RMI updates the Digital Picture Frame

RMI updates the Digital Picture Frame
The Digital Picture Frame market is booming, and what used to be a handy electronic device for viewing photos is slowly becoming an all-out Home Media Player.

This is what RMI is doing as their new application offers video streaming, wireless connectivity, as well as increased on-demand content to any digital photo frame. This application is possible through the use of the RMI Alchemy Au1200 series of connected media processors.

So, what is already a booming market is going to boom like an atomic bomb. No word when these new applications will be implemented, but you can expect a price increase on these new and improved digital frames.

First beam for Large Hadron Collider

First beam for Large Hadron Collider
An international collaboration of researchers today sent the first beam of protons zooming at nearly the speed of light around the 17-mile-long underground circular path of the Large Hadron Collider (LHC), the world's most powerful particle accelerator, located at the CERN laboratory near Geneva, Switzerland.

The researchers also accelerated a second beam of protons through the path in the opposite direction, the goal being head-on collisions of protons that can offer clues to the origin of mass and new forces and particles in the universe. The second beam made one turn around the LHC.

Celebrations across the United States and around the world mark the LHC's first circulating beams, an occasion more than 15 years in the making. An estimated 10,000 people from 60 countries have helped design and build the accelerator and its massive particle detectors, including more than 1,700 scientists, engineers, students and technicians from 94 U.S. universities and laboratories supported by the U.S. Department of Energy Office of Science and the National Science Foundation.

UCR faculty Robert Clare, John Ellison, J. William Gary, Gail Hanson and Stephen Wimpenny, along with postdoctoral researchers and graduate students are involved in the LHC's Compact Muon Solenoid (CMS) experiment, a large particle-capturing detector whose discoveries are expected to help answer questions such as: Are there undiscovered principles of nature? What is the origin of mass? Do extra dimensions exist? What is dark matter? How can we solve the mystery of dark energy? And how did the universe come to be?........

UC Santa Barbara has key role in Large Hadron Collider project

UC Santa Barbara has key role in Large Hadron Collider project
Engineer Dean White holds one of the detectors assembled at UCSB.
(Santa Barbara, Calif.) -- Earlier today, some 300 feet below the Earth's surface, in a circular tunnel so extensive that it travels from Switzerland into France and back again, researchers at the Large Hadron Collider (LHC) at the European Organization for Nuclear Research (CERN) in Geneva fired the first beams of protons that they hope will eventually produce history-making science.

A contingent of more than 40 faculty members, graduate students, postdoctoral researchers, engineers, technicians, and undergraduates from UC Santa Barbara have worked for eight years to help construct the experimental apparatus. The UCSB group is part of an international effort that is now embarking on a 15-year quest to try to answer fundamental questions about the universe.

The startup of the LHC marked a milestone for the UCSB particle physics program. The group has played a key role in constructing one of four major experiments now in place the Compact Muon Solenoid (CMS), a complex array of instruments for detecting subatomic particles. The device weighs more than 12,000 tons and is as tall as a four-story building.

UCSB's team is led by four members of its experimental high-energy physics faculty. Professor Joseph Incandela has been in Switzerland for the past year, shepherding the CMS experiment as deputy physics coordinator. Shuttling back and forth between Santa Barbara and Switzerland have been professors Claudio Campagnari, Jeffrey Richman, and David Stuart. The faculty members are unanimous in their praise for CERN's monumental effort in building the LHC, the world's largest particle accelerator.........

Mobile microwave for your car

Mobile microwave for your car
I had to think for a few minutes to imagine a reason to own this mobile microwave, even though I''ve often thought that a car refrigerator would be handy for cold drinks on the road. I suppose a microwave in the car could be useful if you''re someone who regularly takes long road trips and would rather heat up your own homemade lasagna than eat rest stop fare. Or if you''re a huge picnic fanatic who has to have food served really, really hot, which can''t be achieved with silly little thermoses. Or you want to make your own hot, organic popcorn for the movie theatre minutes before you go in.

You power it through your 12V cigarette lighter socket (produces 175W of power) or directly from your car battery (produces 660W). This little novelty appliance is now on sale at UK store Maplin for 80GBP, (about $149).

China's Dangerous Web Domains

China's Dangerous Web Domains
A recent report by antivirus software vendor McAfee Inc. has found that some of the most dangerous domains on the Internet are in China. That may not be good for companies setting up Internet-based business there.

In an article on the report, Associated Press Technology Writer Jordan Robertson this:McAfee found the most dangerous domains to navigate to are ".hk" (Hong Kong), ".cn" (China) and ".info" (information).

Of all ".hk" sites McAfee tested, it flagged 19.2 percent as dangerous or potentially dangerous to visitors; it flagged 11.8 percent of ".cn" sites and 11.7 percent of ".info" sites that way.While the "cn" and "hk" domains get registered in China, the servers using them can be anywhere.

The "ro" (Romania) and "ru" (Russia) domains were also rated as high risk.

Porous Nanostructures For Better Fuel Cells

Porous Nanostructures For Better Fuel Cells
Computer simulation, left, shows how platinum nanoparticles will fuse into a structure with tiny pores after the polymers that guide them into position are removed. Right, electron microscope photo of the actual structure.
For 5,000 years or so, the only way to shape metal has been to "heat and beat." Even in modern nanotechnology, working with metals involves carving with electron beams or etching with acid.

