Iron oxid oxide magnetic nanoparticles with biocompatibility and functional coatings via appropriate surface chemistry approaches have been used for immobilization of cells, proteins, enzymes,antibodies, oligonucleotides and drugs through covalent bonding or adsorption.

氧化铁磁性纳米粒子可以通过多种方法制备得到，通过表面化学修饰可以得到无机SiO2包覆的核壳结构的复合磁性纳米粒子。

Once delivered to the heart, injected cells are difficult to distinguish from target tissue by MR in vivo.To specifically imaging injected cells in MR, the recent investigation generally using superparamagnetic iron oxid to label MSCs, which should enable serial tracking and quantification of MSC transplantation noninvasively by MR.

由于MR成像无法区分移植细胞和靶组织细胞，为使移植细胞能在MR上特异性显示，目前广泛使用超顺磁性氧化铁(superparamagnetic iron oxid， SPIO)作为负性标记物标记移植细胞，进行MR体外和活体内的成像研究。

Disposal on methyl orange solution by two kinds of nanometer sized iron oxyhydroxides:α-FeOOH and β-FeOOH in visible light showed that methyl orange solution decolored by 90% by FeOOH/H2O2 system.And phenyl in methyl orange molec...

用2种纳米氧氢氧化铁针铁矿，正方纤铁矿处理偶氮染料分子甲基橙溶液，在自然光下，FeOOH/H2O2体系能使甲基橙溶液脱色率达90%，并且能将甲基橙分子中的苯环部分打开。

The oxidizing substance like iron oxide existed everywhere on the Mars,so the Oxygen can be deoxidized.

火星上到处都是氧化铁等氧化物质，可还原出氧气来。

Since FeO is more stable than Cu2O, the FeS is oxidized in preference to Cu2S and the FeO formed is fluxed with SiO2 to form iron silicate slag.

由于 FeO 比 Cu2O 更稳定，因此 FeS 优先于 Cu2S 氧化，形成的氧化铁与二氧化硅熔融形成硅酸铁渣。

The major driving force promoting the formation of iron nodules is in situ weathering from saprolites by frequently alternating wetting/drying cycles, while illuviated iron only played a minor role in this formation.

本研究中生成铁瘤的主要机制乃是腐石在原处经频繁变动的乾湿交替作用后，崩解风化而化育生成，而洗入型的氧化铁则为生成铁瘤的次要力量。
