A cellulose derivative substance called acetate is frequently used in the manufacturing of photographic film, fiber, membranes, and bioplastics. However, availability sources for acetate's raw material does not support this demand. Paper waste has a high content. Therefore, aim research to synthesize from α-cellulose paper. In order separate alpha paper study, delignification process with NaOH ...

BACKGROUND More than 90% of the cigarettes sold worldwide have a filter. Nearly all filters consist of a rod of numerous ( > 12 000) plastic-like cellulose acetate fibres. During high speed cigarette manufacturing procedures, fragments of cellulose acetate that form the mouthpiece of a filter rod become separated from the filter at the end face. The cut surface of the filter of nearly all cigar...

To develop bio-packaging materials, nanocomposite films of cellulose acetate reinforced with titanium dioxide and zinc oxide nanoparticles were prepared, by the casting method at different weight ratios ZnO (1.5, 2, 2.5) wt% a constant ratio 2 TiO2. TiO2 tested using scanning electron microscopy (SEM). The mechanical properties (tensile strength elongation) improved fixed level Cellulose Acetat...

Carbon dioxide (CO2) release from the exhaust gas streams of power plants that burn fossil fuels contributes the most emission of this gas, which includes more than half of the greenhouse effects. Thus, the separation of CO2 from exhaust gases is one of the main environmental concerns. Membrane technology, due to many advantages, has attracted many research attentions among the various gas sepa...

The metatranscriptomic recharacterization in the present study captured microbial enzymes at the unprecedented scale of 40,000 active genes belonged to 2,269 KEGG functions were identified. The novel information obtained herein revealed interesting patterns and provides an initial transcriptional insight into the thermophilic cellulose methanization process. Synergistic beta-sugar consumption b...

The metabolic characteristics of Clostridium cellulolyticum, a mesophilic cellulolytic nonruminal bacterium, were investigated and characterized kinetically for the fermentation of cellulose by using chemostat culture analysis. Since with C. cellulolyticum (i) the ATP/ADP ratio is lower than 1, (ii) the production of lactate at low specific growth rate (mu) is low, and (iii) there is a decrease...

Abstract Composite nanoparticles (NPs) consisting of lignin and different polysaccharide (PS) derivatives were prepared. In this synergistic approach, the PS derivative acts as biocompatible matrix that forms spherical NPs while is a functional compound with therapeutic potential (e.g., antioxidative, antimicrobial, antiviral). Organosolv three (cellulose acetate/CA, cellulose acetate phthalate...

Abstract Cellulose mixed esters (CMEs) substituted with two different types of acyl groups are promising polymeric materials various tunable properties but arduous to produce. This is because the insolubility cellulose in common solvents, and thus, industrial production CMEs desired degrees substitution (DSs) requires a costly multistep process. To accomplish their facile production, homogeneou...
