So nanoscale materials and devices will play a major role in intelligent communication system.
Such materials and devices would certainly leverage the future direction of research in wireless communication systems.
The materials used in such devices should be robust, easy to use and easily deployable [3].
Nanometer-length scale materials play a vital role in the manufacturing and controlling of novel and innovative devices.

Experiment section Sample prepareation.A sample of approximately 3 to 4 grams was required.For materials of different specific gracity,this weight will need to be adjusted to fill the die cavity.If from sheet,the sample needs to be 34mm diameter and 4mm thick.However,samples can also be prepared from pellets or powders.
This method applies to materials containing greater than 20 % fines.In such cases,the relationship between stiffness and dry density or dry unit weight is sensitive to the water content.
V=Poisson's ratio E=Young's modulus,Mpa(kpsi),and G=Shear modulus,Mpa(kpsi) The stiffness and modulus of materials will change with moisture content and can possibly result in hydro-compaction collapse, loss of bearing capacity or loss of effective shear strength.Results obtained from this method are applicable to the evaluation of granular cohesionless materials.

This paper describes the available features of the fuzzy ball drilling fluid including efficient plugging, good carrying and suspension, formation damage control, compatible weighted by any weighted materials without auxiliary equipment.
About 40t cotton shells and lost circulation materials were used.
However, the application above prove that the fuzzy ball drilling fluids have good properties and can effectively increase ROP and save drilling fluid additives and lost circulation materials.
Also, it can effectively balance the high pressure of reservoir by making use of inert weighting materials to improve its density

Experiment Experimental materials and equipments The re-concentration mineral powders of RE dressing tailings in Bayan-Obo mine( Hereinafter referred to as re-concentration minerals) and semi-coke powders were used as experimental materials, in which the particle sizes of re-concentration minerals were ground to smaller than 150 mesh and the particle sizes of Semi-coke powders ranged from 1mm to 5mm.
The materials were taken out, and the sponge iron in materials was weighed.
(2) In direct reduction process of re-concentration mineral powders, fluorine compounds evaporated from the materials, meanwhile, potassium compounds evaporated or were reduced obviously.

Preparation of Humidity Control Ceramics from Selectively Leached Kaolin Shangfeng Du, Yunfa Chen and Yun Liang Multiphase Reaction Laboratory, Institute of Process Engineering, Chinese Academy of Science, Beijing 100080, China Keywords: Humidity control materials, Kaolin, Water vapor adsorption Abstract.
In the last decade, there has been a growing interest in so-called mesoporous crystalline materials (MCM-41 type materials).
However, because of high cost of porous silica, another material, selectively leached kaolin has been used to prepare humidity control materials [4-6].
So, this material could be effectively used as humidity control elements in construction materials and other humidity control fields.
