Clay dikes, hydraulic caps and liners for hazardous containment systems, waste lagoons, cores in earth dams and other environmental isolation tasks are examples of structures built with compacted fine grained soils [1-3].
The large specific surface of montmorillonite (the primary clay mineral in bentonite) combined with its large net negative charge and an ability for interlayer swelling resulted in adsorption of a large number of hydrated cations as well as adsorption of water molecules, and interlayer separation during hydration [8, 11; 23].
These results are similar to those reported by a number of researchers (for example 11, 20, 26) for other soil - bentonite mixtures.

The finer grain size and greater liquid viscosity bring about the greater difficulty of concentrating and the higher cost.
Ceramic membrane is asymmetric membrane made of a ceramic material, and multi-channel tubular shape, a large number of pores distributed on the wall, the particles in the liquid under pressure which greater or similar with the pore size of the membrane will be retained, the others less than the membrane pore size will through the membrane, then achieve the purposes: particle separation, enrichment and concentration [2].
Membrane Cleaning After a period of operation, a large number of fine particles will be deposited in the membrane surface and inside, which can result significant reduce in membrane flux, so improving the life of the ceramic membrane through membrane cleaning is essential.

Increase the number of checking if there is a doubt that the amount of coal has an exception.
Its sample collector has a working pattern of: 6 rotary stations; sample grain size ≤ 6mm.The sample tank capacity is 16L / piece; the number of sample cans is 6.

It can be seen in 3D images that the thin film has a hill-valley-like morphology made of small grains.
The diagram shows that the surfactant and the number of layers have affect pores and particle size.
It is obvious that the thickness increases with the number of dippings: the thickness of one-layer coatings is from 0.09 to 0.11 μm, but that of six-layer coatings is from 0.12 to 0.15 μm.

The selection criteria for powder or filament-based raw materials are manufacturability, shelf life, stability (reactivity) and ability to make maximum number of components with minimum number of stock materials.
Grain size becomes comparable to feature size, diffusion distances are shorter, material flow occurs in confined spaces and material becomes sensitive to inhomogeneities and flaws.

Introduction A number of biocompatible materials are used nowadays for implant production: titanium, stainless steel, porcelain, bioceramics, alumina alloys and a number of polymers.
After 1h anodization the larger part of the sample’s surface is covered with nano-dots or nano-rods depending on the orientation of particular grains (Fig.2a).

The microstructure, such as the thickness and the scattering length densities of TiN layer and AlN layer, number of periods, the roughness of surface and interface, were obtained from fitting the experimental data.

Inside the porous ceramic tube, as the fluid flow through porous media, the gas flow in porous media can be divided into Darcy flow and non-Darcy flow under the Rek (Reynolds number) based on the permeability.
