Using enhanced halide perovskite in place of silicon could produce less expensive devices that stand up better to light and heat.

By wrapping platinum-alloy crystals in tiny graphene “nanopockets,” scientists generated far more catalytic activity and power than expected.

Researchers are lending their expertise to help make sure everyone in Los Angeles can benefit from the efforts.

Researchers have devised a method for more quickly predicting the performance of potential catalysts in fuel cells.

Professor Ted Parson will serve as senior advisor to the commission.

“Not all energy-efficient upgrades or programs are the same,” said Magali Delmas, a UCLA environmental economist and co-author of the paper.

A new pilot program aims to help low-income, first-generation and historically underrepresented students pursue graduate studies and research careers.

UCLA researchers and colleagues demonstrate how the transition could improve public health and save money.

Promotional messages about saving money on electricity bills or earning other financial rewards motivated homeowners to conserve.

A UCLA study shows that 30% of residents now can choose cleaner power from community choice aggregators.

Without careful planning, the shift to green power could cost more and strain the state’s grid.

Affluent neighborhoods use more energy and reap greater benefits from government incentive programs, a new UCLA study shows.

The key is a new catalyst: copper with a few atoms of the precious metal ruthenium.

Thanks to an advance by UCLA engineers, the two-wing structure could soon be used to make windmills that harvest energy more efficiently.

In this role, Hoek will provide leadership and grow partnerships with faculty and stakeholders to improve ecosystem health in Los Angeles.

A version of the technology, set up on the roof of a home, could provide enough power overnight to charge a cell phone or to light a room with LED bulbs.

A UCLA study reveals how the United States can maximize the benefits of waste-derived fuels.

Free online tool updated to include solar capacity and six more years of data, as California aims for 100% renewable energy.

In tests, perovskite-based cells made with the same chemical found in coffee maintained their power conversion efficiency for several weeks longer than those without it.

Without changes being made by 2040, the report found, certain locales would be guaranteed to experience power failures at the hottest times of the year.

In tests at the U.S. Department of Energy’s National Renewable Energy Laboratory, the device converted 22.4 percent of the incoming energy from the sun, a record for that type of cell.

The advance could revolutionize thermal management designs for computer processors and other electronics.

The Synthetic Control Across Length-scales for Advancing Rechargeables center will help accelerate research on new types of chemistry and materials that can help improve batteries’ capacity, stability and safety.

In experiments the device produced 30 percent better capacitance — the measure of a device’s ability to store an electric charge — for its mass compared to the best available electrode made from similar materials.

UCLA is already leading the way through its Sustainable LA Grand Challenge.
