Diffusers can be as a shape of round, rectangular, or can be as linear slot diffusers (LSDs). E.g., linear slot diffusers take the form of one or several long, narrow slots, mostly semi-concealed in a fixed or suspended ceiling with airfoils behind the slots directing the airflow in the desired direction. Occasionally, diffusers are mostly used ...
Aroma lamp with essential oil. A heat diffuser contains a small candle under a bowl to vaporize a mixture of water and oil. This device is very cheap and doesn't need a special maintenance, however, the heat can change the chemical structure of the oils.
Diffuser (hair), a blowdryer attachment that diffuses heat as it dries the hair; Diffuser (heat), a cooking item that is placed above a heating element to separate the cooking utensil from the heat source; Diffuser (optics), a device that spreads out or scatters light; Diffuser (sewage), an aerating device for sewage and industrial waste water ...
A slot-waveguide is an optical waveguide that guides strongly confined light in a subwavelength-scale low refractive index region by total internal reflection.. A slot-waveguide consists of two strips or slabs of high-refractive-index (n H) materials separated by a subwavelength-scale low-refractive-index (n S) slot region and surrounded by low-refractive-index (n C) cladding materials.
This design amplifies the positive effects of a normal diffuser shroud to result in a more efficient diffuser. The brimmed exit hole creates stronger vortices than a regular diffuser, which means that the pressure difference is greater than it would be with a normal diffuser. [2] As a result, wind is able to reach higher speeds.

An air diffuser or membrane diffuser is an aeration device typically in the shape of a disc, tube or plate, which is used to transfer air and with that oxygen into the sewage or industrial wastewater. Oxygen is required by microorganisms/bacteria residents in the water to break down the pollutants.
Coarse bubble diffusers produce 1/4 to 1/2 inch (6.4 to 13 mm) bubbles which rise rapidly from the floor of a wastewater treatment plant or sewage treatment plant tank. They are typically used in grit chambers, equalization basins, chlorine contact tanks, and aerobic digesters , and sometimes also in aeration tanks.
