Pulverization and corrosion studies of bare and cobalt-encapsulated metal hydride electrodes

Electrochemical impedance spectroscopy was used as an in situ technique to determine the average particle size of metal hydride electrodes. Using this, the pulverization of bare and cobalt-encapsulated LaNi Sn alloy was studied as a function of charge–dis4.27 0.24 charge cycles. In the case of bare alloy, pulverization causes an exponential decay in particle size with cycling. Cobalt-encapsulat...

Transparent and Stretchable Metal Electrodes

Thin layers of lamellar-forming polystyrene-block-poly (methyl-methacrylate) (PS-b-PMMA) provide the templates for fabricating nanowires with a “fingerprint” morphology. The electrical characteristics of the nanowires were measured, and largely deviated from simulated devices due to high defect density. Their highly curved conformation makes the nanowires strong candidates for electrical testin...

On-chip metal/polypyrrole quasi-reference electrodes for robust ISFET operation.

To operate an ion-sensitive field-effect transistor (ISFETs) it is necessary to set the electrolyte potential using a reference electrode. Conventional reference electrodes are bulky, fragile, and too big for applications where the electrolyte volume is small. Several researchers have proposed tackling this issue using a solid-state planar micro-reference electrode or a reference field-effect t...
