Numbers going from 1 to 5 indicate the boundary conditions for calculating the transmittance of water vapor diffusion.
Symbol A means soft wood (flow perpendicular to the grain) and symbol B means thermal insulation.

Because of a number of desirable physical and chemical properties exhibited compared with traditional molecule sieve materials such as high surface area and pore volume, high thermal stability and ease of surface modifications, mesoporous materials afford many potential application of chromatography, cosmetics, catalyst, and adsorption, and is expected to play a tremendous role in material science in the future [3].
For PEG-6000, it might be joined with CTAB in some way and worked as dispersing agent to suppress growth of grains.

In addition, water or other fluids may affect the wear rate of a material by a number of mechanisms, primarily (although not exclusively) as agents of corrosion and/or lubrication [5].
This would be rational if one notices that, aside from the factors such as hardness, toughness, carbide grain size, phase distribution, binder phase content, and microstructure, the testing conditions including the counterpart material could also have prominent effects on the friction and wear behavior of the WC-Co coating [3,6,8].

Table 2 Microhardness of electroless Ni-P deposit Hardness (HV) Ponit number 1 2 3 4 5 Average value Without heat treatment 699.1 774.8 707.7 691.1 739.3 722.4 With heat treatment at 400 o C 968.8 1002.7 985.4 958.2 978.6 978.7 3.3 Immersion tests The corrosion rate of W-Cu substrate and Ni-P deposit in different corrosion mediums are shown in Fig.3.
The SEM result shows that the Ni-P alloy deposit has a fine-grained structure with a uniform distribution.

It also has a spongy structure and exhibits multigrain agglomerations of well-crystallized grains that might be due to high surface energy of nanoparticles and dipole interactions between ferrites materials.

The experimental density (ρexp) of the HEA was measured using the Archimedes method (densimeter) whereas the theoretical density (ρtheo) was calculated using a rule of mixtures as given by Eq 1 ρtheo=i=1nCiAii=1nCiAi/ρi (1) where n, Ci, Ai and ρi are the number of constituent elements, weight fraction of the individual elements, the atomic weight of the individual elements, and the density of constituent element respectively.
The Mg-Al-Zn phase has many diffraction peaks, this means it presents different grain orientations.

Over last years, nanosized grain materials have gain increasing interests arising partially from the absence of extended defects in these particles.
PZO is a linear Zr-O-Zr chain coordination polymer, with a molecular weight of 1000-2000, and the coordination number of Zr is 8 (15). 1HNMR (CD3OD, 400MHz and d ppm): 3.6 (w, 2H, -CH2-, keto form), 3.1(s, 1H, =CH-), 2.1(m, 3H, CH3CO keto form), 1.3(s, 3H, CH3CO enol form); FTIR (n, cm-1): 3415, 1590, 1530, 1483, 1368, 1280, 1027, 932, 652, 543 and 428. 1.2 Synthesis of preceramic polymer - PZS PZS was prepared by the reaction of polyzirconoxane (PZO) and salicyl alcohol.

It was found that the CdSe nanoparticles contained some defects or dislocations, which might be caused by the stacking faults at the surfaces and the grain boundaries during the CdSe nanoparticles formation.
The formation of small CdSe clusters with certain "magic" agglomeration numbers [11] might have the reason that particle growth proceeds via coalescence, i.e., two small clusters fuse to a larger one.

In our precedent works[12,13] Pt thin films have been deposited by the same technique; there are clearly shown the nanostructured nature of these films and the moundlike structure of their surfaces, due to the Pt grains.
This quantization is estimated by the parameter N ≈ (3n/π) 1/3 d, which is the number of subbands occupied by the electron gas.

It is expected that the presence of a large number of UNCD crystallites in the films sharpens the sp3 peak because the wave function around the Fermi level in crystallites must be uniform rather than that in the amorphous structure.
We believe that the grain boundaries terminated by hydrogen atoms are responsible for the large sp 3-CH peak [14, 15].
