The cause for surface nanoscale porosity in Mg alloys has been attributed to factors including solidification shrinkage, grain size, cooling rate and gas dissolution [15].
The number above each bar graph indicates the percentage of adhered BMSCs relative to original seeding density.

A number of authors have theoretically and experimentally proved, that all three types of transfer occur in the range the following coefficients of filtration (table 1).
Hydroabrasive wear of the collector tunnel lining begins with the leaching of cement paste and the separation of grains of coarse and fine aggregate, as a result, the tunnel lining becomes more rough, and this, in turn, exacerbates the wear.

Additionally, discrepancies between retailer and manufacturer counts for returned merchandise can lead to unnecessary deductions and the extra labor on both the manufacturer and retailer sides to resolve the deductions. (2) Visibility of product by serial number through the supply chain will allow manufacturers and retailers to better control the winding down of discontinued or about-to-expire products, reducing price markdowns. (3) It will aid in managing recalls of products, saving time and labor.
This is emphasis on the dynamic effect compare with section 4.2. it is not the deployment of RFID tags, antennas, and readers by itself that will push the organizations ahead of their competitors, but it is the way an organization uses the fine-grained and real-time RFID data to improve its business processes that will determine the extent of potential benefits to be obtained from RFID [10].

As shown in Fig. 1, the prepared Fe3O4 materials are spherical and not uniform with grain sizes in the range from 200 nm to 500 mm.
Next, the discharge specific capacity improves with increasing cycle number and achieves to 678 mAh g-1 after 80 cycles.

Dalian University of Technology[12] has developed magnesium alloy complex activating flux, which has made weld bead penetration increase by about two and a half times, while improving phase composition of weld and avoiding the formation of brittle phase in joint, with fine grain and high tensile strength.
The number of electrons has tended to decrease and the electrical conductivity of arc has weakened, finally leading to the contraction of plasma (the whole arc not contracting but expanding[11], as shown in Fig.1), heat and arc force have focused to make the weld bead penetration increase.

There have been already reported a number of palladium (Pd) and platinum (Pt) Schottky diode gas sensors using InP or GaN materials.[1-17].
The graphite, seen on the left side, consists of grains of the size around 1 mm.

When the SPS sintering pressure is 30 MPa, the microstructure at different sintering temperatures shows that when the samples were sintered at 1000 oC, some spherical particles of the AlCoCrFeNi high-entropy alloy in the sample 1 are clearly observed (Figure 3a), and the sintering of the grains between the particles and the particles is not completely formed.
When the sintering temperature increased to 1100 oC, a large number of nanoscales meshes appear in the matrix alloy in the sample 6.

Mechanical grinding and polishing always consisted of grinding at SiC paper down to the 2000 grit size, polishing with diamond-based suspensions with grain sizes 9-1 micrometer.
Fig. 4 Ferritic-pearlitic sample after test, ductile cup and cone fracture surface with dimple morphology Fig. 5 Ferritic-pearlitic-bainitic sample after test, mixed fracture with brittle fracture facets Discontinuous tensile tests with EBSD acquisition In the next step, several discontinuous tensile tests were carried out at 42SiCr steel with increasing number of stops for documentation of microstructure development and EBSD patterns.

The mechanical properties of metals and alloys can be drastically improved upon a decrease in their mean grain size down to 100 nm by using the methods of severe plastic deformation.
This approach provides the delivery of a large number of mesenchymal stromal cells to the implantation zone.
