Ultrasound unlocks a safer, greener way to make hydrogels
McGill UniversityPeer-Reviewed Publication
Researchers at McGill University, in collaboration with Polytechnique Montréal, pioneered a new way to create hydrogels using ultrasound, eliminating the need for toxic chemical initiators. This breakthrough offers a faster, cleaner and more sustainable approach to hydrogel fabrication, and produces hydrogels that are stronger, more flexible and highly resistant to freezing and dehydration. The new method also promises to facilitate advances in tissue engineering, bioadhesives and 3D bioprinting.

Self-assembly of a large metal-peptide capsid nanostructure through geometric control
Institute of Science TokyoPeer-Reviewed Publication
A significant advancement in molecular engineering has produced a large, hollow spherical shell nanostructure through the self-assembly of peptides and metal ions, report researchers from Japan. This dodecahedral link structure, measuring 6.3 nanometers in diameter, was achieved by combining geometric principles derived from knot theory and graph theory with peptide engineering. The resulting structure demonstrates remarkable stability while featuring a large inner cavity suitable for encapsulating macromolecules, opening pathways for producing complex artificial virus capsids.

A smarter way to make sulfones: Using molecular oxygen and a functional catalyst
Institute of Science TokyoPeer-Reviewed Publication
As a recent leap in green chemistry, scientists from Japan have unveiled a new catalyst that enables high yields of sulfones using molecular oxygen—close to room temperature. By fine-tuning the structure of oxygen vacancies in perovskite oxide catalysts, the researchers successfully reduced the reaction temperature from 80–150°C to nearly 30°C, offering improved energy efficiency. The study marks a significant milestone in advancing complex sulfide oxidation reactions, offering sustainability with excellent efficiency.

German satellite measures CO2 and NO2 simultaneously from power plant emissions for the first time
Max Planck Institute for ChemistryPeer-Reviewed Publication
A research team from the Max Planck Institute for Chemistry in Mainz and Heidelberg University has, for the first time, used the German environmental satellite EnMAP (Environmental Mapping and Analysis Program) to simultaneously detect the two key air pollutants carbon dioxide (CO₂) and nitrogen dioxide (NO₂) in emission plumes from power plants – with an unprecedented spatial resolution of just 30 meters. The newly developed method allows for tracking of industrial emissions from space with great precision and enables atmospheric processes to be analyzed in detail. The results were published in the journal Environmental Research Letters.

Is air pollution exposure equal across South Korea?
Pohang University of Science & Technology (POSTECH)Peer-Reviewed Publication
A research team led by POSTECH Professor Hyung Joo Lee found that NO2 exposure levels were consistently higher in areas with higher socioeconomic status—an outcome shaped by South Korea’s distinctive history of rapid economic development and urban planning.
