TL;DR: In this paper, a recently established synthetic boundary crystallization ultracentrifugation method was applied to stabilized inorganic nanoparticles, showing the quantum size effect was chosen allowing both independent access to particle size via UV-vis absorption measurements and elaboration of the influence of different stabilizer molecules on the CdS particle size distributions.

TL;DR: Sedimentation equilibrium methods which are able to establish a solubility gradient for inorganic species in an ultracentrifugal field are presented in this article, however, in addition to the formation of a density or an equilibrium gradient, physicochemical parameters such as the pH or the solvent quality are varied throughout the solution column if appropriate high-density or high-molar mass solutes are chosen or a mixture of solvents with different density is applied.

TL;DR: In this article, the synthetic boundary cells were applied for carrying out inorganic nucleation reactions inside the analytical ultracentrifuge and the particle size distribution can be determined via the experimentally accessible sedimentation coefficients reflecting the growth process of the colloidal system.

TL;DR: In this article, a fiber-based UV-Vis detector was used for the simultaneous detection of a large number of wavelengths in the range 200-800 nm, also with non-integer values.
