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

The technology relates to an improved method for reclaiming waste beer from a brewing process. The process ensures the sterilization and re-use of beer that would otherwise be lost in the brewing process due to contamination. The method focuses on recovering beer lost in the fermentation stage
