The effects of prior deformation, grain size, and grain-boundary and twin-boundary energy on the frequency of occurrence of annealing twins has been investigated. Deformed materials generally exhibit peaks in their twin frequency vs. grain size curves while undeformed materials do not. In the absence of prior deformat…
Accurate measurement of the depolarisation ratios showed that maximum depolarisation (6//7) is observed only for the out-of-plane bending vibration. The (band area) depolarisation ratio for the CD in-plane bending band of DCO2–, 0·80, is slightly less, and that of the CH in-plane bending band of HCO2–, 0·64, considera…
The complexes present in freshly-prepared solutions containing cobalt(II) and cyanide ions have been investigated. The main complex is identified as the hexaco-ordinate [Co(CN)5H2O]3– by comparison of its spectrum with those of the analogous isocyanide complexes. No evidence was found for the hexacyanide [Co(CN)6]4– u…

Density (and some viscosity) data are presented for binary sodium borate melts containing as much as 60 mole % Na 2 O and for ternary sodium silicoborate melts with B/Si <2.0 between 1000°C and 1300°C. The high‐temperature partial molar volume analysis of the binary sodium borate melts reveals about 50% BO 4 tetrah…
Abstract Two high purity Al foils of thickness 40 μm and 5.6 μm are simultaneously irradiated. The initial resistivity increments per unit defect concentration for the foils differ by a factor of two due to the size effect. Sondheimer's theory is in good agreement with the experimental data. The calculations are prese…

Abstract Deformation processes in polymers are reviewed within the framework of rubber elasticity theory. The effect of hindered rotation on imposed and spontaneous length changes of polymeric fibers is discussed, leading to a new definition of crystallinity as a localized region of hindered rotation. This concept, to…
A hard-sphere model analogue of undirectional crystal growth has been devised and used to measure quantitatively the rates of growth normal to (111) and (100) planes in a face-centred cubic crystal structure. It has been found that 〈111〉 growth is much faster than 〈100〉 growth, and the result is interpreted in terms o…
Methods have been developed for growing thin polycrystalline films, and oriented polycrystalline films. Experiments with the thin films allow measurement of the absorption spectra of the N-salicylideneanilines well into the ultraviolet, and thus permit comparison of the effects of temperature change on the “thermochro…
Abstract Calculations of characteristic energy losses of electrons in thin dielectric foils are given for a) electrons with inclined incidence to the foil, b) electrons travelling parallel to the foil surface. Retardation is taken into account for case b) in the limit of very thick foils. For the special case in which…
The kinetics of the formation of zinc ferrite from zinc oxide and iron(III) oxide powders have been studied. Below about 1000°C Jander's equation is obeyed. Vaporization of the more mobile reactant (ZnO) occurs to form a coating on the particles of the other reactant with subsequent diffusion into it. An activation fr…
The isolation of complexes of stoicheiometry [Fe2B4O]X2Y2·xH2O (where B = 1,10-phenanthroline, X = Y = Cl, ClO4, NO3, or ½SO4, or X = Cl, Y = ClO4, or B = bipyridyl, X = Cl, Y = ClO4) is reported. For the chloride complex co-ordination of chlorine to iron appears to occur. The magnetic properties of the complexes over…
Abstract This study delineates the complex morphological‐deformation processes that occur during the spinning, fabrication, and testing of a series of drawn yarns as an integrated picture of mass movement on all morphological levels. The study involved the use of nine different experimental techniques, including small…

Passive films of γ ‐ Al 2 O 3 formed on aluminum by chromate solutions exhibit lower ionic resistance and higher electronic resistance than amorphous thermal films of the same thickness. The low ionic resistance is attributed to the formation of some crystalline γ ‐ Al 2 O 3 of very low ionic resistance at the oxide s…
Abstract A comparison is made of the properties of magnesium oxides prepared from basic magnesium carbonates and Indian and Greek rock magnesites. the density increased with burning temperature and the reactivity decreased. the effect of this on the properties of oxychloride cements is shown. Iodine number is shown to…
