Oxygen Plasma/Bismuth Modified Inkjet Printed Graphene Electrode for the Sensitive Simultaneous Detection of Lead and Cadmium

Hubert Girault, Andreas Stephan Lesch, Milica Jovic, Victor Costa Bassetto

In this work, a simple procedure for the preparation of an inkjet printed disposable graphene electrode is reported. Commercial graphene ink was printed on a kapton substrate and the resulting electrode was 30 min treated by oxygen plasma, then modified by ...

A Redox-Flow Electrochromic Window

Michael Graetzel, Shaik Mohammed Zakeeruddin

A low-cost electrochromic (EC) window based on a redox-flow system that does not require expensive transparent conductive oxide (TCO) substrates is introduced and demonstrated for the first time. An aqueous I-3/I redox electrolyte is used in place of a TCO ...
