Challenging counterfeit products with rare earths

New marking technique could halt product piracy


Researchers at the University of Copenhagen have developed the world's most secure marking system for combatting pirated goods including pirated pharmaceuticals, foodstuffs, designer merchandise and artwork. The system could be on the market in a year and because the markings are random, it ...

Breakthrough in electrochemical production of hydrogen peroxide

Evonik invests in Danish hydrogen peroxide start-up


Evonik has invested in the startup HPNow ApS through its venture capital unit and now holds a minority stake in the company, which is headquartered in Copenhagen (Denmark). HPNow has developed a technology for producing hydrogen peroxide (H2O2) in a fully automatic system using water, air, and an ...

New model makes us wiser on cocktail effects


The ability of chemical combinations to precipitate a cocktail effect is acknowledged. We can also calculate the impacts of various chemical products ranging from shampoos to pesticides. However, critical exceptions add uncertainty to these calculations. One group of chemicals, known as ...


A patent-free playground

Researchers and industrial companies collaborate to create a new Open Science platform


Along with a number of leading Danish industrial companies, Aarhus University has opted out of the patent rat race in a new collaboration on industrially relevant basic research. Researchers and companies from all over Denmark publish all their results and data on the innovative Open Science ...

Smart atomic cloud solves Heisenberg's observation problem


Quantum physics: Scientists at the Niels Bohr Institute by University of Copenhagen have been instrumental in developing a 'hands-on' answer to a challenge intricately linked to a very fundamental principle in physics: Heisenberg's Uncertainty Principle. The NBI-researchers used laser light to ...

First step towards photonic quantum network


Advanced photonic nanostructures are well on their way to revolutionising quantum technology for quantum networks based on light. Researchers from the Niels Bohr Institute have now developed the first building blocks needed to construct complex quantum photonic circuits for quantum networks. This ...

Superfast light source made from artificial atom


All light sources work by absorbing energy - for example, from an electric current - and emit energy as light. But the energy can also be lost as heat and it is therefore important that the light sources emit the light as quickly as possible, before the energy is lost as heat. Superfast light ...

Biotech breakthrough: Sunlight can be used to produce chemicals and energy


Researchers at the University of Copenhagen have discovered a natural process they describe as reverse photosynthesis. In the process, the energy in solar rays breaks down, rather than builds plant material, as is the case with photosynthesis. The sunlight is collected by chlorophyll, the same ...

New material lights up when detecting explosives


Scientists have created a material which turns fluorescent if there are molecules from explosives in the vicinity. The discovery could improve e.g. airport security - and also it gives us an insight into a rather chaotic micro-world where molecules and atoms constantly are responding to their ...


Harnessing the oxidising power of air


Researchers report the catalysis of a highly specific chemical reaction where oxygen from the air is one ingredient and the other, an organic molecule, is selectively "oxidised". A simple manganese compound catalyses this reaction. This type of methodology is an important step for the discovery ...
