Ligand-mediated formation of Cu/metal oxide hybrid nanocrystals with tunable number of interfaces

Raffaella Buonsanti, Jan Vávra, Dragos-Constantin Stoian, James Richard Pankhurst, Seyedehbehnaz Varandili

Combining domains of different chemical nature within the same hybrid material through the formation of heterojunctions provides the opportunity to exploit the properties of each individual component within the same nano-object; furthermore, new synergisti ...

Deposition of Thin Alumina Films Containing 3D Ordered Network of Nanopores on Porous Substrates

Martina Lihter

Self-supporting thin films containing nanopores are very promising materials for use for multiple applications, especially in nanofiltration. Here, we present a method for the production of nanomembranes containing a 3D ordered network of nanopores in an a ...

Recycled Glass Fiber Composites from Wind Turbine Waste for 3D Printing Feedstock: Effects of Fiber Content and Interface on Mechanical Performance

Rodolphe Henri

This research validates the viability of a recycling and reusing process for end-of-life glass fiber reinforced wind turbine blades. Short glass fibers from scrap turbine blades are reclaimed and mixed with polylactic acid (PLA) through a double extrusion ...

Crushing and intrusion resistance improvement of aluminum beams by carbon/epoxy composite patches

Véronique Michaud, Baris Çaglar, Jonathan Friedli, Yann Albert Gérard Lebaupin

This study investigates the intrusion and crushing performance of hybrid fiber metal laminates based on aluminum and carbon fiber reinforced polymers, in comparison to reference aluminum parts, made from AA6451 or AA7075 automotive grade alloys. A first se ...

Effect of cooling conditions on microstructures and mechanical behaviors of reheated low-carbon weld metals

Roland Logé, Cyril Cayron

An investigation was conducted to systematically explore the relationships among microstructure evolution, continuous cooling transformation kinetics, and mechanical properties development in a low-carbon reheated weld metal (0.052C-1.5Mn-0.3Si-0.7Cr-0.8Mo ...

Impact of in situ nanomechanics on physical metallurgy

Johann Michler, Helena Van Swygenhoven

The mechanical response of modern alloys results from a complex interplay between existing microstructure and its evolution with time under stress. To unravel these processes, in situ approaches intrinsically have a critical advantage to explore the basic ...

Shear in reinforced concrete without transverse reinforcement : from refined experimental measurements to mechanical models

Francesco Cavagnis

Since the first applications of structural concrete, the shear behaviour of one-way slabs without transverse reinforcement has been largely investigated. Nevertheless, currently in the scientific community there is no general agreement on the mechanisms of ...

Experimental investigation of multi-span post-tensioned glass beams

Alain Nussbaumer, Pieter Christian Louter, Jagoda Cupac

This paper presents a study on post-tensioned glass beams in a statically indeterminate system. In order to increase the safety of structural glass beams, ductile reinforcement can be added to glass beam sections providing secondary load carrying mechanism ...

Effect of interfacial interactions on the electromechanical response of poly(vinylidene fluoride-trifluoroethylene)/BaTiO3 composites and its time dependence after poling

Jan-Anders Edvin Maansson, Véronique Michaud, Yves Leterrier, Dragan Damjanovic, Sara Dalle Vacche

Solvent cast and compression molded composite films based on poly(vinylidene fluoride-trifluoroethylene), containing pristine and silylated BaTiO3 particles, were poled, and their electromechanical response (d(33)), their dielectric properties, and the cry ...

The origin of the pozzolanic activity of calcined clay minerals: A comparison between kaolinite, illite and montmorillonite

Karen Scrivener

This paper investigates the decomposition of three clayey structures (kaolinite, illite and montmorillonite) when thermally treated at 600 degrees C and 800 degrees C and the effect of this treatment on their pozzolanic activity in cementitious materials. ...

A mesoscale granular model for the mechanical behavior of alloys during solidification

Michel Rappaz, Stéphane Vernède

We present a two-dimensional granular model for the mechanical behavior of an ensemble of globular grains during solidification. The grain structure is produced by a Voronoi tessellation based on an array of predefined nuclei. We consider the fluid flow ca ...

Enhanced safety with post-installed punching shear reinforcement

Aurelio Muttoni, Miguel Fernández Ruiz

A considerable number of flat slabs supported by columns need to be strengthened against punching shear. Reasons are increasing loads, construction or design errors, but also more stringent code requirements due to the increased knowledge gained in the pas ...

Carbon nanofibers grown on metallic filters as novel catalytic materials

Lioubov Kiwi, Pascal Tribolet

Carbon nanofibers (CNF) were synthesized on sintered metal fibers (SMF) filters of nickel and Ni-containing alloys (Inconel, stainless steel (SS)) by thermal chemical vapor deposition of ethane in the presence of hydrogen at not, vert, similar660 °C. The C ...
