Sentences with phrase «molecules stick to the surface»

All of these molecules stick to the surface of dust specks, accumulating icy layers over millions of years.

Not exact matches

Water molecules move from areas of low surface tension to high surface tension and so the sticks moved.

The trick is, as we mentioned earlier, the ability of water molecules to stick to each other and to other surfaces so strongly.

As a result, water molecules tend to stick to one another; that adhesion is why water forms rounded droplets on a smooth surface and does not spread out into a completely flat film.

Until now, geckos were thought to be able to stick to surfaces using van der Waals forces, the weak attraction resulting from the temporary movement of charged particles within a molecule.

When the molecules are dissimilar, as in the case of a glue molecule and a molecule of the substrate (the surface the glue is sticking to), the adhesive force holds the glue to the substrate.

«Various forms of carbon, including nanotubes, are considered for hydrogen or other fuel storage because they have a huge internal surface area for the fuel molecules to stick to.

Adsorption occurs when molecules essentially stick to a surface.

The researchers created a hybrid compound from 2 molecules: LLP2A, a protein - like molecule that sticks to α4β1 integrins, and alendronate, an osteoporosis drug that sticks to the outer surface of bones.

Furthermore, the instrument can be employed to measure the force between the tip and a surface, and in some cases even the force between a molecule stuck to the tip and other molecules in a biological tissue.

When the surface was negatively charged, some water molecules became stuck to the surface, while other water molecules became disordered and moved away from the surface.
