In chemistry, a suspension is a heterogeneous mixture of a fluid that contains solid particles sufficiently large for sedimentation. The particles may be visible to the naked eye , usually must be larger than one micrometer , and will eventually settle , although the mixture is only classified as a suspension when and while the particles have ...
The suspension of X is denoted by SX [1] or susp(X). [2]: 76 There is a variation of the suspension for pointed space, which is called the reduced suspension and denoted by ΣX. The "usual" suspension SX is sometimes called the unreduced suspension, unbased suspension, or free suspension of X, to distinguish it from ΣX.
Some of the first suspension structures were bridges. The first iron chain suspension bridge in the Western world was the Jacob's Creek Bridge (1801) in Westmoreland County, Pennsylvania, designed by inventor James Finley. [1] The Golden Gate Bridge in San Francisco, California, is another example of a suspension structure. Much like the ...
Oxide dispersion-strengthened alloy (ODS) is an example of oxide particle dispersion into a metal medium, which improves the high temperature tolerance of the material. Therefore these alloys have several applications in the nuclear energy industry, where materials must withstand extremely high temperatures to maintain operation.
An inexpensive, non-toxic example of a non-Newtonian fluid is a suspension of starch (e.g., cornstarch/cornflour) in water, sometimes called "oobleck", "ooze", or "magic mud" (1 part of water to 1.5–2 parts of corn starch). [22] [23] [24] The name "oobleck" is derived from the Dr. Seuss book Bartholomew and the Oobleck. [22]
For example, the same techniques used to model ideal gases can be applied to model the behavior of a hard sphere colloidal suspension. Phase transitions in colloidal suspensions can be studied in real time using optical techniques, [ 36 ] and are analogous to phase transitions in liquids.
It all depends on the state laws and the reason behind the suspension. South Carolina is one example of a state where you have to pay a $100 reinstatement fee and satisfy all the requirements to ...
If suspension is externally controlled, then it is a semi-active or active suspension — the suspension is reacting to signals from an electronic controller. For example, a hydropneumatic Citroën will "know" how far off the ground the car is supposed to be, and constantly resets to achieve that level, regardless of load.
