Selective catalytic reduction (SCR) is a means of converting nitrogen oxides, also referred to as NO x with the aid of a catalyst into diatomic nitrogen, N 2, and water, H 2O. A gaseous reductan...
Nonimaging radiant energy device
The expense of refrigeration led to the early dismissal of low temperature superconductors for use in magnetic bearings. However, high-temperature superconductor (HTSC) bearings may be economical a...
Flywheel energy storage (FES) works by accelerating a rotor (flywheel) to a very high speed and maintaining the energy in the system as rotational energy. When energy is extracted from the system, ...
Analytical electron microscope cleaning
Superconductivity is a phenomenon of exactly zero electrical resistance and expulsion of magnetic fields occurring in certain materials when cooled below a characteristic critical temperature. It w...
Nuclear fuel is a material that can be 'burned' by nuclear fission or fusion to derive nuclear energy. Nuclear fuel can refer to the fuel itself, or to physical objects (for example bundles compose...
Salt recovery from waste water
Weld monitoring methods are used to assure the quality and correctness of the weld during the process of welding. The term is generally applied to automated monitoring for weld-quality purposes and...
An internal combustion engine (ICE) is an engine where the combustion of a fuel occurs with an oxidizer (usually air) in a combustion chamber that is an integral part of the working fluid flow circ...
Ultrasonic testing (UT) is a family of non-destructive testing techniques based in the propagation of ultrasonic waves in the object or material tested. In most common UT applications, very short u...
Separation of different plastics
The Epstein–Barr virus vaccine is a vaccine against the Epstein–Barr virus. The vaccine is not yet available,[1] but it is in clinical trials.[2][3][4] Gp350/220[further explanation needed] is the ...
Previously, hydrogen peroxide has been prepared industrially by hydrolysis of the ammonium peroxydisulfate, which was itself obtained via the electrolysis of a solution of ammonium bisulfate (NH 4...
Power transmission is the movement of energy from its place of generation to a location where it is applied to performing useful work. Power is defined formally as units of energy per unit time.
Porous silicon (p-Si) is a form of the chemical element silicon that has introduced nanoporous holes in its microstructure, rendering a large surface to volume ratio in the order of 500 m2/cm3.
Hydrogen sulfide wastes
An electromagnetic pump is a pump that moves liquid metal (or any electrically conductive liquid) using electromagnetism. A magnetic field is set at right angles to the direction the liquid moves i...
