Physicists create five-lane superhighway for electrons

MIT physicists and colleagues have created a five-lane superhighway for electrons that could allow ultra-efficient electronics and more. The work, reported in the May 9 issue of Science, is one of several important discoveries by the same team over the last year involving a material that is essentially a unique form of pencil lead.

Manufacturing optimized designs for high explosives

When materials are subjected to extreme environments, they face the risk of mixing together. This mixing may result in hydrodynamic instabilities, yielding undesirable side effects. Such instabilities present a grand challenge across multiple disciplines, especially in astrophysics, combustion and shaped charges—a device used to focus the energy of a detonating explosive, thereby creating a high […]

New work extends the thermodynamic theory of computation

Every computing system, biological or synthetic, from cells to brains to laptops, has a cost. This isn’t the price, which is easy to discern, but an energy cost connected to the work required to run a program and the heat dissipated in the process.

Exceptionally large transverse thermoelectric effect produced by combining thermoelectric and magnetic materials

A NIMS research team has demonstrated for the first time ever that a simple stack of thermoelectric and magnetic material layers can exhibit a substantially larger transverse thermoelectric effect—energy conversion between electric and heat currents that flow orthogonally to each other within it—than existing magnetic materials capable of exhibiting the anomalous Nernst effect. This mechanism […]

Single pixel imaging enabled by fiber laser arrays is expected to achieve remote detection

Single-pixel imaging (SPI) is a novel computational imaging technique that has been widely studied in recent years. This technique only uses a single pixel detector without spatial resolution to obtain the spatial information of the target.

Possible new process for the synthesis of rare nuclei in the universe

A new nucleosynthesis process denoted as the νr-process has been suggested by scientists from GSI Helmholtzzentrum für Schwerionenforschung, Technische Universität Darmstadt, and the Max Planck Institute for Astrophysics. It operates when neutron-rich material is exposed to a high flux of neutrinos.
