Surface Discharge in Liquid Nitrogen

Resistive Liquid-Vapor Surface Sensors for Liquid Nitrogen and Hydrogen

Ten resistance thermometers were tested as point sensors for detecting the liquid-vapor interface in liquid nitrogen and liquid hydrogen. Test results showed that most could be made to detect the liquid surface and lead orientation can be important. A silicon resistive sensor had the fastest response and produced the greatest signal change.

Liquid nitrogen cryotherapy for surface eye disease (an AOS thesis).

PURPOSE To evaluate the effects of new treatments with liquid nitrogen cryotherapy on some external eye conditions. METHODS In this retrospective case study, 6 separate series from a single tertiary care referral center practice are described. Liquid nitrogen cryotherapy was used to treat conjunctival amyloidosis, primary pterygia, recurrent pterygia, advancing wavelike epitheliopathy (AWLE),...

Surface Decontamination by Dielectric Barrier Discharge Plasma

Background: Dielectric barrier discharge (DBD), a source of non-thermal plasma, is used in surface decontamination. Objective: To study the effect of DBD plasma treatment, we evaluated the effect of plasma exposure time on inactivation of Bacillus subtilis. Results: Applying the DBD plasma to the culture of B. subtilis caused complete sterilization of the surface without any thermal effects. In...
