Supramolecular aggregation of regioregular poly(4-alkyl-2,6-quinoline)s

Article Abstract:

A combination of thermal, microscopic and diffraction methods is used for examining the phase behavior and morphological features of regioregular, n-type semiconducting poly(4-alkyl-2,6-quinoline)s. The presence of nanometer-sized domains is identified in this n-type case, thus implying irrelevance of the excited-state characteristics in ground-state molecular aggregation as well as the general existence of morphological heterogeneity in semiconducting polymers.

Effect of digestion time and alkali addition rate on physical properties of magnetite nanoparticles

Article Abstract:

The study resulted related to the effect of digestion time and alkali addition rate on the size and magnetic properties of precipitated magnetic nanoparticles were observed to increase from 1 to 80 mL/s and the saturation of magnetization of the particles decreases from 60 to 46 emu/g due to the reduced particle size.

Spinodal phase separation of unsteady solid-state binary n-alkane mixtures

Article Abstract:

The phenomenon behind the spinodal phase separation of various unsteady solid-state binary n-alkane mixtures is discussed. The separation is found to lead to the formation of different pure alkane phases.
