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 ...

Vapor pressure and saturated liquid density for HFO–1234ze(E) and HFO–1234ze(Z) were measured in the temperature range from 300 to 400 K by using the extraction method. Experimental uncertainties are ...
