Does conductivity increase or decrease with dissolved oxygen?
5 answers
Conductivity tends to increase with dissolved oxygen levels. Research indicates that in the presence of higher dissolved oxygen concentrations, such as 9 mg L−1, the conductivity of water increases due to the formation of dissolved ozone and hydrogen peroxide, leading to higher conductivity levels. Additionally, a study on the effect of dissolved oxygen on the oxidation reaction of anodes in microbial fuel cells found that the current output decreased by 7% with the impact of dissolved oxygen, suggesting a correlation between dissolved oxygen and conductivity changes. Furthermore, the corrosion behavior of X80 pipeline steel in simulated soil solutions showed that as the dissolved oxygen concentration decreased, the corrosion current density reduced significantly, indicating a decrease in conductivity with lower dissolved oxygen levels.
What are the desadventages of direct recycling for lithium ion batteries?
4 answers
Direct recycling of lithium-ion batteries (LIBs) presents several disadvantages. Firstly, the inhomogeneity of harvested materials due to variable experiences during use can impact the consistency of recycled materials. Secondly, traditional methods like salt-water discharge for safe disassembly can lead to internal contamination and electrode corrosion. Additionally, while direct recycling is energy-efficient, challenges such as efficient separation, binder removal, and electrolyte recovery hinder its widespread adoption. Despite its promise in recovering valuable metals without extensive processing, direct recycling still faces technological hurdles that need to be addressed for industrial application.
What are the desadventages of hydrometallurgical process Libs recycling?
4 answers
The hydrometallurgical recycling method for Lithium-ion batteries (LIBs) presents some disadvantages despite its advantages. One major drawback is the relatively complicated process involved in hydrometallurgical recycling, which can increase operational complexity and costs. Additionally, this method generates more wastewater compared to other recycling techniques, posing environmental concerns and requiring proper wastewater management. Impurities introduced during the recycling process, such as cations, anions, and neutral insoluble substances, can impact the quality of the recovered materials, affecting cathode properties like morphology and powder density. Furthermore, inorganic acids used in the leaching process lack selectivity for valuable metals, leading to the simultaneous leaching of metallic impurities into the solution, complicating subsequent purification steps.
What is the thermal conductivity of wax at liquid state?
4 answers
The thermal conductivity of wax in the liquid state varies depending on the composition and additives. Studies have shown that the addition of carbon nanotubes (CNTs) to paraffin wax (PW) can lead to a significant enhancement in thermal conductivity. Conversely, the thermal conductivity of PW doped with fullerene C60 showed no significant increase in the liquid phase. Experimental results indicate that pure n-docosane, a type of paraffin, has a thermal conductivity of 0.49 W m−1 K−1 in the solid state. Additionally, measurements on wax in both solid and liquid states have shown a retrograde tendency in conductivity above the melting point, with discrepancies between experimental and predicted values. Therefore, the thermal conductivity of wax in the liquid state can be influenced by various factors, including additives and temperature.
What is the value thermal conductivity of wax at liquid state?
5 answers
The thermal conductivity of wax in the liquid state varies depending on the specific type and composition of the wax. Studies have shown that for paraffin wax, the addition of 10% carbon nanotubes (CNTs) can lead to a thermal conductivity enhancement of around 40.2% in the liquid state. Additionally, research on beeswax has indicated that the thermal conductivity of different types of beeswax is influenced by temperature, with values being higher at extreme temperatures and relatively constant between 0 and 25°C. These findings suggest that the thermal conductivity of wax in the liquid state can be significantly influenced by additives like CNTs and can vary based on the specific wax type and temperature conditions.

Additionally, the presence of metal complex catalysts in epoxidized sucrose soyate curing reactions influences the reaction kinetics, with multiple exothermic peaks indicating various reaction mechanisms. Moreover, the catalytic effect of carbon nanotubes in epoxy curing is attributed to altering the microgel structure, affecting the reaction rate dependencies on structural parameters. Understanding catalyst decomposition mechanisms is crucial for optimizing polymerization processes and enhancing the efficiency of epoxy curing reactions.
What is the density carbon fibre of in terms of high low or medium?
5 answers
The density of carbon fibers can vary depending on the specific type and manufacturing process. High-density carbon fibers are characterized by a fiber density of not less than 1.93 g/cm³, while low-density carbon fibers are designed to have a low density for lightweight structures. Additionally, in the context of fiberboards, high-density fiberboards have a density range of 800-900 kg/m³. These variations in density cater to different applications, with high-density fibers offering strength and modulus advantages, while low-density fibers are favored for reducing weight in composite materials. Therefore, carbon fibers can be classified into high-density, low-density, and medium-density categories based on their specific applications and performance requirements.
