The present work shows for the first time worldwide that sucrose can be easily placed by simple techniques within the micropores or nanostructure of the mercerized non-dried cotton linter fibers to create a low-cost cellulose substitute. Such sucrose

The suitability of rice straw for hardboard making was studied. Both the mechanical and semichemical pulping methods were investigated. It was found that addition of a relatively high amount of resin (2–3 %) is essential if hardboard—comparable t

Plant proteins are used – for the first time – in this work as bulk binders for cellulosic fibers in paper composites. Soy bean protein and wheat gluten were denatured by two methods, namely by: urea + NaOH and by urea + NaOH + acrylamide. Additi
