Monoclinic Hydroxyapatite

Science, 1973
The existence of a monoclinic phase of hydroxyapatite, Ca 5 (PO 4 ) 3 OH, has been confirmed, by single-crystal structure analysis (weighted "reliability" factor = 3.9 percent on |F| 2 ). The structure has space group P 2

Monoclinic Thorium Silicate

Nature, 1950
THE name ‘huttonite’ is proposed for a newly recognized monoclinic mineral of the composition ThSiO4. It has been isolated in minute grains from beach sand of South Westland, New Zealand, by Prof. C. Osborne Hutton, of Stanford University. Its optical properties are: α= 1.898, β= 1.900, γ = 1.922; dispersion ρ > γ, moderate; 2V = 25° (measured); Y || b,

Crystal Structure of Monoclinic Hafnia and Comparison with Monoclinic Zirconia

Journal of the American Ceramic Society, 1970
The crystal structure of monoclinic HfO 2 was determined using Weissenberg techniques. Data were obtained from a needlelike single crystal which was grown from a lithium molybdate melt. The crystal was rotated about the α axis, and reflection data were obtained for nine levels.

The intermediate monoclinic phase of phosphatidylcholines

Biochimica et Biophysica Acta (BBA) - Biomembranes, 1977
Two pure phospholipids, dimyristoyl phosphatidylcholine and dipalmitoyl phosphatidylcholine, have been studied using freeze-fracture electron microscopy and the partitioning of the spin label, TEMPO. It is found that the characteristic band pattern, corresponding to monoclinic symmetry in multilamellar liposomes, is observed only in freeze-fracture ...

Superhard Monoclinic Polymorph of Carbon

Physical Review Letters, 2009
We report a novel phase of carbon possessing a monoclinic C2/m structure (8 atoms/cell) identified using an ab initio evolutionary structural search. This polymorph, which we call M-carbon, is related to the (2x1) reconstruction of the (111) surface of diamond and can also be viewed as a distorted (through sliding and buckling of the sheets) form of ...

Toughening by Monoclinic Zirconia

Journal of the American Ceramic Society, 1983
The toughening induced by monoclinic ZrO 2 in the absence of microcracking was investigated, using ZnO as the host material. Toughness levels K c in excess of the host toughness

A Reappraisal of the Natal Monocline

South African Geographical Journal, 1959
Abstract The Natal monocline is a Jurassic coastal flexure by which Karroo beds, disposed sub-horizontally throughout most of the province, are caused to bend down eastwards to below sea-level thereby creating the original coastline of Natal. Early and late Tertiary cyclic landsurfaces likewise rise inland from the coast to the monoclinal axis (over 2 ...

Hydroxyapatite: Hexagonal or Monoclinic?

Crystal Growth & Design, 2009
Bioapatite, the major constituent of mineralized tissues in mammalian bones and teeth, has been modeled to the hexagonal hydroxyapatite phase. Monoclinic hydroxyapatite, synthesized before only at very high temperature, is the thermodynamically most stable phase and is expected to exist also in hard tissues.

MONOCLINES OF THE COLORADO PLATEAU

Geological Society of America Bulletin, 1955
Powell should be given the credit for the idea advanced in 1929 by Busk that a monocline is a double bend consisting of the anticlinal and synclinal bends. In the Colorado Plateau monoclines have an aggregate length of nearly 2500 miles, and the greatest nearly uninterrupted monocline is about 300 miles long. Every gradation from gentle open monoclines
