Plasma activation (or plasma functionalization) is a method of surface modification employing plasma processing, which improves surface adhesion properties of many materials including metals, glass, ceramics, a broad range of polymers and textiles and even natural materials such as wood and seeds.
Salen is a typical metal-deactivator. Metal deactivators, or metal deactivating agents (MDA) are fuel additives and oil additives used to stabilize fluids by deactivating (usually by sequestering) metal ions, mostly introduced by the action of naturally occurring acids in the fuel and acids generated in lubricants by oxidative processes with the metallic parts of the systems.
Mobile fab lab. The mobile fab lab is a computer-controlled design and machining fab lab housed in a trailer. The first was built in August 2007 by the Center for Bits and Atoms at the Massachusetts Institute of Technology. [1]
Activators – chemicals disrupting/dissolving the metal oxides. Their role is to expose unoxidized, easily wettable metal surface and aid soldering by other means, e.g. by exchange reactions with the base metals.
The decrease of temperature is based on the increase of bonding strength using plasma activation on clean wafer surfaces. Further, the increase is caused by elevation in amount of Si-OH groups, removal of contaminants on the wafer surface, the enhancement of viscous flow of the surface layer and the enhanced diffusivity of water and gas trapped at the interface.

Diverse mechanisms have been proposed for the formation of MAO and many structures as well. Chen, E. Y.-X.; Marks, T. J. (2000). "Cocatalysts for Metal-Catalyzed Olefin Polymerization: Activators, Activation Processes, and Structure-Activity Relationships".

As previously stated, in FAB the samples are mixed with a non-volatile environment in order to be analyzed.FAB uses a liquid matrix that is mixed with the sample in order to provide a sample ion current that is sustained, reduces damages made to the sample by absorbing the impact of the primary beam, and keeps the sample molecules form aggregating.
