$43 Million for Transformational Storage Projects to Advance Electric Vehicle and Grid Technologies
2 August 2012 | announcement
"The Department of Energy today announced that 19 transformative new projects will receive a total of $43 million in funding from the Department’s Advanced Research Projects Agency-Energy (ARPA-E) to leverage the nation’s brightest scientists, engineers and entrepreneurs to develop breakthrough energy storage technologies and support promising small businesses..."

Advanced Management And Protection Of Energy-Storage Devices (AMPED)
- Lead organization: PARC
- Description: Smart Embedded Network of Sensors with Optical Readout (SENSOR). Palo Alto Research Center will develop new fiber optic sensors that are inserted into battery packs to monitor and measure batteries during charge and discharge cycles. These compact fiber optical sensors will measure the battery’s health while in use to avoid degradation and failure.
- Funding: $4,018,960
ARPA-E awards $43M to 19 energy storage projects to advance electric vehicle and grid technologies
2 August 2012 | Green Car Congress
"The US Department of Energy’s Advanced Research Projects Agency-Energy (ARPA-E) has selected 19 new projects to receive a total of $43 million to develop breakthrough energy storage technologies and support promising small businesses...
Unlike other Department of Energy efforts to push the frontiers of battery chemistry, AMPED is focused on maximizing the potential of existing battery chemistries. These innovations are intended to help reduce costs and improve the performance of next generation storage technologies, which could be applied in both plug-in electric and hybrid-electric vehicles."
PARC Orders Aixtron MOCVD System For Lasers and LEDs
After delivery in the second quarter of 2011, the system will be used for the epitaxial growth of InGaAlN LEDs, laser diodes, and electronic devices.

by company release
"...the system will be used for the epitaxial growth of InGaAlN LEDs, laser diodes, and electronic devices. A local Aixtron support team will commission the new reactor within a specially dedicated facility in PARC's electronic materials and devices research division...
'We will be able to develop new processes in a commercial reactor that are compatible with a prospective scale-up to full production scale in due course. Working closely with the experienced Aixtron support team, our group expects to, for example, quickly optimize conditions for growth of GaN alloys with a high percentage of Al as required for deep-UV optical emitting devices.'"
Building a handheld HIV detector
Researchers race to bring cheap HIV testing to rural regions of developing countries.
1 April 2010 | Inside Science
by Devin Powell
Researchers at PARC "have shrunk the laser technology inside large laboratory machines down to about the size of an iPod. Their cheap, handheld device promises to provide an immune system check-up on the spot and in less than 10 minutes. The technology analyzes a small sample of blood drawn by a finger prick. 'The quality of their test is great,' said researcher Bernhard Weigl of PATH, a non-profit reviewing a variety of CD4 testing technologies. 'If you look at their graph, it pretty much looked like the graph you would get from a big instrument.' PARC's prototype cost about $250 to build, a hundred times cheaper than the large flow cytometers currently in use."
Dowa presents 320–350nm UV LED samples
17 March 2010 | Semiconductor Today
by Mike Cooke
"The company is presently offering prototype samples emitting at wavelengths of 320–350nm with 1.4mW output power at 20mA current and is seeking to start mass production. The nitride semiconductor epitaxial layers are grown using technology developed by PARC in the USA and Japan’s RIKEN. Dowa sees opportunities for UV LED application in resin curing, adhesion, drying, medical treatment, analysis, photo catalysis, water purification and sterilization. A particular attraction of LEDs is their more environment-friendly character when compared with UV mercury lamps. The economic factor of longer life is also attractive."
Dowa Electronics Materials Co., Ltd., "has successfully developed practical applications for a deep ultraviolet LED that generates shorter wavelengths than the ultraviolet LEDs currently available on the market...The company created an LED with the world's highest output in wavelengths by combining the AIN template (high-quality AIN film growing on the sapphire substrate) that it has and an ultraviolet LED epi growth technology introduced from [the] PARC and RIKEN and by applying the technology."
PHOTONIC FRONTIERS: SEMICONDUCTOR UV LASERS
Materials are a tough challenge for ultraviolet diode lasers
1 December 2008 | Laser Focus World
by Jeff Hecht
"'A lot of progress is being made in deep-ultraviolet LEDs,' says Noble Johnson of the Palo Alto Research Center. Quantum efficiency at the shorter wavelengths is limited, but LEDs don't require the high drive currents that make materials problems acute in UV lasers. Johnson [is] among researchers who have turned to UV LEDs as a more tractable problem."
