Structure and osmotic pressure of ionic microgel dispersions.

The Journal of chemical physics

Hedrick MM, Chung JK, Denton AR.
PMID: 25612730
J Chem Phys. 2015 Jan 21;142(3):034904. doi: 10.1063/1.4905574.

We investigate structural and thermodynamic properties of aqueous dispersions of ionic microgels--soft colloidal gel particles that exhibit unusual phase behavior. Starting from a coarse-grained model of microgel macroions as charged spheres that are permeable to microions, we perform simulations...

Behav Ecol Sociobiol. 2016 Nov;70(11):1941-1947. doi: 10.1007/s00265-016-2200-5. Epub 2016 Sep 09.

Among-individual differences in behavior are now a widely studied research-focus within the field of behavioral ecology. Furthermore, elements of an animal's internal state, such as energy or fat reserves, and infection status can have large impacts on behaviors. Despite...
