Growth conditions, structure, and superconductivity of pure and metal-doped FeTe1-xSex single crystals Superconducting single crystals of pure FeTeSeand FeTeSedoped with Co, Ni, Cu, Mn, Zn, Mo, Cd, In, Pb, Hg, V, Ga, Mg, Al, Ti, Cr, Sr or Nd into Fe ion site... M Berkowski,...
Since normally HAP crystals grow along thec-axis, it has been assumed that enamel crystals also follow this growth pattern, yet PIC maps show clear evidence of a much greater angle spread compared to bright field TEM of enamel rods. The consensus model assumed co-orientation of long axis and...
Positive effects of the residual templates within the MCM-41 mesoporous silica channels in the metal-catalyzed reactions As-synthesized Pd/MCM-41 and Au/MCM-41 including the residual SDA organic templates, cetyltrimethylammonium bromide (CTABr), within the mesoporous channels...

Combining centuries-old Thai craftsmanship with modern design solutions, the project reflects the ethos of Chiangmai Life Architects, a firm devoted to elevating natural materials to their highest potential. In this article, we will explore some of the contemporary structural solutions applied to this...
By 17O isotopic labelling of the zeolite framework, in conjunction with advanced EPR methodologies and DFT modelling, we determine the local structure of single site CuII species, we quantify the covalency of the metal-framework bond and we assess how this scenario is modified by the presence ...
A method for forming germano-silicide contacts atop a Ge-containing layer that is more resistant to etching than are conventional silicide contacts that are formed from a pure metal is provided. The method of the present invention includes first providing a structure which comprises a plurality of...
Thereby, it is demonstrated that such anomalies as those present in the observed structure factors for the Ga liquids at high temperatures are due primarily to the effect of the occurrence of particular clusters (or local-ordering units) on the states of pure Ga liquid.关键词:...
The two alkylidyne fragments lie on the same side of the M–M′–M axis such that the compounds have approximate C2 molecular symmetry.55,174 The disposition of the edge-bridging alkylidyne groups is such that the two dimetallacyclopropene rings which share a common vertex (M′) are ...
