A direct observation of up-converted room-temperature phosphorescence in an anti-Kasha dopant-matrix system
It is common sense that emission maxima of phosphorescence spectra (λP) are longer than those of fluorescence spectra (λF). We report a serendipitous finding of up-converted room-temperature phosphorescence with λP < λF and phosphorescence lifetime > 0.1 s in dopant-matrix systems.
Selective activation of C–F bond in organic fluorides under mild and transition-metal-free conditions: From carbosilylation of alkenes to defluoroamination
SNACIP: small molecule-nanobody conjugate induced proximity controls intracellular processes and modulates endogenous unligandable targets
Extreme weather events impact countries' economies. To increase financial resilience against such events, some countries joined sovereign catastrophe risk pools. The risk diversification of these pools - and their member countries' financial resilience - can significantly increase via global pooling.
Increased impact of heat domes on 2021-like North American heat extremes due to background warming and soil moisture feedback
The heat dome explains over 50% of 2021 Western North American high temperature. The impact of heat domes on the intensities of 2021-like North American heat extremes have and will continue to increase due to both the background warming and soil moisture feedback.
A more equitable global distribution of vaccines can benefit the world, while a multilateral benefit-sharing instrument needs to be developed to remove some of the disincentives for early equitable vaccine distribution globally.
