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.

The Virtual Reality (VR) Training for Laser Cutter Operation was developed as a supplementary training tool for the PolyU Library’s technical support staff to practice and become familiar with the operation of a laser cutter. The application simulates the environment, laser cutter model, essential operational procedures, and corresponding responses of our laser cutter in service as realistically as feasible. A computer with a simplified laser cutting software interface was also built to simulate the software operation. Interactions (primarily on/off) with all other peripheral equipment, such as the ventilation system, air compressor, and earmuffs, are triggered through button clicks in an on-screen menu. The application simulates the operational procedures and corresponding reactions of the real laser cutter as closely as necessary. New technical staff members who are trained but not yet proficient with laser cutting can practice safely in an immersive environment enabled by VR technology.

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.

This video is made by Dr. Pearl Lin and Dr. Clare Fung's project, "Great Case of Marketing in the Hospitality and Tourism Industry." A special thanks to Liu Xiaotian, who provided information and insights for this video. This case discusses a marketing strategy that leverages popular online trends and public relations tactics to promote a hotel brand and a major e-commerce platform. The key elements include: 1) Tapping into the widespread popularity of "domineering CEO" and "noble butler" themes in Chinese internet culture and staging a "handsome housekeeper" event to attract attention; 2) Carefully controlling the risks and social perceptions around the event, ensuring it is positioned as a one-time promotional activity rather than a regular hotel service; and 3) Filming the event across different hotel venues to showcase the Sofitel Hangzhou Yingguan property and generate significant exposure on social media platforms. The outcomes indicate significant reach and engagement but highlight the potential risks of such an approach, underscoring the importance of meticulous planning and monitoring to avoid unintended negative consequences.

This video is made by Dr. Pearl Lin and Dr. Clare Fung's project, "Great Case of Marketing in the Hospitality and Tourism Industry." A special thanks to Gao Boyou, who provided information and insights for this video. This case discusses JellyCat, a UK-based doll company that faced challenges in the Chinese market due to its non-local brand identity and high pricing. To address this, JellyCat adopted a new market segmentation strategy, targeting young consumers with higher purchasing power, and implemented an "Ugly as Beauty" reverse marketing approach. This strategy, which leveraged the social attributes of "ugly" things and aligned with the emotional needs of young consumers, helped JellyCat establish a strong brand identity and product features, leading to increased sales and brand loyalty. However, the approach also carries risks, as improper execution could damage the brand's image, and the phenomenal popularity has a time limit, requiring continuous marketing and maintenance efforts.
