For the Kerker effect to occur, particles need to have electric and magnetic polarizabilities of the same strength. This, however, is very challenging to achieve, as magnetic optical resonances in small particles are relatively ...
We all know bubbles from soapy baths or sodas. These bubbles of everyday experience on Earth are up to a few inches across, and consist of a thin film of liquid enclosing a small volume of air or other gas. In space, however, ...

Using Atacama Large Millimeter/submillimeter Array (ALMA), researchers have conducted interferometric observations of the elliptical galaxy NGC 3557 to investigate molecular gas emission from this source. Results of these ...
Researchers in Eindhoven have developed a new type of low-energy, nanoscale laser that shines in all directions. The key to its omnidirectional light emission is the introduction of something that is usually highly undesirable ...

One-fifth of global electricity consumption is based on lighting; efficient and stable white-light emission with single materials is ideal for applications. Photon emission that covers the entire visible spectrum is, however, ...
NUS chemists have developed design guidelines for a type of material platform which can activate and adjust the light emission ability of organic molecules for lighting and display applications.
