Measurement of the Three Elastic Constants and the Shear Viscosity γ1 in a Main-Chain Nematic PolymerK 1, K 2, K 3 and [mgrave]1 have been measured for the first time in a typical main-chain polymer belonging to a polyester series. K 1 is very large compared to conventional nematics...
The unit cell of TaX contains four Ta atoms and four X atoms. Table 1 listed the results of first-principles calculations of structural properties of these materials together with their available theoretical and experimental values34,57,58. The calculated values of lattice constants are in good ...

The Fundamental Nature of Elastic Constants The details of the relationship between bonding and the elastic properties of materials has become more interesting as measurement techniques have improved and computer modeling has become more sophisticated. It has long been understood that elastic constants decr...
An analysis based on the dimensional theory and confirmed by calculations made it possible to conclude that in the first approximation the pressure-difference coefficient depends on the elastic constants through their ratios to the intraocular pressure. A comparison was made with the standard method of...
Elastic constants and conductivity are also closely related30, and enhanced vibrational31,32 and rotational33,34,35 degrees of freedom for the host lattice (typical of more compliant materials) have been shown to correlate with higher conductivities. Lattice-dynamics descriptors have been recently used...
The temperature dependence of the three elastic constants kii (i = 1, 2, 3) and the twist viscosity γ1 of two nematic side chain polyacrylates and one comparable low molecular weight compound have been measured by means of the Freedericksz effect. The change from the low to the ...
The effects of number of sensors and their locations, the magnitude of measurement errors on the accuracy of estimations are investigated. Finally, the standard deviations of estimated material parameters determined numerically and theoretically are compared.doi:10.1080/174159796088027612...
