Magnetic skyrmions are particle-like objects that can be used as information carriers in memory and computing devices. Researchers from Waseda University recently studied the flow behaviors of many skyrmions in structured magnets and found that skyrmions can behave like chiral fluids. They proposed that fully developed skyrmion flows can be used for fluidics, which significantly reduces complexity of skyrmion logic, as it eliminates the need for deterministic creation, precise control, and detection of individual skyrmions.

Silicon, aluminium and lithium are the most critical raw materials on the planet. Their scarcity and the complexity of extracting them could hinder the development of technologies that are key to the green transition. This is one of the main conclusions of a study by the INGENIO Institute, a joint centre of the Spanish National Research Council (CSIC) and the Universitat Politècnica de València (UPV), in collaboration with the University of Rome, the Universitat de València and the University of London.

The University of Liverpool has unveiled an ambitious plan for a new £100 million AI Materials Hub for Innovation (AIM-HI) dedicated to accelerating the application of artificial intelligence in materials chemistry. 

Scientists have delivered the most detailed assessment yet of a set of disputed lead books known as the Jordan codices. With debate centred on whether they could date back to the early Christian period, a study led by the University of Surrey’s Ion Beam Centre has now shed new light on their origin. 

A team led by Prof. ZHOU Yongjin from the Dalian Institute of Chemical Physics demonstrated that combining lifespan engineering strategies with metabolic pathway optimization in Saccharomyces cerevisiae enables highly efficient sclareol biosynthesis, marking an advance in improving microbial production through lifespan engineering.

A research team led by Associate Professor Yukihide Ishibashi at the Graduate School of Science and  Engineering, Ehime University, has successfully achieved the direct observation of exciton diffusion processes within individual copper phthalocyanine（CuPc）nanofibers using a custom-built femtosecond microspectroscopy technique, which enables clarification of exciton dynamics in mesoscopic materials. Previously, only ensemble-averaged information（e.g., CuPc thin films）was available for exciton diffusion coefficients and diffusion lengths. By measuring these parameters for single nanofibers, the team revealed that the diffusion coefficient of η-phase CuPc nanofibers is about three times higher than that of β-phase ones. This enhancement arises from the larger molecular tilt angle and stronger π–π overlap in the η-phase, which promote intermolecular excitonic interactions. Moreover, the diffusion coefficient was found to decrease with increasing fiber length, indicating a “size effect” in exciton hoopping. This study not only deepens the understanding of optical properties in organic molecular crystals but also provides important insights for improving the efficiency of organic photovoltaic and photoenergy-conversion devices. The findings were published online in The Journal of Physical Chemistry Letters by the American Chemical Society on October 31, 2025.
