In a new report published in Science, Yi-Lun Hong and a group of research scientists in materials science, engineering, and advanced technology in China and the U.K. investigated two-dimensional (2-D) materials to discover ...
Phys.org / Enhanced liquid repellence through flexible microstructures
Artificial surfaces that can repel liquids have attracted significant attention across scientific and industrial platforms to create functional topological features. But the role of the underlying structures that are in contact ...
Phys.org / Time-reversal of an unknown quantum state
Physicists have long sought to understand the irreversibility of the surrounding world and have credited its emergence to the time-symmetric, fundamental laws of physics. According to quantum mechanics, the final irreversibility ...
Phys.org / Controlling ice formation on gradient wettability surfaces for high-performance bioinspired materials
Ice-templating is a powerful technique to construct biological materials using ice nucleation and growth to obtain frozen material architectures, but scientists have been unable to control these two factors with effective ...
Phys.org / Breaking the absorption limit of silicon toward the short-wavelength infrared wavelength range via strain engineering
Silicon is widely used in the microelectronics industry although its photonics applications are restricted to the visible and partial near-infrared spectral range due to its fundamental optical bandgap. Researchers have therefore ...
