Have you ever experienced the strange taste of water after it has been in a reusable plastic bottle for a while?
Researchers at the University of Copenhagen have found several hundred different chemical substances in tap water stored in reusable plastic bottles. Several of these substances are potentially harmful to human health. There is a need for better regulation and manufacturing standards for ...
Machines can distinguish 12 different types of plastic thereby separate plastics according to their chemical composition
In contrast to common perceptions, plastic is in no way near one material. Rather, it is a combination of many materials (polymers) with different chemical compounds and additives such as pigments or fibres, depending on its use. It is very difficult to tell the difference between different types ...
Chemically synthesized short DNA sequences are extremely important ingredients with countless uses
The DNA sequences produced are also called oligonucleotides. These are widely used for disease identification, for the manufacture of oligonucleotide-based drugs, and for several other medical and biotechnological applications. The high demand for oligonucleotides therefore requires an efficient ...
New research suggests that more than 100 chemicals found in plastic toy materials may pose possible health risks to children
It has long been known that several chemicals used in plastic toys in different parts of the world can be harmful to human health. However, it is difficult for parents to figure out how to avoid plastic toys containing chemicals that may cause possible health risks to their children. Regulations ...
Researchers have succeeded to obtain control of the molecular machines, which in the future may enable them to perform controlled movements
Molecules are some of life's most basic building blocks. When they work together in the right way, they become molecular machines that can solve the most amazing tasks. They are essential for all organisms by, for example, maintaining a wide range of cellular functions and mechanisms. What if you ...
Quantum research unifies two ideas offering an alternative route to topological superconductivity
A pencil shaped semiconductor, measuring only a few hundred nanometers in diameter, is what researches from the Center for Quantum Devices, Niels Bohr Institute, at University of Copenhagen, in collaboration with Microsoft Quantum researchers, have used to uncover a new route to topological ...
We all know the rechargeable and efficient lithium ion (Li-ion) batteries sitting in our smartphones, laptops and also in electric cars. Unfortunately, lithium is a limited resource, so it will be a challenge to satisfy the worlds' growing demand for relatively cheap batteries. Therefore, ...
Determination of the crystal structure of a DNA-stabilized silver nanocluster
Nanoclusters are little “heaps” of a few atoms that often have interesting optical properties and could become useful probes for imaging processes in areas such as biomedicine and diagnostics. In the journal Angewandte Chemie, researchers have introduced a nanocluster of 16 silver atoms ...
The chemical element sulfur is an important constituent in many pharmaceuticals and, consequently, it is desirable to be able to introduce sulfur-containing fragments efficiently in a broad range of chemical compounds. The Skrydstrup team provides an effective and safe way for introducing a ...
”Normally it’s not a huge success that not a damn thing has happened after 120 days.” These words belong to Professor Peter Bøggild after a four-month period where a novel type of anticorrosion coating was tested. The nanomaterial graphene plays a crucial role in this new type of coating. ...
