Earth Materials Science (EMS) Laboratory


The Earth Material Science Laboratory (EMS Lab) is a research laboratory that focuses on the role of earth materials in 

  • the geochemical cycling and uptake of various elements in the earth’s crust; 
  • how these substances are used as raw materials resources; 
  • and processing of these materials to derive various use and functionality such as in nanotechnology and concrete technology.
