groove technology with Sealol welded metal bellows, resulting in a seal that eliminates face contact and wear and offers precise face loading and resistance to hang-up.
The Type 285 seal operates on a gas film. The small amount of heat generated at the seal interface vapourises the fluid. The spiral grooves gather and compress the gas. As the gas is forced towards the closed groove ends, the pressure rises and creates a gas cushion, separating the sealing faces.
This spiral groove technology also minimises product loss, reduces power consumption and eliminates the need for costly support systems.

We have studied Fermi level pinning (FLP) of Hf-based high-k gate stacks based on thermodynamics based on an O vacancy model. Our study shows that FLP cannot be avoided when the system is under thermal equilibrium. O exposure to aim O vacancy elimination is not effective, since O vacancy elimination
