Viscosity of concentrated mRNA solutions: Implications for downstream processing

open access: yesBiotechnology Progress, EarlyView.
Abstract Messenger RNA (mRNA) therapeutics can be used to protect against infectious disease and for the treatment of cancers and genetic disorders. In order to obtain the desired therapeutic dosage, it is necessary to concentrate the mRNA to levels where the viscosity of the mRNA solutions can become significant.

From Confusion to Clarity: A Multi‐Stage Process Framework for Understanding Consumer Confusion

open access: yesJournal of Consumer Behaviour, EarlyView.
ABSTRACT This paper reconceptualizes consumer confusion as a multi‐stage temporal process rather than a static outcome, addressing theoretical fragmentation in existing antecedent‐consequence models. By integrating cognitive appraisal, contextual amplification, and adaptive coping within a unified framework, we explain how confusion unfolds rather than

Reynolds number influences in aeronautics

open access: yes, 1993
Reynolds number, a measure of the ratio of inertia to viscous forces, is a fundamental similarity parameter for fluid flows and therefore, would be expected to have a major influence in aerodynamics and aeronautics.

High‐Temperature Heat Pump Test Bench with n‐Butane (R‐600) Generating Steam

open access: yesChemie Ingenieur Technik, EarlyView.
This work involves building a test bench for a high‐temperature heat pump (HTHP) and analyzing the measurements. The focus is on steam generation using an HTHP to decarbonize process steam demand. The findings indicate that stable steam generation is possible, providing a higher heat transfer coefficient in the heat pump's condenser.

Automated Process Optimization in a Novel Triple Shaft Mixer with Adaptive Mixing Modes

open access: yesChemie Ingenieur Technik, EarlyView.
A novel multi‐purpose mixer with adjustable blade angle and a coaxial stirrer is developed, providing three degrees of freedom. An optimization strategy is integrated to autonomously identify optimal operating conditions through automated tests. The current draw of the main stirrer serves as the optimization criterion, while stirrer speeds, directions,

The Filament Extension Atomization Process for Powder Production of Elastic Fluids

open access: yesChemie Ingenieur Technik, EarlyView.
Filament extension atomization is a promising technique for spraying a wide range of materials, enabling narrow droplet size distributions. This study examines the behavior of various fluids and suspensions to define application limits and identify optimal operating conditions.
