Many investigations, confirmed by theoretical studies (Maher and Stevenson, 1988), indicate that the heavy bombardment of the primeval Earth about 3.8 billion years ago led to its sterilisation, so it was practically uninhabitable . The time stamp for the first stromatolith-forming prokaryotes, about 3.5 billion years ago (Schopf, 1993), does not in fact mark the beginning of the biogenesis process, but the appearance of quite complex life forms. Thus, the point at which the first primitive living systems appeared must have been considerably earlier. 

Microcontact printing (pCP) is a technique that uses an elastomeric stamp with relief on its surface to generate patterned SAMs on the surface of both planar and curved substrates [87,88]. SAMs are highly ordered molecular assemblies that form spontaneously by chemisorption of functionalized long-chain molecules on the surfaces of appropriate substrates [79,89]. Well-established systems of SAMs include alkanethiolates on coinage metals (Au, Ag, Cu) [90] alkyl-siloxanes on hydroxyl-terminated surfaces (Si/Si02, glass) [91] carboxylic and... 

LSD LSD is the most potent hallucinogenic drug and produces significant psychedelic effects with a total dose of as httle as 25-50 pg. LSD is sold on the ilhcit market in a variety of forms. A popular contemporary system involves postage stamp-sized papers impregnated with varying doses of LSD (50-300 pg or more). 

In STAMP, accidents and losses result from not enforcing safety constraints on behavior. Not only must the original system design incorporate appropriate constraints to ensure safe operations, but the safety constraints must continue to be enforced as changes and adaptations to the system design occur over time. This goal forms the basis for safe management, development, and operations.

In recent years, self-assembly was successfully applied in micrometer-scale structures. Self-assembled monolayer (SAM) [11] is the representative example of self-assembly microfabrication, in which stufaces consist of a single layer of molecules on a substrate. SAMs can be prepared simply by adding a solution of the desired molecule onto the substrate surface and washing off the excess. The technique was utilized on the metal substrates with PDMS stamps to form the combined system for controlling of crystal nucleation [12]. Another example involves a fluidic technique based on patterned hydrophobic SAMs and capillary forces to self-assemble micro-fabricated sihcon blocks onto silicon and quartz substrates [13]. 

Material to be molded is placed in a matched-metal-die mold cavity and the mold closed. The part is formed by compressing the material under heat and pressure until the resin is cured or sufficiently cool to allow removal. Suitable for she (SMC) or bulk molding compounds (BMC), jH-eforms, w resin applied to reinfracemoit in the mold (wet system molding) or reinforced thermoplastic sheet (hot stamping).
