Heat affects not only our well-being, but also the performance and lifespan of systems and devices. However, it is often difficult to measure these effects accurately. Go to Source Metal oxides are abundant in nature and central to technologies such as photocatalysis and photovoltaics. Yet, many suffer from poor electrical conduction, caused by strong repulsion between electrons in neighboring metal atoms. Go to Source Magic-angle twisted bilayer graphene (MATBG) is a material created by stacking two sheets of graphene onto each other, with a small twist angle of about 1.1°. At this “magic angle,” electrons move very slowly, which can lead to the emergence of highly correlated electron states. Go to Source Temperatures of more than 10,000°C and a hail of charged particles from the fusion fuel (plasma): These are extreme conditions that the exhaust wall (divertor) of future fusion power plants will need to withstand. It makes handling the exhaust stream one of the main challenges to realizing clean, safe and affordable commercial fusion power plants. […] Since the 1990s, evidence has been growing that quantum computers should be able to solve a range of particularly complex computational problems, with applications in everything from supply chain management to medicine and beyond. Go to Source A team from the Universitat Politècnica de València (UPV) and the University of Vigo (UVigo) has just published in Nature the results of a study in which they have uncovered why bridges—specifically steel truss bridges—do not collapse when affected by a catastrophic event such as an impact or an earthquake. And their conclusions are similar […] Seventy years ago, in Osmond Laboratory on Penn State’s University Park campus, Erwin W. Müller, Evan Pugh Research Professor of Physics, became the first person to “see” an atom. In doing so, Müller cemented his legacy, not only at Penn State, but also as a pioneer in the world of physics and beyond. Go to […] Imagine a clock that doesn’t have electricity, but its hands and gears spin on their own for all eternity. In a new study, physicists at the University of Colorado Boulder have used liquid crystals, the same materials that are in your phone display, to create such a clock—or, at least, as close as humans can […] Graphene is an extraordinary material—a sheet of interlocking carbon atoms just one atom thick that is stable and extremely conductive. This makes it useful in a range of areas, such as flexible electronic displays, highly precise sensors, powerful batteries, and efficient solar cells. Go to Source The existing bottleneck in efficiently miniaturizing components for quantum computers could be eased with the help of 3D printing. Go to Source It doesn’t take an expert photographer to know that the steadier the camera, the sharper the shot. But that conventional wisdom isn’t always true, according to new research led by Brown University engineers. Go to Source For over a hundred years, schoolchildren around the world have learned that ice melts when pressure and friction are applied. When you step out onto an icy pavement in winter, you can slip up because of the pressure exerted by your body weight through the sole of your (still warm) shoe. But it turns out […] Spintronics, or spin-electronics, is a revolutionary approach to information processing that utilizes the intrinsic angular momentum (spin) of electrons, rather than solely relying on electric charge flow. This technology promises faster, more energy-efficient data storage and logic devices. A central challenge in fully realizing spintronics has been the development of materials that can precisely control […] Researchers at The City College of New York have shown how a quantum emitter, the nitrogen-vacancy (NV) center in diamond, interacts in unexpected ways with a specially engineered photonic structure when moved around with a scanning tip. Go to Source A research team has developed a novel direct sampling method based on deep generative models. Their method enables efficient sampling of the Boltzmann distribution across a continuous temperature range. The findings have been published in Physical Review Letters. The team was led by Prof. Pan Ding, Associate Professor from the Departments of Physics and Chemistry, […] |
