Argonne National Laboratory, including the Center for Nanoscale Materials (CNM), will be closed beginning December 23, 2019, and will reopen on January 2, 2020. Neither the CNM building nor CNM staff, including administrative support, will be available to users during the winter break.
 
The winter break will be followed by a preventive maintenance period, from January 6 to January 12, 2020. During this period some capabilities may be unavailable at times and the servicing of some infrastructure systems may affect operations. More information will be sent as the date nears.
