Getting the Rheology Right for Generic Topical Pharma Submissions
Summary For any generic pharmaceutical developer submitting a new drug application, the process of demonstrating the equivalence of a topical pharmaceutical to a reference listed drug can be a grueling process. Not least of the challenges facing regulatory affairs personnel is navigating the often-daunting landscape of rheological measurements. Agencies such as the FDA and EMA…
Comprehensive Rheological Characterization to Optimize Electrode Manufacturing
Summary Electrode manufacturing for lithium-ion batteries is a complex, multistep process that requires comprehensive material characterization to ensure quality and consistency in the final electrodes. Electrode processing involves combining active materials with binders and conductive additives to form a coating on the current collector, either as a slurry or dry coating. The mixing and coating…

Strategies for Rheological Evaluation of Adhesives
Overview Adhesives are widely used across a broad range of industries and are a regular part of consumers’ daily lives. A quantitative understanding of the performance of such materials, such as adhesion, cohesion, tack, and peel performance is important for quality control and guiding formulators. Rheology is a powerful tool that provides direct measurement…
Rheology of Coatings and Inks
Rheology of Coatings and Inks Coatings and inks are two of the most common structured fluids that are characterized on rotational rheometers. Rheometers offer experimentalists many opportunities to perform selected tests that can reveal information about the properties of the fluids and allow one to predict the processability of these systems. Of particular interest are…
Catalysis R&D with High Pressure Thermogravimetry – Instruments and Applications
Overview Catalytic reactions are of tremendous commercial importance. Over 90% of all chemicals worldwide are manufactured with the aid of solid catalysts. Developing improved catalysts and optimizing the reaction conditions are key for improving commercial and ecological efficiency of catalytic processes. High-pressure thermogravimetric analysis (HP-TGA) allows investigating reactions of a catalyst with the gas…
Melt Viscosity Measurements at High Temperatures
Overview Maintaining the optimum viscosity of a molten material is key for efficiency and product quality of many industrial processes. Processing of melts at high temperatures is the basis for classical or additive manufacturing of many materials like glasses or metals. Molten slag or ash viscosity is essential for economically operating industrial gasification processes…
