Comparison of apparent activation energies for densification of alumina powders by pulsed electric current sintering (spark plasma sintering) and conventional sintering-toward applications for transparent polycrystalline alumina

Paul Bowen, Michael Stuer, Zhe Zhao, Claude Paul Carry

In the quest for high real in-line transmittances for transparent polycrystalline alumina (PCA), we need defect free processing. One of the biggest advances in producing high density defect free ceramics over recent years has been the advent of spark plasm ...

Morphology, structural and optical properties of iron oxide thin film photoanodes in photoelectrochemical cell: Effect of electrochemical oxidation

Artur Braun, Yelin Hu

Hematite (alpha-Fe2O3) is a promising semiconductor as photoanode in solar hydrogen production from photoelectrolysis of water due to its appropriate band gap, low cost and high electrochemical stability in aqueous caustic electrolytes. Operation of such p ...

Influence of calcium to silica ratio on aluminium uptake in calcium silicate hydrate

Karen Scrivener, Barbara Lothenbach, Émilie Michèle L'Hôpital

Aluminium uptake in calcium silicate hydrate (C-S-H) was studied at different Ca/Si ratios from 0.6 to 1.6 at 20 degrees C. Aluminium incorporation in C-S-H depends on the total amount of aluminium present in the sample. At low Al/Si ratio (

Solutions for thermally mismatched brazing operations for ceramic tokamak magnetic sensor

Duccio Testa, Peter Ryser, Matthieu Toussaint, Thomas Maeder, Caroline Jacq, Philipp Windischhofer, Xinyue Jiang

To monitor high-frequency fluctuations of the equilibrium magnetic field in tokamaks, a 3D magnetic sensor has been developed. The sensor, which is positioned inside the vacuum vessel behind the protective tiles of the tokamak and is exposed to potential t ...

Targeted design of alpha-MnO2 based catalysts for oxygen reduction

Michael Markus Busch

The paper focuses on theoretical and experimental aspects of an oxide surface optimization for oxygen reduction reaction (ORR). Various doped alpha-MnO2 based electrocatalysts were prepared by microwave-assisted hydrothermal synthesis and electrochemically ...

Suspended micro resonator fabrication: atomic layer deposition

Annalisa De Pastina, Mathieu Basile Aberle

This project is focused on atomic layer deposition of aluminium oxide to fabricate suspended microchannel resonators. Few examples of the applications of such devices are blood analysis to detect cancerous cells or device cooling directly on the chip. The ...

Preliminary Assessment Of Durability Of A Low Carbon Concrete Made With Limestone Calcined Clay Portland Cement

Through a collaborative research effort between the Ecole Polytechnique Federal de Lausanne and CIDEM a new kind of cementitious binder has been developed based on the synergy between calcined clays and limestone. Industrial trials carried out in Cuba duri ...

Sensing the quantum limit in scanning tunnelling spectroscopy

Klaus Kern, Markus Etzkorn, Matthias Alexander Eltschka, Jacob Senkpiel

The tunnelling current in scanning tunnelling spectroscopy (STS) is typically and often implicitly modelled by a continuous and homogeneous charge flow. If the charging energy of a single-charge quantum sufficiently exceeds the thermal energy, however, the ...
