Researchers at the University of Natural Resources and Life Sciences, Vienna, and Institut Teknologi Sumatera, Indonesia, set out to explore the dynamics behind shared micromobility fleet development. By utilizing a system dynamics modeling approach, they examined how fleet size, user demand, regulatory policies, and economic factors interact to shape the success of these systems.

A recent study unveils an innovative composite phase change material (CPCM) tailored for lithium-ion battery (LIB) thermal management. Using hydrated salts, this material is engineered to regulate battery temperatures and mitigate thermal runaway (TR) risks, paving the way for safer and more efficient battery applications. The research emphasizes the dual benefits of improved energy densities and longevity while addressing pressing safety concerns associated with high-rate charging and discharging.

In a study published in Science China Earth Sciences, research teams from China collaboratively reconstructed the tectonic evolution and sedimentary filling processes of the North Sea Basin through the lens of multi-spheric interactions. Their analysis reveals how deep dynamic processes, climate, and transgression evolution jointly controlled the formation and development of distinct gas-rich and oil-rich zones in the basin, while also discusses hydrocarbon exploration prospects in mid- to high-latitude regions.

Researchers from Qingdao University and the Qingdao Institute of Bioenergy and Bioprocess Technology (QIBEBT) of the Chinese Academy of Sciences have developed a novel method for rapidly and accurately assessing the metastatic potential of cancer cells. The new tool— combining Raman spectroscopy and machine learning—introduces the Ramanome-based Metastasis Index (RMI), offering an innovative means of diagnosing and managing cancer.

In a review published in SCIENCE CHINA Chemistry, the phase and phase transition regulation of bismuth-based semiconductors (BBSs) were systematically presented based on the classification of BBSs. Notably, the critical factors for phase transition of BBSs, and intrinsic driving forces endowed by phases of BBSs for enhanced photocatalytic performances of organic contaminants removal were also elucidated.

Recently, a research team from Jilin University and Hainan University reported a jointed experimental and theoretical study on Coulomb focusing in energy-resolved angular streaking. It was found that photoelectrons emitted at different initial ionization times can converge to the same emission angle due to previously unexpected Coulomb focusing in nonadiabatic tunneling. The findings have significant implications for decoding quantum tunneling dynamics under the classically forbidden barrier with attosecond angular streaking.
