A New Computational Model to Augment the Design of Microfluidic Separations: Electric Field Assisted, Hydrodynamic Chromatography
… model to simulate the microfluidic separation of like-charged particles in a continuous flow environment. By accomplishing this task the model can be used to optimize future fractionations by tailoring the process parameters to the properties of the target particles. The primary goal of this …

Counterion Behavior in Biopolymers
Counterion behavior controls interactions between charged surfaces in aqueous environments, and can cause attraction between like charged objects. Mean field approaches to describing counterion behavior, such as the Poisson-Boltzmann formalism and Manning condensation theory, predict that charged …

Novel methods for fabrication of non-close-packed structures through colloidal self-assembly
… most colloidal systems of interest are strongly charged. Reducing the electrostatic potential of a system may create only unstable structures without long-range order. In this thesis, electrostatic interaction between strongly charged particles is exploited to make novel structures. It is shown …

DYNAMICS AND COMPACTION OF CONGESTED AND/OR CONFINED DNA
… found indicating circular DNA molecules behave like spherical particles in an entangled system. In the second part, the effects of the like-charged proteins, bovine serum albumin (BSA) and hemoglobin, on the conformation and compaction of single DNA molecule confined in rectangular nanochannels …

Structural properties and phase behavior in colloidal suspensions
… in a system of silica microspheres and highly charged polystyrene nanoparticles. Computer simulations are employed to determine the effective microsphere– microsphere potential induced by the nanoparticles. From these simulations I am also able to determine the degree of nanoparticle adsorption …

Nanoparticle Engineering of Colloidal Suspension Behavior
We investigate the effects of highly charged nanoparticles on the phase behavior, structure, and assembly of colloidal microsphere suspensions. Specifically, by selectively tuning the electrostatic interactions between silica microspheres and polystyrene nanoparticles, we study the behavior of four …

Self -Assembly Between Biomacromolecules and Lipids
… (002) polar planes parallel to the negatively charged sugar-phosphate DNA backbone, which indicates that molecular details of the DNA molecule are imprinted onto the inorganic crystal structure. The resultant nanorods have (002) planes tilted by ∼60° with respect to the rod axis, in …

Mechanistic Studies of Salt Effects on Bimolecular Electron-Transfer Reactions of Pentaamine Ruthenium Pyridyl Complexes Studied by 19F NMR Line-Broadening and T2 Spin-Echo Techniques
… salts increased the rate of ET between the like-charged redox reactants in good quantitative agreement with the quantitative predictions of the Debye-Huckle-Bronsted theory of ion atmosphere charge screening effects, but the other halides exhibited progressively-increasing, non-linear upward …
