So far, CS technology have penetrated into many fields, such as materials science and engineering, physics, chemistry, metallurgy, machinery science and engineering, etc.
A sandwich structure of Mo-TiB2-Mo or Mo-TiC-Mo was formed, both have reaction transition zone.
He [18] prepared (TiB2+Fe)/Fe structure material by CS welding, it was found that well-bonded interface could be obtained, the joint fracture occurred in the position of TiB2+Fe metal ceramic layer, rather than along the interface between TiB2+Fe metal ceramic layer and the Fe substrate.

There are residual charges on the surface of the lattice if the structure of the lattice is unchanged after La3+ and Ag+ replacing Ca2+.
The bands at 1411, and 1456 cm-1 are caused by the carbonate groups incorporated in the La/Ag/HAP composite structure and the background carbon dioxide (CO2) within the atmosphere.

(1) Physical blockage during heap leaching mainly performs the modification to pore structure, which is controlled by fine particles migration and sediment (see Fig. 6).
Physical blockage is gradually eliminated after 4 hours, when chemical precipitation begins to change the pore structure of ore heap.

H3PO4 with different concentrations is studied its effect on the surface structure and iodine number.
Functional group analysis confirmed that the P-O group introduced in the biochar structure.

As can be seen from Table II, the activation energy of the oils follows the sequence Erapeseed oil < Emethyl ester structure of oils.
Results showed that the activation energy of epoxidation was in the order of rapeseed oil < fatty acid methyl ester < soybean oil < sunflower oil, which was relative to their compositions and structure.

When it comes to foundations, bridges, dams, tanks, or other waterproof structures the key issue is to improve such features as tightness, vapor permeability but also flexibility.
The third variant corresponded with an insulation coating that was very vaporpermeable (weight: 0.70) but prevented the water (weight: 0.15 – insulations that remove the vapor from the inside of structure and counteract the condensation).

The XRD data were further analyzed qualitatively and quantitatively by means of a general structure analysis system (GSAS) software [13].
Hence, the La+3 ions have succeeded in replacing some of the Ba+2 ions in the BaFe12O19 structure for x ≤ 0.1.
