Recent work has demonstrated that organic and mixed organic–inorganic particles can exhibit multiple phase states depending on their chemical composition and on ambient conditions such as relative humidity (RH). To explore the extent to which water uptake varies with particlephase behavior, hygroscopic growth factors (HGFs) of nine laboratory-generated, organic and organic–inorganic aerosol sys...

The need for polymers for high-end applications, coupled with the desire to mimic nature's macromolecular machinery fuels the development of innovative synthetic strategies every year. The recently acquired macromolecular-synthetic tools increase the precision and enable the synthesis of polymers with high control and low dispersity. However, regardless of the specificity, the polymerization be...

We describe a model for the thermodynamics and dynamics of glass-forming liquids in terms of excitations from an ideal glass state to a Gaussian manifold of configurationally excited states. The quantitative fit of this three parameter model to the experimental data on excess entropy and heat capacity shows that "fragile" behavior, indicated by a sharply rising excess heat capacity as the glass...

Ye'elimite occurs in nature and calcium sulfoaluminate cements. The thermodynamic properties of synthetic orthorhombic ye'elimite, Ca4Al6O12SO4, were determined experimentally using low-temperature relaxation calorimetry at higher temperatures differential scanning drop calorimetry. heat capacity, Cp, 480 J/mol/K standard entropy, S°, 487 298 K measured. These values compare well with those cal...
