News: Just seven photons can act like billions


A system made of just a handful of particles acts just like larger systems, allowing scientists to study quantum behaviour more easily.

Most substances physicists study are made up of huge numbers of particles -- so large that there is essentially no difference between the behavioural properties of a drop or a swimming pool's worth of pure water. Even a single drop can contain more than a quadrillion particles.

News: Solar power: Golden sandwich could make the world more sustainable


Scientists have developed a photoelectrode that can harvest 85 percent of visible light in a 30 nanometers-thin semiconductor layer between gold layers, converting light energy 11 times more efficiently than previous methods.

In the pursuit of realizing a sustainable society, there is an ever-increasing demand to develop revolutionary solar cells or artificial photosynthesis systems that utilize visible light energy from the sun while using as few materials as possible.

News: Novel nano material for quantum electronics


An international team led by Assistant Professor Kasper Steen Pedersen, DTU Chemistry, has synthesized a novel nano material with electrical and magnetic properties making it suitable for future quantum computers and other applications in electronics.

Chromium-Chloride-Pyrazine (chemical formula CrCl2(pyrazine)2) is a layered material, which is a precursor for a so-called 2D material. In principle, a 2D material has a thickness of just a single molecule and this often leads to properties very different from those of the same material in a normal 3D……
