New trigger for self-powered mechanical movement

01-Mar-2016

A new way to use the chemical reactions of certain enzymes to trigger self-powered mechanical movement has been developed by a team of researchers at Penn State University and the University of Pittsburgh. "These pumps provide precise control over flow rate without the aid of an external power ...

Researchers mine information from next-generation subsurface flow simulations

11-Sep-2015

Ask a geoscientist how he or she feels about the phrase, "out of sight, out of mind," and you likely will meet some serious resistance. The scientist likely would explain that learning how different materials interact with one another below the Earth's surface is of the utmost importance. Indeed, ...

Stop hyperventilating, say energy efficiency researchers

Customizing fan speed to actual need would slash energy demand 18 percent

20-Jun-2013

A single advanced building control now in development could slash 18 percent – tens of thousands of dollars – off the overall annual energy bill of the average large office building, with no loss of comfort, according to a report by researchers at the Department of Energy's Pacific Northwest ...

Pyroelectric nanogenerator charges Li-ion battery with harvested energy

26-Nov-2012

The idea of harvesting ambient energy from the environment that would otherwise not be purposefully used is, in theory, a great way to produce green, renewable energy. But the biggest problem in this fairly new area of research is that scientists have yet to find a method that can harvest very ...

Scientists produce transparent, light-harvesting material

08-Nov-2010

Scientists at the U.S. Department of Energy's Los Alamos National Laboratory and Brookhaven National Laboratory have fabricated transparent thin films capable of absorbing light and generating electric charge over a relatively large area. The material, described in the journal Chemistry of ...

Microbes may consume far more oil-spill waste than earlier thought

Study near Gulf of Mexico spill site finds surprisingly high methane uptake by microbes

22-Oct-2010

Microbes living at the bottom of the Gulf of Mexico may consume far more of the gaseous waste from the Deepwater Horizon oil spill than previously thought, according to research carried out within 100 miles of the spill site. A paper on that research, conducted before the Deepwater Horizon rig ...

MRI zooms in on microscopic flow

12-Oct-2010

"Better and faster results!" is the clarion call for scientists and engineers to continually strive to improve their research tools. Of the tools used to study material structures at the atomic and molecular scales, there is none finer than Nuclear Magnetic Resonance (NMR) spectroscopy and its ...

Fuel cells in operation: A closer look

11-Oct-2010

Measuring a fuel cell's overall performance is relatively easy, but measuring its components individually as they work together is a challenge. That's because one of the best experimental techniques for investigating the details of an electrochemical device while it's operating is x-ray ...

Nano antenna concentrates light

Intensity increases 1,000-fold in Rice lab's experiment

23-Sep-2010

Everybody who's ever used a TV, radio or cell phone knows what an antenna does: It captures the aerial signals that make those devices practical. A lab at Rice University has built an antenna that captures light in the same way, at a small scale that has big potential. Condensed matter physicist ...

Electron switch between molecules points way to new high-powered organic batteries

17-Sep-2010

The development of new organic batteries—lightweight energy storage devices that work without the need for toxic heavy metals—has a brighter future now that chemists have discovered a new way to pass electrons back and forth between two molecules. The research is also a necessary step toward ...
