Abstract: Processes for conductive material nanogap formation have been developed that include: providing a base material, wherein the base material is either solid or comprises a micropore that extends through the first layered material, and wherein the micropore comprises a top opening, a bottom opening, and a volume boundary, applying a conductive material sheet to the first layered material, wherein the conductive material sheet covers the top opening of the micropore, applying two conducting electrodes to the conductive material sheet, so that each one of the conducting electrodes is positioned on either side of the micropore, applying an etch mask that covers at least a part of the conductive material sheet, the top opening of the micropore (if present), or a combination thereof, applying a passivation layer over at least the etch mask, fabricating a hole in the passivation layer directly above the top opening of the micropore, and applying at least one voltage pulse through the at least one conducting electrode to create a nanogap in the conductive material sheet, wherein the nanogap is over and open to the top opening of the micropore. In some embodiments, the micropore and the nanogap are fabricated simultaneously.

Abstract: Contemplated subject matter disclosed herein relates generally to organometallic olefin metathesis catalysts, and more particularly to longer-lived olefin metathesis catalysts supported by hemi-labile carbene ligands that bear an arm with one or more donor ligands, as well as the use of such catalysts in metathesis reactions of olefins and olefin compounds. The contemplated subject matter has utility in the fields of catalysis, organic synthesis, polymer chemistry, and industrial and fine chemicals chemistry. This contemplated subject matter serves to reduce the cost of olefin metathesis (OM) processes including in olefin metathesis polymerizations, conversion of vegetable oils into chemicals, and processes in the petrochemical industry. This contemplated subject matter reduces the cost of OM processes by providing OM catalysts that are longer-lived and lead to higher turnover numbers, hence requiring less catalyst to convert a given amount of substrate(s). Considering that the OM catalyst is the most expensive part of some OM processes, longer-lived OM catalysts have the benefit of reducing the overall cost of the OM processes.
