Professor Zhongkui Zhao of Dalian University of Technology, in collaboration with Professor Riguang Zhang of Taiyuan University of Technology, Researcher Yuefeng Liu of the Dalian Institute of Chemical Physics, Chinese Academy of Sciences, Professor Ting Zhang of Qingdao University, and Professor Chunshan Song  of the Chinese University of Hong Kong, constructed a single-atom Cu-N₂O₁ site with axial oxygen coordination on C₃N₄. Through the polar activation of the CH bond by the polar Cu-O bond, they successfully pioneered a new photocatalytic methane upgrading strategy independent of reactive oxygen species. This strategy not only significantly increased the rate of photocatalytic methane conversion to ethanol by 226  μmol/g/h under mild conditions, but also achieved an ethanol product selectivity as high as 98%. This achievement not only greatly advances the basic understanding of photocatalytic methane conversion to ethanol, but also creates a new paradigm for photocatalytic methane upgrading, successfully solving the seesaw dilemma between the liquid fuel generation rate and its selectivity in the photocatalytic methane conversion process, and providing new ideas and methods for the innovative development of future photocatalytic methane conversion. The article was published as an open access research article in CCS Chemistry, the flagship journal of the Chinese Chemical Society.

A Georgia Tech-led team reveals how diatoms' rapid transformations are reshaping our understanding of how ocean sediments regulate carbon and climate.

Can you imagine a future where insulin releases itself—without sensors or human intervention?

Researchers at ESPOL have developed an advanced mathematical model that simulates a device capable of doing just that. Based on glucose sensitive hydrogels, this system could revolutionize diabetes treatment, offering a more autonomous, safe, and biocompatible approach.

The inherent directionality of speakers and complex shapes of car cabins can exacerbate sound disparities between the drivers and passengers, no matter how advanced a speaker system. In the Journal of Applied Physics, researchers create a prototype using a fractal to mitigate the sound differences. To create their metamaterial, they used precise molding to shape the fractal and then placed it over a car speaker. They measured the sound pressure levels at different seats in the car and found their disparity significantly decreased, including at higher frequencies.

SAN ANTONIO — November 11, 2025 — Southwest Research Institute (SwRI) has expanded the capabilities of its world-class Metering Research Facility (MRF) to ensure existing natural gas infrastructure is compatible with hydrogen fuels. This initiative is supported by internal funding and combines SwRI’s expertise in energy, power, and automotive engineering to help several industries evaluate how blending hydrogen with natural gas affects infrastructure and technology.
