(1) Fuel cell technologies (2) Sustainable treatment of wastewater, (3) Emerging contaminants (microplastics, antibiotics) detection and removal and (4) Impacts of human activities on water quality and ecology. Prof Xiao is co-leading a study with two other colleagues to study microplastics (MPs) release from plastics products. The study led to several papers published in journals such as Nature Food and Chemical Engineering Journal, 4 patents (one filed, three pending) and a SFI Plastic Challenge Award. The findings were featured in more than 300 national and international news outlets and media such as CCTV4, Guardian, BBC, NPR. Prof Xiao is leading a multidisciplinary team to develop next generation energy neutral wastewater treatment technologies. The study led to one Trinity College Provost Project Award, an Intel Bursary Award, ESAI Undergraduate of the Year award, one best conference paper award, one best MAI project award, and numeral publications numeral papers published in journals such as Water Research and Chemical Engineering Journal and two patents (one licensed to an international company and another is pending). Prof Xiao designed a show garden in Bloom 2019, Phoenix Park, Dublin, Ireland in June 2019, which integrated the garden design with the next generation energy neutral wastewater treatment technologies. This award-winning garden was visited by the prime minister of Ireland and more than 100,000 people, and featured in Irish national TV channel RTE and dozens of median. Prof Xiao also developed a wastewater treatment unit for the treatment of wastewater from 300 population and the technology was licensed to an international company. Prof Xiao developed the Burrishoole peatland forest research facility in Co. Mayo, Ireland. The facility includes 4 well equipped catchments for research of impact of peatland forest on soil erosion, water quality and ecology. Mitigation methods and technologies can be tested and validated in a catchment scale using the facility. 4 mitigation methods were successfully tested and validated in the facility by Prof Xiao and his team. Some of the methods were adopted by the stakeholders and decision makers such the Irish Department of Agriculture and Coiltte.

  Summary

  Raman spectroscopy provides the fingerprint to identify molecules. However, the weak signal is a technical barrier. To overcome this weakness, a graphene microsphere enhanced Raman spectroscopy (GMERS) technology has been developed in TCD. The GMERS delivers numerous advantages including a clean signal, stable response, intrinsic inertial reference, flexibility and "step-change" refreshable property, presenting a cutting-edge opportunity for highly sensitive and reliable quantitative analysis. This gives advantages over traditional surface enhanced Raman spectroscopy (SERS) substrates with much low cost. With multiple potential applications, the technology is capable of taking existing practices such as grab-sampling in the environmental sector, which is both labour and time intensive, and proposes replacing it with continuous detection and immediate identification of multiple trace elements under constant flow

  Investigation into the causes, impacts and measures to deal with algal blooms in Vartry Reservoirs (project PI)
  Summary

  Diatom algal blooms in water supply sources can cause many problems in the drinking water treatment process. Vartry Reservoir is an important drinking water source in Ireland. Diatom algal blooms have caused problems in the sand filters in the Roundwood water treatment plant since 2007 (except 2010). In 2013 and 2014, the situation worsened and serious spring diatom algal blooms occurred, with peak concentrations of diatom algal up to 1750 and 2457 counts/ml, respectively, resulting in serious clogging of the slow sand filters and a reduction in treatment capacity from 75 million litres to 40 million litres per day and consequently water shortages in the North Wicklow and South Dublin area two years in a row. In addition, diatom algal blooms might also contribute to the high THMs in the Vartry Water Supply Scheme. Therefore, the aim of the proposed study is to investigate the cause of the diatom algal blooms in Vartry Reservoir and to identify potential measures to deal with the impact of algal blooms in Roundwood water treatment plants. This proposed project is important not only for the Vartry Water Supply Scheme but also for water supplies nationwide, as more than 70 mesotrophic lakes are used as water supply sources in Ireland.

  FORSITE Critical Biomass Removal on Irish Forest Soils
  Summary

  The recent European directive on the promotion of energy from renewable sources sets a mandatory target of 20% of energy from renewable sources by 2020. This need is driving bioenergy use from forests. However, concerns exist about the effects of brash removal on the sustainability of forest ecosystems. In this project, a new concept is introduced, of critical biomass removal, which is the quantitative amount of long-term biomass removal below which impacts to nutrient supply will not occur according to current knowledge.

  Microbial Fuel Cells based system for pollutants removal, resources recovery and disinfection
  Summary

  The secondary treatment process in a conventional wastewater treatment plant usually involves aeration and sludge/flow return, therefore has high energy demand. Microbial fuel cells (MFCs) technology has great advantages over the current technologies used in the secondary treatment process due to its potential for simultaneously harvesting electric energy and removing pollutants and its low sludge production rates. Though numerals attempts, MFCs technologies are still in the laboratory and pilot scales so far, due to the difficulty of scaling up the system to industrial level and the high cost of the cathodes. In this project, the applicants proposed a "Microbial Fuel Cells based wastewater treatment system for pollutants Removal, resources Recovery and Disinfection (MFCs-R2D)", which will overcome the above challenges. The system can be easily increased to large scale for small and medium wastewater treatment plants.

  E3 garden for Bloom 2019
  Summary

  To develop an E3 garden in Bloom Garden Festival 2019, by integrating the technologies with garden design, to demonstrate the great potential of E3 in sustainable development. The theme of our garden would be "E3, water, climate change & sustainable development". The Bloom Garden Festival (see bloominthepark.com) is Ireland's biggest garden and horticulture show. It provides showcase for garden plants, garden design, construction, horticulture and gardening and attracts over 120,000 visitors each year and a huge media interest. We will use the garden to highlight the technologies we developed in the Department of Civil, Structural and Environmental Engineering. In this E3 garden, wastewater will be treated and re-used for gardening and farming, and electricity will be generated by using the wastewater to power the wastewater treatment system. It is expected that this garden will attract great attention as it not only promote sustainable development but also is relevant to public's daily life. In summer 2018 due to the long period of hot and dry weather, water restriction had been posted to the whole country and watering gardens was banned. It is expected such events will occur more frequently due to climate change. This E3 garden will provide solutions to deal with the water shortage.

  Microbial Fuel Cells technologies for urine glucose monitoring
  Summary

  In this proposal we will provide an automatic, convenient and near-zero maintenance required system for long-term continuous urine glucose level monitoring, which can facilitate detection of diabetes in an early stage. Our urine fuel cells (UFCs) system can be installed within the toilet or urinal bowl. Every time the user goes to the toilet, the UFCs will automatically detect the glucose level in urine and show it in a small screen. The data can be stored in the system and events uploaded to mobile phone or computer through a wifi network. If glucose is detected in the urine multiple times - it indicates the user may have diabetes - the system will remind the user to go to see the doctor for further diagnosis. This is a non-intrusive test and doesn't require the user to alter their habits. The success of the project will facilitate the treatment of diabetes in the world.
