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 ...

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 can be defined as the resistance of a fluid to flow. This resistance is caused from the forces of attraction between the fluid molecules. A fluid will only flow if sufficient energy is ...

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 ...

In this article, we will consider what viscosity is, how it is measured and the applications of viscometry in the food and beverage industry. When a force or stress is applied to a fluid, it flows, ...

To meet the expected greenhouse gas/fuel efficiency standards the federal government is in the process of developing, oil companies and engine makers have been busy developing a new standard for ...

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 ...

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 ...

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 ...
