The consultants hope to begin this phase of the project as early as Tuesday , April 10 , 2001 . The projects are well-defined in scope and they address a variety of supply chain management problems . The projects are supported by partner companies , who provide a challenging problem for the students to work on . Changes in the opponents do not require changes in the program . They first grow patterns of carbon nanotubes on silicon surfaces using chemical vapor deposition , and then the nanotubes are transferred to metal surfaces that are coated with solder - - a metal alloy that is melted to join metallic surfaces together .
