By reviewing Lanzhou urban green system planning development since 1949, this paper analyses the guiding principles, the dominant function and layout structure of urban green system planning construct...
According to the comprehensive detailed analysis of data such as, drilling core, logging and outcrop section, four kinds of sedimentary facies, namely, proluvial fan, braided river, shallow water brai...
As we know, agricultural waste like rice husk & straw etc., are produced a lot from the rice paddy special caution is needed in order to prevent the resulting serious environment pollution. Due to lac...
The relationship between surface properties and water vapor absorption performance was studied according to crystal structure and surface free energy of purified palygorskite. The results show that th...
Based on the dispersion characters of organic modified attapulgite (OAT) short fibers in nature rubber (NR) matrix, this paper analyzed the effects, in terms of addition amount of OAT, processing tech...

Abstract: A new model for the interpretation of dioctahedral mica infrared (IR) spectra in the OH stretching vibration region is proposed. It is based on the analysis of the main factors responsible f...
Transmission electron microscopic (TEM) examination has shown that multi-domainic crystals of synthetic goethite consist of almost parallel intergrowths, each of which is slightly misoriented with res...
The orientation of the OH-vectors in hydroxyl groups of micas of different compositions, polytype modifications, and symmetry were calculated by the method of minimization of electrostatic energy. The...
Kaolinite is synthesized in approximately the same time in three temperature ranges: (1) from 200–250° to 350–400° (hydrothermal processes); (2) from 120 to 175° (semihydrothermal ones); (3) at ordina...
The adsorption of Cu2+ on kaolinite was studied at different ionic strengths following various treatments of the mineral surface in order to evaluate the conditions influencing adsorption. The data in...
Abstract: Major factors affecting the selected area electron diffraction (SAD) patterns of micas are: lattice properties of the crystal, specimen thickness, orientation of the crystal, properties of t...
Dodecylammonium chloride (DAC) is used as a reagent to displace potassium from a wide range of mica minerals. Displacement is rapid and essentially complete for trioctahedral micas even in dilute solu...
Deviations in the symmetry of mica single layers from the ideal arrangement with all atoms in hexagonal arrays are caused by the structural factors such as compositional variation (substitutions), ord...
Clay mineral data have been obtained on 348 soil profiles representing 117 different soil series from 28 of Pennsylvania's 67 counties. The surface rock from which the soils were formed ranged from Pr...
