OP22 Consideration and impact of advance directives on therapeutic decisions in ten intensive care units in german speaking switzerland
Autor: J Schefold, B Affolter, S Eychmüller
Publikováno v: Oral Presentations.
Background Since 2013 advance directives (AD) are binding in Switzerland. Regularly ICU doctors complain that they are not helpful for making therapeutic choices. But there is no data how often intensive care staff ask for advance directives at all a

Charge transfer at photoelectrochemical solar cells: a comparison of data from impedance and light-modulated spectroscopy
Autor: J. Schefold
Publikováno v: Journal of Electroanalytical Chemistry. 394:35-48
The impedance and the response to a light-modulated signal are compared at p-InP | V 3+ 2+ semiconductor |liquid junctions. The familiar recombination semicircle, seen in the complex-plane representation of the light-modulated response, is explained

Charge Transfer at Photoelectrochemical Solar Cells: Conclusions from the Open‐Circuit Impedance of p ‐ InP in V 3 + / 2 +
Autor: J. Schefold
Publikováno v: Journal of The Electrochemical Society. 142:850-862
Two resistance-capacitance (RC) time constants are detectable in the open-circuit impedance of illuminated (bare and Ag-treated) p-InP in contact with V{sup 3+/2+} + HCl solution. The dependence of the time constants on illumination intensity and con

The p-Inp semiconductor / electrolyte contact under depletion conditions: Impedance, reverse currents and photopotentials
Autor: J. Schefold
Publikováno v: Journal of Electroanalytical Chemistry. 362:97-108
Current—voltage and impedance spectroscopic measurements were made at the p-InP H2SO4 contact. Small reverse saturation current densities (ca. −1 nA cm−2) at low doped samples allowed measurement of the space-charge capacity Csc over more than

Publikováno v: Innovations in Fuel Cell Technologies ISBN: 9781849730334
Present global hydrogen demand is met to a large extent by fossil fuels. Hydrogen is produced via alkaline electrolysis of water only, when the required electric energy is readily available. Alternatively, hydrogen can be produced by water electrolys
