3. Description of the project
Projects "Smart biolubricants with electro‑responsive capability based on lignocellulosic nanoparticles" (UHU-1255843) and "Advances in the control of friction and wear under the action of an electric field with electro-sensitive and sustainable lubricants" (UHU-202008), funded by Programa Operativo FEDER Andalucia 2014-2020, call 2018 and 2020, respectively. They were led from the University of Huelva, and mainly developed at Center for Research in Chemical Products and Process Technology (Pro2TecS). Main objective: Using vegetable oils and lignocellulosic nanoparticles from residual biomass to produce stable dispersions with tunable electrorheological and tribological properties.

4. Description of the dataset
This dataset reports the thermo-rheological behavior of sustainable oleogels prepared by dispersing cellulose nanofibers, both mechanically refined and TEMPO-mediated oxidation chemically treated, from bleached elm kraft pulps in castor oil (1.4 wt.%). A methanol-mediated solvent-exchange method was used to transfer the nanofibers from hydrogel to oil. Rheological data under linear and non-linear shear conditions highlight the influence of the nanofibrillation pre-treatment on mechanical stability, shear resistance, temperature sensitivity, and structural recovery of the oleogels.

METHODOLOGY
--------------------------
1. Methodology
Cellulose nanofibers, both mechanically refined and TEMPO-mediated oxidation chemically treated, were obtained from bleached elm kraft pulps and supplied as aqueous gel suspensions. Oleogels were prepared by transferring these nanofibers into castor oil (1.4 wt.%) via a methanol-mediated solvent-exchange method that displaced water and enabled their dispersion in the oil. The thermo-rheological behavior of the resulting oleogels was characterized through viscous flow and small/large amplitude dynamic shear tests over a range of temperatures and stress conditions to evaluate the influence of the nanofibrillation pre-treatment on shear resistance, temperature sensitivity, and structural recovery.
