Synthesis and Exfoliation of Discotic Zirconium Phosphates to Obtain Colloidal Liquid Crystals

Abstract:
Structural features of the Z-line were examined in negative stained rabbit psoas myofibrils. The data obtained allow to conclude that: 1) the amount of overlap of actin-containing filaments from apposing sarcomeres is about 50 nm; 2) there are five bands of extra density separated by the distances approximately 20 nm across entire Z-line width, and three central of these bands are localized in the actin overlap region; 3) the axial repeating distance between Z-filament attachment sites on thin filament is found to be 17-20 nm. A model for the array of cross-bridges between action-containing filaments in Z-line is presented.

z Scores and Unusual Values
This score indicates how far a value is from the mean in terms of standard deviation. For example, if a data value has a z score of +1, the researcher can infer that the particular data value is one standard deviation above the mean. If another data value...
Electric Field of a Charged Disk
The system's symmetry is in the cylindrical directions across the plane of the charge. As a result, the electric fields created by various surface charge elements nullify each other in the direction parallel to the surface. Thereby, the resulting electric field is perpendicular to the plane. Since the disk is...
