How to use the CRC/TRR 247 Database?

Three different types of entries can be created: Samples, Experiments and Documents. In all cases, there are mandatory fields that need to be filled as well as optional ones that may contain additional (internal) information. An additional important tool is to create and use tags for each entry, which allows to search our database in an efficient manner. Please choose, if possible, from the list of existing tags before creating new ones. For all three types of entries, attachments can be uploaded.

  1. Samples: Once you synthesize a sample, an entry must be created before the sample is submitted to any experiment. From the entered data, the database software will create a unique sample name starting with the letter. It is mandatory to use this name in any internal and official communication of the CRC/TRR 247. If the sample is further treated, e.g. calcined at different temperatures, each product is a new sample and requires a new database entry. In this case, you should use the “parent-child” connection for the sample ancestry. Attachments to be uploaded should be limited to data clearly referring to the synthesis experiment itself, hence no characterization data should be uploaded here.
  2. Experiments: An experiment can be linked to one sample and the upload should contain the raw data. If you perform the same experiment on more than one sample, a new experiment entry should be created for each of the measurements. The experiments will be named automatically, starting with the letter E.
  3. Documents: Documents are any experimental reports containing evaluation of the raw data, but also presentations, posters or publications for internal and external use. These should be linked to the experiment entries that have been evaluated and are described or interpreted in the documents. While the database allows tracking the sample names via the linked experiments, the documents themselves should nevertheless contain and use the sample labels from the database, e.g. in tables and on slides. In publications, the assignment of samples to the database names can be done as supporting information, if the labels are not used in the main text.
