The Effect of Stability and Surface Charge Distribution on Secretion of Bovine Pancreatic Trypsin Inhibitor From Yeast
… of the BPTI mutants shows that removal of charges results in a drop in the effective number of ionic binding sites, as analyzed by binding of the molecule to a cation exchange column. Removal of the charge on the uncharged face of the molecule results in a dramatic increase in the relative …

Fundamental and applied aspects of contact electrification
… a plane dielectric sample. Measurements of the charge transferred to metal contact spheres, and the two-dimensional dielectric surface charge distribution, have been carried out under controlled conditions. The dissipation processes of air breakdown and bulk condution have been studied. The …

Heavy metal adsorption on iron oxide and iron oxide-coated silica : macroscopic, spectroscopic, and modeling studies
… and well-characterized minerals. Two important surfaces are iron oxide and silica, which are ubiquitous and associated with one another in the environment playing important roles in metal distribution. The objectives of this research are to develop models for predicting speciation and mobility …

Molecular Structure, Diffusion Dynamics and Hydration Energetics of Non-Confined Water and Water at Mineral Surfaces
… structure, dynamics and energetics of water at surfaces and in nano-confined spaces provide greatly increased, atomistically detailed understanding of the effects of surface structure and composition on the structural ordering, hydrogen bond organization, interfacial transport and hydration …

Cellulose Nanocrystals: Size Characterization and Controlled Deposition by Inkjet Printing
… in terms of length, width, and thickness distributions by atomic force microscopy (AFM) and dynamic light scattering. Aqueous CNC suspensions were characterized in terms of shear viscosity with a rheometer. Glass substrates were cleaned with a detergent solution, aqua regia, or a solvent …

NMR Studies of Aqueous-Electrolyte Ion Sorption in Energy Storage Materials
… aqueous electrolytes. However, the impact of charged species including hydronium (H<sub>3</sub>O<sup>+</sup>) and hydroxide (OH<sup>-</sup>) on the ion adsorption and surface charge distribution are poorly understood, hindering the design and optimisation of devices with enhanced performance. …

Protein adsorption on nanostructured silica surfaces
… of globular proteins with nanostructured silica surfaces. It aims to gain a better understanding of the consequences of a high surface curvature and confinement on the adsorption behavior and morphology of the adsorbed protein. The adsorption behavior of lysozyme and 𝛽-lactoglobulin on silica …

Reconstituting APP and BACE in proteoliposomes to characterize lipid requirements for β-secretase activity
… physico-chemical character (fluidity, curvature, surface charge distribution, lateral domain heterogeneity etc.) of the lipid bilayer. These collective membrane properties will influence the activity of embedded membrane proteins. In addition, activity regulation may involve a direct interaction …

Interactions between polyhedral permanent magnets
… objective was to analytically solve the magnetic charge model field equations for arbitrary polyhedral permanent magnets with a relative permeability of unity. This was performed using two unique approaches, leading to two unique but equivalent sets of field solutions, with the first being more …
