Multiscale Simulations of Phosphatidylinositol Bisphosphate: Understanding Its Biological Role Through Physical Chemistry
… and PtdIns(4,5)P2 - act by changing the physical-chemical properties of the membrane rather than by specific biochemical binding to proteins. We also predict that PtdIns(3,5)P2 and PtdIns(4,5)P2 alter the mechanical of properties in distinct ways due to the larger size and altered charge …

Analysis of scientific argumentation in two physical chemistry classrooms using the POGIL approach
… work considers two implementations of the POGIL physical chemistry curriculum and evaluates the classroom argumentation. The researchers aimed to consider the content of the arguments and dialectical features characteristic of socially constructed arguments (Nielson, 2013). To do this, whole …

The Physical Chemistry Underlying the Assembly and Midpoint Potential Control in a Series of Designed Protein-Maquettes
In nature, oxidoreductase proteins are responsible for many enzymatic processes critical to life. These proteins often rely on the presence of non-proteinaceous cofactors to take part in the enzymatic function. The most common, central to my thesis, is heme B. Depending on the protein environment, …

Removal of metal ions from solution by foam fractionation methods
… separation of solute from liquid solutions. The physical chemistry of a foam-liquid system was investigated including studies of foam density, foam stability and foam drainage, and the counter-current flow of liquid and foam. The experimental results obtained were tested with models proposed for …
