Researchers from UC San Diego have come up with a radically different solution for severe blood loss treatment. In their study, fluids with much higher salt content than conventional saline are combined with viscosity enhancers with the purpose of thickening blood.
The exact mechanism by which Arginine molecules affect protein molecules in solution is unclear. Nonetheless, its benefits increasing solubility and controlling viscosity have spread out its application in biopharma formulations, specially for high concentration antibody solutions.
In our application note, we examine the effect of concentration on the viscosity of dilute solutions of L-Arginine in water and PBS. Additionally, we study the Intrinsic Viscosity of this solutions to better understand molecular size and solubility in dilution.
Whether you work with printed electronics, touch displays, or any of the number of applications working with conductive inks, coatings, paints and pastes, viscosity is one of the key parameters in the development of your process. Over the last few months, RheoSense has released a number of applications related to conductive inks. Our instruments allow for accurate rheological charaterization of these samples between 4°C and 105°C. Check them out!
Even in California, winter can be a bit of a traumatic season. With the sun going down at 5 P.M. we got a bit of a vampire complex and decided to make February our month dedicated to the viscosity of blood and its derivatives. To go with our mood, we also published an application note on the viscosity of plasma and serum. However, this seemed a bit like decaf coffee to us. If you know the RheoSense crew, we love our coffee! Hence, we wanted to look at the real thing!
That's right! You can 3D-print food. This presents a new and very interesting perspective in cooking with opportunities to modify the structure of the goods we eat. Icing, syrups, honey, nutella, dough... there are few limitations and some challenges to this process.
Our viscometers have redefined the way viscosity is measured! With our patented VROC® technology, RheoSense viscometers are able to provide viscosity measurements across a broad spectrum of applications. With our small sample volume requirement, our viscometers have attracted the attention of not only scientists trying to measure true viscosity of Newtonian and non-Newtonian liquids, but also of those looking to measure viscosity of different common fluids.
Every event we go to, we are asked if we have measured the viscosity of countless different common fluids. What is the viscosity of honey? Have you measured motor oil? Was it used oil? What about paints and inks? In this last post of the year, right before the holiday break, we ask you: What would you like us to measure?
You can always check our application library to see what fluids we have already tested:
A few weeks ago, RheoSense sponsored November’s meeting for the Golden Gate Polymer Forum: "Properties and Applications of Synthetic Adhesive Polymers Inspired by Mussels, Wine, Tea, Chocolate and Other Edibles” by Prof. Phillip Messersmith from U.C. Berkeley.
Professor Phillip Messersmith's research is focused on biologically inspired materials. To learn more about Professor Messersmith's work, please check out his website!
Looks like every spider will be shopping this holiday season for a viscometer to fine tune the viscosity of the glue droplets that cover spider webs and strands. Luckily RheoSense made the microVISC™, a portable and battery powered viscometer/rheometer. As Spidey (the little spider living in one of the corners of my backyard) puts it: “I needed a fast, portable and Simply Precise™ instrument. Rheosense had the perfect solution for me. Now my spider webs are stickier than ever!”
