One of the issues that environmentalists feel most strongly about is recycling. In many communities there is an almost religious fervor surrounding recycling. Unfortunately, there also appears to be widespread misunderstanding regarding th...

The objective of this project was to develop a new approach to 3-D metamaterials. A key step was developing materials with large optical activity. A unique combination of "bottom up" and "top down" approaches to produce nanostructures was successfully applied. Multiscale modeling was used to design chiral polymers. A series of chiral polymers, based on thiophene, fluorene, and fluorene-quinoxal...

Background: Given the popularity of pterional craniotomy, numerous modifications have been made to prevent postoperative deformities. With advent titanium plates, fixation has become both simple and excellent. However, plates can cause skin problems, infection, or skull growth fail. Methods: To develop a simple, cost-effective, esthetically satisfactory method, without use non-metallic material...
