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…
DetailsPractical 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…
DetailsAn 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…
DetailsUses of Isothermal Microcalorimetry in Urology
Uses of Isothermal Microcalorimetry in Urology In this TA Instruments sponsored webinar, Dr. Olivier Braissant discusses the process of detecting and monitoring biological processes with isothermal calorimetry. This has been shown to be an accurate analytical technique and is proportional to the rate at which a given chemical or physical process takes place.
DetailsPlasma Protein Calorimetry For Clinical Diagnostics
Plasma Protein Calorimetry For Clinical Diagnostics In this TA Instruments sponsored webinar, Dr. Nichola Garbett discusses the emerging technique of using high sensitivity DSC analysis of blood plasma for plasma proteome research, and as a clinical diagnostic tool.
DetailsMeasuring 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.…
DetailsGerald 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,…
DetailsThermodynamic 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…
DetailsGareth 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.…
DetailsJan Vermant – Orthogonal Superposition Rheology
Jan Vermant – Orthogonal Superposition Rheology OVERVIEW Superposition flows in rheology are powerful methods to understand non-linear and anisotropic viscoelasticity. Parallel Superposition experiments have been historically simple to perform, but are difficult to understand and do not provide all of the desired information. Recent developments have made Orthogonal Superposition more simple to perform, allowing…
