With its wings stretched wide to catch the sun's energy, a Swiss-made solar-powered aircraft took off from Abu Dhabi just after daybreak today in a historic first attempt to fly around the world without a drop of fossil fuel.
Green wall technology and semi-transparent solar panels have been combined to generate electrical current from a renewable source of energy both day and night. A prototype “green bus shelter” that could eventually generate enough electricity to light itself, has been built by a collaboration of university researchers and eco-companies.
Researchers wanted to find a better way to make coatings that can be painted onto surfaces to conduct electricity or convert electricity into hydrogen fuels. Instead, they found a new way to make state-of-the-art materials for energy storage using a cheap lamp from the hardware store.
Scientists at Oak Ridge National Laboratory (ORNL) have captured the first real-time nanoscale images of lithium dendrite structures known to degrade lithium-ion batteries. The ORNL team’s electron microscopy could help researchers address long-standing issues related to battery performance and safety.
Lithium-ion batteries are common in consumer electronics. Beyond consumer electronics, lithium-ion batteries have also grown in popularity for military, electric vehicle and aerospace applications. Now, researchers at Arizona State Univ. are exploring new energy storage technology that could give the battery an even longer lifecycle.
Engineers and researchers from national laboratories and universities around the country said Thursday that the U.S. needs to develop a proving ground where the latest innovations in nuclear energy can be put to the test instead of losing designs to China and other countries.
Martian colonists could use an innovative new technique to harvest energy from carbon dioxide thanks to research pioneered at Northumbria Univ. The research proposes a new kind of engine for producing energy based on the Leidenfrost effect, a phenomenon which happens when a liquid comes into near contact with a surface much hotter than its boiling point.
Trapping carbon dioxide emissions from power plants and various industries could play a significant role in reducing greenhouse gas emissions in the future. But current materials that can collect carbon dioxide have low capacities or require very high temperatures to work. Scientists are making progress toward a more efficient alternative, described in Chemistry of Materials, that could help make carbon capture less energy intensive.
Researchers with the Energy Biosciences Institute have found a way to increase the production of fuels and other chemicals from biomass fermented by yeast. By introducing new metabolic pathways into the yeast, they enable the microbes to efficiently ferment cellulose and hemicellulose, the two major families of sugar found in the plant cell wall, without the need of environmentally harsh pre-treatments or expensive enzyme cocktails.
Lawrence Livermore National Laboratory researchers have identified electrical charge-induced changes in the structure and bonding of graphitic carbon electrodes that may one day affect the way energy is stored.

The adverse effects of radiation on nuclear fuel could soon be better controlled thanks to research involving Univ. of Tennessee at Knoxville's College of Engineering. Maik Lang, an assistant nuclear engineering professor, is part of a team of researchers that has studied how specific properties of materials involved in nuclear energy production, and their performance, can change their response to radiation.
From light-up shoes to smart watches, wearable electronics are gaining traction among consumers, but these gadgets’ versatility is still held back by the stiff, short-lived batteries that are required. These limitations, however, could soon be overcome.
A new provisionally patented technology from a New Mexico State Univ. researcher could revolutionize carbon dioxide capture and have a significant impact on reducing pollution worldwide. Through research on zeolitic imidazolate frameworks, or ZIFs, the researcher synthesized a new subclass of ZIF that incorporates a ring carbonyl group in its organic structure.
Researchers at the Univ. of Houston have created a new thermoelectric material, intended to generate electric power from waste heat with greater efficiency and higher output power than currently available materials.

A new study from the National Renewable Energy Laboratory demonstrates the conversion of lignin-derived compounds to adipic acid, an important industrial dicarboxylic acid produced for its use as a precursor to nylon. The demonstration is an important step toward the goal of garnering more uses from lignin, which could be crucial for the economic success of the biofuels industry.
Lithium-sulfur batteries have been a hot topic in battery research because of their ability to produce up to 10 times more energy than conventional batteries, which means they hold great promise for applications in energy-demanding electric vehicles. However, there have been fundamental road blocks to commercializing these sulfur batteries.
Dislocations in oxides such as cerium dioxide, a solid electrolyte for fuel cells, turn out to have a property that is the opposite of what researchers had expected, according to a new analysis. Researchers had thought that a certain kind of strain would speed the transport of oxygen ions through the material, potentially leading to the much faster diffusion that is necessary in high-performance solid-oxide fuel cells.
A research partnership is reporting advances on how to make solar cells stronger, lighter, more flexible and less expensive when compared with the current silicon or germanium technology on the market.
