Introduction Ginkgo seeds, as a precious nut, containing starch, crude protein, crude fat[1], a large number of VBl, VB2, VC, VD, carotene, niacin, nuclear flavin, phosphorus, potassium, calcium, magnesium, iron and other 25 kinds of trace elements[2], have been used as tonic and food for long time in China.
This is because along with temperature rising protein denatures, and the exposure of a large number of non-polar groups weakens the interaction between ginkgo protein and water.

Another sub-unit consisted of parallel retained austenite lenticular grains, inclined to the main retained austenite layers by about 30o.
The average number density of C-rich clusters and fine carbides in Steel 1 was ~7×1011 m-3.
The formation of fine carbides was found in the bainitic ferrite of both steels with higher number density in Steel 1.

That said, the revival of interest in EPD that followed the publication of the extensive review by Sarkar and Nicholson in 1996 [4] has generated, directly or indirectly, a great deal of subsequent work which has resulted in a number of far from fanciful potential applications .
The first stage of sintering is limited to the growth of interface contacts, and the development of the initial grain or phase boundary facets occurs almost immediately.
A number of processing defects had to be eliminated in the process of development, most notably gross porosity associated with poor packing of oversize aggregates and wedge formation during deposition due to incipient instability of the dispersion.

Several studies have been devoted to the synthesis and tribological performance evaluation of ceramic oxide coatings deposited on a large number of Al alloys obtained through the MAO process[3-5].Although several investigations have been carried out, the complete tribological characteristics of MAO coatings high stress levels have not been studied.
At a number of randomly selected locations, the scanned regions were photographed and these micrographs were subjected to analyze the coating characteristics.
The surface micrograph exhibits a dense ceramic coating, witch contains many grains and few ostium with various sizes.

However, due to the low atomic number of Si (Z = 14), its absorption efficiency is low.
A great advantage of compound semiconductors is the possibility of growing materials with a wide range of physical properties (band gap, atomic number, density).
These are interesting findings and, to our knowledge, have never been reported before, especially for single crystal semiconductors (i.e. no grain boundaries).

The surface roughness of the material and the grain size and processing temperature were affected the wear rate.
Different solid lubricant mixed with other different materials, and embedded in the ceramic tool’s position, the number and the shape of the groove, sizes will produce a huge impact on tool performance, but these data have no professional books for reference, only through the large number of experiments improve gradually, and find some better ways.

Introduction With the rapid development of the automotive industry, the number of waste tires increased dramatically.
All over the world there are more than 1 billion scrap tires each year and in China the number of it is from 5000 to 60 million, and the increasing rate of it is about 15% per year.
This test uses compulsory concrete mixer to mix, vibration close-grained to form concrete.

Compared to other nanostructures, the nanotube is the most desirable form, because the interaction of bone tissues or cells occur at grain boundaries of nanotubes [10], one-dimensional titanium oxide nanotubes have the greater specific surface area and higher mechanical strength [11].
Based on the results of elemental characterization by EDS, Fig. 3 shows that those are the incorporation of F- ions from NH4F electrolytes attached around the nanotubes, indicated by red cross symbol number 1, the weight percent of fluoride element is quite high, which is 20.22 wt%.
Other than that, there are also titanium oxides which are incorporated with fluoride, indicated by red cross symbol number 2, with the weight percent of oxygen elements 24.27 wt% and fluoride 20.67wt%.

Biodegradable polylactide, as a consumable material for 3D printers, has a number of advantages over traditional petroleum-based plastics, but it currently has a relatively high cost and in some cases lacks strength [6].
The composition of the samples and their processing modes Sample number Filler processing temperature Ratio PLA / filler 1 - 100/0 21, 22, 23, 24 160, 180, 200, 220 70/30 31, 32, 33, 34 160, 180, 200, 220 50/50 41, 42, 43, 44 160, 180, 200, 220 30/70 It should also be noted that objects often change their specified dimensions, tightening or contracting after printing on a 3D printer.
According to the schedule the size of wood-based filler decreases at high temperature processing, and therefore the grain size of the product obtained from it decreases as well.

A majority of domains in a sample crystal of partly stabilized zirconium dioxide 2.8 % Y2O3 are elongated (Fig. 1), a small number of narrow domains were identified (Fig. 2).
Figure 2 – Micro-indentation diagram of a partly stabilized zirconium dioxide crystal with 2.8 % Y2O3 Mechanical properties (Table 1) to be dependent on anisotropy and variable in crystallographic directions are high due to lacking inter-grain boundaries in crystals.
They depend on a number of physical and chemical processes, e.g. friction transfer of a coupled element material, uncompleted removal of wear products from the contact area, their adhesion on friction surface of samples, full or partial oxidation of transferred material etc.
