Researchers demonstrate how graphene can be used to build a detector of long wavelength (far infrared or terahertz) light that is as sensitive as any existing detector, but far smaller and more than a million times faster.
A computer and data scientist has won a $250,000 National Science Foundation grant to develop a scalable data-mining framework that will help manufacturers quickly discover desired materials for building their products.
In an unprecedented view inside a working lithium-ion battery, researchers used a neutron beam to 'see' lithium flow as the battery charged and discharged. The study could one day help explain why rechargeable batteries lose capacity over time, and sometimes even catch fire.
Optical circuits use light instead of electricity, making them faster and more energy-efficient than electrical systems. Scientists have developed a first building-block for photonic 'transistors' that requires record-low energy to operate. The device is a big step forward in the development and implementation of optical circuits.
Scientists have developed a new screening method that makes it possible to study cell membrane proteins that bind drugs, such as cannabis and adrenaline, while reducing the consumption of precious samples by a billion times.
Researchers analyzed the properties of elemental bonds between semiconducting phosphorus atoms in 2-D sheets. Two-dimensional phosphorus is not theoretical; it was recently created through exfoliation from black phosphorus.
On the nanoscale, adding fluorine to graphene had been reported to vastly increase the friction experienced when sliding against the material. Through a combination of physical experiments and atomistic simulations, researchers have discovered the mechanism behind this surprising finding, which could help researchers better design and control the surface properties of new materials.
Using an 'electric prism', scientists have found a new way of separating water molecules that differ only in their nuclear spin states and, under normal conditions, do not part ways. Since water is such a fundamental molecule in the universe, the recent study may impact a multitude of research areas ranging from biology to astrophysics.
Researchers developed a new method to selectively dope graphene molecules with nitrogen atoms. By seamlessly stringing together doped and undoped graphene pieces, they were able to form heterojunctions in the nanoribbons, thereby fulfilling a basic requirement for electronic current to flow in only one direction when voltage is applied - the first step towards a graphene transistor.
Over 100 years since the Nobel Prize-winning father and son team Sir William and Sir Lawrence Bragg pioneered the use of X-rays to determine crystal structure, researchers have made significant new advances in the field.
