Capillary breakup rheometry is an experimental technique used to assess the extensional rheological response of low viscous fluids. Unlike most shear and extensional rheometers, this technique does not involve active stretch or measurement of stress or strain but exploits only surface tension to create a uniaxial extensional flow.
Capillary rheometers are especially advantageous for characterization of therapeutic protein solutions since it determines the ability to be syringed. [6] Additionally, there is an inverse relationship between the rheometry and solution stability, as well as thermodynamic interactions. Rotational geometries of different types of shearing rheometers
Rheometry (from Greek ῥέος (rheos) 'stream') generically refers to the experimental techniques used to determine the rheological properties of materials, [1] that is the qualitative and quantitative relationships between stresses and strains and their derivatives.
The website expanded into nine more U.S. cities in 2000, four in 2001 and 2002, and 14 in 2003. On August 1, 2004, Craigslist began charging $25 to post job openings on the New York and Los Angeles pages. On the same day, a new section called "Gigs" was added, where low-cost and unpaid jobs can be posted for free.
As firefighters make some progress in the battle against a series of devastating wildfires in the Los Angeles area, the numbers thus far are jarring: At least 24 people have been killed, more than ...
The bubble pressure method makes use of this bubble pressure which is higher than in the surrounding environment (water). A gas stream is pumped into a capillary that is immersed in a fluid. The resulting bubble at the end of the capillary tip continually becomes bigger in surface; thereby, the bubble radius is decreasing.
In chemical analysis, capillary electrochromatography (CEC) is a chromatographic technique in which the mobile phase is driven through the chromatographic bed by electro-osmosis. [1] [2] Capillary electrochromatography is a combination of two analytical techniques, high-performance liquid chromatography and capillary electrophoresis.
Held hostage in fear for 15 months by Hamas, 24-year-old Romi Gonen, 31-year-old Doron Steinbrecher and 28-year-old Emily Damari were finally on their way to being back in the eager arms of their ...
