Dubbing the underground pyramids " cavitá " (Italian for ‘hole’ or ‘hollow’), archaeologists have thus far managed to reach about 15 meters (49 feet) down. Much of the site had been intentionally backfilled in ages past for reasons unknown. Clearing the fill material has revealed many artifacts. According to Popular Archaeology, David B. George and colleagues have described the finds; “We know that the site was sealed toward the end of the 5th century BCE. It appears to have been a single event. Of great significance is the number of Etruscan language inscriptions that we have recovered – over a hundred and fifty. We are also finding an interesting array of architectural/decorative terra cotta."
Our research group was the first to synthesize a new family of atomically thin, two-dimensional (2D) transition metal carbides, nitrides, and carbonitrides – called MXenes – via selective etching of the ‘A’ element from MAX phases. We hope to understand the fundamental physics and establish the processing-structure-properties relationships of MXenes. Promising application areas of MXenes include supercapacitor electrodes, transparent conductive coatings, chemical catalysts, EMI shielding and composite reinforcements.
