WebTantalum Foam (Ta Foam) is a porous 3-dimensional structure made of tantalum. Due to the nontoxic, biocompatible, good corrosion resistant, and high thermal conductive properties, Tantalum Foam is often used as one of the porous materials used in the clinical study. Metal tantalum features non-toxicity, high corrosion resistance, and good ... WebYou probably saw lots of bubbles and foam in this activity. What made the foam appear? The answer is, when the enzyme catalase comes in contact with its substrate, hydrogen peroxide, it starts breaking it down into water and oxygen. Oxygen is a gas and therefore wants to escape the liquid.
