AbstractCompared with prevailing Zn foil, Zn powders (ZnP) with special‐shaped tunability and large‐scale processability are considered promising anodes for propelling Zn batteries, but face the issue of discrete contact between Zn particles due to their intrinsic monodispersed geometries. Here a novel biomimetic quasi‐skin‐capillary ZnP anode with ionic‐electronic conducting full‐chain networks (ZnP‐FC) is designed, characterized by an aramid nanofiber (ANF) surface coating (skin) and a ZnP‐ANF interwoven inner skeleton (capillary). The epidermal coating not only stabilizes the anode/electrolyte interface to homogenize Zn2+ flux and shields direct contact between H2O and ZnP but also extends inward as a capillary‐like adhesive to anchor ZnP and affords high Zn2+ selectivity for boosting plating/stripping efficiency. Benefiting from these favorable attributes, ZnP‐FC||ZnP‐FC cell enables high kinetics and stable ion migration to afford a long‐term operation for over 1650 h at 5 mA cm−2. Moreover, ZnP‐FC||KV12O30‐y·nH2O full battery harvests a high‐rate capability (15 A g−1) and ultralong cyclic stability (6000 cycles). This work extends the structural engineering landscape of Zn powder anodes for advanced batteries.

AbstractAchieving good compatibility between anodes and cathodes with electrolytes still faces great challenges in Mg metal batteries (MMBs). Recently developed amine‐based electrolytes have enabled reversible Mg anodes with conventional Mg salts through solvation structure regulations but still suffer from low conductivity and poor cathode compatibility. Herein, a Li/Mg double‐salt strategy is proposed to achieve the bulk phase‐interface‐electrode multi‐scale optimization for the amine‐based electrolyte, including ionic conductivity, anode stability, and cathode compatibility. Lithium triflate (LiOTf) serves as a multifunctional additive to compensate for the limitations of single Mg salt electrolyte (MgCl2/3‐methoxypropylamine). Li+ ions accelerate the ions transport in the bulk phase and ions insertion at the cathode side, benefitting to the conductivity and the cathode compatibility. Attributed to the high reduction stability of OTf− anions, the stable Mg anode/interface is also retained. Therefore, the Mg//SS cell achieves an ultralong cycling life for 2100 cycles with the coulombic efficiency of 99.8% at 1.0 mA cm−2 and the full cell also exhibits a superior cycling performance for 1000 cycles at 5 C. Additionally, the batteries with the optimized electrolyte are verified as a proof‐of‐concept for the air‐assembled MMBs. This work emphasizes the crucial role of multifunctional additives in enhancing amine‐based electrolyte performances.

AbstractInspired by the remarkable performance of SnSe‐based compounds in thermoelectrics, a strontium‐tin‐selenium (SrSnSe2) compound is theoretically designed, observing anisotropic Rashba spin‐orbital splitting and strong four‐phonon scattering behavior. Through comprehensive analyses of elastic constants, phonon dispersion, and ab initio molecular dynamics calculations, the mechanical, dynamic, and thermal stability of SrSnSe2 is demonstrated. Electronic calculations reveal that the anisotropic band is decomposed into two distinct bands (heavy and light) due to anisotropic Rashba spin splitting, significantly impacting the electrical transport properties for n‐type and p‐type systems. Moreover, phonon dispersion analysis shows an avoided‐crossing behavior in SrSnSe2, attributed to the expression of the 5s2 lone pair. Notably, four‐phonon scattering in SrSnSe2 lacking phonon bandgap is particularly pronounced compared to SnSe, which is ascribed to the Jahn‐Teller‐like distortion of the SrSe6 octahedron. Combining multiple scattering mechanisms, the optimal thermoelectric performance is evaluated, achieving a ZT of ≈2.57 at 900 K for n‐type and ≈2.47 at 900 K for p‐type SrSnSe₂ under different carrier concentrations and temperatures. The results discover the underlying unusual transport mechanisms in SrSnSe2 thermoelectrics, providing a theoretical case for manipulating anisotropic Rashba band splitting and phonon scattering selection rule.

