Structural damage of Ni‐rich layered oxide cathodes such as LiNi0.8Co0.1Mn0.1O2 (NCM811) and serious interfacial side reactions and physical contact failures with sulfide electrolytes (SEs) are the main obstacles restricting ≥4.6 V high‐voltage cyclability of all‐solid‐state lithium batteries (ASSLBs). To tackle this constraint, here, a modified NCM811 with Li3PO4 coating and B/P co‐doping using inexpensive...
Facilitating C─N bond cleavage and promoting *COO desorption are essential yet challenging in urea oxidation reactions (UORs). Herein a novel interfacial coordination assembly protocol is established to modify the Co‐phytate coordination complex on the Ni‐based metal–organic framework (MOF) nanosheet array (CC/Ni‐BDC@Co‐PA) toward boosted and sustained UOR electrocatalysis.

Non‐small cell lung cancer (NSCLC) is the most common pathological type of lung cancer , accounting for approximately 85% of lung cancers. For more than 40 years, platinum (Pt)‐based drugs are still one of the most widely used anticancer drugs even in the era of precision medicine and immunotherapy. However, the clinical limitations of Pt‐based drugs, such as serious side effects and drug resistance,...
Colorful circularly polarized organic ultralong room temperature phosphorescence (CP‐OURTP) materials have attracted much attention due to their superior optoelectronic properties for various applications. However, the development of colorful CP‐OURTP materials in a single‐component molecular system is currently facing great challenges. Herein, a feasible strategy is proposed to develop colorful CP‐OURTP...
2D materials that can provide long‐range ordered channels in thin‐film form are highly desirable for proton exchange membranes (PEMs). Covalent organic framework nanosheets (CONs) are promising 2D materials possessing intrinsic porosity and high processability. However, the potential of CONs in PEMs is limited by loose sheet stacking and interfacial grain boundary, which lead to unsatisfied mechanical...
Exploring active and durable Ni‐based materials with optimized electronic and architectural engineering to promote the urea oxidation reaction (UOR) is pivotal for the urea‐related technologies. Herein a 3D self‐supported hierarchical‐architectured nanoarray electrode (CC/MnNi@NC) is proposed in which 1D N‐doped carbon nanotubes (N‐CNTs) with 0D MnNi nanoparticles (NPs) encapsulation are intertwined...
Human ocean activities are inseparable from the supply of energy. The energy contained in the gas‐phase components dispersed in seawater is a potential universal energy source for eupelagic or deep‐sea equipment. However, the low energy density of bubbles dispersed in water introduces severe challenges to the potential energy harvesting of gas‐phase components. Here, a super‐aerophilic biomimetic...
Sonodynamic therapy as a promising noninvasive modality is being developed for tumor therapy, but there is a lack of next‐generation sonosensitizers that can generate full ROS at high yields and simultaneously deplete elevated levels of glutathione (GSH) in tumor cells. Semiconductor p‐n junctions are engineered as high‐efficacy sonosensitizers for sonodynamic tumor eradication using pyridine N‐doped...
Chromium (VI) and arsenic (V) oxoanions are major toxic heavy metal pollutants in water threatening both human health and environmental safety. Herein, the development is reported of a bifunctional ionic covalent organic network (iCON) with integrated guanidinium and phenol units to simultaneously sequester chromate and arsenate in water via a synergistic ion‐exchange‐redox process. The guanidinium...
