mechanochemistry|ˌmɛkənəʊˈkɛmɪstrɪ|
[f. prec. + chemistry.]
The study or phenomenon of mechanochemical processes.
1928P. M. Travis Mechanochemistry 3 This new science of mechanical dispersion, involving the principles of physical chemistry, I am calling ‘Mechanochemistry’, because it involves dispersion or deflocculation by mechanical means rather than by chemical. 1951Jrnl. Polymer Sci. VII. 407 A simplified model which discloses the principles of the mechanochemistry of polyelectrolytes will be shown here. 1961New Scientist 2 Mar. 548/3 In the USSR..the field of investigation has been aptly named ‘mechanochemistry’, in line with ‘electrochemistry’ and ‘photochemistry’. 1972Science 3 Nov. 460/2 A complete understanding of the sliding filament model for generating flagellar bending waves must include an understanding of the mechanochemistry of the active sites at the molecular level.
Hence ˌmechanoˈchemical a., pertaining to both mechanics and chemistry; spec. able to convert chemical energy directly into mechanical energy; ˌmechanoˈchemically adv.
1949W. Garner Textile Laboratory Manual i. 14 (heading) Mechano-chemical methods for single fibres. 1949A. Katchalsky in Experientia V. 320/1 In the phenomena discussed here the chemical ionization energy is transformed directly into mechanical energy. We may therefore regard them as the first synthetic examples of mechanochemical systems. 1961New Scientist 2 Mar. 549/2 The action of an internal combustion engine causes substantial changes in lubricating oil viscosity due to mechanochemical breakdown of the polymer being sheared between the narrow clearances. Ibid. 550/3 Mechanochemically initiated polymerization has been found to occur with a large variety of polymerizable substances using substrates other than rubber. 1964Oceanogr. & Marine Biol. II. 198 Takata suggested that in Acetabularia there may be an ATP sensitive protein that forms a mechanochemical system controlling protoplasmic streaming. 1972Science 3 Nov. 460/2 The basic mechanochemical process by which energy from ATP dephosphorylation is used to produce mechanochemical work may be very similar to the active sliding process. 1974Nature 31 May 475/2 Exergonic band cleavage would therefore occur in the mechanochemically coupled step. |
