Scientists at California Polytechnic State University have discovered new forms of quantum matter by varying magnetic fields over time. The breakthrough, detailed in Physical Review B, shows that time-dependent control can produce stable quantum states without static equivalents. This could advance quantum computing by making systems more resistant to errors.

Scientists at the University of Konstanz have identified a new type of sliding friction that occurs without physical contact, driven by magnetic interactions. This phenomenon breaks Amontons' law, a 300-year-old physics principle, by showing friction peaks at certain distances rather than increasing steadily with load. The findings appear in Nature Materials.

中国散裂中子源（CSNS）二期工程首个中子束线——中子技术开发站成功产出中子束，标志着该项目设备研制和安装工作的完成。该设施位于广东东莞，由中国科学院高能物理研究所运营，可像超级显微镜一样利用中子探测材料内部细节，支持可再生能源、航空航天和生物科学等领域的研究。

Chemists at Saarland University have created pentasilacyclopentadienide, a silicon analogue of a stable aromatic compound, ending decades of failed attempts. The breakthrough, published in Science, replaces carbon atoms with silicon in a five-atom ring structure. This achievement opens potential for new materials and catalysts in industry.

Researchers at The University of Osaka have developed ultra-small pores in silicon nitride membranes that approach the scale of natural ion channels. These structures enable repeatable opening and closing through voltage-controlled chemical reactions. The advance could aid DNA sequencing and neuromorphic computing.
