We employed density functional theory to inspect the impact of Ir-decoration on sensing performance a GaN nanotube (GaNNT) in detection mesalamine (MA). The interaction pristine GaNNT with MA was found be weak, and response approximately 4.3. Decorating an Ir atom into surface increased adsorption energy (Ead) from −6.7 −23.8 kcal/mol. significantly 89.4 after decorating atom. A short recovery time 22.0 s for desorption Ir-decorated at 298 K. water solvent reduced Ead −19.8 Thus, we...
In the last few decays, fiber-optic was employed in field of sensing because its benefits contrast to other types sensors such as small size, easy fabricate, high response, and flexibility. this study, unclad single mode sensor is proposed operate at 650 nm wavelength. COMSOL Multiphysics 5.1 finite element method (FEM) used design tested it theoretically. The middle portion fiber cladding removed replaced by gold nanoparticles (Au NPs) 50 thickness. Analytic layer 3 μm thickness immersed...
This study proposed an unclad optical fiber biosensor based on the localized surface plasmon resonance phenomenon and operating at 650 nm using COMSOL Multiphysics 5.1 finite element method (FEM). Gold nanoparticles (50 thickness) were coated middle portion of fiber. Air, water, blood plasma, liver tissue, colon pentanol (C5H11OH) used as analytical layers with 3 µm. The sensor serves a theoretical foundation for experimental research. plasma had highest sensitivity 10,638.297 nm/RIU...
Gallium nitride (GaN)/porous silicon (PSi) film was prepared using a pulsed laser deposition method and 1064 nm Nd: YAG for optoelectronic applications series of Psi substrates were fabricated photoelectrochemical etching assisted by at different times 2.5–15 min 2.5 intervals. X-ray diffraction, room-temperature photoluminescence, atomic force microscopy field emission scanning electron images, electrical characteristics in the GaN on investigated. The optimum substrate obtained under...
Herein we introduce a novel and reusable nanomagnetic copper catalyst (Fe3O4@SiO2-Imine/Thio-Zn(OAc)2) constructed by immobilizing Zn (II) complex on the surface of magnetic nanoparticles functionalized with Imine/Thio group. The structure as-constructed Fe3O4@SiO2-Imine/Thio-Zn(OAc)2 nanomaterial was well analyzed number spectroscopic techniques including: FT-IR, SEM, TEM, EDX, XRD, VSM, AAS ICP-OES. Experimental studies have revealed that is an ecofriendly efficient nanocatalyst for...
