A complex interplay of energetics and dynamics governs the behavior of nanocrystals in solution. These dynamics are usually interpreted in terms of the theory developed by Derjaguin, Landau, Verwey, ...

For a car to accelerate there has to be friction between the tire and the surface of the road. The amount of friction generated depends on numerous factors, including the minute intermolecular forces ...

Proteins are made of amino acid chains, or polypeptides. Amino acids have a basic backbone made of an amino group and a carboxyl group, and differ in their side-chains. These polypeptide chains of ...

Intermolecular bonds are found between molecules. They are also known as Van der Waals forces, and there are several types to consider. London dispersion forces are the weakest type of intermolecular ...

Hydrogen, ammonia, methane and pure water are also simple molecules. All have strong covalent bonds between their atoms, but much weaker intermolecular forces between molecules. When one of these ...

Scientists have been asking that question of the limber little gecko for at least 75 years. These scaly climbers can scuttle nimbly across a polished glass ceiling. In a pinch, they can hang by one ...
