    Notes: [Auszug] IN continuation of work carried out in this Laboratory on the electric and magnetic properties of thin metallic films1, we have now investigated the resistivity of nickel films (20 mµ–700 mµ) between −236°C. and 400°C. The films are deposited on thin glass sheets by using ...

    Notes: [Auszug] USING an acoustical interferometer (frequency of the quartz crystal, 539.6 kc./s.), we have measured the velocity of sound in various liquids (carbon tetrachloride, benzene, ethyl ether and carbon disulphide) between 80° C. and the melting point of these liquids (see Fig. 1). In order to check ...

    Notes: [Auszug] IN an earlier communication1, we reported on measurements on the electrical resistance of thin nickel films. We found at that time that for a thickness greater than 40 mµ the films possess a positive temperature coefficient, whereas for smaller thicknesses the temperature ...

    Notes: [Auszug] IN catalytic phenomena the ferromagnetic metals (iron, cobalt, nickel) possess a special interest. On the other hand, it is also known that adsorption phenomena are closely connected with catalysis. In continuation of systematic work carried out during recent years in this laboratory on ...

    Notes: [Auszug] IN continuation of our previous measurements on the velocity of ultrasonics (frequency 523 kc.) in condensed gases at low temperatures1, we have now measured the velocity of sound in liquid hydrogen under its saturated pressure as a function of temperature between 21° and 14° K. ...
