A Simple Method for Fabricating an External Light Extraction Composite Layer with RNS to Improve the Optical Properties of OLEDs.

In this study, we fabricated a random nanostructure (RNS) external light extraction composite layer containing high-refractive-index nanoparticles through a simple and inexpensive solution process and a low-temperature mask-free process. We focused on varying the shape and density of the RNSs and adjusted the concentration of the high-refractive-index nanoparticles to control the optical properties. The RNSs fabricated using a low-temperature mask-free process can use the distance between the nanostructures and various forms to control the diffraction and scattering effects in the visible light wavelength range.

Quality by Design approaches to assessing the robustness of tangential flow filtration for MAb.

Quality by Design (QbD) is a modern approach for quality assurance in pharmaceutical production. This article illustrates a case study of TFF robustness performed for a process characterization of a monoclonal antibody under QbD principles by exploring functional relationships that link the process parameters to quality/process attributes with prior process knowledge, risk assessment, and multivariate experiments. In every case of quality or process attributes, all measured values were in alignment with the allowable specification range, and the developed models were non-significant and had no lack of fit, thus confirming the robustness of the TFF process within the tested ranges of process parameters.
