We’ve just updated the NCDS to the all-new DETHERM website – try it out now
With 8.9 million data sets relating to 44,200 pure compounds and 139,400 mixtures, DETHERM is an invaluable resource for researchers in chemistry and related fields. This update features a much-improved search system and user interface, making it easier for you to search the DETHERM database of thermophysical properties.
Thermophysical data from 2013 has now been added to the DETHERM database. New data added from 2013 includes:
DETHERM now contains data from over 100,000 literature documents, equating to over 8,000,000 data rows:
