Super quick COVID test uses new technology

The ability of gold particles to reflect light in different colours is used in applications from stained glass to pregnancy tests. Now researchers are set to exploit the same properties in an ultra-fast sensor for the coronavirus.

Hermann Göring’s Luftwaffe and the $6 billion deal

How the unlikely combination of WWII Germany, a modest English engineer who created a worker’s paradise, an ambitious industrialist prosecuted as a traitor and a hardworking PhD helped build modern Norway, one aluminium ingot at a time.

Nature’s colours can replace toxic pigments

Dye pigments are often toxic, so researchers around the world have long been looking for effective ways to make non-toxic, recyclable and sustainable colours instead. The answer lies in nanotechnology and nature’s own methods.

Hunting for dead stars

Neutron stars are the little siblings of black holes and show some of the most extreme phenomena in the universe. The European Research Council (ERC) is giving Professor Manuel Linares EUR 2 million to hunt them down.

Engineering materials for a new generation of electronics

Harnessing a fundamental property of electrons called spin could help create a new generation of computer chips and faster, more stable and less power hungry devices. NTNU researchers are studying a type of material that could make this technology feasible.

Super-strong magnetic supercrystals can assemble themselves

Materials scientists who work with nano-sized components have developed ways of working with their vanishingly small materials. But what if you could get your components to assemble themselves into different structures without actually handling them at all?
