Fig. 13. (a) The CMOS inverter circuit. The FET circuit symbols emphasize that MOSFETs are actually four-terminal devices in which the -substrate is connected to b DD for the PFET and the -substrate is connected to the ground for the NFET. Note the conventions on drain location for the PFET and NFET. (b) Corresponding cross-sectional view roughly to scale for a 2-Jim CMOS process, where Brepresents silicon, D Si02, fZl polysilicon, and Q... 

A great number of researches have so far been carried on the incorporation of poly(IPAAm) and its copolymers in various biomedical devices, utilizing soluble/insoluble or swelling/deswelling processes in the temperature range of LCST. As overviewed by Okano et al. [44] these include drug delivery system (DDS) solute separation concentration of dilute solutions immobilization of enzymes detachment of cultured cells coupling to biomolecules, and other aspects.

Future of DDS can be predicted to some extent for the next ten years. To go beyond that, e.g., to 20 years from now, would be very speculative. Some of the drugs currently used would disappear from the market and no one knows for sure what drugs would be discovered 20 years from now. Some of the diseases may be partially eliniinated and new variants may appear, particularly in infections. With this scenario, it would be difficult to say what methods will evolve to deliver the drugs that we do not know as yet. Some of the drug treatments may be replaced by devices that do not involve the use of drugs. 

Figure 4.1. Three potential approaches to perform simultaneous, suppressed, and non-suppressed detection. (a) Split stream approach. DD, dummy dispersion device suppressed detector, D , nonsup-pressed detector. Restrictors R1 and R2 are adjusted to provide the same residence time and flow rate in each of the branches, (b) Single column approach. D precedes the suppressor, (c) NaOH introduction approach. A small constant quantity of NaOH is introduced after D no restriction is placed on eluent NaOH concentration [4].

The rise of flows movement rate w and divergent-convergent section number Ns from 1 to 4 leads to the reduction of surface-volumetric diameter of disperse phase drops and correspondingly to the increase of specific phase interface (Fig. 3.32) that in the case of fast processes intensifies proceeding of chemical process in the whole. Irrationality of application of tubular turbulent apparatus with divergent-convergent sections number Ns more than four makes these devices compact (their length doesn t exceed 8-10 calibers L/dd) and simple in manufacture and exploitation.
