This article mainly discuss the interface structure and optical property of Au/Ag NPs coated with DLC films.
Raman spectra is the best way to obtain the detailed bonding structure of DLC films.
S only depends on elements and has nothing to do with chemistry bond, so sp2C bond and sp3C bond have the same sensitivity factor.

Synthesis and Properties of Hybrid Curing Siloxane Modified Epoxy Resin/Polyurethane Acrylate Coating Jungang Gao*a, Cong Tianb, Xiaojing Wuc College of Chemistry and Environmental Science, Hebei University, Baoding 071002, China agaojg@hbu.edu.cn, btiancong123@yeah.net, cwuxiaojing823@126.com Keywords: Polyurethane acrylate , Epoxy resin , Siloxane , Hybrid cure ,Kinetics Abstract.
But the impact strength decrease with the increasing of the amount of MAPTMS, this is because of the MAPTMS can participate in crosslinking curing reaction, and the methoxy of MAPTMS can hydrolyze to form a crosslinking structure of -Si-O-Si-, which will increase the cross-linking density of folm, so the hardness increase, the impact strength decrease.
The higher Tp, the higher Tg is, which depends on the molecular chain structure and material morphology.

Consequently, a hydrating cement grain was best represented by a mosaic structure, with superplasticizer molecules mainly adsorbed on ettringite and some on monosulfate and C–S–H nucleated at surface [20].
Therefore, not only the superplasticizer trunk, but also the side chain possessing a coiled structure may adsorb on the surface of cement [8,9].

Structure of the Cellular Automaton Model The model for the mesoscale prediction of spherulite growth in polymers is designed as a 3D cellular automaton model with a probabilistic switching rule.
Fig. 2 shows an example of a simulation of the evolution of the spherulite structure for a calculation with the assumption of a constant nucleation rate.

SiO2 has many advantages such as higher surface area, peculiar pore structure, non-corrosiveness, low-cost and regeneration.
The characteristic diffraction peaks of H4SiW6Mo6O40 that explored at 8.0°, 10.4º, 20.7º, 25.5º, 29.2º, 34.5ºand 37.8º can be assigned to the diffraction characteristic peaks of crystalline H4SiW6Mo6O40 Keggin structure.

Several etchants were used to reveal the grain size structure and the precipitates existing in the matrix of aluminium.
Kroll's reagents was used in 2024-T3 and a modified Poulton's reagent in 5083-O and 6063-T6 alloys to reveal the grain structure.

Magic angle spinning nuclear magnetic resonance spectroscopy (MAS-NMR) has been successfully used for investigating the structures of various P-containing silicate or aluminosilicate glasses [3].
The peak at -20 ppm is probably due to a phosphate ion coordinated by one or more Al ions, which has a similar structure to aluminium phosphate described later.
