How do trees support their upright massive bodies? The support comes from the incredibly strong and stiff, and highly crystalline nanoscale fibrils of extended cellulose chains, called cellulose nanofibers. Cellulose nanofibers and their crystalline parts-cellulose nanocrystals, collectively nanocelluloses, are therefore the recent hot materials to incorporate in man-made sustainable, environmentally sound, and mechanically strong materials. Nanocelluloses are generally obtained through a top-do...

Abstract Pollution is regarded as one of the global biggest challenges towards sustainability of mankind. Studies have discovered that high percentage of these pollutants are from industrial by-product source, mostly from combustion of fuels during manufacturing and other applications. The introduction and acceptance of smother burning fuels together with less harmful chemical (lubricants) began to gain ground, owing to the worldwide environmental concern. This drastically pushes into utilizatio...

The main goal of the present work was to develop a value-added product of biodegradable material for sustainable packaging. The use of agriculture waste-derived carboxymethyl cellulose (CMC) mainly is to reduce the cost involved in the development of the film, at present commercially available CMS is costly. The main focus of the research is to translate the agricultural waste-derived CMC to useful biodegradable polymer suitable for packaging material. During this process CMC was extracted from ...

Abstract Supramolecular self-assembly, based on non-covalent interactions, has been used as an effective method to obtain various functional materials. In this work, a water soluble atomically precise Ag NCs(NH4)9[Ag9(C7H4SO2)9] (Ag9-NCs, [Ag9(mba)9], H2mba = 4-mercaptobenzoic acid) and cellulose nanocrystals (CNCs) were used to prepare supramolecular hydrogels by self-assembly, and these hydrogels have been characterized by using various techniques. The results revealed that the strong hydrogen...

Abstract A semi-interpenetrating polymer network (semi-IPN) superabsorbent hydrogel composite based on starch (St)-graft-poly(acrylic acid (AA)-co-acrylamide (AM))/polyvinyl alcohol (PVA) and cellulose nanocrystals (CNC) was synthesized using free radical aqueous polymerization method. Cellulose nanocrystals were extracted from potato peel waste using alkali treatment followed by acid hydrolysis. FTIR analysis affirmed the grafting reaction of acrylate-based monomers onto starch backbone as well...

Abstract Waste water remediation of toxic metals and dye could be complex to achieve owing to several factors. Various techniques have been developed for the removal of these pollutants. However, the success of these water treatment techniques mainly depends on the choice of appropriate media. Most of the commercial and chemically synthesized materials for water treatment create additional hazards due to the leaching of toxic chemicals into the process water. Consequently, studies on the develop...

Abstract Cellulose nanocrystal (CNC) based nanohybrids are emerging as multifunctional materials and alternative to traditional petroleum-based plastics. The growth in academic and industrial interest in this field is highlighted by the increasing number of works published in the last decade. While several reviews have been written to focus on the synthesis of these materials, little has been done to catalogue the properties and potential applications of CNC based multifunctional nanohybrids. In...

Abstract Dielectric barrier discharge plasma was used to functionalize cellulose nanocrystal (CNC) films. The plasma was induced in different gas mixtures: argon/methane (Ar/CH4), argon/ammonia (Ar/NH3) and argon/silane (Ar/SiH4). The functionalized samples were characterized by X-ray diffraction (XRD), water contact angle (WCA) measurements, X-ray photoelectron spectroscopy (XPS) and atomic force microscopy (AFM). The wettability of the cellulose nanocrystals depends on the gas mixture while XR...

Abstract This article reports on fabrication of activated TiO2 and gold decorated TiO2 prepared by irradiation with millisecond laser and on their gas sensing properties. Commercially available anatase TiO2 was used as starting material whose nanoparticles were modified and decorated upon irradiating its water suspension by pulsed laser. Formation of Au nanoparticles was achieved by laser-induced reduction of Au(III) ions, followed by their deposition onto TiO2 nanoparticle surface. In order to ...

Abstract Cellulose nanocrystals (CNCs) have received a significant amount of attention from the researchers. It is used as a nanomaterial for various applications due to its excellent physiochemical properties for the last few decades. Self-assembly is a phenomenon where autonomous reorganization of randomly oriented species occurs elegantly. Self-assembly is responsible for the formation of the hierarchical cholesteric structure of CNCs. This process is highly influenced by several factors, suc...
