Effect of mechanical recycling on the mechanical properties of PLA-based natural fiber-reinforced composites
Finnerty, James; Rowe, Steven; Howard, Trevor; Connolly, Shane; Doran, Christopher; Devine, Declan M.; Gatley, Noel M.; Chyzna, Vlasta; Portela, Alex; Bezerra, Gilberto S.N.; McDonald, Paul; Colbert, Declan Mary (MDPI, 2023-04-06)The present study investigates the feasibility of utilizing polylactic acid (PLA) and PLAbased natural fiber-reinforced composites (NFRCs) in mechanical recycling. A conical twin screw extrusion (CTSE) process was utilized ... -
Heat dissipation plays critical role for longevity of polymer-based 3D-printed inserts for plastics injection moulding.
Moritz, Vicente; Bezerra, Gilberto S.N.; Hopkins, Michael Jnr.; Fuenmayor, Evert; Günbay, Suzan; Hayes, Conor; Lyons, John G.; Devine, Declan M. (MDPI, 2022-10-08)Injection moulding is a polymer processing method of choice for making plastic parts on industrial scale, but its traditional mould is made from tooling steel with time-consuming and costly production. Additive manufacturing ... -
Micro-injection mouding of PEO/PCL blend-based matrices for extended oral delivery of Fenbendazole
Bezerra, Gilberto S.N.; Goetten de Lima, Gabriel Goetten; Colbert, Declan M.; Halligan, Elaine; Geever, Joseph (MDPI, 2023-03-10)Fenbendazole (FBZ) is a broad-spectrum anthelmintic administered orally to ruminants; nevertheless, its poor water solubility has been the main limitation to reaching satisfactory and sustained levels at the site of the ... -
Modulation of the lower critical solution temperature of thermoresponsive poly(N-vinylcaptrolactam) utlizing hydrophilic and hydrophobic monomers
Halligan, Elaine; Zhuo, Shuo; Colbert, Declan Mary; Alsaadi, Mohamad; Tie, Billy Shu Hieng; Bezerra, Gilberto S.N.; Keane, Gavin; Geever, Luke M. (MDPI, 2023-03-23)Four-dimensional printing is primarily based on the concept of 3D printing technology. However, it requires additional stimulus and stimulus-responsive materials. Poly-N-vinylcaprolactam is a temperature-sensitive polymer. ...
