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...
Normally, only noncentrosymmetric structure of the materials can potentially be piezoelectric. Thus, it is limited in the field of piezoelectricity for the centrosymmetric structure of the material. In this work, the performance of piezoelectricity is successfully achieved from centrosymmetric SrFeO3‐x by modulating oxygen vacancies, which have a surface piezoelectric potential up to 93 mV by using...
Atomicforce microscopy (AFM)‐based scanning probing techniques, including Kelvinprobe force microscopy (KPFM) and conductive atomic force microscopy (C‐AFM), have been widely applied to investigate thelocal electromagnetic, physical, or molecular characteristics of functional materials on a microscopic scale. The microscopic inhomogeneities of the electronic properties of polycrystalline photovoltaic...
Space charge transfer of heterostructures driven by the work‐function‐induced built‐in field can regulate the electronic structure of catalysts and boost the catalytic activity. Herein, an epitaxial heterojunction catalyst of CoO/Mo2C with interfacial electron redistribution induced by work functions (WFs) is constructed for overall water splitting via a novel top‐down strategy. Theoretical simulations...
TiNb2O7, as a promising alternative of Li4Ti5O12, exhibits giant potential as low‐temperature anode due to its higher theoretical capacity and comparable structural stability. However, the sluggish electronic conductivity still remains a challenge. Herein, bulk modification of Cu+ doping in porous TiNb2O7 microsphere is proposed via a simple one‐step solvothermal method with subsequent calcination...
Biomimetic Nanoparticles
In article number 2301439, Rutong Yu, Xiuping Zhou, and co‐workers construct a Trojan‐horse‐like nanoparticle system (R‐NKm@NPs), which traverses across the blood‐brain barrier (BBB) and targets glioblastoma through the natural killer (NK) cell membrane decorated with cRGD. Notably, the R‐NKm@NPs exhibit good antitumor ability by locally releasing temozolomide (TMZ) and IL‐15,...
Although the chemo‐ and immuno‐therapies have obtained good responses for several solid tumors, including those with brain metastasis, their clinical efficacy in glioblastoma (GBM) is disappointing. The lack of safe and effective delivery systems across the blood‐brain barrier (BBB) and the immunosuppressive tumor microenvironment (TME) are two main hurdles for GBM therapy. Herein, a Trojan‐horse‐like...
Fe‐based mixed phosphate cathodes for Na‐ion batteries usually possess weak rate capacity and cycle stability challenges resulting from sluggish diffusion kinetics and poor conductivity under the relatively low preparation temperature. Here, the excellent sodium storage capability of this system is obtained by introducing the high‐entropy doping to enhance the electronic and ionic conductivity. As...
Improved Lithium Sulfur Batteries
NiCo2S4‐x nanoplates with sulfur vacancy are grown on the flexible carbon fiber paper as the interlayer of the Li‐S battery. The 2D nanoplate morphology of NiCo2S4‐x increases the effective adsorption sites for lithium polysulfides (LiPSs), and the Lewis acidic sulfur vacancy could regulate the precipitation and conversion behaviors of LiPSs, resulting in improved...
The low conductivity of sulfur and the shuttle effect of lithium polysulfides (LiPSs) are the two intrinsic obstacles that limit the application of lithium–sulfur batteries (LSBs). Herein, a sulfur vacancy introduced NiCo2S4 nanosheet array grown on carbon nanofiber (CNF) membrane (NiCo2S4‐x/CNF) is proposed to serve as a self‐supporting and binder‐free interlayer in LSBs. The conductive CNF skeleton...
Mixed matrix membranes (MMMs), conjugating the advantages of flexible processing‐ability of polymers and high‐speed mass transfer of porous fillers, are recognized as the next‐generation high‐performance CO2 capture membranes for solving the current global climate challenge. However, controlling the crystallization of porous metal‐organic frameworks (MOFs) and thus the close stacking of MOF nanocrystals...
Gas Separation Membranes
In article number 2208177, Ming‐Jie Yin, Quan‐Fu An, and co‐workers propose a “confined swelling coupled solvent controlled crystallization” strategy to rapid preparation of mixed matrix membrane for CO2 capture. The fabricated membrane exhibits 4‐fold enhancement in CO2 permeability, benefiting from the high ZIF‐8 loading creating additional speedy mass transfer channel for...
Virus Coinfection Diagnosis
In article number 2200854, Jing Cheng, Youchun Xu, and co‐workers develop MAPnavi, a platform for rapid and sensitive differential diagnosis of respiratory viral coinfection. In the darkest hour before the dawn against the epidemic, MAPnavi is sailing with a centrifugal booster, revealing the true face of cunning viruses from the respiratory tract.
The ongoing pandemic caused by severe acute respiratory syndrome coronavirus 2 is profoundly influencing the global healthcare system and people's daily lives. The high resource consumption of coronavirus disease 2019 (COVID‐19) is resulting in insufficient surveillance of coinfection or resurgence of other critical respiratory epidemics, which is of public concern. To facilitate evaluation of the...
Immune checkpoint blockade (ICB) is demonstrating great potential in cancer immunotherapy nowadays. Yet, the low response rate to ICB remains an urgent challenge for tumor immunotherapy. A pH and matrix metalloproteinase dual‐sensitive micellar nanocarrier showing spatio‐temporally controlled release of anti‐PD‐1 antibody (aPD‐1) and paclitaxel (PTX) in solid tumors is prepared to realize synergistic...
In article number 1803613, Larysa Baraban, Denys Makarov, and co‐workers present an experimental and theoretical study of visible light‐driven Ag/AgCl Janus micromotors revealing high motility in pure H2O. The propulsion efficiency is dependent on the intensity of visible light and contributed by the coupled effect of the plasmonic light absorption of Ag/AgCl and the efficient photochemical decomposition...
Visible light‐driven nano/micromotors are promising candidates for biomedical and environmental applications. This study demonstrates blue light‐driven Ag/AgCl‐based spherical Janus micromotors, which couple plasmonic light absorption with the photochemical decomposition of AgCl.
