The pinhole camera, a technique known since ancient times, has inspired a futuristic technology for lensless, three-dimensional imaging. Working at both the Advanced Light Source at the U.S. Department of Energy's Lawrence Berkeley National Laboratory, and at FLASH, the free-electron laser in Hamburg, Germany, an international group of scientists has produced two of the brightest, sharpest x-ray holograms of microscopic objects ever made, thousands of times more efficiently than previous x-ray-holographic methods.
The Advanced Energy Consortium, a research consortium managed by the Bureau of Economic Geology at The University of Texas at Austin's Jackson School of Geosciences, has issued a request for proposals to develop micro- and nanoscale technology for enhanced reservoir characterization and hydrocarbon detection in conventional oil and gas reservoirs with the ultimate goal of increasing hydrocarbon recovery from known fields.
With the support of Chinese government, CAS has been undertaking national mega-science projects in line with both the requirements of the national socio-economic development and cutting-edge development of science and technology in the world.
A multi-institutional team of scientists has used beamline 9.0.1 at the Advanced Light Source to perform high-resolution x?]ray diffraction imaging of an aerogel for the first time, revealing its nanoscale three-dimensional bulk lattice structure down to features measured in nanometers.
A Michigan State University researcher and his students have developed a nanomaterial that makes plastic stiffer, lighter and stronger and could result in more fuel-efficient airplanes and cars as well as more durable medical and sports equipment.
Physicists at the University of Pennsylvania have characterized an aspect of graphene film behavior by measuring the way it conducts electricity on a substrate. This milestone advances the potential application of graphene, the ultra-thin, single-atom thick carbon sheets that conduct electricity faster and more efficiently than silicon, the current material of choice for transistor fabrication.
Physicists at the University of Pennsylvania have demonstrated a new method by which few layer graphene can be etched along flawless, crystallographic axes by using thermally activated nanoparticles, a technique that results in atomically precise, macroscopic length ribbons of graphene.
