By engineering the organic chemistry of polymers, material properties can be expanded beyond limits, to include optical, electrical and mechanical properties and heat resistance.
Organic polymers are structurally flexible materials that are readily formed into single-mode planar waveguide structures in integrated optical systems.
By tuning the molecular structure and the molecular weight, these polymers will have a high cross-linking density.
These polymers have a highly stable aromatic ring structures along the backbone of the polymer chain.
In addition, since there is a limited number of polymers tested for passive waveguides, there is no limit in using polymers that have similar building blocks and based on similar chemistry.

From present study it is found that AmN and AmP are stable in NaCl – type structure under ambient pressure.
In the NaCl structure the corresponding lattice parameters are 2.890 and 3.124 Å respectively.
For a given pressure, a stable structure is one for which enthalpy has lowest value and the transition pressure (Pt) is determined at which the enthalpies of two structures are the same.

Compared with TiO2 nano-membrane, the XRD analysis shows that no significant shift in the crystal structure is presented because of silver ion-doping.
The films heated to 400°C(Fig.1A-b) and 450°C(Fig.1A-c) with featureless pattern suggests an amorphous structure while three distinct crystalline peaks at 25.3°, 38.6°, 48.1°. 2θ observed in the samples heated up to 500°C(Fig.1A-a,d,e,f) attributed to anatase crystal structure (JCPDS 21-1272) which has the best photoactivity of all.
From the patterns, it can be told that silver ion-doping does not cause any significant shift in the crystal structure compared with pureTiO2, and nice anatase crystal structure with preferable photoactivity can be already obtained at 500°C. 2.2 FTIR determination The insights into TiO2 heated to 500°C and Ag/TiO2 heated to 400°C, 450°C, 500°C, 550°C respectively are provided by IR spectrum in Fig.1B.

Fabrication and optical study of Ag@SnO2 core-shell structure nanoparticle thin films[J].

This is due crystalline of SMR CV60 structure which induce more strain crystallization when stress was applied.
This is because of the bulky group (styrene) in SBR compounds which has given amorphous state to the SBR structure.
In addition, polymer chain structure has given more impact towards the mechanical properties of rubber materials.

The modified coal powder particles can be dispersed equally in rubber and form physical and chemical crosslinking structure with rubber.
Coal contains large amounts of aromatic structures, high carbon content and electrophilic active sites of aromatic structures can react as substituent, alkylation, acylation [1].
FTIR, TGA and CAMI were performed to characterize the structures and properties of M-coal and N-coal.
It is like due to interaction between the active chain or group of coupling agent and macromolecular chain of SBS form network structures [17].

The half-lives of the hydrolytic reactions of simple phosphate diesters are on the order of thousand years, although their spontaneous hydrolysis is thermodynamically favourable. [1-4] Because the natural enzymes is complex, expensive and of unstable structures.[5]Then, many researchers have already concentrated on the study of artificial enzymes.With complex and more stable chemical structure, these mimetic enzymes have similar catalytic function to natural enzymes.
Effects of the complex structure on the rate of PNPP catalytic hydrolysis Generally, the enzymatic catalytic activity and selectivity are correlated to the enzymatic structure.
The mimic hydrolase used in this paper shows similar effects of the structure to the natural hydrolase in the BNPP catalytic hydrolysis.
