Successive substitutions in the pyrrole rings of tetraphenylporphyrin by up to four cyano-groups lead to large additive anodic shifts of the redox potentials. These shifts are large than those observed with other electron-withdrawing substituents. The stoicheiometry and stability of the complexes formed from metallote…

Abstract Cyclization in the chain polymerization of bis unsaturated monomers has been treated by cascade formalism based on primary chains for a kinetically controlled reaction. The primary chains consist of repeat units bearing an unreacted (pendent) double bond and units engaged in effective branchings (crosslinks),…

Polycrystalline Al 2 O 3 fabricated into plates or shapes by hot‐working techniques exhibits high in‐line transmittance from 0.4 to 5.5 μm. Examination of the product by an inverse pole figure technique demonstrated a strong {0001} texture normal to the pressing direction for both equiaxed and textured microstructures…

Autohesion is discussed emphasising in particular the influence of polymer chain structure on apparent rates of diffusion. The full range of autohesive levels which exists amongst rubbery polymers is rationalised by proposing a distinction between inter-chain free volume and “intra-chain” free volume, the latter being…

The phenomena of deep inelastic electron scattering on single nucleons, viewed as virtual photon absorption, are reexamined with the nonspeculative, phenomenological attitude of source theory. The use of a double spectral representation for forward scattering, and of experimental inputs from the low energy resonance r…

A study has been made of the use of optically active additives in twisted nematic devices to remove areas of reverse twist, the results obtained depending on the chirality of the additives and the director alignment on the two containing surfaces. Under certain conditions degeneracy of the field induced reorientation…

Abstract Colour changes of YAG crystals doped with rare earth ions and annealed in hydrogen, oxygen, vacuum or argon are described. The influence of UV irradiation is also given. Some crystals were further doped with Ca, Sr, Ba, or Cr, respectively. Yellow or brown colouring of the crystals is attributed to the O − ce…

This paper describes the principles of a method for the solution of electron optics problems which has led to significant design improvements in traveling wave tubes over the past few years. In contrast to Conventional procedures which solve Poisson's equation on square meshes, the space within the problem boundaries…

The autoxidation of 5-Methyl-5,6,7,8-tetrahydrofolic acid has been studied by kinetic methods and product analysis. The yields of the two major products, 5-methyl-5,6-dihydrofolic acid and 4a-hydroxy-5-methyl-4a,5,6,7-tetrahydrofolic acid, were determined under a variety of conditions. Attempts to observe or isolate p…

A galvanic cell study of the Ca + CaCl2 system is reported. By proper allowance for electronic conduction in the electrolyte phase, the thermodynamic properties have been determined. These data are in good agreement with a vapour pressure study and phase diagram determinations. A model is proposed based upon non-stoic…

The structure of the title compound has been established by three-dimensional X-ray crystal-structure analysis from diffractometer data. Crystals are monoclinic, space group P21/c, with a= 8·65(1), b= 17·64(1), c= 8·38(1)Å, β= 93·20(10)°, Z= 2. The structure was solved by the heavy-atom approach and molecular paramete…

A simple two-band theory of galvanomagnetic effects in graphite has been developed so as to involve not only the magnetic field intensity ( H ) but its azimuth (θ) with respect to the c-axis, which successfully accounts for the complicated behavior of transverse magnetoresistance (Δρ/ρ 0 ) in an iron-melt graphite pre…

Vitreous silicas containing up to 10% titania are of significant commercial importance because of their low thermal expansions. Instrumental techniques are being developed to determine the structure of the titanium groups in these glasses in order to relate their reduced thermal expansitivities with structural propert…

Simple electron-microscopy techniques are described which allow one to detect the presence of two enantiomorphous forms of a structure within an apparent single crystal. The first method consists of a characterization of the interface between the two enantiomorphs. In the second method advantage is taken of violations…
