The initial lithium loss during the formation stage is a critical issue that significantly reduces the specific capacity and energy density of current rechargeable lithium-ion batteries (LIBs). An effective strategy to solve this problem is using electrode prelithiation additives that can work as a secondary lithium source and compensate the initial lithium loss. Herein we show that nanocomposi...

Multiwall carbon nanotubes (MWCNTs) and carbon nanofibers (CNFs) with contents ranging from 1 to 10 phr (part per hundred parts of rubber) were selected and then characterized to reinforce acrylonitrile butadiene rubber (NBR) based composites. Fabrication of nanocomposites were done by a novel procedure and structural analysis along with variety of mechanical and chemical tests, according to th...

How to accurately control the microstructure of bioactive inorganic/organic nanocomposites still remains a significant challenge, which is of great importance in influencing their mechanical strength and biological properties. In this study, using a combined method of electrospinning and hot press processing, calcium silicate hydrate (CSH) nanowire/poly(L-lactide) (PLLA) nanocomposites with con...

The organoclay/poly(methyl methacrylate) (PMMA) nanocomposites were prepared by in situ photopolymerization method using two solvents, ethanol and acetonitrile. The influences of organoclay loading, solvent nature and length of attached surfactant (C8 or C16) on thermal and mechanical properties were studied by thermogravimetric analysis and dynamic mechanical analysis. Alkylammonium surfactant...

The design of cheap and safe antibacterial materials for widespread use has been a challenge in materials science. The use of copper nanostructures combined with abundant biopolymers such as cellulose offers a potential approach to achieve such materials though this has been less investigated as compared to other composites. Here, nanocomposites comprising copper nanofillers in cellulose matric...

The core-shell structural Fe3O4/ZnS nanocomposites with controllable shell thickness were well-fabricated via seed-mediate growth method. Structural and morphological characterizations reveal the direct deposition of crystalline II-VI compound semiconductor ZnS shell layer on Fe3O4 particles. Spin dependent electrical transport is studied on Fe3O4/ZnS nanocomposites with different shell thickne...

New water-soluble nontoxic nanocomposites of nanosized silver particles in a polymer matrix were synthesized by a green chemistry method. Nontoxic poly(1-vinyl-1,2,4-triazole) was used as a stabilizing precursor agent in aqueous medium. Glucose and dimethyl sulfoxide were used as the silver ion-reducing agents to yield silver nanoparticles 2-26 nm and 2-8 nm in size, respectively. The nanocompo...

PPY, PANI and PPY-PANI-ZnO ternary nanocomposites were synthesized in the laboratory via chemical oxidative polymerization method. The formation of corresponding change nanostructure with incorporation ZnO was examined by X-ray diffraction technique (XRD). Nano-flakes like structure formed PPY-PANI polymeric matrix embodiment nanoparticles, as surface topology images. Optical transmittance spec...

A method for producing nanocomposites of transition metal oxides A(3)O(4) (where A represents Mn, Fe or Co) and graphene nanosheets (GNS) is presented. The reduction of graphene oxide (GO) and the formation of A(3)O(4) nanoparticles (NPs) were carried out simultaneously during the reaction. The electrochemical properties of A(3)O(4)-GNS nanocomposites as electrode materials for supercapacitors ...

Graphene has attracted enormous attention owing to its extraordinary properties, while graphene-based nanocomposites hold promise for many applications.
