Texture dynamic behavior

The present work investigates the static and dynamic behaviors of liquid droplets on 14 silicon wafers coated with one of two substrate materials with standard semiconductor industry processes. Wafers 1-10 were textured with an array of squares containing a nanopattem of linear grooves, and wafers 11-14 were unpattemed. Since the patterns were anisotropic, each test was conducted in two directions — parallel and perpendicular to the pattern. These directions could be easily tracked by their relation to the wafer notch. A schematic of the patterned wafers is shown in Fig. 1. 

Dynamic rheometers have been widely used to study the viscoelastic characteristics of liquid, solid, and semi-solid foods. However, to our knowledge, very few studies on the rheological characteristics of potato flesh using dynamic rheometry have been carried out. The dynamic rheological behavior of potato tubers may be helpful to have a quick idea about potato texture and...

In dynamic x-ray diffraction studies reported earlier (17). perpendicular equatorial and meridional arcs with the same d-spacing were observed in drawn fibers. Both pairs of arcs showed different transition temperatures. DSC of annealed samples showed a small endo therm at 120°C which occurred at the same temperature observed for the transition in the BP6L meridional diffraction arc. The endothermic transition of the annealed THF insoluble fraction corresponds to the 160°C transition of the BP6L equatorial diffraction arc. Both fractions exhibit mesophase behavior above the observed thermal transitions, and only a subtle textural change is evident at that temperature under crossed polars, indicating that these thermal transitions are due to trace amounts of crystallization. The BP6Li fraction displays characteristics of the smectic mesophase while the texture and x-ray observations of BP6Ls do not allow conclusive identification of the mesophase (presumably nematic).
