Comparative Delivery of 1,8-Cineole and Eucalyptus Oil Using Chitosan Nanoparticles and PVA Nanofibers: A Polymeric Nanotechnology Toolbox for Antibacterial, Wound-Healing, and Ant... by Shetta, Amro AbdelAzeem

“…To address this gap, this thesis investigates a two-level comparative design, (i) a single defined molecule, 1,8-cineole (CIN), versus a compositionally diverse eucalyptus oil (EU), and (ii) one-barrier delivery (direct loading into a polymer matrix) versus a two-barrier architecture (NP-in-NF dual encapsulation) intended to strengthen retention and control diffusion at the biological interface. Chitosan nanoparticles (CS NPs) directly loaded electrospun poly(vinyl alcohol) nanofibers (PVA NFs), and NP-in-NF composite nanofibers (PVA–CS NFs containing bioactive-loaded CS NPs) were formulated and optimized using Box–Behnken designs at both the nanoparticle and electrospinning levels. …”

Modular human-operated radar framework by Carstens, Wilhelm L

“…In evaluating various IoT protocols from literature, the MQTT protocol is selected and then experimentally analysed against pure transport protocols on consumer hardware, characterising their usage. Then, using these technologies, a common framework is designed and developed, alongside a browser-based Human-Machine Interface (HMI) that allows for general usability and performance testing. …”
