The quantum refrigerator
Computer simulations show how quantum fields could be used to break low-temperature records
30-Jul-2021
At first glance, heat and cold don't have much to do with quantum physics. A single atom is neither hot nor cold. Temperature can only be defined for objects that consist of many particles. But at TU Wien, in collaboration with Freie Universität Berlin, Nanyang Technological University in ...
Fastest sensor for heat flow tested
Relevant for alternative fuels and hydrogen
30-Jul-2021
A team of researchers from the Faculty of Mechanical Engineering at Landshut University of Applied Sciences has developed a new method to measure the heat flow in combustion engines faster than before. The technique could help reduce pollutant emissions in the future. It is also relevant for the ...
How diphosphorus can be used for chemical reactions
Team from Göttingen and Frankfurt succeeds in stabilisation
29-Jul-2021
Chemical syntheses of new active ingredients or functional materials are based on the use of molecular building blocks. These must be simultaneously reactive but also stable enough to enable targeted incorporation into larger molecules. A research team from the University of Göttingen and the ...
Infrared in the heel
A chromium complex as NIR-II emitter
29-Jul-2021
Substances that emit light in the near infrared (NIR) range are needed for a wide variety of applications, from fibre-optic telecommunications to imaging techniques for biomedicine. A Swiss research team has now for the first time developed a chromium complex that emits light in the coveted ...
Lead-free perovskite solar cells
How fluorine additives improve quality
29-Jul-2021
Tin halide perovskites are currently considered the best alternative to lead-containing analogues, but are still significantly less efficient and stable compared to them. Now, a team led by Prof. Antonio Abate from HZB has analysed the chemical processes in the perovskite precursor solution and ...
The memory of folds
What happens when soft materials are compressed strongly?
28-Jul-2021
Researchers from the Max Planck Institute for Dynamic and Self-Organization, the University of Twente and Cornell University now revealed the morphology of creases created upon folding at micrometer scale. They revealed a dual folding mechanism driven by capillary forces, similar to wetting ...
Artificial intelligence: Swarm learning decodes biomolecules
28-Jul-2021
They are often referred to as the "building blocks of life": Biomolecules. To understand and use their function in the body, one must know their structure. A complex and sometimes imprecise matter. This is where the new method developed at the University of Duisburg-Essen (UDE) together with ...
Random effects make it difficult to optimise antibiotic therapy
Research team from the Kiel Evolution Center investigates the role of a reduction in bacterial population size and resulting random effects in the evolution of antibiotic resistance
28-Jul-2021
Antibiotic-resistant pathogens have become one of the greatest threats to public health. In just a few years, previously harmless bacterial infections may no longer be treatable and may once again become a leading non-natural cause of death, as they were before the antibiotic era began until the ...
Resource-efficient and cost-effective wear-resistant coatings thanks to new hybrid coating process
Hardness increases of up to 30 percent
28-Jul-2021
A team of researchers at the Fraunhofer Institute for Production Technology IPT in Aachen has developed a hybrid additive manufacturing process that combines wire-based and powder-based laser cladding (LMD). The new process can be used to apply protective coatings of high-strength tool steel to ...
New US and German collaboration aims to produce green hydrogen more efficiently
NSF-DFG EChem Award Announcement
27-Jul-2021
Through a new award program, the U.S. National Science Foundation and the Deutsche Forschungsgemeinschaft (German Research Foundation, DFG) have joined forces to award the University of Illinois Urbana-Champaign and Technical University of Darmstadt a three-year $720,000 research grant ($500,000 ...
