CBI research outcome presented at the Greater Bay Area Science Forum
From 16 to 18 November, the 2024 Greater Bay Area Science Forum was held simultaneously in Guangdong, Hong Kong and Macao. Themed on "Leading through Open Science ", the forum attracted over 100 top scholars from the world, including Nobel Prize winners, Fields Medal winners, and renowned academicians from both domestic and international backgrounds, to collaboratively explore cutting-edge topics.
As an important part of research at the University of Nottingham Ningbo China (UNNC), the Nottingham Ningbo China Beacons of Excellence Research and Innovation Institute (referred to as "the China Beacons Institute") was invited to attend to the forum. The China Beacons Institute demonstrated its cutting-edge scientific research progress in Intelligent Manufacturing, Green Chemicals and Energy and Life Science and Healthcare, and presented its ‘Beacons Wisdom’ in technological innovations including rare-earth-less motor control system solutions, 3D printing, energy storage and new energy, waste recycling, and wearable medical devices.
Intelligent manufacturing solutions for cost reduction and efficiency: rare-earth-less motor and 3D printing
Currently, new materials and technologies empower the transformation and upgrading of the manufacturing industry. In industry field, the rare earth permanent magnet-assisted synchronous motors, with features of high efficiency, energy saving and small size, provide strong power support in aerospace, electric vehicles, wind power generation and other fields.
However, rare earth, as an important material for permanent magnet-assisted synchronous motors, making motors costly and unstable in supply since its high price and uneven resource distribution. To tackle this challenge, Dr Shuo Wang, Assistant Professor at the China Beacons Institute, demonstrated a set of ultra-efficient rare-earth-less motor permanent magnet-assistant motors, which provides the motor industry with new ideas to reduce costs and increase efficiency.
Dr Shuo Wang explains, “This newly developed motor uses ferrite magnetic sheets instead of rare earth permanent magnets, which has obvious advantages in terms of cost, performance and efficiency. Specifically, the material cost of ferrite magnets is only 1/10 of rare earth permanent magnets, which greatly reduces the overall price of the motor. In terms of performance, ferrite magnetic sheet has a good barriers and ribs optimised rotor designs with higher power factor and efficiency, which make a more effective conversion of electrical energy into mechanical energy, reducing energy loss.” Dr Wang Shuo believes that reducing the dependence on rare earth will become one of the development trends in the motor industry in the future.
In addition, simulation technology also brings new opportunities for the additive manufacturing industry to reduce costs and increase efficiency. Dr Yi Nie and Dr Yinfeng He, Assistant Professors in Intelligent Manufacturing at the China Beacons Institute, demonstrated a batch of 3D printing results using advanced simulation-driven structural material design, which have fine structure and excellent performance, and have a wide range of prospects for application in aerospace, energy, and biomedical fields.
Dr Yi Nie mentioned that the use of simulation technology effectively previews the forming mechanism under extreme and complex environments through virtual modelling, which significantly reduces the debugging requirements for physical printing and industrial production costs. The design of structural materials, on the other hand, breaks through the limitations of traditional solid structures and optimises damping, noise reduction and heat dissipation performance. In addition, Dr Yi Nie is using the simulation model to further optimise 3D printing formulations to enhance the efficiency of industrial applications and help the innovative development of new productive force.
Innovation in the Waste-Free city: Hydrogen from waste and waste control by waste
Hydrogen is recognised as a crucial element in facilitating the global energy transition, serving as a renewable energy source that can substitute for fossil fuels. Dr Ibrahim Khan, as the Assistant Professor in Renewable Energy and Energy Storage at the China Beacons Institute and one of the “World’s Top 2% Scientists”, presented his research on hydrogen production from waste during the event. Dr Ibrahim Khan said, “Conventional methods of hydrogen production, such as electrochemical and thermal splitting, are expensive and energy-intensive, which to some extent restricts their industrial applications.”
To address this challenge, his research has centred on utilisation of wastes such as biomass (particularly food wastes) to develop highly durable and novel carbon-based electro-photocatalysts to transform water and plastics into more useful products such as green hydrogen and low molecular weight chemicals by water splitting and photoreforming techniques. These processes allow for the efficient utilisation of cheaper and abundantly available feedstocks such as water and biowastes, and also considerably contribute to carbon neutrality and environmental sustainability through a zero-emission hydrogen fuel production.
“In particular, photoreforming technology holds the advantage of decentralised production. By directly extracting hydrogen from local waste, this technology effectively eliminates the additional costs associated with long-distance transportation and extensive infrastructure development,” Dr Ibrahim Khan explained.
Dr Fathima Jerosha Ifthikar Ahmed, who worked on waste resourcing, shared her views on turning municipal waste into value. She explained: “We try to convert such municipal wastes like sludge, food waste, wood waste and other wastes commonly found in cities into valuable materials like adsorbents and catalysts. These materials show great potential in removing heavy metal ions, antibiotics and other emerging pollutants from wastewater.”
It is understood that this research, which is now being tested in pilot plants, has been validated for its practicality and cost-effectiveness, and is expected to provide new ideas for the resourceful use of municipal waste. In addition, with the rapid growth of electronic waste, Dr Fathima Jerosha Ifthikar Ahmed has also extended her research into this area, actively exploring ways to resource this type of electronic waste to promote the development of a circular economy.
Intelligent innovation in medical field: new smart sensing dressing
Amidst the wave of intelligent upgrades and innovations in the global healthcare industry, Dr Sze Shin Low, Assistant Professor in Life Science and Healthcare at the China Beacons Institute and one of “the World's Top 2% Scientists”, has developed a smart sensing system in order to proactively address the health challenges posed by chronic diseases.
Dr Sze Shin Low explained, “The new Janus membrane dressing developed in our lab breaks the limitations of traditional dressings by improving antimicrobial properties and wound exudate management. What's more, it incorporates a smart sensing system with a chip housed in the dressing that can be connected to a smart device for real-time, continuous and precise wound monitoring.”
This innovation not only greatly improves patients' quality of life and treatment experience, but also provides medical workers with a more convenient and efficient tool for analysing patients’ conditions, helping them to make more accurate decisions.
Greater Bay Area Science Forum came to a successful end on 18th November. Looking ahead, the China Beacons Institute will continue to take advantage of the excellent academic network and scientific research resource of the UNNC, focusing on scientific and technological innovation with a global vision and empowering industrial transformation and upgrading.
