sono-
(ˈsəʊnəʊ)
comb. form of L. sonus sound: sonoˈchemistry, (the study of) the chemical action of sound waves; so sonoˈchemical a., of or pertaining to sonochemistry; ˌsonolumiˈnescence Chem., luminescence excited in a substance by the passage of sound waves through it; hence ˌsonolumiˈnescent a.; soˈnolysis Chem. [-lysis 1], the decomposition by ultrasound of a liquid, esp. water, as a result of the high temperatures generated within the cavities formed; also, the secondary reactions between the unrecombined decomposition products and the liquid itself or compounds dissolved in it; hence sonoˈlytic a.; sonoˈlytically adv.; (as a back-formation) ˈsonolyse v. trans., to subject to sonolysis; ˈsonolysed ppl. a.
| 1953 Jrnl. Acoustical Soc. Amer. XXV. 655/1 In view of the frequent attributing of sonochemical reactions to the concomitant heating effect, it is curious that higher temperatures give smaller yields. 1966 New Scientist 12 May 367/1 (caption) It now seems that a substantial part of the ‘fixed’ nitrogen available to marine plants and animals is due to sonochemical processes in waves. |
| 1953 A. Weissler in Jrnl. Acoustical Soc. Amer. XXV. 651 (heading) Sonochemistry: the production of chemical changes with sound waves. 1958 New Scientist 25 Sept. 926/3 These conditions give rise to many remarkable effects which are now being studied such as sonoluminescence, ultrasonic cleaning and sonochemistry. 1966 Ibid. 12 May 367/1 It might well be said that an understanding of sonochemistry is the key to the understanding of numerous chemical changes which take place around us in everyday life. |
| 1939 Jrnl. Amer. Chem. Soc. LXI. 2392/1 The luminescence which appears when sound waves pass through liquids has been called acoustic or sonic luminescence, for short, sonoluminescence. 1958 Sonoluminescence [see sonochemistry above]. 1976 Jrnl. Acoustical Soc. Amer. LX. 103/2 The sonoluminescence from a gas dissolved in water is inversely proportional to the thermal conductivity of the gas. |
| 1974 Ultrasonics XII. 25/1 Chemical and sonoluminescent effects occur in gaseous (pseudo) cavitation but never in vaporous cavitation. |
| 1964 Jrnl. Chem. Physics XL. 608/2 Water and dilute (0·1M) sodium formate solutions of different isotopic composition were subjected to sonolysis under argon... Hydrogen peroxide was produced. 1976 Canad. Jrnl. Chem. LIV. 1114/1 In aqueous solution..the lifetime of chemically active radicals produced by sonolysis is larger than the lifetime of the cavitation bubble. |
| 1964 Jrnl. Chem. Physics XL. 608/2 In analogy to radiation chemistry of aqueous solutions, ‘molecular’ and atomic hydrogen are apparently produced under sonolytic conditions. 1966 New Scientist 12 May 367/2 Sonolytically induced polymerization may..compete with chemically induced processes. 1976 Canad. Jrnl. Chem. LIV. 1118/2 The mechanism whereby H2O2 is produced sonolytically has been the subject of some controversy. |
| 1964 Jrnl. Chem. Physics XL. 609/1 DCO2NaO·1M, 98%D (pH = 5·5), was sonolyzed in H2O. 1964 Jrnl. Physical Chem. LXVIII. 1460/1 The analogy between the behaviour of radiolyzed and sonolyzed aqueous solutions has been pointed out in several studies. 1966 New Scientist 12 May 366/1 We may thus envisage a sonolysed system as a heterogenous process wherein small centres of very high temperature exist in transient gas bubbles dispersed in a liquid medium. |
