Moieties are the smallest building blocks handeded in the advanced mechanosynthesis of technology level III and II. When a simple resource molecule is picked up with an empty tooltip one always ends up with a few atoms on the tooltip. Some bonds need to be broken open to make it a reactive radical ready for deposition. It is generally not necessary to prepare the picked up molecule down until only one atom is left. That is in most cases one does not put down single atoms but small moieties (always bond molecules). Most often unused bonds are left hydrogen capped and and only one or two bonds are actively used - the one to the tooltip and the one to the workpiece. Hydrogen and oxygen with one and two bonds respectively are subject for single atomic deposition. The heavier elements of the same groups - the halogenes calcogenes - too.
Contents
simple respurce molecules
For mechanosynthesis of diamond ethyne C2H2 methane CH4 and traces of digermane Ge2H6 can be used. This has been toroughly analyzed.
Further molecules of prime interest are carbon dioxide CO2 water H2O and nitrogen gas N2. The capability of handling those allows for tapping the air as a resource for products that (almost) exclusively contain diamondoid molecular elements out of hydrogen carbon oxygen and nitrogen (HCON).
From the metals Aluminum and Titanium would be of interest.
Resource molecules for other elements should preferentially be non or at least low toxic and easy to handle.
- for boron: B2H6 diborane is toxic and reacts with water to
B(OH)3 boric acid which is pretty harmless and thus a better resource - for fluorine: SF6 sulfur hexafluoride very heavy pretty inert gas, soluble in ethanol
the sulfur can be used ore disposed as diluted sulfuric acid - for aluminum: ?
- for silicon: silicic acid self polymerizes and is thus not suitable
SiH4 [1] seems better but it's quite toxic, higher silans tend to be explosive - for phosphorus: PH3 phosphine seems too toxic
H3O4P phosphoric acid seems good
- for chlorine: dissolved table salt NaCl - or diluted hydrochloric acid
Sources for sulfur

- ammonium sulfate (NH4)2SO4 (wikipedia) - pro: waste nitrogen can go to atmosphere, massively available - con: explosive in dry form
- methylsulfonylmethane C2H6O2S- (wikipedia) - pro: non toxic - con: carries carbon too
- sulfuric acid H2SO4 (wikipedia) - pro: massively available - con: acidity
maybe interesting
- carbon disulfide CS2 (wikipedia) - soluble in ethanol - con: toxic
- hydrogen sulfide H2S, sulfur dioxide SO2, sulfur trioxide SO3 - all too dangerous and toxic
- thioacetic acid C2H4OS (wikipedia),
- syn-Propanethial-S-oxide C3H6OS (wikipedia) - irritant expelled by cut onions
- diallyl trisulfide C6H10S3 (wikipedia) - main component of garlic oil
