Novel Computer Chips Could Bridge Gap Between Computation and Storage

Software written by Jing Li, right, and her students — including Jialiang Zhang, left —allows programmers to directly use existing coding languages with the new Liquid Silicon chips. (Credit: Stephanie Precourt/UW–Madison College of Engineering) Computer chips in development at the University of Wisconsin–Madison could make future computers more efficient and powerful by combining tasks usually kept separate by design. Jing Li, an assistant professor of electrical and computer engineering at UW–Madison, is creating computer chips that can be configured to perform complex calculations and store massive amounts of information within the same integrated unit — and communicate efficiently with other chips. She calls them “liquid silicon.”

Yoon, Korea University) A new, ultrathin film that is both transparent and highly conductive to electric current has been produced by a cheap and simple method devised by an international team of nanomaterials researchers from the University of Illinois at Chicago and Korea University. The film is also bendable and stretchable, offering potential applications in roll-up touchscreen displays, wearable electronics, flexible solar cells and electronic skin.

SWaP-C and Why Your Component Partner Matters

The military is continually pushing to decrease the size, weight, power and cost (SWaP-C) of its electronics, particularly for items carried by the troops. To meet these goals, everyone involved in designing and manufacturing the device needs to work together closely to ensure maximum efficiency of every component. This makes choosing the right partner crucial. Our white paper explores why SWaP-C is so important and includes information on:

Carbon Nanofibers Synthesized on Selective Substrates for Nonvolatile Memory and 3D Electronics Applications

NASA’s Jet Propulsion Laboratory has developed a nano-electro-mechanical resonator (NEMR) based on vertically aligned carbon nanofibers (CNFs) that is suitable for applications requiring high sensitivity, broad tenability, low loss (high Q), low power consumption, and small size. Other nanoscale resonators have been demonstrated using top-down fabrication approaches, but these generally involve complicated and expensive electron beam lithography. JPL’s bottom-up fabrication approach yields robust, vertically oriented CNFs that can be used to form high-Q, high-frequency NEMRs. In addition, the resonant frequency of these NEMRs can be tuned by selecting the length and diameter of the CNFs. This allows for a highly integrated, ultra-low-power, high-data-rate, and wide-bandwidth NEMR-based transceiver architecture.

A Nanotube Film Electrode and Electroactive Device Fabricated with the Nanotube Film Electrode and Methods for Making the Same

Applications include optical devices, electromechanical energy conversion, medical devices, sonar, and transducers.NASA’s Langley Research Center offers an all-organic electroactive device system fabricated with single-wall carbon nanotubes (SWCNT). The enhanced design offers higher electroactive performance in comparison with conventional electroactive device systems fabricated with metal electrodes or other conducting polymers. The new structure allows for significant improvement of the electroactive strain due to relief of the constraint on the electroactive layer. It exhibits superb actuation properties and can withstand high temperatures with improved mechanical integrity and chemical stability. In addition, the electroactive device can be made transparent, allowing for use in optical devices. NASA is seeking development partners and potential licensees.
