A new way to measure energy in microscopic machines

What drives cells to live and engines to move? It all comes down to a quantity that scientists call "free energy," essentially the energy that can be extracted from any system to perform useful work. Without this available ...

Researchers report new oxyfluoride compound for photocatalysis

Over the last decade, research has intensified to develop efficient, manmade photocatalysts that work under visible light—an important target for renewable energy systems. Scientists in Japan have now shown that an oxyfluoride ...

Vermont reduces incentives for renewable energy program

Vermont regulators are reducing the financial incentives for electric customers who install renewable energy systems such as solar panels and get a credit on their electric bills for providing power to the grid.

Designing urban energy systems based on the urban climate

As cities grow at an ever-faster pace, concerns about global warming rise and fossil fuels become increasingly scarce, cities will have to adopt more sustainable energy solutions. EPFL researchers have developed a model that ...

Team develops sodium ion batteries using copper sulfide

A KAIST research team recently developed sodium ion batteries using copper sulfide anode. This finding will contribute to advancing the commercialization of sodium ion batteries (SIBs) and reducing the production cost of ...

When nuclei catch up with electrons

In an attosecond study of the H2 molecule, physicists at ETH Zurich found that for light atomic nuclei, as contained in most organic and biological molecules, the correlation between electronic and nuclear motions cannot ...
