All BNC Users - The preventive maintenance shutdown of the Birck Nanotechnology Facility has been completed successfully due to the efforts the Engineering Staff and the Zone 7 Physical Facilities trades. The cleanroom and laboratories are now open for operation. Some equipment is still shut down for maintenance, or is in the process of being started back up. Please check Coral for individual equipment status. Thank you for your patience and understanding during this set of important preventive-maintenance procedures.
