The lecture will explore the role of technology in promoting environmental sustainability. It focuses on the development and implementation of innovative technologies that can help address environmental challenges and contribute to a more sustainable future.We are developing green technologies to benefit sustainable environment, which will enable people and the environment to prosper together. The Center for Filtration Research (CFR) at the University of Minnesota, collaborating with 20 leading international filtration manufacturers and end users, was established to develop green technologies to mitigate PM2.5, VOCs, ozone and other environmental pollutants. CFR investigators perform fundamental and applied research on air, gas and liquid filtration. The current research projects include indoor air cleaning and Covid prevention, bioaerosols sensor development and evaluation, nanofiber production and modeling, nanotechnology and instrumentation developments, among others. Large-scale air cleaning towers are established in Xi’an and Yancheng in China, and two additional towers in Delhi, India. They are developed to mitigate PM2.5 pollutants in urban air. The second-generation tower in Yancheng is developed to reduce not only the PM2.5 but also CO2 in the atmosphere. The construction of a set of large-scale air cleaning towers to capture 16 million tons of CO2 annually is proposed. All these research and development activities are helping to improve sustainable environment.

A rapidly expanding research area involves the development of routes to shape programmable three-dimensional (3D) structures with feature sizes in the mesoscopic range (that is, between tens of nanometres and hundreds of micrometres). A goal is to establish methods to control the properties of materials systems and the function of devices, through not only static architectures, but also morphable structures and shape-shifting processes. Soft matter equipped with responsive components can switch between designed shapes, but cannot support the types of dynamic morphing capabilities needed to reproduce continuous shape-shifting processes of interest for many applications. Challenges lie in the establishment of 3D assembly/fabrication techniques compatible with wide classes of materials and 3D geometries, and schemes to program target shapes after fabrication.
In this talk, Prof. HUANG Yonggang will introduce a mechanics-guided assembly approach that exploits controlled buckling for constructing complex 3D micro/nanostructures from patterned two-dimensional (2D) micro/nanoscale precursors that can be easily formed using established semiconductor technologies. This approach applies to a very broad set of materials (e.g., semiconductors, polymers, metals, and ceramics) and even their heterogeneous integration, over a wide range of length scales (e.g., from 100 nm to 10 cm). To allow realisation of 3D mesostructures that are capable of qualitative shape reconfiguration, Prof. HUANG devises a loading-path controlled strategy that relies on elastomer platforms deformed in different time sequences to elastically alter the 3D geometries of supported mesostructures via nonlinear buckling. Prof. HUANG will also introduce a recent work on shape programmable soft surface, constructed from a matrix of filamentary metal traces, driven by programmable, distributed electromagnetic forces that follow from the passage of electrical currents in the presence of a static magnetic field. Under the guidance of a mechanics model-based strategy to solve the inverse problem, the surface can morph into a wide range of 3D target shapes and shape-shifting processes. The compatibility of these approaches with the state-of-the-art fabrication/processing techniques, along with the versatile capabilities, allow transformation of diverse existing 2D microsystems into complex configurations, providing unusual design options in the development of novel functional devices.

The idea of translanguaging has disrupted much of the thinking about language, communication and learning and raised some fundamental questions about human language and human cognition. One of these questions concerns an assumption that seems to underlie a great deal of the work on intercultural communication, and that is, speakers of different named languages not only use language differently, but also think differently and have different worldviews. In this talk, I want to invite the participants to rethink about this issue, from the perspective of Translanguaging, which posits that bilinguals and multilinguals do not think unilingually and thinking goes beyond named languages and indeed beyond what has traditionally been conceived as linguistic versus non-linguistic processes. I offer my views on the existing work in intercultural communication and cross-linguistic studies of cognitive processing and Linguistic Relativity. Implications of this common-humanity-based conceptual stance for intercultural communication including business and workplace lingua franca communication, as well as for language learning and pedagogy, and research design are discussed.

Humans have long tried to make artificial versions of themselves. It is now well established that we attribute human-like states to artificial others. However, the effect of interacting with artificial minds and bodies on the human sense of self and self-identity is less understood. In this talk I will present theoretical and empirical work looking at embodied joint agency in human/ human versus human/ robotic and virtual agents. Specifically, I will outline the key role of the human embodiment and sense of self in establishing joint agency with artificial others. I will discuss key implications of these claims on recent efforts to design autonomous and interactive artificial others. I will introduce the notion of ‘hybrid agency’ to describe these new, technologically mediated ways to embody and control in tandem human and artificial minds and bodies in real and virtual environments.

The seminar commenced with a welcome speech and speaker introduction by Prof. WANG Zuankai, Associate Vice President (Research and Innovation) of PolyU. This was followed by Prof. Leng’s presentation. He first provided a brief background about shape memory polymers (SMP), pointing out that these smart materials can reversibly change between permanent and temporary shapes in response to changes in external stimuli such as temperature. Next, he gave an overview of the researchers from different scientific research institutions and universities around the world who specialise in SMP research, and the types of SMP materials that HIT researchers focus on. He said that SMP are hard to actuate and their recovery strength and speed are low, and so relevant solutions to these challenges are important for the development of SMP composites (SMPC). Prof. Leng then gave examples demonstrating how SMPC can be prepared through actuation methods involving different stimuli such as heat, electricity, magnetism, radio frequency, solution/water, light, etc. He mentioned that SMPC can be used to prepare various structures for aerospace, smart manufacturing, photoelectric applications, microelectromechanical systems applications, and smart clothing. After that, Prof. Leng introduced 4D printing, a novel additive manufacturing process for producing printed objects that can adaptively change their configurations/properties in response to external stimuli. He mentioned that 4D printing is important for producing a range of SMPC-based materials for biomedical applications. To conclude, Prof. Leng said that SMP research is a fast-growing emerging research field. He anticipated that shape memory smart structures incorporated with sensors, actuators, and controllers, would be widely used in aerospace, civil aviation, automotive, energy and daily life.
