Ultra-fast extreme ultraviolet lasers open window into the nanoworld

Researchers have used ultra-fast extreme ultraviolet lasers to measure the properties of materials more than 100 times thinner than a human red blood cell.

New technology prolongs blood circulation for virtually any nanomedicine, boosting therapeutic efficiency

Scientists have developed a breakthrough technology to resolve a key problem that has prevented the introduction of novel drugs into clinical practice for decades.

Higher-order topology found in 2D crystal

The research team took a new approach by using the Josephson junctions to spatially resolve the supercurrent flow and to show that WTe2 does indeed appear to have hinge states and be a higher-order topological insulator.

The smallest micro-gripper, grown on optical fibers, is operated remotely with light

The 200-micrometer gripers are controlled remotely, without electric wiring or pneumatic tubing, with green light delivered through the fibers - absorbed light energy is directly converted into the gripper jaws' action.
