Ocean acidification is expected to have a major effect on the marine carbonate system over the next century, particularly in high latitude seas. Less appreciated is natural environmental variation within these systems, particularly in terms of pH, and how this natural variation may inform laboratory experiments. In this study, we deployed sensor-equipped moorings at 20 m depths at three locatio...

Background: There are great resources of natural zeolite in Iran. Zeolite, an inorganic ion-exchanger, may be used as a suitable technical-economical solution for water treatment in many regions of Iran. In this study, the characterization of natural zeolite natrolite and the feasibility of removing hardness, cations, and anions were investigated. Methods: First, zeolite composition and type we...

The efficacy of gliding arc (GA) discharge for the generation of hydrogen peroxide (H2O2) and water with a low pH was studied because H2O2 combined with low-pH environment is known as a strong oxidizer that can be used for the bacterial inactivation. The ability of the GA discharge to inactivate Escherichia coli in water was tested experimentally, and the inactivation was found to increase with...

1. Increased water intake and output is more common among psychiatric patients, especially those with schizophrenia, than in the general population. Animal studies suggest that polydipsia and polyuria derive, in part, from dopamine dysregulation. Stimulated by these observations this study sought to elucidate relationships among water homeostasis, monoamine metabolism, and electrolyte excretion...

Development of efficient, robust and earth-abundant water oxidation catalysts (WOCs) is extremely desirable for water splitting by electrolysis or photocatalysis. Herein, we report cobalt oxide nanoparticles anchored on the surface of sulfonated graphite (denoted as “CoOx@G-Ph-SN”) to exhibit unexpectedly efficient water oxidation activity with a turnover frequency (TOF) of 1.2 s ; two or three...

Heavy metal, chromium (VI) removal by coagulation using natural coagulant material was investigated in this paper. Chromium occurs naturally in the paint manufacturing industry waste water in many steps of the process. The coagulation and flocculation method is used for chromium removal from waste water using fruits of Opuntia Ficus indica, Fruits of Jatropha gossypifolia and peel of Borassus f...
