How two water molecules dance together
14-Aug-2019
Although water is omnipresent, the interaction between individual water molecules is not yet fully understood. An international research team has gained new insights into how water molecules interact. For the first time, the researchers were able to completely observe all of the movements between ...
High reaction rates even without precious metals
21-Jun-2019
Precious metals are often efficient catalysts. But they are expensive and rare. However, it has so far been difficult to determine how efficient non-precious metal alternatives are. Non-precious metal nanoparticles could one day replace expensive catalysts for hydrogen production. However, it is ...
Drug resistance: Preventing drugs from being transported
18-Jun-2019
Certain membrane proteins specialise in transporting molecules out of cells – a problem for the efficacy of cancer medication and antibiotics. An international research team has investigated the transport mechanism of a bacterial membrane protein using an artificially produced antibody fragment. ...
Monitoring the lifecycle of tiny catalyst nanoparticles
06-May-2019
Since they are so tiny, it is difficult to investigate single nanoparticles. However, this is exactly what researchers are aiming for in order to tailor their properties. A novel approach: particle at the stick. Nanoparticles can be used in many ways as catalysts. To be able to tailor them in ...
Alzheimer’s in mini brains
Verification in a living system
02-May-2019
The causes of the disease are for the most part obscure. Researchers intend to expose them using cerebral organoids grown from stem cells. In the majority of cases, dementia can be traced back to Alzheimer’s disease. Its causes are not really understood yet. What is known is that plaques form ...
How nerve cells control misfolded proteins
28-Mar-2019
Neurodegenerative diseases such as Huntington’s or Parkinson’s disease are associated with misfolded and aggregated proteins. Researchers have discovered a new mechanism used by cells to protect themselves. Researchers have identified a protein complex that marks misfolded proteins, stops them ...
Converting biomass by applying mechanical force
15-Mar-2019
One of the greatest global challenges is the efficient use of renewable sources in order to meet the increasing demand for energy and feedstock chemicals in the future. In this context, biomass is a promising alternative to existing fossil sources such as coal or oil. Cellulose plays a decisive ...
Next step on the path towards an efficient biofuel cell
Two concepts combined making system as efficient as precious metal catalysts
16-Nov-2018
Fuel cells that work with the enzyme hydrogenase are, in principle, just as efficient as those that contain the expensive precious metal platinum as a catalyst. However, the enzymes need an aqueous environment, which makes it difficult for the starting material for the reaction – hydrogen – to ...
Noble metal-free catalyst system as active as platinum
Affordable high-performance catalysts have come within reach
25-Oct-2018
The industry has been traditionally deploying platinum alloys as catalysts for oxygen reduction, which is for example essential in fuel cells or metal-air batteries. Expensive and rare, that metal imposes strict restrictions on manufacture. Researchers at Ruhr-Universität Bochum (RUB) and ...
New insights into the structure of a killer protein
01-Oct-2018
The protein Bax is responsible for programmed cell death. Because it is constantly changing its location, its structure has so far been difficult to determine. Researchers at Ruhr-Universität Bochum and the University of Tübingen have gained new insights into the structure of the killer protein ...
q&more – the networking platform for quality excellence in lab and process
