In electrical and safety engineering, hazardous locations (HazLoc, pronounced haz·lōk) are places where fire or explosion hazards may exist. Sources of such hazards include gases, vapors, dust, fibers, and flyings, which are combustible or flammable. Electrical equipment installed in such locations can provide an ignition source, due to ...
The advanced microwave sounding unit ( AMSU) is a multi-channel microwave radiometer installed on meteorological satellites. The instrument examines several bands of microwave radiation from the atmosphere to perform atmospheric sounding of temperature and moisture levels. Flooding from Hurricane Isidore shown by AMSU channel 2.
Air purifier. An air purifier or air cleaner is a device which removes contaminants from the air in a room to improve indoor air quality. These devices are commonly marketed as being beneficial to allergy sufferers and asthmatics, and at reducing or eliminating second-hand tobacco smoke .
Piranha solution, also known as piranha etch, is a mixture of sulfuric acid ( H2SO4) and hydrogen peroxide ( H2O2 ). The resulting mixture is used to clean organic residues off substrates, for example silicon wafers. [ 1] Because the mixture is a strong oxidizing agent, it will decompose most organic matter, and it will also hydroxylate most ...

While this version of the microwave has a 0.7-cubic-foot capacity, the appliance is also available in two larger sizes, both of which still cost less than $150.
Dielectric resonator. A dielectric resonator is a piece of dielectric ( nonconductive but polarizable) material, usually ceramic, that is designed to function as a resonator for radio waves, generally in the microwave and millimeter wave bands. The microwaves are confined inside the resonator material by the abrupt change in permittivity at the ...
