Scientific terms
Public service announcement: I'm not a physicist.
- PLD deposition: fabrication method.
- Sample: what is being produced by a deposition. A sample is made up of different stacked layers of material (target) deposited upon another material (substrate).
- Target: material "consumed" during the deposition.
- Substrate: material on which the target is deposited.
- Compound: which material is a target or a substrate made of; substrates of the same batch are made of the same compound.
- Layer: one of the layers of material of which a sample is composed; every layer can have different properties, both in the physical sense (i.e. shape, thickness...) and regarding their manufacturing process (i.e. frequency of pulses, deposition temperature and pressure...).
eLabFTW glossary
PSA: I'm not a Deltablot developer either.
- Experiment: main type of entry on eLabFTW, used to store data related to the single experiment.
- Resource or Item: secondary type of entry on eLabFTW, used to store data related to resources such as raw materials, instruments, machinery etc.
- Elabid: unique ID used to identify a resource or an experiment; resources and experiments have different indexing and different API endpoints.
- Categories: experiments or resources with common characteristics are associated by assigning them to the same category - e.g. experiments flagged as "PLD Deposition" contain data on a layer of a sample; categories also come with a mask of parameters (extra fields) which need to be compiled by the user.
- Metadata: extra data; in eLabFTW it all falls under either the key "metadata" (as a single string of text) or the key "metadata_decoded". Metadata is then divided into "extra_fields" and "extra_fields_groups" - of which usually only the first one contains relevant metadata.
- ReST API: something I use to get my JSON files; endpoints are the URLs I point my requests to.
- JSON: fancy dictionaries with important data.

What is what
At CNR-SPIN @Na we use eLabFTW resources to store:
- Our samples;
- Our instruments;
- Our substrate batches and our PLD targets;
- The compounds substrates and targets are made of (incl. chemical formula);
- Other things.
We use experiments to store:
- Our laboratory journals;
- The layers a sample is made up of.
