AbstractMany methods are used to manufacture bioinspired adhesive arrays such as photolithography and nanoimprinting methods, which are very high cost and time‐consuming. In this manuscript, projection microstereolithography 3D printing method is firstly adopted to prepare the bioinspired dry adhesive in several micrometers, which is low cost, time saving, convenient and can realize rapid, large‐scale, high‐precision, and controllable complex structure manufacture. The morphology and adhesive properties of four kinds of adhesive with flat punch, mushroom‐shaped, suction cup‐shaped, and titled micropillar structures are investigated. Scanning electron microscope (SEM) observation shows that the very regular pattern of the adhesive is generated and no collapse phenomenon is observed. The adhesion test results show the mushroom‐shaped adhesive reach the maximum adhesion of 15 KPa, which can be maintained after repeated uses. The contact angle of the adhesive is 143.7°, showing the good self‐cleaning ability. The mushroom‐shaped adhesive exhibits excellent adhesion property, high repeatability, and good self‐cleaning ability, which is further applied in grasping and transferring various surfaces such as solar panels, printed circuit board, flanges, and so on.

AbstractTunable emissivity technology is promising for the dynamic regulation of infrared radiation. Herein, infrared electrochromic devices based on thin metal films that operate via a novel hydrogen‐induced metal–insulator transition are demonstrated. The use of thin magnesium–nickel (MgxNi) alloy films as both a variable emissivity material and top conductive electrode simplifies the device structure and ensures that large changes in emissivity can be achieved. The constructed sandwich‐structured electrochromic devices also have polyethyleneimine (PEI) as a middle proton‐conducting electrolyte layer and hydrogen tungsten bronze (HxWO3)/indium tin oxide (ITO) as a bottom ion‐storage layer. Upon application of a voltage of ±2.6 V, the emissivity of the MgxNi/Pd/PEI/HxWO3/ITO device can be reversibly regulated, with emissivity changes of 0.48 and 0.43 in the 3–5 and 7.5–14 µm atmospheric windows, respectively. Under open‐circuit conditions, the high‐emissivity state of the device can be stably maintained for 3 h. The emissivity change is affected by the composition and thickness of the MgxNi film and the device failure mechanism involves the breakage and oxidation of this film after cycling. Corresponding flexible devices that exhibit electrochromism in the visible region have great potential for adaptive thermal camouflage, smart thermal management, and dynamic information displays.

AbstractNitinol (NiTi) alloy is an ideal material for preparing neurointerventional stents due to its excellent mechanical properties and biocompatibility. However, NiTi stents without surface‐specific functionalization cause a high rate of stent thrombosis and in‐stent restenosis after implantation. In ischemic stroke, exosomes have a role in regulating nervous system development, regeneration, vascular remodeling, and neuroinflammation. In this work, the effect of exosome coating on the biocompatibility of NiTi alloy is evaluated. NiTi alloy is successively immersed in relevant solution (sodium alginate, 3‐aminophenylboronic acid, distearoylphosphatidylethanolamine, and exosomes) to form ROS‐responsive exosome coated surfaces. In vitro experiments (platelets, endothelial cells, smooth muscle cells, and macrophages) and in vivo subcutaneous implantation experiments are performed to test coatings for biocompatibility. The results show that the modified NiTi alloy surface has high hydrophilicity, which has the functions of inhibiting platelet aggregation, promoting endothelialization, inhibiting smooth muscle cell migration, anti‐inflammatory, and good tissue biocompatibility. This study develops exosome neurointerventional stent coating as a bioactive drug via reactive oxygen species accumulation in lesions, thus targeting drug release, inhibiting intimal hyperplasia, and reducing inflammation and thrombosis.

