'Smart material' chin strap harvests energy from chewing

It is hoped that the device can generate electricity from eating, chewing and talking, and power a number of small-scale implantable or wearable electronic devices, such as hearing aids, cochlear implants, electronic hearing protectors and communication devices.

For electronics beyond silicon, a new contender emerges

Using a quantum material called a correlated oxide, researchers have achieved a reversible change in electrical resistance of eight orders of magnitude, a result the researchers are calling 'colossal'. In short, they have engineered this material to perform comparably with the best silicon switches.

Advanced molecular 'sieves' could be used for carbon capture

Newly-developed synthetic membranes provide a greener and more energy-efficient method of separating gases, and can remove carbon dioxide and other greenhouse gases from the atmosphere, potentially reducing the cost of capturing carbon dioxide significantly.

The fate of the Efimov trimer under confinement

As well as providing new fundamental insights into this prototypical few-body problem, new research results have important implications for on-going atomic experiments aimed at detecting universality in the three-body system, and it opens new avenues towards the realisation of long-lived many-body states of trimers.

New study helps uncover mechanism behind solid-solid phase transitions

Two solids made of the same elements but with different geometric arrangements of the atoms, or crystal phases, can produce materials with different properties. Coal and diamond offer a spectacular example of this effect. Researchers have now found that some crystals have an easier time of making the solid-solid transition, if they take it in two steps.
