Microbial Fuel Cells—Turning Waste into Energy: A membrane-free low-cost micrometer-sized microbial fuel cell is described in the Full Paper on page 648 by Muhammad M. Hussain and colleagues at King Abdullah University of Science and Technology. The cell was fabricated by using graphene as the anode and an air cathode to generate nanowatts of power. The graphene layer was grown on a nickel thin film by using chemical vapor deposition at atmospheric pressure. Microbial fuel cells harvest electrical energy produced by bacteria during the natural decomposition of organic matter, and this design is potentially useful for self-powered labs on chips and for rapid screening to scale up large-scale microbial fuel cells for water purification.
