Developing inventive approaches to control crystallization and suppress trap defects in perovskite films is crucial for achieving efficient perovskite photovoltaics. Here, a synchronous regulation strategy is developed that involves the infusion of a zwitterionic ionic liquid additive, pyrrolidinium thiocyanate (PySCN), into the perovskite precursor to optimize the subsequent crystallization and defects...
Urea, as one of the most sustainable organic solutes, denies the high salt consumption in commercial electrolytes with its peculiar solubility in water. The bi‐mixture of urea‐H2O shows the eutectic feature for increased attention in aqueous Zn‐ion electrochemical energy storage (AZEES) technologies. While the state‐of‐the‐art aqueous electrolyte recipes are still pursuing the high‐concentrated salt...
Although lithium–sulfur (Li–S) batteries have broad market prospects due to their high theoretical energy density and potential cost‐effectiveness, the practical applications still face serious shuttle effects of polysulfides (LiPSs) and slow redox reactions. Therefore, in this paper, cobalt nitride nanoparticles encapsulated in nitrogen‐doped carbon nanotube (CoN@NCNT) are prepared as a functional...
Guided by a superb dual‐ions cosubstitution strategy, two novel, highly optically anisotropic hybrid bismuth halides are designed and synthesized. The first compound, Gu3Bi2NO3Cl8 (Gu = C(NH2)3), is developed using the 2D perovskite halide Cs3Bi2Cl9 as the maternal structure. This involved substituting all Cs+ cations with organic Gu+ and replacing some Cl− anions with [NO3]−. Further substitution...
Titanium disulfide (TiS2) is a promising anode material for sodium‐ion batteries due to its high theoretical capacity, but it suffers from severe volume variation and shuttle effect of the intermediate polysulfides.

The resulting fly ash‐cellulose (FACNF) separators enable a high ion conductivity...
Gallium‐based (Ga‐based) liquid metals have attracted considerable interest due to their low melting points, enabling them to feature both liquid properties and metallic properties at room temperature. In light of this, Ga‐based liquid metals also possess excellent deformability, high electrical and thermal conductivity, superior metal affinity, and unique self‐limited surface oxide, making them popular...
Activation of small molecules is considered to be a central concern in the theoretical investigation of environment‐ and energy‐related catalytic conversions. Sub‐nanostructured frustrated Lewis pairs (FLPs) have been an emerging research hotspot in recent years due to their advantages in small molecule activation. Although the progress of catalytic applications of FLPs is increasingly reported, the...
LiNO3 has attracted intensive attention as a promising electrolyte additive to regulate Li deposition behavior as it can form favorable Li3N, LiNxOy species to improve the interfacial stability. However, the inferior solubility in carbonate‐based electrolyte restricts its application in high‐voltage Li metal batteries. Herein, an artificial composite layer (referred to as PML) composed of LiNO3 and...
Nanozyme‐based metabolic regulation triggered by tumor‐specific endogenous stimuli has emerged as a promising therapeutic strategy for tumors. The current efficacy, however, is constrained by the limited concentration of endogenous substrates and the metabolic plasticity of tumors. Consequently, the implementation of efficient metabolic regulation in tumor therapy is urgently needed. Herein, a versatile...
Although bioactive compounds (BCs) have many important functions, their applications are greatly limited due to their own defects. The development of nanocarriers (NCs) technology has gradually overcome the defects of BCs. NCs are equally important as BCs to some extent. Self‐assembly (SA) methods to build NCs have many advantages than chemical methods, and SA has significant impact on the structure...
Aqueous aluminum‐ion batteries are attractive post‐lithium battery technologies for large‐scale energy storage in virtue of abundant and low‐cost Al metal anode offering ultrahigh capacity via a three‐electron redox reaction.

Inspired by natural swarms, various methods are developed to create artificial magnetic microrobotic collectives. However, these magnetic collectives typically receive identical control inputs from a common external magnetic field, limiting their ability to operate independently. And they often rely on interfaces or boundaries for controlled movement, posing challenges for independent, three‐dimensional(3D)...
Hypergolicity is a highly desired characteristic for hybrid rocket engine‐based fuels because it eliminates the need for a separate ignition system. Introducing hypergolic additives into conventional fuels through physical mixing is a feasible approach, but achieving highly reliable hypergolic ignition and energy release remains a major challenge.
