In almost every industrial field there is rarely one phase of material involved. From suspensions to wetting phenomena, the interaction of a solid with a liquid, and frequently a gas, is dominated by surface chemistry, friction considerations and the environment. Understanding and testing interfacial tension, and how it varies with different surface tensions and preparations is vital for understanding how fluids wet surfaces. Likewise, understanding the action of surfactants, frequently behaving in a dynamic mode, is critical to understanding the stability of emulsions and suspensions, as well as the dynamics of spray or electrospinning processes. Our experts have backgrounds in colloids and surfaces, as well as extensional rheology and wetting phenomena.
