A recent study concludes that the coins release up to 320 times as much nickel as European standards permit for prolonged contact with the metal - a common skin allergen. The culprit is the anodic action between the coin's double nickel alloy construction. A 40 mA current flows between the two alloys at the interface. "It's like a mini-battery," said one investigator. The current leads to corrosion and the release of nickel ions. Job Announcement: The E.U. is in desperate need of a junior level college chemistry major to consult before settling on the design of the new euro coins. |

RF Cafe began life in 1996 as "RF Tools" in an AOL screen name web space totaling 2 MB. Its primary purpose was to provide me with ready access to commonly needed formulas and reference material while performing my work as an RF system and circuit design engineer. The World Wide Web (Internet) was largely an unknown entity at the time and bandwidth was a scarce commodity. Dial-up modems blazed along at 14.4 kbps while typing up your telephone line, and a nice lady's voice announced "You've Got Mail" when a new message arrived... All trademarks, copyrights, patents, and other rights of ownership to images and text used on the RF Cafe website are hereby acknowledged. My Hobby Website: AirplanesAndRockets.com
