Electrical control of the anomalous Hall effect (AHE) provides an important gateway to reveal and regulate topological properties of spins. However, direct, immediate electrical tuning of the AHE in materials has been elusive, unfeasible, and rarely reported. Here, we demonstrate direct, immediate, nonlinear, electric current regulation of the AHE in a single, novel, van der Waals, room-temperature, ferromagnetic, ultrathin, two-dimensional (2D) crystal for intrinsic sensitivity of nodal electronic structures induced by 2D spin-orbit coupling (SOC) in a 2D quantum limit with an ultrasmall current (∼102 A cm−2). The multivalued electrical tuning of anomalous Hall resistance (RAHE) () is up to 584% and remains 126% at room temperature. The squared correlation between RAHE and longitudinal resistance indicates an SOC-dominated Berry curvature-induced AHE. This immediate-current AHE with distinct dependence on the dimension, crystal layer, and electronic topology provides unique quantum platforms for probing the essence of the dimension and for low-power spintronics and brain-like quantum devices.
异常霍尔效应（AHE）的电控制是揭示和调控自旋拓扑性质的重要途径。然而，材料中AHE的直接，即时电调谐一直是难以捉摸的，不可行的，很少报道。在这里，我们展示了AHE在一个单一的、新颖的、范德华的、室温的、铁磁的、超薄的二维（2D）晶体中直接的、即时的、非线性的电流调节，用于在二维量子极限下由二维自旋轨道耦合（SOC）引起的节点电子结构的固有灵敏度，具有超小电流（~ 102 a cm−2）。异常霍尔电阻（RAHE1RAHE2 * 100%）的多值电调谐高达584%，在室温下保持126%。RAHE与纵向电阻之间的平方相关性表明soc主导的Berry曲率诱导AHE。这种对维度、晶体层和电子拓扑具有明显依赖性的即时电流AHE为探索维度的本质、低功率自旋电子学和类脑量子器件提供了独特的量子平台。

High-entropy alloys (HEAs) have a wide range of applications due to their excellent physical and chemical properties. However, traditional synthesis routes always require high temperatures over 923 K or have high equipment requirements. Here, we developed a liquid metal gallium (Ga)-mediated strategy using only a commercial vortex mixer and metal powders to synthesize HEAs near room temperature (303 K) with low power (7 W). A variety of HEAs were successfully prepared, and the yield can be expanded to over 10 g each time. The mechanistic investigation proved that Ga continued to flow under the mechanical force and exposed fresh surfaces to contact the metal, thereby promoting the process of metal dissolution in Ga and forming HEAs. These as-prepared HEAs can be used for catalysis in electrochemical oxygen evolution reactions with low overpotential and high durability. This strategy provides an innovative method for low-energy synthesis of HEAs at room temperature.

The growing demand for metallic materials resistant to both environmental corrosion and hydrogen embrittlement under municipal wastewater conditions presents a significant challenge. Achieving superior resistance to both simultaneously is difficult due to microbial and acid-induced corrosion in wastewater alongside hydrogen embrittlement caused by the generation of free hydrogen during corrosion. These complex loading scenarios require materials capable of withstanding both forms of degradation. Here, we present a FeCoMnNiCu alloy, designed using the multiprincipal element concept, which forms a protective passive film and exhibits high resistance to both microbial and oxidative acid-induced corrosion. Furthermore, it shows exceptional resistance to hydrogen embrittlement with a hydrogen embrittlement index of approximately 4.01%. This is achievable because the alloy has a very low hydrogen diffusion coefficient and promotes hydrogen-induced twinning through the reduction of stacking fault energy. These properties establish the new alloy as a promising solution for components exposed to corrosive, hydrogen-rich municipal wastewater environments.

The traditional three-dimensional (3D) printing technique requires high energy to break and re-form the metal bonds. Here, we present the latest discovery of the metal polymerization reaction at room temperature with the non-breaking and re-forming bond method, which is similar to the polymerization phenomenon of the AB reaction. The A and B in the AB reaction represent the eutectic gallium–indium liquid metal and transition metal alloy, respectively, and their same atomic structures generate the aggregation to form the new alloy phases, showing that the printed Ga–In–Cu alloy has superior mechanical properties. Moreover, the AB reaction model is established to elucidate the reaction mechanism between the A and the B, which exhibits excellent printable performance. This polymerization reaction of the alloys pioneers a novel approach to the formation of alloys, which has become one of the important trends in future manufacturing industries.

π-d conjugated coordination polymers (CCPs) with unique stacking structures are developed for the nanoconfinement of iodine by chemisorption in an aqueous Zn-I2 battery. The stacking structure allows for the accumulation of localized electrons on a well-ordered atomic array, which enhances the built-in electric field, thereby optimizing the environment for the evolution of iodine species. The assembled I−/I0 two-electron-transfer Zn-I2 battery provides a specific capacity of 226.4 mAh g−1 at 0.4 A g−1 (an overpotential of 42 mV) and achieves 60,000 cycles at 10 A g−1. The assembled I−/I0/I+ four-electron-transfer Zn-I2 battery provides a specific capacity of up to 337.1 mAh g−1 at 5 A g−1 with outstanding rate performance (155.6 mAh g−1 at 50 A g−1) and cycle performance (12,000 cycles at 10 A g−1). This study employs targeted molecular design and systematic optimization to develop a high-performance aqueous Zn-I2 battery electrode material enabled with the promising four-electron transfer reaction.

2D metal halide perovskites have enabled significant stability improvements in perovskite devices, particularly in resistance to moisture. However, some 2D perovskites are even more susceptible to photooxidation compared to 3D perovskites. This is particularly true for more commonly investigated Ruddlesden-Popper (RP) perovskites, which exhibit increased susceptibility to photoinduced degradation compared to Dion-Jacobson (DJ) perovskites. Comparisons between different RP and DJ perovskites reveal that this phenomenon cannot be explained by commonly proposed differences in superoxide ion generation, interlayer distance, or lattice structural rigidity differences. Instead, the resistance to photooxidation of DJ perovskites can be attributed to a decreased likelihood of double deprotonation events (compared to single deprotonation events in RP perovskites) required for the loss of organic cations and perovskite decomposition. Consequently, DJ perovskites are less susceptible to oxidative degradation (induced both photo- and electrochemically), which leads to improved operational stability of solar cells based on these materials.
