Durable, inexpensive catalyst reduces carbon footprint of ammonia production


The Haber-Bosch process, which is commonly used to synthesize ammonia (NH3)–the foundation for synthetic nitrogen fertilizers–by combining hydrogen (H2) and nitrogen (N2) over catalysts at high pressures and temperatures, is one of the most important scientific discoveries that has helped improve ...

Batteries without critical raw materials

Berlin based research group "operando battery analysis" has developed new cell chemistry


The market for rechargeable batteries is growing rapidly, but the necessary raw materials are limited. Sodium-ion batteries, for example, could offer an alternative. A joint research group from HZB and Humboldt-Universität zu Berlin has investigated new combinations of electrolyte solutions and ...

High entropy alloys: structural disorder and magnetic properties

"High-entropy alloys are an extremely diverse and exciting class of materials”


High-entropy alloys (HEAs) are promising materials for catalysis and energy storage, and at the same time they are extremely hard, heat resistant and demonstrate great variability in their magnetic behaviour. Now, a team at BESSY II in collaboration with Ruhr University Bochum, BAM, Freie ...

The Sound of COVID-19

Researchers in Luxembourg discover how to use vocal biomarkers to monitor COVID-19


The Predi-COVID Cohort study, a project led by Dr Guy Fagherazzi of the Luxembourg Institute of Health, showed for the first time that vocal recordings of COVID-19 affected people could be used to monitor related symptoms of the disease. This new biomarker-based technology could become a novel ...

Molecular structure of one of the most important receptors in the immune system unraveled

Researchers publish the three-dimensional structure of the B cell antigen receptor, shedding new light on its composition


The surface of B cells is covered with antigen receptors with which they recognize invading pathogens such as bacteria and viruses. When a B cell receptor binds to an antigen, that is, to a foreign structure, the B cell is activated and triggers the production of antibodies. Antibodies are ...

Light-driven molecular swing

Scientists have used ultrashort laser pulses to make the atoms of molecules vibrate and have gained a precise understanding of the dynamics of energy transfer


When light impinges on molecules, it is absorbed and re-emitted. Advances in ultrafast laser technology have steadily improved the level of detail in studies of such light-matter interactions. FRS, a laser spectroscopy method in which the electric field of laser pulses repeating millions of times ...

Secret structure in the wiring diagram of the brain

Researchers discover a hidden order in seemingly random connections between neurons


In the brain, our perception arises from a complex interplay of neurons that are connected via synapses. But the number and strength of connections between certain types of neurons can vary. Researchers from the University Hospital Bonn (UKB), the University Medical Center Mainz and the ...

Gene activity in a test tube

An accurate picture of gene activity can provide the key to the development of new, targeted therapies


When searching for the causes of illnesses and developing new treatments, it is absolutely vital to have a precise understanding of the genetic fundamentals. Würzburg researchers have devised a new technique for this purpose. Pathological processes are usually characterised by altered gene ...

Back to the Future of Photosynthesis

Scientific journeys back in time can provide invaluable insights for the future


The central biocatalyst in Photosynthesis, Rubisco, is the most abundant enzyme on earth. But how did Rubisco evolve, and how did it adapt to environmental changes during Earth’s history? By reconstructing billion-year-old enzymes, a team of Max Planck Researchers has deciphered one of the key ...

A crystalline attoclock

Physicists measure the dynamics of mobile electrons in solids with unprecedented time resolution


From experience, driving through the city centre takes longer than covering the same distance on an open country road. After all, you will encounter a lot of other road users, red lights, road works and traffic jams in the city centre. Conversely, if you want to find out how busy a road is ...
