Introducing the new TAM IV & TAM IV-48 Microcalorimeters The new TAM IV is the world’s most sensitive, stable, and flexible microcalorimeter system. It is completely modular and combines the highest heat flow sensitivity with unmatched long-term temperature stability to measure processes that are undetectable by other techniques.
DetailsThe Role of Interfacial Elasticity on the Rheological Behavior of Polymer Blends: João Maia, Ph.D. The Role of Interfacial Elasticity on the Rheological Behavior of Polymer Blends Polymer blends are commonly used to generate materials with a desired combination of performance properties and cost. Most polymer blends are compatibilized to promote stability of the otherwise immiscible…
DetailsNeil Cunningham: Essential tools for the new Rheologist. What is rheology and how can you use it to practically describe the flow and deformation of structured fluids and soft solids? Neil Cunningham will provide an accessible introduction to key rheological behaviours that will enhance your tool kit for understanding these important product characteristics. He will answer…
DetailsAdvanced Rheological Measurements Of Polymers & Rubber Compounds With the ever increasing market demand for rubber products, those in compounding and manufacturing are tasked with the challenge of increasing output without sacrificing efficiencies. This naturally increases the requirements of processes such as mixing, extruding, and injection molding in the rubber industry. Many factors…
DetailsIn Search of Calorimetric Answers to Events In Self Assemblies In this TA Webinar, Professor Nand Kishore discusses how to best discover and interpret protein folding, ligand binding, aggregation and molecular partitioning in self assemblies. Isothermal titration (ITC) and differential scanning calorimetry (DSC) are powerful tools for thermodynamic characterization of protein folding intermediates, drug-protein…
DetailsExtensional Rheology in Polymer Processing Extensional flows dominate many polymer processes, including blow molding, film blowing, fiber spinning, thermoforming and many others. The rheology of polymeric materials under extensional flows can differ significantly from shear flows and it is important to understand this in order to optimize both materials and processes. In this webinar, we…
DetailsAn Introduction to Tribo-Rheometry: Quantifying Friction Tribology complements rheology, providing information on solid-solid interactions that adds insight to the bulk fluid measurements of rheology. Tribology is especially concerned with quantifying the coefficient of friction as a function of sliding speed and load force, under dry or lubricated conditions. This provides useful information about lubrication, wear,…
DetailsRheo-Microscopy: Bridging Rheology, Microstructure & Dynamics The combination of optical microscopy with rheological tests enables direct observation of material structure under shear deformation. This provides critical information that can help understand, predict, and tune the material response under processing, storage, or end-use conditions.
DetailsMorphology Of Complex Nanoparticle Mixtures The performance of new materials and devices depend heavily on morphological considerations: degree of crystallinity, conformation of amorphous species, and relative organization of one species with respect to another, characteristics which can be determined by thermal analysis. These considerations are important for functional materials such as photovoltaics and MEMS devices,…
DetailsExtensional 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 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 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…
