The invention relates to a method of fabricating a commercially viable biodegradable and transparent resistive random-access memory (ReRAM) chip with substantially high (>7 orders of magnitude) resistive switching behaviour using low operating power. The method makes use of a simple and affordable...

Coarse particle transportation is essential for moving slurries, or fluids containing very high concentrations of pulverised solids, for example, hydraulic transport of coal ore or waste materials. Due to a scarcity of water and a high concentration of the solid particles, pipe blockages are common...
