Not many people besides rheologist and scientist think much about viscosity, but it plays a very important roll in geology and geography. Check out this NASA article and next time you look at the landscape you might be thinking about viscosity.
A recent study has been released by brilliant researchers at Penn State. Upon careful research, it has been discovered that bacteria plays a role in viscosity. Solutions where bacteria is highly concentrated, it was observed that there was a decrease in viscosity. Initially thought to be a result of high concentrations, researchers dug deeper.
As a lubricant begins to breakdown it undergoes significant viscosity changes. These viscosity changes can play a critical role in the life and performance of moving parts. For example, knowing when to change the engine oil in a car is straightforward, every 3,000 to 5,000 miles is a good rule of thumb. Going beyond the recommended scheduled oil change runs the risk of critical component failure leading to engine damage. However, what if you don’t have a convenient method, like miles driven, to gauge the health of your lubricant? How will you know when the lubricant begins to breakdown? The solution to this is knowing your viscosity!
We have all read this click bait title many times over.
Yes, we are at the dawn of the autonomous revolution and ultimately, some jobs will be replaced by robots. The good news is that this revolution is going to accelerate science and technology at a rapid pace. The companies and individuals who invest and embrace automation will have a large competitive advantage over those who stick to traditional techniques.
Ok, here’s the scene...An explorer is traipsing through the jungle, visibility is low due to the dense vegetation, he’s chopping away at the vines and plants when suddenly he enters to clearing.

What do we talk about when we talk about viscosity? A series stories of viscosity in life.

This month, one of our partners in Korea, Insung Chromatech, hosted a seminar in Korea's Science Town. Science Town is a well known area in South Korea for the research & development hub of leading institutes and companies.
Unlike height and weight, which people have a good sense about based on common items, viscosity is much harder to describe.
One of the challenges of creating monoclonal antibody (mAb) injectable drugs is optimizing formulation. A good formulation has to have a high concentration of stable mAb’s for high efficacy. There are a variety of factors that can affect stability of these mAb’s, temperature, shear forces, pH, and even concentration. When proteins become, unstable and denature they can increase the viscosity of your formulation. Using a simple modified parallel plate demonstration, we can visualize why denatured proteins increase viscosity.
As marijuana use becomes more mainstream, the use of vaporizer pens or vape pens as a delivery system for THC is steadily increasing in popularity. Vape pens are not your classic bongs as seen in some old school Cheech and Chong movies, but are in fact a high-tech device; a high-tech device where precision and accuracy are critical to performance.
