Catalyst support and solvent effects during lignin depolymerization and hydrodeoxygenation

Jeremy Luterbacher, Florent Emmanuel Héroguel

We studied and compared the hydrodeoxygenation (HDO) and depolymerization of aldehyde-stabilized lignin and 4-propylguaiacol (PG), a model lignin monomer. We demonstrated by liquid phase adsorption that PG HDO catalyzed by Ru/C can be achieved in isooctane ...

Hydration mediated interfacial transitions on mixed hydrophobic/hydrophilic nanodroplet interfaces

Sylvie Roke, Halil Ibrahim Okur, Nikolay Smolentsev, Rüdiger Scheu, Filip Kovacik

Interfacial phase transitions are of fundamental importance for climate, industry, and biological processes. In this work, we observe a hydration mediated surface transition in supercooled oil nanodroplets in aqueous solutions using second harmonic and sum ...

CO2 hydrogenation reaction over pristine Fe, Co, Ni, Cu and Al2O3 supported Ru: Comparison and determination of the activation energies

Andreas Züttel, Wen Luo, Noris André Gallandat, Robin Tobias Andreas Mutschler, Emanuele Moioli

Fe, Co, Ni and Cu are the main non-noble industrially significant catalysts in the CO2 and CO gas phase hydrogenation reaction towards hydrocarbons and alcohols. These catalysts are typically supported on metal oxides such as SiO2, TiO2, Al2O3 and ZnO, in ...

Enantioselective Synthesis of Chiral-at-Sulfur 1,2-Benzothiazines by (CpRhIII)-Rh-x-Catalyzed C-H Functionalization of Sulfoximines

Nicolai Cramer, Yang Sun

Sulfoximines with stereogenic sulfur atoms are attractive structural motifs in drug discovery. A direct catalytic enantioselective method for the synthesis of sulfur-chiral 1,2-benzothiazines from readily accessible diaryl sulfoximines is presented. Rhodiu ...

Predicting Product Distribution of Propene Dimerization in Nanoporous Materials

Berend Smit

In this work, a theoretical framework is developed to explain and predict changes in the product distribution of the propene dimerization reaction, which yields a mixture of C-6 olefin isomers, resulting from the use of different porous materials as cataly ...

Effects of Pore and Cage Topology on the Thermodynamics of n-Alkane Adsorption at Bronsted Protons in Zeolites at High Temperature

Berend Smit

Monte Carlo simulations are used to systematically investigate the effects of structural topology on the thermodynamics of n-alkanes adsorbed at Bronsted protons in zeolites having one-dimensional channel systems. In zeolites without cages, the enthalpy an ...

"Divergent Total Synthesis of (-)-Rhazinilam, (-)-Leucomidine B and (+)-Leuconodine F" and "Synthetic Studies Towards Sarpagine-Related Indoles"

Dylan Jean Robert Dagoneau

The work presented in this thesis focuses on the synthesis of monoterpene indole alkaloids. The first part describes the divergent total synthesis of (-)-rhazinilam, (-)-leucomidine B and (+)-leuconodine F, three structurally distinct natural products of t ...

Predicting Partitioning and Diffusion Properties of Nonpolar Chemicals in Biotic Media and Passive Sampler Phases by GC x GC

Jeremy Samuel Arey, Deedar Nabi

The chemical parameters needed to explain and predict bioavailability, biodynamics, and baseline toxicity are not readily available for most nonpolar chemicals detected in the environment. Here, we demonstrate that comprehensive two-dimensional gas chromat ...

Nitrogen, Phosphorus, and Sulfur Co-Doped Hollow Carbon Shell as Superior Metal-Free Catalyst for Selective Oxidation of Aromatic Alkanes

Shuliang Yang, Li Peng

Metal-free heteroatom-doped carbocatalysts with a high surface area are desirable for catalytic reactions. In this study, we found an efficient strategy to prepare nitrogen, phosphorus, and sulfur co-doped hollow carbon shells (denote as NPS-HCS) with a su ...

Freezing effects of oil-in-water emulsions studied by sum-frequency scattering spectroscopy

Sylvie Roke, Nikolay Smolentsev

Temperature-dependent sum-frequency scattering spectroscopy is used to study the properties of hexadecane and dodecane oil droplets in water. The sum-frequency scattering spectra contain vibrational bands that correspond to the symmetric and antisymmetric ...
