A linear magnetic field scan driver [PDF]
Concepts in Magnetic Resonance Part B: Magnetic Resonance Engineering, 2009 AbstractA linear magnetic field scan driver was developed to provide a rapidly scanning magnetic field for use in electron paramagnetic resonance (EPR) spectroscopy. The driver consists of two parts: a digitally synthesized ramp waveform generator and a power amplifier to drive the magnetic field coils.

Soft Microelectrode Linear Array for Scanning Electrochemical Microscopy [PDF]
Analytical Chemistry, 2010 A linear array of eight individual addressable microelectrodes has been developed in order to perform high-throughput scanning electrochemical microscopy (SECM) imaging of large sample areas in contact regime. Similar to previous reports, the soft microelectrode array was fabricated by ablating microchannels on a polyethylene terephthalate (PET) film ...
