High-energy-density storage devices play a major role in modern electronics from traditional lithium-ion batteries to supercapacitors for variety of applications rechargeable advanced military equipment. Despite the mass adoption polymer capacitors, their application is limited by low energy densities and low-temperature tolerance. Polymer nanocomposites based on 2D nanomaterials have superior ...

Abstract To curtail flammability risks and improve material properties, flame retardants (FRs) fillers are mixed into rubbers. High loadings of aluminum trihydroxide (ATH) carbon black (CB) the most used FRs reinforcing additive, respectively, in reduce loading without losing mechanical partial substitution ATH as well CB by low amounts multilayer graphene (MLG) nanoparticles is investigated. T...

This study evaluated the effectiveness of different sealants applied to a nanofiller composite resin. Forty specimens of Filtek Z-350 were obtained after inserting the material in a 6x3 mm stainless steel mold followed by light activation for 20 s. The groups were divided (n=10) according to the surface treatment applied: Control group (no surface treatment), Fortify, Fortify Plus and Biscover ...

OBJECTIVE To compare wear performance and resistance to crack propagation (K1C) of commercial restorative materials and their flowable variations. A potential correlation between three-body wear and fracture toughness, modulus of elasticity, fracture work, Vickers hardness, and filler content was investigated. METHOD AND MATERIALS Seven restoratives (five composites, one ormocer, and one comp...
