Shapeshifting microrobots can brush and floss teeth

Posted: 05 Jul 2022 04:41 PM PDT

A robotic microswarm may one day automate the routine of rinsing, brushing, and flossing teeth. A multidisciplinary team developed the technology, which employs a magnetic field to direct the iron oxide nanoparticle-based microrobots into antimicrobial bristle- and floss-shaped arrays.

Researchers expand understanding of vortex spread in superfluids

Posted: 05 Jul 2022 04:41 PM PDT

Researchers have created a model that describes the spread and speed of tornado-like vortex tubes in superfluids. This work expands on a previous study that reported experimental results obtained in superfluid helium-4 within a narrow temperature range.

New photocatalytic membrane that can be cleaned using light energy

Posted: 05 Jul 2022 01:22 PM PDT

Researchers have developed a nanosheet-laminated photocatalytic membrane that demonstrates both excellent water permeance and photocatalytic activity. The membrane's photocatalytic properties make it easier to clean as irradiating the membrane with light successfully reduces fouling. This revolutionary membrane technology can be applied to water purification, and thus has the potential to contribute towards tackling both global environmental and energy issues by helping to ensure a supply of safe drinking water and clean energy.
