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 ...

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.

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 ...

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 ...

(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 ...

Based on an acoustic viscosity measurement technique, the hermetically sealed VISmart solid-state viscosity sensor is unaffected by vibrations or flow conditions, and needs no calibration. Immersed in ...

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 ...

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 ...

The Battery Experts with Anthony Chalou from Anton Paar explores the physical parameters of electrolyte solutions and their importance during battery manufacturing. Electrolytes are an integral part ...

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 ...