AbstractTo solve the problem of tendon adhesion after an operation, an anti‐adhesion membrane is designed, which can inhibit the exogenous healing of tendons and promote endogenous healing. Here, poly[3(S)‐methyl‐morpholine‐2,5‐dione‐co‐lactic acid] P(MMD‐co‐LA) containing alanine units is obtained by melt ring‐opening polymerization (ROP). It can effectively reduce the production of acidic degradation products that cause aseptic inflammation. Then a kind of oriented P(MMD‐co‐LA)/deferoxamine (DFO) anti‐adhesion membrane with good mechanical properties, cell adhesion properties, and induced macrophage polarization properties is constructed by electrospinning. In vitro and in vivo studies have shown that oriented fibrous membranes can down‐regulate the expression of inflammatory cytokines. In addition, the fibrous membrane can up‐regulate the expression of angiogenesis‐related genes, namely HIF1‐α, SDF‐1α, and VEGF, by releasing DFO in situ, thus promoting the revascularization of tendon defects and providing nutritional support for endogenous tendon healing. This method provides a new barrier strategy to reduce tendon adhesion through anti‐inflammation combined with vascularization to inhibit exogenous tendon healing while promoting tendon endogenous healing. The results provide essential insights into the corresponding regulation of the tendon healing microenvironment.

AbstractMagnetotransport, the magnetic field induced electron transport phenomenon through metals and semiconductors, has proven to be a useful technique to tailor the properties of electromagnetic radiation upon interaction with suitable materials and structures. Very recently, magnetotransport has become an important tool to dynamically tailor terahertz (THz) radiation and response of different optical devices. Based on these backgrounds, optically thin, subwavelength superlattice (with alternate arrangement of four metallic films: two non‐magnetic aluminum [Al] and two ferromagnetic nickel [Ni] films, having thickness of each film as 10 nm) metasurfaces are demonstrated, consisting of periodic arrays of asymmetric cut‐wire pair metasurfaces, which have a unique ability to exhibit both frequency and intensity modulation at its hybridized resonances when low‐intensity magnetic fields are applied. Such dynamic tuning characteristics are attributed to the combined effects of spin‐dependent THz magnetotransport in superlattice films, near‐field electromagnetic coupling between the resonators, and lattice mode coupling. Such THz metasurface is further employed for non‐contact detection of external magnetic fields in the range of 0–30 mT, while operating at the optically thin regime. The demonstrated scheme can further be extended to realize THz magneto‐spectroscopy toward devising state‐of‐the‐art photonic and magnetic technologies.

AbstractThe emerging visualization techniques have aroused wide interest for optical information detection and storage. However, they suffer from fairly limited optical information density and poor visual detection performance. Herein, an innovative surface patterning enhanced visualization (SPEV) approach is developed for ultrasensitive naked‐eye detection and RGB‐based high‐density information storage. Through “ship covalently linked in bottle” method, a novel HP‐UiO‐66‐NH2‐based ratiometric fluorescent (RF) composite probe is fabricated, exhibiting remarkably enhanced CdTe QDs encapsulation efficiency and superior dual‐sensing performance for F− and alkaline phosphatase (ALP). Then, the novel surface patterned CdTe QDs@HP‐UiO‐66‐NH2 hydrogel sensor is prepared, emitting multi‐stimuli‐responsive optical information with significantly improved abundance and dimensionality. The pseudo‐color postprocessing of the fluorescence images is performed to convert the analyte‐induced imperceptible color variations into easily perceptible color tonality change, resulting in ultra‐high sensitivity and excellent accuracy for naked‐eye quantitative detection of ALP and F− in human serum. Furthermore, the highly accurate pattern block‐based RGB (PB‐RGB) assay is demonstrated and the concept of RGB‐based 3D patterning codes is presented for highly reliable extraction of quantitative color information and high‐density information storage. The SPEV technique provides a universal route to realize instrument‐free precise visual quantitative detection, high‐density optical information storage, multi‐stimuli‐responsive encryption, and anti‐counterfeiting.

