  摘要：Cells display a range of mechanical activities generated by motor proteins powered through catalysis1. This raises the fundamental question of how the acceleration of a chemical reaction can enable the energy released from that reaction to be transduced (and, consequently, work to be done) by a molecular catalyst2, 3, 4, 5, 6-7. Here we demonstrate the molecular-level transduction of chemical energy to mechanical force8 in the form of the powered contraction and powered re-expansion of a cross...

  摘要：Organic halides are highly useful compounds in chemical synthesis, in which the halide serves as a versatile functional group for elimination, substitution and cross-coupling reactions with transition metals or photocatalysis1, 2-3. However, the activation of carbon-fluorine (C-F) bonds-the most commercially abundant organohalide and found in polyfluoroalkyl substances (PFAS), or 'forever chemicals'-is much rarer. Current approaches based on photoredox chemistry for the activation of small-mol...
