Understanding high efficiency of deep ultraviolet LEDs

Deep ultraviolet light-emitting diodes (DUV-LEDs) made from aluminium gallium nitride (AlGaN) efficiently transfer electrical energy to optical energy due to the growth of one of its bottom layers in a step-like fashion. ...

Gold nano-stars for intracellular delivery

Researchers from the Russian Academy of Sciences developed a new method for star-shaped nanoparticles synthesis based on laser irradiation. A wide range of customizable conditions provides an opportunity to create a comfortable ...

Superior noise control using graphene

Noise is a dangerous worldwide environmental pollutant: at normal levels found in cities it can induce annoyance, stress and fluctuations in sleep patterns which in turn increase the risk of type-2 diabetes, arterial hypertension, ...

Transformation through light

Laser physicists have taken snapshots of how C60 carbon molecules react to extremely short pulses of intense infrared light.

Precious metal tracks nanoplastics

Tiny plastic particles measuring about 100 nanometres (millionths of a millimetre) are used in many products, for example, to encapsulate dye or aromatic substances or as additives to shampoos and cosmetics. Many of them ...

Supercomputing helps study two-dimensional materials

Materials scientists study and understand the physics of interacting atoms in solids to find ways to improve materials we use in every aspect of daily life. The frontier of this research lies not in trial and error, though; ...

Wrinkles take the heat

Single atomic sheets of black phosphorus are attracting attention for their potential in future electronics applications. A*STAR researchers have now completed experiments at the nanoscale to unlock the secret of this material's ...

Nanoparticles may promote cancer metastasis

Nanoparticles can be found in processed food (e.g. food additives), consumer products (e.g. sunscreen) and even in medicine. While these tiny particles could have large untapped potential and novel new applications, they ...
