Poster In-Operando Isothermal Microcalorimetry to Accelerate Screening of New Battery Chemistries Authors: Jeremy May, Hang Lau Technology: Battery Cycler Microcalorimeter Solution Abstract Screening new cell chemistries using traditional electrochemical methods is a time prohibitive process that significantly slows the pace of research. These methods involve cycling the cell until signs of degradation or sufficient capacity…
TAM III Microcalorimeter instruments will enter their end-of-life at the end of 2023. Repair and maintenance will be performed with “best effort” after 2023, subject to the availability of parts. In the attempt to facilitate a smooth transition to the TAM IV Microcalorimeter series, TA is offering a trade-in program with exclusive packages for our valued customers.
This note investigates the degradation kinetics of virgin and recycled polyethylene terephthalate fibers used for 3D printing through TGA, finding similar lifetime predictions for the samples studied.
DSC step annealing is used to study the fine molecular structure of poly(vinylidene fluoride) (PVDF) homopolymers and copolymers. The melting pattern, obtained after step annealing, is a characteristic “fingerprint” for small variations in structure. This “fingerprint” detects variations in the polymerization process, the molecular weight of the polymer, the fraction and the nature of the co-monomer.
Differential scanning calorimetry (DSC) provides a rapid method for determining polymer crystallinity based on the heat required to melt the polymer.
This webinar will cover the essential material characterization techniques that today’s labs need to adopt to develop the batteries of tomorrow.
Materials such as polymers exhibit viscoelastic behavior which is directly related to molecular structure and formulation differences. To accurately evaluate the relationships between molecular structure and viscoelastic behavior requires that experiments, such as rheological measurements, be conducted in regions where the viscoelastic properties observed are independent of imposed stress or strain levels. That is, experiments must be conducted in the linear viscoelastic region.
The viscoelasticity and spreadability properties of cream cheeses can be quantitatively evaluated using TA Instruments Discovery Hybrid Rheometer.
This eBook showcases the various tools accessible to R&D and QA/QC environments for proactive characterization and troubleshooting of polymer materials.
This note will describe the linear viscoelastic region (LVR) and how to determine the LVR in oscillatory experiments for the purpose of obtaining quality data. All aspects of the LVR discussed in this note are general to viscoelastic samples, including (but in no way limited to) polymers, foods, gels, creams, pastes, slurries, emulsions, and inks.
The purpose of this study is to characterize three phase change materials (PCMs) – one paraffin wax and two beeswaxes. PCMs are widely used for thermal energy storage and thermal management due to their high latent heat storage ability.
Ash testing is a common technique used to determine the composition of materials. By heating a sample to high temperature in air all organic substances will pyrolyze leaving behind only inert and inorganic substances. This residue is then weighed to determine its weight percentage in the original material.
