The algal toxicity of silver engineered nanoparticles and detoxification by exopolymeric substances.
TLDR
The secretion of polysaccharide-rich algal exopolymeric substances (EPS) significantly increased at increasing [Ag(+)](F), suggesting that EPS may be involved in Ag(+) detoxification. Expand
Translocation and biotransformation of CuO nanoparticles in rice (Oryza sativa L.) plants.
TLDR
Metal-based nanoparticles may be translocated and biochemically modified in vivo, which may influence the fate of MNPs in the environment and bulk-XANES data showed that CuO NPs were transported from the roots to the leaves, and that Cu (II) combined with cysteine, citrate, and phosphate ligands and was even reduced to Cu (I).

Iodine-129 and iodine-127 speciation in groundwater at the Hanford site, US: iodate incorporation into calcite.
TLDR
The common sampling artifact resulting in the precipitation of calcite by degassing CO2, had the unintended consequence of providing insight into a potential solution for the in situ remediation of groundwater (129)I. Expand
Evaluation of a radioiodine plume increasing in concentration at the Savannah River Site.
TLDR
Groundwater monitoring of the plume at the basins has shown that the migration of many of the high risk radionuclides originally present at this complex site has been attenuated, however, (129)I continues to leave the source at a rate that may have been exacerbated by the initial remediation efforts. Expand
Novel molecular-level evidence of iodine binding to natural organic matter from Fourier transform ion cyclotron resonance mass spectrometry.
TLDR
Electrospray ionization coupled to Fourier transform ion cyclotron resonance mass spectrometry (ESI-FTICR-MS) was applied to elucidate the interactions between inorganic iodine species (iodide and iodate) and a fulvic acid (FA) extracted from a SRS surface soil and provides novel evidence to better understand the reactivity and scavenging properties of NOM towards radioiodine and possible influence of N OM on (129)I migration. Expand
Natural organic matter-induced alleviation of the phytotoxicity to rice (Oryza sativa L.) caused by copper oxide nanoparticles.
TLDR
The results showed that CuO NPs induced the inhibition of root elongation, aberrations in root morphology and ultrastructure, and losses of cell viability and membrane integrity, and all the phytotoxicity was alleviated with the addition of humic acid. Expand
Onsite bio-detoxification of steam-exploded corn stover for cellulosic ethanol production.
In the process of ethanol production from steam-exploded corn stover (SECS), a cellulose-degradation strain of Aspergillus nidulans (FLZ10) was investigated whether it could remove the inhibitorsExpand
Scavenging and fractionation of thorium vs. protactinium in the ocean, as determined from particle–water partitioning experiments with sediment trap material from the Gulf of Mexico and Sargasso Sea
Abstract Particle–water partition coefficients (Kd) for thorium (Th) and protactinium (Pa) were calculated for sediment trap material collected from the Gulf of Mexico (GOM) in the upper 140 m andExpand
An Adaptive IR-HARQ Scheme for Polar Codes by Polarizing Matrix Extension
TLDR
This letter shows that an arbitrary number of incremental coded bits can be generated by extending the polarizing matrix, such that multiple retransmissions are aggregated to produce a longer polar code with extra coding gain. Expand
Pharmacokinetics of oral and intravenous cannabidiol and its antidepressant-like effects in chronic mild stress mouse model.
TLDR
The antidepressant-like effects of periodically administered CBD on the chronic mild stress mouse model are evaluated and are expected to provide a reference for the development of intravenous antidepressant formulations of CBD. Expand
