An evaporating colloidal particle–laden droplet leaves behind a ring-like residue after drying. We routinely observe this ubiquitous phenomenon for dried coffee drops; thus, it is known as the "coffee ...

AMONG the reactions which have proved of value in the investigations of the effects of substituents on reaction-rates in solution is the one between organic chlorides and metallic iodides in ...

Steady-state and picosecond time-resolved emission spectroscopy are used to monitor the bimolecular electron transfer reaction between the electron acceptor 9,10-dicyanoanthracene in its S1 state and ...

Fenton process and activated carbon are widely used for water treatment, yet both encounter significant challenges, such as slow Fe3+/Fe2+ conversion and rapid adsorbent saturation. Herein, a category ...
