Aqueous contaminant removal in the presence of metallic iron (e.g. in Fe(0)/H(2)O systems) is characterized by the large diversity of removing agents. This paper analyses the synergistic effect of adsorption, co-precipitation and reduction on the process contaminant removal in Fe(0)/H(2)O systems on the basis of simple theoretical calculations. The system evolution is characterized by the perce...

Mutualisms often involve one host supporting multiple symbionts, whose identity, density and intraguild interactions can influence the nature of the mutualism and performance of the host. However, the implications of multiple co-occurring symbionts on services to a host have rarely been quantified. In this study, we quantified effects of decapod symbionts on removal of sediment from their coral...

background & aims of the study: heavy metals are the most important and main pollutants because of their accumulation and high toxicity even at very low dose and cause serious hazards to ecological system as well as human health. thus, their removal has been challenged from drinking water and industrial waters with different technologies. the purpose of this work is to investigate the removal o...

Eleven flavoproteins from the old yellow enzyme family were found to catalyze the disproportionation ("dismutation") of conjugated enones. Incomplete conversions, which were attributed to enzyme inhibition by the co-product phenol could be circumvented via in situ co-product removal by scavenging the phenol using the polymeric adsorbent MP-carbonate. The optimized system allowed to reduce an al...

Carbon dioxide removal (CDR) has become a focal point for legislators and policymakers who are pursuing strategies climate change mitigation. This paper employs policy framework of collective biophysical need to examine two broad categories CDR methods being subsidized advanced by the United States other countries: mechanical capture biological sequestration. Using published data on these metho...

The α6 nicotinic acetylcholine receptor (nAChR) subunit is an attractive drug target for treating nicotine addiction because it is present at limited sites in the brain including the reward pathway. Lynx1 modulates several nAChR subtypes; lynx1-nAChR interaction sites could possibly provide drug targets. We found that dopaminergic cells from the substantia nigra pars compacta (SNc) express lynx...

Aboveground litter production in forests is likely to increase as a consequence of elevated atmospheric carbon dioxide (CO(2)) concentrations, rising temperatures, and shifting rainfall patterns. As litterfall represents a major flux of carbon from vegetation to soil, changes in litter inputs are likely to have wide-reaching consequences for soil carbon dynamics. Such disturbances to the carbon...

Abstract: CO2 is one of the most important greenhouse gases and its removal from flue gas and natural gas has become increasingly important. We report the synthesis, characterization, and CO2 adsorption properties of two similar metal organic frameworks; Co and Ni based MOF-74. The BET specific surface areas of MOF-74(Co) and MOF-74(Ni) MOFs were 1,406 and 1,418 mg, respectively with the identi...
