Many roofs of asbestos, aluminum, stainless steel, galvanized steel, and lead-coated copper may soon have historic values as well. Awareness of these and other traditions of roofing materials and their detailing will contribute to more sensitive preservation treatments.
“We accidentally discovered that a simple solution is to use graphite, which is basically carbon. In our study, we identified a few types of graphite material that give us very good performance.” For the experimental battery, the Stanford team placed the aluminum anode and graphite hode, along with an ionic liquid electrolyte, inside a flexible polymer-coated pouch.

When we look at these types of physical properties, the limit of elongation is between 1.9 and 3.9% for cellulose, with a tensile strength between 4.9 and 6.4 gram weight per denier. In contrast, the limit elongation ratio of silk is 7 times as high at 20 to 23% while, conversely, the tensile strength is weaker at 3.6 to 4.1 gram weight per denier.
