Surfactant‐mediated electro‐dewetting of droplets in oil for liquid‐shape manipulation

Droplet, Volume 4, Issue 4, October 2025.
Surfactant‐mediated electro‐dewetting has recently been demonstrated to manipulate droplets in air for digital microfluidics. The current work explores electro‐dewetting of droplets in oil for liquid‐shape manipulation. Contact‐angle change of 100° is obtained for electro‐dewetting of a dimethyl sulfoxide droplet in hexadecane oil with mere 4 V.

A Direct and Practical Approach to Assessing the Impact of Emulsion Composition on Vitamin A Stability

Journal of the American Oil Chemists' Society, Volume 102, Issue 9, Page 1425-1437, September 2025.
ABSTRACT Vitamin A is an essential micronutrient involved in vision, immunity, and growth. Despite its widespread use in food, cosmetic, and pharmaceutical products, vitamin A is highly prone to oxidation due to its conjugated double bonds, leading to reduced biological activity and efficacy.

The aqueous cationic system sodium undecenoate-dodecyltrimethylammonium bromide at low concentration [PDF]

, 2004
The aqueous sodium undecenoate (SUD) -dodecyltrimethylammonium bromide (DTAB) catanionic system was studied at low concentration. The system did not precipitate, even at a 1:1 SUD:DTAB proportion, but showed the formation of a coacervate in a range of ...
