The bioactivity of most near-infrared II (NIRII) fluorophores are limited, thereby conflicting the achievement of strong fluorescence and high catalytic activities, due to a lack of free electrons in the method.
Using the LOw Frequency ARray (LOFAR), astronomers from the University of Bologna, Italy and elsewhere, have conducted radio observations of the nearby galaxy cluster Abell 2142. In result, they detected a new component of ...
