Computational Fluid Dynamics (CFD) is a pivotal tool in modern engineering and scientific research. As simulation scale increases, computational acceleration for CFD have become a prominent focus. The implicit-explicit (IMEX) method partitions spatial regions to apply implicit or explicit methods, maintaining numerical stability while enhancing computational efficiency. Numerical results demonstrate that IMEX methods achieve efficiency improvements exceeding an order of magnitude compared to classical methods. In the future, coupling IMEX methods with GPU architectures will achieve greater computational speedups in extreme-scale simulations.

The rotating stall precursor is a major research focus in the field of aerodynamic compressor flow stability, as an accurate understanding of its physical mechanisms can help improve the operating margin of the compressor system in aircraft engines and ensure flight safety. With advances in numerical simulation techniques, the physical essence of spike-type stall has been increasingly investigated in depth. Many studies assume that weak-amplitude disturbances exist prior to stall and facilitate its onset; however, the specific nature of these disturbances, their relationship with the spontaneous unsteady behavior of the flow, and whether these disturbances serve as the origin of the spike-type stall, have yet to be clarified.

Laura Cancedda, head of the Brain Development and Disease Research Unit at the Italian Institute of Technology (Istituto Italiano di Tecnologia – IIT), has today been elected a member of the European Molecular Biology Organization (EMBO), the international community of more than 2,100 distinguished scientists in the life sciences field across Europe and around the world. Receiving EMBO Membership is a recognition of the excellence of her research and the outstanding achievements throughout her career.

Researchers from Ningbo University and The University of Hong Kong have proposed a novel 3D nanoprinting technique to fabricate high-resolution piezoceramic structures. This method enables precise control over PZT nanostructures with high elasticity and exceptional piezoelectric performance. Their breakthrough allows the creation of flexible, ultra-sensitive sensors, including a bionic air-flow sensor capable of detecting airflow as low as 0.02 m·s⁻¹—nearly 10 times more sensitive than conventional designs.

This innovation paves the way for next-generation piezoelectric devices in industrial sensing, biomedical implants, and IoT applications, offering a scalable and efficient approach to high-performance nanomanufacturing.

The scientific team of Dr. Miloslav Polášek at IOCB Prague has developed a new method of separating the rare earth elements, or lanthanides, which are widely used in the electronic, medical, automotive, and defense industries. The unique method allows metals such as neodymium or dysprosium to be purified from used neodymium magnets. The environmentally friendly process precipitates the rare earths from water without organic solvents or toxic substances. The results were published in the Journal of the American Chemical Society (JACS) at the end of June.
