Dynamic Mechanical Analysis (DMA) is a thermal analysis technique used to measure the mechanical properties of materials as they are deformed under periodic stress. DMA is commonly used to determine the viscoelastic behavior of polymers, composites, and other materials.
DetailsIn autumn of 2021, the 26th UN Climate Change Conference of the Parties (COP 26) met in Glasgow to work out agreements to curb greenhouse gas emissions and prevent additional climate change. COP 26 built upon the Paris Agreement to limit global warming below 2-degrees Celsius by achieving net zero carbon dioxide (CO2) emissions. These two agreements will shape how governments and industries work together to reduce climate change over the next decade.
DetailsWhether researchers are optimizing the texture of yogurt or studying adhesives’ curing, rheometry helps us understand materials and predict their behavior. Rheometry measures the amount of deformation a material or liquid undergoes when a force is applied. The combination of stress, strain and shear behavior forms the basis of rheology, the science of the deformation of materials.
DetailsOn holiday tables across the world, an unexpected unsung hero can make or break the meal: gravy. The seemingly simple condiment adds a dash of flavor to the star roast, livens up potatoes, and can rescue even the driest turkey that may accidentally make its way to the table.
DetailsSummer’s blue skies and warm temperatures beckon us to the beach. After all, summer is synonymous with fun in the sun, surf, and sand. And what is a day in the sand without building a sandcastle? While rising tides can be every sandcastle builder’s enemy, the ocean is also their greatest ally. That’s because damp sand sticks together, allowing sandcastle magic. Dry, powdery sand may feel nice but it’s no friend of castle building and a large part of that is down to cohesion. Quick tests of moist and dry sand showed a 10x difference in cohesion!
DetailsConsumer interest and sustainability goals are driving soaring demand for electric vehicles. The U.S. aims for electric vehicle sales to reach 50% of the total market by 2030, yet 99% of the raw and component materials for EV batteries are produced externally.1, 2 Sourcing foreign-made materials and batteries has already created challenges in the industry. Russia’s invasion of Ukraine led to market instability that caused the price of nickel, a key battery material, to skyrocket in March 2022.
DetailsThe recent release of our 2022 Environmental, Social, and Governance (ESG) report demonstrates a continued commitment to leaving the world better than we found it. The pursuit of the goals outlined in this report remains a top priority for our company and this year’s edition reflects both our current focus areas and future ambitions.
DetailsI love a good experiment in the kitchen, especially when it involves baking and desserts. In celebration of Pi Day, let’s take science and experiments into the kitchen with pie dough and fillings…and a rheometer.
DetailsWill my paint coat the wall or drip off? Will my topical pharmaceutical spread on skin or form clumps? Rheology answers vital questions to inform how we create and interact with materials on a daily basis.
DetailsPharmaceutical development is highly regulated, and for good reason. Potential new products must be rigorously tested to ensure their safety, purity, and performance are acceptable before coming to market. For topical creams, regulations uphold stability lifetime parameters and require identification of any impurities before products reach consumers.
DetailsFrom shiny cars to streak-free walls, we demand a lot from our coatings and paints. A high-quality paint not only needs dazzling color, but also must offer the right material properties for a smooth application and drying process. Consistency is crucial: too thin and the paint will run and drip; too thick and it will clump and not dry evenly. Spray paints and coatings also need to be applied smoothly without clogging the spray device.
DetailsHydrogels are three-dimensional porous strctures that can absorb large amounts of water. They can be made up of polymers, protein, peptides, colloids, surfactants, or lipids.1 Hydrogels’ ability to uptake large amounts of water is useful for many biological applications, including drug delivery and tissue engineering. Since a hydrogels’ properties change as it absorbs water, scientists must accurately characterize its behavior at different saturation amounts and in varying conditions.
