Video of the week: Freescale delivers big power from small solar cells

By / February 18, 2009

Via CNET’s Green Tech blog, we bring you a video about some nifty power conversion technology for photovoltaic applications that Freescale Semiconductor unveiled this week at the Applied Power Electronics Conference and Exposition. This is about high efficiency, ultra-low-voltage DC-to-DC converter technology. It enables IC startup thresholds to be reduced to 0.32 V (ICs typically can’t…

New ‘domains’ for nano electronics

By / February 9, 2009

Researchers say that logic and memory functions of future electronic devices could shrink an order of magnitude (one or two nanometers, instead of tens of nanometers) if they can control domain walls, the transition zones in a material that separate regions of different magnetic, electric or other properties. And, by “control,” the researchers remarkably mean…

Video of the week – Two approaches to cloaking

By / January 21, 2009

Several research teams are actively pursuing cloaking/invisibility concepts. One of the prominent groups is at Duke University and the other is at University of California, Berkeley. The Berkeley team uses a crafted nano-prism of metamaterial atoms that has a negative refractive index for light of near-infrared wavelengths. The Duke team is also uses metamaterials, but…

Ceramics as alternative to conventional laser generation

By / January 15, 2009

Kudos to Akio Ikesue and Yan Lin Aung for their recent article in Nature Photonics. Ikesue (bias confession: he is an ACerS member) and Yan report on recent developments in the field. From their summary: The opaque and translucent cement and clay often used in tableware are not appropriate for optical applications because of the…

Creating alternating current with piezoelectrics

By / January 8, 2009

Researchers at the Georgia Institute of Technology have created a micro-scale “flexible charge pump” that produces alternating current by utilizing the piezoelectric properties of cyclically stretched and released zinc oxide wires. “The flexible charge pump offers yet another option for converting mechanical energy into electrical energy,” says project leader Zhong-Lin Wang, director of GIT’s Center…
