Release describes application of machine learning form of artificial intelligence to predict the behavior of fusion plasma.

Physicists have demonstrated a new way to obtain the essential details of an isolated quantum system through direct observation. The method gives information about the likelihood of finding atoms at specific locations in the system with unprecedented spatial resolution far better than an optical microscope can provide. With this technique, scientists can obtain details on a scale of tens of nanometers -- smaller than the width of a virus.

E-waste recycling is far below what it should be to reduce its impact on the environment and human health simply because it is not economically feasible. Researchers from Japan are working on a way to change that using pulsed power technology.

Professor Li Jia and Gao Yuanhong from the Shenzhen Institutes of Advanced Technology (SIAT) of the Chinese Academy of Sciences and their collaborators developed a novel hybrid-layered architecture to improve the overall photodetection performance of organic phototransistors by simultaneously taking advantages of the charge-trapping effect and efficient carrier transport.

Tweaking the design of microring sensors enhances their sensitivity without adding more implementation complexity.

Collisions of lead nuclei take place under extreme physical conditions. Their course can be described using a model which assumes that the transforming, extremely hot matter -- the quark-gluon plasma -- flows in the form of hundreds of streaks. Until now, the 'fire streaks' seemed to be purely theoretical structures. However, the latest analysis of collisions of individual protons reinforces the hypothesis that they represent a real physical phenomenon.

Weyl semimetals are a recently discovered class of materials, in which charge carriers behave the way electrons and positrons do in particle accelerators. Researchers from the Moscow Institute of Physics and Technology and Ioffe Institute in St. Petersburg have shown that these materials represent perfect gain media for lasers.

Researchers at PSI have investigated a novel crystalline material that exhibits electronic properties that have never been seen before. It is a crystal of aluminum and platinum atoms arranged in a special way. This resulted in novel properties of electronic behaviour for the crystal as a whole, including so-called Rarita-Schwinger fermions in its interior.

Researchers from Tokyo University of Agriculture & Technology (TUAT), ORC Manufacturing Co. Ltd. and Techno Research., Ltd achieved high quality crystallization of amorphous silicon film by developing rapid heating technology with the microwave induced wireless heating lamp. The wireless lamp is excellent in energy saving, durability and maintainability, and it can be expected to be developed into a new heating device that is unprecedented.
