Nano & NIL Newsletter
- stay in front of development with NIL Technology
Welcome to yet another issue of the Nano & NIL newsletter presenting this year’s winner of the NILT Summer Competition Jeffrey Kettle, together with his girlfriend Rebecca Williams. We thank them both for an enjoyable afternoon in Copenhagen and the visit at our facilities.
In this week, we also bring you the news about micro batteries built with viruses and half the size of a human cell developed at MIT by professor Paula T. Hammond and colleagues. Batteries consist of two opposite electrodes, an anode and a cathode, separated by an electrolyte. The MIT team have created both the anode and the electrolyte. First an array of 4-8 µm diameter posts is formed on a rubbery material by soft-lithography. On top of the posts several layers of polymers are deposited which in the battery will act as the electrolyte. On top of the polymer layers the anode is formed by self-assembly of viruses containing cobalt oxide. Finally the layered structure is transferred to a surface by reverse printing. The electrode arrays exhibit full electrochemical functionality. Now the researchers are developing a technique to form the cathode by self-assembly to form a complete micro battery. Read this and the 7 other very interesting news below.
Editor, CTOThe 8 most important Nano & NIL News globally the past week Microbatteries Could Power Tomorrow's Miniature Devices
Forget 9-volts, AAs, AAAs or D batteries: The energy for tomorrow's miniature electronic devices could come from tiny microbatteries about half the size of a human cell and built with viruses.
Northeastern University Physicists Develop Nano-Optical Lens
Using semiconductor nanotechnology, Srinivas Sridhar, Ph.D., Distinguished Professor and Chair of Physics at Northeastern University, and his team of researchers from the university’s Electronic Materials Research Institute have created a new microlens that focuses infrared light at telecommunication frequencies.
IBM Makes First Steps Toward Carbon Nanotube-Based Nanophotonic Devices
Big Blue said its researchers achieved this development by combining a single nanotube-based field-effect-transistor with a pair of metallic nano-mirrors on a chip, and controlling optical emission properties from the nanotube, including emission wavelength and distribution of emitted light.

Scientists Discover New and Fast Method for Making Biological Chips
Scientists at The University of Manchester have developed a new and fast method for making biological ‘chips’ – technology that could lead to quick testing for serious diseases, fast detection of MRSA infections and rapid discovery of new drugs.
Polymer Electric Storage, Flexible and Adaptable
The proliferation of solar, wind and even tidal electric generation and the rapid emergence of hybrid electric automobiles demands flexible and reliable methods of high-capacity electrical storage. Now a team of Penn State materials scientists is developing ferroelectric polymer-based capacitors that can deliver power more rapidly and are much lighter than conventional batteries.
Beyond Jewelry - Nanotechnology Engineers New Uses for Gold
The glitter of gold may hold more than just beauty, or so says a team of MIT nanotechnology researchers that is working on ways to use tiny gold rods to fight cancer, deliver drugs and more.
