Engineers use deep learning to reconstruct holograms and improve optical microscopy

Ability to produce more accurate images more quickly could aid diagnostic medicine.

Fine felted nanotubes - a new composite material made of carbon nanotubes

Carbon nanotubes (CNTs) either cannot be combined adequately with other materials, or if they can be combined, they then lose their beneficial properties. Scientists have now developed an alternative method, with which CNTs can be combined with other materials, so that they retain their characteristic properties.

Watching atoms move in hybrid perovskite crystals reveals clues to improving solar cells

A team of researchers has for the first time observed nanoscale changes deep inside hybrid perovskite crystals that could offer new insights into developing low-cost, high-efficiency solar cells.

A ferromagnetic material with promising properties

Researchers have developed a method for synthesising Europium (II) oxide nanoparticles - a ferromagnetic semiconductor that is relevant for data storage and data transport.

Designing new metal alloys using engineered nanostructures

Scientists take advantage of electron microscopes to see tiny nanostructures in fine detail and learn what happens when they are exposed to heat, radiation, and mechanical forces. One area they are interested in are nanostructured metal alloys (metals mixed with other elements) that incorporate nanometer-sized features into classical materials to enhance their performance.

Nano-watch has steady hands

An international team of researchers use tiny silicon nano-cylinders as the ultra-stable hands of a clock. Using a laser to levitate the tiny rod, they make the nano-hands tick with pulses of polarized light.

The microscopic origin of efficiency droop in LEDs

Semiconductor study shows that the coupling between electrons and thermal vibrations may be sapping energy from LEDs.

Researchers use CRISPR-Cas9 as a programmable nanoparticle for DNA nanomapping

Researchers have developed new nanomapping technology that could transform the way disease-causing genetic mutations are diagnosed and discovered.

Physicists explain metallic conductivity of thin carbon nanotube films

An international team of researchers has examined the optical and dielectric properties of thin macroscopic films based on single-walled carbon nanotubes and obtained an explanation for the metallic nature of their conductivity using infrared and terahertz spectroscopy.

Topological insulators: one glimpse is enough

Topological insulators are new materials with special electronic properties and are of great fundamental and applications-oriented interest. Nevertheless, physicists have wrestled with a ten-year-old puzzle in which the results from the two best methods to probe their electronic states disagree. Researchers now know exactly why.

Nanoparticles help with malaria diagnosis - new rapid test in development

A new research project is developing a new test method to detect malaria parasites in blood.
