A T least as early as 1927, copper oxide rectifiers were being tried as ·L modulators for the speech channels of carrier telephone systems In this country.
This talk will present an introduction to the new superconducting materials and some of their potential applications.
Almost all metals and alloys corrode in use. The limits to their use are therefore provided not by the tendency to corrode but by the rates at which the corrosion occurs.
The esthetically pleasing and protective green patina which forms on copper when it is exposed to the atmosphere is complex and has been poorly characterized.
The complex chemical makeup of patinas formed on copper exposed to the atmosphere is summarized, as is the chemical content of atmospheric gases, particles, and water droplets.
Auger electron spectroscopy in conjunction with Ar sup + sputtering has been used to investigate four samples of copper that have been patinated by exposure to the atmosphere for periods ranging f
Each copy of a rest document can be made different in a nearly invisible may by repositioning or modifying the appearance of different elements of text, i.e., lines, words, or characters.
Named Data Networking (NDN) uses content names as routing entries, and thus the scalability of NDN routing is of primary concern.
Over the last two decades, the Internet has moved out of the confines of academic research labs and become a critical infrastructure that is central to nearly every facet of business and the life o
Small tin clusters supported on amorphous carbon substrates were studied by x-ray photoelectron spectroscopy for comparison with earlier work on noble and transition metals in order to assess the r
