The characteristics of a new, iron-containing type of material that is thought to have future applications in nanotechnology and spintronics have been determined at Purdue University.

The native material, a topological insulator, is an unusual type of three-dimensional (3D) system that has the interesting property of not significantly changing its crystal structure when it changes electronic phases—unlike water, for example, which goes from ice to liquid to steam. More important, the material has an electrically conductive surface but a non-conducting (insulating) core.

However, once iron is introduced into the native material, during a process called doping, certain structural rearrangements and magnetic properties appear which have been found with high-performance computational methods.

A spot of sunshine is all it could take to get your washing done, thanks to pioneering nano research into self-cleaning textiles.

Researchers at RMIT University in Melbourne, Australia, have developed a cheap and efficient new way to grow special nanostructures—which can degrade organic matter when exposed to light—directly onto textiles.

The work paves the way towards nano-enhanced textiles that can spontaneously clean themselves of stains and grime simply by being put under a light bulb or worn out in the sun.

A British engineer has found a way to filter unwanted cells from blood using magnets — and his tool could be used in clinical trials as soon as next year.

Thanks to existing research, biochemical scientist George Frodsham knew it was possible to force magnetic nanoparticles to bind to specific cells in the body. But while other researchers did so primarily to make those cells show up in images, he wondered whether the same technique might allow doctors to remove unwanted cells from the blood.

“When someone has a tumour you cut it out,” he told The Telegraph. “Blood cancer is a tumour in the blood, so why not just take it out in the same way?”

Deadly conditions like leukaemia, sepsis and malaria could be drawn from the body using magnets, after a British engineer designed a blood filtering system which sieves away disease.

Dr George Frodsham, came up with the idea while studying how magnetic nanoparticles can be made to bind to cells in the body, to allow, for example those cells to show up on scanners.

But he realised that if it was possible to magnetise cells for imaging, it should also be possible to then suck them out of the blood.

AMOLF researchers and their collaborators from the Advanced Science Research Center (ASRC/CUNY) in New York have created a nanostructured surface capable of performing on-the-fly mathematical operations on an input image. This discovery could boost the speed of existing imaging processing techniques and lower energy usage. The work enables ultrafast object detection and augmented reality applications. The researchers publish their results today in the journal Nano Letters.

Image processing is at the core of several rapidly growing technologies, such as augmented reality, autonomous driving and more general object recognition. But how does a computer find and recognize an object? The initial step is to understand where its boundaries are, hence edge detection in an image becomes the starting point for image recognition. Edge detection is typically performed digitally using integrated electronic circuits implying fundamental speed limitations and high energy consumption, or in an analog fashion which requires bulky optics.

Superhydrophobic materials, which are excellent at repelling water, can be extremely useful for a whole range of reasons, both obvious and not-so-obvious. They can prevent ice from building up on surfaces, make electronics waterproof, make ships more efficient or keep people from peeing in public. Now engineers have found a quirky new use for superhydrophobic materials – making “unsinkable” metals that stay floating even when punctured.

Superhydrophobic materials get their water-repelling properties by trapping air in complex surfaces. These air bubbles make it hard for water to stick, so droplets instead bounce or roll right off. But, of course, air also makes things buoyant, so the team set out to test how superhydrophobic materials could be used to make objects that float better.

Circa 2009

March 19, 2009 Researchers at the University of Miami and at the Universities of Tokyo and Tohoku, Japan, have been able to prove the existence of a “spin battery,” that could have significant applications including much faster, less expensive and use less energy consuming computer hard drives with no moving parts, and could even be developed to power cars.

A “spin battery” is “charged” by applying a large magnetic field to nano-magnets in a device called a magnetic tunnel junction (MTJ). Like a toy car, the spin battery is “wound up” by applying a large magnetic field — no chemistry involved.
