AME054  |  Green and Selective Synthesis of Chiral Compounds

Enantiomerically pure molecules are often used in the pharmaceutical and fine chemical industries. These compounds are usually obtained through kinetic resolution of racemic mixtures after chemical synthesis, which may require the use of high cost and toxic catalysts or reagents. The kinetic resolution process may also be expensive and time consuming. A low cost method to synthesize enantiomerically pure molecules or molecules in high enantiomeric excess from low cost and easily available raw materials is widely sought after. This technology relates to the use of cascade biocatalysis (with whole cells) to prepare chiral molecules in high enantiomeric excess.

AME055  |  High Efficiency Graphene Oxide Catalyst for Oxidative Reactions

Carbon catalysts are an attractive alternative for expensive metal catalysts because of their low cost and natural abundance. Graphene oxide sheets, inexpensively prepared from graphite, have been used in place of expensive metal catalysts for various chemical reactions. However, the typically very low catalytic reactivity of graphene oxide often requires a catalyst loading of 200 – 400 wt% to substantially convert a reactant to a desired product. This limits the use of graphene oxide catalysts. This technology provides a graphene oxide catalyst of low catalytic loading (< 5%) designed as a viable option for industrial use.

AME059  |  Catalyst for Producing Chiral and Conductive Selective Single-walled Carbon Nanotubes

Structurally uniform and chirality-pure single-walled carbon nanotubes (SWCNTs) are highly desired for both fundamental studies and technological applications. The ultimate goal of producing just one type of SWCNT by controlling its structure or chirality, during growth has proved to be a considerable challenge over the last two decades. Using high melting point tungsten-based intermetallic compound nanocrystals that can maintain their crystalline structures during the SWCNT growth process as catalysts, allows growth of SWCNTs with specific chirality and different conductivities, with purity between 92 – 98%.
