Since many of the aromatic polymers studied [e.g., poly(n-hexylphenylsilane)] are also quite rigid in solution and optical microscopy studies on concentrated solutions often show signs of long range order, a partially oriented sample of this material was prepared by shear flow extension. Third harmonic measurements at 1.064 /im on partially oriented films prepared in this...

Optical microscopy studies were performed with a Reichert Thermopan microscope with crossed polarizers. The magnification used was 80X. 

Measurements showed that, even in the chloride-free Na2S04 solution, MnS inclusions are dissolved [7]. Since the inclusions are dissolved rather slowly and no stable pitting occurs, the dissolution processes can be assigned to single inclusions quite well. Measurements at sites with inclusions are shown in Fig. 10. Two local potentiodynamic polarization curves of the steel DIN 1.4301 (0.017% S) were measured. In the case of an active 10 pm x 5 pm inclusion, the electrochemical current shows an abrupt increase over a limited potential range (shaded areas). To avoid the dissolution of an inactive 3 pm x 3 pm inclusion in the transpassive range, the measurement was stopped at 1000 mV. Subsequent optical microscopy studies of the same area revealed that the inclusion had been dissolved during the experiment. The SEM pictures indicate the nearly complete dissolution of the oval, active inclusion (Fig. 10, top left), whereas the inactive inclusion of a rounded shape (Fig. 10, bottom) did not dissolve at all.

The evidence from these methods suggests that lower values of diffusion constants are obtained from methods which are sensitive to factors important over longer distances, and so indicate that defects can have a controlling effect in diffusional rates. This is shown clearly in interference optical microscopy studies of methanol adsorbing into crystals of CrAPO-5, where the hexagonal prismatic crystals are found to possess large sectors that are inaccessible to adsorbate molecules. The existence of barriers to molecular adsorbates at the external surfaces of zeolites has also frequently been reported and can be visualised directly by comparative interference microscopy on as-prepared and also surface-etched ZSM-5 crystals. ... 

The four fluorescent taxols 11.3.16-11.3.19 were prepared by Nicolaou and his colleagues 402), and 11.3.18 was found to be the most suitable derivative for optical microscopy studies of the cell.

Mfartures of PPY(MSA)j g and OG were prepared in different molar ratios 1.0 0.5, 1.0 1.0, and 1.0 2.0 between MSA and OG. Here we will restrict our discussion to the last composition. The optical microscopy study of the supramolecular hairy rod PPY(MSA)i o(OG)2,o showed that the material is an optically isotropic fluid above ca. 180° C, forms an optically anisotropic self-...
