Sorption of actinides, particularly plutonium, onto submicrometer-sized colloids increases their mobility, but these plutonium are difficult to detect in the far-field. We identified actinides on groundwater from Mayak Production Association, Urals, Russia; at source, activity is approximately 1000 becquerels per liter. Plutonium activities still 0.16 liter a distance 3 kilometers, where 70 90 mole percent sorbed colloids, confirming that responsible for long-distance transport plutonium....
The goal of the present work was to investigate physicochemical and radiochemical conditions composition microbial community in groundwater a suspended surface repository for radioactive waste (Russia) determine possibility situ bioremediation by removal nitrate ions. Groundwater area (10-m depth) had elevated concentrations strontium, tritium, nitrate, sulfate, bicarbonate High-throughput sequencing V3-V4/V4 region 16S rRNA gene revealed presence members phyla Proteobacteria (genera...
We measured the Raman spectra of ferromagnetic nearly half metal CoS2 in a broad temperature range. All five active modes Ag, Eg, Tg(1), Tg(2) and Tg(3) were observed. The magnetic ordering is indicated by change dependences frequency line width Ag T g(2) at Curie point. dependence frequencies linewidths paramagnetic phase can be described framework Klemens approach. Hardening Tg(2), Tg(1) A g on cooling unambiguously seen phase. behave natural way low exciting laser power (decrease with...
Actinides in their higher valence states (e.g., MO2+ and MO22+, where M can be Np, Pu, etc) possess a potential for migration turn pose substantial environmental threat. To minimize this migration, reducing them to lower oxidation tetravalent state) an attractive efficient remedial process. These are often much less soluble natural aqueous media are, therefore, mobile the environment. The research presented here focuses on assessing performance of quinonoid-enriched humic derivatives with...

The speciation of plutonium and neptunium in colloid suspension collected from the contaminated aquifer “Mayak” site was studied by nano-SIMS, XPS XANES. At tracer level concentration found original groundwater sample Pu is sorbed onto hydrous ferric oxide colloids, while at higher relevant to near-field conditions it forms intrinsic PuO2 × nH2O colloids. formation such colloids occurs through reduction Pu(V) Pu(IV) upon its sorption.
We report photoluminescence studies of micro-and nano-sized diamonds with NV 0 , -and SiV -centers under hydrostatic pressure up to 50 GPa.Diamonds have been obtained by high-pressure high-temperature (HPHT) treatment metal-free growth systems based on mixtures hydrocarbon, fluorocarbon, and silicone-containing organic compounds.
The possible role of biogeochemical processes in the transport colloidal and pseudo-colloidal U, Np, Pu during bioremediation radionuclide- nitrate-contaminated groundwater was investigated. In two laboratory experiments with water samples taken from contaminated aquifers before post bioremediation, we found that microbial could cause clayed, ferruginous, actinide colloids to coagulate. main mechanisms are biogenic insoluble ferrous iron species formations (goethite, pyrrhotite, siderite,...
The goal of the present work was to investigate physicochemical and radiochemical conditions microbial diversity in groundwater collected near Lake Karachai (Russia), which formerly used for disposal liquid radioactive waste, isolate dominant bacteria, determine their taxonomy physiological characteristics responsible adaptation this environment. Groundwater samples contained high concentrations acetate, oxalate, nitrate, sulfate, as well radionuclides. High-throughput sequencing analysis...
ABSTRACT The mass transfer of Eu(III) Tb(III),Am(III)and Cm(III)through HDEHP solid supported liquid membranes has been studied. best experimental conditions to perform Am(III)-Cm(III),Eu(III)-Tb(III)and Eu(III)-Am(III) separation have found. coefficients the above mentioned pairs determined be equal 5.0, 10.8 and more then 102, respectively.
