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 ...

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 ...

Anton Paar is proud to announce the release of Lovis 2001, a state-of-the-art rolling-ball viscometer, designed for laboratories requiring precise viscosity measurements, especially for low-viscosity ...

Researchers from the Universitat Autònoma de Barcelona and the MATGAS research centre, the Universitá di Roma "La Sapienza" and the Politecnico di Milano have designed a method which indirectly ...

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 ...

Relationship between a measure of structural disorder and viscosity for a polydisperse hard-sphere-like system. The relationship between the structural measure and the viscosity can be collapsed on ...

The thinner in oil is the easier it pumps through the engine, which leads to a fuel economy improvement. We can all understand that, but there's a lot more to oil viscosity than how thick it is. I ...

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 ...
