Three-dimensional (3D) modelling of geological body is an important issue of 3D GIS and 3D Geosciences Modelling, and one of the key technologies of digital mine. GTP model and its components are introduced in this paper. According to the relations between chronolith and rock attribute comprehensively, the modelling region, system, series, group and rock characteristics(RC) are regard as the sc...

In this communication we present a study of the electronic structure of partially disordered bulk and (100) thin film of quaternary pseudo-Heusler alloy Co2Fe0.4Cr0.6Al in the L21 phase using the Augmented Space recursion (ASR) in a scalar-relativistic tight binding linear muffin-tin orbitals (TB-LMTO) basis. We study the orbital resolved magnetic moment contributions of the constituents of the...

in this paper, tin dioxide nanoparticles were synthesized by a fast and simple co-precipitation method. for sno2 preparation, we used ammonia as precipitation agent and bis (acetylacetone) ethylene diamineas as capping agent. by changing in sncl4, acacen mole-ratio different morphologies were obtained. this semiconductor nanostructure has photo-catalyst activities and can degrade organic dyes a...

A procedure whereby reflectance spectroscopy can be employed for the analysis of substances resQlved on thinlayer plates was developed with the use of metal cation mixtures that had been separated on cellulose plates. A rapid method was devised whereby fourteen cations were separated and identified ~~ by their reflectance spectra after chromogenesis with a mixture of dithizone and 8-hydroxyquin...

A surprising magnetic behavior of 3d transition-metal monolayers on the (100) tungsten surface has been reported recently [Ferriani et al., 2005]. The tendency to ferromagnetic (V, Cr, Mn) vs. antiferromagnetic (Fe, Co) order in these layers differs significantly from the situation on many other substrates, e.g. on W(110), Cu(100) or Pd(100). The aim of our work is to explore further the proper...
