Integration of MOX gas sensors on polyimide hotplates

Nico de Rooij, Danick Briand, Jérôme Courbat

In this communication, we report on the integration of metal-oxide gas sensors on polymeric micro-hotplates made on polyimide and silicon substrates. Low-power consumption micro-hotplates with platinum electrodes and heaters were fabricated on polyimide me ...

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 ...

Formation of Metal Nano- and Micro-patterns on Self-Assembled Monolayers Using Pulsed Laser Deposition through Nanostencils and Electroless Deposition

Jürgen Brugger, Marc Antonius Friedrich van den Boogaart

Patterns of noble-metal structures on top of self-assembled monolayers (SAMs) on Au and SiO2 substrates have been prepared following two approaches. The first approach consists of pulsed laser deposition (PLD) of Pt, Pd, Au, or Cu through nano- and microst ...

Metal and metaloxide nanostructures on and in plant viruses

Sinan Balci

Tobacco Mosaic Virus (TMV) is composed of 2130 identical coat protein subunits following the right-handed helix of an accompanying RNA strand to produce a 300 nm hollow cylinder with an outer diameter of 18 nm and a 4 nm wide central channel. In this work, ...

Partial release and detachment of microfabricated metal and polymer structures by anodic metal dissolution

Philippe Renaud, Arnaud Bertsch, Stefan Metz

The large majority of microelectromechanical systems (MEMS) are fabricated on silicon, glass or Pyrex substrates by manufacturing techniques, which originated from the semiconductors industry. However, their final application often requires removal of the ...

Electrochemical promotion of ethylene oxidation over Rh catalyst thin films sputtered on YSZ and TiO2/YSZ supports

Christos Comninellis, György Foti

The effect of electrochem. promotion of catalysis or nonfaradaic electrochem. modification of catalytic activity or electropromotion was studied for the model reaction of ethylene oxidn. on sputter-coated Rh films. The thin (40 nm) Rh films were deposited ...
