The comprehensive utilization of Si-rich biomass is restrained by macromolecular lignin and a large amount ash. In this study, rice husks (RHs) are treated as representative alkali extraction acid precipitation, the obtained lignin-SiO2 composite modified carbonazation, ball milling, magnesiothermic reduction additives. Through these processes, Si/C with excellent electrochemical properties per...

Citric acid is one of the important organic acids in fields industry, agriculture, medicine, etc., and it can be obtained many ways, best which biological methods using microorganisms. The current study aimed to prepare two cheap environmentally friendly culture media for purpose producing citric from Aspergillus niger. media, rice husks other Wheat bran, where a comparison was made between the...

Southeast Asia currently faces a huge increase in energy consumption and serious environmental issues. A widely underutilized still unexplored potential of these countries lies residual biomass. In the present research, production quantities yields most abundant agricultural byproducts Vietnam, i.e., rice straw, husks, sugarcane bagasse trash, were calculated. Total crop yield, residues ratio n...

Let X be a normal scheme and F a coherent sheaf on X . The reflexive hull or double dual of F is the sheaf F ∗∗ := HomX(HomX(F,OX),OX). The natural map F → F ∗∗ kills the torsion subsheaf of F and the support of coker[F → F ] has codimension ≥ 2. This establishes a functor from the category of coherent sheaves on X to the category of reflexive coherent sheaves on X . The same construction works...

The agro-processing industries can play a critical role in the development of sustainable and clean energy systems. lack knowledge about technical economic viability agro-waste to is major barrier successful implementation such systems developing countries, especially sub-Saharan Africa countries. This paper presents techno-economic-environmental assessment cluster rice mills located Abakaliki,...

Rice husks are a feedstock of biogenic silica because their high content. After extraction, solid residue comprising mostly carbohydrates is present. Solid valorization important for closed-loop systems using rice husk and has minimal negative environmental impacts. In this study, we used that was generated by extractionto anaerobic digestion producing biomethane. The characterized in terms tot...
