öntisztítás

Öntisztítás is a Finnish term that translates to self-cleaning. In a biological context, it refers to the inherent ability of organisms to maintain their internal environment and remove waste products. This process is crucial for survival and involves various physiological mechanisms. For example, the human body utilizes organs like the kidneys and liver to filter blood and excrete toxins. Skin shedding is another form of self-cleaning, removing dead cells and preventing the buildup of harmful substances.

In the realm of technology and engineering, öntisztítás describes the self-cleaning properties of certain materials or devices. Surfaces designed with öntisztítás capabilities can repel dirt, water, or other contaminants, reducing the need for manual cleaning. This can be achieved through various methods, such as photocatalysis, where UV light activates a coating to break down organic matter, or superhydrophobic surfaces that cause water droplets to roll off, taking dirt with them. Examples include self-cleaning windows, solar panels, and some textiles. The concept aims to improve hygiene, reduce maintenance, and enhance the longevity of products.
