Everyone, Our custodial staff will be stripping and re-waxing the floors again this summer. Please be aware that some of the hallways will be blocked off. If you are using the labs, please enter and exit from the galley doors. All waxing will be done between 5:00AM to 9:00AM. Please let me know if you have any questions. Thank you, Mary Jo Totten Birck Nanotechnology Center Discovery Park/Purdue University 1205 West State Street West Lafayette, IN 47907-2057 (765) 496-1173
