2-D topological physics from shaking a 1-D wire

Limiting quantum particles to move in one, two, or three dimensions has led to the observation of many striking phenomena. A prime example is the quantization of the Hall conductance measured in 2-D materials in a strong ...

Inventing the world's strongest silver

A team of scientists has made the strongest silver ever—42 percent stronger than the previous world record. But that's not the important point.

Physicists find weak spots in ceramic/graphene composites

Physicists and materials scientists from Peter the Great St.Petersburg Polytechnic University (SPbPU) analyzed the structures in nanomaterials made of ceramic and graphene plates, in which cracks appear most frequently. The ...

Cable bacteria: Living electrical wires with record conductivity

A team of scientists from the University of Antwerp (Belgium), Delft University of Technology (Netherlands) and the University of Hasselt (Belgium) have reported on bacteria that power themselves using electricity and can ...

Theory reveals the nature of silicon carbide crystals defects

Imperfections of crystal structure, especially edge dislocations of an elongated nature, deeply modify basic properties of the entire material and, in consequence, drastically limit its applications. Using silicon carbide ...

A unique conducting state under UV-irradiation

A highly conducting state has been found in a molecular crystal under UV-irradiation. The state reversibly appears in accordance with UV-irradiation, but does not appear by any other method such as raising the temperature, ...

From crystals to glasses: a new unified theory for heat transport

Theoretical physicists from SISSA and the University of California at Davis have developed a new approach to heat transport in materials, which finally allows crystals, polycrystalline solids, alloys and glasses to be treated ...
