HNTs are in the form of rolling tubes, consisting of a number of aluminosilicate sheets, curved and closely packed with each other [7].
The SAP grains were far larger (90-850 µm), and they did not have a homogenous dispersion and so easily dropped out of rubber matrix after water absorption.

There are number of methods for the deposition of CHAp on various substrates such as sol-gel, plasma spraying, ion-beam sputtering, electrophoretic deposition and others.
The surfaces are homogeneous and smooth and formation of non-uniform irregular size particles with an average grain size of 0.5-2 µm is evident in the SEM photographs obtained at higher magnification.

Conclusions (1) The techniques of salinization prevention for highway subgrade were put forward depending on the project of Qarham to Golmud expressway: Coarse-grained materials such as gravel soil were used as subgrade filler; the gravel separation layer and geotextile barrier layer were set in subgrade structure; (2) The separation layer trial road was built to finally determine the settings of the separation layer and the construction technology

Of which: the abrasion surface of WF1-PTFE1 (Fig.5a) has the least obvious furrow; the abrasion surface of WF1-PTFE1 (Fig.5c) has the most serious scratches with a large number of slender furrows.
Fig.5 Abrasion figure of wollastonite/PTFE composite materials under 250N loading Results and Discussion Test results show that main abrasion mode of WF-PTFE composite materials is abrasive grain abrasion by regarding WF as filler and modifying PTFE by text test and analysis.

In order to accurately describe moisture migration within biological products, mainly foodstuffs (grains, fruits, vegetables, etc), and to explain the effects of drying on the quality of the material, the moisture and heat transfer in individual particles should be understood and accurately represented by a mathematical model.
The coefficient Bn is given by (8) where Bi is the Biot number for mass transfer, and is defined as follows: (9) where h is the convective mass transfer coefficient.

Other way is the grid indentation which is based on performing a large number of equidistantly spaced indentations and their statistical evaluation [4,5].
This scatter is probably associated rather with experimental method than with distribution of Young’s modulus in differently oriented grains (particles) as tungsten has much lower anisotropy ratio (E111/E100) than copper [8].

Thermal conductivity of a material is closely related to the morphology and number of pores.
Structure of the aluminium surface alloyed with the ZrO powder As a result of laser heat treatment within the remelting zone, grain growth was observed (Figure 5 – 6).

Zhang et al. [6] built a 3-D transient thermomechanical model to investigate the cracking and stray grain formation in multi-bead pulsed laser powder deposited nickel-based superalloy.
Number represents sequence.

A number of publications exist in the literature on the synthesis of manganite perovskites.
The size, shape and distribution of the grains were examined using JEOL-JSM 6300 scanning electron microscopy (SEM).
