Elemental sulfur (S0), man's oldest eco‐friendly fungicide for curing fungal infections in plants and animals, is registered India as a non‐systemic contact fungicide. However due to its high volume requirement, Indian agrochemical industry farmers could not effectively use this product till date. We hypothesize that intelligent nanoscience applications might increase the visibility of nanosulfur agriculture potent eco‐safe Sulfur nanoparticles (NPs) were synthesized bottom‐up via liquid...
The study was aimed to develop a nano form of an existing fungicide for improving plant protection and reducing crop losses caused by fungal pathogens. protocol the preparation estimation nanohexaconazole developed. Technically pure hexaconazole converted into its nanoform using polyethyleneglycol-400 (PEG) as surface stabilizing agent. Nanohexaconazole characterized Scanning Electron Microscopy (SEM) Dynamic Light Scattering (DLS) studies. average particle size about 100 nm. An analytical...
Gold (Au) and silver (Ag) nanoparticles (NPs) are useful nanomaterials. For these NPs various synthesis methods including chemical, physical biological have been used. Biological some advantages for the of Au Ag NPs, such as use non-toxic chemicals, lower energy consumption, improved cost effectiveness stable NP production. A large number using culturable micro-organism, bacteria, fungi algae well plants explored methodology Since nanotechnology-based applications require specified shape,...
In order to identify the most suitable method for estimation of nanosulfur studying its residue dynamics, present work was taken up. HPLC and GC methods were explored analysis. A comparative study existing analytical quality control undertaken. UV spectrophotometry superior with lower LOD when compared GC-MS, which not satisfactory due breakage catenated S20 into S6 S8 . The has been validated by analyzing various formulations known concentrations. recovery ranged from 80.71 109.51% 82.31...
Nanohexaconazole is a highly efficient fungicide against Rhizoctonia solani. Nanoparticles are alleged to adversely affect the non-target organisms. In order evaluate such concern, present study was carried out investigate effect of nanohexaconazole and its commercial formulation on sensitive nitrogen fixing blue green algae (BGA) bacteria. Various activities bacteria namely growth, N-fixation, N-assimilation, Indole acetic acid (IAA) production phosphate solubilization were differently...
The present study shows the synthesis of magnetite nanoparticles by co-precipitation method in three steps. steps involve precipitation Fe3O4 followed layer functionalization with silica and tetraethoxy(octadyl)silane (C18). prepared were investigated SEM, TEM, XRD, FTIR VSM. It was suggested that intermediate iron oxide formed competing processes oxidation crystal growth after decomposition ferrous ferric salts. first step synthesized around 16 ± 4 nm, second coating 18 3 nm final C18 56 6...
The present paper depicts a novel method based on magnetic SPE (MSPE) for the determination of organophosphorus pesticides (OPs) such as phorate, malathion, and chlorpyrifos in environmental water samples. In this study, C18 functionalized silica-coated core-shell iron oxide nanoparticles (MNPs) were used surface-engineered sorbent selective extraction from aqueous samples, followed by GC-MS GC-tandem MS analysis confirmative analytes. Various important parameters, including quantity MNP...
The study deals with the facile synthesis of catenated nanosulfur by entrapping elemental sulfur polyethylene glycol 400 help bottom up approach. synthesized was studied transmission electron microscope (TEM), x-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), Raman and thermogravimetric analysis (TGA). average size about 35.5 ± 8.5 nm which confirmed TEM distribution curve fitted Gaussian model. XRD shows that crystalline in nature. FTIR PEG encapsulated over...
The potential use of chitosan/poly(styrene sulfonate) (CHS/PSS) polyelectrolyte multilayer (PEM) membranes functionalized with tannic acid (TA) and campesterol (CHT) for efficient separation recycling lithium from aqueous matrix under ultrafiltration conditions are examined. PEM assembled via layer by (LbL) method accelerates the process as it efficiently separates metal complexed larger molecules. A total eight CHS/PSS bilayers were sufficient effective recovery. microscopic studies...
