Parylene C Coated Microelectrodes For Scanning Electrochemical Microscopy

Hubert Girault, Pekka Eero Peljo, Fernando Cortes Salazar, Haiqiang Deng, Carlos Manuel De Melo Pereira

Herein, we present a simple microelectrode preparation methodology consisting in coating a platinum wire or a carbon fiber with a thin insulating Parylene C film (e.g. 1–10 μm), to produce SECM probes with a small and constant probe RG (i.e. ratio between ...

Soft Stylus Probes for Scanning Electrochemical Microscopy

Hubert Girault, Fernando Cortes Salazar, Anne-Laure Gassner, Gunther Wittstock, Mohamad Hojeij

A soft stylus microelectrode probe has been developed to carry out scanning electrochemical microscopy (SECM) of rough, tilted, and large substrates in contact mode. It is fabricated by first ablating a microchannel in a polyethylene terephthalate thin fil ...

FEM-MILL: a finite element based 3D transient milling simulation environment for process plan verification and optimization

Jitender Kumar Rai

The rigid body motion of thin walled parts and their elastic-plastic deformations induced during high speed milling are the main root causes of part geometrical and dimensional variabilities; these are governed mainly from the choice of process plan parame ...
