Researchers at the Hong Kong University of Science and Technology (HKUST) have developed a new integration technique for efficient integration of III-V compound semiconductor devices and silicon, paving the way for photonic integration at low cost, large volume, and high speed and throughput that could revolutionize data communications. Unlike conventional integrated circuits, or microchips, that use electrons, photonic integrated circuits use photons, or particles of light. Photonic integration combines light and electronics to speed up data transfer. Silicon photonics (Si-photonics), in particular, is at the forefront of this revolution as it enables the creation of high-speed, low-cost connections that can handle massive amounts of data at once.

An international research team led by the Hong Kong University of Science and Technology (HKUST) has achieved a significant breakthrough by developing an artificial intelligence (AI) model that can help mitigate global ammonia (NH3) emission from agriculture.   Harnessing the power of machine learning, this groundbreaking study not only revealed that global NH3 emissions from cropland are lower than previously estimated, but also demonstrated how optimizing fertilizer management can effectively reduce emissions by approximately 38%, without compromising the overall use of nitrogen fertilizers. It provides valuable insights for policymakers worldwide to address the United Nations' Sustainable Development Goals related to poverty eradication, food security, and sustainable agriculture.

Researchers from The Hong Kong University of Science and Technology (HKUST) have developed a sensor array design technology inspired by the human auditory system. By mimicking the human ear's ability to distinguish sounds through tonotopy, this innovative sensor array approach could optimize the application of sensor arrays in fields such as robotics, aviation, healthcare, and industrial machinery. Traditional sensor arrays face challenges such as complex wiring, limited reconfigurability, and low damage resistance. The design developed by the HKUST team, led by Associate Professor YANG Zhengbao from the Department of Mechanical & Aerospace Engineering, addresses these challenges by assigning a unique frequency to each sensor unit and using the sensor unit signal to modulate the amplitude of the frequency signal, similar to the distinct frequencies processed by hair cells in the human cochlea.

Hong Kong University of Science and Technology (HKUST) has jointly established a laboratory with Absolute Pure EnviroSci Limited (APEL) to develop and translate novel discoveries into groundbreaking health and environmental innovations.  These include highly effective and long-lasting pest repellent against bedbugs that can also inactivate up to 99.9 percent of highly-infectious viruses, bacteria and hard-to-kill spores, as well as artificial organoids that could help quantify pollution’s risks on human health and provide essential data for establishing a health monitoring system in Hong Kong and Greater Bay Area (GBA).

A research team led by The Hong Kong University of Science and Technology (HKUST) has developed an optical plasmonic tweezer-controlled Surface-Enhanced Raman Spectroscopy (SERS) platform that utilizes on-and-off control of light to probe various amylin species in mixtures at the single-molecule level, unveiling the hetergogerous structures of pH-dependent amylin species, and the secrets behind amyloid aggregation mechanisms associated with type 2 diabetes.

A research team at HKUST has outlined the high-resolution structure of a little-known virus, improving our understanding of viral infection, which could pave the way for more accurate predictions of climate change.

The Hong Kong University of Science and Technology (HKUST) and Tsinghua University jointly launched the ‘International AI Cooperation and Governance Forum 2023’ today. The two-day forum brings together over 50 world-renowned artificial intelligence (AI) experts, scholars, industry leaders, government representatives and international organization delegates to explore the opportunities and challenges brought by cutting-edge technologies such as generative AI, and discuss strategies for building a comprehensive global governance framework for the new technology.
