The international team of scientist of Peter the Great St. Petersburg Polytechnic University (SPbPU), Leibniz University Hannover (Leibniz Universität Hannover) and the Ioffe Institute found a way to improve nanocomposite material which opens new opportunities to use it in hydrogen economy and other industries. The study is dedicated to the composite material, a semiconductor based on titanium dioxide. Its applications are widely studied by the researchers all over the world.
Researchers have developed a microscopic "trampoline" that can absorb microwave energy and bounce it into laser light -- a crucial step for sending quantum signals over long distances.
A team led by Associate Professor Yang Hyunsoo from the National University of Singapore Faculty of Engineering has found a practical way to observe and examine the quantum effects of electrons in topological insulators and heavy metals. This could later pave the way for the development of advanced quantum computing components and devices.
Australian scientists have achieved a new milestone in their approach to creating a quantum computer chip in silicon, demonstrating the ability to tune the control frequency of a qubit by engineering its atomic configuration. The work has been published in Science Advances.
Electrical circuits are constantly being scaled down and extended with specific functions. A new method now allows electrical contact to be established with simple molecules on a conventional silicon chip. The technique promises to bring advances in sensor technology and medicine, as reported in the journal Nature by chemists from the University of Basel and researchers from IBM Research-Zurich in Rüschlikon.
Star-shaped gold nanoparticles, coated with a semiconductor, can produce hydrogen from water over four times more efficiently than other methods - opening the door to improved storage of solar energy and other advances that could boost renewable energy use and combat climate change, according to Rutgers University-New Brunswick researchers.
Researchers have demonstrated nanomaterial-based white-light-emitting diodes (LEDs) that exhibit a record luminous efficiency of 105 lumens per watt.
Superconductor-ferromagnet structures are widely regarded as the building blocks of superconducting spintronic technology. More conventional spintronic devices typically require large currents, so researchers are investigating the viability of low-resistance superconductors. Their new results could answer longstanding questions about how SF structures interact. They reveal a general mechanism of the long-range electromagnetic proximity effect in SF structures in Applied Physics Letters.
Among researchers, graphene has been the hottest material for a decade. Now, two researchers from the University of Kansas have connected a graphene layer with two other atomic layers (molybdenum diselenide and tungsten disulfide) thereby extending the lifetime of excited electrons in graphene by several hundred times. The work may speed development of ultrathin and flexible solar cells with high efficiency.
Researchers from Sandia National Laboratories have developed a tiny silicon-based device that can harness what was previously called waste heat and turn it into DC power. Their advance was recently published in Physical Review Applied.
