The fabrication of perovskite light‐emitting diodes (PeLEDs) with vacuum deposition shows great potential and commercial value in realizing large‐area display panel manufacturing. However, the electroluminescence (EL) performance of vacuum‐deposited PeLEDs still lags behind the counterparts fabricated by solution process, especially in the field of blue PeLEDs. Here, the fabrication of high‐quality...
Design high‐loading with superior activity and high atomic efficiency has consistently been a new frontier of heterogeneous catalysis while challenging in synthetic technology. In this work, a universal solid‐state strategy is proposed for large scalable production of high‐loading Ir clusters on porous hollow carbon nanobowls (Ir CSs/PHCNBs). The strong electronic interaction between metallic Ir cluster...
Despite being one of the most promising materials in anode materials, molybdenum sulfide (MoS2) encounters certain obstacles, such as inadequate cycle stability, low conductivity, and unsatisfactory charge‐discharge (CD) rate performance. In this study, a novel approach is employed to address the drawbacks of MoS2. Carbon polymer dots (CPDs) are incorporated to prepare three‐dimensional (3D) nanoflower‐like...
Intervertebral Disc Degeneration
A biomimetic peptide (OAFF) binds to C‐X‐C motif chemokine receptor 1 (CXCR1) and forms fibrous networks on nucleus pulposus stem cells (NPSCs) for mimicking extracellular matrix formation, which induces NPSCs quiescence and ultimately overcomes obstacle in intradiscal injection therapy. More details can be found in article number 2300578 by Lei Wang, Bo Huang, and...
Traditional current‐driven spintronics is limited by localized heating issues and large energy consumption, restricting their data storage density and operation speed. Meanwhile, voltage‐driven spintronics with much lower energy dissipation also suffers from charge‐induced interfacial corrosion. Thereby finding a novel way of tuning ferromagnetism is crucial for spintronics with energy‐saving and...
Maintaining quiescence of stem cells is a potential way to decrease cell nutrition demand for restoring the organization. Herein, a biomimetic peptide to maintain quiescence of stem cells through C‐X‐C motif chemokine ligand 8 (CXCL8)‐C‐X‐C motif chemokine receptor 1 (CXCR1) pathway against intervertebral disc degeneration (IVDD) is developed. First, it is confirmed that quiescence can be induced...
The formation of biofilm and thrombus on medical catheters poses a significant life‐threatening concern. Hydrophilic anti‐biofouling coatings upon catheter surfaces with complex shapes and narrow lumens are demonstrated to have the potential in reducing complications. However, their effectiveness is constrained by poor mechanical stability and weak substrate adhesion. Herein, a novel zwitterionic...
Nickel (Ni) based materials with non‐metal heteroatom doping are competitive substitutes for platinum group catalyst toward alkaline hydrogen oxidation reaction (HOR). However, the incorporation of non‐metal atom into the lattice of conventional fcc phase Ni can easily trigger a structural phase transformation, forming hcp phase nonmetallic intermetallic compounds. Such tangle phenomenon makes it...
Serious capacity and voltage degradation of Li‐rich layered oxides (LLOs) caused by severe interfacial side reactions (ISR), structural instability, and transition metal (TM) dissolution during charge/discharge need to be urgently resolved. Here, it is proposed for the inaugural time that the confinement effect of PO43− dilutes the LiMn6 superstructure units on the surface of LLOs, while deriving...
Although photodynamic immunotherapy has been promoted in the clinical practice of cholangiocarcinoma, the insensitivity to photodynamic immunotherapy remains to be a great problem. This can be largely attributed to an immune‐suppressive tumor microenvironment (TME) manifested as immature myeloid cells and exhausted cytotoxic T lymphocytes. Here, a three‐in‐one oncolytic adenovirus system PEG‐PEI‐Adv‐Catalase‐KillerRed...
Lithium‐sulfur battery (LSB) is widely regarded as the most promising next‐generation energy storage system owing to its high theoretical capacity and low cost. However, the practical application of LSBs is mainly hampered by the low electronic conductivity of the sulfur cathode and the notorious “shuttle effect”, which lead to high voltage polarization, severe over‐charge behavior, and rapid capacity...
Deterministic Magnetization Switching
A sunlight‐controlled, non‐volatile, near 180‐degree deterministic magnetization switching is illustrated in Pt/Co/Pt/PN Si heterostructures with a magnetic bias assistant. The perpendicular magnetic anisotropy (PMA) can be regulated via photoelectron‐induced Fermi level altering and corresponding Rashba field change at the Pt/Co interfaces. The sunlight tuning...
Finding an energy‐efficient way of switching magnetization is crucial in spintronic devices, such as memories. Usually, spins are manipulated by spin‐polarized currents or voltages in various ferromagnetic heterostructures; however, their energy consumption is relatively large. Here, a sunlight control of perpendicular magnetic anisotropy (PMA) in Pt (0.8 nm)/Co (0.65 nm)/Pt (2.5 nm)/PN Si heterojunction...
Strong and tough hydrogels are promising candidates for flexible electronics, biomedical devices, and so on.

In this work, a 2.4 m lithium...
Micro‐supercapacitors (MSCs) are an important energy storage component for future miniaturized electronic systems, yet their key performance indexes such as high‐frequency response, energy density, and cycle life still have a large room to be improved.
