The capacity to self‐detect and locate damage to underwater infrastructure in emergencies is vital, as materials and technologies that securely facilitate energy and information transmission are crucial in several fields. Herein, the development of a multifunctional supramolecular ionogel (SIG) and SIG‐based devices for use in detecting and locating damage to underwater infrastructure is reported...
Most exogenous electronic skins (e‐skins) currently face challenges of complex structure and poor compatibility with the human body. Utilizing human secretions (e.g., sweat) to develop e‐skins is an effective solution strategy. Here, a new kind of “sweat‐driven” e‐skin is proposed, which realizes energy‐storage and thermal‐management multifunctions. Through the layer‐by‐layer assembly of MXene‐carbon...
Injectable hydrogels find extensive application in the treatment of diabetic wound healing. However, traditional bulk hydrogels are significantly limited due to their nano‐porous structure, which obstructs cell migration and tissue infiltration. Moreover, regulating inflammation and matrix metalloproteinase ‐9 (MMP‐9) expression in diabetic wounds is crucial for enhancing wound healing. This study...
Electrolyte‐gated transistors have strong potential for high‐performance artificial synapses in neuromorphic bio‐interfaces owing to their outstanding synaptic characteristics, low power consumption, and human‐like mechanisms. However, the short retention time is a hurdle to overcome owing to the natural diffusion of protons. Here, a novel modulation technique of ionic conductivity is proposed with...
Achieving a balance between H‐atom adsorption and binding with H2 desorption is crucial for catalyzing hydrogen evolution reaction (HER). In this study, the feasibility of designing and implementing built‐in opposite electric fields (OEF) is demonstrated to enable optimal H atom adsorption and H2 desorption using the Ni3(BO3)2/Ni5P4 heterostructure as an example. Through density functional theory...
MXene nanosheets and ordered porous carbons both have their own advantages and disadvantages. Assembling and combining the advantages of the two will be a good choice for battery electrode hosts of active materials. In this work, an electrostatic separation‐adsorption strategy is proposed to realize the ordered alternating self‐assembly of MXene nanosheets and ordered porous carbon (MPOC), obtaining...
The fabrication of a highly controlled gold (Au) nanohole (NH) array via tip‐based lithography is improved by incorporating a sacrificial layer—a tip‐crash buffer layer. This inclusion mitigates scratches during the nano‐indentation process by employing a 300 nm thick poly(methyl methacrylate) layer as a sacrificial layer on top of the Au film. Such a precaution ensures minimal scratches on the Au...
Bioinspired tactile devices can effectively mimic and reproduce the functions of the human tactile system, presenting significant potential in the field of next‐generation wearable electronics. In particular, memristor‐based bionic tactile devices have attracted considerable attention due to their exceptional characteristics of high flexibility, low power consumption, and adaptability. These devices...
The low photoluminescence (PL) efficiency and unstable features of small blue‐emitting CsPbX3 nanocrystals (NCs) greatly limit their applications in optoelectronics field. Herein, the synergistic and post‐treatment kinetics are studied to create highly bright and anomalous stable violet (peak position of ≈408 nm) and blue (peak position of ∼ 466 nm) emitting perovskite NCs. Ligand and ion exchange...
Compared with all‐small‐molecule (ASM) and other types of organic solar cells (OSCs), the small molecule donor:polymer acceptor (SMD:PA) OSCs develop much slower due to the lack of material matching rules. Herein, by changing the end‐cap substituent of the small molecule donor from ethyl (MPhS‐C2) to benzyl (MPhS‐Ph), the different selection rules of donor properties and thermal annealing (TA) treatment...
Electron transport layers (ETLs) generally contain polar groups for enhancing performance and reducing the work function. Nevertheless, the polar group with high surface energy may cause inferior interfacial compatibility, which challenges the ETLs to balance stability and performance. Here, two conjugated small molecules of ETLs with low surface energy siloxane, namely PDI‐Si and PDIN‐Si, are synthesized...

Recently, embedding organic phosphors into the polyvinyl alcohol (PVA) matrix has emerged as a convenient strategy to obtain efficient long‐lived room temperature phosphorescence (RTP) via forming strong intermolecular hydrogen bonds with organic phosphors to minimize nonradiative relaxations. Regrettably, it is discovered that PVA is unable to trigger RTP emission when a novel functional phosphor...
High‐quality perovskite absorption layer is the fundamental basis for efficient and stable perovskite solar cells (PSCs).
