We fabricated localized surface plasmon resonance enhanced UV photodetectors on MOCVD grown semi-insulating GaN. Plasmonic resonance in the UV region was attained using 36 nm diameter Al nanoparticles. Extinction spectra of the nanoparticles were measured through spectral transmission measurements. A resonant extinction peak around 300 nm was obtained with Al nanoparticles. These particles gave...

TiO2 nanotube arrays are well-known efficient UV-driven photocatalysts. The incorporation of graphene quantum dots could extend the photo-response of the nanotubes to the visible-light range. Graphene quantum dot-sensitized TiO2 nanotube arrays were synthesized by covalently coupling these two materials. The product was characterized by Fourier-transform infrared spectrometry (FTIR), scanning e...

Pure bisthiourea cadmium bromide (BTCB) and 1 mole % L-alanine mixed bisthiourea cadmium bromide (LABTCB) single crystals have been grown by slow evaporation method. The grown crystals have been characterized by single crystal XRD analysis, powder XRD analysis, FTIR analysis, UV-Vis-NIR analysis and SHG studies. XRD analysis confirms the crystalline nature of the materials. The addition of L-al...

We report on an anti-resonant hollow-core fiber (AR-HCF) designed for stable transmission of laser light in a broad wavelength range 250 nm to 450 nm. tested wavelengths 300 and 320 The characterized shows low power attenuation 0.13 dB/m excellent single-mode profile. maintains after exposure tens hours with up 60 mW CW-laser no indication solarization effects. further its performance under ben...

Transmission electron microscopy has been employed to study the structure of polycrystalline CsI thin "lms and its transformation under exposure to humid air and UV irradiation. The catastrophic degradation of CsI thin "lm photocathode performance is shown to be associated with the "lm dissolving followed by its re-crystallization. This results in the formation of large lumps of CsI crystal on ...

The development of green and safe processes for the synthesis of nanomaterials is one of the main aspects of nanotechnology. In this study, a biological, inexpensive and rapid process for the fabrication of palladium nanoparticles using the aqueous broth of Pistacia Atlantica fruit as a novel biomass product is reported without using extra surfactant, capping agent, and template. The synthesize...

In this work, we report synthesis and characterization of Bi2O3 nanoparticles loaded on mesoporous MCM-41 nanoparticles by a simple solid-state dispersion (SSD) method. Monoclinic bismuth oxide nanoparticles were prepared by polyacrylamide gel method and used as loading materials on the prepared mesoporous MCM-41 as a supporting material. Fourier transform infrared spectroscopy (FT-IR), X-ray p...

Background and Aims: Despite the screening of blood donors, blood transfusion represents an ideal port of entry for blood-borne infection. Blood-borne pathogen transmission has been a concern since the earliest days of transfusion. The blood product of platelet (PLT) concentrates is still faced with the risk of bacterial and viral contaminations. Pathogen inactivation technologies offer a proac...

Molecular sieves MCM-41 were synthesized from rice husk ash (RHA) as alternative sources of silica. The material was synthesized by a room temperature method from a gel with the molar composition SiO2: 1.6EA: 0.215HDTMABr: 325H2O with pH correction. The cetyltrimethylammonium bromide (CTMABr) was used as a structure template. Nanocomposite containing 5.0 and 10.0 wt.% of Cu was synthesized unde...
