Published: July 2023

AbstractHalide perovskites are promising candidates for resistive memories (memristors) due to their mixed electronic/ionic conductivity and the real activation mechanism is currently under debate. In order to unveil the role of the metal contact and its connection with the activation process, four model systems are screened on halide perovskite memristors: Nearly inert metals (Au and Pt), low reactivity contacts (Cu), highly reactive contact (Ag and Al), and pre‐oxidized metal in the form of AgI. It is revealed that the threshold voltage for activation of the memory effect is highly connected with the electrochemical activity of the metals. Redox/capacitive peaks are observed for reactive metals at positive potentials and charged ions are formed that can follow the electrical field. Activation proceeds by formation of conductive filaments, either by the direct migration of the charged metals or by an increase in the concentration of halide vacancies generated by this electrochemical reaction. Importantly, the use of pre‐oxidized Ag+ ions leads to very low threshold voltages of ≈0.2 V indicating that an additional electrochemical reaction is not needed in this system to activate the memristor. Overall, the effect of the metal contact is clarified, and it is revealed that AgI is a very promising interfacial layer for low‐energy applications.

AbstractAluminum–sulfur batteries (ASBs) are deemed to be alternatives to meet the increasing demands for energy storage due to their high theoretical capacity, high safety, low cost, and the rich abundances of Al and S. However, the challenging problems including sluggish conversion kinetics, inferior electrolyte compatibility, and potential dendrite formation are still remained. This review comprehensively focuses on summarizing the specific strategies from polysulfide shuttling inhibition to form smooth anodic Al activation/deposition. Especially, innovations in cathodic side for achieving electrochemical kinetic modulations, electrolyte optimizations, and anodic interface mediations are discussed. Upon detailed elaborating the formation process, influencing factors, and their interactions in the Al–S electrochemistry, a comprehensive summary of their causative mechanisms and the corresponding strategies are provided, including optimization of electrolytes, innovative in situ detections, and precise electrocatalytic strategies. Based on such a systematic understanding in the Al–S electrochemistry, the possible electrochemical reaction mechanism is deciphered more clearly and enlightened practical strategies on the future development of stable ASBs. Furthermore, future opportunities and directions of high‐performance conversion‐based Al–S batteries for large‐scale energy storage applications are highlighted.

Published: July 2023

AbstractNonlinear optical (NLO) materials are of great importance for applications in lasers, atomic clocks, free‐space communication, etc. Herein, inspired by the recent prediction of excellent second harmonic generation (SHG) performance in van der Waals (vdW) materials with 1D building blocks, 14 new NLO materials are found from 244 bulk crystals constructed with 1D polymers using high‐throughput first‐principles calculations. Nearly half of the new NLO materials exhibit superior NLO performance with SHG susceptibilities approaching the theoretical upper limit. The 2D form of 11 candidates inherits the NLO property covering UV, visible, and infrared regions. Bader charge analysis reveals that the SHG susceptibility is determined by the charge difference of ions on the chains. Finally, it is proposed that superior NLO materials can be found in materials with proper bandgaps and large charge differences on the chains. This work not only screens out candidates with outstanding NLO performance in vdW materials with 1D building blocks but also provides a guideline for the search and design of NLO vdW 1D polymer patterns with excellent NLO properties.

Published: July 2023

AbstractOrganic photodetectors, as an emerging wearable photoplethysmographic (PPG) technology, offer exciting opportunities for next‐generation photonic healthcare electronics. However, the mutual restraints among photoresponse, structure complexity, and fabrication cost have intrinsically limited the development of organic photodetectors for ubiquitous health monitoring in daily activities. Here, an effective route to dramatically boost the performance of organic photodetectors with a solution‐processed integration circuit for health monitoring application is reported. Through creating an ideal metal–semiconductor junction interface that minimizes the trap states within the device, solution‐printed organic field‐effect transistors (OFETs) are achieved with an ultrahigh signal amplification efficiency of 37.1 S A−1, approaching the theoretical thermionic limit. Consequently, monolithic integration of the OFET with an organic photoconductor enables the remarkable amplification of photoresponse signal‐to‐noise ratio by more than four orders of magnitude from 5.5 to 4.6 × 105, which is able to meet the demand for accurately extracting physiological information from the PPG waveforms. This work offers an effective and versatile approach to greatly enhance the photodetector performance, promising to revolutionize health monitoring technologies.