AbstractInhibiting energy metabolism of cancer cells is an effective way to treat cancer but remains a great challenge. Herein, electrostimulation (ES) is applied to effectively suppress energy metabolism of cancer cells to induce rapid cell death, and deeply reveal the underlying mechanisms at the molecular and nanomechanical levels by combined use of fluorescence imaging and atomic force microscopy. Cancer cells are found significantly less tolerant to ES than normal cells; and ES causes “domino effect” to induce mitochondrial dysfunction to impede electron transport chain (ETC) and tricarboxylic acid (TCA) cycle pathways, leading to fatal energy‐supply crisis and death of cancer cells. From the perspective of cell mechanics, the Young's modulus decreases and cytoskeleton destruction of MCF‐7 cell membranes caused by F‐actin depolymerization occurs, along with down‐regulation and sporadic distribution of glucose transporter 1 (GLUT1) after ES. Such a double whammy renders ES highly effective and promising for potential clinical cancer treatments.

Published: April 2023

AbstractElectrically reconfigurable metasurfaces that overcome the static limitations in controlling the fundamental properties of scattered light are opening new avenues for functional flat optics. This work proposes and experimentally demonstrates electrically phase‐tunable mid‐infrared metasurfaces based on the polaritonic coupling of Stark‐tunable intersubband transitions in semiconductor heterostructures and electromagnetic modes in plasmonic nanoresonators. In the applied voltage range of −3 to +3 V, the local phase tuning of the light reflects from the metasurface, which enables the electrical control of the polarization state and wavefront of the reflected wave. Electrical beam polarization control, electrical beam diffraction control, and electrical beam steering are experimentally demonstrated as applications for local phase tunability. The proposed electrically tunable metasurfaces can easily tune the operating wavelength and function at relatively low voltages, which will enable various applications in the mid‐infrared region.

AbstractPure titanium is widely used in clinical implants, but its bioinert properties (poor strength and mediocre effect on bone healing) limit its use under load‐bearing conditions. Modeling on the structure of collagen fibrils and specific nanocrystal plane arrangement of hydroxyapatite in the natural bone, a new type of titanium (Ti) with a highly aligned fibrous‐grained (FG) microstructure is constructed. The improved attributes of FG Ti include high strength (≈950 MPa), outstanding affinity to new bone growth, and tight bone‐implant contact. The bone‐mimicking fibrous grains induce an aligned surface topological structure conducive to forming close contact with osteoblasts and promotes the expression of osteogenic genes. Concurrently, the predominant Ti(0002) crystal plane of FG Ti induces the formation of hydrophilic anatase titanium oxide layers, which accelerate biomineralization. In conclusion, this bioinspired FG Ti not only proves to show mechanical and bone‐regenerative improvements but it also provides a new strategy for the future design of metallic biomaterials.

AbstractThe rational design of a stable and catalytic carbon cathode is crucial for the development of rechargeable lithium‐oxygen (LiO2) batteries. An edge‐site‐free and topological‐defect‐rich graphene‐based material is proposed as a pure carbon cathode that drastically improves LiO2 battery performance, even in the absence of extra catalysts and mediators. The proposed graphene‐based material is synthesized using the advanced template technique coupled with high‐temperature annealing at 1800 °C. The material possesses an edge‐site‐free framework and mesoporosity, which is crucial to achieve excellent electrochemical stability and an ultra‐large capacity (>6700 mAh g−1). Moreover, both experimental and theoretical structural characterization demonstrates the presence of a significant number of topological defects, which are non‐hexagonal carbon rings in the graphene framework. In situ isotopic electrochemical mass spectrometry and theoretical calculations reveal the unique catalysis of topological defects in the formation of amorphous Li2O2, which may be decomposed at low potential (∼ 3.6 V versus Li/Li+) and leads to improved cycle performance. Furthermore, a flexible electrode sheet that excludes organic binders exhibits an extremely long lifetime of up to 307 cycles (>1535 h), in the absence of solid or soluble catalysts. These findings may be used to design robust carbon cathodes for LiO2 batteries.

