Liquid foams are commonly used in our everyday life, such as beer, bathwater, cosmetics, hair products, and even in oil production. Foam is basically formed by a bunch of bubbles, and the key materials in the push for sustainability and energy efficiency are the lightweight dry foams made by bubbles squished together. To stabilize foams is very difficult, the traditional ways to stabilize them were to add surfactants, similar to detergents, or to add microscopic particles, such as talc power, but both methods could only work when the additive have specific properties, which is not always possible, so the new study conducted by George Tech was aiming to solve these problems, and the new type of foam they developed is called capillary foam, which can be stable by using combined presence of particles and a small amount of oil in water-based foams, but neither the particles nor the oil can stabilize the foams alone.
