RiFood-developed fungus-based fat replacer enables healthy low-fat indulgences

AkkMore™, a novel formula of fat replacer developed by the Research Institute for Future Food (RiFood), has been used in the production of low-fat food products including low-fat ice cream of 3% fat content. The innovation was developed by the team led by Dr Gail CHANG Jinhui, RiFood Core Member, and was awarded silver medal at the 2022 Special Edition of the Geneva International Exhibition of Inventions. AkkMore™ is produced from natural fungal sources, and has been tested for its effectiveness in bringing a number of health benefits, including preventing obesity and other metabolic diseases, enhancing gut health, modulating the immune response, and reducing anxiety. The research team is now working on “Cream Mate”, an AkkMore™-based cream substitute. Cream Mate enables cream products to contain less fat, to be able to be frozen for long time, and to extend shelf-life while holding sensory appeal comparable to traditional cream.  The use of Cream Mate helps reduce calorie and the consumption of dairy products in the desserts, as well as the amount of food waste due to expiration.  This helps food producers to make their production more sustainable and economical. In addition, RiFood is collaborating with Hotel ICON on the use of Cream Mate in preparing reduced-fat desserts to be served on the hotel regular menus, which are available starting on 1 March.

Prof. Ioannis BRILAKIS of University of Cambridge to deliver PAIR Distinguished Lecture on built environment digital twinning

PAIR cordially invites you to join our Distinguished Lecture on 8 March 2024 (Friday) at 3:00 p.m.–4:30 p.m. (Hong Kong Time) on the PolyU campus and via Zoom. The lecture titled “Digital Twinning the Built Environment” will be delivered by Prof. Ioannis BRILAKIS, Laing O’Rourke Professor of Civil & Information Engineering and Director of the Construction Information Technology Laboratory, University of Cambridge.    Digital Twinning methods can produce a reliable digital record of the built environment and enable owners to reliably protect, monitor and maintain the condition of their assets. The built environment is comprised of large assets that need significant resource investments to design, construct, maintain and operate them. Improving productivity, i.e., efficiency and effectiveness, and creating new, disruptive ways to address existing problems throughout their lifecycle can generate significant performance improvements in cost, time, quality, safety, sustainability, and resilience metrics for all involved parties. Creating and maintaining an up-to-date electronic record of built environment assets in the form of rich Digital Twins can help generate such improvements.   This talk introduces research conducted at the University of Cambridge on inexpensive methods for generating object-oriented infrastructure geometry, detecting, and mapping visible defects on the resulting Digital Twin, automatically extracting defect spatial measurements, and sensor and sensor data modelling. The results of these methods are further exploited through their application in design for manufacturing and assembly (DfMA), mixed-reality-enabled mobile inspection, and proactive asset protection from accidental damage.   Prof. Brilakis completed his PhD in Civil Engineering at the University of Illinois, Urbana Champaign in 2005. He then worked as an Assistant Professor at the Departments of Civil and Environmental Engineering, University of Michigan, Ann Arbor (2005-2008) and Georgia Institute of Technology, Atlanta (2008-2012) before moving to Cambridge in 2012 as a Laing O’Rourke Lecturer. He was promoted to Reader in October 2017 and to Professor in 2021. He has also held visiting posts at the Department of Computer Science, Stanford University as a Visiting Associate Professor of Computer Vision (2014) and at the Technical University of Munich as a Visiting Professor, Leverhulme International Fellow (2018-2019), and Hans Fischer Senior Fellow (2019-2023). He is a recipient of the 2022 EC3 Scherer Award, 2022 EC3 Thorpe Medal, 2019 ASCE J. James R. Croes Medal, the 2018 ASCE John O. Bickel Award, the 2013 ASCE Collingwood Prize, the 2012 Georgia Tech Outreach Award, a 2010 NSF CAREER award, and a 2009 ASCE Associate Editor Award.

In his presentation, Prof. Wang first gave some background information about the economics of battery fast charging for electric vehicle (EV), pointing out the importance of fast charging in enabling EV affordability and sustainable electrification. He then highlighted the current challenges in fast battery charging at all temperatures and presented the asymmetric temperature modulation (ATM) approach. The ATM method enables 10-minute fast charging of energy-dense Li-ion batteries at any temperature (even at -60°C) while still delivering remarkable cycle life. Next, he presented the novel thermal management concepts for extremely fast charging in both extreme cold and hot conditions and emphasised the need for battery technology that enables both fast-charging and high-temperature stability. To conclude, Prof. Wang believed that the future of battery technology lies in Lean Energy Storage Systems (LESS) coupled with ubiquitous fast charging, which can provide affordable and safe mobile energy. This would require research development to bring forth a new paradigm of battery design and thermal management without having to trade-off between fast charge, safety, lifetime, and cost. A question-and-answer session moderated by Prof. Li followed. The audience had a fruitful discussion with Prof. Wang. Please click here for an online review:

RISUD develops biomineralisation technique to prevent microbial corrosion in marine structures

Prof. LI Xiangdong, Dean of the Faculty of Construction and Environment, Director of the Research Institute for Sustainable Urban Development, Chair Professor of Environmental Science and Technology, Ko Jan Ming Professor in Sustainable Urban Development and his research team, have successfully developed a novel biomineralisation technique, which can effectively protect marine concrete from microbially induced corrosion, thereby contributing to the achievement of sustainable coastal structures. Sulphate-reducing bacteria (SRB) is a type of anaerobic bacteria which accelerates the production of hydrogen sulphide that can lead to material corrosion and deterioration. The biomineralisation technique developed by the team is an environmentally friendly coating method. It utilises carbon dioxide to produce mineral precipitates on concrete surfaces. This results in the formation of a biomineralised film, which acts as a protective layer to control sulphate diffusion and isolate concrete from the corrosive SRB. This biomineralisation strategy has strong potential for applications in various environments in which microbial corrosion occurs, such as marine environments, sewage environments, and water-cooling utilities. The research “Biomineralization to prevent microbially induced corrosion on concrete for sustainable marine infrastructure” was published in Environmental Science & Technology.  Further reading: https://polyu.hk/OXIRi Read the full article: https://pubs.acs.org/doi/10.1021/acs.est.3c04680
