What is Mechanosynthesis?

0

In chemosynthesis, the traditional (and ubiquitous in nature) method of initiating chemical reactions, many millions or more of the reactant molecules are combined in a liquid or vapor, letting them randomly collide through thermal motion until a sufficient quantity of the desired reaction products are produced. By contrast, in mechanosynthesis, an advanced chemical synthesis technique still in the development process, molecular mechanical systems operating under programmed instructions would bring together a single molecule or atom with another, bonding them together in a directed and orderly fashion. Utilizing this method, undesired reactions could be avoided, and reaction throughput could be increased considerably. Rudimentary mechanosynthesis was already demonstrated with silicon in 2003, by Oyabu et al. Using a scanning tunneling microscope (STM), Oyabu and his collaborators used mechanical force alone to make and break covalent atomic bonds. This feat was performed under cryogeni

Unfortunately, that point in language space was already taken. So I would suggest NC chemistry (Numerically Controlled Chemistry). Machine-phase chemistry is also very good, and more true to the original coinage. Doesn’t invoke high-velocity milling connotations. (But, of course, the organic chemistry people will still think you’re a nutball). — Eugen* Leitl leitl http://leitl.org ______________________________________________________________ ICBM: 48.07100, 11.36820 http://www.ativel.com 8B29F6BE: 099D 78BA 2FD3 B014 B08A 7779 75B0 2443 8B29 F6BE —–BEGIN PGP SIGNATURE—– Version: GnuPG v1.4.1 (GNU/Linux) iD8DBQFDsG15dbAkQ4sp9r4RAoUmAJ4+do+ahL/Doys6XXrs2is4D6nvwQCePgQh l2s3NyHAIcMf
