1917 Nature 27 Dec. 337/1 The research provides an explanation of the well-known readiness with which materials change their tribo-electric character.

1967 W. R. Harper Contact & Frictional Electrification v. 77 The notorious difficulty of performing triboelectric experiments in damp weather proclaims the importance of adsorbed water.

1972 Sci. Amer. Mar. 54/3 Yarns, plastic films, paper and kindred materials moving at high speeds inevitably lead to triboelectric troubles.

1967 W. R. Harper Contact & Frictional Electrification v. 7 Glass cleaned with alkalis became triboelectrically ⊕ve with respect to metals.

1917 Nature 100 336/2 Tribo-electricity—that is, the subject which deals with the production of charges by rubbing together unlike materials.

1979 Adv. Colloid & Interface Sci. XI. 64 The roles of tribo-electricity in everyday life and in industry are numerous both as a nuisance and hazard and as a phenomenon to be exploited.

1938 G. P. Harnwell Princ. Electr. & Electromagn. i. 1 The production of electrification by the frictional process of rubbing is known as triboelectrification.

1967 W. R. Harper Contact & Frictional Electrification v. 85 The loosely bound ions are available to diffuse to another surface brought into contact with the one under consideration, and might be important..for triboelectrification.

1967 Brit. Jrnl. Appl. Physics 18 641 If a solid body such as a stirrer rod is rubbed against the inner wall of a vessel containing either a supersaturated solution of a salt or a supercooled liquid, the nucleation of crystals is likely to occur at the point of contact. This phenomenon is known as tribonucleation (‘nucleation by rubbing’).

1974 Nature 20 Dec. 696/1 One mechanism for the production of micronuclei in man, tribonucleation, has been suggested by Ikels.

1977 Jrnl. Catalysis 50 542/1 The catalyst produced by the tribophysical procedure is more active longer than the conventional one.

1950 Engineering 17 Mar. 303/3 The new Division of Tribophysics has developed from a section which, during the war, evolved some interesting theories regarding the fundamental nature of friction and lubrication.

1976 Sci. Amer. Apr. 30/2 Sanders, who is chief research scientist in the Tribophysics Division, heads a group that is engaged in studying the reactivity of metallic surfaces, relying mainly on electron microscopy.

1936 G. G. Simpson in Dental Cosmos LXXVIII. 797/1 At this stage the upper molar is implanted by two external and one internal root, the latter generally largest, and the lower molars are implanted by two sub-equal roots, one beneath the trigonid and one beneath the talonid... In order to have a single word..by which this type of molar dentition can be unequivocably..designated, I propose to call it ‘tribosphenic’.

1975 Nature 31 July 402/1 Therian mammals with tribosphenic molars were probably in existence at the beginning of the Cretaceous.

1975 Nature 31 July 402/1 Tribosphenic molars have an additional cusp on the upper molars (protocone) which fits into a basin (talonid) on the matching lower molar.

1930 Nyswander & Cohn in Physical Rev. 36 1257 The term tribothermoluminescence has been given to the phenomenon under consideration which involves the process of grinding followed by application of heat.

1971 Nature 23 July 257/2 Thermoluminescence (TL) of fossil bones and of various kinds of recent biological material has been reported by Jasińska and Niewiadomski, who suggest that such materials could be used for dating purposes, but draw attention to difficulties which arise due to tribothermoluminescence (TTL, which is thermoluminescence derived from the mechanical energy of grinding).
