Synthesized novel chromogenic reagent and sensor: Detection and identification of dichlorvos.

We developed a novel chromogenic reagent and sensor by selective approach, for the detection and identification of dichlorvos, which we tested with the thin layer chromatography method. For the first time, we reported in situ-generated glyoxal as a hydrolysis product, which then interacts with isoniazid to produce a yellow-colored cyclic compound. We used well-known spectroscopic techniques to confirm the chemical identity of the final product.

In silico prediction, characterization and molecular docking studies on Glutathione-S-transferase as a molecular sieve for toxic agrochemicals explored in survey of North Indian farmers.

All across the globe, India is considered as an agricultural nation because its agro products drive the economy. An increase in population growth and a hike in food demands lead to the use of hazardous chemicals in farm fields. An in-depth field survey in Northern India was conducted to understand the types of agrochemicals that were used, farmers' knowledge about their safe handling, and their practices on its usage.

Improvement of quantum efficiency through Gd to Eu energy transfer in YF phosphor.

This paper reports the energy transfer from Gd to Eu in YF and the consequent downconversion luminescence for the YF :Gd , Eu fluoride phosphor. The phosphor was synthesized using a soft chemical route, followed by a reactive atmosphere process. Because of the wide band gap in YF and the correct energy site for S - G transitions of Gd ions, fluoride YF doped with Gd -Eu were studied in their vacuum-ultraviolet (VUV) spectral regions.

Gamma radiation shielding characteristics of various spinel ferrite nanocrystals: a combined experimental and theoretical investigation.

This work presents the facile synthesis of Ni, Mn, Zn, Cu and Co spinel ferrite nanocrystals sol-gel auto-ignition and the investigation of their structural and gamma ray shielding characteristics. Experimentally, gamma ray shielding parameters are determined with different gamma ray sources and NaI(Tl) scintillation detector and theoretically Monte-Carlo simulation (Geant4) as well as NIST-XCOM database. X-ray diffractograms elucidate the cubic spinel structure without any contaminating phases for all synthesized nano-ferrites.

Induction Heating Analysis of Surface-Functionalized Nanoscale CoFeO for Magnetic Fluid Hyperthermia toward Noninvasive Cancer Treatment.

Oleic acid-coated cobalt ferrite nanoparticles were synthesized using the chemical co-precipitation route and characterized by standard techniques for structure, morphology, and magnetic properties analysis. The Rietveld refined X-ray diffraction (XRD) pattern of CoFeO nanoparticles indicated the formation of a cubic-spinel single-phase structure with the F3̅ space group. The average crystallite size (∼12 nm) confirmed the nanocrystalline appearance of the prepared CoFeO nanoparticles.

Influence of trivalent Cr ion substitution on the physicochemical, optical, electrical, and dielectric properties of sprayed NiFeO spinel-magnetic thin films.

In this study, we mainly investigated the effects of trivalent Cr ion substitution on the properties of nickel ferrite (NCF) spinel-thin films. The as-prepared spinel thin films were characterized by thermogravimetry-differential thermal analysis (TGA-DTA) to comprehensively examine their phase transition. X-ray diffraction (XRD) analysis revealed that the prepared films have a single-phase face-centered cubic crystal structure.

Near-infrared emitting Ca (PO ) Cl:Eu ,Nd phosphor for modification of the solar spectrum.

Intense near-infrared (NIR) emitting phosphors Ca (PO ) Cl:Eu ,Nd were synthesized using a conventional solid-state reaction method and characterized using X-ray diffraction, reflectance, photoluminescence (PL) emission and PL excitation (PLE) spectroscopy, and PL lifetime measurements. The emission could be excited by broad band radiation in the nUV region as a consequence of Eu →Nd energy transfer. The efficiency of Eu →Nd energy transfer was as high as 80.

Synthesis and Characterization of Cr(III), Mn(III), Fe(III), VO(IV), Zr(IV) and UO2(VI) Complexes of Schiff Base Derived from Isonicotinoyl Hydrazone.

2-hydroxy-5-chloro-3-nitroacetophenone isonicotinoyl hydrazone as a Schiff base ligand and its complexes with Cr(III), Mn(III), Fe(III), VO(IV), Zr(IV) and UO2(VI) metal ions have been synthesized.

Susceptibility pattern of various azoles against Candida species causing vulvovaginal candidiasis.

Objectives: Vulvovaginal candidiasis (VVC) is a common gynecological finding among the women worldwide. Candida species are often less susceptible to antifungal agents. Owing to this fact, in this study, we aimed at assessing the prevalence rate and antimicrobial susceptibility pattern of various azoles against Candida species causing VVC in symptomatic women.
