Magnetic vortices come full circle

The first experimental observation of three-dimensional magnetic 'vortex rings' provides fundamental insight into intricate nanoscale structures inside bulk magnets, and offers fresh perspectives for magnetic devices.

Raman holography

Scientists report on a novel Raman holographic technique capable of tracking individual particles in 3D volumes from one single image.

How to store cipher data in magnetic skyrmions

Scientists propose direct magnetic writing of skyrmions, i.e. magnetic quasiparticles, and skyrmion lattices, within which it is possible to encode, transmit, process information, and produce topological patterns with a resolution of less than 100 nanometers.

How does the spider spin its self-assembled silk?

Researchers report on a new model for spider silk assembly. The key to spider silk 'spinning' is a combination of acidification and a process known as liquid-liquid phase separation, or LLPS.

Researchers run a 'speed test' to boost production of carbon nanotubes

Researchers have investigated the procedure for catalyst delivery used in the most common method of carbon nanotube production, chemical vapor deposition (CVD), offering what they call a simple and elegant way to boost productivity and pave the way for cheaper and more accessible nanotube-based technology.

A shapeshifting material based on inorganic matter

By embedding titanium-based nanosheets in water, scientists have created a material using inorganic materials that can be converted from a hard gel to soft matter using temperature changes.
