However, a systematic and quantitative analysis of MPL is lacking, impeding effective evaluation and manipulation of this detrimental issue. In this study, we transition from a qualitative analysis to a quantitative one by conducting a detailed examination of the MPL. Our findings reveal that slender lithium dendrites reduces the lifespan and safety of LIB by increasing the side reaction rates and promoting the formation of dead lithium. To further evaluate the extent of the detrimental effect of MPL, we propose the specific surface area (SSA) as a critical metric, and develop an in situ method integrating expansion force and electrochemical impedance spectroscopy to estimate SSA. Finally, we introduce a pulse current protocol to manipulate hazardous MLP. Phase field model simulations and experiments demonstrate that this protocol significantly enhances the reversibility of plated lithium. This research offers a novel morphological perspective on lithium plating, providing a more detailed fundamental understanding that facilitates effective evaluation and manipulation of plated lithium, thereby enhancing the safety and extending the cycle life of LIBs.image","PeriodicalId":48538,"journal":{"name":"Infomat","volume":null,"pages":null},"PeriodicalIF":22.7,"publicationDate":"2024-07-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141805432","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Herein, a sub-nano cluster (Pd, Ru, and PdRu alloy) decoration strategy is proposed to manipulate the photogenerated carrier behavior in MoS2 to optimize the optoelectronic properties. After decoration, electrons can flow into sub-nano cluster through PdS bonds and then return to MoS2 through RuS bonds at the sub-nano cluster/MoS2 interface when holes are left in the channel for collection to achieve efficient carrier separation. In addition, the formation of metalS bonds also leads to the generation of mid-gap states, which enables light absorption over a wide wavelength range. Therefore, the photodetector based on PdRu/MoS2 shows broadband photodetection ability from 532 to 1550 nm with high responsivity/external quantum efficiency of 310.8 A W−1/7 × 104% (532 nm), 4.2 A W−1/527% (980 nm), and 7.14 mA W−1/0.5% (1550 nm), as well as a fast response speed (rise/decay time of 11.5/12.0 ms).

Currently, the study of 2D TMDs-based flexible strain sensors mainly focuses on improving the performance of sensitivity, response, detection resolution, cyclic stability, and so on. There are few reports on power consumption despite that it is of significant importance for wearable electronic systems. It is still challenging to effectively reduce the power consumption for prolonging the endurance of electronic systems. Herein, we propose a novel approach to realize ultra-low power consumption strain sensors by reducing the contact resistance between metal electrodes and 2D MoS2. A dendritic bilayer MoS2 has been designed and synthesized by a modified CVD method. Large-area edge contact has been introduced in the dendritic MoS2, resulting in decreased the contact resistance significantly. The contact resistance can be down to 5.4 kΩ μm, which is two orders of magnitude lower than the conventional MoS2 devices. We fabricate a flexible strain sensor, exhibiting superior sensitivity in detecting strains with high resolution (0.04%) and an ultra-low power consumption (33.0 pW). This study paves the way for future wearable and flexible sensing electronics with high sensitivity and ultra-low power consumption.","PeriodicalId":48538,"journal":{"name":"Infomat","volume":null,"pages":null},"PeriodicalIF":22.7,"publicationDate":"2024-07-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141739817","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To implement autonomously self-healing octopus-inspired architectures, a dynamic polymer reflow model based on structural and material design suggests criteria for three-dimensional patterning self-healing elastomers. In addition, self-healing multi-layered microstructures with different moduli endows efficient self-healing ability, human-friendly reversible bio-adhesion, and stable mechanical deformability. Through programmed molecular behavior of microlevel hybrid multiscale architectures, the bioinspired adhesive patch exhibited robust adhesion against rough skin surface under both dry and underwater conditions while enabling autonomous adhesion restoring performance after damaged (over 95% healing efficiency under both conditions for 24 h at 30°C). Finally, we developed a self-healing skin-mountable adhesive electronics with repeated attachment and minimal skin irritation by laminating thin gold electrodes on octopus-like structures.

In this work, we report that a newly explored van der Waals (vdW) layered material, SnP2Se6, possessing excellent field regulation capabilities and behaviors as an ideal candidate for PTE detector implementation.

By effectively modulating the SnP2Se6 localized carrier concentration, which in turn leads to inhomogeneous Seebeck coefficients, the designed dual‐gate PTE detector with 2D SnP2Se6 channel demonstrates wide spectral photoresponse in telecommunication bands, yielding high responsivity (R = 1.2 mA W−1) and detectivity (D* = 6 × 109 Jones) under 1550 nm light illumination.

This work reports unprecedented stability in aluminum and fluorine co-doped ZnO (AFZO) films prepared by pulse laser deposition. The AFZO can retain a mobility of 60 cm2 V−1 s−1, an electron concentration of 4.5 × 1020 cm−3, and a visible transmittance of 91% after air-annealing at 600°C. Comprehensive defect characterization and first principles calculations have revealed that the offset of substitutional aluminum by zinc vacancy is responsible for the instability observed in aluminum-doped ZnO, and the pairing between fluorine substitution and zinc vacancy ensures the high-temperature stability of AFZO. The utility of AFZO in enabling the epitaxial growth of (AlxGa1−x)2O3 film within a high-temperature, oxygen-rich environment is demonstrated, facilitating the development of a self-powered solar-blind ultraviolet Schottky photodiode. Furthermore, the high-mobility AFZO transparent electrode enables perovskite solar cells to achieve improved power conversion efficiency by balancing the electron concentration-dependent conductivity and transmittance.
