The hyfrecator does not require a dispersive return pad, referred-to in the electrosurgery field as a "ground pad," or "patient plate," because the hyfrecator can pass a very low-powered current between forceps tips via bipolar output, or pass an A.C. current between one pointed metal electrode probe and the patient, with the patient's self ...

In order to increase the quality of chromatographic output, sturdier devices made of glass have shown the ability to withstand far greater pressure than TPE. Achieving these higher pressures to increase the degree of separation and eliminating all dead volumes through immediate droplet formation has shown the potential for droplet microfluidics ...
A controlled pressure distribution over part surface during forming can be used to “control” the sheet thickness and postpone localized necking. The use of only single form surface tooling, which saves time and expense in the manufacture of tooling.
A spray nozzle or atomizer is a device that facilitates the dispersion of a liquid by the formation of a spray. The production of a spray requires the fragmentation of liquid structures, such as liquid sheets or ligaments, into droplets, often by using kinetic energy to overcome the cost of creating additional surface area.
When a tube of a narrow bore, often called a capillary tube, is dipped into a liquid and the liquid wets the tube (with zero contact angle), the liquid surface inside the tube forms a concave meniscus, which is a virtually spherical surface having the same radius, r, as the inside of the tube. The tube experiences a downward force of magnitude ...
The process of forming a spray is known as atomization. A spray nozzle is the device used to generate a spray. The two main uses of sprays are to distribute material over a cross-section and to generate liquid surface area. There are thousands of applications in which sprays allow material to be used most efficiently.
A water / surfactant (foam) mixture, with compressed air forced into the mix. The result is a very homogeneous, small "air bubble" distribution; the resulting suppression agent is the consistency of soggy shaving cream, consisting of relatively pure surface area and little actual water.
