Every night a massive migration takes place in ocean waters. Zooplankton and micronekton, a diverse group of organisms <1 mm to 10 cm in size, swim up from midwater depths (200–700 m) to the surface ocean to feed and return down to resting depths before daybreak. The importance of this diel vertical migration to marine biogeochemical cycles has been recognized for some time. Research has primar...

In many oceanic regions, growth of phytoplankton is nitrogen-limited because fixation of N2 cannot make up for the removal of fixed inorganic nitrogen (NH4+, NO2-, and NO3-) by anaerobic microbial processes. Globally, 30-50% of the total nitrogen loss occurs in oxygen-minimum zones (OMZs) and is commonly attributed to denitrification (reduction of nitrate to N2 by heterotrophic bacteria). Here,...

Past work in this laboratory has shown that nuclear particles generated during electrolysis can be registered by CR39 plastic detectors held within the electrolyte solution, suspended in the vapor above the solution, or placed just below the metal cathode that serves as the bottom of the electrolyte compartment of the electrolysis cell. However, not every electrolysis experiment produced nuclea...

Nuclear energy can be used as the primary energy source in centralized hydrogen production through high-temperature thermochemical processes, water electrolysis, or high-temperature steam electrolysis. Energy efficiency is important in providing hydrogen economically and in a climate friendly manner. High operating temperatures are needed for more efficient thermochemical and electrochemical hy...

We performed a ultra—short width high voltage pulse electrolysis using a thin Pd wire cathode; a diluted electrolytic solution of D2O+LiOD was used in a peculiar wire—turned electrodes geometry. The deuterated Pd loading was evaluated by the D/Pd normalised electric resistance curve (R/Ro). After a long time of electrolysis a very high D/Pd loading (1:1 or more) was reached. Very low R/Ro (< 0....

Ovomucoid (OMC) is the most prominent allergen causing hen's egg allergy, containing disulfide (S-S) bonds that may be responsible for its allergic action. As S-S bonds may be reduced during electrolysis, this study was undertaken to evaluate modulation of the allergic action of OMC after electrolysis. Electrolysis was carried out for 1% OMC containing 1% sodium chloride for 30 minutes with a v...

A low cost Medium Intensity Upgrade has been proposed for ATLAS facility to accelerate ion beams with intensities 10-15 higher than beams currently available. This encompasses upgrades and replacements in some of the existing equipment. This project mainly attempts to simulate and optimize the design of RF Cavities and RFQ for the proposed upgrade. For RF Cavities, we aimed at simulating super ...

To be regarded as environmentally friendly and economical, an industrial process using 2,2,6,6-tetramethylpiperidine 1-oxyl (TEMPO) oxidation requires recycling and/or recovery of chemicals. In this work, hypochlorite recycling via electrolysis was evaluated and potential means for TEMPO recovery were explored. The most important variable affecting electrochemical hypochlorite conversion was th...

Partial-nitritation anammox (PNA) is a novel wastewater treatment procedure for energy-efficient ammonium removal. Here we use genome-resolved metagenomics to build a genome-based ecological model of the microbial community in a full-scale PNA reactor. Sludge from the bioreactor examined here is used to seed reactors in wastewater treatment plants around the world; however, the role of most of ...
