Important breakthrough in efficiently merging microrobotics and imaging
16-May-2022
Microrobots have the potential to revolutionize medicine. Researchers at the Max Planck ETH Centre for Learning Systems have now developed an imaging technique that for the first time recognises cell-sized microrobots individually and at high resolution in a living organism. How can a blood clot ...
On-line chemical ionization techniques for high sensitivity and in situ small molecule detection for stationary and mobile analysis
11-May-2022
Bruker Corporation and TOFWERK AG announced a strategic partnership for high-speed, ultra-sensitive applied and industrial analytical solutions, in conjunction with a Bruker minority investment in TOFWERK. The partnership provides a basis for technology collaborations to advance instrument ...
A team from the UNIGE has succeeded in visualizing crystal nucleation - the stage that precedes crystallization - that was invisible until now
26-Apr-2022
At the interface between chemistry and physics, the process of crystallization is omnipresent in nature and industry. It is the basis for the formation of snowflakes but also of certain active ingredients used in pharmacology. For the phenomenon to occur for a given substance, it must first go ...
Temporal sequence of photochemical reaction in individual aerosol particles observed with high resolution
21-Apr-2022
Aerosols in the atmosphere react to incident sunlight. This light is amplified in the interior of the aerosol droplets and particles, accelerating reactions. ETH researchers have now been able to demonstrate and quantify this effect and recommend factoring it into future climate models. Liquid ...
Opportunities for a "new" chemistry
20-Apr-2022
Chemical syntheses in liquids and gases take place in three-dimensional space. Random collisions between molecules have to result in something new in an extremely short time. But there is another way: on a gold surface under ultrahigh vacuum conditions, molecules lying still next to each other ...
"By combining the three fragments into one molecule, we hoped to enhance the effect, since the new molecule fills the binding pocket better"
14-Apr-2022
Researchers at the Paul Scherrer Institute PSI and the Italian Institute of Technology IIT have developed a novel substance that disables a protein in the cell skeleton, leading to cell death. In this way, substances of this type can prevent, for example, the growth of tumours. To accomplish ...
Researchers at PSI and ETH Zurich have observed for the first time how tiny magnets in a special layout align themselves solely as a result of temperature changes
06-Apr-2022
This view into processes that take place within so-called artificial spin ice could play an important role in the development of novel high-performance computers. When water freezes to form ice, the water molecules, with their hydrogen and oxygen atoms, arrange themselves in a complex ...
In vitro mast cells provide unprecedented reliability
23-Mar-2022
Although allergies are widespread, their diagnosis is complex and, depending on the type of allergy, the prospects of success with therapy are not always clear. Skin tests so far have been unpleasant, time-consuming and associated with a certain risk of triggering an allergic overreaction. ...
Together with spin-off XRnanotech, PSI plans to market the new lens
16-Mar-2022
PSI scientists have developed a ground-breaking achromatic lens for X-rays. This allows the X-ray beams to be accurately focused on a single point even if they have different wavelengths. The new lens will make it much easier to study nanostructures using X-rays, according to a paper just ...
Bacteria show great promise as a source of active ingredients
17-Feb-2022
Using computer-based genome analysis, researchers at ETH Zurich have now discovered a new class of natural products that might one day serve as antibiotics. Animals, plants, fungi and bacteria – each and every organism carries a whole armoury of chemical compounds that enable it to interact with ...
