Advances in Inorganic Fluorine Chemistry Yoshiaki Matsuo, in Journal of Fluorine Chemistry, 2007 Fig. 4 shows the X-ray diffraction patterns of magadiite during silylation of it [19]. The interlayer spacing of sodium–magadiite was 1.56 nm and it increased to 2.81 nm after exchange reaction by...
The structure of amableite-(Ce) has a unit cell with the following parameters:a= 14.1340(2) ,c= 30.378(1) , andV= 5255.6(3) 3. In this paper, we propose a model for the distribution of cations within the amableite-(Ce) crystal structure based on a low-symmetryP3 space group. We...
leverettite (IMA 2013-011), ideally Cu3CoCl2(OH)(6), was found at the Torrecillas mine, Salar Grande, Iquique Province, Chile, where it occurs as a supergene alteration phase in association with akaganeite, anhydrite, chalcophanite, goethite, halite, manganite, pyrite, quartz and todorokite....
Evaluation of a single-tube real-time PCR for detection and identification of 11 dermatophyte species in clinical material We developed a dermatophyte-specific single-tube real-time PCR assay based on internal transcribed sequences. This assay allows the rapid detection and ide... AMC Bergmans,...
Accessory minerals in Santa Catharina are comprised of phosphides related to the schreibersite-nickelphosphide series, Fe3P–Ni3P39,40, sarcopside-like iron phosphate, Fe3(PO4)2, and magnetite39,41. Troilite nodules up to a few centimeters across are very common41. Troilite, FeS, is partia...
The presence of drugs in aquatic environments has been considered a global challenge and several remediation technologies have been proposed, including ads
This paper records the garnierite in Wadi Dubur Neoproterozoic serpentinites from the Central Eastern Desert of Egypt. Garnierite (Ni-Mg hydrous silicates) occurs in two types (Type I and Type II) of infillings in the weathered serpentinite that was displaced sinisterly by NNW-SSE trending stri...
The structural data and TEM analysis clearlyshow that the crystal chemistry of the extraframework cations, Mg in particular, is a majorfactor controlling whether erionite or offretite crystallizes, the Si-Al distribution in theframework, and the possible stacking intergrowths of the two minerals....
