Piezoresistive effect in epoxy–graphite composites

In this work, we investigate the piezoresistive response of epoxy–graphite composites. A resistive thick-film Wheatstone bridge is deposited by screen-printing onto a beam, a weight is then applied on the tip of the beam and the resulting electrical signal ...

Numerical analysis of a reciprocating active magnetic regenerator made of gadolinium wires

Didier Albert Simon Vuarnoz

During the last century, the MagnetoCaloric Effect (MCE) has been widely used for realizing extremely low temperatures. However, it is only in the last three decades that some of the efforts to develop a benign and cutting-edge technology for realizing the ...

Borophosphonate Cages: Easily Accessible and Constitutionally Dynamic Heterocubane Scaffolds

Rosario Scopelliti, Kay Severin, Laure Menin, Konstantin Zhurov, Justus Tönnemann

A versatile and experimentally facile procedure for the synthesis of borophosphonate cages of the general formula [tBuPO3BR′]4 is described. The method involves heating of tert-butylphosphonic acid with a boronic acid in toluene to give borophosphonates in ...

Exploiting the Divergent Reactivity of Isocyanoacetates: One-Pot Three-Component Synthesis of Functionalized Angular Furoquinolines

Jieping Zhu

A one-pot, three-component synthesis of polysubstituted furo[2,3-c] quinoline 1 was developed based on the new reactivity profile of alpha-(4-nitrophenyl)-alpha-isocyanoacetates. Simply mixing aldehydes 2, ortho-alkynylanilines 3, and alpha-(4-nitrophenyl) ...

Plasma Jet-Substrate Interaction in Low Pressure Plasma Spray-CVD Processes

Christoph Hollenstein, Philippe Frédérique Bruno Guittienne, Malko Gindrat

Conventional equipment for plasma spraying can be adapted for operation at low pressure so that PECVD-like processing can be performed. The plasma jet generated by the torch is characterized by a high convective velocity and a high gas temperature. The inf ...

TaOxNy Sputtered Photoanodes For Solar Water Splitting

Michael Graetzel, Kevin Sivula, Vincent Laporte, Rosendo Sanjines, Nicolas Xanthopoulos, Maurin Cornuz

A series of TaOxNy photoelectrodes were deposited on F:SnO2 (FTO) substrates by DC reactive sputtering at room temperature, under a mixture of Ar, N-2 and O-2. The effects of the O-2 partial pressure during deposition (Po-2) on the films crystallinity, the ...

Atomic-scale engineering of magnetic anisotropy of nanostructures through interfaces and interlines

Harald Brune, Stefano Rusponi, Philipp Buluschek, Sergio Vlaic, Géraud Moulas

The central goals of nanoscale magnetic materials science are the self-assembly of the smallest structure exhibiting ferromagnetic hysteresis at room temperature, and the assembly of these structures into the highest density patterns. The focus has been on ...

A simplified GaN/AlGaN quantum cascade detector with an alloy extractor

Nicolas Grandjean, Etienne François Olivier Giraud

We have demonstrated a GaN/AlGaN quantum cascade detector based on a simplified design of the extractor region relying on an AlGaN thick layer. The device grown by molecular beam epitaxy exhibits both TM-polarized intersubband absorption and photocurrent a ...

Phosphorescent cationic iridium(III) complexes with cyclometalating 1H-indazole and 2H-[1,2,3]-triazole ligands

Michael Graetzel, Mohammad Khaja Nazeeruddin, Rosario Scopelliti

Two new cationic iridium(III) complexes with cyclometalating 1-phenylindazole or 2-phenyl-1,2,3-triazole ligands, (C boolean AND N)(2)Ir(4,4'-di-tert-butyl-2,2'-dipyridyl), exhibit yellow or green phosphorescence with quantum yields and excited stat ...

Experimental and numerical characterisation of heat flow during flame cutting of thick steel plates

Jean-Paul Lebet, Raphaël Thiébaud

This paper concentrates on the characterization of the heat flow present during flame cutting of 60 mm thick steel (S355N) flanges, a typical size used in the fabrication of bridge girders. Experimental results are associated with a finite element analysis ...
