I was kind of shocked and amazed by a recent publication in NanoLetters. It seems that viscosity measurements are still difficult. In my ignorance, I had assumed that this was a solved problem. And, ...

Viscosity is a key property of fluids, influencing diffusion, mobility and quite a few other features. There are many methods for measuring macroscopic viscosity, but determining microscopic viscosity ...

Viscometers are used by the food industry to ensure the consistency and quality of liquid foods. Zwick Roell claims its new tester provides what the company claims is an economical alternative to ...

Pharmaceutical companies have increasingly focused on developing high-concentration protein therapeutics that enable patients to treat themselves at home by self injection. However, the formulation of ...

Sound waves can measure viscosity on the fly. Though viscosity is the degree to which a fluid resists flow, it is more specifically a measure of a fluid's molecular friction. It can be a useful ...

Viscosity changes with temperature, and it is recommended to use calibration oils certified at the specific temperature for optimal viscometer performance. Image Credit: Paul N. Gardner Company, Inc.

(Nanowerk Spotlight) In medical applications, artificial micro/nanorobots have gained a lot of attention over the last decade due to their promise to behave as ingestible vehicles of drug delivery to ...

Discover Lovis 2001, a one-of-a-kind rolling-ball microviscometer that operates on Hoeppler's falling ball principle. This falling ball viscometer has an adjustable measurement angle, which ensures ...

Researchers have designed a method which indirectly measures the viscosity of glass - something that required unfeasible observation times at human scale - based on its elastic properties. The results ...

Blood viscosity is a measurement of the thickness and stickiness of an individual’s blood. It is a direct measure of the ability of blood to flow through the blood vessels. It determines how much ...