AbstractThe development of cobalt‐free, high‐energy‐density cathode materials is an important prerequisite for the commercialization of the next generation of high‐energy‐density, cost‐effective lithium batteries. Co‐free spinel LiNi0.5Mn1.5O4 (LNMO) with simultaneous Ni and Mn multi‐cation redox reactions possesses a high theoretical specific capacity of 230 mAh g−1 and a theoretical energy density of 865 Wh kg−1. Unfortunately, LNMO cycled at 2.3–4.95 V suffered from severe interfacial dynamic evolution and electrolyte decomposition, leading to uncontrollable transition metal dissolution and a rapid decrease of reversible specific capacity. Here, It is demonstrated that the addition of an appropriate amount of lithium difluorophosphate (LiDFP) to a common carbonate‐based electrolyte can achieve stable cycling of LNMO in the voltage range of 2.3–4.95 V. The LNMO‐Li cell retained 82.8% of its initial capacity (175.2 mAh g−1) after 300 cycles. The improved cycle performance is attributed to the robust interface formed by the decomposition of LiDFP, which inhibits the dissolution of transition metals and the continued decomposition of the electrolyte. This work provides important insights for the development of the next generation of high‐energy‐density cobalt‐free lithium batteries.

AbstractTransparent microelectrode arrays have proven useful in neural sensing, offering a clear interface for monitoring brain activity without compromising high spatial and temporal resolution. The current landscape of transparent electrode technology faces challenges in developing durable, highly transparent electrodes while maintaining low interface impedance and prioritizing scalable processing and fabrication methods. To address these limitations, we introduce artifact‐resistant transparent MXene microelectrode arrays optimized for high spatiotemporal resolution recording of neural activity. With 60% transmittance at 550 nm, these arrays enable simultaneous imaging and electrophysiology for multimodal neural mapping. Electrochemical characterization shows low impedance of 563 ± 99 kΩ at 1 kHz and a charge storage capacity of 58 mC cm⁻² without chemical doping. In vivo experiments in rodent models demonstrate the transparent arrays' functionality and performance. In a rodent model of chemically‐induced epileptiform activity, we tracked ictal wavefronts via calcium imaging while simultaneously recording seizure onset. In the rat barrel cortex, we recorded multi‐unit activity across cortical depths, showing the feasibility of recording high‐frequency electrophysiological activity. The transparency and optical absorption properties of Ti₃C₂Tx MXene microelectrodes enable high‐quality recordings and simultaneous light‐based stimulation and imaging without contamination from light‐induced artifacts.

Published: September 2024

AbstractAbnormal metabolism and blood supply/O2 imbalance in tumor cells affect drug transport delivery and increase the difficulty of tumor treatment. Controlling tumor growth by inhibiting tumor cell metabolism and regulating progressive embolization in the tumor region provides an innovative basis for constructing tumor therapeutic models. A highly biocompatible and efficient O2‐depleting agent has been investigated to enable in situ precipitation and embolization within the tumor microenvironment. In situ deformation embolizer, Fe‐GA@CaCO3 nano‐assembly (GA: gallic acid), can convert into the large granular size embolization components of Fe(III) precipitates and affluent Ca2+ within the tumor microenvironment. In situ progressive O2 depletion produces Fe(III) precipitates that embolize tumor regions, isolating O2 and nutrients by blocking supply. Meanwhile, affluent Ca2+ acts on the intracellular, causing mitochondrial dysfunction through calcium overload and contributing to irreversible tumor cell damage. Both internal and external routes work synergistically to produce precise functional inhibition of tumors from the inside out, simultaneously responding to both intracellular and the corresponding tumor regions, providing an innovative solution for anti‐tumor therapy.

AbstractOrganic–inorganic halide perovskite solar cells (PSCs) have attracted significant attention in photovoltaic research, owing to their superior optoelectronic properties and cost‐effective manufacturing techniques. However, the unbalanced charge carrier diffusion length in perovskite materials leads to the recombination of photogenerated electrons and holes. The inefficient charge carrier collecting process severely affects the power conversion efficiency (PCE) of the PSCs. Herein, a solution‐processed SnO2 array electron transport layer with precisely tunable micro‐nanostructures is fabricated via a bubble‐template‐assisted approach, serving as both electron transport layers and scaffolds for the perovskite layer. Due to the optimized electron transporting pathway and enlarged perovskite grain size, the PSCs achieve a PCE of 25.35% (25.07% certificated PCE).

