This presentation examines processes of subjectification whereby Chinese gods affirm unique personas and engage humans and each other in intersubjective interactions. In so doing, it develops relational approaches to study divine-human sociability. The vast array of ritual techniques developed over the longue durée in China to allow the gods to “talk back” to humans and create bonds have allowed these gods to affirm themselves as persons and subjects – even though there was also resistance against such developments. This lecture will propose an overview of the ritual techniques available for such personification and subjectification processes and their historical development in the Chinese world. It will then explore some of the theoretical and comparative dimensions of such processes and their consequences for our understanding of subjectivity.

Until recently, there were two main ways of obtaining information about words and expressions. The first was to analyze large text data sets (corpora) and calculate the frequency with which words and phrases occur, as well as the typical contexts in which they occur. The second was to ask participants to provide subjective information about words and phrases, such as the familiarity of the stimuli or the age at which they are typically acquired. The development of large language models has given us a third option. Instead of asking participants for information, we can query large language models. The results show that the information obtained from those models is just as good and often even better than the information obtained from people, especially when the model is tuned to a few thousand stimuli.

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. Yao began his presentation with an overview of microwave photonics (MWP), emphasising that the technology uses light as a carrier and photonic and optoelectronic devices for the generation, transmission, control and processing of microwave signals. He compared the properties of four major material systems including indium phosphide (InP), silicon nitride (Si3N4), lithium niobate on insulator (LNOI) and silicon on insulator (SOI), highlighting that SOI, Si3N4, and LNOI are playing important role in implementing photonic integrated circuits (PICs).
Prof. Yao further explored current applications of photonic integrated MWP systems. These included: true time delay networks for wideband beamforming, optoelectronic oscillators for low-phase-noise, high-frequency microwave generation, programmable signal processors for versatile photonic signal processing, high-sensitivity optical sensors and integrated MWP radar, etc.

Lu began his presentation with a brief outline of the role of functional nanomaterials in addressing global challenges and advancing green hydrogen technologies. He highlighted the critical importance of electrodes, membranes, catalysts and photocatalysts in enhancing the efficiency and scalability of electrolysis and photocatalysis systems, as well as the significance of solid-state storage materials in overcoming challenges related to hydrogen storage and distribution, noting that some low-pressure solutions are already in use.
Still, Prof. Lu emphasised that further technological innovations are needed to reduce costs and enhance performance. He explained that green hydrogen is a valuable energy carrier; it can not only contribute to decarbonisation in the power sector, but also act as zero-emission fuel for sea, land and air freight, which is crucial for the achievement of a net-zero future by 2050. In conclusion, Prof. Lu called on the academic community to accelerate the commercialisation of new materials for the construction of cost-effective hydrogen infrastructure, and urged researchers to bridge the gap between technology R&D and practical applications.
