Ionic Liquid Gating of SrTiO3 Lamellas Fabricated with a Focused Ion Beam

Amelia Emily-Kay Estry, Philip Johannes Walter Moll, Evgeny Mikheev

In this work, we combine two previously incompatible techniques for defining electronic devices: shaping three-dimensional crystals by focused ion beam (FIB), and two-dimensional electrostatic accumulation of charge carriers. The principal challenge for th ...

Tribological properties of gold matrix composite coatings with carbon nanocapsules containing ionic liquid lubricants

Stefano Mischler, Anna Neus Igual Muñoz

Self-lubricating, gold matrix composite coatings were produced by electrochemical codeposition of carbon nanocapsules filled with ionic liquid (IL) from a colloidal galvanic bath on a nickel electrode. The tribological response of the composite coatings wa ...

Oxide versus Nonoxide Cathode Materials for Aqueous Zn Batteries: An Insight into the Charge Storage Mechanism and Consequences Thereof

Alfredo Pasquarello, Assil Bouzid

Aqueous Zn-ion batteries, which are being proposed as large-scale energy storage solutions because of their unparalleled safety and cost advantage, are composed of a positive host (cathode) material, a metallic zinc anode, and a mildly acidic aqueous elect ...

Influence of Zinc Anisotropy on Solidification Microstructures: Experimental Results and Phase-Field Simulations

Alexandre Durussel

Due to a distortion of its hexagonal unit cell along the c-axis compared to hexagonal-close-packed metals (c/a = 1.856 instead of 1.633), zinc is characterised by a large anisotropy of its solid-liquid interfacial energy. While previous studies have focuse ...

Three-dimensional polymeric microtiles for optically-tracked fluidic self-assembly

Jürgen Brugger, Alcherio Martinoli, Massimo Mastrangeli

Self-assembly (SA) is a bio-inspired key coordination mechanism for swarms of intelligent agents as well as a pervasive bottom-up methodology for the fabrication of heterogeneous micro- and nanosystems. Analytical studies of SA at small scales are therefor ...

Adhesion of thermoplastic polyurethane elastomer to galvanized steel

Véronique Michaud, Basile Golaz

When a thermoplastic polyurethane elastomer (TPU) is co-molded with galvanized steel, the subsequent adhesion and its durability are very sensitive to the chemical bonds created at the interface. Silane coupling primers are known for enhancing adhesion bet ...

Scanning Tunneling Luminescence of Individual CdSe Nanowires

Klaus Kern, Marko Burghard, Zhe Wang, Theresa Lutz, Alexander Kabakchiev, Thomas Dufaux

The local luminescence properties of individual CdSe nanowires composed of segments of zinc blende and wurtzite crystal structures are investigated by low-temperature scanning tunneling luminescence spectroscopy. Light emission from the wires is achieved b ...

Adhesion of thermoplastic polyurethane elastomer onto galvanized steel

Véronique Michaud, Basile Golaz

When a thermoplastic polyurethane elastomer (TPU) is applied onto galvanized steel by a hot melt process, the subsequent adhesion and its durability are very sensitive to the chemical bonds created at the interface. The effects of several surface treatment ...

Texture Formation in Hot-Dip Galvanized Coatings : Nucleation and Growth of Anisotropic Grains in a Confined Geometry

Aurèle Mariaux

Continuous hot-dip galvanization is a process during which steel sheets are coated with a layer of Zn-Al alloy to protect them against corrosion. As the name indicates, this is achieved by dipping the preheated sheet into a bath of molten alloy. The sheet ...

Modeling Nucleation and Growth of Zinc Grains in Hot-Dip Galvanized Coatings

Michel Rappaz, Aurèle Mariaux

Hot-dip galvanized Zn-0.2wt%Al coatings on steel sheets exhibit a strong basal texture ({0001} parallel to the sheet plane). Part of this texture call be explained by the faster growth of < 10 (1) over bar0 > dendrites as compared with < 0001 >, granting b ...

Effect of HBP modified γ-APS on the coating toughness and practical adhesion between galvanised steel and polyethylene

Véronique Michaud, Xavier Bulliard, Gabrielle Pax

Epoxy-functionalised hyperbranched polymers (HBP) were combined with aminosilanes to form coatings and their effect on the practical adhesion between galvanised steel and polyethylene was investigated. It was shown that HBPs were initially soluble in silan ...

Tailoring of the practical adhesion between polyethylene and galvanised steel

Véronique Michaud, Gabrielle Pax

The practical adhesion of maleic anhydride grafted polyethylene (MAH-PE) to galvanised steel was studied using 3-point flexure tests, before and after hydrothermal ageing. Before bonding, the electro-galvanised steel was treated with γ -aminopropyltriethox ...
