Applicable Classes

Name	Description	Modifies Slot
Reagent	A ChemicalSubstance that is consumed or transformed in a ChemicalReaction.	no
Precursor	A MaterialSample that serves as input material in a catalyst Synthesis. Precursors are consumed or transformed during the preparation process.	no
Microreactor	Microreactor — a miniaturised flow reactor with characteristic dimensions in the sub-millimetre range, enabling precise thermal control and rapid screening.	no
PlugFlowReactor	Plug flow reactor (PFR) — a tubular reactor in which reactant composition varies along the axis with no axial mixing.	no
FluidizedBedReactor	Fluidized bed reactor — a reactor in which the catalyst particles are suspended in an upward-flowing gas or liquid stream.	no
Microkinetics	Microkinetic modelling — a mean-field kinetic approach that integrates elementary reaction steps and their rate constants to predict catalytic activity and selectivity under reaction conditions.	no
MaterialisticMixin	A LinkML mixin used to pass down properties common to all material entities. It is needed for example to have MaterialSample have the same properties as MaterialEntity, although it is defined as a subclass of EvaluatedEntity.	no
PolymerMixin	A LinkML mixin used to pass down properties common to all chemical substances that are composed of macromolecules of different kinds and which may be differentiated by composition, length, degree of branching etc..	no
ChemicalSubstanceMixin	A LinkML mixin used to pass down properties common to all material entities that are described in a chemical context via being composed of chemical entities (e.g. atom, molecule, ion, ion pair, radical, complex, conformer etc., ) of the same type or of different types.	no
SlurryReactor	Slurry reactor — a three-phase reactor in which catalyst particles are suspended in a liquid phase through which gas is bubbled.	no
CSTR	Continuous stirred tank reactor (CSTR) — a well-mixed, continuous-flow reactor operating at steady state.	no
MaterialSample	A Sample that was derived from a previous MaterialSample or some other kind of MaterialEntity.	no
DissolvingSubstance	A liquid ChemicalSubstance that dissolves or that is capable of dissolving a ChemicalSubstance.	no
FixedBedReactor	Fixed bed reactor — a tubular reactor packed with a stationary catalyst bed. The most common reactor type in heterogeneous catalysis testing.	no
SubstanceSample	A MaterialSample derived from a chemical substance that is of interest in an analytical procedure.	no
CatalystSample	A MaterialSample that is the product of a catalyst Synthesis. The specific type of catalyst (e.g. heterogeneous, supported metal) is expressed via rdf_type using a VOC4CAT term.	no
CatalyticReaction	A ChemicalReaction (chemdcat-ap) specialization representing the catalytic reaction being studied. Inherits the generic reaction slots (starting materials, reactants, products, catalyst, solvent, reactor, temperature, pressure, yield, reaction steps) from ChemicalReaction and adds catalysis-specific operating-condition slots. Reaction is NOT a DataGeneratingActivity — it is the catalytic process being observed, not the process that generates the dataset. A CatalysisDataset is linked to the Reaction it is about via is_about_activity. For operando experiments (e.g. in-situ XRD during a reaction), the dataset carries both: was_generated_by: Characterization (the measurement producing data) is_about_activity: Reaction (the catalytic process being monitored) The reactor is linked via the inherited used_reactor slot (is_a: carried_out_by), narrowed here to require a ChemicalReactor instance rather than touching the generic carried_out_by relation directly. Reactants are linked via the inherited used_reactant slot (range: Reagent) -- CatalyticReaction does not declare its own reactant slot. The type of catalytic reaction (e.g. ammonia synthesis, CO oxidation) is expressed via rdf_type using a voc4cat or ChemO term.	no
Autoclave	Autoclave reactor — a sealed pressure vessel for batch reactions at elevated temperature and/or pressure.	no
Catalyst	A ChemicalSubstance or MaterialEntity that initiates or accelerates a ChemicalReaction without itself being affected.	no
ChemicalReaction	A process that leads to the transformation of one set of chemical substances to another and that is the subject matter of a DataGeneratingActivity.	yes
Reactor	A reactor is a container for controlling a biological or chemical reaction or process.	no
MaterialEntity	A material is an Entity that has some portion of matter as proper part.	no
PolymerSample	A SubstanceSample derived from a Polymer.	no
ElectrochemicalReactor	Electrochemical reactor used in electrocatalytic experiments, including H-cells, flow cells, and membrane electrode assemblies.	no
ChemicalReactor	Abstract Reactor (chemdcat-ap) subclass representing a catalytic reactor vessel. Reactor is more specific than the general Device (AgenticEntity): it restricts the used_reactor relation (is_a: carried_out_by) on Reaction to dedicated reactor equipment. This semantic distinction separates analytical instruments (Device) from reaction vessels (Reactor). ChemicalReactor further specializes chemdcat-ap's generic Reactor for catalysis use cases. Concrete subclasses (FixedBedReactor, CSTR, PlugFlowReactor, …) specify reactor geometry and operating mode. Linked from Reaction via used_reactor (restricted to range: ChemicalReactor).	no
StartingMaterial	A ChemicalSubstance with that has a starting material role in a synthesis.	no
ChemicalProduct	A chemical substance that is produced by a ChemicalReaction.	no
