A computational method combining generative AI with atomistic simulations can identify promising platinum alloy catalyst structures for hydrogen fuel cells, report researchers from Science Tokyo. Their approach addresses a longstanding challenge in catalyst design and consistently produces high-performing candidates from several material combinations.

Although solid-state batteries (SSBs) demonstrate high performance and are intrinsically safe, their capacity currently declines rapidly. A team from the TU Wien, Humboldt-University Berlin and HZB has now analysed a TiS₂|Li₃YCl₆ solid-state half-cell in operando at BESSY II using a special sample environment that allows for non-destructive investigation under real operating conditions. Data obtained by combination of soft and hard X-ray photoelectron spectroscopy (XPS and HAXPES) revealed a new degradation mechanism that had not previously been identified in solid-state batteries. They have gained some surprising insights, particularly regarding the harmful role played by intrinsic oxygen. This study provides valuable information for improving design and handling of such batteries.

A core-shell Pd@CeO₂/γ-Al₂O₃ catalyst improves exhaust treatment for stoichiometric natural gas vehicles by promoting lower-temperature CH₄ and NO conversion and strong hydrothermal stability. The design lowers reaction barriers at Pd-CeO₂ interfaces and retains high activity after severe aging. After aging at 800 °C for 16 hours, the catalyst showed only minor losses in CH₄ and NO conversion over a 100-hour test, offering a promising route to cleaner and more durable NGV aftertreatment.

As competition among the world’s leading ports intensifies, ports must become not only bigger and faster, but also smarter, more resilient and more sustainable. Singapore’s ability to stay ahead depends on how well it plans, models and optimises increasingly complex port systems. At the Centre of Excellence in Modelling and Simulation for Next Generation Ports (C4NGP) at the College of Design and Engineering at NUS research in digital twins, simulation and decision-support tools is helping shape the future of Singapore’s port ecosystem. Working closely with government agencies and industry partners, C4NGP supports evidence-based planning across port design, operations, resilience and sustainability, contributing to initiatives such as Singapore’s Maritime Digital Twin and long-term low-carbon port development. Learn how research and innovation are helping prepare Singapore’s ports for the future.

A team of researchers from the North China Electric Power University and the National Institute of Metrology in China has published a perspective on a promising class of materials for extracting uranium from aqueous environments. Their work details the design and application of heterocyclic-linked covalent organic frameworks (COFs), which use light to perform this critical task. This approach holds significant potential for both cleaning up contaminated water sources and securing a sustainable supply of uranium, the primary fuel for nuclear energy, by extracting it from seawater.

The dual need for environmental remediation and resource security has spurred the development of new technologies for uranium capture. Traditional methods face challenges with selectivity and capacity. The authors explain that photocatalysis offers a distinct advantage by using light to trigger specific redox reactions, reducing soluble and mobile uranium (U(VI)) into insoluble and immobile forms (U(IV)). The success of this technique depends on creating highly efficient photocatalysts. The focus of this perspective is on COFs, which are crystalline, porous materials built from organic molecules linked by strong covalent bonds.
