Novel electrode fabrication and reactor design for electrocatalytic nitrate and nitrite reduction in drinking water treatment
… and/or disposal, and alternatives like catalytic reduction suffer from gas-liquid mass transfer limitations that inhibit treatment performance in realistic continuous flow reactors. Electrocatalytic NO₃⁻ reduction has emerged as a promising option to overcome these shortcomings. A number of …

Development of sustainable Pd-based catalysts for removal of persistent contaminants from drinking water
Pd-based catalytic reduction has emerged as an advanced treatment technology for drinking water decontamination, and a suite of persistent contaminants including oxyanions, N-nitrosoamines, and halogenated compounds are amenable to catalytic reduction. The primary goal of this study is to develop …

Evaluation of Glycerol and Waste Alcohol as Supplemental Carbon Sources for Denitrification
… they both exhibited significant and consistent nitrite accumulation during the entire experiment. Based on reactor restart, nitrite accumulation was evident and significant within two days after startup and consistent for all further operation. Rapid nitrate to nitrite reduction coincident with …

Bio-inspired first-row transition metal complexes for small molecule activation
… of rendering these reactions catalytic, reduction of the Fe(III) complexes back to the starting Fe(II) complexes was undertaken and accomplished. This result intrigued me and led me to study the catalytic reduction of the nitrogen-containing anions in particular given their significant …

EFFECTS OF RED BLOOD CELLS ON NITRIC OXIDE BIOACTIVITY
… to 70 folds. Under hypoxic and acidic condition, nitrite is reduced to NO by deoxygenated hemoglobin. Since two states of Hb (R-state and T-state) are reversible under proper condition, Hb acts as an allosterically controlled nitrite reductase. Using electron paramagnetic resonance spectroscopy, …

Molecular assembly and function of Androglobin, a novel chimeric globin.
… that Adgb may have a specialised function in nitrite reduction that could be related to spermatogenesis. The ligation of the full Adgb gene into the pET28a vector and truncation of the full gene was accomplished by molecular cloning techniques something that has not been previously achieved …

Microbiology of the sulfur-dominated glacial ecosystem at Borup Fiord Pass, and high Arctic low-temperature spring associated microbial mats, The
… the potential for sulfur oxidation, nitrate/nitrite reduction, and carbon fixation via the reductive acetyl-CoA and reverse TCA cycles. Also found were genes that allow microorganisms to adapt to adverse conditions in extreme environments. High Arctic microbial communities help to guide our …

Performance and metagenomic microbial analysis of a novel, pilot-scale reactor with rotating algal contactors used to treat anaerobic digester sludge filtrate containing high total ammonia
… removed during treatment, >95% was oxidized to nitrite with 27-36% subsequently evolved as N2 and only 3-11% oxidized to nitrate. The low extent of nitrate formation makes biological nutrient removal less costly, since nitrite reduction demands less oxygen, by 25%, and organic carbon, by 40%, …

Understanding Liquid-Air Interface Corrosion of Steel in Simplified Liquid Nuclear Waste Solutions
… alkaline pHs and concentrations of nitrate and nitrite ions. In addition, linear polarization resistance and electrochemical impedance spectroscopy measurements at OCP in the meniscus and bulk solution could not confirm the hypothesis that the meniscus solution would become increasingly …

Nitrogen cycling in oxygen deficient zones : insights from [delta]¹⁵N and [delta]¹⁸O of nitrite and nitrate
… stable isotopes, [delta]¹⁵N and [delta]¹⁸O, of nitrite and nitrate can be powerful tools used to interpret nitrogen cycling in the ocean. They are particularly useful in regions of the ocean where there are multiple sources and sinks of nitrogenous nutrients, which concentration profiles alone …

Normoxic and anoxic metabolism of Nicotiana tabacum transformants lacking root nitrate reductase
… work was to find out whether and how nitrate reduction in roots would facilitate survival of hypoxic and anoxic (flooding)-phases. For that purpose, we compared the response of roots of hydroponically grown tobacco wildtype (Nicotiana tabacum cv. Gatersleben) and of a transformant (LNR-H) with …
