Magnetite nanoparticle (NP) uptake by wheat plants

2016-9-15  In addition, magnetite NPs enhanced the root elongation of rye grass and pumpkin plants, possibly due to dissolved iron ions from magnetite serving as nutrients (Wang et al., 2011). In contrast, in this work, no significant stimulating or marked deleterious effects were observed in wheat seedlings exposed to increasing concentrations of a fine powder of citrate-coated magnetite NPs, although

Physiological effects of magnetite (Fe3O4)

This study was focused on revealing some of the physiological effects of magnetite (Fe (3)O (4)) NPs on perennial ryegrass (Lolium perenne L.) and pumpkin (Cucurbita mixta cv. white cushaw) plants under hydroponic conditions.

Magnetite nanoparticle (NP) uptake by wheat plants

2016-9-15  However, when magnetite NPs (1000mgkg(-1)) were added, the root length of the plants increased by 25 and 50%. Cd(2+) and Cr(6+) showed similar and noninteractive joint action, but strongly impaired the wheat seedlings. In contrast, an interactive infra-additive or antagonistic effect was observed upon adding magnetite NPs.

Frontiers Magnetic field effects on plant growth

2014-9-4  The geomagnetic field (GMF) is a natural component of our environment. Plants, which are known to sense different wavelengths of light, respond to gravity, react to touch and electrical signaling, cannot escape the effect of GMF. While phototropism, gravitropism, and tigmotropism have been thoroughly studied, the impact of GMF on plant growth and development is not well-understood.

The sludge volume index (SVI) and mixed liquor suspended solids (MLSS) were also examined to ascertain the effect of the magnetite technology on these parameters. The findings showed improved SVI and increased MLSS and that the upgraded facility is successfully treating peak flows while maintaining good effluent quality.

Redox cycling of Fe(II) and Fe(III) in magnetite by Fe

2015-3-27  Iron acts as both a source and sink of electrons for microorganisms in the environment. Some anaerobic bacteria use oxidized Fe(III) as an electron acceptor, whereas phototrophic bacteria can use reduced Fe(II) as an electron donor. Byrne et al. show that the iron-bearing mineral magnetite, which contains both Fe(II) and Fe(III), can serve as both an electron acceptor and donor.
