from 2-3 to 5 years. The research article has been published in the Renewable Energy journal.
Today, solar power plants (SPP) are becoming increasingly popular, making it possible to collect and process solar energy on an industrial scale. So-called solar towers are among the most promising types of SPPs. This is a special structure that is a high tower with a water tank and a turbine system inside.
(Left to right) University of Utah electrical and computer engineering assistant professor Sriram Krishnamoorthy, associate professor Mike Scarpulla, and assistant professor Berardi Sensale-Rodriguez have received a $1.88 million grant to study the properties of gallium oxide as a semiconductor for more efficient power converters. The material could prove to be much more efficient, losing less heat and providing longer power to devices such as drones or all-electric planes, trains and buses.
Electricity as a form of energy is not exactly efficient because much of it is lost as heat. Or as University of Utah electrical and computer engineering associate professor Mike Scarpulla says: "Heat is the universe's garbage can for energy."
