Foam superstabilization by polymer microrods.
TL;DR: It is reported how foams can be stabilized solely with a new class of anisotropic particles, hydrophobic polymer microrods of diameter less than 1 mum and length of a few tens of micrometers, which were extraordinary stable, retaining a constant volume over many days and even surviving drying of most of the free liquid.

Mechanisms of foam destruction by oil-based antifoams.
TL;DR: The experimental results show that two types of antifoam can be distinguished (called for brevity "fast" and "slow") which differ in the modes of their action, and the barrier preventing the emergence of pre-emulsified ant ifoam globules on the solution surface is of crucial importance for the mode of foam destruction and for the antIfoam efficiency.
