The holiday season brings two questions: "Isn't it time to put up the Christmas lights?" and "When do we take down the Christmas lights?" Edward Nauman designed retractable icicle lights that go up or down with a flick of a switch. He used rotating lengths of metal conduit to wrap up lights and keep them out of sight behind a facia board. Ed's invention brought peace to his holiday season. The design involves a bracket, a motor, micro-switches, conduit and a few other odds and ends, plus some metalworking experience.
A new method of modeling how they are created with chemical vapor deposition (CVD) could reduce the cost of carbon nanostructures used for for research and commercial applications, including advanced sensors and batteries.
Researchers have been developing a number of nano- and micro-scale technologies that can be used for implantable medical technology for the treatment of disease, diagnostics, prevention, and other health-related applications.
