Multi-Texture Mapping on Terrain by the Constraints Based on Random Noise
Constraints Height Randomnoise Texture Mapping Topography
2011/12/20
The terrain in the virtual realistic environment will determine the scene generation level of realism. It has been a hot topic in computer graphics. In this paper, the analysis of the current generati...
Swelling and Texture of Iron-Bearing Smectites Reduced by Bacteria
Bacteria Biological Reduction Organo-Clay Interactions Smectites Structural Iron Swelling Pressure Texture
2011/12/8
Abstract: Microbial reduction of clay mineral structural Fe(III) decreases the swelling of nontronite gels, most importantly at intermediate oxidation states (40 to 80 cmol Fe(II) kg−1 clay). Th...
A Technique for Maintaining Texture and Permanent Expansion of Smectite Interlayers for TEM Observations
Illite LR White resin R1 I/S Rectorite Smectite Transmission electron microscopy (TEM)
2011/12/1
Abstract: A process for treating smectite-bearing rock samples that utilizes LR White resin; allows TEM observation of expanded smectite interlayers and therefore preservation of original rock texture...
Morphology, Texture, and Microstructure of Halloysitic Soil Clays as Related to Weathering and Exchangeable Cation
Exchangeable cation Halloysite Interstratification Microstructure Smectite TEM
2011/12/31
This paper aims at characterizing the morphology, texture, and microstructure of three hydrated kaolin rich clays (f < 0.2 µm) from volcanic soils. These clays represent a weathering sequence in...
Effects of Iron Oxidation State on the Texture and Structural Order of Na-Nontronite Gels
Electron diffraction Ferric iron Ferrous iron High-resolution transmission electron microscopy Layer structure Nontronite
2011/12/31
Aqueous gels of unaltered (oxidized) and chemically reduced ferruginous smectite (SWa-1 from the Source Clays Repository of The Clay Minerals Society) were characterized by transmission electron micro...
Nitrogen surface areas and pore-size distribution curves of various chrysotiles have been measured using a continuous flow method. A model founded on a hexagonal close packing of fibers has been adjus...
