3D printed polymers are less stable than injection moulded counterparts when exposed to terminal sterilization processes using novel vaporized hydrogen peroxide and electron beam processes.
Chen, Yuanyuan; Neff, Martin; McEvoy, Brian; Cao, Zhi; Pezzoli, Romina; Murphy, Alan; Gately, Noel; Hopkins Jnr, Michael; Rowan, Neil J.; Devine, Declan M. (Elsevier, 2019-11-21)There is an increasing trend for use of 3D printing processes in healthcare due in part to emergence of customised medical devices and associated low manufacturing cost. However, there is a dearth of knowledge on the ... -
Designing sustainable polymer blends: tailoring mechanical properties and degradation behaviour in PHB/PLA/PCL blends in a seawater environment
Engler, Leonardo; Farias, Naiara C.; Crespo, Janaina S.; Gately, Noel M.; Major, Ian; Pezzoli, Romina; Devine, Declan M. (MDPI, 2023-06-29)Biodegradable polyesters are a popular choice for both packaging and medical device manufacture owing to their ability to break down into harmless components once they have completed their function. However, commonly used ... -
Development of sustainable flexible packaging solutions using novel biodegradable and compostable polymer blends
Farias, Naiara; Devine, Declan; Fournet, Margaret Brennan; Pezzoli, Romina (BioICEP, 2020-10-19)Plastic packaging has changed positively the way food products are delivered, reducing poverty and hunger due to the better protection of the goods, allowing their preservation for longer times throughout their supply ... -
Investigation of miscibility estimation methods between indomethacin and poly(vinylpyrrolidone-co-vinyl acetate).
Pezzoli, Romina; Lyons, John G.; Gatley, Noel; Higginbotham, Clement L. (Elsevier, 2018)The investigation of the miscibility between active pharmaceutical ingredients (API’s) and polymeric excipients is of great interest for the formulation and development of amorphous solid dispersions, especially in the ... -
Micro-injection moulding of poly(vinylpyrrolidone-vinyl acetate) binary and ternary amorphous solid dispersions.
Pezzoli, Romina; Hopkins, Michael Jnr.; Direur, Guillaume; Gatley, Noel; Lyons, John G.; Higginbotham, Clement L. (MDPI, 2019-05)Micro-injection moulding (µIM) was used for the production of enteric tablets of plasticised and unplasticised solid dispersions of poly(vinylpyrrolidone-vinyl acetate) (PVPVA), and the effect of the mechanical and thermal ... -
Stability studies of hot-melt extruded ternary solid dispersions of poorly-water soluble Indomethacin with Poly(vinyl pyrrolidone-co-vinyl acetate) and polyethylene oxide.
Pezzoli, Romina; Lyons, John G.; Gatley, Noel; Higginbotham, Clement L. (Elsevier, 2019-08)This investigation aims to evaluate the effect of moisture and temperature on the physical stability and dissolution behaviour of hot-melt extruded binary and plasticised ternary solid dispersions. Poorly water-soluble ... -
Sustainable antimicrobial polymeric food packaging and anti-infection medical catheter preparation using antimicrobial peptide and Ag+ nanoreservoir formulations
Lanzagorta Garcia, Eduardo; Pezzoli, Romina; Rodriguez Barroso, Laura G.; Venkatesh, Chaitra; Devine, Declan M.; Brennan Fournet, Margaret E. (Athlone Institute of Technology, 2020-06)New antimicrobial interventions are urgently required to combat rising global health and medical infection challenges. Here, an innovative antimicrobial technology, providing price competitive alternatives to antibiotics ... -
Synthesis and characterisation of novel temperature and pH sensitive physically crosslinked poly(N-vinylcaprolactam-co-itaconic acid) hydrogels for drug delivery.
Fallon, Megan; Halligan, Shane; Pezzoli, Romina; Geever, Luke; Higginbotham, Clement (MDPI, 2019-08-29)Previous studies involving poly N-vinylcaprolactam (PNVCL) and itaconic acid (IA) have synthesised the hydrogels with the presence of a solvent and a crosslinker, producing chemically crosslinked hydrogel systems. In this ...
