The use of a robust optical signaling probe with a high signal-to-noise ratio is important in the development of immunoassays. Lanthanide chelates are a promising material for this purpose, which provide time-resolved luminescence (TRL) due to their large Stokes shift and long luminescence lifetime. From this, they have attracted considerable interest in the in vitro diagnostics field. However,...

The application of a variety of iron complexes with chelating amine ligands as pre-catalysts in the representative cross-coupling of 4-tolylmagnesium bromide with cyclohexyl bromide was investigated. The results from this study indicate the performance of the pre-catalyst is inversely proportional to the strength of the chelate or macrocyclic effect of the amine ligand, as determined by the pro...

Haemophilus influenzae can utilize iron-loaded human transferrin as an iron source for growth in vitro. H. influenzae tonB mutants, containing a chloramphenicol acetyltransferase gene within their tonB genes, could bind iron-charged human transferrin to their cell surfaces, but they were unable to utilize this serum glycoprotein as the sole source of iron for growth in vitro. In contrast, these...

The micro layers micaceous iron oxide and nano-TiO 2 were incorporated into the epoxy resin by mechanical mixing and sonication process. Optical micrographs showed that the number and diameter size of nanoparticle agglomerates were decreased by sonication. The structure and composition of the nanocomposite was determined using transmission electron microscopy which showed the presence of disper...

We report on the nano-electron beam assisted fabrication of atomically sharp iron-based tips and on the creation of a nano-soldering iron for nano-interconnects using Fe-filled multiwalled carbon nanotubes (MWCNTs). High energy electron beam machining has been proven a powerful tool to modify desired nanostructures for technological applications (1-4) and to form molecular junctions and interco...

BACKGROUND: Organic farming has emerged as important priority area globally in view of growing demand for safe and healthy food and long term sustainability and concerns on environmental pollution associated with indiscriminate use of agrochemicals. Nano fertilizers can be easily absorbed by crops and may exhibit a prolonged effective duration of nutrient supply in soil/crop co...

Salinity is an abiotic stressor that greatly influences crop growth and yield. Scientists are always exploring diverse methods to combat salinity depression. Here, we conducted a greenhouse experiment study the effects of NaCl (0, 50, 100 mM) under foliar spray with zinc-oxide, nano iron-chelate, magnetized-Fe, graphene-oxide on tarragon. The results revealed treatment graphene showed highest K...
