Copper losses in power integrated inductors on silicon
Conference Record of the 2002 IEEE Industry Applications Conference. 37th IAS Annual Meeting (Cat. No.02CH37344), 2003One of the major goals in power electronics is the integration of the passive and active part of converters, on the same piece of silicon. In this context, our laboratory works on magnetic components integration. To have the right dimensioning of these components, we firstly have to choose the best topology regarding losses. The aim of this paper is to

Ultralow-loss CMOS copper plasmonic platform
2017 Conference on Lasers and Electro-Optics Europe & European Quantum Electronics Conference (CLEO/Europe-EQEC), 2017The 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 ...

Urinary zinc, copper, nitrogen, and potassium losses in response to trauma
Journal of Parenteral and Enteral Nutrition, 1979The urinary losses of zinc, copper, nitrogen and potassium were measured for 14 trauma patients for periods ranging from nine to 30 days and for nine normal subjects over four days each. The mean losses per day as well as peak losses by patients were compared to the mean normal losses.

Copper clustering and vacancy loss during the quenching of aluminium-copper alloys
Acta Metallurgica, 1966Abstract The time taken to quench specimens of aluminium-copper alloys in wire form and their subsequent ageing rates have been determined using electrical resistance measurements. It was found that the quenching speed was proportional to the square of specimen radius and that the observed quenching times were the sum of the time taken to cross the ...

Modeling and control of copper loss in smelting slag
JOM, 2011A series of technical improvements have been implemented to address the issue of high copper losses in rotary holding furnace (RHF) slag, which were experienced at the Xstrata Copper Smelter at Mount Isa in 2007 and 2008. The copper losses in smelting slag in the RHF were more than 3% in 2006 and 2007.

Loss of therapeutic copper in closed marine systems
Aquaculture, 1981Abstract The disappearance of therapeutic copper from solution in closed marine culture systems was investigated using a spectrophotometric assay. When copper sulfate or a copper sulfate-citric acid mixture was added to marine aquariums containing various calcareous filtrants, activated carbon, silica gravel, or cured coral, a relatively rapid ...
