Light resonators used to move nano-sized objects
22:55 November 19, 2009 PST
Scientists at Cornell University report they can now use a light beam carrying a single milliwatt of power to move objects and even change the optical properties of silicon from opaque to transparent at the nanometric scale. Such an advancement could prove very useful for the future of micro-electromechanical (MEMS) and micro-optomechanical (MOMS) systems. Read More
Researchers push miniaturization even further with finFET transistors
19:29 November 17, 2009 PST
Researchers at Purdue University have reported important progress in developing finFETs, a type of transistor that some say will eventually substitute the silicon-based kind because it allows engineers to push miniaturization even further in the perpetual effort to validate the predictions of Moore's Law.

Producing carbon nanotubes on an industrial scale
By Darren Quick
23:54 November 3, 2009 PST
Carbon nanotubes promise to revolutionize everything from medicine to electronics and power generation. Unfortunately nanotubes are notoriously hard to work with and chemists worldwide have struggled for years to even make them. Now researchers have unveiled a method for the industrial-scale processing of pure carbon nanotube fibers that builds upon the tried-and-true processes that chemical firms have used for decades to produce plastics.

Replicating nano structure of butterfly wings could lead to better solar cells

Researchers have developed a technique to replicate biological structures, such as butterfly wings, on a nano scale. They focused on the tiny nano-sized photonic structures that are found in the insects’ cuticle, and which give insects their iridescence - that slightly metallic sheen that also seems to shift in color depending on the viewing angle. By replicating the biotemplate of butterfly wings, the researchers hope to be able to make various optically-active structures, such as optical diffusers or coverings that maximize solar cell absorption.

Take your iPod nano videos to a wider audience with the VideoBuddy AV out adapter

Owners of the new iPod nano 5G will no doubt be racking up hours of video footage by now and looking to inflict - I mean, share - their videos with all and sundry. While the nano’s 2.2-inch display might be ok “on the set”, nothing beats a TV to demand everyone’s attention. If you don’t have Apple TV, or don’t want to waste time turning on your computer to go through iTunes lest your audience disappear, GEAR4 have the perfect solution in the form of the VideoBuddy – a compact Audio Video (AV) kit that connects to the iPod nano dock connector and links to a TV via an RCA cable.

Carbon nanotubes used to build a near-ideal efficiency solar cell
04:34 September 14, 2009 PDT
Today's photovoltaic technology, while certainly promising, offers very poor efficiency because of inherent issues in its working mechanism. Using carbon nanotubes, however, Cornell University researchers now hope to lead the way to the next generation of highly efficient solar panels. Read More
Apple's iPod nano 5G gets a camera
By Darren Quick
22:29 September 9, 2009 PDT
Apple added a number of updates to various iPod models at its Rock and Roll event. The iPod that sported the most obvious changes was undoubtedly the nano, which now includes a built-in video camera, a much anticipated FM radio, and built-in pedometer. The new 5G nano also features a slightly (0.2-inches) larger 2.2-inch display, and built-in microphone and speaker, which means watching those newly recorded videos need not be a solitary affair.

Sound could be the key in building tomorrow's nanostructures
19:55 September 1, 2009 PDT
Researchers from Penn State University have found a way to precisely manipulate tiny objects using sound rather than optical instruments with a quick, energy-effective and technologically-simple technique that could have important applications in the fields of nanotechnology and biological research.

Nanoscale lasers continue to shrink, heralding new era in optical science
By Darren Quick
20:28 August 31, 2009 PDT
Breakthroughs are coming thick and fast – or should that be thin and fast – in the field of nanoscale lasers. It wasn’t even a month ago that we reported on the development of a laser emitting 'metal-semiconductor-metal sandwich', made up of a semiconductor as thin as 80 nanometers laying between 20-nanometer dielectric layers. But now researchers at the University of California, Berkeley, have reached a new milestone in laser physics by creating the world's smallest semiconductor laser, capable of generating visible light in a space smaller than a single protein molecule.

Not long ago we brought you an article about a tiny ‘nano air vehicle’ (NAV) that hovers by flapping its wings. Its creator, AeroVironment, has now released a video capturing details of the craft's impressive non-restricted flying capabilities. Read More
