In the present study, we introduced the nitrogenated heterocycles and fluorine atoms into the 2,5′-dibromo-4,5,2′-trihydroxyl diphenylmethanone (LM49), a bromophenol analog previously reported for its strong antioxidant ability involving in the Keap1–Nrf2 pathway. Twenty-seven fluorophenols 6a–6g, 8a–8k, 10a–10g, and 12a–12b were prepared, evaluated for their antioxidant activity in EA.hy926 cells,...
Many uncertainties are introduced inevitably during estimating fire risk for life safety in buildings. Probabilistic methods, the most widely used method to deal with uncertainties, require a large number of historical data. Due to the uniqueness of building fires, such data are rarely available. In order to address this limitation, a fuzzy risk assessment method for life safety under building fires...
In this paper a kind of hollow-core terahertz photonic crystal fiber made of Cyclic-olefin Copolymer with low absorption loss is designed. Results show these fibers are much better than metallic waveguides for their fine transmission properties in terahertz band. Along with the fine flexibility to bend, they are of great importance in application.
