Probing Water Dissociation and Oxygen Replacement on Partially Oxygen-Covered Cu(111) by Reflection Absorption Infrared Spectroscopy

Rainer Beck, Harmina Vejayan, Mateusz Suchodol

The presence of chemisorbed oxygen on the Cu(111) surface is known to strongly reduce the activation barrier for water dissociation as compared to bare Cu(111). Here, we present direct experimental evidence for the hydrogen abstraction mechanism responsibl ...

Programming of Multicellular Patterning with Mechano-Chemically Microstructured Cell Niches

Pierre Osteil

Multicellular patterning of stem-cell-derived tissue models is commonly achieved via self-organizing activities triggered by exogenous morphogenetic stimuli. However, such tissue models are prone to stochastic behavior, limiting the reproducibility of cell ...

ISSCR standards for the use of human stem cells in basic research

Matthias Lütolf

The laboratory culture of human stem cells seeks to capture a cellular state as an in vitro surrogate of a biological system. For the results and outputs from this research to be accurate, meaning-ful, and durable, standards that ensure reproducibility and ...

Optimized Modeling of Metastatic Triple-Negative Invasive Lobular Breast Carcinoma

Cathrin Brisken, Laura Battista, Georgios Sflomos

Simple Summary Invasive lobular carcinoma (ILC) is the second most common histologic subtype of breast cancer and is often detected at an advanced stage. Up to 30% of ILC cases relapse and present a challenge for treatment. Unfortunately, there are few mod ...

Gas/Surface reactions probed by reflection absorption infrared spectroscopy

Harmina Vejayan

In my thesis, I present an investigation of the dissociation reactions of gas phase molecules on single crystal metal surfaces studied by a molecular beam in combination with Reflection Absorption Infrared Spectroscopy (RAIRS). Two gas/surface systems were ...

Design of experiments to investigate multi-additive cellulose nanocrystal films

Tiffany Abitbol

Cellulose nanocrystal (CNC) suspensions can self-assemble into chiral nematic films upon the slow evaporation of water. These films are brittle, as indicated by their fracturing instead of plastically deforming once they are fully elastically deformed. Thi ...

Water photo-oxidation on self-assembled organic/Co3O4 metal junctions in biphasic systems

Hubert Girault, Astrid Johana Olaya Avendano, Julieta Soledad Riva

A microwater vertical bar butyronitrile (W vertical bar BCN) interface was used to study the effect of the interfacial chemical polarization on the efficiency of the visible-light induced water oxidation reaction (WOR) by the electron acceptor/ photosensit ...

Structures of SAS-6 coiled coil hold implications for the polarity of the centriolar cartwheel

Pierre Gönczy, Georgios Hatzopoulos

Centrioles are eukaryotic organelles that template the formation of cilia and flagella, as well as organize the microtubule network and the mitotic spindle in animal cells. Centrioles have proximal-distal polarity and a 9 fold radial symmetry imparted by a ...

Investigating the morphological transitions in an associative surfactant ternary system

Julian Charles Shillcock

Associative surfactants systems involving polar oils have recently been shown to stabilize immiscible liquids by forming nanostructures at the liquid interface and have been used to print soft materials. Although these associating surfactant systems show g ...

Increasing Magnetic Anisotropy in Bimetallic Nanoislands Grown on fcc(111) Metal Surfaces

Harald Brune, Stefano Rusponi, Sergio Vlaic, Dimitrios Mousadakos

The magnetic properties and the atomic scale morphology of bimetallic two-dimensional nanoislands, epitaxially grown on fcc(111) metal surfaces, have been studied by means of Magneto-Optical Kerr Effect and Scanning Tunneling Microscopy. We investigate the ...
