High-Performance Laser Mirrors Detect Trace Amounts of Substances in Gas Mixtures

High-Performance Laser Mirrors Detect Trace Amounts of Substances in Gas Mixtures
Written by AZoOpticsMay 19 2021
For the first time, physicists from the University of Vienna have successfully demonstrated high-performance laser mirrors in the sensing-relevant mid-infrared wavelength range. These mirrors absorb below 10 out of a million photons.

The study was performed in global cooperation with research and industry partners, which also involved Thorlabs, the National Institute of Standards and Technology (NIST), and the University of Kansas.
These low-loss mirrors, produced in a novel process based on crystalline materials, could pave the way to entirely new application fields, such as in optical respiratory gas analysis for the detection of greenhouse gases or the early detection of cancer. The study will be published in the cu ....

Researchers study the mechanisms of skin aging

Researchers study the mechanisms of skin aging
The aging process is most apparent on the skin. In the newly opened SKINMAGINE (Multimodal Imaging of Aging and Senescence of the Skin) Christian Doppler Laboratory, dermatologists from MedUni Vienna have joined forces with biotechnologists from the University of Natural Resources and Applied Life Sciences Vienna and chemists from Vienna University of Technology, as well as the company Chanel, to study the interaction of metabolism, cellular communication and cellular quality control in skin aging accelerated by environmental stress.
Skin aging does not happen in isolation but in interaction with the environment and changing processes in the body as a whole. It is accelerated by the urban exposome , the combined impact of factors such as environmental pollution and sunlight. Normal skin aging and skin aging accelerated by the urban lifestyle affect lipid, protein and glucose metabolism, the capacity for regeneration and com ....
