'Oscar Madison' approach to solar cells may outshine 'Felix Unger' design

An international team of researchers has for the first time demonstrated that random, haphazardly grown silicon nanowires can significantly boost the power-producing capabilities of solar cells by trapping a broad spectrum of light waves and capturing sunlight streaming in from a wide variety of angles.

Ferroelectrics could pave way for ultra-low power computing

Engineers at the University of California, Berkeley, have shown that it is possible to reduce the minimum voltage necessary to store charge in a capacitor, an achievement that could reduce the power draw and heat generation of today's electronics.

European project achieves major milestone towards fabricating silicon photonics circuits in CMOS foundries

By demonstrating for the first time a 40Gbit/s optical modulator in silicon with a record extinction ratio of 10dB (the power difference between the 1 and 0 data levels), members of the HELIOS Project accomplished one of the key project goals needed to build and optimize the entire supply chain for fabricating complex functional silicon- photonics devices from design to the process level.

Ultrasmall peptides harnessed to repair spinal disc damage

New ultrasmall peptides that can be used as building blocks for a wide range of regenerative applications such as spinal disc replacement and cartilage repair have been developed by scientists at the Institute of Bioengineering and Nanotechnology (IBN), the world's first bioengineering and nanotechnology research institute. These peptides spontaneously assemble in water to form hydrogels, which resemble collagen, a major component of connective tissues found in cartilage, ligaments, tendons, bone and skin.
