This study shows the advantages of a microwave assisted crosslinking process for the preparation of hydrogel-forming microneedle arrays. The arrays prepared using the microwave assisted process had equivalent properties to those prepared conventionally but can be produced 30 times faster. Thus, the use of microwave radiation significantly reduces the time required for MN preparation and, in addition, microwave thermal processes are cheaper and quicker than conventional (oven) heating. Therefore, the findings in this paper are of interest for MN crosslinking applications, leading to shorter, cheaper and greener manufacturing processes.

An approach using the nanomorphology of polymer blends in light-scattering thermosetting plates based on self-assembly was demonstrated without using the conventional approach of blending nanoparticles such as silica sol, zirconia sol, phosphor, or chromophore into the polymer matrix. Light-scattering was controlled by molecular weights of poly(acrylic acid).

This study demonstrates that the predicted elongational viscosities of proposed equations are larger than those of Cogswell's equations, Binding's equations, and Gibson's equations, and are close to the experimental results.
- Laccase-Assisted Approach to Graft Multifunctional Materials of Interest: Keratin-EC Based Novel Composites and their Characterisation
Hafiz M. N. Iqbal, Godfrey Kyazze, Thierry Tron and Tajalli Keshavarz

This study focuses on the evaluation of raw keratin as a potential material to develop composites with novel characteristics. Herein, we report a mild and eco-friendly fabrication of in-house extracted feather keratin-based novel composites consisting of ethyl cellulose as a backbone material.
- Effect of Oligo-Hydroxyalkanoates on Poly(3-Hydroxybutyrate-co-4-Hydroxybutyrate)-Based Systems
