Field emission of electrons is a crucial area of study in science and technology, with applications in signal processing and imaging at the atomic scale. Advances in electron microscopy techniques have made it possible to visualize matter on the native spatial and temporal scales of electron dynamics. Still, the analysis of attosecond electron pulses remains a major challenge.

The force necessary to induce slipping across an entire frictional interface may escalate over an extended period under a steady load as a result of various combinations of creep, structural, or chemical alterations of the interface.

Stargazers can expect the February full moon hours after their Lantern Festival dinner, as the moon will reach peak illumination at about 2:30 a.m. Beijing time on Monday, according to Kou Wen, senior engineer of Beijing Planetarium.
It will also be the smallest among all the 13 full moons in 2023, Kou told China Media Group.
