Behrooz’s comment now available

Last year, an interesting article came out discussing how droplets on PDMS brushes move faster when the gas phase is solvent vapour rather than air. This was attributed to swelling of the brushes by the solvent. Behrooz has a different, simpler explanation: simple surface energies. We made a Comment on their work, which has now been published in Advanced Materials. Check it out here.

Excellent work Behrooz!
