Total Synthesis of Aspidosperma Family Indole Alkaloids through the iORC Domino Process

This thesis describes a unified strategy for the synthesis of monoterpene indole alkaloids of the Aspidosperma family. These syntheses feature two key steps: (1) a palladiumcatalyzed decarboxylative vinylation that provides quick access to cyclopentene int ...

Synthesis factors affecting the catalytic performance and stability of Ru/C catalysts for supercritical water gasification

Christian Ludwig, Frédéric Vogel, Gaël Peng

Catalytic supercritical water gasification of isopropanol (450 degrees C, 30 MPa) over Ru/C catalysts was carried out in a fixed-bed plug flow reactor. In the absence of Ru, isopropanol decomposed to solid carbon (coke), and H-2 over the carbon support. Th ...

Effect of carbon material on Pd catalyst for formic acid electrooxidation reaction

Ligang Feng

Effect of several usually used carbon materials on Pd catalyst for formic acid electrooxidation reaction is studied by physical characterization and electrochemical measurements. New active sites are formed due to the Pd and carbon interaction which is con ...

Efficient reduction of bromates using carbon nanofibre supported catalysts: Experimental and a comparative life cycle assessment study

Lioubov Kiwi

Structured hierarchical catalysts were developed for efficient reduction of bromates in water. In the catalysts a small amount of active metal, 0.3 wt.% Pd, is supported onto carbon nanofibres grown either on sintered metal fibres or on a carbon cloth. In ...

Benchmarking Organic Micropollutants in Wastewater, Recycled Water and Drinking Water with In Vitro Bioassays

Xiaowei Zhang

Thousands of organic micropollutants and their transformation products occur in water. Although often present at low concentrations, individual compounds contribute to mixture effects. Cell-based bioassays that target health-relevant biological endpoints m ...

Incorporation of advanced aerosol activation treatments into CESM/CAM5: Model evaluation and impacts on aerosol indirect effects

Yi Zhang, Athanasios Nenes, Xiuwei Zhang

One of the greatest sources of uncertainty in the science of anthropogenic climate change is from aerosol-cloud interactions. The activation of aerosols into cloud droplets is a direct microphysical linkage between aerosols and clouds; parameterizations of ...
