Oxidative Dissolution of Biogenic Uraninite in Groundwater at Old Rifle, CO (vol 45, pg 8748, 2011)

Elena Suvorova Buffat, Rizlan Bernier-Latmani, Harish Veeramani

Amer Chemical Soc2012

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

Elena Suvorova Buffat, Rizlan Bernier-Latmani, 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 ...

Uranium speciation and stability after reductive immobilization in sediments

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

It has generally been assumed that the bioreduction of hexavalent uranium in groundwater systems will result in the precipitation of immobile uraninite (UO2). In order to explore the form and stability of uranium immobilized under these conditions, we intr ...

Role of proteins in the controlling selenium nanoparticle size

Elena Suvorova Buffat, Rizlan Bernier-Latmani, Jan Dobias

This work investigates the potential for harnessing the association of bacterial proteins to biogenic selenium nanoparticles (SeNPs) to control the size distribution and the morphology of the resultant SeNPs. We conducted a proteomic study and compared pro ...

TEM study of Mg distribution in micrite crystals from the Mishrif reservoir Formation (Middle East, Cenomanian to Early Turonian)

Philippe Buffat, Elena Suvorova Buffat

Microporous limestones composed of micrite crystals constitute sizeable hydrocarbon reservoirs throughout the world and especially in the Middle East. However, the crystallization history of micrites is poorly understood. Scanning electronic microscopy (SE ...

Oxidative dissolution of biogenic uraninite in groundwater at Old Rifle, CO

Elena Suvorova Buffat, Rizlan Bernier-Latmani, Harish Veeramani

Reductive bioremediation is currently being explored as a possible strategy for uranium-contaminated aquifers such as the Old Rifle site (Colorado). The stability of U(IV) phases under oxidizing conditions is key to the performance of this procedure. An in ...

Non-uraninite products of microbial U(VI) reduction

Elena Suvorova Buffat, Rizlan Bernier-Latmani, Harish Veeramani, Elena Cristina Dalla Vecchia, Jonathan Sharp, Nicholas Wigginton

A promising remediation approach to mitigate subsurface uranium contamination is the stimulation of indigenous bacteria to reduce mobile U(VI) to sparingly soluble U(IV). The product of microbial uranium reduction is often reported as the mineral uraninite ...

U(VI) reduction by spores of Clostridium acetobutylicum

Elena Suvorova Buffat, Rizlan Bernier-Latmani, Harish Veeramani, Elena Cristina Dalla Vecchia, Nicholas Wigginton

Vegetative cells of Clostridium acetobutylicum are known to reduce hexavalent uranium (U(VI)). We investigated the ability of spores of this organism to drive the same reaction. We found that spores were able to remove U(VI) from solution when H, was provi ...

The effect of competing electron acceptors on U(VI) reduction by Desulfotomaculum reducens

Elena Suvorova Buffat, Rizlan Bernier-Latmani

Taylor & Francis2010

U(VI) reduction by Desulfotomaculum reducens

Manganese incorporation into biogenic uraninite affects its oxidative stability

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

2009

Transmission electron microscopy of Ca oxide nano- and microcrystals in alpha-tricalcium phosphate prepared by sintering of beta-tricalcium phosphate

Philippe Buffat, Elena Suvorova Buffat

Transmission electron microscopy (TEM) and X-ray diffraction (XRD) were used to study the porous and non-porous alpha-tricalcium phosphate (alpha-Ca-3(PO4)(2), alpha-TCP) prepared through a sintering procedure at 1200-1400 degrees C of beta-tricalcium phos ...
