Stoichiometry-Induced Ferromagnetism

The strong spin-moment coupling predicted for altermagnets may have profound implications for new electronic applications. In article number 2405829, Matthew Brahlek and co-workers use a variety of probes to demonstrate that the room-temperature altermagnetic candidate MnTe exhibits competing antiferromagnetic and ferromagnetic orders and identifies their origins. This finding will enable tailoring magnetic properties to test fundamental properties and push forward future spintronic applications.

MXenes

In article number 2405341, Min Seok Jang, Chi Won Ahn, Yonghee Lee, and co-workers study the plasmonic enhancement of 2D MXene, particularly for photonic applications. The image highlights the innovative use of MXenes integrated onto 3D trench nanostructures to achieve significant light-matter interaction at sub-monolayer thicknesses. This interaction leads to remarkable light amplification, significantly enhancing the optical characteristics of the structure. The vibrant colors and detailed graphics are intended to attract the attention of readers and effectively communicate the significance of the research findings.

Solar Hydrogen Production

In article number 2402392, Chun-Yi Chen, Yu-Chieh Lo, Yan-Gu Lin, Akira Yamakata, Yung-Jung Hsu, and co-workers demonstrate the use of double-hollow Au@CdS yolk@shell nanostructures as plasmonic photocatalysts for solar hydrogen production. The plasmon-enhanced activity is exceptional, surpassing the plasmon-induced photoactivities of the state-of-the-art plasmonic photocatalysts ever reported. The superiority originates from the creation of charge separation state, the considerably long-lived hot electrons of plasmonic hollow Au, the magnified electric field, and the advantageous features of double-hollow yolk@shell nanostructures.

Hybrid Halide Perovskites

In article number 2414437, Lingping Kong, Jue Gong, Mercouri G. Kanatzidis, Gang Liu, and co-workers unveil a behavior evolution pattern of the physical properties of hybrid perovskites under hydrostatic compression. This general pattern is applicable to both lead-based and tin-based perovskites assuming 3D and 2D crystal structures. By using the general pattern as an instructional guide and choosing appropriate peak pressures, large bandgap tunability and sensitivity are discovered along with irreversible defect healing and PL enhancement in the tin-based 2D perovskites after pressure treatment.

Immunomodulating Sonocatalytic Nanoagents

In article number 2407349, Hong Luo, Chong Cheng, Lang Ma, and co-workers introduce an immunomodulating sonocatalytic nanoagent with dual-functional Ir-N centers and narrow bandgap for catalytically generating potent O₂ and reactive oxygen species, reversing immunosuppression, and potentiating ovarian cancer immunotherapy.

Hydrogel Electrolytes

In article number 2407050, Lin Zeng, Ji Liu, and co-workers present a hydrogel electrolyte, engineered with preferentially aligned porous structure, and imparted with superior Zn²⁺ conductivity along the pore and fatigue resistance, thus enabling unprecedented capacity retention and long-term stability in flexible aqueous zinc-iodine batteries.

Mixed Ion–Electron Conductors

In article number 2408146, Ji-Soo Jang, Mingjiang Zhong, and co-workers present polymeric mixed ionic–electronic conductors, consisting of charged monomers with ionic liquid-like pendant groups, which not only exhibit solubility in environmentally friendly solvents but also demonstrate long-term stability against humidity, high temperatures, and mechanical deformation. The immobilized ion species foster highly selective interactions of these polymers with nitrogen dioxide, paving the way for the development of stretchable sensing devices capable of functioning at exceptionally high temperatures.

Enzyme Immobilization

In article number 2406097, Fernando López-Gallego and co-workers develop a universal method for encapsulating single gram-negative microbes with polymeric coatings to fabricate synthetic spores that selectively bind His-tagged enzymes. These synthetic spores serve as biocatalytic materials for the one-pot oxidative amination of diols into amino alcohols, facilitated by the cooperative catalysis between intracellular and extracellular enzymes that maintain their performance in consecutive batch cycles.

Multifunctional Nano-Optical Electrodes

In article number 2405832, Dongyuan Zhao, Yin Fang, and co-workers present multifunctional nano-optical electrodes (NOEs), featuring mesoporous carbon shells encapsulating superparamagnetic ferric oxide nanocluster cores, enable MRI-guided, non-genetic near-infrared neuromodulation. This innovative approach heralds a new era for the advancement of noninvasive, precision-targeted neuromodulation therapies in the management of neurological disorders.
