Effect of chemical structure on the sonochemical degradation of perfluoroalkyl and polyfluoroalkyl substances (PFASs)
- N. Fernández, Lucia Rodriguez-Freire, M. Keswani, R. Sierra-Álvarez
- Chemistry
- 10 November 2016
Perfluoroalkyl surfactants include chemicals characterized by a fully fluorinated carbon chain (hydrophobic and oleophobic tail) bound to a hydrophilic head (a carboxyl or sulfonic group). These… Expand
Flexible bacterial strains that oxidize arsenite in anoxic or aerobic conditions and utilize hydrogen or acetate as alternative electron donors
- Lucia Rodriguez-Freire, W. Sun, R. Sierra-Alvarez, J. Field
- Chemistry, Medicine
- Biodegradation
- 1 February 2012
Arsenic is a carcinogenic compound widely distributed in the groundwater around the world. The fate of arsenic in groundwater depends on the activity of microorganisms either by oxidizing arsenite… Expand
Biomineralization of arsenate to arsenic sulfides is greatly enhanced at mildly acidic conditions.

- 30 December 2015
Perfluoooctanesulfonic acid (PFOS) is a perfluorinated compound (PFC) highly resistant to conventional advance oxidation processes, which was widely used in industrial activities due to its… Expand
Arsenic remediation by formation of arsenic sulfide minerals in a continuous anaerobic bioreactor
- Lucia Rodriguez-Freire, S. E. Moore, R. Sierra-Alvarez, R. Root, J. Chorover, J. Field
- Chemistry, Medicine
- Biotechnology and bioengineering
- 1 March 2016
Arsenic (As) is a highly toxic metalloid that has been identified at high concentrations in groundwater in certain locations around the world. Concurrent microbial reduction of arsenate (AsV) and… Expand
Effect of Calcium on the Bioavailability of Dissolved Uranium(VI) in Plant Roots under Circumneutral pH.
- Eliane El Hayek, C. Torres, +7 authors J. Cerrato
- Chemistry, Medicine
- Environmental science & technology
- 9 November 2018
We integrated field measurements, hydroponic experiments, microscopy, and spectroscopy to investigate the effect of Ca(II) on dissolved U(VI) uptake by plants in 1 mM HCO3- solutions at circumneutral… Expand
Uranium mobility and accumulation along the Rio Paguate, Jackpile Mine in Laguna Pueblo, NM.

- 19 April 2017
The mobility and accumulation of uranium (U) along the Rio Paguate, adjacent to the Jackpile Mine, in Laguna Pueblo, New Mexico was investigated using aqueous chemistry, electron microprobe, X-ray… Expand
Sonochemical degradation of perfluorinated chemicals in aqueous film-forming foams.
- Lucia Rodriguez-Freire, Nerea Abad-Fernández, +5 authors M. Keswani
- Chemistry, Medicine
- Journal of hazardous materials
- 5 November 2016
Aqueous film-forming foams (AFFFs) are complex mixtures containing 1-5% w/w fluorocarbons (FCs). Here, we have investigated degradation of two commercial AFFF formulations, 3M and Ansul, using sound… Expand
