The major application of solders is for making electrical connections in the electrical and electronics industries.
Another major application of hydrogen is in the catalytic hydrogenation of organic compounds.
A major application of coordination compounds is their use as catalysts, which serve to alter the rate of chemical reactions.
Enantioselectivities exceeding 90 percent of a single enantiomer are commonplace in enantioselective hydrogenations, a major application of which is in the synthesis of enantiomerically pure drugs.
A major application of research in social interaction and group behaviour is in training in social skills, as in the T-groups, or sensitivity training, noted above.
