Physicists discover a new switch for superconductivity

Under certain conditions—usually exceedingly cold ones—some materials shift their structure to unlock new, superconducting behavior. This structural shift is known as a "nematic transition," and physicists suspect that ...

A versatile hydrogel network-repairing strategy

Hydrogen bond engineering can convey stretchability, toughness and self-healing properties to materials, although enhancement effects of conventional hydrogen bonds is limiting due to their weak interaction strength. For ...
