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 ...

Viscosity is one of the standard physical properties used for qualifying many industrial products. Various types of viscometers are available, of which the rotational viscometer is the most efficient ...

(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 ...

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 ...

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 ...

A research team led by MedUni Vienna has shown in a study that purely optical measurements of the viscosity of blood plasma may provide information about the severity and progression of COVID-19. The ...

The 2018 Kilauea eruption provided scientists with an unprecedented opportunity to identify new factors that could help forecast the hazard potential of future eruptions. “The study is very unusual ...

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 ...
