Materials that conduct electricity well, like metals, also tend to conduct heat. For instance, a metal spoon left in a hot cup of tea will get hot, while the ceramic mug remains cool. This is because good electrical conductors ...
While atoms are known to wiggle very fast, dopants added to a cuprate superconductor can also cause atoms to meander very slowly. An SLAC study shows this process, called atomic relaxation, offers a new way to explore quantum ...
Cooling systems are an integral part of many modern technologies, as heat tends to wear down materials and decrease performance in several ways. In many cases, however, cooling can be an inconvenient and energy-intensive ...
Radiative heat transfer is one of the most critical energy transfer mechanisms in nature. However, traditional blackbody radiation, due to its inherent characteristics, such as its non-directional, incoherent, broad-spectrum, ...
A ultrasound technique from the University of Nottingham will allow the production of sharper images inside live cells without causing damage at resolutions that were previously unattainable.
Researchers have developed a highly sensitive detector for identifying molecules via their infrared vibrational "fingerprint." This innovative detector converts incident infrared light into ultra-confined "nanolight" in the ...
Metamaterials are artificial materials that do not occur in nature. Their components function like atoms in conventional materials but have special optical, electrical and magnetic properties. Interaction between the components ...
For a wide variety of emerging quantum technologies, such as secure quantum communications and quantum computing, quantum entanglement is a prerequisite. Scientists at the Max-Planck-Institute for the Science of Light (MPL) ...
Chirality is a property of some molecules, subatomic particles, living organisms and other physical or biological systems. This property entails a lack of mirror symmetry in these systems' underlying structures.
Superconductivity is the phenomenon by which, at sufficiently low temperatures, electric current can flow in a metal with no resistance. While certain metals are excellent superconductors, other metals cannot superconduct ...
