While many building infrastructures are built with materials to help absorb or reflect sound, mechanisms to truly control the direction of sound waves are still in their infancy. However, researchers at the California Institute of Technology have now created the first tunable acoustic diode—a device that allows acoustic information to travel only in one direction, at controllable frequencies.
Taking advantage of the unique properties of zinc oxide nanowires, researchers have demonstrated a new type of piezoelectric resistive switching device in which the write-read access of memory cells is controlled by electromechanical modulation. Operating on flexible substrates, arrays of these devices could provide a new way to interface the mechanical actions of the biological world to conventional electronic circuitry.
Organic light emitting diode (OLED) lighting has the potential to create cheap, pleasing light in unique, flexible form factors. However, the technology is immature and costly. Lux Research reports that OLED lighting costs will drop by more than an order of magnitude over the course of this decade. But the technology will still remain uncompetitive with other lighting options, and amount to a mere $58 million market in 2020.
Shimadzu Scientific Instruments is improving the efficiency of network operations for the Nexera UHPLC and Prominence HPLC systems by enabling system control and monitoring via an iPad. When connected wirelessly to the HPLC's workstation, the iPad can simultaneously monitor and control the operating and usage conditions of multiple HPLC systems within a single network.
Because illicit whisky costs huge sums in lost revenue and threatens brand reputation, chemists have long been testing samples in the laboratory. Now, researchers in Scotland are using an optical fiber innovation in combination with infrared spectrometry to distinguish authentic and counterfeit Scotch more quickly.
On Monday, the director of the world's largest atom smasher, the Large Hadron Collider, predicted that scientists will find the long-sought Higgs boson—or rule out that it exists—by the end of 2012. The theoretical particle is the linchpin of the Standard Model of particle physics theory that explains the Big Bang.
Stanford University researchers have invented a transparent lithium-ion battery that is also highly flexible. It is comparable in cost to regular batteries on the market today, with great potential for applications in consumer electronics.
Scientists at the U.S. Department of Energy's Brookhaven National Laboratory have developed a computational model for analyzing the metabolic processes in rapeseed plants—particularly those related to the production of oils in their seeds. Their goal is to find ways to optimize the production of plant oils that have widespread potential as renewable resources for fuel and industrial chemicals.
Researchers Zhili Feng, Alan Frederic, and Stan David in Oak Ridge National Laboratory's Materials S&T Division have made significant progress toward a new metal processing technique, called friction-stir extrusion, that could represent a major advance in converting recyclable materials to useful products.
Looking to improve upon current methods of imaging, researchers from the California Institute of Technology have developed a novel approach that could redefine optical imaging of live biological samples by simultaneously achieving high resolution, high penetration depth (for seeing deep inside 3D samples), and high imaging speed.
REO offers custom prism assemblies that enable construction of compact beam multiplexing systems. The assemblies feature low transmitted wavefront distortion values (as low as ?/10 at 633 nm), beam deviation tolerance in the arc second range, and the capability for precise control of output beam phase relationships.
Suited for the automotive, plastics, and chemical industries, Omega Engineering’s CL510A series of RTD simulators check and calibrate RTD instruments with high accuracy.
Flying in the face of years of scientific belief, University of Illinois researchers have demonstrated that sugar doesn't melt, it decomposes.The finding should help food scientist create yummier flavors and better textures, and even help the pharmaceutical industry provide a better “spoonful of sugar”.
An artificial lung built by researchers at Case Western has reached efficiencies akin to the genuine organ, using air--not pure oxygen as current man-made lungs require--for the source of the essential element. The developers are targeting clinical trials within the decade.
Gale Crater was chosen as the target for the $2.5 billion Mars Science Laboratory mission after an extensive review of dozens of potential sites. NASA chose this site because they believe they have located the boundary where life may have sprung up and where it may have been extinguished.
