Polymers in solutions : principles and applications of a direct renormalization method
The configurational properties of long polymers in solution can be conveniently studied by using a direct renormalization method, recently introduced by the author. This method is described here in detail and applied to the two parameter model. The indices γ, ν and ω are calculated directly to second order in ε = 4 -…
Heat capacity and other thermodynamic properties of linear macromolecules. II. Polyethylene
The heat capacity of polyethylene from 0 K to 600 K is reviewed using measurements on 46 samples reported in the literature. The crystallinity dependence is evaluated critically and a set of recommended data for completely crystalline and amorphous polyethylene is derived. Entropy, enthalpy, and Gibbs energy functions…
Effects of Radiation on Materials
Description Extensive information on current research results dealing with the effects of radiation on light-water-reactor pressure vessels, fast breeder reactor core materials, material for first-walls in fusion systems, and solid radioactive waste.
Secondary Electron Emission
When the surface of a solid is bombarded with charged particles of sufficient kinetic energy, emission of electrons by the solid may be observed. This phenomenon of secondary electron emission was discovered by Austin and Starke in 1902 in a study of the reflection of electrons by metals; they observed that under cert…
A solid silaethene: isolation and characterization
The first reported solid silaethene, m.p. 95 °C, stable at room temperature under argon, but highly reactive in air has been isolated and characterized by i.r., n.m.r. and mass spectrometry.
Fast Breeder Reactors
This book describes the major design features of fast breeder reactors and the methods used for their design and analysis. The foremost objective of this book is to fulfill the need for a textbook on Fast Breeder Reactor (FBR) technology at the graduate level or the advanced undergraduate level. It is assumed that the…
Synthesis and X-ray structural characterization of the centred icosahedral gold cluster compound [Aul3(PMe2Ph)10Cl2](PF6)3; the realization of a theoretical prediction
The gold(I) complexes AuCl(PR3)(PR3= PPh3, PMePh2, and PMe2Ph) react with Ti(η-C7H8)2 to form a variety of cationic gold cluster complexes; single-crystal X-ray analysis of one of these, [Au13-(PMe2Ph)10Cl2](PF6)3, has confirmed a centred icosahedral geometry for the cluster, in agreement with an earlier theoretical p…
Agglomerate and Particle Size Effects on Sintering Yttria‐Stabilized Zirconia
The initial‐, intermediate‐, and final‐stage sintering of fine crystallite yttria‐stabilized zirconia was studied. Experiments were conducted on powder lots of differing agglomerate size and one specially prepared agglomerate‐free powder. Initial‐stage sintering kinetics were compared with a sintering study on larger…
Water structure and changes in thermal stability of the system poly(ethylene oxide)–water
The phase behaviour of aqueous solutions of poly(ethylene oxide), PEO, is analysed by means of a structural model of the system and a simple statistical-mechanical model based thereupon. The intention is to elucidate the structural questions involved in the water–PEO coupling and to gain some insight in possible conse…
Fluorimetry study of N-(1-pyrenyl)iodoacetamide-labelled F-actin. Local structural change of actin protomer both on polymerization and on binding of heavy meromyosin.
A fluorescent reagent, N-(1-pyrenyl)iodoacetamide, was conjugated to rabbit skeletal muscle actin at the site of the most reactive sulfhydryl group, and fluorescence characteristics (excitation and emission spectra, quantum yields, lifetimes) of the conjugate were investigated. Associated with polymerization of labell…
Normal mode determination in crystals
Abstract The group theoretical methods by which the symmetries of normal modes in crystals may be determined are outlined, and a series of tables are presented to facilitate rapid determination of the selection rules for vibrational transitions. Emphasis is placed on the method of nuclear site group analysis in which…
The Formation, Structure, and Properties of the Extracomplexes of Porphyrins
The results of studies on the extracomplexes of metalloporphyrins namely the conditions of their formation, structure, spectroscopy, kinetics, and thermodynamics, are considered. The bibliography includes 245 references.
Optical detection of EPR of recombination centres in YAG
Crystals of yttrium aluminium garnet (YAG) emit a broad luminescent band peaking at 270 nm under X-irradiation at 4K. Exploitation of the magneto-optical properties of this emission makes possible measurement of EPR spectra of an excited state of the emitting centres. It is suggested that at least three different cent…
Conduction bipolarons in low-temperature crystalline WO3-x
Conduction electrons in the low-temperature phase of crystalline WO 3-x (x>or approximately=0.0001) are found to be paired diamagnetically, forming bipolarons due to joint lattice distortion. They can be dissociated with light in a broad band of wavelengths peaked at 1.1 eV, as monitored by the appearance of W 5+ E…
Core level binding energies for the elements Hf to Bi (Z=72-83)
The binding energies of all core levels in the N and O shells for the elements Hf to Bi have been measured by means of electron spectroscopy. The binding energies obtained are compared to previously reported values.
Kristallstruktur und Farbe bei Perylen‐3,4:9,10‐bis(dicarboximid)‐Pigmenten
Abstract Es wird versucht, extreme Farbtonunterschiede bei Perylen‐3,4:9,10‐bis(dicarboximid)‐Pigmenten durch ihre Kristallstruktur zu erklären. Dabei werden drei schwarze Pigmente mit fünf entsprechenden roten verglichen. Das N,N′ ‐Di(2,6‐xylyl)perylen‐3,4: 9,10‐bis(dicarboximid) wird gesondert diskutiert.
The structure of the high-temperature solid electrolyte lithium sulphate at 908K
The structure of the high-temperature, plastic form of lithium sulphate has been determined from neutron powder diffraction data collected at 908K. The structure is face-centred cubic, a=7.07 AA with the SO 4 2- ion situated at the origin and the oxygen atoms rotationally disordered about the sulphur atom. The Li + io…
The decomposition of hydrogen peroxide catalyzed with BF3 etherate; the use of this initiation system in the preparation of HO‐terminated telechelic polymers and copolymers of butadiene
Abstract Kinetics of the catalyzed decomposition of hydrogen peroxide in the presence of BF 3 etherate were investigated, and the basic kinetic parameters used in the discussion of the mechanism of this reaction were determined. The system hydrogen peroxide‐BF 3 etherate was used in the initiation of the radical polym…
