DeltatiIn 2011 the University of Milano-Bicocca and ERG SpA gave birth to DeltaTi Research, a consortium entirely funded by ERG and aimed at the development of nanostructured silicon-based thermoelectric generators.

Although thermoelectricity is known since 1821, thermoelectric conversion of heat into electric energy has found limited industrial exploitations because of the relatively low conversion yield it enables and of the high material costs.

In spite of the technological limitations, recovering low-enthalpy heat would disclose unpaired opportunities to generate electric power out of thermal waste available both at civil and industrial facilities – further to improve the efficiency of thermal engines.

Based upon a new technological approach developed at the Department of Materials Science and protected by seven international patents, silicon nanostructures might be considered for industrial-scale production of low-cost, high-efficiency generators that will be used both for bulk electric generation and for power microgeneration.

The Consortium R&D activity currently involves, along with the University of Milano-Bicocca as research leader, two CNR institutes, the Universities of Modena, Naples, and Vienna, the Fondazione Bruno Kessler, the Demokritos Research Center, and Altran as a technological consultant.
