This data includes a variety of characterisation results for Pickering emulsions stabilised using either anionic TEMPO-oxidised cellulose nanofibrils or cationic cellulose nanofibrils functionalised with a quaternary ammonium group. The emulsions were prepared using sunflower oil either in water or solutions of NaCl to determine effects of fibril charge and salt concentration on the structures present in these emulsions, and how this related to their rheological properties.

Data included in this dataset are

AFM (02/2014): AFM measurements made by Yun Jin on OCNF at 0.8wt% (8gl ox-cell) and OCNF emulsions (beads+cellulose)(.jpg images and compressed text files from instrument)
CLSM (08/2018): CLSM measurements made by Julien Schmitt on OCNF and CCNF stabilised emulsions with 0; 0.1 and 0.5M NaCl. The folder is separated in subfolders, one subfolder per sample (images in .czi format)
Contact angle (2013): three series of contact angle measurements on CONF at the hexadecane/water interface made by Yun Jin (contains .jpg files for the images, and .xls files for analysis of the images)
Mastersizer - OCNF emulsions (2013): Mastersizer measurements made by Yun Jin on OCNF stabilised emulsions. The sub folder "salt effect" contains the measurements made for OCNF at various concentrations with 0; 0.1; 0.5 or 1 M salt (files .xslx; the .txt are the same data treated). The subfolder "pH effect" consists of measurements at pH=3; 5 or 11 at 0.8gL without salt (files .xls, and .tif for graphs).
Mastersizer - CCNF emulsions (2021): measurements made by Zakir Hossain at various pH for CCNF-stabilised emulsions at 1wt% (.xslx file)
Rheology (08-09/2018): Rheology measurements made by Julien Schmitt for dispersions (labeled "D_rheo") and emulsions ("E_rheo") stabilised by OCNF or CCNF at 1wt%. The folder is divided in 2 subfolders (OCNF and CCNF) one for each type of cellulose, while those are divided in 3 subfolders, corresponding to each type of measurement (viscosity, amplitude sweeps and frequency sweeps) Data is given in graphs as .pdf with the data also included as .txt files.
SANS (2019): SANS data for OCNF and CCNF dispersions at 1wt% but also emulsions with different salt concentration. A more complete description is given in the "description of SANS data.txt" file, in the folder. (Data and fit as .dat, .rds or .fit text files, graphed as .pdf or .jpg)
SEM (10/2013): SEM images (.tif files) made by Yun Jin on freeze-dried OCNF stabilised emulsion at 8gL
