The helium dimer is a van der Waals molecule with formula He 2 consisting of two helium atoms. [2] This chemical is the largest diatomic molecule—a molecule consisting of two atoms bonded together. The bond that holds this dimer together is so weak that it will break if the molecule rotates, or vibrates too much.
The first small molecule CID system was developed in 1993 and used FK1012, a derivative of the drug tacrolimus (FK506), to induce homo-dimerization of FKBP. [2] This system was used in vivo to induce binding between cell surface receptors which could not bind in the normal way because they lacked the transmembrane and extracellular domain.
Here, the resulting dimer has a stoichiometry different from the initial pair of monomers. Disaccharides need not be composed of the same monosaccharides to be considered dimers. An example is sucrose , a dimer of fructose and glucose, which follows the same reaction equation as presented above.

Atomic manipulation is the process of moving single atoms on a substrate using Scanning Tunneling Microscope (STM). The atomic manipulation is a surface science technique usually used to create artificial objects on the substrate made out of atoms and to study electronic behaviour of matter. These objects do not occur in nature and therefore ...
Lewis acid–base complexes between transition metal fragments and noble gases are among the weakest of bonds with substantial covalent character, with (CO) 5 W:Ar having a W–Ar bond dissociation energy of less than 3.0 kcal/mol. [20] Held together entirely by the van der Waals force, helium dimer, He 2, has the lowest measured bond ...
Electromanipulation is a micro-material analyzing method mostly used for manipulations of biological cells that uses properties of diverse electric fields.In nanotechnology, nanomaterials are so small that they can hardly be directly mechanically manipulated.
