Open a family to keep every result attached to its sample, method and conditions.
Paraphrased for this database from the authors’ stated interpretations — never quoted verbatim — and kept separate from reported measurements.
The paper reports enzyme-in-ZIF synthesis, structure, porosity, fluorescence and catalytic activity, but no electrical conductivity, thermoelectric or electrochemical transport data.
Caveat: The assigned category is core_transport_physics, but the source article itself is an enzyme immobilisation/catalysis study.
1 · Abstract
The retained activity of CAT@ZIF-90 in urea is not attributed merely to slow urea diffusion because urea reaches equilibrium in ZIF-90 after about 20 min.
Caveat: Urea amount data in Figure 2b are graphical; the equilibrium time is explicitly stated in the main text.
2 · Diffusion control · Figure 2b · Linked to 4 structured results
Embedding catalase in ZIF microcrystals via the de novo approach preserves catalytic function under urea and heat denaturation by limiting structural changes.
Caveat: The study is enzymatic catalysis and spectroscopy, not electronic/electrical transport.
4 · Summary · Linked to 4 structured results
ZIF confinement does not protect catalase from the active-site inhibitor 3-AT, supporting the interpretation that the MOF mainly reduces unfolding rather than blocking all guest access.
Caveat: This is a mechanistic control for enzyme inhibition rather than a framework electrical-transport measurement.
