  • Silicon Carbide (SiC) and its polytypes have been a part of human civilization for a long time; the technical interest of this hard and stable compound has been realized in 1885 and 1892 by Cowless and Acheson for grinding and cutting purpose, leading to its manufacture on a large scale. The fundamental physical limitations of Si operation at higher temperature and power are the strongest motivations for switching to wide bandgap (WBG) semiconductors such as SiC for these applications.

  • The maintenance of road pavements in England has become a costly necessity, due largely to the large volume of commercial vehicles using the roads which cause pavements to deteriorate quickly, and makes their repair more difficult to carry out. These roadworks incur not only direct works costs, but also indirect costs from factors such as congestion, motor accidents and pollution. There is obviously a need for cost-effective maintenance that minimises the occurrence and duration of these disruptions.
