Radar absorbing structural (RAS) composites are laminate with a low reflection coefficient for the electromagnetic illumination in microwave frequency range, and thus it can be used civil stealth applications. In this study, series of Exfoliated Graphite (EG) combination U-type barium hexaferrite based epoxy was fabricated varying weight percentages (0.25, 0.50, 0.75 1.00 wt%) EG fixed wt.% (60 through wet mixing compression moulding technique. Here, Raman spectra shows to defect-free...
In the present work, synthesized U-type barium hexagonal (Ba4Co1.5Zn0.5Fe36O60 or BaU) ferrite powder is further transformed into BaU/glass fiber-epoxy structural composites by hand lay-up process and compression moulding techniques using different volume percentages (11.4, 17, 26.4) within reinforced polymer matrix. Phase formation, surface morphology, magnetic properties XRD, FESEM, VSM techniques, respectively. Subsequently, electromagnetic absorbing of designed structures were measured...
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 compressor molding techniques for various volume percentages (54.0, 57.5, 60.1, 61.7 vol%) within...
CONTEXTEarly postoperative pain is common and predominant complaint which results in prolonged hospital stay. AIMSThe present study explores effectiveness of intraperitoneal instillation tramadol on relief emergence adverse effects following laparoscopic appendectomy. SETTINGS AND DESIGNThe one year double blinded randomized controlled trial was done the Department General Surgery, KLES Dr.
Micron size U-type barium hexaferrite powder have been synthesized by solid state reaction process. Powder X-ray diffractometer technique has used to confirm the phase of hexagonal through calculate lattice parameters. Field emission scanning electron microscope was morphology and prepared composites. Complex permittivity, complex permeability absorbing properties studied for all polymeric composites using Agilent vector network analyzer in frequency range 2-18 GHz. The minimum RL observed...
In this study, carbon black (CB) powder-loaded polyurethane (PU) composites (CB–PU composites) were prepared by melt mixing method with different volume percentages (45, 50, 55, 58 and 61 vol.%) of CB in the PU matrix. The CB–PU had been further studied for surface morphology using field-emission scanning electron microscopy (FESEM) technique. Dielectric properties terms real permittivity ([Formula: see text] imaginary fabricated computed an Agilent E8364B vector network analyzer frequency...
<title>Abstract</title> In this study, we investigate the microwave absorbing properties of epoxy based nanocomposites incorporated with polyaniline-manganese zinc ferrite (PAni-MZF) as hybrid active fillers. Carbonaceous materials due to their high conductivity and weight ratio have emerged a potential class electromagnetic interference (EMI) shielding while ferrimagnetic unique like; magneto crystalline anisotropic magnetic permeability. Consequently, constructed capable efficient...
