Nanostructures help to reduce the adhesion of bacteria

Scientists have shown how bacteria adhere to rough surfaces at the microscopic level. Now a team of researchers has discovered that precise analysis of the topographical composition of nanostructured surfaces provides a direct ...

The journey of pollen and the process of pollen dispersal

For allergy sufferers, the pollination period is a tough time, whereas for plants it is the opportunity to reproduce: in addition to the wind, insects, in particular, carry pollen from one flower to another to pollinate them. ...

Amoeba builds barriers for protection against bacteria

In some respects, animals and amoebae are not that different. For instance, both are at risk of potentially deadly attacks by bacteria and have evolved ways to prevent them. Researchers at Baylor College of Medicine report ...

Adhesion

Adhesion is any attraction process between dissimilar molecular species that can potentially bring them in close contact. By contrast, cohesion takes place between similar molecules.

Adhesion is the tendency of dissimilar particles and/or surfaces to cling to one another (cohesion refers to the tendency of similar or identical particles/surfaces to cling to one another). The forces that cause adhesion and cohesion can be divided into several types. The intermolecular forces responsible for the function of various kinds of stickers and sticky tape fall into the categories of chemical adhesion, dispersive adhesion, and diffusive adhesion. In addition to the cumulative magnitudes of these intermolecular forces, there are certain emergent mechanical effects that will also be discussed at the end of the article.