Now, Cornell scientists have developed a method to self-assemble metals into complex nanostructures. Applications include making more efficient and cheaper catalysts for fuel cells and industrial processes and creating microstructured surfaces to make new types of conductors that would carry more information across microchips than conventional wires do.

The method involves coating metal nanoparticles -- about 2 nanometers (nm) in diameter -- with an organic material known as a ligand that allows the particles to be dissolved in a liquid, then mixed with a block co-polymer (a material made up of two different chemicals whose molecules link together to solidify in a predictable pattern). When the polymer and ligand are removed, the metal particles fuse into a solid metal structure.

"The polymer community has tried to do this for 20 years," said Ulrich Wiesner, Cornell professor of materials science and engineering, who, with colleagues, reports on the new method in the June 27 issue of the journal Science. "But metals have a tendency to cluster into uncontrolled structures. The new thing we have added is the ligand, which creates high solubility in an organic solvent and allows the particles to flow even at high density".........

Standards Set for Energy-Conserving LED Lighting

Standards Set for Energy-Conserving LED Lighting
These solid-state lights are powered by energy-efficient light emitting diodes and are among the first ones of a new generation expected to cut energy needed for lighting by 50 percent by 2027.
Researchers at the National Institute of Standards and Technology (NIST), in cooperation with national standards organizations, have taken the lead in developing the first two standards for solid-state lighting in the United States. This new generation lighting technology uses light-emitting diodes (LEDs) instead of incandescent filaments or fluorescent tubes to produce illumination that cuts energy consumption significantly.

Standards are important to ensure that products will have high quality and their performance will be specified uniformly for commerce and trade. These standards-the most recent of which published last month-detail the color specifications of LED lamps and LED light fixtures, and the test methods that manufacturers should use when testing these solid-state lighting products for total light output, energy consumption and chromaticity, or color quality.

Solid-state lighting is expected to significantly reduce the amount of energy needed for general lighting, including residential, commercial and street lighting. "Lighting," explains NIST scientist Yoshi Ohno, "uses 22 percent of the electricity and 8 percent of the total energy spent in the country, so the energy savings in lighting will have a huge impact".

Solid-state lighting is expected to be twice as energy efficient as fluorescent lamps and 10 times more efficient than incandescent lamps, eventhough the current products are still at their early stages. Ohno chaired the task groups that developed these new standards.........

Discovery could enable development of faster computers

Discovery could enable development of faster computers
Sketch of a ferromagnet/semiconductor structure. When the MgO interface is very thin, spin up electrons, represented in this image with an arrow to the right, are reflected back to the semiconductor. At an intermediate thickness of the interface, spin down electrons are reflected back to the semiconductor, resulting in a "spin reversal" that can be used to control current flow.

Physicists at UC Riverside have made an accidental discovery in the lab that has potential to change how information in computers can be transported or stored. Dependent on the "spin" of electrons, a property electrons possess that makes them behave like tiny magnets, the discovery could help in the development of spin-based semiconductor technology such as ultrahigh-speed computers.

The researchers were experimenting with ferromagnet/semiconductor (FM/SC) structures, which are key building blocks for semiconductor spintronic devices (microelectronic devices that perform logic operations using the spin of electrons). The FM/SC structure is sandwich-like in appearance, with the ferromagnet and semiconductor serving as microscopically thin slices between which lies a thinner still insulator made of a few atomic layers of magnesium oxide (MgO).

The researchers found that by simply altering the thickness of the MgO interface they were able to control which kinds of electrons, identified by spin, traveled from the semiconductor, through the interface, to the ferromagnet.

Study results appear in the June 13 issue of Physical Review Letters

Experimental results:

The spin of an electron is represented by a vector, pointing up for an Earth-like west-to-east spin; and down for an east-to-west spin.........

Tiny refrigerator taking shape to cool future computers

Tiny refrigerator taking shape to cool future computers
Miniature refrigeration system
Researchers at Purdue University are developing a miniature refrigeration system small enough to fit inside laptops and personal computers, a cooling technology that would boost performance while shrinking the size of computers.

Unlike conventional cooling systems, which use a fan to circulate air through finned devices called heat sinks attached to computer chips, miniature refrigeration would dramatically increase how much heat could be removed, said Suresh Garimella, the R. Eugene and Susie E. Goodson Professor of Mechanical Engineering.

The Purdue research focuses on learning how to design miniature components called compressors and evaporators, which are critical for refrigeration systems. The researchers developed an analytical model for designing tiny compressors that pump refrigerants using penny-size diaphragms and validated the model with experimental data. The elastic membranes are made of ultra-thin sheets of a plastic called polyimide and coated with an electrically conducting metallic layer. The metal layer allows the diaphragm to be moved back and forth to produce a pumping action using electrical charges, or "electrostatic diaphragm compression".

In related research, the engineers are among the first to precisely measure how a refrigerant boils and vaporizes inside tiny "microchannels" in an evaporator and determine how to vary this boiling rate for maximum chip cooling.........
