ABSTRACT Adsorption is the most efficient technique for the removal of metal ions and organic dyes from water. This stimulates demand for the preparation of eco-friendly adsorbents. In this study, magnetic hydrogels based on a crosslinked carboxymethyl cellulose grafted acrylamide (CMC-g-AM) embedded with porous carbon (PC) and citric acid-modified magnetite were prepared. PC was synthesized via single-step oxidation of bagasse under muffled atmosphere condition. The magnetite (Fe3O4) nanopartic...

Cellulose has attracted much interest, particularly in medical applications such as advanced biosensing devices. Cellulose could provide biosensors with enhanced biocompatibility, biodegradability and non-toxicity, which could be useful for biosensors. Thus, they play a significant role in environmental monitoring, medical diagnostic tools, forensic science, and foodstuff processing safety applications. This review summarizes the recent developments in cellulose-based biosensors targeting the mo...

A facile approach for possible industrial production of long-persistent phosphorescence, continuing to emitting light for a long time period, smart cobbles were developed toward photoluminescent hard surfaces. The inorganic strontium aluminium oxide pigment doped with rare earth elements was added to a synthetic organic epoxy in the presence of polyamine as a hardener to make a phosphor-loaded viscous fluid that can then be hardened in a few minutes. The transparency of the solid cobbles can be ...

Abstract Cyanoethyl cellulose (CEC)/ magnetite (Fe3O4) flexible composite film with enhanced dielectric and magnetic properties was successfully prepared. CEC has been synthesized from micro crystalline cellulose (MCC). The effects of magnetite mass fraction on the morphology, microstructure, thermal stability, and antimicrobial activity of the as-prepared composite films were investigated. The Vibrating sample magnetometer (VSM) and broadband dielectric spectrometer was also employed to study t...

Nanocomposites of polymethyl methacrylate (PMMA)/cellulose nanocrystals (CNC) have been developed through physical mixing of different ratios of CNC with dissolved PMMA. Solvent exchange method has been carried out in order to increase the dispersion of CNC in the polymer matrix. The obtained composite films showed high transparency. Moreover, its barrier properties against water vapor were significantly increased. The nanocomposite films were further coated with a layer of polyaniline (PANI) wh...

Abstract We developed novel electrically conductive nanocomposites based on cellulose nanowhiskers (CNW) via in situ emulsion polymerization reaction of pyrrole and in presence of silver nitrate (AgNO3) as an oxidative agent and surfactant. CNW were employed as carriers comprising high surface area-to-volume ratio and high porosity. Nickel(III) oxide (Ni2O3) nanoparticles were loaded onto the prepared composites using the sol-gel technique to provide nanocomposites of potentially excellent prope...

The objective of this work is to re-use of agriculture waste via an environmentally friendly procedure to introduce multifunctional cellulose-based blend films using sesame seed meal extracted from agriculture wastes. The current strategy demonstrated the identification and evaluation of the bioactive compounds of sesame seed meal extracted from agricultural wastes via an ultrasonic procedure. Then, the sesame seed meal extract was loaded onto modified carboxymethyl cellulose within a matrix of ...
