Radiotherapy which consists of external beam radiotherapy (EBRT) and internal radioisotope therapy (RIT), has a wide usage for treating cancer as clinical trials.This study provides some conditions to prove that tungsten oxide nanoparticles (WO3) is a radiosensitizer.The peripheral blood mononuclear cells (PBMCs) were used to calculate inhibitory concentration (IC).The AGS cell line exposed the...

in this work, hierarchical wo3 core-shell microspheres were synthesized via a facile template-free precipitation method. gas sensing properties of the synthesized powder to acetone and some other volatile organic compounds were comparatively investigated with commercial wo3 nanoparticles. the synthesized and commercial powders were characterized by x-ray diffraction, scanning electron microscop...

The radiation shielding abilities of waste marbles with different concentrations WO3 (tungsten oxide) nanoparticles were investigated. Four prepared 0, 0.05, 0.1, and 0.2 nanoparticles. study aims to investigate the effect concentration, density, particle size marble samples. linear attenuation coefficient (LAC) S1 sample, sample no WO3, was determined theoretically experimentally, results demo...

Exceptional properties of graphene have triggered intensive research on other 2D materials. Surface plasmon is another subject being actively explored for many applications. Herein we report a new class of core-shell nanostructure in which the shell is made of a 2D material for effective plasmonic propagation. We have designed a much enhanced chemical sensor made of plasmonic Ag(x)@(2D-WO3) tha...

A series of supported WO3 catalysts were synthesized by incipient wetness impregnation of ammonium metatungstate aqueous solutions onto Al2O3, TiO2, Nb2O5, and ZrO2 supports as a function of tungsten oxide loading. The resulting solid acid catalysts were physically characterized with in situ Raman and UV–vis spectroscopy and chemically probed by methanol dehydration to dimethyl ether (CH3OH-TPS...

The use of TiO2 nanoparticles in organic-based photocatalytic coatings imposes several challenges: poor activity under visible light, binder photo-degradation, need for UV activation and toxicity concerns. Here we present a scalable two-step synthesis route to prepare TiO2-based hollow microspheres (HoS) as alternative photocatalyst commercial nanoparticles. or WO3-doped (3 mol% WO3) are synthe...

Nowadays, hydrogen has attracted significant attention as a next generation clean energy source. Hydrogen is highly flammable, so detection of hydrogen gas is required. Gold nanoparticle based localized surface plasmon resonance (LSPR) is an advanced and powerful sensing technique, which is well known for its high sensitivity to surrounding refractive index change in the local environment. We p...

In this study, Pt-M/WO3 (M = Cu, Co, and Ni) thin films are effectively synthesized by preparing homogeneous precursor sols, spin-coating, toluene-etching, calcination. Furthermore, the microstructural, chemical, electrochemical properties of WO3, Pt-Cu/WO3, Pt-Co/WO3, Pt-Ni/WO3 also systematically compared. The results demonstrate that when compared to WO3 film, photocatalytic capability for m...

In the present study, we fabricated tungsten trioxide nanoparticles (WO3 NPs) from a complex [W(C13H10NO)3] of ligand N-salicylideneaniline with tungstic acid as precursor. Nanoparticles were synthesized using direct thermal decomposition method. These evaluated for cytotoxicity influence on human breast cancer MCF7 cell line (adenocarcinoma). The observed results suggested that WO3 can destroy...
