Two new hydrido iron complexes (2 and 4) were synthesized by the reactions of (4-methoxyphenyl)phenylketimine ((4-MeOPh)PhC=NH) with Fe(PMe3)4 or FeMe2(PMe3)4. The molecular structures of complexes 2 and 4 were confirmed by X-ray single crystal diffraction. Using hydrido iron complexes (1-4) as catalysts, the hydrosilylations of aldehydes and ketones were investigated. The four complexes were e...

Acaeruloplasminaemia is characterized by excessive neurovisceral iron accumulation due to mutation of the caeruloplasmin gene. Excess iron functions as a potent catalyst of biological oxidation, and increased iron concentration is associated with the products of lipid peroxidation in the serum and cerebrospinal fluid. We investigated whether the amount of iron accumulated paralleled lipid perox...

Multiple sclerosis (MS) and its animal model, experimental allergic encephalomyelitis (EAE), are autoimmune disorders resulting in demyelination in the central nervous system (CNS). Pathologically, the blood-brain barrier becomes damaged, macrophages and T cells enter into the CNS, oligodendrocytes and myelin are destroyed, astrocytes and microglia undergo gliosis, and axons become transected. ...

The presence of 10 mM sodium molybdate has a profound effect on the physical behavior of glucocorticoid receptors submitted to ammonium sulfate precipitation or to DEAE-cellulose chromatography. Molybdate inhibits the inactivation of the unoccupied receptor and prevents the transformation of the steroid-bound receptor that occurs when rat liver cytosol is precipitated with ammonium sulfate. The...

The Stober process is frequently used to prepare silica-coated iron oxide nanoparticles. This is usually achieved by seeding a reaction mixture consisting of water, ethanol and a catalyst with iron oxide particles and adding a silica precursor. The hydrolysis and condensation of precursor monomers results in the deposition of a silica layer on iron oxide particles. However, this process is acco...

Fischer–Tropsch process (F-T) is an efficient technology to synthesize liquid transportation fuel as well as other valuable chemicals. This process is associated with hydrogenation of carbon monoxide gas in presence of transition metal catalyst to valuable liquid transportation fuels and chemicals. F-T reaction is essentially a catalytic process, and most widely used catalysts are either iron o...

Colloidal synthesis routes have been recently used to fabricate heterogeneous catalysts with more controllable and homogeneous properties. Herein a method was developed to modify the surface composition of colloidal nanocrystal catalysts and to purposely introduce specific atoms via ligands and change the catalyst reactivity. Organic ligands adsorbed on the surface of iron oxide catalysts were ...
