Good catalytic performance is driven chiefly by processes that occur on the surface of the catalyst – and not electrochemical processes
Splitting water into hydrogen and oxygen is an important chemical reaction, especially considering that the use of hydrogen as an energy source in sustainable mobility in the future. An international research team has now decoded how one of the catalysts used in this reaction works. Hydrogen is a ...
Findings will help catalyst research take an important step forward
“Titanium silicalite-1” (TS-1) is not a new catalyst: It has been almost 40 years since its development and the discovery of its ability to convert propylene into propylene oxide, an important basic chemical in the chemical industry. Now, by combining various methods, a team of scientists from ...
A starting point for vaccine and drug development
Researchers at ETH Zurich and the University of Bern have discovered a mechanism by which the corona virus manipulates human cells to ensure its own replication. This knowledge will help to develop drugs and vaccines against the corona virus. Like a pirate hijacking a ship, a virus takes control ...
Two binding modes allow bacteria to stick to surfaces under flow
Researchers have revealed a new molecular mechanism by which bacteria adhere to cellulose fibers in the human gut. Thanks to two different binding modes, they can withstand the shear forces in the body. Scientists of the University of Basel and ETH Zurich published their results in the journal ...
“Electron movements are the key events in chemical reactions”
Electrons are able to move within molecules, for example when they are excited from outside or in the course of a chemical reaction. For the first time, scientists have now succeeded in studying the first few dozen attoseconds of this electron movement in a liquid. To understand how chemical ...
"We have created one of the largest databases of transistor materials"
Since the discovery of graphene, two-dimensional materials have been the focus of materials research. Among other things, they could be used to build tiny, high-performance transistors. Researchers at ETH Zurich and EPF Lausanne have now simulated and evaluated one hundred possible materials ...
Short double-stranded RNA fragments “transmits” RNA interference
Biologists have known for some time that RNA interference can silence genes in far-off cells. They suspected that a messenger substance “transmits” RNA interference. Now, ETH researchers have definitively shown that these messengers in plants are short double-stranded RNA fragments. In most ...
How the dispersity of a plastic can be completely controlled by mixing two catalysts
ETH researchers have developed a new method for producing polymers with different lengths. This paves the way for new classes of polymer materials to be used in previously inconceivable applications. It is hard to imagine everyday life without materials made of synthetic polymers. Clothes, car ...
Basis for medical implants that can be switched on and off using electronic devices outside the body
A team of researchers led by ETH professor Martin Fussenegger has succeeded in using an electric current to directly control gene expression for the first time. Their work provides the basis for medical implants that can be switched on and off using electronic devices outside the body. This is ...
Instructing cells to grow in a particular direction is a long-cherished dream
ETH researchers have developed a new method in which they use light to draw patterns of molecules that guide living cells. The approach allows for a closer look at the development of multicellular organisms – and in the future may even play a part in novel therapies. Highly complex organisms can ...
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.
