3. Description of the project 
Project "Smart biolubricants with electro-responsive capability based on lignocellulosic nanoparticles", (UHU- 
1255843), funded by Programa Operativo FEDER Andalucia 2014-2020, call 2018. It was led from the University 
of Huelva, and mainly developed at Center for Research in Chemical Products and Process Technology 
(Pro2TecS). Main objectives: developing electro-responsive biolubricants from used vegetable-oil fractions 
and lignocellulosic nanoparticles; optimizing their dispersion; evaluating their electrorheological and tribological 
performance; examining how particle properties and temperature influence their behavior. 
4. Description of the dataset 
Sustainable oleogels were developed by dispersing cellulose nanofibrils from elm kraft pulps into castor oil, 
achieving grease-like rheology at only 1.4 wt.%. A methanol-based solvent-exchange method enabled 
transferring never-dried nanofibrils into oil without aggregation. Mechanical and TEMPO-oxidized nanofibers 
produced homogeneous and storage-stable oleogels. These results highlight the suitability of the methanol? 
??based solvent-exchange method to obtain nanocellulose-based biogreases and the potential of these oleogels 
as eco-friendly lubricating greases for industrial use.

METHODOLOGY 
-------------------------- 
1. Methodology 
Cellulose nanofibers were produced from elm pulps via kraft pulping, bleaching, and either mechanical (PFI + 
microfluidization) or chemical (TEMPO) pretreatments. Nanofibers were characterized through composition 
analysis, AFM, XRD, and water-sorption isotherms. Oleogels were prepared by transferring aqueous CNF 
hydrogels into castor oil using a methanol-based solvent-exchange protocol, followed by vacuum solvent 
removal. Final oleogels were evaluated by SEM, DSC, TGA, penetration testing, and rheology to assess structure, 
stability, and lubrication-relevant properties.
