A system for detecting a possibility of boiling over and preventing said boiling over, the system comprising a vessel (101) having a lid (102), the lid (102) being characterised in that it is configured: to receive information on an initial level of a vessel content and a current level of the vessel content; and based on a difference between the initial level and the current level as well as the time of a creation of said difference: to instruct, by means of a controller (203), a height actuator (207) of the lid (102) to extend said lid (102) vertically, in order to extend the height of said vessel (101); and to instruct, by means of a controller (203), an aperture actuator (206) to create an aperture in a top of the lid (102) in order to facilitate exchange of heat.

An evaporator is provided for evaporating water from an ambient body of water having a water surface. The evaporator includes a housing that has a proximal end proximate to the water surface, a distal end distal to the water surface, and a housing air flow channel directed toward the water surface. The housing is disposed on a support, such as a float assembly, that positions the housing above the water surface. The evaporator also includes an air flow induction device, preferably an impeller, disposed to direct an air flow stream from the distal end toward the proximal end through the housing air flow channel and toward the water surface so that the air contacts the water. The impeller preferably is made of a fiberglass material. The support preferably includes at least one float assembly air flow channel that receives the air flow stream from the housing and directs it outwardly from the evaporator. Water injection devices such as spray nozzles or atomizing nozzles preferably are disposed in the float assembly channel or channels to inject the water into the air flow stream.

An evaporator that includes a porous sintering body is provided. The sintering body is made of a composite consisting of at least one first electrically conductive material and at least one second electrically conductive material as well as at least one dielectric material. The sintering body has an open porosity ranging from 10 to 90%, and the dielectric material is selected from the group consisting of crystallizable glass and/or glass ceramic, wherein the first electrically conductive material has a lower electric conductivity than the second electrically conductive material; the content of dielectric material in the composite equals 5 to 70 vol. %; the content of the first electrically conductive material in the composite equals 10 to 90 vol. %; the content of the second electrically conductive material equals 5 to 50 vol. %; and the sintering body has an electrical conductivity ranging from 0.1 to 105 S/m.

Methods and apparatus for vaporizing liquid into the surrounding environment, including directing liquid from a liquid source to a vaporization port where the vaporization port has lateral dimensions varying from 10 um to 300 um, applying heat to the liquid in the vaporization port with an at least one heating element located in thermal communication to the vaporization port, and releasing vaporized liquid from the vaporization port into the surrounding environment so that fluid is transported through the depth of the structure.

A thermodenuder having a main tube with an outer wall, and a heater (23) arranged within the main tube. The heater is arranged in the center of a cross section through the main tube and is spaced apart from the outer wall of the main tube. The main tube has a main axis of extension, and the heater extends parallel to the main axis. The main tube has two openings that are arranged at opposing side faces of the main tube. A channel for an aerosol is arranged within the main tube between the heater and the outer wall and between the two openings. Furthermore, a method for removing semi-volatile material and semi-volatile particles from an aerosol is provided.

Provided herein are methods, systems, and device for control, delivery, and purification of low vapor pressure gases in conjunction with carrier gas in micro-electronics and other critical process applications. The present invention is based on the observation that when temperature and pressure of a device for delivering a gas stream are held constant, the concentration of vapor in the gas stream may be modulated based on the level of liquid within the chamber thereof.

A three-dimensional surface covering system includes a surface mounting system configured to bond to a mounting surface, the surface mounting system having a panel to secure to the mounting surface; an attachment system; and an aesthetical covering removably secured to the panel via the attachment system; the aesthetical covering can be removed and changed as desired.
