Supporting data: reaction–demixing coupling and Cu(II) uptake at ionisable acidic sites in Jatropha-oil-derived precursor/polyethersulfone membranes
Description
Supporting data for “Reactive aqueous NIPS of a Jatropha-oil-derived precursor with polyethersulfone: reaction–demixing coupling and Cu(II) uptake at ionisable acid sites” (Journal of Membrane Science). Every mean ± SD printed in the article and its Supporting Information is recomputable from these records, as is every p value in Table S87. No vendor-native instrument files or raw images are included. FILES 1. JPUPES_Revision_Dataset.xlsx (32 sheets) — the fourteen measurement series added for the first revision (Notes S18–S31; Tables S78, S81, S88, S89, S91, S96–S104). One RAW_* sheet per acquisition with instrument, method and batch identifiers; a QC_* sheet of hard-gate checks per domain; ANALYSIS_* sheets for derived quantities. 00_README gives the sheet families and the time convention. 2. JPUPES_Supporting_Data.xlsx (77 sheets) — Summary (n, mean, SD, RSD per group), Raw_Data (replicate observations keyed to Group ID), 70 point-level sheets, Derived_Calculations, Dataset_Index, Dataset_Parameters, README. Sheet 00_SUPERSEDED names the five records that Version 6 supersedes, the sheet that replaces each and the reason; they are retained unchanged. 3. Figure_Table_RawData_Map.xlsx — maps every figure, table and note to its dataset and marks entries that now point to the revision dataset. 4. MANIFEST.md and MD5SUMS.txt. NEW IN VERSION 6 Three-arm demixing with an inert rheology-matched dope and the mature morphology of the three arms; repeat acid-site titration of all five materials with a bridging coupon; bulk CHNS; replicated 168 h total-recycle series with a defined hold-up purge; acid-cycling integrity with the three previously withheld columns restored; extended porometry on a corrected acquisition; three synthetic matrices with recipe and nitrate verification; spent-regenerant neutralisation and membrane leach; HYSCORE at three interpulse delays; energy-dispersive cross-section maps; S 2p speciation of pristine PES. Superseded: Demix_raw, POROMETRY_raw, ENDUR_REP_raw, CYC_INTEG_raw and three rows of Titration_series_raw. One EDS line scan is deposited as EDS_LINE_SUPERSEDED and not used. CONVENTIONS No calendar date or timestamp appears in any file; run timing is elapsed hours from the start of each series (_elapsed_h). SD is the sample SD of the n raw values. Divergences between series are recorded rather than reconciled (README; Notes S9, S30).

Steps to reproduce
Full protocols are in the manuscript (Sections 2.1–2.11) and Supporting Information (Notes S1–S31). This field summarises how the records were generated and how a printed value traces to them. HOW THE DATA WERE GENERATED Membranes were prepared by reactive aqueous nonsolvent-induced phase separation from an NCO-terminated Jatropha-oil-derived precursor, PES and DMF or NMP; water coagulation formed the asymmetric membrane and converted residual NCO into a urethane–urea network. “JPU/PES 50/50” is the precursor:PES mass ratio in the dope. Reaction–demixing coupling was measured on three arms of equal dope viscosity: reactive, end-capped and an inert chain-extended control, by transmitted light (t90/t50/t10) with rapid ATR conversion at the demixing time, and the mature morphology of each arm by FESEM. Compositions were screened against a 0.8 bar burst gate; solvent-specific mapping used a three-factor response-surface design with confirmation runs. Performance: pure-water permeability on ascending and descending ramps, burst pressure, PEG rejection, displacement porometry (thirteen pressures, 0.01–1.0 bar; mean flow pore diameter from the half-dry pressure) and replicated 168 h total-recycle operation with a defined hold-up purge. Copper: 168 h static uptake, 180 min mass balance, single-pass breakthrough in single-solute, multicomponent and three synthetic matrices (recipes and IC nitrate in WW_RECIPE and WW_NO3_IC), five adsorption–regeneration cycles on three independent sequences, spent-regenerant neutralisation and membrane leach. Sites: potentiometric titration with paired coupons, bulk CHNS, S 2p speciation of pristine PES. Distribution: EDS hyperspectral cross-section maps checked against CHNS. Coordination: XPS, Cu K-edge XANES/EXAFS, CW-EPR and HYSCORE at τ = 96, 136 and 176 ns, each with a nitrogen-free control. Dispersion is the sample SD across independently prepared replicates. No calendar date appears in any file; timing is elapsed hours from the start of each series. HOW TO REPRODUCE A PRINTED VALUE 1. Use Figure_Table_RawData_Map.xlsx to find the dataset and file for each figure, table or note; entries added in this revision point to JPUPES_Revision_Dataset.xlsx. 2. Revision values: open the named RAW_* sheet, filter to the group and recompute mean and STDEV.S; the matching QC_* sheet lists the gate each row passed. 3. Original values: in JPUPES_Supporting_Data.xlsx open Summary, then Raw_Data under the same Group ID; non-replicate quantities are in Derived_Calculations with formula and source. 4. Sheet 00_SUPERSEDED lists each superseded record and its replacement; superseded sheets are retained unchanged and not used. 5. Every between-group comparison is registered in Table S87 with family, family size, 95% CI and Welch p before and after Bonferroni correction. Integrity: md5sum -c MD5SUMS.txt
