... replacement of the original copper roofing on Kingswood School, Cranbrook Educational Community, a National Historic Land-mark in Michigan, serves as a model for this current research. Designed by noted architect Eliel Saarinen and constructed in 1931, the building's extensive copper roof is a character...

... Miniature tensile specimens of high purity iron and iron-copper alloys containing 0.1 and 0.3 weight percent copper were irradiated at 150°C and 290°C in the HFIR to 0.025 and 0.1 dpa. Following irradiation, room temperature tensile tests were performed. The effect of copper content on the yield...

..., thus considering a broad spectrum of climatological and pollution conditions. This work compares, for the four reference materials (carbon steel, zinc, copper and aluminium), the corrosion data obtained in the ISOCORRAG and MICAT programmes, as a function of the environmental variables of the different...

... A major on-going research project is described that aims at generating relevant data for future risk assessments of environmental effects caused by copper, zinc, chromium and nickel release from roof materials. Cross-disciplinary activities have been implemented that range from the metal release...

... Runoff rates of copper have been determined during a one-year field exposure in the city of Singapore, Republic of Singapore, and a four-year exposure in the city of Stockholm, Sweden, from brown and green pre-patinated copper sheet and naturally patinated copper sheet being fresh and 130 years...

... Precipitation runoff experiments were conducted on copper panels at sites polluted with sulfur dioxide (Washington, DC), an unpolluted site (Albany, OR), and an unpolluted marine site (Newport, OR). Copper patinas had complex surface chemistry representing a sequence of transitional mineral...
