We couple fundamental surface thermodynamics and autonomous self-assembly processes to address these challenges. This talk explores the latter by using speciation in metal passivating oxide<sup>1<\/sup> as a filter (gate) to controllably introduce metal ions into a solution where only low concentrations of the ions can exist.<sup>2<\/sup> Coupling ion supply to precipitation allows for continuous product generation. Multi-metal center organometallic components\/wires can therefore be made and either locally deposited or <em>in situ<\/em> self-assembled through polymerization-induced self-assembly of 1D organometallic adducts.<sup>3<\/sup> This process, being a living polymerization <em>ad infinitum<\/em> growth, leads to high aspect ratio organometallic micro- to nanomaterials. Post-synthesis pyrolysis of the ligands leads to carbon-coated metal oxides that show catalytic activity atypical of the parent oxide<sup>4<\/sup> and unique transistor behavior<sup>3<\/sup> hinting to low-cost fabrication of diodes, gates, and other microelectronic components. Guided deposition of these adducts allows for multi-semiconductor FINFET morphologies to be realized without the need for typical complex fabrication processes.<sup>3<\/sup> Similar approach with rare earths leads to tunable magnetic properties and realization of lanthanide based crystalline quantum spin liquids<sup>5<\/sup> or tunable color materials.<sup>6<\/sup> In conclusion, we highlight the versatility of nanoscale surfaces\/interfaces in liquid metals as a pathway to neoteric materials or technologies.<\/p>\n\n\n\n<p><strong>References:<\/strong><strong><\/strong><\/p>\n\n\n\n<ol class=\"wp-block-list\" type=\"1\">\n<li><em>J.
