To develop ever-smaller chips that consume less. These are the indispensable requirements of the current market for portable applications such as mobile telephone technology and biomedical systems, obtaining correct and trouble-free operation of the devices over the maximum possible duration of time. One of the techniques which, in fact, can be used for the development of this type of reduced-size, low-consumption microchip is one analysed by Carlos Aristóteles de la Cruz in his PhD defended at t
Another important step towards realizing the promise of lightning fast photonic technology has been taken by scientists with the U.S. Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab) and the University of California at Berkeley. Researchers have demonstrated that semiconductor nanoribbons, single crystals measuring tens of hundreds of microns in length, but only a few hundred or less nanometers in width and thickness (about one ten-millionth of an inch), can serve as “wa
A common mineral can remove carbon dioxide from combustion gases, but in its natural state, it is glacially slow. Now, a team of Penn State researchers is changing serpentine so that it sequesters the carbon dioxide from fossil fuel burning in hours, not eons.
“Serpentine naturally sequesters carbon dioxide over geologic time, but it is too slow to help us,” says Dr. M. Mercedes Maroto-Valer, assistant professor of energy and geo-environmental engineering and program coordinator fo
Vulnerabilities inadvertently built into the U.S. power grid, which is one of the most complex systems ever constructed, have been identified by a research team lead by Reka Albert, assistant professor of physics at Penn State. The teams topological analysis of the grid structure reveals that, although the system has been designed to withstand the random loss of generators or substations, its integrity may depend on protecting a few key elements.
“Our analysis indicates that
Austrian-German research team demonstrates for the first time an attosecond “oscilloscope” rendering the hyper-fast field oscillations of visible light
The human eye can detect changes in the intensity of light, not however the wavelength because light oscillates too fast (approximately 1000 trillion times per second). An international collaboration led by Ferenc Krausz and made up of researchers from the Vienna University of Technology, the Max-Planck-Institute for Quantum Opt
Most of the energy that goes into building U.S. homes is consumed – not by the power tools, welding and trucking during construction – but during the manufacture of the building materials, according to a comprehensive life-cycle assessment comparing typical wood-, steel- and concrete-frame homes.
Using the least energy-intensive building materials – and taking steps toward such things as recycling and reusing more building materials – makes sense considering the nation’s energy conc
