Micellar Aggregates of Gemini Surfactants: Monte Carlo Simulation of a Microscopic Model [PDF]

open access: yes, 1997
We propose a "microscopic" model of gemini surfactants in aqueous solution. Carrying out extensive Monte Carlo simulations, we study the variation of the critical micellar concentration (CMC) of these model gemini surfactants with the variation of the (a)

Semisynthetic Hydrophilic Polyals [PDF]

open access: yesBiomacromolecules, 2005
Non-bioadhesive, fully biodegradable soluble polymers would be very instrumental in advanced biomedical applications, such as gene and drug delivery and tissue engineering. However, rational development of such materials is hindered by the complexity of macromolecule interactions with biological milieu.
