Researchers at the University of British Columbia have demonstrated an entirely new way to precisely control electrical currents by leveraging the interaction between an electron's spin and its orbital rotation around the nucleus.
UW researchers have created AuraRing, a ring and wristband combination that can detect the precise location of someone's index finger and continuously track hand movements.
Magnetic materials play important roles in electrical products. These materials are usually manufactured by means of established production techniques and use of rare earth metals. Several research teams at TU Graz are working on alternative, more environmentally friendly production methods.
Researchers at the National Institute of Standards and Technology (NIST) and their colleagues have for the first time created and imaged a novel pair of quantum dots -- tiny islands of confined electric charge that act like interacting artificial atoms. Such "coupled" quantum dots could serve as a robust quantum bit, or qubit, the fundamental unit of information for a quantum computer.
A team of scientists led by a physicist at the University of California, Riverside, has discovered an electrical detection method for terahertz electromagnetic waves, which are extremely difficult to detect. The discovery could help miniaturize the detection equipment on microchips and enhance sensitivity.
An MRI study investigating the influence of changes in the neuroanatomy of trigeminal neuralgia found that both trigeminal nerve and brain structures such as the hippocampus can predict the surgical treatment outcome. Greater trigeminal nerve and hippocampus volumes were more associated with non-responders patients.
Scientists have refined a technique called mass spectrometry imaging (MSI) that translates reams of data into detailed visuals of the molecular makeup of biological samples. Their work, published this week in Analytical Chemistry, features images with mass resolution so high that every color in the image represents a distinct kind of molecule.
Smaller is better when it comes to microchips, researchers said, and by using 3D components on a standardized 2D microchip manufacturing platform, developers can use up to 100 times less chip space. A team of engineers has boosted the performance of its previously developed 3D inductor technology by adding as much as three orders of magnitudes more induction to meet the performance demands of modern electronic devices.
An international group of scientists, including Skoltech Professor Sergey Rykovanov, has found a way to generate intense 'twisted' pulses. The vortices discovered by the scientists will help investigate new materials. The results of their study were published in the prestigious journal, Nature Communications.
An international team of Russian, Australian and Korean researchers have experimentally trapped an electromagnetic wave in a gallium arsenide nanoresonator for a record-breaking time, over 200 periods of one wave oscillation. The trap has also been tested as a basis for a light frequency nanoconverter. The results were published in Science. Researchers anticipate drastically new opportunities for subwavelength optics and nanophotonics, including the development of compact sensors, night vision devices, and optical data transmission technologies.
