Every fall, we head to pumpkin patches searching for the perfect pumpkin. Some people pick the classic orange pumpkin. Others are drawn to the elegant white varieties.
As a rheologist, I couldn’t resist putting pumpkins to the test.
Thermal analysis is a branch of material science that studies how a material’s properties change with temperature. From safe medicines to durable airplanes, countless products are made possible through thermal analysis. Understanding a material’s behavior under different temperatures is crucial for the successful design, processing, end use, and recyclability of completed products.
마지막으로 베이글에 크림치즈를 바를 때, 바르는 게 얼마나 쉬웠는지(혹은 어려웠는지) 기억하셨나요? 샐러드 드레싱을 흔들어 분리된 기름과 식초를 다시 섞으시나요?
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.
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.
Powders are a big part of everyday life, from baking and laundry to cosmetics and pharmaceuticals. Understanding powder rheology—how powders flow and deform—is crucial for optimizing their use in various applications. This knowledge helps industries maintain consistency and product quality.
Rheology is a notoriously complex field, combining mathematics and physics to characterize materials. For inexperienced users, rheology can seem like a massive challenge. Luckily, new technology simplifies rheology down to its core so you can get essential measurements without difficult training, measurements, or calculations.
Our world is brimming with viscoelastic materials: The dough you knead before baking a fresh loaf, the Silly Putty your toddler slaps against the wall, the rubber gaskets that create an airtight seal on an airplane door. Testing those materials by applying controlled deformations (strains) or forces (stresses) at various timescales, temperatures, and/or humidities allows for the optimization of properties and ensures durability and safety.
저는 주방에서 멋진 실험을 하는 게 좋아요. 특히 베이킹과 디저트가 관련된 실험을요. 파이 데이를 기념하여, 주방에서 파이 반죽과 필링… 그리고 레오미터를 활용해서 과학을 이용한 실험을 해 보겠습니다.
연구원이 요구르트의 질감을 최적화하거나 접착제의 경화를 연구할 때, 레오메트리를 통해 재료를 이해하고 그 거동을 파악할 수 있습니다. 레오메트리는 힘이 가해질 때 재료나 액체가 겪는 변형의 정도를 측정합니다. 변형력과 변형률, 전단거동의 조합은 재료 변형에 대한 과학인 레올로지의 기초를 구축합니다.
