Optimisation of Collagen Films Produced via Pulsed Current Electrophoretic Deposition
… suppliers was compared when processed using pulsed current electrophoretic deposition (PC-EPD). It was found that, at voltages required for adequate yield (at least 5 V), formation of bubbles or corrosion of the electrode occurred for suspensions in aqueous media. However, dialysis of …

A unique electric discharge-excited solid state x-ray laser
A high-current discharge apparatus with a unique pulsed power supply was successfully constructed to demonstrate intense “anomalous” (exceeding direct charged-particle Bremsstrahlung) x-ray emission in the 1-2 keV range. Anomalous x-ray emission is attributed to ion implantation rather than normal …
