Flexible solutes

Figure A3.8.3 Quantum activation free energy curves calculated for the model A-H-A proton transfer reaction described 45. The frill line is for the classical limit of the proton transfer solute in isolation, while the other curves are for different fully quantized cases. The rigid curves were calculated by keeping the A-A distance fixed. An important feature here is the direct effect of the solvent activation process on both the solvated rigid and flexible solute curves. Another feature is the effect of a fluctuating A-A distance which both lowers the activation free energy and reduces the influence of the solvent. The latter feature enliances the rate by a factor of 20 over the rigid case.

If for very dilute solutions of neutral rigid spherical species, the hydrodynamic theory for the hindered transport previously developed may be considered as at a mature stage, in sharp contrast is the situation for charged and/or flexible solutes in more concentrated solutions where solute-pore and solute-solute interactions remain largely unevaluated. Other important gaps in the present knowledge concerns the prediction of solute adsorption in the pores and its effect on measurable transport properties [9].

Tool-electrodes can be fabricated in several ways. An excellent and flexible solution is wire electrical discharge grinding (WEDG), which is well suited for microfabrications [85]. An alternative way is to use anodic etching of tungsten. As shown by Lim et al. [82] very thin cylindrical electrodes (down to 50 pm) with controlled diameters can be fabricated. The important point is to use a high concentration of the electrolyte (typically 5 M KOH) and relatively high current densities around 10 mA/mm2. Thus, the diffusion layer around the electrode can be controlled in order to achieve various tool shapes by anodic... 

Figure 18. PI-QTST activation free-energy curves as a function of the proton asymmetric stretch coordinate for a A-H-A proton transfer model (see Ref. 77). The solid line depicts the classical free-energy curve for the solute in isolation with a rigid A-A distanee, while the dotted line is the quantum free energy for the rigid, isolated solute with a fully quantized proton. The long-dashed line is the quantum free-energy curve for the isolated solute in which the A-A distance is allowed to fluctuate. The dot-dashed and short-dashed lines depict the quantum free-energy curves for the rigid and flexible solutes, in the polar solvent.

On one hand, the flexibility of the polymer introduces some very attractive properties, e.g. flexible, solution processible, easy to functionalize, and so on, to this category of materials on the other hand, the structure variation causes tremendous variation in the electronic transport properties of CPs. The overall structure of a CP nanowire is determined by material organization at several length scales. Therefore, unlike some of the...

In Figure 7, each circle depicts the research database of a department in a chemical/ pharmaceutical company. The union of all circles represents the chemical-scientific database of the company. Intersecting circles indicate data sharing and communication between departments. Since each department views its data in special ways and may select particular software, it is difficult to design a chemical-scientific database system that treats all unions and intersections. A chemical-scientific database system that can be customised for the various data views is a flexible solution to this difficulty.
