Copper nanowires and silver micropit arrays from the electrochemical treatment of a directionally solidified silver–copper eutectic
The method of fabricating metallic nanowires from directionally solidified eutectics was applied to the silver–copper system. The silver–copper lloy, 39.9 at.% copper, was directionally solidified in a Bridgman-type oven held at 850 ◦C. SEM imaging revealed a mixed fibrous and lamellar icrostructure. The fastest solidification rates produced fibres and lamellae with widths as small as 300 nm. E...
متن کاملCoping with Resistance to Copper / Silver Disinfection
www.waterinfocenter.com The biocidal effects of copper and silver have been used for centuries. The early Greeks and Romans made water storage and drinking vessels out of these metals, and enough dissolved in the water stored in them to produce substantial disinfection. More recently, copper and silver ions have been used in hospital, recreational, drinking and industrial water systems. Unlike ...
متن کاملGraphene-protected copper and silver plasmonics
Plasmonics has established itself as a branch of physics which promises to revolutionize data processing, improve photovoltaics, and increase sensitivity of bio-detection. A widespread use of plasmonic devices is notably hindered by high losses and the absence of stable and inexpensive metal films suitable for plasmonic applications. To this end, there has been a continuous search for alternati...
متن کاملHospital-acquired legionnaires disease in a university hospital: impact of the copper-silver ionization system.
We evaluated the impact of the copper-silver ionization system in a hospital where hyperendemic nosocomial legionellosis and was present and all previous disinfection measures had failed. After implementation of the copper-silver ionization system, environmental colonization with Legionella species decreased significantly, and the incidence of nosocomial legionellosis decreased dramatically, fr...
متن کاملMagnetic trapping of silver and copper, and anomalous spin relaxation in the ag-he system.
We have trapped large numbers of copper (Cu) and silver (Ag) atoms using buffer-gas cooling. Up to 3 x 10{12} Cu atoms and 4 x 10{13} Ag atoms are trapped. Lifetimes are as long as 5 s, limited by collisions with the buffer gas. Ratios of elastic to inelastic collision rates with He are >or=10{6}, suggesting Cu and Ag are favorable for use in ultracold applications. The temperature dependence o...
