Cryogenics provides the means for obtaining liquid nitrogen and liquid helium for low temperature research, cold traps, etc.
A 230-liter supply of liquid nitrogen is maintained at this facility. Researchers can transfer LN2 to their own dewars (typically 1-30 L) as needed and are billed on a per-liter basis.
LHe orders are delivered to UNL only once a week (Tuesdays), and orders must be submitted to the specialist by the previous Thursday to ensure that the request is placed in time. A delivery location (building and room#) should be specified. LHe can be ordered in 60- or 100-liter containers.
Emergency deliveries of LHe (available with ~ 2 days' notice) are available, but are subject to a special freight charge. (This charge is about $150 - $200.)
Agencies including NSF and the University providing partial support of our Nebraska Nanoscale Facilities and NCMN Facilities require that the following words be included at the end of any Acknowledgement section of a paper in which experimental work was done in NNF-NCMN facilities:
The research was performed in part in the Nebraska Nanoscale Facility: National Nanotechnology Coordinated Infrastructure and the Nebraska Center for Materials and Nanoscience, which are supported by the National Science Foundation under Award ECCS: 1542182, and the Nebraska Research Initiative.
