FluidizationFluidization (or fluidisation) is a process similar to liquefaction whereby a granular material is converted from a static solid-like state to a dynamic fluid-like state. This process occurs when a fluid (liquid or gas) is passed up through the granular material. When a gas flow is introduced through the bottom of a bed of solid particles, it will move upwards through the bed via the empty spaces between the particles. At low gas velocities, aerodynamic drag on each particle is also low, and thus the bed remains in a fixed state.
Flow cytometryFlow cytometry (FC) is a technique used to detect and measure physical and chemical characteristics of a population of cells or particles. In this process, a sample containing cells or particles is suspended in a fluid and injected into the flow cytometer instrument. The sample is focused to ideally flow one cell at a time through a laser beam, where the light scattered is characteristic to the cells and their components. Cells are often labeled with fluorescent markers so light is absorbed and then emitted in a band of wavelengths.
Intangible propertyIntangible property, also known as incorporeal property, is something that a person or corporation can have ownership of and can transfer ownership to another person or corporation, but has no physical substance, for example brand identity or knowledge/intellectual property. It generally refers to statutory creations, such as copyright, trademarks, or patents. It excludes tangible property like real property (land, buildings, and fixtures) and personal property (ships, automobiles, tools, etc.).
