Article Synopsis
- A critical issue in materials science is how to accurately characterize the properties of colloidal inorganic nanocrystals, which often vary in size, density, and molar mass due to their polydisperse nature during synthesis.
- The presence of surfactants used to control these nanoparticles' properties complicates the measurement of their diameter after synthesis and thus affects accurate characterization.
- The Custom Grid method, implemented in UltraScan-III, allows for high-resolution characterization of nanoparticles by simultaneously analyzing two out of three varying parameters (like density, molar mass, and size) by holding one constant.
A method for fitting sedimentation velocity experiments using whole boundary Lamm equation solutions is presented. The method, termed parametrically constrained spectrum analysis (PCSA), provides an optimized approach for simultaneously modeling heterogeneity in size and anisotropy of macromolecular mixtures. The solutions produced by PCSA are particularly useful for modeling polymerizing systems, where a single-valued relationship exists between the molar mass of the growing polymer chain and its corresponding anisotropy.
