(PhysOrg.com) -- Lara Estroff and colleagues have taken a deep, detailed look at the way lab-created calcite crystals, similar to those found in nature, grow in tandem with proteins and other large molecules. http://www.physorg.com/news178823885.html Chemistry Mon, 30 Nov 2009 17:19:17 EST news178823885 (PhysOrg.com) -- Researchers from the NSLS and Science Applications International Corporation (SAIC) have demonstrated a technique that could be used to significantly improve the quantity and quality of light produced from a free-electron laser (FEL) - a source that provides pulses of light that can be 1,000 times shorter than those at conventional storage ring light sources. http://www.physorg.com/news177952043.html Physics Fri, 20 Nov 2009 15:24:58 EST news177952043 (PhysOrg.com) -- University of Toronto researchers continue to uncover the mysteries of space. But even the best astronauts in the world are stymied if the spaceship doesn't launch. When the countdown stops, it is often because a hydrogen leak has been detected. One small malfunction in the sensing device can mean millions of dollars lost. http://www.physorg.com/news177096977.html Nanotechnology Tue, 10 Nov 2009 19:10:02 EST news177096977 Particle accelerators are among the largest and most expensive scientific instruments. Thirty years ago, theorists John Dawson and Toshiki Tajima proposed an idea for making them thousands of times smaller: surf the particles on plasma waves driven by short intense laser pulses. Since plasmas are free of the damage limits of conventional accelerators, much larger fields can be built up within such waves, enabling much smaller accelerators. http://www.physorg.com/news176402686.html Physics Mon, 02 Nov 2009 17:20:01 EST news176402686 (PhysOrg.com) -- An Arizona State University engineering student may have found the tiniest - yet most cleverly inventive - way to show school spirit. http://www.physorg.com/news176106977.html Technology Fri, 30 Oct 2009 08:00:01 EST news176106977 (PhysOrg.com) -- Brookhaven Lab scientists have developed a new scanning electron microscope capable of selectively imaging single atoms on a surface while simultaneously probing atoms throughout the sample?s depth. The development could greatly expand scientists? ability to understand and control chemical reactions, such as those in energy-conversion devices. http://www.physorg.com/news172746177.html Nanotechnology Mon, 21 Sep 2009 10:04:16 EST news172746177 (PhysOrg.com) -- `Most current hard x-ray interferometers are based on crystals, which require their high quality and high mechanical stability,` Anatoly Snigirev tells PhysOrg.com. `This can make x-ray interferometry quite limited. What we have done is develop a different set up that is simpler.` Snigirev is a scientist at ESRF in Grenoble France. Along with scientists at the Russian Kurchatov Research Center in Moscow, and at IMT RAS in Chernogolovka, Russia, Snigirev proposes that refractive bilenses made from silicon can be used in place of crystals. http://www.physorg.com/news169383826.html Physics Thu, 13 Aug 2009 12:06:21 EST news169383826 A new microscope that views the subatomic universe -- the first of its kind in the world -- is being built for the University of Victoria, Canada, in collaboration with Hitachi High-Technologies. http://www.physorg.com/news166981239.html Nanotechnology Thu, 16 Jul 2009 16:41:18 EST news166981239 Fast and affordable genome sequencing has moved a step closer with a new solid-state nanopore sensor being developed by researchers at the University of Illinois. http://www.physorg.com/news163160102.html Nanotechnology Tue, 02 Jun 2009 11:15:32 EST news163160102 Catalysts do function, despite the fact that not all the chemical reactions (and partial reactions) which occur are fully understood, including those which take place during the treatment of automobile exhaust. If scientists understood these processes better not only would they be able to optimize exhaust gas catalysts but also other phenomena which are observed on surfaces, for instance when molecules orient themselves in either right or left handed fashion (i.e. as an image or mirror image). Knowing this would, not least, open new avenues of development in pharmacology for the manufacturers of medicines. http://www.physorg.com/news162828115.html Nanotechnology Fri, 29 May 2009 15:02:32 EST news162828115 An oscilloscope is a device for displaying signals that are too fast to be seen by the human eye. Typically the signal consists of a voltage level that changes quickly moment by moment (over millisecond to nanosecond timescales). What is seen on the screen of the scope is a waveform whose value is graphed along the vertical axis as a function of the horizontal axis representing time. An electron beam, aimed at a phosphorescent screen, is swept horizontally providing a light-trace on the screen while, coincidentally, the instantaneous voltage of the input signal is used to deflect the electron beam up or down, creating the visible trace. http://www.physorg.com/news162582105.html Physics Tue, 26 May 2009 18:42:13 EST news162582105 (PhysOrg.com) -- The world's brightest X-ray source sprang to life last week at the U.S. Department of Energy's SLAC National Accelerator Laboratory. The Linac Coherent Light Source (LCLS) offers researchers the first-ever glimpse of high-energy or "hard" X-ray laser light produced in a laboratory. http://www.physorg.com/news159556347.html Physics Tue, 21 Apr 2009 18:12:48 EST news159556347 In 2004 Lyncean Technologies announced the construction of the Compact Light Source (CLS), a miniature synchrotron which uses inverse Compton scattering to produce high-intensity, tunable, near-monochromatic x-ray beams. The CLS was designed to bring state-of-the-art protein structure determination to the home laboratory -- but it has also promised to have a broad impact across the spectrum of x-ray science. http://www.physorg.com/news150537938.html Physics Wed, 07 Jan 2009 08:05:38 EST news150537938 (PhysOrg.com) -- In a few short months, the Linac Coherent Light Source will start operation as the world's first hard X-ray free electron laser, pushing SLAC National Accelerator Laboratory to the frontier of photon science. Using SLAC's linac to drive a free electron laser, or FEL, the LCLS will generate X-rays an eye-popping 10 billion times brighter than the current cutting-edge technology, while simultaneously providing pulses lasting less than one millionth of one billionth of a second. http://www.physorg.com/news147708604.html Physics Fri, 05 Dec 2008 14:10:04 EST news147708604
