This is a schematic of a solar-powered electrolysis cell which converts carbon dioxide into hydrocarbon and oxygenate products with an efficiency far higher than natural photosynthesis. Power-matching electronics allow the system to operate over a range of sun conditions.

Engineers have developed printable metal tags that could be attached to everyday objects and turn them into "smart" Internet of Things devices.
The metal tags are made from patterns of copper foil printed onto thin, flexible, paper-like substrates and are...
Imagine not having to charge your phone or laptop for weeks. That is the dream of researchers looking into alternative batteries that go beyond the current lithium-ion versions popular today. Now, in a new study appearing in the journal...
Diamond is well-known as the strongest of all natural materials, and with that strength comes another tightly linked property: brittleness. But now, an international team of researchers from MIT, Hong Kong, Singapore, and Korea has found that when grown...
Experimenting on mice with a genetic change similar to that found in people with a rare inherited disease called Kabuki syndrome, Johns Hopkins scientists report that a very low-carbohydrate diet can "open up" DNA and improve mental function.
Along with...
Solar power accounts for less than 2 percent of U.S. electricity but could make up more than that if the cost of electricity generation and energy storage for use on cloudy days and at nighttime were cheaper.
A Purdue University-led...

A new design for solar cells that uses inexpensive, commonly available materials could rival and even outperform conventional cells made...
The STAR collaboration's exploration of the "nuclear phase diagram" shows signs of a sharp border--a first-order phase transition--between the hadrons that make up ordinary atomic nuclei and the quark-gluon plasma (QGP) of the early universe when the QGP is...
This illustration shows the structure of 16 molecules that were studied while bound to metal-organic frameworks (MOFs) that exhibit handedness. The frameworks stabilized the molecules for study with X-rays.Credit: S. Lee, E. Kapustin, O. Yaghi/Berkeley Lab and UC Berkeley

A new concept for a flow battery functions like an old hourglass or egg timer, with particles (in this case carried as a slurry) flowing through a narrow opening from one tank to another. The flow can then be...
