CoNi alloy nanoparticles anchored on a spherical carbon monolith (CoNi-C) were prepared by a solvothermal route and subsequent heat treatment without any templates. Their permittivity and permeability behaviors were studied in the frequency range of 2-18 GHz. The CoNi-C composites showed the best microwave absorbing performances compared to those of Co-C and Ni-C. The maximum reflection loss of...

Novel soft nanocomposite materials with unique organic/inorganic network structures have been developed by extending the strategy of "organic/inorganic nanocomposites" to the field of soft materials. The structures described here were synthesized by in-situ free-radical polymerization of various monomers in the presence of exfoliated clay (hectorite) in aqueous media. The nanocomposite hydrogel...

We characterize absorption in finite idempotent algebras by means of Jónsson absorption and cube term blockers. As an application we show that it is decidable whether a given subset is an absorbing subuniverse of an algebra given by the tables of its basic operations.

Optical generation of ultrasound using nanosecond duration laser pulses has generated great interest both in industrial and biomedical applications. The availability portable devices semiconductor technology optical fibres, as well numerous source material types based on nanocomposites, proliferated the applications ultrasound. nanocomposites can be deposited tip fibres planar hard soft backing...

Abstract The thermal properties of polymeric nanocomposites can be examined using TGA and DSC techniques, while dielectric through simulated scattering (S11, S12, S21, S22) parameters. Polyaniline (PAni) nanopowder was synthesized chemical oxidative polymerization techniques. Consequently, the crystallite size morphology powder were XRD, TEM, FESEM Further, a series developed via wet mixing com...

In this research work cobalt-ferrite (CoFe2O4) nanoparticles were synthesized by a simple, general sol-gel auto-combustion method. For this study, electromagnetic (EM) wave absorbing coatings with different weight fractions of nano-carbon and CoFe2O4 (which, arises from both dielectric and magnetic contributions) and polymeric epoxy resin were prepared and their characteristics were fully inves...

Photomechanical nanocomposites embedded with light-absorbing nanoparticles show promising applications in photoresponsive actuations. Near infrared (nIR)-responsive nanocomposites based photomechanical soft actuators can offer lightweight functional and underexploited entry into soft robotics, active optics, drug delivery, etc. A novel graphene-based photomechanical soft actuators, constituted ...
