Iodide salts stabilise biocatalysts for fuel cells
18-Feb-2020
Oxygen is the greatest enemy of biocatalysts for energy conversion. A protective film shields them – but only with an additional ingredient: iodide salt. Contrary to theoretical predictions, oxygen inactivates biocatalysts for energy conversion within a short time, even under a protective film. A ...
Observing proteins in their natural environment
11-Feb-2020
Proteins can be responsible for the fact that the active ingredients of drugs are simply released from the target cells. You can watch them do this now. Certain medications, such as those used to treat cancer, lose their effect because proteins in the membrane of the target cell simply expel them ...
New findings on the recycling centres of cells
11-Oct-2019
Like tiny garbage chutes, certain organelles clean cells of superfluous or defective material. Researchers are currently studying the mechanisms underlying this process. Both animal and plant cells depend on their own damaged or superfluous cell material being removed – a process referred to as ...
New approaches to heal injured nerves
27-Aug-2019
Preventing the deactivation of a protein could be the key to repairing the central nervous system. Injuries to nerve fibers in the brain, spinal cord, and optic nerves usually result in functional losses as the nerve fibers are unable to regenerate. A team from the Department of Cell Physiology ...
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 ...
q&more – the networking platform for quality excellence in lab and process
The q&more concept is to increase the visibility of recent research and innovative solutions, and support the exchange of knowledge. In the broad spectrum of subjects covered, the focus is on achieving maximum quality in highly innovative sectors. As a modern knowledge platform, q&more offers market participants one-of-a-kind networking opportunities. Cutting-edge research is presented by authors of international repute. Attractively presented in a high-quality context, and published in German and English, the original articles introduce new concepts and highlight unconventional solution strategies.
