    Abstract: Urea formaldehyde resin is an end-stage thermosetting resin in which urea and formaldehyde are polycondensated into an initial urea formaldehyde resin under the action of alkaline or acidic catalyst, and then an insoluble and non-fusible resin is formed under the action of curing agent or additives. Urea formaldehyde resin has the characteristics o... Show More

    Abstract: Charcoal is a light-weight black carbon residue produced by strongly heating wood with minimal oxygen to remove all water and volatile constituents. Jute sticks were used as a cheap precursor for the preparation of charcoal and activated carbon. Chemical activation with CaCl2 caused the physicochemical changes in charcoal. Jute sticks were carboniz... Show More
