Interfacial Characterization

---

 Our group investigates behavior at liquid-liquid, liquid-gas, and liquid-solid interfaces. One of our primary tools for our work is a high pressure (10,000 psia) interfacial tensiometer shown below.

 

We measure interfacial tension, elasticity, and contact angle at pressures up to 10,000 psia. For contact angle measurements, we have the ability to tilt the substrate in order to quantify advancing and receding contact angles.
