Copper loss from the Copper T model TCu220C

Contraception, 1982
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.

Energy Loss Spectrum of Copper

Journal of the Physical Society of Japan, 1976
The complex dielectric function e (0,ω) of copper is calculated by a realistic band model up to \(\hbar\omega{=}25\) eV. the energy values ad the wave functions are calculated by APW method with the Chodorow potential. The eleven energy bands are used to obtain the matrix elements of the interband transitions.

Cutaneous copper and zinc losses in burns

Burns, 1992
To measure the exudative cutaneous copper (Cu) and zinc (Zn) losses in burns, 10 patients, aged 36 +/- 9 years (mean +/- s.d.) with burns covering 33 +/- 10 per cent of the total body surface area, were studied from the first postburn day (D1) until D7. All intakes and losses were analysed for Cu, Zn and nitrogen (N) content.

Menstrual blood loss with copper intrauterine devices

Contraception, 1974
Abstract Menstrual blood loss was estimated quantitatively by Halberg & Nilson method for 336 women: 145 normal controls (240 cycles); 91 fitted with Cu-devices (349 collected cycles); 50 fitted with Lippes loops (224 cycles) and 50 on combined steroid contraceptive therapy (236 cycles).

No-load copper eddy-current losses

Journal of the A.I.E.E., 1926
One of the factors which is sometimes responsible for very considerable losses in rotating machines is that of eddy-current losses in the copper conductors resulting from slot leakage flux produced by the main flux. These losses occur at no-load as well as under load and should not be confused with the copper losses resulting from the slot leakage flux

Loss of copper from oxychlorination catalysts

Journal of Applied Chemistry and Biotechnology, 1973
AbstractDuring the oxychlorination process, there are losses of copper from the catalyst as a result of a reaction with the walls of the reactor: the cupric ions are reduced to metallic copper and deposited on the walls. We have observed rates of deposition of the order of 10−2 g of copper per cm2 of walls per year, for walls of pure iron.

Ultralow-loss CMOS copper plasmonic platform

2017 Conference on Lasers and Electro-Optics Europe & European Quantum Electronics Conference (CLEO/Europe-EQEC), 2017
The size of photonic components is fundamentally limited by the diffraction of light, while miniaturization is one of the key concepts in the development of high-speed and energy-efficient electronic and optoelectronic chips. Plasmonics attracts great interest thanks to the unique opportunity to confine light to a space much smaller than the light ...

Discussion on design optimization of inductor loss focused on copper loss and iron loss

2013 1st International Future Energy Electronics Conference (IFEEC), 2013
High-frequency switching of a power converter enables reduction of the volume of inductors. However, the temperature of the inductors becomes higher, because the thermal resistance of the inductor is increased. Therefore, accurate loss calculation of the inductor is one of the most important concerns for high-power-density converters.

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.
