The interactions in ternary system made of xanthan gum, Carbopol 940 and anionic/nonionic surfactant
The development and optimization of systems consist of polymers and surfactants are strongly related to the presence of interactions between them. Therefore, the interpolymer complexes between biopolymer xanthan gum and synthetic polymer Carbopol 940 were investigated before and after the addition…

Physico-chemical Modification of Gelatine for the Improvement of 3D Printability of Oxidized…
This work explored 3D bioplotting to mimic the intrinsic hierarchical structure of natural articular cartilage. Alginate dialdehyde-gelatine (ADA-GEL) was used as a hydrogel ink to create hierarchically ordered scaffolds. In comparison to previously reported ADA-GEL compositions, we introduce a…

Bio-Based Polyricinoleate and Polyhydroxystearate: Properties and Evaluation as Viscosity Modifiers…
This paper aims to design bio-based polyester as a viscosity modifier for lubricant properties. Bio-based polyricinoleate (PRic) and its saturated homologous polyhydroxystearate (PHS) have been synthesized from fatty acid methyl esters.
The polycondensation performed in bulk in a one-step…

Cellulose and its derivatives for application in 3D printing of pharmaceuticals
Background
Three-dimensional printing (3DP) has emerged as an advanced manufacturing technology capable of producing complex yet precise medicines intended for patient-centric drug therapy. However, printable materials currently available for 3DP are far too limited.
Area covered
The current…
