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.
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.
For the first time using a water-based solution, researchers have created a long-lasting and more efficient nuclear battery that could be used for many applications such as a reliable energy source in automobiles and also in complicated applications such as space flight.
What holds white, black, and red phosphorus together - and prevents it from falling apart, for example into much-sought-after atomically thin networks and nanowires? This is what scientists now found out using numerical modeling.
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.
Researchers have devised a new simulation technique which reliably predicts the structure and behaviour of different materials, in order to accelerate the development of next-generation batteries for a wide range of applications.
Researchers have developed a new model to study the motion patterns of bacteria in real time and to determine how these motions relate to communication within a bacterial colony. They chemically attached colonies of E. coli bacteria to a microcantilever, coupling its motion to that of the bacteria.
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.
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.
