In this study, the controllable synthesis of highly stable Ag₅₆ clusters was achieved using 4-vinylbenzoic acid (abbreviated as p-VBA) and tert-butyl mercaptan as ligands by precisely regulating reaction parameters such as temperature and solvent. Furthermore, the intermediates Ag₂₀, Ag₃₁, Ag₃₂ and the dimers of the intermediate Ag₃₁/Ag₃₂, Ag₃₀-bpbenz (bpbenz, 1,4-di(4-pyridyl)benzene) and Ag₃₁-bpe (bpe, 1,2-bis(4-pyridyl)) were successfully captured. This series of nanoclusters exhibited a unique fluorescence aggregation-induced redshift phenomenon as the π–π interaction of the ligand. In addition, the Ag₅₆ nanocluster can be used as near infrared fluorescence sensors for Br⁻/I⁻ and their detection limits were as low as 85 and 105 nM, respectively. The results of this study provide new ideas and methods for the synthesis of metal clusters and their applications in the field of ion sensing.

Timely monitoring abnormal gaits of teenagers is crucial for their physical health and development. Triboelectric nanogenerators (TENGs) are widely used in the wearable field. Choosing high-performance and safe triboelectric materials to monitor abnormal gaits remains challenging. Polyoxometalates (POMs) nanomaterials can effectively serve as triboelectric materials due to rich surface morphology and large specific surface area. The team designed a TENG using POMs nanorods as triboelectric materials by changing the morphology of POMs, achieving an improvement in TENG performance. The optimized TENG has achieved significant results in gait monitoring of teenagers, promoting research in this field.

Although the Navier-Stokes equations are the foundation of modern hydrodynamics, adopting them to quantum systems has so far been a major challenge. Researchers from the Faculty of Physics at the University of Warsaw, Maciej Łebek, M.Sc. and Miłosz Panfil, Ph.D., Prof. UW, have shown that these equations can be generalised to quantum systems, specifically quantum liquids in which the motion of particles is restricted to one dimension.  This discovery opens up new avenues for research into transport in one-dimensional quantum systems. The paper, published in the prestigious Physical Review Letters, was awarded an ‘editors’ suggestion'.
