The present system is a new example of bifurcation in reactions of closed-shell molecules. The overall reaction mechanism changes dynamically from E2 to E1cb by a gradual change in the ratio of E2 and E1cb trajectories, rather than a path switch in concurrent pathways.doi:10.1002/chem.201001926...

Fireflies are a fascinating example of bioluminescent organisms. They produce light through a chemical reaction in their bodies, which is a pretty cool adaptation for attracting mates.This ability to produce light is a result of a complex process involving the enzyme luciferase and a molecule called...
The reaction system hydrogen peroxide-thiosulfate-sulfite in diluted sulfuric acid (HPTS) displays strongly nonlinear dynamics when operated in a continuous-flow stirred tank reactor. Due to a crucial role of hydrogen ion during the reaction, this system is a prime example of an inorganic pH-oscill...
For example, "Lock screen transparent" or "Lock screen shows activities". If you find that a bug report already exists, select the "Add your Reaction" button (it looks like a smiley face) and select the +1 (thumbs up) reaction. This shows that you are also experiencing the bug. If ...
