Neodymium-deficient nickelate oxide Nd1.95NiO4+ı as cathode material for anode-supported intermediate temperature solid oxide fuel cells

The neodymium-deficient nickelate Nd1.95NiO4+ı, mixed conducting K2NiF4-type oxide, was evaluated as cathode for solid oxide fuel cells. The electrochemical properties were investigated on planar Ni–YSZ anode-supported SOFC based on co-tape casted and co-f ...

New Efficiency Records for Stable Dye-Sensitized Solar Cells with Low-Volatility and Ionic Liquid Electrolytes

Michael Graetzel, Shaik Mohammed Zakeeruddin, Peng Wang, Nuttapol Pootrakulchote, Jin Guo

We report a high molar extinction coefficient heteroleptic polypyridyl ruthenium sensitizer, featuring an electron-rich 3,4-ethylenedioxythiophene unit in its ancillary ligand. A nanocrystalline titania film stained with this sensitizer shows an improved o ...

An Integrated Adaptive Model for Overheating Risk Prediction

Darren Robinson, Frédéric Haldi

Based on results from a field survey campaign, this paper describes three new developments which have been integrated to provide for a comprehensive basis for the evaluation of overheating risk in offices. Firstly, a set of logistic regression equations ha ...

Common-mode Oscillation in Capacitive Coupled Differential Colpitts Oscillators

Christian Enz, Uroschanit Yodprasit

A simple approach to the realisation of a differential Colpitts oscillator is to connect the grounded capacitor in the feedback network of two single-ended Colpitts oscillators together in series. As the output signals are expected to be differential, it i ...

Multistacked Al2O3∕HfO2∕SiO2 tunnel layer for high-density nonvolatile memory application

Wei Chen

A memory capacitor with a multistacked tunnel layer of Al2O3/HfO2/SiO2 (AHO) has been fabricated together with HfO2 charge trapping layer and Al2O3 control oxide layer. The resulting capacitor exhibits a memory window as large as 7.6 V for +/- 12 V sweep v ...

Anode dusting during the electrolytic production of aluminium

Timea Tordai

The disintegration of the carbon anodes during the electrolysis of alumina produces dust particles contaminating the electrolytic bath. This phenomenon, called dusting, is one of the most deleterious Al electrolysis failures, as it leads to a significant d ...

Design of simulator for seepage detection in an embankment based on distributed optic fibre sensing technology

Luc Thévenaz, Pingyu Zhu, Yang Zhou

Based on the temperature change in an embankment, a seepage flow simulator and monitoring system based on distributed optical fiber sensing are proposed. A simulator is designed that consists of scale model of embankment with definite length, seepage flow ...

Metallic bundles of single-wall carbon nanotubes probed by electron spin resonance

László Forró, Bálint Náfrádi

C59N magnetic fullerenes inside single-wall carbon nanotubes (SWCNTs) are used to probe the density of states (DOS) on the host tubes using electron spin resonance (ESR). The C59N radicals are separated by C60 fullerenes to prevent dimerization and C59N-C6 ...
