Sugar palm (Arenga pinnata) fibre (SPF) waste is a side product of sugar starch production and needs to be processed avoid environmental pollution. Since the SPF has high cellulose content, it can beneficial if valorized into high-value products such as nanocrystal (CNC). The CNC from was initiated by using an environmentally friendly peroxide bleaching elementary chlorine free method. conducte...

The reaction of nano-cellulose and antimony pentachloridein dichloromethane gave nano-cellulose-SbCl5. Also nano-cellulose-SbCl5 has beencharacterized by energy dispersive X-ray spectroscopy(EDX), scanning electron microscopy (SEM)and Fourier transform infrared spectroscopy(FTIR).Nano-cellulose-SbCl5has been applied as a nano-catalyst for synthesis of pyrano[2,3-d]pyrimidines from the simple on...

Cellulose nanofibers (CNF) are materials synthesized from wood-based fibers having excellent mechanical properties due to their high crystallinity. In this research, the cellulose were bamboo fibers, as abundant natural available worldwide. The had been using chemical processes of bleaching with acetic acid and sodium chloride, followed by alkaline treatment hydroxide, hydrolysis sulfuric combi...

A silica supported sulfuric acid catalyzed [3+2] cycloaddition of nitriles and sodium azide to form 5-substituted 1H-tetrazoles is described. The protocol can provide a series of 5-substituted 1H-tetrazoles using silica sulfuric acid from nitriles and sodium azide in DMF in 72%-95% yield.

The electrical property of aqueous sulfuric acid has been studied by the first-principles molecular dynamics simulation. The calculated conductivity of aqueous sulfuric acid solution from our simulation is 0.33 S/cm, which agrees reasonably with an experimental value. This implies the applicability of the method used in this study for electrochemical systems.

The aim of this study was to evaluate the effects of adding sulfuric acid to sugarcane tops silage on rumen bacteria and whole rumen microorganisms (WRM) and compare the digestibility of sugarcane tops treated with different amount of urea, molasses and sulfuric acid between Holstein cow and Khouzestan buffalo. Regardless of the type of the treatment, potential of gas production (B) by cow WRM ...

The complete hydrolysis of konjac glucomannan (KGM) with an acid or enzyme generally takes a long time. To accelerate KGM hydrolysis without diminishing the conventional quality, a diluted acid hydrolysis of KGM with sulfuric acid was conducted using a microwave digestion system. The optimum conditions of microwave-assisted acid hydrolysis for KGM were: 10 mL of 0.25 M sulfuric acid, hydrolysis...

Biofuels, like biobutanol, have been recognized for being renewable and sustainable fuels which can be produced from lignocellulosic biomass. To convert lignocellulosic biomass to biofuel, pretreatment process is an important step to remove hemicelluloses and lignin to improve enzymatic hydrolysis. Dilute acid pretreatment has been successful developed for pretreatment of corncobs and the optim...
