Waste Coffee Ground Biochar: A Material for Humidity Sensors

Waste Coffee Ground Biochar: A Material for Humidity Sensors

Worldwide consumption of coffee exceeds 11 billion tons/year. Used coffee grounds end up as landfill. However, the unique structural properties of its porous surface make coffee grounds popular for the adsorption of gaseous molecules. In the present work, we demonstrate the use of coffee grounds as...
