Abstract: Some exemplary embodiments of the invention relate to performing atomic layer deposition (ALD) or molecular layer deposition (MLD) of a volatile organo silyl lithium compound and ozone on a substrate. According to various exemplary embodiments of the invention the volatile organo silyl lithium compound includes SiLi2tBuMe and/or tBuMe2SiLi and/or tBuMe2SiNa and/or SiLi3Et and/or Alk3GeLi and/or [(Alk3Si)4Al]Li and/or (NMe2)(tBu)2SiLi and/or tBuMe2SiLi-TMEDA and/or SiLi+TMA2tBuMe. Resultant coated products and their uses are also disclosed.

Abstract: Provided are methods for depolymerizing polyesters, e.g., PET, PBT, and PEN. In embodiments, a method for depolymerizing a polyester comprises combining a polyester comprising a plurality of ester linking groups (R?C(O)OR), a metal triflate catalyst, and a hydrogenation catalyst, under conditions to cleave a C—O bond in an alkoxy group (OR) of an ester linking group of the plurality of ester linking groups.

Abstract: A method for depolymerizing a polyester may comprise heating a polyester at a temperature and for a period of time in the presence of a supported metal-dioxo catalyst, optionally, in the presence of H2, to induce hydrogenolysis of ester groups in the polyester and provide monomers of the polyester.
