Work and Power: Waterwheel
Investigating a waterwheel illustrates to students the physical properties of energy. They learn that the concept of work, force acting over a distance, differs from power, which is defined as force acting over a distance over some period of time. Students create a model waterwheel and use it to calculate the amount of power produced and work done.
A Metadata Based Web Distance Learning Platform
Distance Learning is acquiring a role that becomes more and more important with the huge diffusion of the Internet and related technologies. Consequently, the investigation for adequate architectures and platforms supporting flexible Distance Le arning engines and solution is nowadays of great interests in the Scientific Community. The present paper introduces a platform based on the adoption of Metadata concepts and on the use of a “processorlike” behavior of the Web Course Delivery engine
In this activity, students learn how engineers use solar energy to heat buildings by investigating the thermal storage properties of some common materials: sand, salt, water and shredded paper. Students then evaluate the usefulness of each material as a thermal storage material to be used as the thermal mass in a passive solar building.

Novel organic-inorganic hybrid mesoporous materials and nanocomposites
Organic-inorganic hybrid mesoporous materials have been prepared successfully via the nonsurfactant templated sol-gel pathway using dibenzoyl-L-tartaric acid (DBTA) as the templating compound. Styrene and methyl methacrylate polymers have been incorporated into the mesoporous silica matrix on the molecular level. The synthetic conditions have been systematically studied and optimized. Titania based mesoporous materials have also been made using nonionic polyethylene glycol surfactant as the pore
