While atomic disorder normally promotes glassy states, in some rare cases long-range magnetic order can persist. However, the mechanism, and microscopic characters, remain elusive. Here, Shen et al combine neutron diffraction and resonant X-ray scattering to shed light on the formation of long-range magnetic order in a high-entropy honeycomb van der Waals magnet.

Realization of higher superconducting upper critical field is an important pursuit in both fundamental science and practical applications. Here, the authors synthesize Ta-Te nanowires, which significantly surpass the Pauli paramagnetic limit (the conventional upper bound of critical field) under high pressure.

Hydrogen bonds impact the chemical, physical and biological properties of molecular materials, but are rarely able to induce significant changes in electrical properties. Now a dynamic-to-static transition of hydrogen bonds in an organic–inorganic superlattice has been shown to yield a metal–insulator transition with an on–off ratio of 10⁷ in electrical resistivity.

Interwoven magnetic and non-magnetic layers in TbTi₃Bi₄ overcome kagome frustration, producing coupled elliptical-spiral magnetic and spin-density-wave orders and a very large anomalous Hall effect driven by strong electron–magnetic field interactions.

The kagome superconductor CsV₃Sb₅ exhibits a charge density wave (CDW) as well as superconductivity (SC). Here, the authors find that the CDW transition temperature decreases with decreasing sample thickness to 72 K at 27 atomic layers, but then unexpectedly increases to 120 K at 5 layers, an opposite trend to SC.

Accessing strong correlation effects in Kagome materials remains challenging. Here, the authors realize a Kagome Kondo lattice in CsCr₆Sb₆ exhibiting flat, isolated Kagome bands at the Fermi level.

Catalytic syngas conversion is an essential part of sustainable chemical production but is hindered by the trade-off between conversion activity and product selectivity. Here the authors address this challenge by developing a catalytic shunt strategy.

The chemical-driven large pressure arising inside carbon nanotubes creates energetically stable, flattened, single-layered NbSe₂ nanotubes with enhanced intermolecular electronic interactions, suggesting a chemical approach to produce materials with tailored structural and electronic properties.

The application of pressure effectively suppresses the spin–charge order in trilayer nickelate La₄Ni₃O_10−δ single crystals, leading to the emergence of superconductivity.

Interlayer decoupling plays an essential role in realizing unprecedented properties. Here, authors construct a superlattice consisting of alternating layers of NbSe2 and highly porous hydroxide, realizing interlayer decoupling and thus realizing exotic monolayer behaviors in bulk materials.

Bicyclic boronates are present in various bioactive molecules and functional materials, however, the efficient construction of this skeleton mainly relies on transition-metal-catalyzed processes. Here, the authors develop a practical preparation of bicyclic boronates via metal-free heteroatom-directed alkenyl sp²-C–H borylation and apply it to the synthesis of antibacterial agent QPX7728.