AbstractThe consumption of fossil fuels has contributed to global warming and other problems. It is urgent to exploit progressive, low‐cost, and environmentally friendly energy storage devices with super high energy density. Rechargeable lithium oxygen batteries (LOBs) with a high theoretical energy density (≈11400 Wh kg−1) are one of the most promising chemical power supplies. MXenes have recently emerged in energy storage and conversion due to their superior conductivity and adjustable structural properties. Here, this paper summarizes the latest research progress in MXene‐based materials in the cathode, anode, separator and electrolyte of LOBs and emphasizes the significance of high conductivity and surface functionalization strategies in the theoretical design and experimental modulation, which promote electrode reaction kinetics and increase the cyclability of LOBs. It also summarizes the prospects and challenges of MXene‐based LOBs and proposes novel strategies to promote battery performance, inspiring the future progress of MXene‐based materials in designing high‐performance LOBs.

AbstractIncreasing the cut‐off voltage of cathodes can improve the energy density of Li||LiCoO2 batteries. However, the electrolyte and cathode suffer from oxidation and deterioration at high voltage, respectively, which lead to rapid battery degradation. Herein, a uniform, highly Li+ conductive cathode electrolyte interphase (CEI) is constructed by using bis‐(benzenesulfonyl)imide (BBSI) as an additive to stabilize Li||LiCoO2 batteries at 4.6 cut‐off voltage with superior cycling and high‐rate performance. Such a CEI is comprised of LiF and conductive Li+ moieties (e.g., Li2S and Li3N), which can improve the Li+ migration, alleviate cathode degradation, and other secondary degradation factors caused by uneven local Li+ intercalation/deintercalation. As expected, Li||LiCoO2 batteries with a 1% BBSI‐containing electrolyte sustain 81.30% of initial capacity after 300 cycles at 0.5C, and 88.27% of initial capacity even after 500 cycles at 2C/3C.

Published: April 2023

AbstractLithium–sulfur (Li–S) batteries are regarded as promising candidates for next‐generation energy storage systems. However, the slow kinetics and shuttle effects of polysulfides hinder their practical applications. Designing high‐efficiency catalysts to enhance the kinetics and suppress shuttling is one major task for the building of durable Li–S batteries. Here, a Co/CoSe junction is reported to catalyzepolysulfide conversion efficiently because the junction has metallic electron mobility and field‐enhanced catalytic activity. The mechanistic investigation reveals that the difference in the work functions of Co and CoSe rearranges the charge distribution in the junction and strengthens the interaction between polysulfides and CoSe, thereby yielding high catalytic activity. In addition, the relative stability of CoSe, as compared to Co, renders the junction durable upon cycling; therefore, demonstrating long‐term catalytic activity. Such a junction makes full use of metal‐like conductivity and field‐enhanced catalysis and provides an alternative approach to enhancing the catalytic conversion of polysulfides.

AbstractThe selenization annealing process is vital for highly efficient kesterite solar cells. Generally, SnS is added during the selenization process, but excessive S and related defects are introduced. Meanwhile, the path of supplementing Sn has never been elucidated. Herein, in order to solve the above problems, a combination of strategies involving SnS and Sn or SnSe or SnSe2 is put forward. And the composition of the vapor inhibiting Sn loss (gaseous SnSe3) and the pathway through which SnSe3 facilitates the formation of Cu2ZnSn(SxSe1‐x)4 (CZTSSe) are clarified. When SnSe2 is added to SnS in the selenization process, grain fusion is effectively promoted. The high crystalline quality kesterite absorber makes the band bending at the GBs optimal and the interface recombination be effectively suppressed. Moreover, cation disorder is remarkably reduced. Therefore, the open‐circuit voltage (Voc) is significantly elevated from 508 to 546 mV with increased fill factor (FF) and short‐circuit current density (Jsc). A state‐of‐the‐art ambient air‐processed kesterite device with 12.89% efficiency is achieved, and the unveiled reaction mechanisms have guiding significance for further optimizing selenization atmosphere and elevating the efficiency of CZTSSe solar cells.
