Excess thermo acoustical parameters such as excess intermolecular free length (Lf), excess adiabatic compressibility (), excess free volume (Vf), excess enthalpy (H) have been measured for propylene glycol in Hexanol for various mole fractions at 303K temperature through ultrasonic sudy. These results have been explained on the basis of intermolecular interactions between the components in the...

We have proposed composite films composed of a molecular-aligned polymer and liquid crystal (LC) for substrate-free liquid crystal displays with high-contrast images. We successfully controlled the molecular alignment of the LC and formed molecular-aligned LC droplets in the polymer by controlling the fluidity of the LC/monomer mixture and the curing rate of the monomer. key words: substrate-fr...

A standard mixture of 25 short-chain fatty acids was resolved by high-performance liquid chromatography, using an Aminex HPX-87 column. The acids produced in culture media by anaerobic bacteria were analyzed by high-performance liquid chromatography after extraction with ether and reextraction into a small volume of 0.1 N NaOH. The presence of fumaric acid in culture extracts of Peptostreptococ...
