ENAC Seminar Series by Prof. G. Biskos
13:15 – 14:15 – Prof. George Biskos
Associate Professor, The Cyprus Institute, CY / Delft University of Technology, NL
Aerosol Science and Technology: An Enabling Discipline for Environmental Sensing
Sensing technologies for probing key parameters in the atmospheric, the aquatic and the terrestrial environment are crucial for assessing natural and anthropogenically-induced changes, and consequently for designing effective strategies to mitigate them. For example, to assess the impacts of fossil fuel burning on climate change we need robust instruments and sensors that can determine the concentrations of gaseous pollutants as well as the physical and chemical properties of the particulate matter emitted by combustion sources in the atmospheric environment.
In the first part of this talk I will provide a brief overview of instruments for characterizing the physical properties of atmospheric aerosol particles, and how these can be combined for probing some of their climate-relevant properties. I will then focus on recent advances that have enabled the development of miniaturized, lightweight and cost-effective – yet highly accurate – instruments that can enable game-changing approaching for characterizing the atmospheric aerosol. The second part of my talk will focus on the synthesis of engineered aerosol nanoparticles and the fabrication of nanomaterials using those as building blocks. Here I will briefly highlight the capabilities of spark ablation, and advances in the recent years that have enabled it as an effective process for the synthesis of nanoparticulate-based materials. I will then demonstrate how the technique can be employed for synthesizing novel metal oxide semiconductor gas sensors that can be employed for air quality monitoring. I will summarize my talk by highlighting new opportunities enabled by the aforementioned technologies, and how these are leading to observational approaches that go far beyond the current state of art.
Short bio:
George Biskos is an Associate Professor at the Cyprus Institute, where he leads the Innovation Department and the Instrumentation for Nanoparticle Synthesis and Characterisation Laboratory of the Climate and Atmosphere Research Centre, and affiliated with the Geosciences and Remote Sensing Department of Delft University of Technology. His research interests fall in the broader field of Aerosol Science and Technology, with activities ranging from designing and building aerosol instrumentation to developing and implementing aerosol-based nanotechnology tools for producing nanomaterials for various applications. Results from these activities have so far led to the creation of three spin-off companies.
George holds an MSc degree in Environmental Science and Engineering (Imperial College, UK), and a PhD in Engineering (Cambridge University, UK). After his PhD studies he has worked as a postdoctoral researcher at Harvard University (USA) and has held faculty positions at the University of the Aegean (Greece), and at Delft University of Technology (Netherlands) before joining the Cyprus Institute.
