食品飲料產業的品質控制只有借助流變學才能實現。
你上次在百吉餅上塗抹奶油乳酪時,有沒有註意到塗抹起來是容易還是困難?你平常會搖晃沙拉醬來重新混合分離的油和醋嗎?

點膠與流動特性對於多種電子製造技術及材料而言至關重要。從錫膏與黏著劑的精密塗佈,到軟性電子與積層製造技術的創新發展,流變學在提升製程適應性、產品品質及製造一致性方面,皆扮演著關鍵角色。
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.
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.
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.
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?
During the Lunar New Year, sky lanterns are released to symbolize the letting go of the past year’s troubles and welcoming new beginnings. The sky lantern tradition is thousands of years old, spreading from Buddhist Monks in the 2nd Century to modern festivals in China, South Korea, Japan, and Taiwan.
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.
If you’re working with materials that can be flowed, for example within pharmaceutical, food, cosmetics, or petrochemical industries, it’s likely that there is a viscometer in the laboratory that is the go-to instrument for formulation testing or QA purposes. However, does this viscometer give you the whole picture and fully meet all your needs?
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.
