Electronic devices rely on materials whose electrical properties change with temperature, making them less stable in extreme conditions. A discovery that challenges conventional wisdom in physics ...

Many atomic nuclei have a magnetic field ... to measure another bismuth isotope with a different nuclear structure. Unfortunately, bismuth does not have a second stable isotope, so the research ...

One hypothesis is that the atomic structure of bismuth constrains electron movement in a way that mimics the behaviour of topological materials, recently discovered exotic substances whose ...

Ultrathin bismuthene islands on graphite slide freely in one direction and pause unpredictably, revealing new ways to control ...

Atomic and molecular interactions with photons ... This interaction is determined largely by the electronic structure of atoms and molecules; photon absorption or emission is associated with ...

Many atomic nuclei possess a magnetic field ... to analyze another bismuth isotope with a different nuclear structure. Since bismuth does not have a second stable isotope, thus the research ...

In solid materials, heat travels in two main ways—through moving electrons and through vibrations in the atomic structure ... The other is a mix of bismuth and antimony (Bi₀.

To boost performance, these materials must do two things at once: block the flow of heat through atomic vibrations in their structure, while allowing electrical ... commercially available compounds ...

Additionally, because of their differing chemical and mechanical characteristics, the two materials did not blend on the atomic scale. Instead the bismuth-antimony component selectively ...
