This study presents the application of biosynthesized silver nanoparticles (AgNPs) for modifying surface ultrafiltration membranes to confer antimicrobial properties. The AgNPs were synthesized using leaf extract medicinal plant Mimusops elengi L, and their characterization was carried out UV spectroscopy, FTIR, XRD, FESEM, HRTEM, AFM analyses. optimal conditions synthesis determined be 240 min reaction time, pH 9.5, 1:1 (v/v) ratio initial concentration precursor bio-extract, 323 K...
The present investigation was carried out in kharif season 2022-23 at Agronomy Research Farm of Chandra Bhanu Gupta Krishi Snatakottar Mahavidyalaya, Bakshi ka Talab, Lucknow (U.P). 8 treatments comprised T1- RDF(IF), T2- 100% RDF+25 kg ha-1 ZnSO4 (B), T3-100% RDF+2 foliar spray ZnSO4, T4- RDF+50 FeSO4 (B),T5-100% RDF+ZnSO4 25 (B) + @ 50 T6- 75% RDF (IF)+25% RDN (FYM), T7- 50% (IF)+50% (FYM),T8-100% through FYM were laid Randomized Block Design (RBD). soil silty-loam texture with slightly...
An experiment entitled Integrated Weed Management in transplanted rice (Oryza sativa L.)” was conducted at Shradhay Bhagwati Singh Agriculture Research Farm, Hajipur, Chandra Bhanu Gupta Post Graduate College, B.K.T., LUCKNOW (U.P.) during Kharif season of 2022-2023. The treatment comprised 9 weed management practices. Weedy check till maturity, free upto 60 DAT, Pretilachlor 50 % EC @ 1.25 kg a.i/ha (PE), Pendimethaline 30 @1.0 1.0 + 1 hand weeding 30DAT, (PE) Bispyribac Sodium 10 SC 25 g...
Abstract A comparative study of Eu 3+ photoluminescence in the Scheelite‐type oxides LiGd(WO 4 ) 2 and LiGd(MoO is made. From emission results, it observed that 5 D 0 → 7 F electric dipole transition at 615 nm predominant both cases. The critical concentration found to be x =0.3 LiGd 1‐ (WO as well (MoO . intensity higher tungstate host lattice vis a molybdate. In addition, 0.7 0.3 3.3 times compared Y O 3 :0.05Eu commercial red phosphor.
Abstract CaY 1‐x Eu x TiNbO 7 compositions with pyrochlore structure were synthesized by solid state reaction technique and photoluminescence was studied. Photoluminescence emission results reveal that the 5 D 0 → F 1 magnetic dipole transition has higher intensity indicating 3+ occupies a centrosymmetric site in host lattice. The critical concentration of found to be =0.5. 0.5 phase shows orange‐red when compared commercial red phosphor, Y 2 O 3 :Eu .
Abstract Na 0.5 Gd 0.5‐ x RE TiO 3 (RE=Eu and Dy) phases with orthorhombic perovskite structure were synthesized by high temperature solid state reaction the photoluminescence properties investigated. The phase purity was confirmed Rietveld refinement of powder XRD patterns in Pnma space group. band gap host found to be 3.41 eV from UV/Vis diffuse reflectance spectrum. In Eu 3+ doped phases, 5 D 0 → 7 F 2 electric dipole (ED) transition is predominant emission spectrum , under 397 nm...
The escalating energy demand coupled with limited conventional resources led to a widening gap between supply and demand, making it inevitable look for novel efficient technologies. Solid state lighting is one of the promising areas where significant amount consumed can be conserved without compromising on sophistications lighting. kindled interest researchers owing their impressive efficiency, longer life time, greater reliability, eco-friendly nature reasonable ease fabricating white light...
Li5La2.95Eu0.05M2O12 (M= Nb, Ta) compositions with garnet structure were prepared by conventional solid state reaction technique and photoluminescence was studied. The disclose that the 5D0→7F2 electric dipole transition at 611 nm is predominant in both cases; a clear evidence Eu3+ occupies non-centrosymmetric site these host lattices. These emission results are contrary to reported luminescence Y3Al5O12 (YAG). From studies, it can be concluded next nearest neighbors (NNN) cations influence phases.
