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.
New research could lead to light detectors that can see below the surface of bodies, walls, and other objects, with applications in emerging terahertz fields such as mobile communications, medical imaging, chemical sensing, night vision, and security.
A new route to making graphene has been discovered that could make it easier to ramp up to industrial scale. Graphene, which has super strength and the ability to conduct heat and electricity better than any other known material, has potential industrial uses that include flexible electronic displays, high-speed computing, stronger wind-turbine blades, and more-efficient solar cells, among other uses now under development.
Scientists have engineered and studied 'active vesicles'. These purely synthetic, molecularly thin sacs are capable of transforming energy, injected at the microscopic level, into organized, self-sustained motion.
