Facile Synthesis, Static, and Dynamic Magnetic Characteristics of Varying Size Double-Surfactant-Coated Mesoscopic Magnetic Nanoparticles Dispersed Stable Aqueous Magnetic Fluids.

The present work reports the synthesis of a stable aqueous magnetic fluid (AMF) by dispersing double-surfactant-coated FeO magnetic nanoparticles (MNPs) in water using a facile ambient scalable wet chemical route. MNPs do not disperse well in water, resulting in low stability. This was improved by dispersing double-surfactant (oleic acid and sodium oleate)-coated MNPs in water, where cross-linking between the surfactants improves the stability of the AMFs.

Development of polyclonal antibodies using bacterially expressed recombinant coat protein for the detection of (OYDV) and identification of virus free onion genotypes.

Onion yellow dwarf virus (OYDV) belonging to the genus , family is one of the widely distributed viruses of species worldwide. It causes dwarfing, yellow striping, crinkling and flaccidity of the leaves of onion and garlic. To see the occurrence and incidence of OYDV on crop, an attempt was made to develop antibody based diagnostic assay which would be useful for routine indexing and screening of the germplasm.

NTCDA-TTF first axial fusion: emergent panchromatic, NIR optical, multi-state redox and high optical contrast photooxidation.

The first synthetic entry into axially fused NTCDA/PMDA-TTF multipolar molecules demonstrates a high optical contrast photooxidation, panchromism, low HOMO-LUMO gap, generation of a stable radical cation, NIR absorption/emission beyond 2150/800 nm and theoretically calculated NLO activity.
