Note on Colloidal Ferric Hydroxide in Sea Water
If a sol of colloidal ferric hydroxide is added to sea water, or if the hydroxide is formed in sea water by adding a solution of an iron salt, the aggregated molecules of hydroxide coalesce to form flocs which fall rather rapidly as a precipitate. When several thousand mg. of iron are added per cubic metre of sea water, flocculation is immediate; on adding 300-500 mg. Fe per m.3 in sufficiently...
متن کاملNano-Ferric Oxide Promotes Watermelon Growth
With the rapid growing of nanotechnology, the effects of nanomaterials released into the environment on plants have drawn more and more attention. Iron is an element essential for plant growth and development. Iron is involved in chlorophyll formation; iron deficiency will cause a plant disorder known as chlorosis. However, whether iron in nano-ferric oxide can be absorbed by plants were rarely...
متن کاملMagnetotactic bacteria form magnetite from a phosphate-rich ferric hydroxide via nanometric ferric (oxyhydr)oxide intermediates.
The iron oxide mineral magnetite (Fe3O4) is produced by various organisms to exploit magnetic and mechanical properties. Magnetotactic bacteria have become one of the best model organisms for studying magnetite biomineralization, as their genomes are sequenced and tools are available for their genetic manipulation. However, the chemical route by which magnetite is formed intracellularly within ...
متن کاملNitric oxide binding to ferric cytochrome P450: a computational study.
The interaction between nitric oxide (NO) and the active site of ferric cytochrome P450 was studied by means of density functional theory (DFT), at the generalized gradient approximation level, and of the SAM1 semiempirical method. The electrostatic effects of the protein environment were included in our DFT scheme by using a hybrid quantum classical approach. The active-site model consisted of...
متن کاملPreparation of surface modified magnetic Iron Oxide nanoparticles and study of their colloidal behavior
In this work, we report synthesis of surface modified superparamagnetic iron oxide nanoparticles (SPION) by co-precipitation method using FeSO4.7H2O and Fe2(SO4)3.5H2O as precursors and trisodium citrate dihydrate as surfactant. Surface modification of the as prepared samples was performed in pot by sol-gel precipitation method u...
