Two recent papers in Nature, Ben-Zvi et al. (2014) and Nguyen et al. (2014), report a surprising dual role for the blood-brain barrier transporter MFSD2A in both establishing BBB integrity and in uptake of the fatty acid DHA.

Direct interspecies electron transfer (DIET), which does not involve mediation by carriers, is realized the addition of conductive materials to an anaerobic digester, then activates syntrophism between acetogenic and methanogenic microorganisms. This study aimed investigate effect two materials, zero-valent iron (ZVI) magnetite, on methane production microbial consortium via DIET in digestion f...

The presence of anglesite (PbSO4) in complex sulfide ores negatively affects the separation Cu-Pb sulfides and sphalerite (ZnS) due to lead activation, PbSO4 rejected tailings dams contaminates surrounding environment with lead. To address these problems, this study investigated application ethylene diamine tetra acetic acid (EDTA) pretreatment extracting ZnS flotation recovery extracted Pb2+ a...

The present work was conducted for Arsenic (III) removal, which one of the most poisonous groundwater pollutants, by synthetic nano size zerovalent iron (nZVI). Batch experiments were performed to investigate the influence of As (III), nZVI concentration, pH of solution and contact time on the efficiency of As (III) removal. nZVI was synthesized by reduction of ferric chloride by sodium borohyd...

At present, the use of water in each country increases sharply, which also brings increasingly prominent environmental pollution problems. A large amount wastewater is discharged into body, seriously pollutes environment. Wastewater treatment has become focus global protection workers. Among them, advanced oxidation technology based on sulfate radical used to treat refractory organic pollutants...

Abstract Zerovalent (ZVI) iron has been used in environmental remediation, but the fate of its nanoparticles (NZVI) is hard to find. The present study aimed characterise adsorption processes commercial ZVI inorganic fraction volcanic soils, contributing knowledge process on whole soil. Volcanic soil samples were obtained by calcination method and characterised. A nano-ZVI stable suspension prep...

diazinon pesticide and its metabolites have been identified in aquatic systems worldwide. it was related to toxicity for aquatic organisms, animals, and humans. waters contaminated with such persistent insecticides should be treated with suitable treatment processes. in this research, diazinon removal from aqueous solutions by the photo–fenton–like process (uv/h2o2/fe0) was investigated. this e...

The management of mature landfill leachate (MLL) represents an increasingly crucial issue to tackle. In this study, the feasibility integrated treatment was investigated at laboratory scale using synthetic with objective maximizing recovery potentially useful compounds present in (especially ammonia nitrogen). First, order remove heavy metals, active filtration MLL carried out zero-valent iron ...

Polluted aquifers can be decontaminated using either ZVI (zero valent iron) permeable reactive barriers (PRB) or injected ZVI. The placement of within the aquifer may take several decades to remediate contaminant plume. Remediation is further complicated by acting as an adsorbent remove some pollutants, while for other it acts a remediation catalyst. This study investigates alternative decontam...
