Cellulose nanocrystals (CNCs) using different cellulose polymorphs have been fabricated from raw bamboo pulp. Their structural and morphological effects on the mechanical, barrier thermal properties of poly(lactic acid) investigated.
This article reports the fabrication of poly (3-hydroxybutyrate) (PHB)/cellulose nanocrystal (CNC) based nanobiocomposite films with improved gas barrier and migration properties for food packaging applications. Acid hydrolysis cellulose pulp from bamboo (Bambusabalcooa) yields CNCs diameter 15–20 nm length 400–600 nm. Evaluation d-spacing using XRD indicates intercalation PHB matrix CNC at optimum loadings 2 wt%. Overall values in presence both polar nonpolar simulants are found within...
This paper reports a single-step co-precipitation method for the fabrication of magnetic cellulose nanocrystals (MGCNCs) with high iron oxide nanoparticle content (∼51 wt % loading) adsorbed onto (CNCs). X-ray diffraction (XRD), Fourier transform infrared (FTIR), and Raman spectroscopic studies confirmed that hydroxyl groups on surface CNCs (derived from bamboo pulp) acted as anchor points adsorption Fe3O4 nanoparticles. The fabricated MGCNCs have moment, which is utilized to orient...
In this study, we successfully demonstrate single-step industrially scalable reactive extrusion of polylactic acid (PLA)/cellulose nanocrystal (CNC)-based cast films which leads to reduced necking, improved processability, melt strength, and rheological behavior. PLA chains grafted onto CNCs, formed cross-linked gel-like structures high molecular weight (Mw ≈ 150–245 kDa), with varying grafting efficiency (14%–67%) or gel-fraction yield (16%–69%), depending on the type compatibilizers used....
ABSTRACT This study explores the plasticizing effect of coconut oil (CO) on PLA for evaluating its suitability flexible packaging. Changes in morphological, mechanical, thermal, rheological, barrier and optical properties melt compounded Poly(lactic acid)–Coconut (PLA–CO) blend were investigated by varying mixing ratio. Water vapor permeability blends decreased 58% at 7 wt % plasticizer content. The tensile strength showed a decreasing trend with increasing percentage while elongation an...
The increasing global concern for sustainability in supply chain management is driven by stricter government regulations addressing environmental pollution and social injustice. This has led to a growing emphasis on integrating into practices. However, there limited research incorporating all three dimensions of (economic, environmental, social) management. study presents mixed-integer linear programming model designing an uncertain network design that aims minimize overall costs...
Separation of CO2 from gas mixtures is importance in capture flue and natural sweetening. In this paper, we have conducted grand canonical Monte Carlo (GCMC) simulations to study the adsorption CO2, N2, CH4 separation their binary mesoporous silica MCM-41 modified by incorporation pyrrolidinium-based ionic liquid 1-methyl-1-butyl-pyrrolidinium bis(trifluoromethanesulfonyl)imide ([C4PYR]+[TF2N]−) at two different loadings: ∼21 42% weight, hereinafter referred as MCM-41-IL1 MCM-41-IL2,...
Graphene nanoscrolls (GNS), due to their remarkably interesting properties, have attracted significant interest with applications in various engineering sectors. However, uncontrolled morphologies, poor yield and low quality GNS produced through traditional routes are major challenges associated. We demonstrate sustainable approach of utilizing bio-derived cellulose nanocrystals (CNCs) as template for fabrication tunable morphological dimensions ranging from micron-to-nanoscale(controlled...
Abstract The current work investigates various bimetallic catalysts supported on Al 2 O 3 −Zn−ZrO to determine a catalyst with minimal CO selectivity at high temperature for methanol steam reforming. Characterization tools employed in this study include programmed reduction, X‐ray diffraction, photoelectron spectroscopy and transmission electron microscopy. Activity testing all the synthesized were performed range of 150 500 °C. Bimetallic addition Fe as second metal Cu 50 : molar ratio was...
