3D Printed Triply Periodic Minimal Surface (TPMS) Bone Scaffolds

Principle Investigator: 
Dr Xin ZHAO, Associate Professor, Department of Applied Biology and Chemical Technology; Founder, ReNew Biotechnology Limited (a PolyU academic-led start-up) 

Triply Periodic Minimal Surface (TPMS) scaffolds mimicking trabecular bone are 3D printed with hyperboloidal topography using β-tricalcium phosphate. The TPMS scaffolds show high porosity and interconnectivity, which can reduce stress concentration for increased mechanical strength. They can also support the adhesion and proliferation of human mesenchymal stem cells (hMSCs) and enhance their osteoblastic differentiation and angiogenic paracrine for “osteogenesis-angiogenesis coupling”. This is achieved by reorganising cytoskeleton via hyperboloidal topography with focal adhesion kinase (FAK) and mitogen activated protein kinase (MAPK) pathway activation. The in vivo evaluation further demonstrates that our TPMS scaffolds boost enhanced new bone formation and neovascularisation. In summary, our scaffolds provide a purely physical way to guide the osteogenic and angiogenic cell fates, and demonstrate drastic but quantifiable improvements in bone regeneration without introducing exogenous factors. We believe that these features offer our scaffolds a head start towards a simple, safe, efficient, and personalised bone graft with tremendous clinical potential.

Autophagy-targeting Peptidomimetics as Novel Cancer Therapeutics

Principle Investigator:
Prof. Yanxiang ZHAO, Associate Head, Departmental Learning and Teaching Committee Chair and Professor, Department of Applied Biology and Chemical Technology

Autophagy is an evolutionarily conserved self-degradative process that turns over intracellular components in a lysosome-dependent manner. Autophagy has long been regarded as a key factor in cancer formation and development. We have developed chemically modified molecules called peptidomimetics that target the autophagy process and inhibit cancer cell proliferation.

We have validated this approach in multiple animal models. The peptidomimetics have good anti-tumour efficacy in multiple cancers, especially those that have no effective therapies, such as triple-negative breast cancer and pancreatic cancer. The hydrocarbon stapling of the peptidomimetics also allows them to have high stability. Meanwhile, our peptidomimetics have a clear target, the critical autophagy regulator, Beclin 1. By binding to Beclin1 with high affinity, the peptidomimetics can regulate autophagy and mediate the related cell signalling pathways in cancer biogenesis and development. The high selectivity of our peptidomimetics means that they have a good safety record in animals. This indicates that they have the potential to be an effective strategy for malignant cancers.

A Fireproof Solar PV Vacuum-Glazing Wall Panel (FSVG) as Building Insulation Layer

Principle Investigator:
Ir Prof. Hongxing YANG, Professor, Department of Building Environment and Energy Engineering

Fire emergencies on building facades have dramatically increased in recent years. The main culprit is combustible external wall insulation, which can ignite and spread rapidly due to the chimney effect of high-rise buildings. Several cities – among them London, Shanghai, and Tianjin – have experienced tragic accidents involving this material, resulting in deaths, injuries, and property damage.

This novel Fireproof Solar PV Vacuum-Glazing (FSVG) wall panel addresses this challenge. It is a non-combustible and highly thermal insulation material that combines superior thermal insulation, soundproofing, and power generation to help create low-carbon buildings. In Hong Kong, FSVG wall panels can replace traditional curtain walls while also generating solar power, reducing the cooling load of buildings by 57% and generating 170 kWh/m2 of electricity every year.

The invention is especially suitable for areas with cold winters, such as Shanghai and Beijing, where external wall insulation is necessary. It can save a large amount of energy without posing any fire hazard.

FRP-ECC-HSC Composite Column

Principle Investigators:
Prof. Tak-ming CHAN, Professor, Department of Civil and Environmental Engineering
Dr Shuai LI, Postdoctoral Fellow, Department of Civil and Environmental Engineering
Ir Prof. Ben YOUNG, Vice President (Student and Global Affairs) & Chair Professor of Steel Structures, Department of Civil and Environmental Engineering

The FRP-ECC-HSC composite column is a novel structural column consisting of three layers: an outer Fibre-Reinforced Polymer (FRP) tube, a middle Engineered Cementitious Composite (ECC) ring, and an inner High Strength Concrete (HSC) core. Unlike conventional FRP-confined HSC columns, which may crack locally and fail prematurely due to the high brittleness of HSC, this column uses the ECC ring, which has excellent tensile and cracking behaviour, to redistribute the hoop stress and strain from the HSC core to the FRP tube. This results in a more uniform lateral confinement, a larger FRP confining efficiency, as well as a higher column deformability than conventional FRP-confined HSC columns. The FRP-ECC-HSC composite column has excellent compressive behaviour with both high loading capacity and high ductility. It has great potential for use in infrastructure in marine environments and coastal areas.

Multi-Functional High-Power-Density Integrated Onboard Charger for Electric Vehicles

Dr Ka-hong LOO, Associate Professor, Department of Electrical and Electronic Engineering; Assistant Dean (External Engagement), Faculty of Engineering
Dr Junwei LIU, Research Assistant Professor, Department of Electrical and Electronic Engineering

Electric vehicles are usually charged using conductive (plug-in) charging. However, wireless charging is becoming more popular and has many advantages. Future electric vehicles are expected to have both conductive and wireless chargers. Very few solutions currently combine both types of chargers. Those that do have disadvantages such as a large number of components, an inefficient conductive charger, or a slow charging time because it is not possible to energise both chargers at the same time.

This new multi-functional integrated on-board charger (IOBC) overcomes these problems by offering both conductive and wireless charging in one compact design. By sharing the pickup coil of the wireless charger with the conductive charger, the IOBC does not need additional components and can control both chargers independently. This achieves efficient, simultaneous power transfer with minimal components, volume, and cost.

Invention and Application of Vitamin D Supplement Preparations

Principle Investigator: 
Prof. Man-sau WONG, Director, Research Centre for Chinese Medicine Innovation; Professor, Department of Food Science and Nutrition

This invention involves a novel vitamin D supplement preparation and its application. The vitamin D supplement contains two active ingredients: calcitriol and oleanolic acid. Oleanolic acid is a natural product that boosts the activity of CYP27B1 (a vitamin D3 bioactivation enzyme) at low concentrations in bone marrow stromal cells and osteoblasts, thereby enhancing the synthesis of bioactive vitamin D3 (1,25(OH)2D3) and promoting osteogenesis. The invention uses an oily mixture formulation of low-concentration oleanolic acid and 25(OH)D3, which is more effective in promoting osteoblast differentiation than using either ingredient alone. The oily mixture also increases the bioavailability of oleanolic acid, significantly reducing the amount needed and alleviating the toxic effects of high-dose oral administration of the natural product on tissues and cells. This vitamin D supplement preparation can be used to prevent and treat bone diseases caused by vitamin D deficiency.
