Redetermination of katayamalite, KLi3Ca7Ti2(SiO3)12(OH)2
The crystal structure of katayamalite, ideally KLi3Ca7Ti2(SiO3)12(OH)2 (potassium trilithium hepta-calcium dititanium dodeca-silicate di-hydroxide), was previously reported in triclinic symmetry (C-1), with isotropic displacement parameters for all atoms and without the H-atom position [Kato & Murakami (1985 ▶). Mineral. J. 12, 206-217]. The present study redetermines the katayamalite structure...
متن کاملThe crystal structure of katayamalite
The crystal structure of katayamalite has been determined by Patterson method and refined by the least-squares method using single crystal diffractometer data, giving R = 0.057 for 5785 reflections. Formula: (K,Na)Li.Ca,(Ti,Fe'+,Mn)2[Si60'8].(OH,F)2' Cell dimensions: a 9.721(2), b 16.923(3), c 19.942(3)A, a 91.43(10t, iJ 104.15(11t, 'Y 89.94(10t, space group Cl, Z = 4; or a 9.763(2), b 9.721(2)...
متن کاملIntroducing a New Experimental Islet Transplantation Model using Biomimetic Hydrogel and a Simple High Yield Islet Isolation Technique
Background: Islet transplantation could be an ideal alternative treatment to insulin therapy for type 1 diabetes Mellitus (T1DM). This clinical and experimental field requires a model that covers problems such as requiring a large number of functional and viable islets, the optimal transplantation site, and the prevention of islet dispersion. Hence, the methods of choice for isolation of functi...
متن کامل"Majorite" and "silicate perovskite" mineral compositions in xenoliths from Malaita.
Mineral Compositions in Xenoliths from Malaita The report by Collerson et al. (1) of transition zone and lower mantle phases in mantle-derived material from alnöite pipes on Malaita, Solomon Islands, is highly significant in view of the rarity of such natural assemblages. Malaita is part of the obducted southern margin of the Ontong Java Plateau, an area of overthickened oceanic crust (2–7) tha...
متن کاملMAGNETISM OF RANDOMLY CANTED Li-Ti FERRITE
FC-ZFC magnetisation, hysteresis, thermoremanence and neutron diffraction measurements were performed on Li1.125Feo.625Ti1.2504. The results are interpreted from domain and wall properties resulting of local canted state where the spin transverse component relaxes between preferential directions.
