An Introduction To High Pressure Rheology High pressure rheology explores phenomena that are not accessible at ambient laboratory conditions. Three of the advantages of using a pressure rheometer cell include a controlled environment for volatile fluids, saturating fluids with soluble constituents, and exploring new phase space using a combination of temperature and pressure.
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,…
DetailsOverview Tribology is the study of friction between two interacting surfaces. Traditionally encompassing friction-based studies of lubrication and wear, the applications of this field has expanded into different industries such as food and beverage (e.g: quantify mouthfeel and texture), personal care (e.g: quantify skin-feel), asphalt (e.g: development of warm mix asphalt technologies) and rubbers…
DetailsOverview Rheo-microscopy combines rheological measurements with simultaneous investigation of the material’s microstructure, and how it may evolve in response to external stresses or strain fields. This webinar will showcase the power of rheo-microscopy for an accurate interpretation of rheological data in the context of three case studies, each on a different material and using…
DetailsOverview 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…
DetailsOverview During the formulation and manufacturing of polymeric materials for medical devices, the materials go through multiple stages and undergo many transformations. At each of these stages new additives might be added or the material is exposed to physical factors like heat which impacts the chemical nature of the ingredients. Subsequently, during the final product…
DetailsOverview You will gain insight into the role of chemical characterization in newly modified EU Medical Device Regulations (EU MDR) impacting ISO 10993. This webinar highlights how you can leverage HRMS to overcome characterization challenges.
DetailsSummary 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…
DetailsOverview The viscoelastic properties of polymers play a critical role in the different stages of polymer processing operations, whether it is melting and extrusion or the performance of the final product. On most polymer data sheets, these properties are presented in the form of a melt flow index. However, this simplistic approach is inherently…
DetailsDesigning New Materials for Additive Manufacturing: Vat Photopolymerization Overview 3D printing, or additive manufacturing (AM), provides opportunities to create previously unattainable geometric objects through layer-by-layer fabrication. Novel macromolecular structures and synthetic methods coupled with unique printing methods lead to 3D part generation with micron-scale resolution and tunable to emerging technologies. By tuning polymer structure, printing…
DetailsOverview Have you been tasked with answering any of the following or similar questions? Will our product flow under these conditions? What are the optimal processing conditions? Will this formulation be accepted or rejected by our sensory panel? What is the working time for this adhesive? How strong is the final composite sample? Will…
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…
