Visible‐Light Photoswitching by Azobenzazoles
Chemistry – A European Journal, 2020 AbstractThree visible‐light responsive photoswitches are reported, azobis(1‐methyl‐benzimidazole) (1), azobis(benzoxazole) (2) and azobis(benzothiazole) (3). Photostationary distributions are obtained upon irradiation with visible light comprising approximately 80 % of the thermally unstable isomer, with thermal half‐lives up to 8 min and are mostly ...

Sensitivity of Hands to Visible Light [PDF]
Nature, 1964 RECENTLY, reports have appeared in the press of experiments demonstrating the existence of a dermal sensitivity to intensities and wave-lengths of visible light. Many of the experiments do not appear to have precluded thermal effects, and B. Konstantinov has suggested1 that the results may be explained by the perception of reflected infra-red radiation

FEBS Letters, EarlyView.Enteropathogenic E. coli (EPEC) infects the human intestinal epithelium, resulting in severe illness and diarrhoea. In this study, we compared the infection of cancer‐derived cell lines with human organoid‐derived models of the small intestine. We observed a delayed in attachment, inflammation and cell death on primary cells, indicating that host ...
