Figure 2.42 Micro mixer geometry with staggered groove structures on the bottom wall, as considered in [137], The top of the figure shows a schematic view of the channel cross-section with the vortices induced by the grooves. At the bottom, confocal micrographs showing the distribution of two liquids over the cross-section are displayed.

The CSN architecture shows similarity to that of the lid. Both complexes have an asymmetric arrangement of their subunits and exhibit a central groove structure...

P 67] Simulations were made following experiments made previously [156], Therein 0.11 mM Rhodamine B solutions in 20 mM carbonate buffer were mixed with the same carbonate buffer. For the buffer solution, the physical properties of water were approximated. For Rhodamine B, a diffusion coefficient of 2.8 10-6 cm2 s-1 was taken. Electroosmotic flow was applied for liquid transport. For all of the walls in the domain the electroosmotic (EO) mobility was set to 3.4 10-4 cm2 V-1 s 1, which corresponds to a zeta potential (Q of-44.1 mV. The electric field in the outlet channel was 1160 V cm-1. The Reynolds number was 0.22. The electric field strength was set low in order to decrease diffusive (pre-)mixing prior to the groove structure. 

Figure 1.159 Concentration profiles of an injected plug of Rhodamine B traveling over a four-groove structure in a micro channel at two different groove-to-channel mobilities rEOM and for an unstructured channel as reference case. This plot describes the axial broadening of the pulse signal. In addition, cross-sectional concentration profiles are given to analyze the corresponding impact on mixing [156] (by courtesy of RSC).

These results can be understood as follows. The presence of a strong inter-base interaction in the GC strand (three HBs between G and C) makes the groove structure quite rigid, and hence the interaction of water with the DNA atoms is frustrated. The DNA atoms do not undergo deformations in position to accommodate the preferred orientation of water to form a stable tetrahedral structure. The opposite is true for the AT minor groove (two HBs between A and T), where the intrabase interaction is less compared to that for the GC strand. Here the groove structure can be deformed in such a way that water molecules can attain their preferred orientation to form a stable tetrahedral structure. 

Schematic overview of the detection groove structure. In the nanochannel structure (7-2), a deeper groove (i) is etched to enhance the detection. With this type of groove (with a depth of 4.75 pm see side view), a fivefold decrease in the detection limit could be obtained, (b) Outline of the automated injection system, (a) The supply channels in the PMMA connect to a cavity above the injection micro-well, (b) Wyko (optical profilometry) scan of the backside of the etched well, showing the position of the injection slit in the channel, together with the non-etched channel spacer regions (7, 2) delimiting the lateral extent of the channel and the non-etched region (3) preventing the mobile phase that is present in front of the channel to enter the channel. The flow direction is indicated by the arrows...

In a model put forward by Indenbom, the ITIES is considered as an elastic film in which forces of interfacial tension counteract the forces of an external electric field [64]. This causes a potential-dependent compressed grooved structure of the interface at which ion transfer takes place when the compression reaches a critical state. The validity of this picture will rely on detailed molecular dynamics studies of the microscopic features of ion transfer across ITIES. In this connectionit is relevant to mention the work of Cunnane and coworkers in which the kinetics of ion transfer across a monolayer adsorbed at a liquidjliquid interface is discussed in terms of the energy required to form a pore of a size similar to that of the transferring ion [56].

Photopolymerization is just one of the available methods for copying discs. It has been used for several years in the large scale production of video discs. Today, injection molding is also used. In addition, photopolymerization serves for the replication of flexible molds as well as for making the pre-groove structures on... 

Table 2.4 summarizes specifications for rubbing cloths used for display manufacturing. The groove structure caused by rubbing resembles the structure of the textile of the rubbing cloth, and this has secondary effects on the alignment of the LC.
