Extreme examples for these two approaches are "random flight" model of polymer chain and ab initio calculation of polymer structure.
Such conformational elements (called secondary structure of a protein) make 3D-arrangement in space called tertiary structure.
For example, globular proteins by folding the elements of secondary structure together make a globular shape of the molecule.
Again one faces the problem of folding of polymer chains, confirming that it is quite a fundamental issue of polymer structure.

The Comparison of Different Preparation Methods of Catalysts for Furfural Hydrogenization to 2 - methyl furan Zengxin Li1,a, Tongzhu Han2,b,wenxia Guo3,c and Guoming Wang4,d 1,2,3,4Department of Chemistry Teacher’s College Qingdao University, Qingdao, China alizx57@126.com, bzthan1991@163.com, cwxguo@126.com, dgmwang_pub@163.com, Key words: furfural hydrogenation; copper chromite; chromium; catalyst ;2 - methyl furan Abstract.
Three different kinds of preparation methods were contrasted and studied to furfural hydrogenation catalyst for 2 - methyl furan production.Cu, Cr-based catalysts are prepared by three different methods, and the differences were also studied in the structure of these catalysts and their catalytic properties on furfural hydrogenation reaction.
By thoroughly comparing metal grain size, degree of metal reduction, the catalyst activity and selectivity of those catalysts, the differences in the structure among these catalysts were discussed, based on which catalytic properties in furfural hydrogenation reaction were studied to improve the yield and the catalytic activity.
Summary Cu, Cr-based catalysts are prepared by three different methods, and the differences were also studied in the structure of these catalysts and their catalytic properties on furfural hydrogenation reaction.
Special attention has been focused on the unique structure of amorphous alloys, which may be of importance to the higher and special selectivity than those corresponding crystalline alloy.

Raman analysis shows the presence of wurtzite hexagonal ZnO in all the films and presence of anatase structure of TiO2 in the film deposited at 200 W.
From previous study, many efforts have been made to modify electronic structure of metal oxide, in order to enhance the activity of the catalyst [4] in the near-UV and visible spectral ranges, because of the individual intrinsic photocatalytic activity of pure nano-TiO2 and nano-ZnO films or nanoparticles is considerably weak [1, 5].
For ZnO, the peak at 444 cm-1 represented the characteristic peak of the Raman active mode of the wurtzite hexagonal ZnO or the oxygen atom in the ZnO hexagonal structure [6, 12, 13].
In addition, the peak at 143 cm-1 and 200 cm-1 represented the anatase structure of TiO2 in the film deposited at 200 W.

The results indicated that the Li2FeSiO4 as-synthesized are orthorhombic structure.
Similar to LiFePO4, the Si-O bond strength in the lattice of Li2FeSiO4 is very strong, and thus shows high security because the structure maintains stability under high temperature or overcharge[8].
For all samples, the main diffraction peaks are well indexed base on an orthorhombic structure (space group Pmn21).
All the obtained Li2FeSiO4/C samples had a monoclinic structure with the space group Pmn21, and the grain size became larger by increasing the sintering temperature.
