Engineers have developed a novel method for producing clean hydrogen, which could prove essential to weaning society off of fossil fuels and their environmental implications.

Physicists and engineers have unveiled a robust new method for arranging metal nanoparticles in geometric patterns that can act as optical processors that transform incoming light signals into output of a different color.

Engineers have used miniaturized electronics to measure the activity of individual ion-channel proteins with temporal resolution as fine as one microsecond, producing the fastest recordings of single ion channels ever performed. They designed a custom integrated circuit to perform these measurements, in which an artificial cell membrane and ion channel are attached directly to the surface of the amplifier chip.

A comprehensive study into the potential for compressed air energy storage in the Pacific Northwest has identified two locations in Washington state that could store enough Northwest wind energy combined to power about 85,000 homes each month.

Researchers have engineered a strain of electricity-producing bacteria that can grow using hydrogen gas as its sole electron donor and carbon dioxide as its sole source of carbon.

Researchers have created the first fully integrated artificial photosynthesis nanosystem. While "artificial leaf" is the popular term for such a system, the key to this success was an "artificial forest."

The type of sensors that pick up the rhythm of a beating heart in implanted cardiac defibrillators and pacemakers are vulnerable to tampering, according to a new study conducted in controlled laboratory conditions.

Researchers have published new insights into how materials transfer heat, which could lead eventually to smaller, more powerful electronic devices.

Chances are you know how many miles your car logs for each gallon or tankful of gas, but you probably have only a foggy idea of how much energy your house consumes, even though home energy expenditures often account for a larger share of the household budget.

Scientists have directly observed a rare quantum effect that produces a repeating butterfly-shaped energy spectrum, confirming the longstanding prediction of this quantum fractal energy structure called Hofstadter's butterfly.

New hardware could lead to wireless devices that identify and exploit unused transmission frequencies, using radio spectrum much more efficiently.

A group of scientists aims to store electricity at the bottom of the sea. The energy will be stored with the help of high water pressure.

Nanotubes are stronger than steel and smaller than any element of silicon-based electronics. They can potentially process information faster while using less energy. The challenge has been figuring out how to incorporate these properties into useful electronic devices. Now scientists have discovered that by adding ionic liquid -- a kind of liquid salt -- they can modify the optical transparency of single-walled carbon nanotube films in a controlled pattern.

A truss design devised to help workers process space shuttles continues to find new uses as a space shuttle engineer-turned-entrepreneur adapts it to everything from a solar-powered electric generator to a mobile cellphone tower.

The commercial application of MEMS, or micro-electro-mechanical systems, will receive a major boost today following the presentation of a brand new way to accurately measure the power requirements and outputs of all existing and future devices.

Physicists have uncovered how energy is released and dispersed in magnetic materials in a process akin to the spread of forest fires, a finding that has the potential to deepen our understanding of self-sustained chemical reactions.

Researchers are helping develop a new generation of photovoltaic cells that produce more power and cost less to manufacture than what's available today.

This focuses on an ultra-precise method for doping the tiny semiconductors produces vivid hues.

Using liquid hydrogen fuel stored in a new NRL-developed cryogenic fuel storage tank, the flight shatters the previous 26-hour record set by the UAV in 2009.

The sun provides the most abundant source of energy on the planet. However, only a tiny fraction of the solar radiation on Earth is converted into useful energy.
