چکیده
Recently, demand of high-functionality for artificial polymers increases more and more in the various fields of materials such as optics-photonics and electronics. Especially, development of synthetic processes for the polymers having clear helical structure attracts large interests from the viewpoint of not only for creation of novel functionality and functional materials but also for elucidation of fine functionality displayed by helical biopolymers. In this review, recent research development and trend of artificial helical polymers and supramolecules are categorized and discussed focusing the relation between the fundamental molecular structure and capability of achieving induced/fixed helical conformation.

Wave Motion and Stop-Bands in Pipes with Helical Characteristics Using Wave Finite Element Analysis
Pipes are widely used in many industrial and mechanical applications and devices. Although there are many different constructions according to the specific application and device, these can show helical pattern, such as spiral pipes, wire-reinforced pipes/shells, spring-suspension, and so on. Theoretical modelling of wave propagation provides a prediction about the dynamic behavior, and it is f...

متن کاملData mining for decision making in engineering optimal design
Often in modeling the engineering optimization design problems, the value of objective function(s) is not clearly defined in terms of design variables. Instead it is obtained by some numerical analysis such as FE structural analysis, fluid mechanic analysis, and thermodynamic analysis, etc. Yet, the numerical analyses are considerably time consuming to obtain the final value of objective functi...
متن کاملComparison of convective heat transfer of turbulent nanofluid flow through helical and conical coiled tubes
Application of nanofluid and coiled tubes are two passive methods for increasing the heat transfer. In the present study, the turbulent flows of water and nanofluid in coiled tubes heat exchanger were numerically studied. CuO-water nanofluid containing 1 vol% copper oxide nanoparticles was used and single-phase approach was considered for nanofluid flow. The effect of different geometrical para...
