ΕΙΣΑΓΩΓΗ ΚΑΙ ΜΕΛΕΤΗ ΜΙΑΣ ΝΕΑΣ ΚΡΙΣΙΜΗΣ ΣΥΓΚΕΝΤΡΩΣΗΣ ΣΤΗ ΠΕΡΙΟΧΗ ΤΩΝ ΑΡΑΙΩΝ ΜΑΚΡΟΜΟΡΙΑΚΩΝ ΔΙΑΛΥΜΑΤΩΝ
… THE INFLUENCES OF THE TEMPERATURE AND OF THE HYDRODYNAMIC VOLUME OF THE POLYMERS ON THE CRITICAL CONCENTRATIONS ARE ALSO PRESENTED.

Local Viscosity and Environment on the Nanometer Scale
… anisotropy provide the information on the hydrodynamic volume and local viscosity near the probe. Instead, the fluorescence lifetime does the local environment near the probe such as pH, temperature and polarity of the medium. Based on these fluorescence measurements, it was shown that the …

Solution History Effects and Crystal Phase Transformation in Polybutene-1 and Domain Morphology in Polyurethanes
… the solution's intrinsic viscosity show that the hydrodynamic volume of a PB-1 molecule in solution varies considerably with the solution's thermal history, lending support to the idea of retention of helices in solution. The tetragonal (--->) twinned hexagonal crystal phase transformation …

Supramolecular Assemblies: Dendrimers, Linear Arrays, and Polypseudorotaxanes
… corroborated the presence of aggregates of large hydrodynamic volume at high concentrations. The solid state samples of the supramolecular polymers, prepared by freeze-drying, were analyzed by DSC and optical microscopy and shown to be distinct from the starting materials and the cyclic dimer. …

Self-Assemblies Driven by the Hydrophobic Effect
<p>Water is a simple molecule but is an essential part of life. One key aspect of the properties of water is the hydrophobic effect, and whilst there is an appreciation of this phenomenon at the macro-scale (raindrops falling off leaves) and the micro-scale (the structure of cellular systems), a …

Synthesis and Characterization of Wholly Aromatic Semicrystalline Polyimides Based Upon Bis(4-Aminophenoxy) Benzenes
… amic acid stage was successful by employing hydrodynamic volume calibrated, viscosity detector size exclusion chromatography (SEC). The experimental values were found to be within the targeted <M<sub>n</sub>> range of 20-30,000 g/mole. Polyimide powders derived from these ether diamines were …
