Stretchable variable color nanosheet changes color with expansion and contraction

Variable color sheets with a film thickness of 400 nanometers are expected to be applied to adhesive-type display elements, as they can adhere to skin or be transferred to various electronic devices at room temperature utilizing the high adhesiveness of elastomers.

Joined nano-triangles pave the way to magnetic carbon materials

Graphene triangles with an edge length of only a few atoms behave like peculiar quantum magnets. When two of these nano-triangles are joined, a 'quantum entanglement' of their magnetic moments takes place: the structure becomes antiferromagnetic.

Researchers build sensor consisting of only 11 atoms

The sensor is capable of capturing magnetic waves and consists of an antenna, a readout capability, a reset button and a memory unit.

A remote control for neurons

Scientists synthesized three-dimensional fuzzy graphene on a nanowire template to create a superior material for photothermally stimulating cells.

Carbon nanotube transistors make the leap from lab to factory floor

Technique paves the way for more energy efficient, 3D microprocessors.

Carbon nanotubes can make home refrigeration more accessible for low-income households

Researchers replaced widely-used, but environmentally unfriendly, R134a refrigerant with the more energy-efficient R600a. They dosed R600a with multi-walled carbon nanotubes.

New stretchable, self-healing and illuminating electronic material for wearables and soft robots

Imagine a flexible digital screen that heals itself when it cracks, or a light-emitting robot that locates survivors in dark, dangerous environments or carries out farming and space exploration tasks. A novel material could turn these ideas into reality.
