Extensional Rheology & Analytics of Material Characterization

Extensional Rheology & Analytics of Material Characterization OVERVIEW Extensional flows are important to converging and squeezing flows that occur in polymer processing operations such as injection molding, extrusion, blow molding, film blowing and calendering. Uniaxial extensional flow measurement is particularly useful in polymer characterization because it is the ‘strongest’ flow field one can generate with…

Practical Aspects of Kinetics Determination by Thermal Analysis

Practical Aspects of Kinetics Determination by Thermal Analysis This presentation describes how DSC and TGA are used to obtain kinetic parameters and the relative merits of each approach. Guidelines will be given for the selection of the best approach and insight will be shared regarding the common uses of kinetic parameters specifically for hazard evaluation…

An Introduction to Lifetime Testing by Thermogravimetry

An Introduction to Lifetime Testing by Thermogravimetry Lifetime testing by thermogravimetry (TGA) is a well-established, powerful technique for predicting the long-term aging characteristics of a material in a short experimental time. Multiple techniques and models are presented and compared for lifetime testing, including Modulated TGA™, and a survey of the current ASTM methods and the…

Measuring Thermodynamic Parameters in the Drug Development Process

Measuring Thermodynamic Parameters in the Drug Development Process Is there a benefit to measuring thermodynamic parameters in the drug development process? In this TA Instruments Webinar, Dr. John E. Ladbury discusses Thermodynamic Parameterization of protein-ligand interaction, not only provides quantification of the affinity of an interaction, but also the underlying changes in enthalpy and entropy.…

Gerald Fuller – Interfacial Rheology

Gerald Fuller – Interfacial Rheology OVERVIEW Interfacial rheology dominates the behavior of many complex fluid systems. Whether the system is characterized by a fluid-fluid interface or fluid-air interface, these characteristics influence the behavior of biological systems, oil recovery, personal care products, food and more. Learn about the basic forces that drive interfacial dynamics and stability,…

Thermodynamic Rules To Achieve High Binding Affinity & Selectivity

Thermodynamic Rules To Achieve High Binding Affinity & Selectivity High affinity and selectivity are two essential properties of drug molecules. Since the binding affinity is determined by the sum of enthalpic and entropic contributions, extremely high affinity necessitates optimization of both contributions to binding. An efficient approach requires accurate prediction of the contributions of specific…

Gareth H. McKinley – Rheological Fingerprinting of Complex Fluids

OVERVIEW Large amplitude oscillatory shear (LAOS) is used increasingly as a tool to measure the nonlinear viscoelastic responses of soft solids and complex fluids. For many material systems the common practice of reporting only «viscoelastic moduli» (typically corresponding to the first harmonic Fourier coefficients G’1(w), G»1(w)) is insufficient and/or misleading in describing the nonlinear phenomena.…
