Abstract Nanocrystalline cellulose (NCC) is an emerging renewable nanomaterial that holds promise in many different applications, such as personal care, chemicals, foods, pharmaceuticals, etc. By appropriate modification of NCC, various functional nanomaterials with outstanding properties, or significantly improved physical, chemical, biological, well electronic properties can be developed. The nanoparticles are stabilised aqueous suspension by negative charges on the surface, which produced...
A sulfur electrode exhibiting strong polysulfide chemisorption using a porous N, S dual-doped carbon is reported. The synergistic functionalization from the N and heteroatoms dramatically modifies electron density distribution leads to much stronger binding. X-ray photoelectron spectroscopy studies combined with ab initio calculations reveal Li(+) -N Sn (2-) -S interactions. electrodes exhibit an ultralow capacity fading of 0.052% per cycle over 1100 cycles.
Pickering emulsions with stimuli-responsive properties have, in recent years, received a considerable amount of attention. This paper provides concise and comprehensive review emulsion systems that possess the ability to respond an array external triggers, including pH, temperature, CO<sub>2</sub>concentration, light intensity, ionic strength, magnetic field intensity.
A weak polyelectrolyte, poly[2-(dimethylamino)ethyl methacrylate] (PDMAEMA), was grafted onto the surface of cellulose nanocrystals via free radical polymerization. The resultant suspension PDMAEMA-grafted-cellulose (PDMAEMA-g-CNC) possessed pH-responsive properties. grafting confirmed by FTIR, potentiometric titration, elementary analysis, and thermogravimetric analysis (TGA); interfacial properties modified particles were characterized tensiometer. Compared to pristine nanocrystals, CNC...

PEI acts not only as a cross-linker but also chelating agent for RE ions.
The most abundant natural biopolymer on earth, cellulose fiber, may offer a highly efficient, low-cost, and chemical-free option for wastewater treatment. Cellulose is widely distributed in plants several marine animals. It carbohydrate polymer consisting of β-1,4-linked anhydro-D-glucose units with three hydroxyl groups per anhydroglucose unit (AGU). Cellulose-based materials have been used food, industrial, pharmaceutical, paper, textile production, treatment applications due to their low...
In view of a great demand for paper-based technologies, nonwettable fibrous substrates with excellent durability have drawn much attention in recent years. this context, the use cellulose nanofibers (CNFs), smallest unit cellulosic (5–20 nm wide and 500 to several microns length), design waterproof paper can be an economical smart approach. study, eco-friendly facile methodology develop multifunctional via fabrication fluoroalkyl functionalized CNFs aqueous medium is presented. This strategy...
Cellulose nanocrystal (CNC), a class of sustainable nanomaterial derived from forest and agro-biomass can serve as nature's storage for carbon dioxide.
Paper-based materials have been widely used in packaging replacing nonbiodegradable fossil-based polymers due to the increasing concerns on environmental pollution. However, paper is hygroscopic and its mechanical strength dramatically reduced presence of moisture. The current hydrophobic modification via polymer coating hinders recycling paper. A sustainable approach was proposed prepare superhydrophobic cellulose nanocrystals (CNCs) by anchoring octadecylamine (ODA) surface CNCs...
Abstract The effects of electromagnetic (EM) radiation have received increased attention, closely associated with the widespread use electronics and wireless communication. A significant development in area is recent adoption metal‐organic frameworks (MOFs) to effectively enable interference (EMI) shielding. MOF tunable molecular scaffold architecture offers numerous pathways generate customizable magnetic electrical properties, which are prerequisite materials characteristics for efficient...
