Tuning thermal expansion with origami metamaterials

Scientists have combined experiments and simulations to demonstrate that origami metamaterials provide a new platform for the design of systems with a wide range of coefficients of thermal expansion.

Nanogenerator-powered acceleration sensor

Researchers have demonstrated a self-powered acceleration sensor based on liquid metal triboelectric nanogenerator, which was composed of an inner liquid metal droplet (mercury) and an outer acrylic shell.

Killing cancer in the heat of the moment

A new method efficiently transfers genes into cells, then activates them with light. This could lead to gene therapies for cancers.
