WebPostdoctoral Researcher at the laboratory of Catalysis, Polymerisation, Process and Materials (CP2M) ... we have studied three cryptophanes bearing a tether with an unsaturated bond. The idea behind this is to build probes that can be detected both via hyperpolarised 129Xe NMR and para‐hydrogen induced polarisation 1H NMR. WebHere, by using sitedirected mutagenesis, the role played by Arg60 and Tyr61 in a unique surface loop of TmCel12A was investigated. The results are consistent with the previously observed hydrogen bonding and stacking interactions between these two residues and the …
Boronic Acids as Hydrogen Bond Donor Catalysts for Efficient …
Webdual hydrogen bonding catalysts was investigated by the Rawal group (Figure 1). 25. More recently, Ertürk and coworkers described the use of chiral HAROLs (6) as hydrogen bonding catalysts in Morita–Baylis–Hillman reactions and as ligands for the enantioselective addition reactions of organometallic compounds to aldehydes (Figure … WebThe reactions were conducted in a batch reactor at a temperature of 200 °C for 3 h. The effects of ZnCl2 catalyst loading on CTW were studied. The characteristics of hydrochars in terms of surface morphologies, hydrogen/carbon (H/C) and oxygen/carbon (O/C) ratios and surface functional groups were affected by the ZnCl2 loading on CTW. free printable vehicle inspection sheets
