It is not every day that scientists are able to produce an entirely new kind of light, but when they do the implications can be dramatic. When twisted light beams carrying orbital angular momentum ...

Thermoelectric materials convert heat to electricity and vice versa, and their atomic structures are closely related to how well they perform. Now researchers have discovered how to change the atomic ...

In a typical visible laser beam, there are potentially many millions of transverse modes per square millimetre 1, an extraordinary resource if it could be exploited. Yet for many years, only Gaussian ...

Light usually travels in straight lines, but what if it could twist, spiral, and behave like a miniature tornado? Scientists have now made this possible by creating optical tornadoes (also called ...

An international research team has develop for the first time light fields using caustics that do not change during propagation. With the new method, the physicists cleverly exploit light structures ...

An international team of scientists developed a nanoparticle structure which, when added to a solar cell, was shown to scatter light and potentially reflect it many times within the cell, contributing ...

We can frequently find in our daily lives a localized wave structure that maintains its shape upon propagation—picture a smoke ring flying in the air. Similar stable structures have been studied in ...

Subwavelength-scale nanorods were implemented on the hexagonal pyramid of photochemically etched light-emitting diodes (LEDs) to improve light extraction efficiency (LEE). Sequential processes of Ag ...

Photosynthesis, the natural process of converting sunlight energy into chemical energy and generating molecular oxygen, is a remarkable natural phenomenon that not only forms the basis for sustaining ...

Researchers showed how combining twisted light and frequency combs together can produce an even more novel structure of light. It is not every day that scientists are able to produce an entirely new ...
