Tunable and Persistent Macroscopic Polarization in Nominally Centrosymmetric Defective Oxides
This work introduces an approach to defect‐mediated symmetry breaking and built‐in polarization in nominally centrosymmetric defective oxides, Gd‐doped CeO2‐δ films, by controlling macroscopic charge asymmetry. Electric field‐driven asymmetric redistribution of oxygen vacancies induces a switchable, stable polarization, leading to a notable, persistent

Van der Waals heterostructures offer exciting possibilities for artificial materials with unique optical, electronic, and spintronic properties. However, their use in the terahertz (THz) range is limited due to material constraints. This study demonstrates scalable, large‐area, crystalline 2D heterostructures, combining topological insulators ...

Strain Engineering of Magnetoresistance and Magnetic Anisotropy in CrSBr
Biaxial compressive strain significantly enhances magnetoresistance and critical saturation fields in thin flakes of the 2D magnet CrSBr, along all three crystallographic axes. First‐principles calculations link these effects to strain‐induced increases in exchange interactions and magnetic anisotropy.

Transition metal oxy/carbo‐nitrides show great promise as catalysts for sustainable processes. A Mn‐Mo mixed‐metal oxynitride attains remarkable performance for the direct synthesis of acetonitrile, an important commodity chemical, via sequential C─N and C─C coupling from syngas (C1) and ammonia (N1) feedstocks.

Giant viral signatures on the Greenland ice sheet
Background Dark pigmented snow and glacier ice algae on glaciers and ice sheets contribute to accelerating melt. The biological controls on these algae, particularly the role of viruses, remain poorly understood.
