Colloidal interactions of thorium
… mobility. This study attempted to determine the interactions of thorium with colloidal humic acid and colloidal silica under various aqueous conditions and organic carbon from Blue point, Muddy, and Rogers Springs. A colloidal distribution study was done in spiked Lake Tahoe and Mono Lake …

The Effect of Switchable Additives on Colloidal Interactions Found in Oil Sands
… dioxide triggered switchable additives affect colloidal interactions found in oil sands, in an effort to identify potential candidates for industrial use. Chemical force spectrometry was used to evaluate adhesion forces present in model oil sand systems. Organic/mineral and mineral/mineral …

STUDY OF COLLOIDAL INTERACTIONS MEDIATED BY BIOMOLECULAR RECOGNITION AND BY ELECTROKINETIC FLOWS.
… PhD thesis focuses on new types of interparticle interactions in colloidal dispersions. In particular, it considers interactions mediated by two different phenomena - biomolecular recognition and electrokinetic flows. The general purpose of this investigation is twofold: while we investigate new …

Probing DNA-Induced Colloidal Interactions and Dynamics with Scanning-Line Optical Tweezers
… materials is directed self-assembly, where the interactions among multiple species of suspended particles are intentionally designed to favor the self-assembly of a specific cluster arrangement or nanostructure. DNA provides a natural tool for directed particle assembly because DNA double helix …

Quantitative analysis of protein liquid-liquid phase separation
… was investigated from the perspective of colloidal interactions. I developed an inverse Monte-Carlo based method to interpret smallangle X-ray scattering data for the purpose of fitting interaction potentials using Derjaguin- Landau-Verwey-Overbeek (DLVO) theory. It was achieved by …

Direct imaging of self-assembly behaviors of colloids: from the microscale plates to the nanoscale cubes
Microscale and nanoscale colloidal particle self-assembly is widely studied to establish the design rules towards ordered structures and used as atomic model systems for phase transition studies such as crystallization and growth. The well-established synthetic library enables the synthesis of …

Stability and precipitation of diverse nanoparticles
… and bioavailability in aquatic environments. The colloidal behavior of organic dispersed CNTs and water dispersed DNDs is investigated. The aggregation behavior of these two colloidal systems is quite different from that of hydrophilic, water soluble functional ized CNTs (F-CNTs). The values of …

A multiscale computational framework for cement paste
… that captures the essential structures and interactions at atomistic (~1 nm), colloidal (~100 nm), and microstructural (~100 [um) length scales. Models are developed and validated through appropriate experiments to ensure realistic configurations and interactions. We begin with the layered …

Development of nanogels from nanoemulsions and investigation of their rheology and stability
… and concentration. Three different regimes of colloidal interactions were observed as a function of SDS concentration. 1) At low SDS concentration (0.5 – 2 times CMC) the counterion shell layer increased the effective volume fraction of the dispersed phase (eff) close to the random jamming, …

PHYSICAL CHEMISTRY OF COLLOIDAL-NANOPARTICLE INTERACTIONS
… by merging the advantageous of inorganic colloidal particles (fixed shape, hard matter) with organic biopolymers (flexible shape, soft matter).In the current dissertation, nanostructured silica suspensions with tunable rheological characteristics were designed via steric and electrostatic …
