Changes in portlandite morphology with solvent composition: Atomistic simulations and experiment

Paul Bowen, Sandra Caroline Galmarini, Nicolas Ruffray

Experimental work has been done to determine changes in the particle shape of portlandite grown in the presence of different ions. To quantify the experimentally observed changes in morphology a new analysis tool was developed, allowing the calculation of ...

Geodesic Active Fields - A Geometric Framework for Image Registration

Jean-Philippe Thiran, Xavier Bresson, Dominique Zosso

In this paper we present a novel geometric framework called geodesic active fields for general image registration. In image registration, one looks for the underlying deformation field that best maps one image onto another. This is a classic ill-posed inve ...

Cadmium adsorption to mixtures of soil components: Testing the component additivity approach

Daniel Scott Alessi

The ability to predict the distribution of metals in geologic systems requires a modeling approach that can describe the competition among adsorbing surfaces for the metal of interest. In this study, we test if a component additivity (CA) surface complexat ...

Tribocorrosion of stainless steel in sulfuric acid: Identification of corrosion-wear components and effect of contact area

Electrochemical and friction measurements during unidirectional sliding tests are used to monitor and to evaluate the tribocorrosion behavior of a passivating material. Tribocorrosion is the interplay between chemical, electrochemical, and mechanical proce ...

Salt-Templated Mesoporous Solids Comprised of Interlinked Polyoxovanadate Clusters

Wendy Lee Queen

The utility of molten salts was demonstrated in the synthesis of the 1st family of mesoporous salt-inclusion solids featuring [V4O16] and [V5O17] polyoxovanadate (POV) units interlinked by As5+ cations, Cs3.5Na1.47(V5O9)(AsO4)2Cl2.33, Cs3.88Na0.12(V4.6O8.6 ...

Monocular 3D Reconstruction of Locally Textured Surfaces

Pascal Fua, Mathieu Salzmann, Appu Shaji, Aydin Varol

Most recent approaches to monocular non-rigid 3D shape recovery rely on exploiting point correspondences and work best when the whole surface is well-textured. The alternative is to rely either on contours or shading information, which has only been demons ...

Topography and work function measurements of thin MgO(001) films on Ag(001) by nc-AFM and KPFM

Marina Pivetta

The surface topography and local surface work function of ultrathin MgO(001) films on Ag(001) have been studied by noncontact atomic force microscopy (nc-AFM) and Kelvin probe force microscopy (KPFM). First principles calculations have been used to explain ...

Flame-assisted synthesis of nanoscale, amorphous and crystalline, spherical BiVO4 with visible-light photocatalytic activity

César Pulgarin, Nikola Castillo, Andre Heel

The synthesis of bismuth vanadate (BiVO4) nanoparticles has drawn considerable attention to their application as a visible-light-driven photocatalyst. Several techniques are addressing the enlargement of surface area, but some of them can cause impurities ...

Roombots-Towards Decentralized Reconfiguration with Self-Reconfiguring Modular Robotic Metamodules

Auke Ijspeert, Mikaël Mayer, Alexander Spröwitz, Rico Möckel, Stéphane Bonardi, Pierre-André Mudry, Philippe Laprade

This paper presents our work towards a decentralized reconfiguration strategy for self-reconfiguring modular robots, assembling furniture-like structures from Roombots metamodules. We explore how reconfiguration by locomotion from a configuration A to a co ...

Processing strategies for high-resolution GPR concrete inspections

Alexis Kalogeropoulos

A high-resolution multi-sensor and multi-polarization Ground Penetrating Radar (GPR) dataset was acquired on a concrete retaining wall. This dataset was characterised as a low pass filter with the help of a moving window spectral analysis. In order to exam ...
