Electrochemical Detection Of Nitrite Based On Iron Oxide–Reduced Graphene Oxide Nanocomposite Modified Electrode In Real Water, Amira Ghezal, Zina Fredj, Ammar Al-Hamry, Marcos A. Gross, Leonardo G. Paterno, Mounir Ben Ali, Olfa Kanoun, Baljit Singh

Research Outputs: 2025-Present

This work presents a screen-printed carbon electrode (SPCE) modified with iron oxide nanoparticles-reduced graphene oxide (ION-rGO) nanocomposite for the rapid and highly sensitive determination of nitrite in real water samples. The presence of both ION and rGO on the electrode surface enhances the sensing performance compared to the unmodified SPCE by reducing the charge transfer at the electrode/electrolyte interface. Under optimized conditions, it is demonstrated that the charge-transfer resistance determined from electrochemical impedance spectroscopy (EIS) scales linearly with the logarithm of nitrite concentration. Due to its unique structure, the proposed nitrite sensor displays improved performance compared to our previous work, …

Exploring The Sustainability Of Single Use Plastics In The Biopharmaceuticals Sector: A Scoping Review Of Challenges, Opportunities And Impact, Cormac Mcmahon, Adrienne F. M. Fleming, Philip Owende, Malcolm Goggin

Articles

Single-use plastics (SUPs) are synonymous with the biopharmaceuticals sector, facilitating economies of scale, process efficiency, flexibility and sterility assurance, all with a seemingly negligible environmental footprint. Yet, in ever-tightening regulation, mandated by the Sustainable Development Goals (SDGs) and by concern for large-scale industrial impacts, the sustainability of SUP consumption is increasingly being questioned. Whilst the sector contributes to human welfare, its transition risk is unlikely to remain immune to societal pressure for more sustainable production. This paper aims to present a scoping review of the apparent contradiction between sectoral SUP adoption and the increasing importance of circularity. The approach to …

Internally Stowed, Radially Deployed Radiator Panels For Passive Cubesat Thermal Control, Josh R. Cannon, Kyle N. Havey, Noah S. Housley, Rydge B. Mulford, Brian D. Iverson

Faculty Publications

CubeSats experience significant thermal loads due to solar irradiation and the dissipation from electrical components. The high heat dissipation per unit volume can lead to mission failure if not properly managed. Deployable radiators that are externally stowed and passively actuated in response to changes in CubeSat temperature have been explored as a viable solution. This work describes a radially deployed fin array that is stowed within the CubeSat body when the required heat dissipation is low and passively deploys when the required heat dissipation is high. Internal stowage improves thermal transport to the deployable fins and minimizes heat loss when …

Understanding Urban Cultural Festivals As Social Infrastructure, Bernadette Quinn

Research Outputs: 2025-Present

This paper is concerned with the role that urban cultural festivals play in enhancing the quality and vitality of social life. It acknowledges that their reputation has become tarnished in recent years and that festivals now frequently feature in debates because they are charged with inciting tensions, exclusions and contestations. However, of note here is that cities tend to narrowly conceive of festivals as temporarily bounded moments of commodifiable spectacle. The fact that festivals function, on an ongoing manner, as embedded, sustained practices capable of supporting urban social living in numerous ordinary ways is rarely acknowledged, much less prioritised. This …

Synthesising Cross-Speaker Data For Low-Resource Pathological Speech Recognition With Peft, Kesego Mokgosi, Milad Dadgar, Cathy Ennis, Robert Ross

Conference papers

Dysarthric speech recognition is essential for enhancing communication and accessibility for individuals with speech impairments, yet its development is hindered by a scarcity of robust, speaker-specific datasets. This study explores low-resource dysarthric speech recognition through cross-speaker transfer using synthetic data and parameter-efficient fine-tuning (PEFT). We integrate SpeechT5 text-to-speech (TTS) synthesis with x-vector speaker embeddings to generate speaker-specific dysarthric speech, enabling model adaptation while preserving pathological speech characteristics such as prosodic irregularities. Experiments on the TORGO dataset show that mixed cross-synthetic data with LoRA fine-tuning achieves a WER of 0.17, representing a 71.7% improvement over the standard model (0.60 WER) without …
