Out-sniffing bomb-sniffing dogs

Tel Aviv University researcher leads development of swift, small, highly reliable sensor to detect explosives

16-Nov-2010

Dogs have long been called man's best bomb detector –– until now. A Tel Aviv University scientist leads a research team that has developed a powerful electronic sensor to detect multiple kinds of explosives –– including those used in the recent Yemeni bomb threat. Based on nanotechnology ...

Measuring the electrical properties of nano-crystals

UK scientists help to create standards for measuring electric materials on the nanoscale

22-Oct-2010

The UK's National Physical Laboratory (NPL) is working to provide more reliable measurement of the electrical properties of materials used in nanotechnology – which could lead to much more accurate devices in the future. Scanning probe microscopy (SPM) won the Nobel Prize in 1986. It uses a ...

Sniffing out shoe bombs: A new and simple sensor for explosive chemicals

22-Oct-2010

University of Illinois chemists have developed a simple sensor to detect an explosive used in shoe bombs. It could lead to inexpensive, easy-to-use devices for luggage and passenger screening at airports and elsewhere. Triacetone triperoxide (TATP) is a high-powered explosive that in recent ...

Researchers show how cells open 'doors' to release neurotransmitters

18-Oct-2010

Like opening a door to exit a room, cells in the body open up their outer membranes to release such chemicals as neurotransmitters and other hormones. Cornell researchers have shed new light on this lightning-quick, impossibly small-scale process, called exocytosis, by casting sharp focus on ...

Radio chip and sensor in one

15-Oct-2010

RFID technology is on the advance. But, up to now radio chips primarily supply data for the identification of products. Researchers have now developed a transponder which measures temperature, pressure and humidity. The chip with sensor function could revolutionize the applications ...

Nano antenna concentrates light

Intensity increases 1,000-fold in Rice lab's experiment

23-Sep-2010

Everybody who's ever used a TV, radio or cell phone knows what an antenna does: It captures the aerial signals that make those devices practical. A lab at Rice University has built an antenna that captures light in the same way, at a small scale that has big potential. Condensed matter physicist ...

Good Vibrations: New atom-scale products on horizon

Breakthrough discovery enables nanoscale manipulation of the piezoelectric effect

25-Aug-2010

The generation of an electric field by the compression and expansion of solid materials is known as the piezoelectric effect, and it has a wide range of applications ranging from everyday items such as watches, motion sensors and precise positioning systems. Researchers at McGill University’s ...

Kinked nanopores slow DNA passage for easier sequencing

Sandia self-assembly and atomic-layer deposition improve process fivefold

04-Aug-2010

In an innovation critical to improved DNA sequencing, a markedly slower transmission of DNA through nanopores has been achieved by a team led by Sandia National Laboratories researchers. Solid-state nanopores sculpted from silicon dioxide are generally straight, tiny tunnels more than a thousand ...
