SUMMARY: Irrespective of the nature of the growth-limiting substance, the potassium content of Aerobacter aerogenes (growing in a chemostat at a fixed dilution rate) increased progressively from about 1.3% to 4.2% of the bacterial dry weight with changes in culture NaCl concentration from 0 to 40 g./l. Similarly, the…

Methods are described for analysing the high-temperature thermodynamic properties of crystals into quasi-harmonic (qh) and explicit anharmonic (anh) contributions. The most useful functions to investigate are the entropy, the constant volume heat capacity and the Grüneisen parameter γ( T,V ) = β V /χ s C p . Δ S anh a…

Studies are described which involve the routes to the equiaxed fine structure needed for superplastic behaviour in two-phase Zn–Al alloys. These indicate that the development of a spinodal structure is not an essential step towards achieving a superplastic structure in this alloy. Some microstructural aspects and mech…

The small-angle scattering of a non-graphitizable carbon produced from polyacrylonitrile is studied. The evaluation of the scattering data has been based on recent developments in small-angle scattering theory. The results show the existence of a micropore system with diameters in the 10–30 Å range. The average pore d…

Spectral changes in iron(11) complexes caused by temperature changes have been examined. When the iron(11) ion is surrounded by six equivalent ligands (FeC12, FeBr2, FeI2, FeSiF6,6H2O) the band separation that arises from the splitting of the 5Eglevel decreases on cooling. The variation is proportional to the magnitud…
