Il n'existe qu'un petit nombre de catalyseurs capables d'effectuer dans des conditions optimales une réaction donnée. Le catalyseur réel adapté à un procédé particulier est le plus souvent un solide complexe. Il comporte une phase active qui, pour développer une surface maximale, est déposée sur un support, parfois à dose très faible s'il s'agit d'éléments coûteux comme les métaux précieux. Cependant, certains catalyseurs dits massiques sont uniquement constitués de phase(s) active(s) [...] [que l'on peut classer en trois grandes familles] : les métaux; les semi-conducteurs, oxydes, sulfures ou autres ions supportés; les oxydes isolants, acides ou basiques. 4, record 1, French, - catalyseur

Molecules are usually forms into aggregates called clusters by the intermolecular force, and their physicochemical behavior is sometimes different from that of bulks. Clusters are classified into the van der Waals cluster, covalent cluster, hydrogen bond cluster, metal cluster, ionic bond cluster, and so on. These types of cluster are expected to be applied to surface modification and so on. 2, record 2, English, - van%20der%20Waals%20cluster

An analytical technique analogous to x-ray diffraction in which an incident beam of neutrons is scattered by the atoms of a crystal. 2, record 4, English, - neutron%20diffraction
Record number: 4, Textual support number: 1 CONT
Because elements that are close to each other in the Periodic Table differ considerably in their neutron-scattering ability, neutron diffraction is capable of distinguishing between them. For example, carbon nitrogen, and oxygen atoms can be readily identified by neutron diffraction, where as they appear almost identical by the x-ray method. More accurate determination of the bond lengths of light atoms and distribution of molecular bonding electrons is also possible. Details of molecular structure that can only be inferred by other techniques can often be observed directly by neutron diffraction. Investigations using this method include hydrogen bonding, so-called metal cluster compounds(C. H. M relationships) and electronic charge distributions. 2, record 4, English, - neutron%20diffraction
