Liquid mercury is a special case as it typically acts as a simple metal, so has been used as a reference electrode. [2] More common is water, and electricity due to water droplets hitting surfaces has been documented since the discovery by Philipp Lenard in 1892 of the spray electrification or waterfall effect .
Cats are highly territorial in nature, and to them, the arrival of a new feline could be seen as an encroachment on their territory. Therefore, there are steps to take if you want to guarantee a ...
Foam insulation serves as a barrier to airborne sounds, and reduces airborne sound transfer through a building's roof, floor and walls compared an uninsulated structure. [15] In the United States, homes treated with spray foam insulation often qualify for state and federal tax deductions. [16] Insulation of all types stops a good deal of energy ...
Air barrier systems – Combinations of air barrier assemblies and air barrier components, connected by air barrier accessories, that are designed to provide a continuous barrier to the movement of air through an environmental separator, which has an air leakage rate no greater than 2.00 L/(s•m 2) at a pressure difference of 75 Pa when tested ...

The function of a vapor barrier is to retard the migration of water vapor. A vapor barrier is not typically intended to retard the migration of air. This is the function of air barriers. [8] Air is mixed with water vapor. When air moves from location to location due to an air pressure difference, the vapor moves with it.
Dielectric-barrier discharge (DBD) is the electrical discharge between two electrodes separated by an insulating dielectric barrier. [1] Originally called silent (inaudible) discharge and also known as ozone production discharge [ 2 ] or partial discharge , [ 3 ] it was first reported by Ernst Werner von Siemens in 1857.
