# 1. Neuroscience: Alzheimer's Disease Research and the State Key Laboratory

# 1.1 The Nancy Ip Team and the IL-33 Discovery (2016)

Nancy Ip (Yip Yuk-yu) joined HKUST in 1993 and has since devoted her career to the biology of neurotrophic factors, concentrating on neural development and function as well as drug discovery for neurodegenerative diseases such as Alzheimer's. Her team discovered that the body's own protein interleukin-33 (IL-33, 白細胞介素-33) can significantly ameliorate cognitive decline and Alzheimer's-like pathology^※, providing an important molecular basis for potential therapeutic targets.

# 1.2 Two Blood-Test Breakthroughs (2021, 2024)

In 2021 an HKUST research team announced the development of a simple blood test^※ capable of identifying Alzheimer's risk before symptoms appear, overcoming the previous reliance on costly imaging or invasive spinal fluid collection. In 2024 an international team led by Nancy Ip formally published its findings in Alzheimer's & Dementia: The Journal of the Alzheimer's Association^※, reporting a blood test that simultaneously measures 21 proteins and is applicable across different ethnic groups. Key figures: diagnostic accuracy for Alzheimer's disease exceeded 96%^※, while the detection rate for mild cognitive impairment (MCI) was approximately 87%^※; international collaborators included University College London (UCL) and the Barcelona βeta Brain Research Center. Distinguished by its parallel analysis of multiple biomarkers rather than a single indicator, the test has been licensed to the start-up Cognitact Limited for commercial diagnostic services.

# 1.3 The State Key Laboratory of Nervous System Diseases and HKCeND

Two institutional pillars underpin HKUST's neuroscience research: the State Key Laboratory of Nervous System Diseases (formerly the State Key Laboratory of Molecular Neuroscience, approved in 2009 and restructured and renamed in February 2025^※; see State Key Labs and Research Institutes (Part 1)^※); and the Hong Kong Center for Neurodegenerative Diseases (HKCeND) — established in 2020 with HK$500 million in funding from the HKSAR Government under the InnoHK initiative^※, directed by Nancy Ip. The centre aims to become a world-leading institution for neurodegenerative disease research and knowledge transfer, bringing together over 60 researchers who have developed gene-therapy strategies targeting Alzheimer's. On 1 July 2022, during his visit to Hong Kong, President Xi Jinping toured the centre at Hong Kong Science Park^※, where he was briefed on advances in the Alzheimer's blood test and stem-cell research.

A summary of Nancy Ip's academic honours: According to her official HKUST profile, Nancy Ip has published more than 334 scientific papers and holds 70 patents^※. She has been elected an academician of the Chinese Academy of Sciences, a Foreign Associate of the US National Academy of Sciences, a member of the American Academy of Arts and Sciences, and a fellow of The World Academy of Sciences. She has received the State Natural Science Award, the UNESCO-L'Oréal For Women in Science Award, and was named one of Nature's "10 Science Stars of China" (for a full list of academy memberships and awards see State Key Labs and Research Institutes (Part 2)^※).

In 2011 Tang received the Wolf Prize in Chemistry^※, becoming the first Chinese scientist to win the award. He joined the HKUST Jockey Club Institute for Advanced Study (IAS) in 2013 as the IAS Bank of East Asia Professor^※ and was awarded the 2019 Kyoto Prize in Advanced Technology^※.

In 2013 HKUST received approval to establish the State Key Laboratory of Advanced Displays and Optoelectronics Technologies^※ (a partnership with Sun Yat-sen University), focusing on oxide thin-film transistor (TFT) arrays, third-generation OLED devices, and liquid-crystal display (LCD) technology (for its history see State Key Labs and Research Institutes (Part 1)^※).

# 2.2 The Materials Research Ecosystem and the William Mong Institute of Nano Science and Technology

Materials research at HKUST spans fundamental wave-functional materials, nanotechnology (nano-optics, advanced nanocomposites, nano-electronic devices, smart nanomaterials), graphene and two-dimensional materials (energy storage, biosensing, aerogels), and many other broad directions^※. In 2025 the journal Advanced Materials published a special retrospective reviewing HKUST's 35-year trajectory of materials research innovation^※, recognising the University's sustained leadership in the field.

The William Mong Institute of Nano Science and Technology (WMINST) was founded in 2001 as the Institute of Nano Science and Technology and renamed on 1 February 2008^※. Its founding director, Professor Shen Ping, was one of the key scholars behind HKUST's landmark achievement of fabricating the world's smallest carbon nanotube (2000, measuring just 0.4 nanometres in diameter; see HKUST "Firsts" and Major Achievement Lore^※). The Institute stands in a "micro–macro" contrast with the big-picture perspective of the GREAT Smart Cities Institute; for a detailed institutional history see The Interdisciplinary Research Institute Cluster^※.

# 2.3 Successive Breakthroughs in Perovskite Optoelectronic Materials

HKUST has made several significant advances in perovskite solar cells in recent years, tracing a clear technological evolution:

• 2024: A research team published findings in Science^※ reporting the construction of the world's first chiral-structured "spring-like" interface, substantially enhancing both the reliability and photoelectric conversion efficiency of perovskite solar cells. After encapsulation, the cells retained 92% of their initial efficiency after 1,200 hours of testing over a temperature range of −40°C to 85°C.
• 2026: A team led by Professor Lin Yen-Hung of the Department of Electronic and Computer Engineering employed a lead-chloride "co-evaporation" multi-source vapour-deposition technique to precisely control crystal-plane orientation, achieving the world's first certified fully vacuum-deposited wide-bandgap perovskite solar cell, with a certified conversion efficiency of 18.35%^※. The work was published in Nature Materials, with collaborators including Professor Henry Snaith's group at the University of Oxford. When combined with silicon in a tandem cell, the efficiency reached 27.2%, with 80% of initial performance retained after eight months of outdoor operation.
• In addition, the team developed a lead-free, lightweight, low-cost perovskite photo-rechargeable lithium-ion battery (photo-battery)^※ that integrates solar-energy harvesting and energy storage in a single device.
