Mechanism of Selenium Loss in Copper Slag

Metallurgical and Materials Transactions B, 2018
During smelting of copper sulfide concentrate, selenium is distributed between silica-saturated iron-silicate slag and copper-iron sulfide matte. The recovery coefficients of selenium between slag and matte were determined as a function of the initial concentration of selenium at 1523 K (1250 °C) under an inert atmosphere in a vertical tubular furnace.

Copper losses analysis of EV charging couplers

2015 IEEE Magnetics Conference (INTERMAG), 2015
Inductive charging is a promising option for electric vehicle (EV) recharging. It has the advantage of safety, convenience, and durability [1]. The idea of inductive charging is to transfer power to a stopped or moving vehicle across an airgap without physical contact between the vehicle and the grid.

Copper Loss Analysis of EV Charging Coupler

IEEE Transactions on Magnetics, 2015
Electric vehicles numbers are increasing but they still have issues with range between charges. Battery pack energy density is still low compared to the density of fossil fuel so it is advantageous to offer more recharging windows. This will also reduce consumer “range anxiety”.

Copper loss from the copper T model TCu22OC.

Contraception, 1983
The effect of mineral deposits on the copper dissolution rate of the Copper T Model TCu22OC was examined. 118 Copper T22OC devices removed from subjects for various medical and personal reasons after 12 to 72 months in utero were examined and graded based on the proportion of the total copper area covered with mineral deposits.

Suppression of Copper Thin Film Loss during Graphene Synthesis

ACS Applied Materials & Interfaces, 2015
Thin metal films can be used to catalyze the growth of nanomaterials in place of the bulk metal, while greatly reducing the amount of material used. A big drawback of copper thin films (0.5-1.5 μm thick) is that, under high temperature/vacuum synthesis, the mass loss of films severely reduces the process time due to discontinuities in the metal film ...

Astrocytes Protect Against Copper-Catalysed Loss of Extracellular Glutathione

Neurochemical Research, 2008
Glutathione (GSH) is one of the major antioxidants in the brain. GSH is secreted by astrocytes and this extracellular GSH is used by neurones to maintain and increase their intracellular GSH levels. For efficient GSH trafficking between astrocytes and neurones, GSH needs to be maintained in the reduced form.

Iron and copper loss measurement in transformers

Electrical Engineering, 1958
IT IS HIGHLY DESIRABLE to improve the accuracy of measurement of transformer iron and copper losses. Unless accurate measurements are available, it is difficult to evaluate the benefit of modifications in processes and constructions intended to reduce the winding eddy losses, stray losses in the tanks, and the iron loss.

Copper toxicity in Alzheimer's disease: Cognitive loss from ingestion of inorganic copper

Journal of Trace Elements in Medicine and Biology, 2012
In this review I present the hypothesis that a toxic substance, inorganic copper, ingested from drinking water and vitamin/mineral supplements containing inorganic copper, is at least partially causal of the epidemic of Alzheimer's disease (AD) we are seeing in developed countries.

A simple method for optimal control of PMSM with loss minimization including copper loss and iron loss

2017 Twelfth International Conference on Ecological Vehicles and Renewable Energies (EVER), 2017
the goal of this paper is to present a comprehensive method to optimize the dq reference frame current of a permanent magnet synchronous machine (PMSM) including both copper and iron losses. The originality of the article concerns on the one hand the direct consideration of a resistance modeling iron loss in the circuit model and on the other hand the ...

Dielectric Loss Characteristics of Copper-Contaminated Transformer Oils

IEEE Transactions on Power Delivery, 2010
The relationships between the total copper content, both in dissolved and suspended form, and the dielectric loss characteristics were examined in transformer-type oils. It was established that the dielectric losses in the oils are a function of the total copper content.
