The one-step synthesis of polymer-based magnetic γ-Fe2O3/carboxymethyl cellulose nanocomposites

Magneto-sensitive hybrid nanocomposites of water-soluble sodium alginate cross-linked with calcium ions and maghemite

“…In the alginate spectrum ( Figure 6 curve 1) the bands at ν = 1600 and 1420 cm -1 relate to the antisymmetric and symmetric stretching vibrations of carboxyl groups, respectively ( Figure 6 curve 1). These groups are mainly in a deprotonated (charged) form [47,48]. The band at ν = 1730 cm -1 is associated with stretching vibrations of C=O fragments in carboxyl groups; this band is due to intraand intermolecular hydrogen bond formation.…”

Spectroscopic investigation of green synthesized ZnS nanoparticles encapsulated by sodium carboxy methyl cellulose

“…In view of its high transparency, good film-forming property, large mechanical strength, non-toxicity and biodegradability, it is found suitable for applications such as medicine, flocculating agent, chelating agent, emulsifier, thickening agent, water-retaining agent, sizing agent, and film-forming material [10][11][12]. Recent reports on NaCMC reveal that it works as a stabilizer in the preparation of certain semiconducting nanosized materials like PbO nanoparticles [13], ZnO [14], CdS [15], ZnS [16] and some magnetic nanoparticles such as Fe 3 O 4 [17,18]. Increase in light emission intensity has been reported in ref [16].…”

Green Procedure to Manufacture Nanoparticle-Decorated Paper Substrates

“…One way to create the new materials is to include inorganic matter having particular properties. In this context, the incorporation of functional inorganic nanoparticles (NPs) (e.g., antimicrobial, conductive, photoactive, catalytic, magnetic, Raman active) into different types of cellulosic substrates has been described for many cellulosic materials [1,2,3,4,5,6,7,8,9]. In principle, there are different ways of implementing nanoparticles into these materials.…”
