The quantum sniffer dog

As humans, we sniff out different scents and aromas using chemical receptors in our noses. In technological gas detection, however, there are a whole host of other methods available. One such method is to use infrared lasers, ...

Metamaterial significantly enhances chiral nanoparticle signals

The left hand looks like the right hand in the mirror but the left-handed glove does not fit on the right hand. Chirality refers to this property where the object cannot be superimposed on to the mirror image. This property ...

Researchers improve semiconductor laser on silicon

Electrical engineering researchers have boosted the operating temperature of a promising new semiconductor laser on silicon substrate, moving it one step closer to possible commercial application.

How flawed diamonds 'lead' to flawless quantum networks

The color in a diamond comes from a defect, or "vacancy," where there is a missing carbon atom in the crystal lattice. Vacancies have long been of interest to electronics researchers because they can be used as 'quantum nodes' ...

New scientific concept for a Star Wars-like tractor beam

Physicists from ITMO University have developed a model of an optical tractor beam to capture particles based on new artificial materials. Such a beam is capable of moving particles or cells towards the radiation source. The ...
