Researchers create a photographic film of a molecular switch

Following the motion of a light-responsive molecule

22-Jun-2020

Molecular switches – they are the molecular counterparts of electrical switches and play an important role in many processes in nature. Such molecules can reversibly interconvert between two or more states and thereby control molecular processes. In living organisms, for example, they play a role ...

Triggered by light, a novel way to switch on an enzyme

Researchers identify enzyme which becomes catalytically active by light

28-May-2020

In living cells, enzymes drive biochemical metabolic processes enabling reactions to take place efficiently. It is this very ability which allows them to be used as catalysts in biotechnology, for example to create chemical products such as pharmaceutics. Researchers now identified an enzyme ...

Activating palladium catalysis by light: teaching an old transition metal new tricks

Chemists develop method to produce π-allylpalladium complexes by radical chemistry

26-Mar-2020

In the production of compounds, chemists have the fundamental goal of finding strategies that are most selective and avoid waste products. Breakthroughs in this area serve, among other things, to drive industrial innovation and drug development. In this context, allylic substitution reactions ...

Predicting reaction results: Machines learn chemistry

Chemists and computer scientists develop artificial intelligence

19-Mar-2020

Everyday life without artificial intelligence is barely conceivable in today's world. Countless applications in areas such as autonomous driving, foreign language translations or medical diagnostics have found their way into our lives. In chemical research, too, great efforts are being made to ...

New insights into superconducting processes

Physicists demonstrate energy quantization in high-temperature superconductors

12-Feb-2020

The development of a quantum computer that can solve problems, which classical computers can only solve with great effort or not at all - this is the goal currently being pursued by an ever-growing number of research teams worldwide. The reason: Quantum effects, which originate from the world of ...

Otto-Roelen Medal for Frank Glorius

Highly innovative and efficient synthesis methods

11-Feb-2020

Prof. Frank Glorius from Westfälische Wilhelms-Universität Münster / Germany receives the Otto-Roelen Medal 2020. This prize will be awarded by DECHEMA and the German Catalysis Society in recognition of his developments in the field of chemo- and stereoselective hydrogenation of aromatics. The ...

Chemists allow boron atoms to migrate

Researchers present carbon-carbon couplings in which the semi-metal boron is retained

21-Jan-2020

Organic molecules with atoms of the semi-metal boron are among the most important building blocks for synthesis products that are needed to produce drugs and agricultural chemicals. However, during the usual chemical reactions used in industry, the valuable boron unit, which can replace another ...

Two chiral catalysts working hand in hand

Chemists develop a synthetic method providing access to different stereoisomers of a molecule

05-Dec-2019

Just as our left hand is not superposable to our right hand, the mirror image of certain molecules cannot be overlapped onto it, even when turned or twisted. These two mirror images are referred to by chemists as enantiomers and the molecule is said to be chiral. Chirality, which is a word ...

New method for using spin waves in magnetic materials

26-Nov-2019

Smaller, faster, more energy-efficient – this is the goal that developers of electronic devices have been working towards for years. In order to be able to miniaturize individual components of mobile phones or computers for example, magnetic waves are currently regarded as promising alternatives ...

Light to build biologically active compounds

Photocatalyst builds 3D scaffolds from flat aromatics

18-Nov-2019

Some of the most biologically active molecules, including synthetic drugs, contain a central, nitrogen-containing chemical structure called an isoquinuclidine. This core has a three-dimensional shape which means it has the potential to interact more favourably with enzymes and proteins than flat, ...
