ABSTRACT Water pollution by organic pollutants is a continuous and increasing problem of global concern. In this paper, we developed nanocrystalline cellulose (NCC) titania (TiO2) based nanocomposite for the photocatalytic degradation o-chloranil via aqueous wet impregnation. Different NCC loadings (10, 20, 40, 80%) were used, several analytical microscopy techniques characterised NCC/TiO2 cata...

Although it has been proven that porous, heteroatomic, and defective structures improve Na storage performance, they also severely affect the initial Coulombic efficiency (ICE) due to huge irreversible capacity in first cycle, which always limits practical application of carbon anodes commercial Na-ion batteries (NIBs). Here, we show successful synthesis nanocrystalline cellulose derivative har...

This study aims to determine the effect of nanocrystalline cellulose and potassium chloride (KCl) bioplastics from avocado seed starch glycerol as plasticizer. In this study, nanocrystal obtained palm fruit fiber was hydrolyzed using sulfuric acid (H2SO4) at a concentration 50%. The used in extraction process. On producing bioplastic, casting method with addition filler 1%, 2%, 3%, 4% (%w), KCl...

The present work focuses on development and investigation of new functional hybrid nanomaterials based on titania nanoparticles and cellulose, possessing an important set of practical properties. The study includes two parts: first, nanocrystalline TiO2 hydrosols produced by low-temperature sol-gel synthesis were successfully applied for cotton fabric modification. Comprehensive characterizatio...

We report transmission electron microscope observations that provide evidence of deformation twinning in plastically deformed nanocrystalline aluminum. The presence of these twins is directly related to the nanocrystalline structure, because they are not observed in coarse-grained pure aluminum. We propose a dislocation-based model to explain the preference for deformation twins and stacking fa...

Nano-sized cellulose crystals were fabricated from microcrystalline cellulose (MCC) using combined sulfuric acid hydrolysis and high-pressure homogenization techniques. The crystals were then utilized to prepare polymethylmethacrylate (PMMA) nanocomposites by the solution casting method. The cellulose nanocrystals had diameters from about 8 to 10nm and lengths in the range of 60-120 nm. Wide-an...
