The rotating wall technique (RW technique) is a method used to compress a single-component plasma (a cold dense gas of charged particles) confined in an electromagnetic trap. It is one of many scientific and technological applications that rely on storing charged particles in vacuum.
A Murphy bed (also known as a pull-down bed, fold-down bed, or wall bed) is a bed that is hinged at one end to store vertically against the wall, or inside a closet or cabinet. Since they often can be used as both a bed or a closet, Murphy beds are multifunctional furniture .
The rotating bed reactor is a rather new invention that shows high rates of mass transfer and good fluid mixing. RBR type reactors have frequently been applied in high-value biocatalysis reactions, there offering convenient reuse of immobilized enzymes [ 4 ] while preventing mechanical damage of the solid-phase catalysts.

A rotating biological contactor is a type of secondary (biological) treatment process. It consists of a series of closely spaced, parallel discs mounted on a rotating shaft which is supported just above the surface of the wastewater. Microorganisms grow on the surface of the discs where biological degradation of the wastewater pollutants takes ...
A packed bed used to perform separation processes, such as absorption, stripping, and distillation is known as a packed column. [1] Columns used in certain types of chromatography consisting of a tube filled with packing material can also be called packed columns and their structure has similarities to packed beds.
Figure 10: Centrifuging motion in rotating drum. As the rotational velocity increases further, cataracting motion will transition to centrifuging motion which will result in a lower screening efficiency. This is due to particles attaching to the wall of the rotating drum caused by centrifugal forces as shown in Figure 10.
