Scientists have observed a unique particle that moves easily one way, yet resists at 90 degrees. These semi-Dirac fermions were observed using their energy signature in a topological metal. Particles ...

Scientists in Japan have isolated an important type of electron for further study. Dirac electrons develop in certain conditions where cone-shaped openings appear in solid matter. A new paper ...

Researchers have detailed the physics behind a phenomenon that allows them to create spin in liquid droplets using ultrasound waves, which concentrates solid particles suspended in the liquid. The ...

However, due to its fragility, aerogel has played a vital role in space exploration. Aerogels are 99.8 per cent air. They are ...

Materials scientists are measuring the rolling friction of tiny, micrometer-sized particles. These measurements permit them to better understand everyday products such as concrete. For the first time, ...

Active matter: this microscope image shows part of a cluster of self-propelled particles, colour-coded according to their distance from the centre. (Courtesy: Jie Zhang, Ricard Alert, Jing Yan, Ned S ...

Particle analysis is key in solid-state battery development, influencing performance and safety through precise measurement of size, morphology, and density.
