Abstract:
Bioconversion of lignocellulose to fermentable sugars is a promising approach to produce potential bio-based energy and chemicals. Pretreatment is the key step to remove or delocalize lignin in lignocellulose, thus improving enzymatic saccharificatio...

Abstract:
This study investigates the effects of storage time on fuel properties of biodiesel made from Jatropha oil and its blends with mineral diesel at different percentage compositions. The influence of storage stability on selected fuel properties such as...

Abstract:
Properties of gelatin composite films(with 4% glycerol as plasticizer) with different mass concentrations of microfibrillated cellulose (MFC) (0.2-1.0%) were investigated. The prepared composite films with 1.0% MFC showed the highest tensile strength...

Abstract:
The pulp and paper industry produces a large amount of colored effluent in the pulping, bleaching, and papermaking processes. The wastewater from the pulp washing and bleaching stages is also known as mid-stage pulping effluent, which is difficult to...

Abstract:
Chitosan/montmorillonite nanocomposites can impart water vapor and oxygen barrier and antimicrobial properties to paper. However, this application is limited by the low water-solubility of chitosan. Carboxymethylation can increase the water-solubilit...
