Hydrogen in polycrystalline diamond: An infrared analysis

B. Dischler、C. Wild、W. Müller-Sebert 等 4 位作者1993-04-01Physica B Condensed Matter

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

Kathleen A. Carrado、J. E. Forman、Robert E. Botto 等 4 位作者1993-04-01Chemistry of Materials

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

Stephen Hillier1993-04-01Clays and Clay Minerals

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

R. A. Young1993-04-01OpenAlex

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…
