Magnetic chitosan-silk fibroin hydrogel/graphene oxide nanobiocomposite for biological and hyperthermia applications

A Review of the Recent Advances in Development of Noble Metal‐Free Materials as Electrocatalysts for Hydrogen and Oxygen Evolution Reactions

“…Graphene has enticed significant attentions for various applications in the fields of environment, medicine, electronics, optic, and energy. [130][131][132] Synthesis of graphene from bulk is commonly classified to the several methods [130] , among which chemical exfoliation is one of the most interesting methods due to the creation of many oxygen-related defects. Oxygenated graphene supplies both Lewis acidic and basic sites, which brings the unusual catalytic behavior of graphene.…”

“…The discovery of graphene as a layered 2D material with exceptionally large surface area has caused a great revolution in the field of carbon‐based nanomaterials. Graphene has enticed significant attentions for various applications in the fields of environment, medicine, electronics, optic, and energy [130–132] . Synthesis of graphene from bulk is commonly classified to the several methods [130] , among which chemical exfoliation is one of the most interesting methods due to the creation of many oxygen‐related defects.…”

Fabrication and characterization of a novel magnetic nanostructure based on pectin–cellulose hydrogel for in vitro hyperthermia during cancer therapy

“…1 Hydrogels based on synthetic and natural polymers are effective substrates that render a portentous architecture employed in different scientific facets, including environmental fields, 2 biosensors, 3 tissue engineering, 4,5 agriculture, 6 and biotechnology. 7 Compared to synthetic-based hydrogels, natural-based ones, such as agar, 8 pectin, 9 lignin, 10 cellulose, 11 chitosan, 12 and alginate, 13 are better candidates in green chemistry because of their biodegradable, biocompatible, and low-toxicity structure. 14…”

Preparation and characterization study of γ-Fe2O3/carbon composite nanofibers: electrospinning of composite fibers using PVP and iron nitrate as precursors

“…12 However, metal oxide/carbon nanocomposite materials improve the properties of both the metal oxide and the carbon fibers, making them ideal materials for a wide range of applications such as in optoelectronics, water decontamination, gas sensing, photonics, catalysis, heavy metals removal, photocatalysis, and energy storage. [13][14][15][16][17][18] Nanocomposites based on carbon exhibit different morphologies, such as carbon nanofibers or nanotubes decorated with metal oxides, metal oxide nanoparticles incorporated into carbon sheets between reduced graphene oxide layers, and porous carbon spheres that include metal oxide of various sizes. 14 Metal oxides such as magnetic iron oxide have attracted widespread attention because of their advantages of the easy availability of raw materials, non-toxicity, high chemical and physical stability, good magnetic properties, and low cost.…”
