PLASMA PROCESSING

Methods and technologies that utilize a plasma to treat and manufacture materials, generally through etching, deposition, or chemical alteration at a surface inside or at the boundary of the plasma.

MEMBRANE ANALOGY

A formal identity between the differential equation and boundary conditions for a stress function for torsion of an elastic prismatic bar, and those for the deflection of a uniformly stretched membrane with the same boundary as the cross section of the bar, subjected to a uniform pressure.

LOT LINE

The legal boundary line of a piece of property.

JUNCTION PHENOMENA

Phenomena which occur at the boundary between two semiconductor materials, or a semiconductor and a metal, such as the existence of an electrostatic potential in the absence of current flow, and large injection currents which may arise when external voltages are applied across the junction in one direction.

ANTI-WEAR ADDITIVE

Improves the service life of tribological elements operating in the boundary lubrication regime. Anti-wear compounds (for example, ZDDP and TCP) start decomposing at 90° to 100°C and even at a lower temperature if water (25 to 50 ppm) is present.

FRICTION

The resisting force encountered at the common boundary between two bodies when, under the action of an external force, one body, moves or tends to move relative to the surface of the other.

INTERFACIAL TENSION (IFT)

The energy per unit area present at the boundary of two immiscible liquids. It is usually expressed in dynes/cm (ASTM Designation D 971.)

OILINESS

That property of a lubricant that produces low friction under conditions of boundary lubrication. The lower the friction, the greater the oiliness.

INSHORE TRAFFIC ZONE

A routing measure comprising a designated area between the landward boundary of a traffic separation scheme and the adjacent coast, intended for local traffic

BOUNDARY MONUMENT

A material object placed on or near a boundary line to preserve and identify the location of the boundary line on the ground.
