Manganese-zinc-ferrite nanoparticles (Mn(0.5)Zn(0.5)Fe(2)O(4), MZF-NPs) prepared by an improved co-precipitation method and were characterized by transmission electron microscopy (TEM), X-ray diffraction (XRD) and energy dispersive spectrometry (EDS). Then thermodynamic testing of various doses of MZF-NPs was performed in vitro. The cytotoxicity of the Mn(0.5)Zn(0.5)Fe(2)O(4) nanoparticles in v...

although micronutrients effect on growth and yield of different plants has been intensively investigated, but there is limited information on its effect on grain yield and seed oil content of pot marigold) calendula officinalis l.). in order to investigate the effects of micronutrients (fe, zn and mn) spraying on yield and yield components and seed oil of pot marigold, a field experiment was co...

PURPOSE To explore the preparation and characterization of a novel nanosized magnetic liposome containing the PEI-As(2)O(3)/Mn(0.5)Zn(0.5)Fe(2)O(4) complex. METHODS Mn(0.5)Zn(0.5)Fe(2)O(4) and As(2)O(3)/Mn(0.5)Zn(0.5)Fe(2)O(4) nanoparticles were prepared by chemical coprecipitation and loaded with PEI. The PEI- As(2)O(3)/Mn(0.5)Zn(0.5)Fe(2)O(4) complex was characterized using transmission ele...

in the present investigation flocculation of dissolved cu, zn, pb, ni and mn in a series of mixtures with salinities ranging from 1.5 to 9.5% during mixing of talar river water with the caspian sea water was studied. the flocculation trend of zn (87.22%) >mn (45.31%) >pb (39.09%) >cu (36.58%)>ni (12.70%) indicates that cu, zn, pb and mn have non-conservative behavior and ni has relatively conse...

this study was carried out to determination of in vitro binding capacity of organic (wheat and barley) and inorganic (perlite) sources for mn, zn, cu, and fe. for this reason wheat and barley were analyzed chemically for moisture, protein, ash, and ether extract, total carbohydrate, ndf, adf, adl, crude fiber, viscosity, cellulose, and total dietary fiber. the in vitro mineral binding capacity ...

A better understanding of the role of the Arabidopsis ZIP family of micronutrient transporters is necessary in order to advance our understanding of plant Zn, Fe, Mn, and Cu homeostasis. In the current study, the 11 Arabidopsis ZIP family members not yet well characterized were first screened for their ability to complement four yeast mutants defective in Zn, Fe, Mn, or Cu uptake. Six of the Ar...

We propose to replace Ga in (Ga,Mn)As with Li and Zn as a route to high Curie temperature, carrier mediated ferromagnetism in a dilute moment n-type semiconductor. Superior material characteristics, rendering Li(Zn,Mn)As a realistic candidate for such a system, include high solubility of the isovalent substitutional Mn impurity and carrier concentration controlled independently of Mn doping by ...

to determine the effect of zn and mn enriched seed on quality of two winter safflower varieties under drought stress, an experiment was conducted at the agricultural faculty research field, tarbiat modarres university, during 2004-2005 cropping season. the design was a split factorial randomized complete block one of 3 replications. main plots were composed of 3 different levels of drought stre...
