Next important step toward quantum computer with quantum dots

Scientists have have succeeded in linking two different quantum systems.

Graphene field-effect transistor is key to faster DNA sequencing

Graphene looks to hold the key to real-time, high throughput DNA sequencing, a technique that would revolutionise medical research and testing.

3D imaging of objects with details as small as 25 nanometers

Scientists have created 3D images of tiny objects showing details down to 25 nanometres. In addition to the shape, the scientists determined how particular chemical elements were distributed in their sample and whether these elements were in a chemical compound or in their pure state.

Split x-ray flash shows rapid processes

New method should make more precise experiments on x-ray lasers possible.

Fascinating quantum transport on a surface

Topological insulators are an exceptional group of materials. Their interior acts as an insulator, but the surface conducts electricity extremely well. Scientists now could measure this for the first time directly, with extremely high temporal resolution and at room temperature. In addition, they succeeded to influence the direction of the surface currents with a polarized laser beam.

Wrapping carbon nanotubes in polymers enhances their performance

Scientists developed a technique that 'exfoliates' aggregated clumps of CNTs and disperses them in solvents. It involves wrapping the tubes in a polymer using a bond that does not involve the sharing of electrons. The technique is called non-covalent polymer wrapping.

Solving molybdenum disulfide's 'thin' problem

Research team increases material's light emission by twelve times.
