Stereo glasses

The ability to see molecular models or other three-dimensional data on a computer screen was a novelty that further widened interest in computer graphics. Most users required special stereo glasses to see the images in stereo, but some chemists delighted themselves by mastering the relaxed-eye or crossed-eye of looking at the pairs of images. 

Use the 3 key to toggle between stereo 3-D and regular display. To view in 3-D you will need to wear the red/ blue glasses provided with SPARXANView. 

Monocyclopentadienyl complexes of titaninm (Cp TtXs) perform poorly as catalysts for ethylene or propylene polymerization, bnt in the presence of MAO, they polymerize styrene to stereo- and regioregnlar syndiotactic polystyrene, a crystalline material with very high melting point (273 °C) and glass transition temperature (100°C). In this case, the active polymerizing species is a Ti complex (Figure 8). Each styrene monomer inserts in a secondary manner and the stereoregularity is maintained by the conformation of the last inserted unit (chain-end control). 

Kato et. al. [147] applied flow visualization and image processing to measure the velocity and size of glass beads of size, 50, 100 and 200 pm, falling through a pipe using a stereo-imaging technique. 

Fig. 12 Microphotograph of an analyte concentrator fabricated with FAb antibody fragments immobilized to controlled-pore glass silica. The irregularly shaped beads were housed between two frit structures. The analyte concentrator device was connected to two separation capillaries by a Teflon sleeve. The plastic connector was glued to the separation capillaries by an epoxy resin. The entire fabrication process was monitored by an stereo microscope. (For details of experimental conditions, see Ref. 120.)...

With projection VE, stereo pictures are projected by means of a special projection system onto surrounding walls. Projection VE systems allow the user a higher degree of free movement because 3D glasses are the only device that has to be worn. Such a system make it possible to link up several users within a VE application. However, orientation and interaction within the virtual environment is more difficult because of the system s low grade of immersion. 

Figure 7.71 illustrates the change of the glass transition for poly(styrene-co-acrylonitrile) as a function of the run number, defined in Fig. 7.70. The branches of the Barton equation (mA > mg, and mA < mB) are symmetric to the line which extends to the alternating copolymer. This treatment of T can also be applied to triads, and one can use the other equations of Fig. 7.69 as base, but with an increase in complexity. Stereo-specific copolymers consisting of meso and racemic dyads can be treated if the samples of different tacticity have different glass transitions [32].

Make the chromosome spreads. Under the stereo microscope in 1-2 drops (10-30 pL) of 45% acetic acid on a clean slide, tease the material to fragments with a fine needle, isolate the meristem, and remove all other tissue from the slides, in particular the root cap, which is tough and prevents squashing see Note 5). Apply a cover slip. Carefully tap the cover slip with a needle and then gently squash the material between glass slide and cover slip see Note 6). Check the preparation under a phase contrast microscope.
