Triisopropyl silane (TIPS) is an organosilicon compound with the formula (i-Pr) 3 SiH (i-Pr = isopropyl). This colorless liquid is used as a scavenger in peptide synthesis . It can also act as a mild reducing agent.
In modern chemical process industries, high-shear mixing technology has been used to create many novel suspensions. Suspensions are unstable from a thermodynamic point of view but can be kinetically stable over a longer period of time, which in turn can determine a suspension's shelf life.
A static mixer is a device for the continuous mixing of fluid materials, without moving components. [1] Normally the fluids to be mixed are liquid, but static mixers can also be used to mix gas streams, disperse gas into liquid or blend immiscible liquids.
Fluid undergoes shear when one area of fluid travels with a different velocity relative to an adjacent area. A high-shear mixer uses a rotating impeller or high-speed rotor, or a series of such impellers or inline rotors, usually powered by an electric motor, to "work" the fluid, creating flow and shear.
Mixing of liquids occurs frequently in process engineering. The nature of liquids to blend determines the equipment used. Single-phase blending tends to involve low-shear, high-flow mixers to cause liquid engulfment, while multi-phase mixing generally requires the use of high-shear, low-flow mixers to create droplets of one liquid in laminar, turbulent or transitional flow regimes, depending ...
Many times, he said, the doctors appeared indifferent to his son’s condition. “They just treat them and get them out of there,” he said. “That was hard for me…it tore me up. You just can’t explain how you see your son lying there and almost dying. There’s a couple times that I was really upset. I was mad at my son, really upset.
