Screening of Solanum tuberosum cultivars for the 'ac2' genetic modification

Autor: R. Pribylova, J. Ptacek, I. Pavlik, M. Bartos

Publikováno v: Veterinární Medicína, Vol 52, Iss 11, Pp 471-474 (2007)

In 2001, genetically modified potatoes carrying the ac2 gene were developed. This gene was originally found in amaranth seeds (Amaranthus caudatus) and is expressed into the fungicidal peptide Ac-AMP2. The purpose of the present study was to test 105

Improved precision in As speciation analysis with HERFD-XANES at the As K-edge: the case of As speciation in mine waste

Autor: Emily M. Saurette, Y. Zou Frinfrock, Brent Verbuyst, David W. Blowes, Joyce M. McBeth, Carol J. Ptacek

Publikováno v: Journal of Synchrotron Radiation, Vol 29, Iss 5, Pp 1198-1208 (2022)

High-energy-resolution fluorescence-detected (HERFD) X-ray absorption near-edge spectroscopy (XANES) is a spectroscopic method that allows for increased spectral feature resolution, and greater selectivity to decrease complex matrix effects compared

Sphalerite weathering and controls on Zn and Cd migration in mine waste rock: An integrated study from the molecular scale to the field scale

Autor: Zhongwen Bao, David W. Blowes, Tom A. Al, Jeff Bain, Y. Zou Finfrock, Heather K. Shrimpton, Carol J. Ptacek

Publikováno v: Geochimica et Cosmochimica Acta. 318:1-18

Degraded water quality and environmental impacts caused by weathering of sulfide-bearing mine wastes are a legacy remaining at many historical mine sites. Release and mobilization of toxic metals (e.g., Zn and Cd) in mine drainage are often associate

Nickel isotope fractionation during precipitation of Ni secondary minerals and synchrotron-based analysis of the precipitates

Autor: Joel Reid, David W. Blowes, Ning Chen, Roberta Parigi, Carol J. Ptacek

Publikováno v: Geochimica et Cosmochimica Acta. 317:91-105

The determination of fractionation factors associated with important biogeochemical processes controlling Ni availability in the environment is necessary to confidently use Ni isotope signatures as tracers in environmental studies. In this paper we p

Mineralogy-dependent sulfide oxidation via polysulfide and thiosulfate pathways during weathering of mixed-sulfide bearing mine waste rock

Autor: Y. Zou Finfrock, Emily Saurette, Jeff Bain, Carol J. Ptacek, David W. Blowes, Yongfeng Hu, Zhongwen Bao

Publikováno v: Geochimica et Cosmochimica Acta. 317:523-537

Tracking the S oxidation pathway in sulfide-bearing mine waste-rock piles is complicated by variations in water content, O2 and Fe3+ concentrations, microbial diversity, mineralogy, the occurrence of a variety of S species associated with incomplete
