Itsesäteileviä

Itsesäteileviä is a Finnish term that translates to "self-sealing" in English. It refers to a characteristic of a material or a system that has the ability to automatically repair or close small breaches or leaks. This property is often achieved through the inclusion of specific components within the material that are activated by damage.

For example, in the context of materials science, self-sealing capabilities can be engineered into polymers or composites. These materials might contain microcapsules filled with a healing agent. When a crack forms, these capsules rupture, releasing the agent which then polymerizes or reacts to fill and seal the damage. This process can restore the structural integrity and prevent further leakage.

The concept of self-sealing is also applicable in biological systems, where certain tissues or fluids can naturally clot or seal wounds. In engineering, self-sealing designs are used in various applications, such as tires, hoses, and protective coatings, to enhance durability and prevent failures caused by minor punctures or wear. The primary benefit of itsesäteileviä is the extended lifespan and improved reliability of the object or system in question, as it can maintain its function even after experiencing minor damage.
