Electrical Conductivities of Conductors, Semiconductors, and Their Mixtures at Elevated Temperatures
Advanced Engineering Materials, EarlyView.This article presents a comprehensive review of temperature‐dependent electrical conductivity data for multiple material classes at elevated temperatures, highlighting a persistent conductivity gap between metals and semiconductors in the range of 102$\left(10\right)^{2}$– 107$\left(10\right)^{7}$ S/m. Metal–ceramic irregular metamaterials are proposed

Effect of dissolved oxygen and aeration management on nitrification in catfish ponds
Journal of the World Aquaculture SocietyDissolved oxygen management of ponds plays a critical role in ictalurid catfish aquaculture production. If the minimum dissolved oxygen concentration falls below 3.0 mg O2 L−1, appetite is reduced, and production ultimately decreases. Although the effect

Chemiluminescence from Dissolved Oxygen [PDF]
Nature, 1964 RED chemiluminescence corresponding to about 40 kcal/mol., and attributable to the forbidden transition 1Σ+g → 3Σ−g of the oxygen molecule, has been observed in three recent investigations1–3, but no explanation of the effect has been presented. These involve organic hydroperoxides or oxidations with hydrogenperoxide and also the reaction of hydrogen ...

Relationships between secchi disk visibility, water temperature and dissolved oxygen in freshwater fishpond [PDF]
, 2007 A study was conducted to determine the relationships between secchi disk variability, water temperature and dissolved oxygen in fish ponds. Multiple regression correlation analysis was done to evaluate the relationships between the variables.

Advanced Engineering Materials, EarlyView.Carbon‐free inert anodes are essential for decarbonizing aluminum electrolysis. This study investigates a recyclate‐based MgO‐316L steel composite anode tested under galvanostatic Hall–Héroult conditions in cryolite at 1000°C. Microstructural analysis reveals selective MgO fluorination, spinel and oxide layer formation, electrolyte infiltration, and ...

A survey of the marine environment near the city of Seaside ocean outfall [PDF]
, 1973 Department biologists, under contract for the State Water Resources Control Board, conducted a survey of the marine environment in the vicinity of the City of Seaside ocean outfall. Survey procedures included benthic grabs, diver observations, bottom

Advanced Engineering Materials, EarlyView.The formation of nonmetallic inclusions (NMIs) was investigated in this study, carrying out immersion tests for 30 min at a temperature of 1600°C with liquid high‐silicon electrical steel (Si ≈ 3 mass‐%) and different MgO–C refractories. Conventional MgO–C refractories were considered, as well as MgO–C refractories containing MgO–C recyclate and ...
