Growth modification of hematite by phosphonate additives

Heinrich Hofmann, Paul Bowen, Ulrich Aschauer

The hydroxylated surface structures of seven morphologically important crystallographic surfaces of hematite were calculated allowing the determination of the surface energies and, consequently,the hematite equilibrium morphology. The docking of two organi ...

Determination of surface properties of various substrates using TiO2 nanorod coatings with tunable characteristics

Raffaella Buonsanti

We present a novel approach to cover different substrates with thin light-sensitive layers that consist of org.-capped TiO2 nanorods (NRs). Such NR-based coatings exhibit an increasing initial hydrophobicity with increasing NR length, and they demonstrate ...

Efficient Product Importance Sampling using Hierarchical Thresholding

We present an efficient method for importance sampling the product of multiple functions. Our algorithm computes a quick approximation of the product on-the-fly, based on hierarchical representations of the Local maxima and averages of the individual terms ...

On the moduli space of singular Euclidean surfaces

Marc Troyanov

The goal of this paper is to develop some aspects of the deformation theory of piecewise flat structures on surfaces and use this theory to construct new geometric structures on the moduli space of Riemann surfaces. ...

Giant spin splitting through surface alloying

Klaus Kern, Marco Grioni, Luca Moreschini, Daniela Pacilè

The long-range ordered surface alloy Bi/Ag(111) is found to exhibit a giant spin splitting of its surface electronic structure due to spin-orbit coupling, as is determined by angle-resolved photoelectron spectroscopy. First-principles electronic structure ...

A Generic Approach Towards Nanostructured Surfaces Based on Supramolecular Nanostamping on Reactive Polymer Coatings

Francesco Stellacci

Various surfaces can successfully be coated with reactive polymer coatings and then patterned with DNA features using supramocular nanostamping (SuNS). Surfaces as different as silicon, quartz, polystyrene, PMMA and PDMS have been patterned using the same ...

Revisiting the open plan: Ceilings and furniture as display surfaces for building information

Jeffrey Huang, Mark Meagher

First developed by the architectural avante-garde in the early 20th century, the idea of the open plan was the result of a desire for greater transparency and flexibility in the design of interior environments. Essential to the functioning of the open plan ...

Local work function changes determined by field emission resonances: NaCl/Ag(100)

Wolf-Dieter Schneider, François Patthey, Marina Pivetta

Electrons trapped in field emission resonances (FERs) in front of a Ag(100) surface covered with ultrathin NaCl islands are probed by scanning tunneling spectroscopy. The eigenstates in the potential well formed between the tip and the sample are calculate ...

Modélisation itérative de courbes et surfaces: aspect multi-résolution

Yves Weinand, Ivo Stotz, Gilles Gouaty, Eric Tosan

Nous présentons un modèle itératif de figures à motifs fractals. Ce modèle est exprimé dans un formalisme type IFS (Iterated Function System), qui est relié à l’approche par schéma de subdivision. Ce modèle itératif permet de définir des formes à pôles mul ...

Core-level photoelectron spectroscopy probing local strain at silicon surfaces and interfaces

Alfredo Pasquarello, Oleg Yazyev

Using a first-principles approach, we investigate the origin of the fine structure in Si 2p photoelectron spectra at the Si(100)2x1 surface and at the Si(100)-SiO2 interface. Calculated and measured shifts show very good agreement for both systems. By usin ...
