Roland Piquepaille writes: "An international team of scientists from Chile, the Netherlands and the U.S. has found a very simple way to measure the material properties of thin films having a thickness of only a dozen nanometers. The researchers just dropped water on thin film floating in a Petri dish. This causes wrinkles to appear on the ultrathin polymer films they've tested. And they found that the number and length of the wrinkles are determined by the elasticity and thickness of the film. In other words, they've found an easy way to discover the mechanical properties of films which might be used for applications such as cosmetics, coatings, and nanoelectronics. Read more for additional references and pictures of wrinkles in nanotechnology-based films."

In this tip, you learn to use the XML Schema Standard Type Library to simplify the process of requiring formatted data such as e-mail addresses and telephone numbers.

No specific reasons were pinpointed in the announcement other than the software was not meeting its quality checkpoints in June and July of this year. Surprise, surprise."
