TECHNOLOGIES OF APPLIED CHEMISTRY B
Learning outcomes of the course unit
The aim of the course is the study of engineering non metallic materials such as polymeric materials, reinforced plastics composite materials and engineering ceramics used in technology. Moreover it deals with several phenomena involved in thermochemical processes aimed at energy production and the main treatments of industrial processes water.
