The seminar commenced with a warm welcome and introduction of the speaker by Prof. CHEN Qingyan, Director of PAIR. Prof. Pui began his presentation by outlining the recent advancements in nanoparticle technologies, covering instrumentation developments, ISO standards and industry partnerships. He then delved into the applications of nanoparticle technologies in four interdisciplinary areas:
Microelectronics: Contamination control in Extreme UV Lithography (EUVL) systems;
Air Quality: PM2.5 mitigation, respirators, and indoor and urban pollution controls;
Health Effects: Nanomedicine, bioaerosol sensors, UV-C decontamination; and
Filtration: Prediction of filter media performance and wildfire impacts on electret filter efficiency, and large-scale direct-capture of atmospheric CO2 to combat climate change.
In his closing remarks, Prof. Pui highlighted that nanoparticles are involved in multiple disciplines, bringing both benefits and potential harm to the environment, human health and semiconductor manufacturing. He underscored the importance of collaborative fundamental and applied research between academia and industry to foster a sustainable future, urging stronger partnerships among governments, industries and researchers to create a healthier and more prosperous society in the long run.

Prof. Alvarez discussed the emerging opportunities that nanotechnology offers to revolutionise water treatment systems. He explained how it can improve pollutant-removal efficiency, reduce energy consumption, and enable cost-effective decentralised solutions. Illustrative examples included: Electrosorption using highly conductive and selective electrodes to remove multivalent ions that can cause scaling.
Solar-thermal processes, enabled by nanophotonics, to desalinate with membrane distillation.
Disinfection and advanced oxidation using nanocatalysts.
Electrocatalytic degradation of recalcitrant organic pollutants of emerging concern.
In conclusion, Prof. Alvarez affirmed that nanotechnology holds significant promise for advancing sustainable resources management, enabling safe and low-energy water treatment and reuse. He envisioned that high-performance modular systems that would deliver multifunctional solutions with minimal infrastructure requirements.

The seminar commenced with a welcome speech and speaker introduction by Prof. CHEN Qingyan, Director of the PolyU Academy for Interdisciplinary Research (PAIR). In his presentation, Prof. Cao stated that urban environment engineering seeks to apply system engineering to solve complex urban problems. He highlighted that interdisciplinary research that combines scientific and mathematical approaches is crucial for understanding the mechanisms and laws concerning the complex interactions between humans and the ecological environment. Prof. Cao emphasised that the modelling of urban pollution involves a mix of techniques, including remote sensing, big data, computational simulation, the Internet of Things, artificial intelligence, digital twins, etc. He gave various project examples to explain how different techniques can be used for scientific monitoring, fast prediction, assessment and regulation of urban pollution. To conclude, Prof. Cao pointed out that advancements in urban environment modelling and intelligent control can build the scientific foundation for sustainable urban development.

Physicist Geoffrey West has found that simple, mathematical laws govern the properties of cities -- that wealth, crime rate, walking speed and many other aspects of a city can be deduced from a single number: the city's population. In this mind-bending talk from TEDGlobal he shows how it works and how similar laws hold for organisms and corporations.

How does a Drinking water treatment process work?, Drinking water treatment plant process animation: Here working of drinking treatment plants with detailed drinking water treatment processes and unit operations are discussed. Drinking water from the river, pond or local water bodies comes in drinking water treatment plants through various water treatment processes, like aeration, coagulation, filtration, and disinfection, etc. The aim of drinking water treatment is to produce and maintain water that is hygienically safe, aesthetically attractive and palatable in an economical manner. Thus, Before arriving at your tap, drinking water is treated in the drinking water treatment plant.
