Tiny swimming donuts deliver the goods

Microscopic, 3D-printed, tori - donuts ­ - coated with nickel and platinum may bridge the gap between biological and synthetic swimmers, according to an international team of researchers.

Detailed insights into the structure of nanocapsules used for drug delivery

Scientists want to understand in as much detail as possible how the container molecules and the active substances arrange and what properties result from this.

Microrobots clean up radioactive waste (w/video)

Researchers have developed tiny, self-propelled robots that remove radioactive uranium from simulated wastewater.

A stretchable stopwatch lights up human skin

Researchers have developed a stretchable light-emitting device that operates at low voltages and is safe for human skin.

An electronic signal expands material by a factor of 100

Researchers have discovered a material that can both increase and reduce its volume when exposed to a weak electrical pulse. In a sponge, or filter, the researchers can control the size of particles that pass through.

Nanoelectronics simulations to identify optimal heat-evacuating properties

Team simulates nanoelectronics through data-centric lens, gaining a 140-fold speedup on the Summit supercomputer.

Researchers use light emitted from nanoparticles to intricately control biological processes

New nanoparticles can adjust the beating speed of heart cells by emitting different colours of light. Light from nanoparticle clusters was also able to activate anticancer drugs within cells.
