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.

China's China Spallation Neutron Source (CSNS) has reached a significant milestone in its Phase II construction, with its first beamline—the neutron technology development station—successfully producing a neutron beam. This marks the completion of equipment development and installation for the beamline. Located in Dongguan, Guangdong province, the facility operates like a super microscope, using neutrons to examine materials and support breakthroughs in renewable energy, aerospace, and bioscience.

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.
