FSP heals the cast defects such as cavities, coarse eutectic and dendritic structures as well as the coarse primary Si particles.
On the other hand, the tensile properties of cast Al-Si alloys, in particular tensile strength, toughness and ductility, are limited by detrimental microstructure features such as porosity, segregated chemistries, large Si particles, dendrites and thus highly inhomogeneous microstructure [11].
The parent material was characterized by the coarse grained structure while the microstructure in the processed zone was modified by the tool action.

The research showed that high pressure treatment could change protein structure, and then influence functional properties and enzymolysis properties of protein[8].
Effect of high-temperature soybean meal hydrolysates on GSH-PX activity of mouse liver tissue GSH-PX, an important peroxide lytic enzyme widely existing in body, can reduce toxic peroxide into nontoxic hydroxy compounds, promote decomposition of H2O2, reduce peroxidization of polyunsaturated fatty acids of cellular membrane and protect structure and function of cellular membrane from disturbance and damage of peroxides[11], and activity of GSH-PX can affect antioxidation capacity in mouse body.

Reshuffling the crosslinks may form intramolecular bridges (cyclic structures).
(Figure 7 Dynamic vulcanization scheme among BAP, SBR and sulfur) In section 3.3.2, GC-MS analysis shows that many heterocyclic compounds presents such as benzothiazole, dibenzothiophene, benzo[b]naphtho[2,3-d]furan, 2-(methylthio)-benzothiazole, molecular structure figure shown in Table 4, which implies that sulfidic bridges, intramolecular bridges may occur.

Abstract.
Chromosome is the compressed structure for the storage of these codes.
And we believe that the difference between chemical structures of deoxyribonucleotide and ribonucleotide is just the difference of this p-code in stored status and running status.

The asphalt mixture is produced based on both Marshall and Bailey mix design method, which could provide a way to make coarse aggregates perform an excellent structure.
The asphalt mortar formed by asphalt and additives can fill up the spaces left between the aggregate and thus the M2 mixture perform a good embedded crowded structure.

With the increasing corrosion time, compressive strength of concrete increases first and then decreases.This is because concrete compression strength growths and cement hydration decreases due to concrete corrosion in corrosive medium.The above chemistry reaction process is carried out simultaneously.
Based on the combination of the test and the model of corrosion depth of concrete in sulfuric acid presented by Institute of Engineering Structure of Tongji University, he put forward the formula of concrete corrosion depth x:
Durability of concrete structures in acidic water[J].

Highly permeable glassy polymers from the PIM family, and the most used polymer from this class – PIM-1 [8], are materials with great potential for aromatics separation since they contain aromatic rings in their polymeric structure.
