A linear relation is established between the cosine of the contact angle and the temperature of a liquid metal sessile drop resting on a ceramic substrate. This relation is demonstrated for many liquid metal/ceramic systems. The work of adhesion and the effects of surface roughness, porosity, chemical reactions, and s…

The contributions of inelastic and elastic phonon scattering by neutral donors to the low-temperature thermal resistance of Ge are calculated in detail. It is shown that the inelastic and elastic scattering mechanisms make almost the same contribution to the thermal resistance in Sb-doped Ge. The sum of the both contr…
Abstract The variations in flow stress of FeCo : 2 at% V as a function of test or quench temperature exhibit a maximum near the critical temperature for ordering, T c . Transmission microscope study of thin foils reveals the existence of paired dislocations not only at temperatures below T c but also at temperatures…
The influence of a variety of water-insoluble monomolecular films on the evaporation rate of 50 to 500 μ diameter water drops was determined at 25C and 50% relative humidity. The results indicate that only linear polar molecules capable of close packing can form monomolecular films which inhibit the gas transport of w…

Antiferromagnetism in hcp Fe-Mn alloys (17.8, 25.9 and 28.6 at %Mn) was investigated by means of Mössbauer effect and neutron diffraction measurements. Néel temperatures and internal magnetic fields at 0°K were determined to be 230°K and 16 kG, respectively, over the composition range of the measured alloys. Consequen…
Twist boundaries have been observed on {001} surfaces between crystals of MgO and CdO smoke. Measurements of the angles of twist across several hundred of these boundaries have revealed preferences for boundaries at 16.5°, 22.6°, and 37.3° in MgO and 22.8°, 28.5°, and 37.1° in CdO. These angles agree with those predic…

Abstract Initial velocity kinetic studies of adenosine diphosphoglucose pyrophosphorylase from Rhodospirillum rubrum yield intersecting reciprocal plots indicating that the kinetic mechanism of this enzyme is sequential. ATP-pyrophosphate-32P isotope exchange at equilibrium studies indicate that the kinetic mechanism…
The current model of amorphous semiconductors is applied to give a description of the electrical behaviour of liquids which show a gradual transition from a semiconducting to a metallic behaviour as some parameter such as temperature or volume is changed. These include mercury at high temperatures, Te-Se alloys and ch…
An improvement is described in the automatic procedure for solving crystal structures incorporated in the computer program LSAM . The development of signs from an initial set containing symbols is carried only as far as is necessary to establish strong relationships between the symbols. The information so gained is us…
Abstract Mixing and processing methods used in the rubber industry have been designed to use the only form of raw rubber hitherto available—that of a high molecular weight solid. But rubber in high molecular weight form is essential only in the finished product; in principle, similar final properties could be obtained…
Il est bien connu que la présence de manganèse dans un alliage fer-azote conduit à une déformation marquée du pic de Snoek de l'azote. Cette modification du pic a deux conséquences importantes : - dans le dosage de l'azote interstitiel par la méthode du frottement intérieur, il est nécessaire de tenir compte de la mod…

Abstract The infra‐red spectrum of polyvinyl acetate has been studied from 4000 to 150 cm‐1 and a detailed assignment made. To assist with the assignments the partially deuterated polymer, poly‐α, α, β‐trideuterovinyl acetate, and a branched‐chain acetate have been synthesised and their spectra examined.
Abstract From the differential thermal and thermogravimetric analyses of potassium oxalate together with the X-ray diffraction studies, three crystallographic modifications of the anhydrous salt were found. When potassium oxalate monohydrate crystals were dehydrated at, e.g., 140°C, phase II, which is stable below 381…
Abstract The literature on polymer morphology contains many studies of structural and orientation changes occurring upon uniaxial stretching of films and fibers, but it has only an occasional reference to such studies on biaxially stretched film. This paper presents data on a structural change due to simultaneous biax…
