Magnetic 'T-Budbots' made from tea plants kill and clean biofilms (w/video)

Researchers have made magnetically propelled microbots derived from tea buds, which they call 'T-Budbots', that can dislodge biofilms, release an antibiotic to kill bacteria, and clean away the debris.

Nanoscale vortices with a unique property

For the first time, researchers have managed to create and identify antiferromagnetic skyrmions with a unique property: critical elements inside them are arranged in opposing directions. Scientists have succeeded in visualising this phenomenon using neutron scattering.

A multishot lensless camera in development could aid disease diagnosis

Researchers are developing a new type of imaging that does not require a lens and uses reconfigurable particle-based masks to take multiple shots of an object.

The world's smallest 'refrigerator' can only be seen through an electron microscope

Researchers have succeeded in creating thermoelectric coolers that are only 100 nanometers thick and have developed an innovative new technique for measuring their cooling performance.

New materials: A toggle switch for catalysis

Researchers showed that a special material made of lanthanum, strontium, iron and oxygen can be switched back and forth between two different states: In one state the material is catalytically extremely active, in the other less so. The reason for this is the behavior of iron nanoparticles on the surface.

Ambient vibration energy harvester with automatic resonance tuning mechanism

Energy harvesting technology with automatic resonance tuning mechanism. Possible application for an stand-alone power source for IoT or small electronics.

Scientists turn nanoparticle into Trojan horse to kill cancer cells without using drugs

Cancer cells are killed in lab experiments and tumour growth reduced in mice, using a new approach that turns a nanoparticle into a 'Trojan horse' that causes cancer cells to self-destruct.
