Low- and high-temperature x-ray diffraction investigations of titanium dihydride (TiH/sub 1.99/) and dideuteride (TiD/sub 1.98/) have indicated apparent 'second-order transformations' in both substances below a critical temperature of 310 deg K. The tetragonal low-temperature phases are distortions of the cubic fluori…

Abstract Les grandes différences dans le cours du dégagement électrolytique de l'hydrogène sur les différents métaux doivent provenir principalement de différences dans l'état de la liaison des atomes H chimisorbés, qui apparaissent comme produit intermédiaire dans ces réactions. On en déduit que le ralentissement des…

An attempt is made to analyze the factors which determine the operation of the bubble chamber. It is concluded that the majority of bubbles in conventional chambers are nucleated by moderately energetic free electrons produced by the incident particles in Coulomb encounters. Nuclei are displaced too infrequently by Co…
Abstract Sorption and diffusion of C 4 and C 5 hydrocarbons have been studied in thin films of ethyl cellulose in the temperature range 30 to 80°C. Only regions of low penetrant concentration were chosen in order to minimize hysteresis effects associated with slow relaxation of polymer chains. The data have been quant…
Silicon is electropolished in hydrofluoric acid solutions if a critical current density is exceeded. Below the critical c.d., silicon dissolution is largely divalent, and a thick solid layer forms. This film is unstable and reacts slowly with the electrolyte to form tetravalent silicon and hydrogen gas. In the electro…

SynopsisAll the important questions in counting phytoplankton are reviewed. The methods described refer primarily to fresh water but are applicable to marine phytoplankton as well. No attempt has been made to review the whole of the voluminous literature on counting technique or describe its development. The main aim…

THE FUNCTION OF THE SONISCOPE IN ITS VARIOUS APPLICATIONS TO THE STUDY OF MATERIALS IS DISCUSSED. THREE LABORATORY INVESTIGATIONS ARE REVIEWED. FIRST, THE SONISCOPE WAS USED TO MEASURE THE SETTING TIME OF CONCRETE. FOUR CEMENTS (ASTM TYPES I, II, III AND IV) WERE USED TO MAKE CONCRETES OF A RATHER STIFF CONSISTENCY. V…
A criterion is proposed for determining the onset of ferromagnetism in a material as its temperature is lowered from a region in which the linearity of its magnetic moment versus field isotherm gives an indication of paramagnetism. Within the limits of validity of a molecular field treatment, the Curie temperature is…
Abstract Measurements have been made of the variation with crystal orientation of the anomalous skin resistance of plane surfaces of pure copper at low temperatures and at a frequency of 22700 Mc/s. The resistance is related to the geometrical form of the Fermi surface, and a surface is determined which has the correc…
