Digital lab-on-a-chip designs

Generally, a lab-on-a-chip (LOC) can run no more than a test or two. That's because the chips are designed manually. If the LOC were made using computer-aided design, you could run dozens of tests with a single drop of blood.

Groundbreaking new memory technology, which combines flash with phase change memory

Theseus was a great hero in Greek mythology known for qualities such as strength, courage and wisdom. Therefore it's no surprise that a team of Greek IBM scientists in Zurich and a professor from the University of Patras, Greece, borrowed his name as a codeword for a groundbreaking new memory technology, which combines flash with phase change memory (PCM) on a PCI-e card. Initial tests have clocked 12x and 275x improvements - and that's no myth.

Scientists find x-rays can cause reversible resistance changes

Synchrotron X-rays are frequently used to image a wide range of different materials, but they can also cause chemical changes as well. In a new study, researchers looked at how a material?s electrical resistance changes when it is irradiated with these high-energy X-rays.

Catalysis with gold-tipped CdSe nanorod clusters

The Au-tipped CdSe nanorods were found to significantly increase the efficiency for charge separation and collection of energetic electrons in the Au nanoparticles, leading to an exceptional improvement in photocatalyzing multiple-electron reduction (MER) reactions, even in aerobic aqueous solutions at room temperature.

This FIB doesn't lie: New microscope sees what others can't

In an effort to extract a little more truth from the world of nanomaterials and nanostructures, researchers at the National Institute of Standards and Technology have built the first low-energy focused ion beam (FIB) microscope that uses a lithium ion source.

Carbon nanotube-infused clothing may protect against chemical weapons

Nerve agents are among the world's most feared chemical weapons, but scientists at the National Institute of Standards and Technology have demonstrated a way to engineer carbon nanotubes to dismantle the molecules of a major class of these chemicals. In principle, they say, the nanotubes could be woven into clothing that destroys the nerve agents on contact before they reach the skin.

Organic crystal demonstrates superelasticity

Not only rubber is elastic: There is also another, completely different form of elasticity known as superelasticity. This phenomenon results from a change in crystal structure and was previously only found in alloys and certain inorganic materials. A Japanese scientist has now introduced the first superelastic organic compound.

Students build carbon nanostructures in hypergravity

A Spin Your Thesis! experiment has shown that carbon nano materials are built differently under conditions of hypergravity. These results are useful for understanding the synthesis of carbon nano structures and the behaviour of gliding arc discharges.

Spotting phase changes triggered by impurities

'What a curious feeling', says Alice in Lewis Carroll's tale, as she shrinks to a fraction of her size, and everything around her suddenly looks totally unfamiliar. Scientists too have to get used to these curious feelings when they examine matter on tiny scales and at low temperatures: all the behavior we are used to seeing around us is turned on its head.
