Products of abiotic U(VI) reduction by biogenic magnetite and vivianite

Rizlan Bernier-Latmani, Elena Suvorova Buffat, Harish Veeramani, Jonathan Sharp, Daniel Scott Alessi

Reductive immobilization of uranium by the stimulation of dissimilatory metal-reducing bacteria (DMRB) has been investigated as a remediation strategy for subsurface U(VI) contamination. In those environments, DMRB may utilize a variety of electron accepto ...

Magnetic Decoupling of Surface Fe3+ in Magnetite Nanoparticles upon Nitrocatechol-Anchored Dispersant Binding

Esther Amstad

Bind and distort: NitroDOPA, an anchor shown to irreversibly couple dispersants and functional groups to superparamagnetic Fe 3O 4 nanoparticles, can magnetically decouple Fe 3+ in a nanoparticle surface layer. The strong binding of nitroDOPA distorts the ...

An Iron Carbonyl Pyridonate Complex Related to the Active Site of the [Fe]-Hydrogenase (Hmd)

Rosario Scopelliti, Xile Hu, Blaise Valentin Obrist, Dafa Chen

A mononuclear iron bis(carbonyl) pyridonate complex (1), which exhibits several common structural features with the active site of the iron−sulfur cluster-free [Fe]- hydrogenase, was synthesized and characterized. Spectroscopic data of 1 suggests a 2+ oxid ...

Ionic solid-state dimers and polymers derived from imidazolium dicarboxylic acids

Paul Joseph Dyson, Zhaofu Fei, Wee Han Ang

A series of imidazolium dicarboxylic acids have been prepd. from the reaction of the 1,3-bis(carboxymethyl)imidazolium zwitterion with the Bronsted acids HX (X = F, Br, Cl, ClO4). The structures of these acids have been established in the solid ...

Chemistry and biology of Anachelin and derivatives

Iron is an essential nutrient for virtually all forms of life. To overcome its extreme insolubility, many microbes synthesize and excrete powerful iron-selective chelating agents, so-called siderophores. Anachelin H (A) was recently isolated from the cyano ...
