Eliminating the hazardous dyes from wastewater is essential for sustainable furtherance of eco-friendly-oriented industrial growth. The untreated effluents containing can damage ecosystem and cause serious health issues to humans, animals, aquatic species. In present work, multi-wall carbon nanotubes (MWCNTs) were functionalized using combination sulphuric acid nitric acid. These (F-MWCNTs) characterized Fourier transform infrared spectroscopy (FTIR) energy dispersive X-ray analysis (EDAX)...
In the present work, gold (Au), silver (Ag), and copper (Cu) based mono- bimetallic NPs are prepared using a cost-effective facile wet chemical route.

FESEM TEM micrographs used to analyze morphology of nanoparticles. images nanoparticles (BMPs) verified their nature. XRD studies confirmed formation fcc-structured NPs. Photoluminescence as-synthesized good...
A simple and robust platform, based on polymer-grafted nanoparticles to facilitate a controlled morphology of nano-fillers, provides route for strategically designing nanostructured EM wave absorbers with percolated MWCNT network as well NP arrangement.
Abstract Reduced graphene oxide-based nanocomposites are eminent materials having diverse applications including environmental remediation. The present work emphasizes the facile one-step co-reduction method for synthesizing silver nanoparticle (Ag NPs) decorated reduced oxide (RGO) catalytic reduction of 4-nitrophenol. FDTD simulation studies justify experimental results, and XRD confirmed formation Ag NPs with (AgRGO) composite. Raman analysis complements structure, crystallinity, defects...
Electric generation of spin current via Hall effect is great interest as it allows an efficient manipulation magnetization in spintronic devices. Theoretically, can be also created by a temperature gradient, which known Nernst effect. Here, we report effect-induced transverse magnetoresistance ferromagnet (FM)/non-magnetic heavy metal (HM) bilayers. We observe that the magnitude (i.e., planar signal) FM/HM bilayers significantly modified HM and its thickness. This strong dependence on...
Abstract In this article, we present a straightforward in-situ approach for producing Ag NPs incorporated in graphene oxide (GO) blended with glutaraldehyde (GA) cross-linked polyvinyl alcohol (PVA) matrix.

We performed FDTD modeling verify effect polarization periodicity on absorptivity...
In this study, we demonstrate an efficient optical-to-thermal energy-conversion (self-heating) ability of room temperature (RT)-grown gallium nitride (GaN) thin films on direct amorphous glass substrates. Radio frequency (rf) magnetron sputtering was employed to experimentally achieve the RT crystallinity these directly Finite-difference time-domain (FDTD) simulations are implemented elucidate their optothermal response. Our experimental approach precludes need for conventional prerequisites...
Fe 3 O 4 nanoparticles dispersed on single‐walled carbon nanotube (SWCNT) composites are synthesized through a simple in‐situ co‐arc discharge process followed by an annealing process. A well‐integrated /SWCNT composite exhibiting the strong microwave absorption (MA, −36.9 dB at 10.5 GHz) and wide effective bandwidth (5.5 is obtained controlling conditions. The high MA performance of this was ascribed to well integration magnetic (Fe ) SWCNT, creating synergetic effect. This work...
The photothermal energy conversion mechanism in pseudocapacitive nanoelectrodes endures temperature-enervated power dissipation due to self-heating, leading rapid heating and cooling cycles during the redox reactions triggered by plasmonic excitation.
