The dielectric permittivity, optical transmission spectrum and temperature dependence of resistance were investigated in single crystals of Bi 4 Ti 3 O 12 and BaBi 4 Ti 4 O 15 . It is found that the dielectric anomalies previously reported below the Curie temperature are due electron space charges of inhomogeneous dis…

The intensity of scattered light at angles between 30 degrees and 120 degrees has been measured during the heat gelation lag phase of rat tail tendon collagen. As previously reported, the intensity at a scattering angle of 90 degrees does not change during the lag phase of gelation, whereas during this period, the int…

The interrelationship between the various chloride ion containing compounds associated with the corrosion of iron in a marine environment is reviewed, and their role in corrosion promotion is evaluated as a basis for the selection of conservation techniques with a high probability of success.

Mesomorphic derivatives of 2-substituted 5-p-alkyl(alkoxy or cyano)phenylpyridines, 1,4-disubstituted piperidines, and ethyl 5-p-alkylphenylthiophene-2-carboxylates have been synthesised and their liquid crystal properties compared with those of analogous benzene and cyclohexane derivatives. Intermediates in the pyrid…
A large number of laterally fluorinated 4-n-alkyl- and -alkoxy-phenyl 4'-n-alkyl- and -alkoxy-benzoates and 4-n-alkylphenyl trans-4'-n-alkyl- and -alkoxy-cyclohexane-1-carboxylates were synthesised. In these compounds, the lateral fluoro-substituent was situated in either the phenol or the carboxylic acid moiety of th…
The optical properties of Kapton type H polyimide film, obtained from reflectance measurements, are presented for photon energies from 0.5 to 70 eV. Equations for the energy-loss function, with parameters fixed by the optical data, are employed to calculate mean free paths and stopping powers for low-energy electrons…
The optical transmission spectrum of a discontinuous metal-island film is strongly affected by extremely thin layers (<1 monolayer) of dye adsorbate. Experimentally observed splitting and broadening of the plasma resonance of silver films with adsorbed rhodamine B and nile blue dyes can be described by an effective-me…
Molecular absorption is shown to be substantially enhanced near rough metallic and dielectric surfaces. The conditions under which this may lead to enhanced photochemical processes are investigated.(AIP)

An approximation scheme is derived to calculate the velocity-autocorrelation function for the Lorentz model of overlapping hard discs and hard spheres. The theory describes a feedback between the particle-density correlations and the current relaxation rate, and is shown to give a percolation edge, a transition from t…
Electron spin resonance (ESR) and infrared absorption (IR) experiments have provided information about the role of aluminum in the radiation response of commercially available high-quality synthetic quartz. Samples obtained from two separate sources were investigated, and identical radiation responses were found for t…
Abstract The effect of saturated aliphatic fatty acids and a number of fluorinated polar organic compounds on the release of polyurethane foam from cold rolled steel has been investigated. Little release was observed with aliphatic acids of less than 10 carbons or with the organic compounds. Release behavior increased…
Immiscibility temperatures of Na 2 O‐B 2 O 3 ‐SiO glasses, with andwithout 1 mol% MoO 3 , additions, were determined and the effect of MoO 3 additions on the 65O°C immiscibility isotherms was established. In addition, immiscibility temperature and phase‐separation morphology of an Na 2 O‐B 2 O 3 ‐SiO 2 glass with prog…