Published: September 2024

AbstractAqueous zinc‐bromine (Zn||Br2) batteries are regarded as one of the most promising energy storage devices due to their high safety, theoretical energy density, and low cost. However, the sluggish bromine redox kinetics and the formation of a soluble tribromide (Br3−) hinder their practical applications. Here, it is proposed dispersed single iron atom coordinated with nitrogen atoms (FeN5) in a mesoporous carbon framework (FeSAC‐CMK) as a conductive catalytic bromine host, which possesses porous structure and electrocatalytic functionality of FeN5 species for enhanced confinement and electrocatalytic effect. The active FeN5 species can fix the bromine (Br0) species to suppress the formation of Br3− effectively and bifunctionally catalyze the bromide (Br−)/Br° conversion. These free up 1/3 Br− locked by Br3− complexing agent for enhanced bromine utilization efficiency and conversion reversibility. Accordingly, the Zn||Br2 battery with FeSAC‐CMK delivers an impressive specific capacity of 344 mAh g−1 at 0.2 A g−1 and superior rate capability with 164 mAh g−1 achieved even at 20 A g−1, much higher than that of inactive CMK (262 mAh g−1 at 0.2 A g−1; 6 mAh g−1 at only 8 A g−1). Furthermore, the battery demonstrates excellent cycling performance of 88% capacity retention after 2000 cycles.

AbstractHere a ligand exchange strategy for synthesizing sol–gel oxides is demonstrated to achieve multifunctionality including direct photolithography, high dielectric strength, and high charge carrier mobility, which is challenging to obtain in such oxides. For this purpose, a series of bidentate ligands with azide termini and ethylene‐glycol bridges is synthesized, and these ligands are universally applicable to the synthesis of a variety of dielectric and semiconductor oxides. Optimized photolithography conditions yield a high‐quality ZrO2 dielectric film with a high dielectric constant and strength of ≈18 and ≈7 MV cm−1, respectively. Additionally, this strategy is applied to semiconductor oxides such as In2O3 and ZnO, and the all‐oxide‐patterned solution‐processed thin‐film transistor (TFT) demonstrates a high charge carrier mobility of ≈40 cm2 V−1 s−1. An oxide TFT array is fully photopatterned on a 4‐inch Si wafer; uniform performances are observed across these devices. This study suggests the possibility of realizing multifunctional oxides for application in advanced electronics using simple ligand exchange chemistry.

AbstractManipulating the properties of 2D materials through meticulously engineered artificial heterojunctions holds great promise for novel device applications. However, existing research on the crucial charge‐transfer interactions and energy profile regulation is predominantly focused on 2D van der Waals structures formed via weak van der Waals forces, limiting regulatory efficiency at high costs. Herein, a refined atomic‐molecular heterojunction strategy featuring strong covalent bonds between organic molecule and 2D violet phosphorus (VP) atomic crystal is developed, which enables enhanced charge‐transfer dynamics and customizable band structure regulation at the molecular level. Both experimentally and theoretically, it is demonstrated that grafting efficiency, charge redistribution, and energy gap regulation critically depend on organic electronegativity, providing a low‐cost yet high‐efficiency regulatory effect on a large scale. As a proof of concept, the novel VP‐molecular heterojunctions exhibit optimized performance in diverse application domains, presenting a general platform for future high‐performance device applications.

AbstractAn effective defect passivation strategy is crucial for enhancing the performance of antimony selenosulfide (Sb2(S,Se)3) solar cells, as it significantly influences charge transport and extraction efficiency. Herein, a convenient and novel in situ passivation (ISP) technique is successfully introduced to enhance the performance of Sb2(S,Se)3 solar cells, achieving a champion efficiency of 10.81%, which is among the highest recorded for Sb2(S,Se)3 solar cells to date. The first principles calculations and the experimental data reveal that incorporating sodium selenosulfate in the ISP strategy effectively functions as an in situ selenization, effectively passivating deep‐level cation antisite SbSe defect within the Sb2(S,Se)3 films and significantly suppressing non‐radiative recombination in the devices. Space‐charge‐limited current (SCLC), photoluminescence (PL), and transient absorption spectroscopy (TAS) measurements verify the high quality of the passivated films, showing fewer traps and defects. Moreover, the ISP strategy improved the overall quality of the Sb2(S,Se)3 films, and fine‐tuned the energy levels, thereby facilitating enhanced carrier transport. This study thus provides a straightforward and effective method for passivating deep‐level defects in Sb2(S,Se)3 solar cells.

