Quantitative TEM analysis of a hexagonal mesoporous silicate structure

Hudson, Sarah P.; Tanner, David A.; Redington, Wynette; Magner, Edmond; Hodnett, Benjamin K.; Nakahara, Shohei (Royal Society of Chemistry, 2006)

TEM analysis of mesoporous materials is generally undertaken to give qualitative results. Accurate quantitative analysis is demonstrated in this study. A systematic image analysis of a powder form of a hexagonal mesoporous ...
A radiopaque nanoparticle-based ink using PolyJet 3D printing for medical applications

Shannon, Alice; O'Connell, Aine; O'Sullivan, Aidan; Byrne, Michael; Clifford, Seamus; O'Sullivan, Kevin Jeremiah; O'Sullivan, Leonard (Mary Ann Liebert, 2021)

The aim of this study was to develop a 3D printable radiopaque ink and successfully print a finished artifact. Radiopaque 3D printing would be hugely beneficial to improve the visibility of medical devices and implants, ...
Ranking the effects of cycle time parameters, shoulder posture and load, on shoulder discomfort in a single experiment using Taguchi methods

Browne, Aleksandra; O'Sullivan, Leonard (Cogent OA, 2017)

The purpose of this study was to use the Taguchi Design of Experiments approach to investigate the effects of five risk factors on ratings of shoulder discomfort in a single study. The development of shoulder MusculoSkeletal ...
Rationale, implementation and evaluation of assistive strategies for an active back-support exoskeleton

Toxiri, Stefano; Koopman, Axel S.; Lazzaroni, Maria; Ortiz, Jesús; Power, Valerie; de Looze, Michiel P.; O'Sullivan, Leonard; Caldwell, Darwin G. (Frontiers Media, 2018)

Active exoskeletons are potentially more effective and versatile than passive ones, but designing them poses a number of additional challenges. An important open challenge in the field is associated to the assistive ...
Reconceptualising PCK research in D&T education: proposing a methodological framework to investigate enacted practice

Doyle, Andrew; Seery, Niall; Gumaelius, Lena; Canty, Donal; Hartell, Eva (Springer, 2018)

Since first conceived, the concept of pedagogical content knowledge (PCK) has attracted much attention. Despite being lauded by educationalists as the unique knowledge base of teachers, research on the concept over the ...
