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 ... -
Alfa fiber/polypropylene composites: Influence of fiber extraction method and chemical treatments.
Labidi, Khaled; Cao, Zhi; Murphy, Alan; Hamzaoui, Ahmed Hichem; Devine, Declan M. (Wiley, 2019-01)Alfa fiber/polypropylene composites were manufactured using twin-screw extrusion. Fibers were extracted following alkaline and steam explosion methods. Three chemical treatments were also applied to alkaline extracted ... -
Characteristics of the treated calcium carbonate particles with stearic acid using different treating methods.
Cao, Zhi; Daly, Michael; Clémence, Lopez; Major, Ian; Higginbotham, Clement L.; Devine, Declan M. (Elsevier, 2016-08)Calcium carbonate (CaCO3) is often treated with stearic acid (SA) to decrease its polarity. However, the method of application of the SA treatments has a strong influence on their interface structure and distribution. ... -
Effect of Chemical Treatments and HDPE-g-MA on the physical and mechanical behaviour of HDPE/ natural fibre composites.
Cao, Zhi; Peyregne, Marc; Daly, Michael; Mullen, Tom; Devine, Declan M.; Geever, Luke; Higginbotham, Clement L. (2013)Many authors have reported on the use of natural fibres (raw or chemically modified) as reinforcing elements for high density polyethylene (HDPE). These materials have generated a lot of interest due to their low cost ... -
Nanofillers can be used to enhance the thermal conductivity of commercially available SLA resins.
Hu, Guang; Cao, Zhi; Hopkins, Michael; Lyons, John G.; Brennan-Fournet, Margaret; Devine, Declan M. (Elsevier, 2019-06)Stereolithography (SLA) is a form of 3D printing technology used for the production parts and patterns in a layer by layer fashion. Traditionally, 3D printing has been used for the manufacture of prototypes, however it is ... -
Preparation of biodegradable poltyethylene glycol dimethacrylate hydrogels via thiol-ene chemistry.
Burke, Gavin; Cao, Zhi; Devine, Declan M.; Major, Ian (MDPI, 2019-08-13)Through the control of the molecular weight, water content and monomer concentration, polyethylene glycol dimethacrylate (PEGDMA) based hydrogels have been adapted for numerous applications, including as structural scaffolds, ... -
Synthesis and characterization of high density polyethylene / peat ash composites.
Cao, Zhi; Daly, Michael; Geever, Luke M.; Higginbotham, Clement L.; Devine, Declan M. (Elsevier, 2016-06)A new type of polymer composite was synthesized from one industrial waste, peat ash, at varying mixing ratios of high density polyethylene (HDPE) and the resulting products were characterized using different experiments ...