AbstractDespite the widespread adoption of Zn anodes for aqueous energy storage, the presence of an inherent passivation layer and the polycrystalline interface of commercial Zn foil consistently lead to non‐uniform electrodeposition, undermining stability and practicality. Herein, the study introduces a chemically polished Zn metal anode (CP‐Zn) fabricated via a simple immersion method. This “chemically polishing” process can effectively remove the interfacial passivation layer (de‐passivation), providing ample active sites for plating/stripping and ensuring the uniformly distributed electric field and Zn2+ ion flux. Additionally, selective etching during chemical polishing exposes more (002) crystal planes, promoting homogeneous and smooth zinc deposition while suppressing related side reactions. Demonstrated by CP‐Zn anode, the symmetric cell exhibits stable cycling over 4600 h at 1 mA cm−2 and 240 h at 50% depth of discharge (DOD), with a CP‐Zn||VO2 full cell maintaining ≈75.3% capacity retention over 1000 cycles at 3 A g−1. This chemically polishing strategy presents a promising avenue for advancing the commercialization of aqueous zinc‐ion batteries.

AbstractThe Hydrogel wound dressing with good rewarming property, anti‐freezing property, and adhesion property has important practical significance in medical care for the first and second grade frostbite. The ears, hands, mouth, and nose of field workers on duty and training high cold region are prone to frostbite due to long‐term exposure to in severe cold. Therefore, rapid rewarming of wound surface is the key to the treatment of frostbite. In this paper, antifreeze and rewarming are achieved by photothermal conversion materials and quaternary ammonium salts. Herein, the PAM/CS/MXene30/Betaine5/AgNPs200(PCM30B5A200) hydrogel based on chitosan (CS) and acrylamide (AM) is designed and fabricated by thermally initiated free radical polymerization. The dressing has excellent rewarming properties, anti‐freezing properties, tensile properties, repeatable self‐adhesion and antibacterial properties. In this system, hydrogels are mainly cross‐linked by hydrogen bonds between CS and AM. Betaine is added to the material to make the hydrogel have good freeze‐resistance and flexibility at −24 °C, and can be combined with AgNPs and MXene, to achieve a triple antibacterial. The PCM30B5A200 hydrogel reached the rewarming temperature of 40.5 °C at 9 min. PCM30B5A200 multifunctional hydrogels have good application value in the first and second grade frostbite wounds.

AbstractAs a class of clean oxidants, the hydrogen peroxide (H2O2) has shown great application potential in a variety of fields due to its high energy density and convenient storage condition, while the synthesis of H2O2 by the utilization of green energy technology has currently become one of the attentions in energy field. In this paper, the CdxZn1‐xS (x = 0, 0.2, 0.4, 0.6, 0.8, 1) solid solutions with different zinc‐cadmium molar ratios are prepared by a simple solvothermal route, and the H2O2 evolution performances of materials under illumination and ultrasound conditions are explored. The results show that Cd0.4Zn0.6S has the highest H2O2 yield rate of 2866 µmol/g/h under the synergistic effect of ultrasound and illumination without any sacrificial agent, which is higher than those in ultrasonic or light condition alone, showing piezo‐photocatalytic coupling characteristic. The characterizations including piezoresponse force microscopy (PFM), finite element simulation, in situ electron spin resonance (ESR) reveal that the excellent H2O2 production property of the material should be mainly ascribed to its nanorod structure and e−‐h+ dual‐channel reactivity formed by the bending of its energy band under the piezoelectric effect. This work provides reference and enlightenment for the preparation of H2O2 through the green energy avenue.

Authors: Salah Ahmed , Yevick David 
Published: September 2024

AbstractThis paper presents a Random Forest (RF) machine learning model that relates the DC characteristics and high‐frequency response of a carbon nanotube (CNT) tunnel field‐effect transistor (TFET) with highly doped pockets to the transistor parameters. The analysis of multiple factors for a complex structure as the one studied here becomes expensive with the ordinary simulation techniques and hence machine learning (ML) offers a proficient method to model and enhance the understanding of the key factors that influence the CNT TFET with pockets in considerably reduced time. Numerical simulations are used to generate the data on which the model is trained. This dataset comprises ten input features and four output attributes. The tuned model is capable of predicting the output characteristics of the device with minimal mean squared error (MSE). The RF model is also compared to other ML algorithms to demonstrate its advantage.
