Nobel Laureate Professor Sir Andre Geim takes HKU on a “Random Walk to Graphene” in inaugural lecture

The University of Hong Kong
Meeting Announcement

Professor Sir Andre Geim, Nobel Laureate and Chair Professor in the Department of Physics under the Faculty of Science at the University of Hong Kong (HKU), delivered his inaugural lecture titled "Random Walk to Graphene" on 9 June. Held at the Grand Hall of the Lee Shau Kee Lecture Centre, the lecture delved into how simple curiosity—and a willingness to embrace the unexpected—led to one of the most groundbreaking discoveries of our time. The event drew an audience of about 800 participants, spanning academic, policy, practitioner and student communities.

HKU chemists unlock the secret to designing ultra-tough and responsive “smart” materials

A research team led by Professor Yufeng WANG and Professor Ho Yu AU-YEUNG from the Department of Chemistry at The University of Hong Kong (HKU) has achieved a breakthrough to address this challenge. By using discrete molecular rings as precise structural models of polymer knots, the team untangled the complex relationship between molecular architecture and material properties, allowing them to correlate characteristics such as stiffness, strength, and elasticity with the specific structures and topologies of the molecular rings. Their findings were recently published in the prestigious Journal of the American Chemical Society (JACS).

Professor YAO Wang, Chair Professor in the Department of Physics at The University of Hong Kong (HKU), has received a Certificate of Merit at the Fourth National Award for Excellence in Innovation in recognition of his outstanding contributions to valley optoelectronics in two-dimensional semiconductors.

First physics result of Jiangmen Underground Neutrino Observatory published in Nature

Chinese Academy of Sciences Headquarters
Peer-Reviewed Publication

JUNO's first physics result was published in Nature. Through the analysis of valid data collected over 59 days from August 26 to November 2, 2025, the JUNO Collaboration made the high-precision measurement of the two key oscillation parameters, reducing the associated uncertainties by a factor of 1.6 compared to the combined experimental results in the past decades.

A fentanyl countermeasure that adapts to combat future black-market drugs

Scripps Research Institute
Peer-Reviewed Publication

Fentanyl and related variants of the synthetic opioid kill more Americans each year than car accidents and gun violence combined. In too-high doses, the drugs hijack brain chemistry and shut down the signals that control breathing. Existing medical interventions can reverse an overdose, but only if given quickly enough after it occurs. Now, scientists at Scripps Research have shown the feasibility of a completely different approach to combating fentanyl deaths: a vaccine that teaches the immune system to rapidly neutralize the drug before it reaches the brain in the first place.

Biochar’s hidden electron power could unlock cleaner pollution control and energy recovery

Biochar Editorial Office, Shenyang Agricultural University
Peer-Reviewed Publication

Biochar has often been praised as a “black gold” for sustainable agriculture, pollution control, and carbon storage. Yet despite its promise, its wider use has been limited by a practical challenge: compared with materials such as activated carbon, graphene, and carbon nanotubes, biochar often has lower surface area and electrical conductivity. Expensive post-treatment methods can improve its performance, but they may also increase cost, energy use, and secondary pollution.

Fungi help biochar and compost lock more carbon in nutrient-poor urban soils

Biochar Editorial Office, Shenyang Agricultural University
Peer-Reviewed Publication

Urban parks, campus lawns, residential gardens, and other greenspaces are vital parts of city life. They cool neighborhoods, support biodiversity, store carbon, and provide places for people to relax. Yet many urban soils are losing organic matter and nutrients under the pressure of rapid urbanization. A new study published in Biochar suggests that the success of common soil restoration practices may depend strongly on one often-overlooked factor: the balance between fungi and bacteria already living in the soil.

New paper shows overlooked pollutants are responsible for about 15% of current global warming

Spark Climate Solutions
Peer-Reviewed Publication

A new paper by leading climate scientists and policy experts finds that indirect greenhouse gases account for roughly 15% of current global warming from human emissions yet remain largely absent from climate policy. These overlooked pollutants, including carbon monoxide, non-methane volatile organic compounds, nitrogen oxides, and molecular hydrogen, do not warm the climate directly. Instead, they alter atmospheric chemistry in ways that increase levels of methane, ozone, and other greenhouse gases, which results in increased warming. Reducing these emissions represents an overlooked opportunity to slow warming while delivering air quality benefits.
