Researchers dramatically downsize technology for fingerprinting drugs and other chemicals

Tiny photonic chip could fit comfortably within the tip of a finger

01-Sep-2020 - As new infectious diseases emerge and spread, one of the best shots against novel pathogens is finding new medicines or vaccines. But before drugs can be used as potential cures, they have to be painstakingly screened for composition, safety and purity, among other things. Thus, there is an ...

New device can measure toxic lead within minutes

Researchers create portable lab-on-a-chip that could detect many contaminants

28-Aug-2020 - Rutgers researchers have created a miniature device for measuring trace levels of toxic lead in sediments at the bottom of harbors, rivers and other waterways within minutes - far faster than currently available laboratory-based tests, which take days. The affordable lab-on-a-chip device could ...

Electron movements in liquid measured in super-slow motion

“Electron movements are the key events in chemical reactions”

24-Aug-2020 - 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 ...

Atoms at the photo shoot

Scientists photographed, for the first time, individual atoms floating less than a thousandth of a millimeter above a light-conducting glass fiber

06-Aug-2020 - The first photograph of a single trapped atom represented a milestone for quantum research. This breakthrough was made possible because the atom was captured in a vacuum using electric fields and held far from surfaces whose scattered light could blind the camera. Scientists at Humboldt ...

New depths in infrared nanospectroscopy

Subsurface chemical nanoidentification by nano-FTIR spectroscopy

31-Jul-2020 - Researchers from the Nanooptics Group at CIC nanoGUNE (San Sebastian) demonstrate that nanoscale infrared imaging - which is established as a surface-sensitive technique - can be employed for chemical nanoidentification of materials that are located up to 100 nm below the surface. The results ...

Microplastics transport metallic pollutants

Pursuing the Trojan horse: Scientists are developing methods for measuring metal in microplastics

27-Jul-2020 - There are a relatively large number of studies on the accumulation and transport of persistent organic pollutants by microplastics, which has resulted in good data in this regard. Data, however, on the accumulation of metals that are toxic to the environment are very rare and sometimes ...

New ‘super light source’ should allow fascinating insights into atoms

‘Gamma Factory’ will enable not only breakthroughs in spectroscopy but also novel ways of testing fundamental symmetries of nature

24-Jul-2020 - The ‘Gamma Factory initiative’ – an international team of scientists – is currently exploring a novel research tool: They propose to develop a source of high-intensity gamma rays using the existing accelerator facilities at CERN. To do this, specialized ion beams will be circulated in the SPS and ...
