Reliable Langmuir Blodgett colloidal masks for large area nanostructure realization

Olivier Martin, Christian Santschi, Madasamy Thangamuthu

The fabrication of highly ordered nanostructures over large areas is key for many technologies and colloidal lithography using the Langmuir Blodgett technique appears a simple and straightforward way of reaching that goal. While this technique has been wid ...

Specific Ion Effects at the Interface of Nanometer-Sized Droplets in Water: Structure and Stability

Sylvie Roke, Halil Ibrahim Okur, Evangelia Zdrali

The interaction of ions with interfaces influences numerous processes in chemistry, physics, and biology, while different ion species behave differently at hydrophobic or hydrophilic interfaces. Despite its importance, ion specificity and its relation to s ...

The Diverse Nature of Ion Speciation at the Nanoscale Hydrophobic/Water Interface

Sylvie Roke, Halil Ibrahim Okur, Evangelia Zdrali

Many biological systems are composed of nanoscale structures having hydrophobic and hydrophilic groups adjacent to one another and in contact with aqueous electrolyte solution. The interaction of ions with such structures is of fundamental importance. Alth ...

Post-synthesis deposition of mesoporous niobic acid with improved thermal stability by kinetically controlled sol–gel overcoating

Jeremy Luterbacher, Florent Emmanuel Héroguel, Yuan-Peng Du

Niobia is a well-known solid acid catalyst owing to its intrinsic Brønsted and Lewis acidity. However, catalyst development with this oxide has been limited by our ability to control its pore structure and thermal stability. Here we report a novel post-syn ...

Molecular Level Interfacial Studies of Nanoemulsions: Surface Structure, Specific Ion Effects and Stability

Evangelia Zdrali

This thesis is a study on the molecular structure of the interface of nanometer-sized oil droplets dispersed in water, a system known as oil-in-water nanoemulsion. The motivation for this research is the large significance of the interfacial nanostructures ...

Dimensional effects on the tunneling conductivity of gold-implanted nanocomposite films

Claudio Grimaldi

We study the dependence of the electrical conductivity on the gold concentration of Au-implanted polymethylmethacrylate (PMMA) and alumina nanocomposite thin films. For Au contents larger than a critical concentration, the conductivity of Au-PMMA and Au-al ...

Characterization of Solid-Liquid Interfaces with High-Resolution Atomic Force Microscop

Maria Ricci

Solid-liquid interfaces are ubiquitous. Despite the unquestioned relevance, many scientific research fields rely on simplified or macroscopic descriptions, discarding the molecular nature of the constituents. However, it is the specific molecular interacti ...
