Copper-Catalyzed Formal [2+2+1] Heteroannulation of Alkenes, Alkylnitriles, and Water: Method Development and Application to a Total Synthesis of (±)-Sacidumlignan D

Qian Wang, Jieping Zhu, Minh Tu Ha, Claire Chatalova Sazepin

A copper-catalyzed three-component reaction of alkenes, alkylnitriles, and water affords gamma-butyrolactones in good yields. The domino process involves an unprecedented hydroxy-cyanoalkylation of alkenes and subsequent lactonization with the creation of ...

On-Surface Assembly and Reactions of Organic Molecules in Ultra-High Vacuum

Claudius Morchutt

This thesis comprises the study of two types of 2D materials, those stabilized by non-covalent and those by covalent interactions. They are synthesized and studied on well-defined metallic surfaces in ultra-high vacuum (UHV). The self-assembly of terephtha ...

Understanding the anomalous behavior of Vegard's law in Ce1-xMxO2 (M = Sn and Ti; 0 < x

Olga Safonova

The dependence of the lattice parameter on dopant concentration in Ce1-xMxO2 (M = Sn and Ti) solid solutions is not linear. A change towards a steeper slope is observed around x similar to 0.35, though the fluorite structure (space group Fm3m) is preserved ...

Electrochemical Studies of Water Splitting in Organic Media

Jonnathan Cesar Hidalgo Acosta

The development of new routes towards the generation of environmentally friendly solar fuels, such as molecular hydrogen (H2) for use in fuel cells, is a grand challenge facing the scientific community. In this regard, water splitting represents one of the ...

Atomic bonding effects in annular dark field scanning transmission electron microscopy. I. Computational predictions

Matteo Cococcioni

Annular dark field scanning transmission electron microscopy (ADF-STEM) image simulations were performed for zone-axis-oriented light-element single crystals, using a multislice method adapted to include charge redistribution due to chemical bonding. Exami ...

Ice VII from aqueous salt solutions: From a glass to a crystal with broken H-bonds

Livia Eleonora Bove Kado

It has been known for decades that certain aqueous salt solutions of LiCl and LiBr readily form glasses when cooled to below approximate to 160 K. This fact has recently been exploited to produce a "salty" high-pressure ice form: When the glass is compress ...

CO2 Binding and Induced Structural Collapse of a Surface-Supported Metal-Organic Network

Klaus Kern, Sebastian Stepanow, Christopher Seiji Kley

Extensive efforts have been directed toward identifying catalytic material composites for efficiently transforming CO2 into valuable chemicals. Within this long-standing scientific challenge, the investigation of model systems is of particular interest to ...

Air nonlinearity triggered by an ultra-intense 33 MV/cm and sub-5 THz light bullet

Christoph Peter Hauri, Mostafa Shalaby

We report on measurements of the instantaneous Kerr nonlinearity and the retarded alignment of non-polar molecules CO2, N-2, and O-2 by an intense, lambda-cubic terahertz pulse with peak field > 33 MV/cm centered at 3.9 THz. ...

Molecular Effects of Concentrated Solutes on Protein Hydration, Dynamics, and Electrostatics

Matteo Dal Peraro, Luciano Andres Abriata, Enrico Spiga

Most studies of protein structure and function are performed in dilute conditions, but proteins typically experience high solute concentrations in their physiological scenarios and biotechnological applications. High solute concentrations have well-known e ...
