An amphiphilic copolymer-based marine antifouling coating with zwitterionic sulfobetaine and hydrophobic trifluoroethyl pendants is developed. Copolymers with controlled compositions, molecular weights, and configurations are synthesized for use in coatings. Notably, the random copolymers, balancing hydrophilic and hydrophobic properties, significantly reduce diatom adhesion, even in the presence of marine sediments, outperforming block copolymer analogs.

Single-atom perovskite materials are versatile substances capable of addressing various shortcomings that arise when used individually. These materials demonstrate enhanced catalytic performance, cost efficiency, electron transport capabilities, chemical stability, optical properties, and a tunable band gap. This review paper provides a comprehensive overview of recent synthesis methods, characterization techniques, applications, and future perspectives. Moreover, by sharing insights into the potential direction of single-atom perovskite materials, we aim to inspire ongoing research, ultimately positioning these materials at the forefront of innovation in materials science.

The picture shows the core principle of this work, that is, the process of instantaneous interaction and separation of the probe molecule (methane is present to determine the dead time of the probe molecule) with the most active site on the anodically treated carbon fiber (CF) surface. Subcequently, the energetic changes caused by this interaction were analyzed using inverse gas chromatography at infinite dilution, thereby the surface energetic properties of modified CFs were obtained. Finally, the optimal CFs anodization condition was revealed, as described in the abstract.

The inevitable forming process at high voltages and the low durability of α-C:O_x-based resistive memories limit their use in memory-centric computing systems. We demonstrated highly reliable forming-free Cu-doped α-C:O_x resistive memories via a hybrid conducting path consisting of conductive sp² covalent bonds and Cu filaments, significantly suggesting the advancements and feasibility of carbon-based electronic devices in memory-centric computing systems.

The interlayer Dzyaloshinskii–Moriya interaction (IL-DMI) in a ferromagnetic/nonmagnetic/ferromagnetic metal multilayer is found to be tuned by the interfaces at the nonmagnetic spacer layer. A controllable IL-DMI can be generated by post-processing in a L1₀-FePt/Pt/Fe multilayer. Then, an apparent field-free magnetization switching with controllable switching polarity is achieved.

We assign the high pressure structural phase of transition metal ditelluride (MTe2, M = W or Mo), one of the most extensively investigated material groups. From the accurate assignment of structural phases, we offer comprehensive understanding of the electronic and topological phase evolutions. We can also clearly demonstrate anisotropic pressure-dependent structural evolutions for transition metal ditellurides, which can be generic behaviors of two-dimensional van der Waals materials under pressure.

In this proof-of-concept study, Co₃O₄ nanosheets were used as an anodic water oxidation catalyst in a CO₂ electrolyzer cell, replacing Ir. Synthesized directly on Ti paper porous transport layer with an optimized catalyst loading, current densities of 300 mA cm⁻² at 3.4 V. The CO₂ electrolyzer operated continuously for over 50 hours at 250 mA cm⁻², maintaining CO₂ reduction selectivity and cell stability. This scalable synthesis method supports industrial-level CO₂ electrolysis technology, offering a financially optimal alternative to Ir.

Our study investigates the self-spin swapping phenomenon and measures its intensity. Self-spin swapping occurs in a single magnetic layer, where spin current generated, is influenced by surrounding layers. The spin polarization changes and exerts torque to magnetization which is different to that of spin Hall effect. The intensity is affected by not only the neighboring heavy metal layer but also the sample structure. Au layer enhances spin swapping, while Pt layer disrupts spin information. Thus, symmetric structures show weak spin swapping, while asymmetric structures exhibit stronger spin swapping effects.

The spin-orbit torque \({\tau }_{{\rm{DL}}}\) arising from spin Hall effect is often constrained by low values of spin Hall efficiency \({\theta }_{{\rm{SH}}}\). In this work, introducing phosphorus (P) into platinum (Pt) by ion implantation, thereby forming Pt(P), a significant increase in \({\theta }_{{\rm{SH}}}\) is found. This, in turn, leads to a reduction in the charge current density \({J}_{{\rm{DC}}}\) for magnetization switching. This new amorphous material achieves a remarkable 34-fold increase in \({\theta }_{{\rm{SH}}}\), from 0.034 (pure Pt) to 1.17, making it a strong candidate for energy-efficient spintronic devices and offering a pathway beyond conventional crystalline solids.
