The Ni foam surface is smooth and grain boundary is clear and easy to distinguish.
From Fig.5 (a)-(c), with the extension of etching time, the number of pores in the strut is increased and the size of the pores becomes larger, until the surface of strut becomes rough.
The elongated time contributes to the more number of pores and the large specific surface area.

Powder from, Tin, Bismuth Zinc and Cooper of (99.999) purity, have (120-140) µm grain size were used.
The numerical numbers are , 1.Sn-Bi, ,2.Sn-Zn .
The numerical numbers are, 1.

The fibers should be dispersed uniformly in the structure, as well as dispersed grains of the coarse fraction of aggregate in plain concrete.
For randomly dispersed fibers it is only a very small number of the fibers that is parallel with the principal stress, or within a small angular deviation.
The progressive extracting and an increase of the number of thin cracks give toughness to the SFRC.

A number of requirements are imposed on medical materials, which can be divided into three groups: 1.
Alloy Ti-6Al-4V has a globular (α + β) -structure (Fig. 1 b), and in alloy 316L, a typical single-phase structure is formed, represented by polyhedral grains of the γ-phase (Fig. 1 c).
The lowest plasticity is observed in the cobalt alloy, which is apparently due to the cast state and the presence of a large number of intermetallic phases and chromium carbide.

The grain size after heat treatment at 900 °C was about 100 nm (Fig. 2A).
When the green compacts were sintered at 1200 °C (Fig. 2B), the grain size was increased to a value close to 1 µm.
In contrast with the control surface (tissue culture plastic), the number of cells that proliferate on the scaffolds in all cases, e.g.
By repeating this measurement for a large number of angular positions of the sample and by using a tomographic reconstruction algorithm, it is possible to reconstruct the 3-D b map.
Unfortunately, although a number of details can be observed with holotomography, it is still hard to distinguish very soft tissues such as vessels.

The resulting glycerol has a blackish-brown color that comes from fine grains of activated carbon that can still pass through the pores of filter paper during filtration.
Characteristics of Edible Film without Glycerol Addition from Used Cooking Oil Making an edible film with the use of potato starch of 3 grams and without the addition of glycerol from used cooking oil (0% glycerol) produces a white solution resulting from the color of potato starch which will then thicken at 700C, this is because the gelatinization temperature or the temperature at which starch grains break is 52-800C (Lismawati, 2017) and the gelatinization temperature of potato starch is 65-680C [15].
The tensile strength value is large also due to the large number of hydrogen interactions contained in the edible film so the bond between chains is stronger and requires great energy to break the bond [10].
This is because the addition will increase the stretching of the intermolecular space of the edible film matrix structure (increase flexibility) and decrease the number of hydrogen bonds (reduce fragility).
Reducing the number of hydrogen bonds increases elongation but decreases the tensile strength of the edible film.

Here bioleaching of copper slag material with a copper content of about 1 % (grain size < 63 µm) and fayalite (Fe2SiO4) and magnetite (Fe3O4) as main mineral phases was tested in aerobic shake flask experiments with a mixed culture of Acidithiobacillus ferrooxidans, Acidithiobacillus thiooxidans and Acidiphilium spp..
Additionally the number of acidophilic sulfur- and iron(II)-oxidizing bacteria was determined by MPN-cultivation [5].

The dissolution of hemicellulose destroying connection between carbohydrate and lignin, and a small number of lignin also has been removed.
Average number of fiber fines fell by 10.49%.
On the one hand, because major constituent of Poly-xylose class hemicellulose is Arabia candy 4-O-methyl glucuronic acid xylose in the grain, in acidic conditions, Arab sugar-based (acid unstability) were removed in the hydrolysis process.
Absorption peak in the wave number at 897 cm - 1 was characteristic absorption peak of β- D - glucose sugar.
Fiber surface of untreated bagasse are surrounded by a large number of fine fibrosis material and small components.

.%) of the same inoculant in powder (grain size 0.2 to 0.6 mm) was made at the bottom of one of the cavities while other additions could be similarly placed in the two other cavities.
A nodularity index NI was also evaluated as the ratio of the number of spheroidal particles to the total amount of graphite particles.
Spot analysis was performed on inclusions and the number of each kind was evaluated, see Table 2.
The number of inclusions is much higher in Ce-treated than in Mg-treated alloys, they are mainly (Ce,La)S and CeP in the former, MgS in the latter.
When the number of particles was measured, average values per mm-2 are given, otherwise the observation is noted with ●.

Image analysis Number of fibers and cross-section area occupied by fibers were determined with ImageJ software.
Average number of six cross sections of a brick with 3cm long fibers is 272 fibers and they cover 6.71% area of a brick cross section.
In case of 2cm long fibers, average number of fibers for a cross section is 280 fibers and they occupy 6.46% area of a brick cross section.
Number of fibers and area occupied by fibers in a cross section is shown in Fig. 6c.
Number of fibers in case of 2cm length fibers is slightly higher due to small length of fibers.
