In rheology, the Deborah number (De) carries a timeless message: everything flows — if you wait long enough. Named after the prophetess Deborah, it stands out as a rare feminine presence in the language of rheology, and a poetic one. The number reminds us that what appears solid and unchanging may, over long enough timescales, soften, yield, and flow.
Valentine’s Day is usually about hearts, flowers, and sweet messages, but this year, we found romance somewhere unexpected: inside a rheometer. With two iconic chocolates as our leading characters, milk chocolate and milk chocolate wrapped in a white crème embrace, we discovered that chocolate has a lot to teach us about love, chemistry, and how relationships behave under heat, pressure, and time.
Developing high-performance materials for demanding applications requires predicting their behavior over a wide range of time scales. Rheology and DMA are powerful tools to understand and predict viscoelastic behavior, including how materials will respond to sudden forces or years of continuous use.
In collaboration with Neil Cunningham, Founder of The Centre for Industrial Rheology, we’re excited to share his expert perspective on the evolving role of rheology in formulation science.
Grab your favorite mug and get ready for a caffeinated clash of titans! We all know that coffees produced in different regions are distinct; like wine, the taste will vary with soil, climate, and altitude. Some of our lab members are partial to the distinct flavors from Colombia and Brazil when it comes to their cups of coffee.
Innovation in materials science is a continuous pursuit, driven by the demand for lighter, stronger, more durable, and more reliable components. This is especially critical in the aerospace and defense industries, where materials must perform reliably under extreme conditions—including intense mechanical stress, wide temperature fluctuations, and long-term environmental exposure.
In battery manufacturing, quality starts with the slurry. For QA/QC professionals, ensuring the consistency and performance of electrode slurries is not just a checkpoint — it’s a quality control imperative. Slurry quality directly impacts electrode uniformity, adhesion, and ultimately, battery performance and lifespan.
Summer is all about sunshine, pool days, and of course — sunscreen. But while most people are focused on SPF and water resistance, we’re here to talk about something just as important (and way more fun if you’re a science nerd): rheology.
As lithium-ion battery technology evolves, reducing production costs has become a top priority for manufacturers and researchers alike. Lower costs not only make batteries more accessible for consumer electronics and electric vehicles but also enhance the viability of renewable energy storage solutions like solar and wind.
Battery slurry formulation and testing is a complex challenge that sits at the heart of lithium-ion battery performance. From slurry mixing to electrode coating, understanding the flow and structural behavior of slurries is critical. For battery scientists seeking precise, reliable characterization tools, rheometers are indispensable. TA Instruments offers two powerful solutions tailored to battery slurry research: the Discovery Core Rheometer and the Discovery Hybrid Rheometer.
In the world of paints, inks and coatings, a single formulation error can make the difference between a flawless finish and a costly mistake. Rheology is the unsung hero that transforms coatings from a simple mixture into a precisely engineered material that meets the most demanding performance requirements.
Coffee lovers know that the grind size and roast degree of coffee beans can significantly impact the flavor and texture of their favorite beverage. But did you know that these factors also affect the rheological properties of coffee powders?
