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

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 ...

Controlling Mesopore Size and Processability of Transparent Enzyme-Loaded Silica Films for Biosensing Applications

Heinrich Hofmann, Oswaldo Javier Pérez Anguiano, Bernard Wenger, Raphaël Pugin, Emmanuel Scolan

Silica-based nanoporous thin films including large mesopores are relevant as enzyme supports for applications in biosensing. The diffusion and immobilization of large biomolecules such as enzymes in such porous films require the presence of large mesopores ...

Mesoscopic Modeling and Experimental Investigations of the Last-Stage Solidification of Globular-Equiaxed Grains in Metallic Alloys

Christophe Mondoux

Hot tearing is a major defect of solidification processes and welding. It occurs in metallic alloys while they are in the semi-solid state and is caused by a lack of liquid feeding in the mushy zone to compensate solid network openings due to tensile and s ...

Surface 3D Micro Free Forms: Multifunctional Microstructured Mesoporous alpha-Alumina by in Situ Slip Casting Using Excimer Laser Ablated Polycarbonate Molds

Paul Bowen, Patrik Willi Hoffmann, Sriharitha Rowthu

Ceramic surface microstructuring is a rapidly growing field with a variety of applications in tribology, wetting, biology, and so on. However, there are limitations to large-area microstructuring and fabrication of three-dimensional (3D) micro free forms. ...

Effect of Cavity Lifetime Variation on the Static and Dynamic Properties of 1.3-μm Wafer-Fused VCSELs

Elyahou Kapon, Alexandru Mereuta, Vladimir Iakovlev, Alexei Sirbu, Andrei Caliman, Zlatko Mickovic, Dalila Ellafi

We investigate experimentally the impact of photon cavity lifetime variations on the static and dynamic performance of high-speed 1.3-mu m wavelength wafer-fused vertical-cavity surface-emitting lasers (VCSELs). The photon lifetime is modified by decreasin ...

Preliminary studies on the mechanical behaviour of thick embedded laminated connections

Pieter Christian Louter, Manuel Santarsiero

Laminated glass components are usually realized bonding glass plates by means of interlayer polymers that develop adhesion forces during lamination. Recently, these adhesion forces have been used also to realize adhesive connections for structural glass co ...

Effect of load history on punching shear resistance of flat slabs

Thomas Keller, Robert Koppitz

The unloading of reinforced concrete slabs results in residual slab rotations and reloading to the same load results in irreversible rotation increases. Unloading and reloading (UR) cycles applied to non-strengthened and strengthened flat slabs may thus af ...

In situ Neutron Diffraction during Casting: Determination of Rigidity Point in Grain Refined Al-Cu Alloys

Jean-Marie Drezet, Bastien Gilbert Pierre Mireux

The rigidity temperature of a solidifying alloy is the temperature at which the solid plus liquid phases are sufficiently coalesced to transmit long range tensile strains and stresses. It determines the point at which thermally induced deformations start t ...
