Silicon nanowires: The Next Big Thing™ in chip design

CPTF 2012 The next step in transistor architecture will likely be silicon nanowires – extremely thin silicon wires that will form the transistor's chanel, surrounded on all sides by a wrap-around silicon oxide, high-K metal gate. "It's the ultimate fully-depleted device," the director of IBM's Semiconductor Research & Development Center …

Nanocapacitor slab to boost car batteries

Australian company CAP-XX has announced a supercapacitor module for cars that it hopes will take a load off chemical batteries. Capacitors are common in most electronic devices, thanks to their ability to hold a small charge for a short time. CAP-XX's current schtick is making very small and thin capacitors which, thanks to …

Boffins boost fuel-cell future with 'nanowire forest'

Researchers at a California university have developed a nanowire-based method to efficiently harvest hydrogen for fuel cells without the need for electricity, which is commonly generated by greenhouse-gas producing fossil fuels or nuclear reactors with their problematic waste. "This is a clean way to generate clean fuel," said …

Tubular cells: Georgia Tech demos nano-scale solar fab

The idea that got Solyndra into so much trouble – that a tube-shaped solar cell could be more efficient than a traditional flat design – didn’t disappear when its highest-profile manufacturer collapsed. It remains a strong focus of research efforts. There’s a good reason for this: if such designs can be fabricated at a …

Neat nanoparticles could bring 10TB disks

One of the Australian researchers behind a 2009 Nature paper outlining how optical media could reach 1.6 terabytes says Samsung has decided not to commercialise the technology, but has also published a new paper outlining how 12cm shinies could hit ten terabytes. Dr James Chon, Senior Lecturer at the Swinburne University of …

Lumpy nanoparticles improve thin film solar cells

A team at Swinburne University in Melbourne is claiming a breakthrough in the efficiency of nanoplasmonic solar cells. While it’s already feasible to cover the entire glass area of a building with invisible plastic solar cells, they’re nowhere near as efficient as traditional cell types: the very thin silicon layer they use …

SPRAY-ON antennas waved about at Google's techfest

Presenting at the new Google-backed talk fest "Solve for X", ChamTech Operations showed its nano tech-based antenna in a spray can, turning trees into antennas and connecting submarines by radio. The technology is easy to explain, but rather harder to realise. It comes in a aerosol with which one sprays nano-capacitors – onto …

Boffins build electric car from a single molecule

Dutch scientists have reported building a car that's a single molecule wide and is powered by electrons. The car is built out of a single molecule for the body, with four paddle-shaped “wheels” at the corners. Then electrons were applied by moving the tip of a scanning tunneling microscope close to the device, causing the …

Stanford boffins create skinnier ‘skin’

A group of scientists from Stanford University has created an artificial “skin” that acts as a stretchable, super-thin pressure sensor. The Bao Research Group led by Zhenan Bao has demonstrated the film, which is made from single-wall carbon nanotubes bent to act as springs. The real breakthrough, however, isn’t just creating …

Nanotubes, sulfur expand battery storage

The group that last year gave the world the unexplodable lithium battery is back, this time using a combination of nanotubes, sulfur and an electrolyte additive to achieve what they say is a tenfold improvement in capacity. In particular, the group, led by Stanford University’s Yi Cui, believes the sulfur-coated carbon …

Single-molecule 'motor' measures just a nanometer

It’s not the first single-molecule nano-motor, but it’s the first one to be driven by electricity: a Tufts research team has demonstrated that you can “provide electricity to a single molecule and get it to do something that’s not just random” (as team leader Charles Sykes put it). Previous single-molecule nano-motors have …

Aussie nano tech project gets AU$15m in global VC funding

A Queensland-based nanotech start-up has secured AU$15m in funding from a group of international biotechnology investors. Venture capital firm One Venture is backing the creation of start-up vehicle Vaxxas, which will allow the University of Queensland’s Australian Institute for Bioengineering and Nanotechnology (AIBN) …

Boffins demo one-molecule DNA 'walker' nano-bot

American boffins say that they have created tiny robot spiders or "walkers", each one of which is a single complicated molecule fashioned out of DNA. They have managed to get the molecular nanorobospiders to follow a trail of DNA "breadcrumbs". DNA walker nanobot in action. Credit: Paul Michelotti The sticking-up bits are …

Boffins test cancer-stinging 'nano-bee' swarms in mice

American medi-boffins say they have developed a way of using tiny nanotech devices, which they call "nanobees", to carry a potentially poisonous drug safely into the body for the purposes of killing cancerous tumours. The "bees" are so-called - as opposed to being named "nanowasps" or "nanocobras" or whatever - because the the …

Spy chief to Obama: Let DARPA fix economy

Newly-inaugurated President Barack Obama has been urged by a top US spysat chief to revitalise America's economy through the use of DARPA*, the legendary Pentagon barmy-boffinry bureau which has given the world the internet and the stealth bomber. More recently the agency has also sponsored initiatives such as mindreading peril- …

Chinese boffins show off unbelievably tight ring

Chinese nanojewellery experts have managed to fashion an exceptionally tiny ring out of just 36 atoms of gold. Incredibly minuscule as the golden nano-ring is, however, it is in fact the world's largest of its type. Brainboxes Shu-Yan Yu, Yi-Zhi Li, and Vivian Wing-Wah Yam - working at universities in Beijing, Nanjing and Hong …
