Hydrogen in polycrystalline diamond: An infrared analysis
Abstract Hydrogen in polycrystalline diamond (PCD) films has been analysed by infrared spectroscopy. A series of differently prepared PCD films exhibiting considerable differences in the shape of the C-H stretch absorption band has been studied. The spectra are consistently explained by a superposition of lines from s…
Incorporation of phthalocyanines by cationic and anionic clays via ion exchange and direct synthesis
Phthalocyanines (Pc) and metallophthalocyanines were incorporated into the galleries of anionic and cationic clays via ion exchange and in situ crystallization of the synthetic clay layers. Intercalation compounds between the layered magnesium silicate clay hectorite and cationic phthalocyanines were directly prepared…
Origin, Diagenesis, and Mineralogy of Chlorite Minerals in Devonian Lacustrine Mudrocks, Orcadian Basin, Scotland
Abstract Chlorite and corrensite are common clay minerals in lacustrine mudrocks from the Devonian Orcadian Basin, Scotland. The relationship of their occurrence to vitrinite reflectance data demonstrate that they are authigenic minerals, formed during burial diagenesis/metamorphism at temperatures of ≥120°C. Whole ro…
Introduction to the Rietveld method
Abstract In Chapter 2, Dr Rietveld has provided an account of the inception and early development of his method and of the growth of its acceptance from being initially ignored to the very widespread and vigorous use in many fields that it now enjoys. In this chapter, we provide a general introductory account of what…
Modelling X-ray or neutron scattering spectra of lyotropic lamellar phases : interplay between form and structure factors
The lamellar phase of two binary systems, AOT/water and DDAB/water, is studied by X-ray or neutron scattering techniques, along dilution lines. We observe on both systems a large wave vector diffuse scattering with the following features : i) its shape is independent of dilution ; ii) its intensity scales linearly wit…
Enzymatic polyesterification in organic media. Enzyme‐catalyzed synthesis of linear polyesters. I. Condensation polymerization of linear hydroxyesters. II. Ring‐opening polymerization of ϵ‐caprolactone
Abstract With the object to synthesize polyesters by enzymatic catalysis in organic media, two directions have been investigated: (1) the condensation polymerization of linear ω‐hydroxyesters and (2) the ring‐opening polymerization of lactones. The commercially‐available crude porcine pancreatic lipase (PPL), suspende…
Nature of Alumina in Phosphate Glass: I, Properties of Sodium Aluminophosphate Glass
Glasses along four compositional tie lines, I: xAl(PO 3 ) 3 ’(1 – x)NaPO 3 , II: xAlPO 4 ′(1 – x)NaPO 3 , III: xAl 2 O 3 ′(1 – x)NaPO 3 , and IV: xNaAlO 2 ,(1 – x)NaPO 3 , have been prepared and a number of their properties evaluated. In general, Al 2 O 3 additions increase the glass transition temperature, decrease t…
