This work presents an experimental holistic approach for the design of a continuous catalytic conversion process of carbohydrates derived from waste biomass to 5-hydroxymethylfurfural (5-HMF) using a tin-doped active carbon catalyst. In this report, apple biomass waste is used as a model component as …

Sustainable ammonia colorimetric sensors made from bio-based compounds prepared from agricultural waste are developed. The sensors operate at room temperature at two important concentration scales: an accident scale (>50 ppm NH3 in the air) and a health and safety scale (1 ppm – 50 ppm NH3 in the air). …