Published: July 2023

The fast degradation of the charge‐extraction interface at indium tin oxide (ITO) poses a significant obstacle to achieving long‐term stability for organic solar cells (OSCs). Herein, a sustainable approach for recycling non‐sustainable indium to construct efficient and stable OSCs and scale‐up modules is developed. It is revealed that the recovered indium chloride (InCl3) from indium oxide waste can be applied as an effective hole‐selective interfacial layer for the ITO electrode (noted as InCl3–ITO anode) through simple aqueous fabrication, facilitating not only energy level alignment to photoactive blends but also mitigating parasitic absorption and charge recombination losses of the corresponding OSCs. As a result, OSCs and modules consisting of InCl3–ITO anodes achieve remarkable power conversion efficiencies (PCEs) of 18.92% and 15.20% (active area of 18.73 cm2), respectively. More importantly, the InCl3–ITO anode can significantly extend the thermal stability of derived OSCs, with an extrapolated T80 lifetime of ≈10 000 h.

AbstractElectret materials are promising dielectric materials with trapped charges for various applications such as vibration energy harvesters and acoustic transducers. In the present work, ionization potential is discovered as the descriptor to quantify the charging performance for amorphous fluorinated polymer electrets. Using this descriptor, high‐throughput computations, and graph neural network models, 1 176 591 functional groups are screened on the cyclic transparent optical polymers (CYTOP), and 3 promising electrets are identified. The electrets are synthesized experimentally as 15 µm‐thick films. The films are able to keep their both bipolar surface potentials above ±3.1 kV for over 1500 h and are estimated to have longevity of 146 years under 80 °C, achieving significant improvements on charging stability among CYTOP‐based polymer electrets. The excellent bipolar charging performance can greatly enhance power generation capacity of electret‐based vibration energy harvesters. This work also demonstrates the use of deep learning as a new paradigm for accelerating practical materials discovery.

AbstractThin‐film solar cells are expected to play a significant role in the space industry, building integrated photovoltaic (BIPV), indoor applications, and tandem solar cells, where bifaciality and semitransparency are highly desired. Sb2(S,Se)3 has emerged as a promising new photovoltaic (PV) material for its high absorption coefficient, tunable bandgap, and nontoxic and earth‐abundant constituents. However, high‐efficiency Sb2(S,Se)3 solar cells exclusively employ monofacial architectures, leaving a considerable gap toward large‐scale application in aforementioned fields. Here, a bifacial and semitransparent Sb2(S,Se)3 solar cell and its extended application in tandem solar cells are reported. The transparent conductive oxides (TCOs) and the ultrathin inner n–i–p structure provide high long‐wavelength transmittance. Despite the MnS/ITO Schottky junction, power conversion efficiencies (PCEs) of 7.41% and 6.36% are achieved with front and rear illumination, respectively, contributing to a great bifaciality of 0.86. Consequently, the reported device gains great enhancement in PV performance by exploiting albedo of surroundings and shows exceptional capability in absorbing tilt incident light. Moreover, an Sb2(S,Se)3/Si tandem solar cell with a PCE of 11.66% is achieved in preliminary trials. These exciting findings imply that bifacial and semitransparent Sb2(S,Se)3 solar cells possess tremendous potential in practical applications based on their unique characteristics.

AbstractSolar cells formed by spin‐coating organic absorber layers on silicon have attracted widespread attention due to their simple processes and high photovoltaic conversion efficiency (PCE). In typical organic/Si solar cells, however, surface defects or unsatisfactory carrier separation are inadequate to yield excellent device performance. Here, the Au@MoS2 nanocomposites are well synthesized and doped into the organic layer of poly (3,4‐ethylenedioxythiophene)/polystyrene sulfonate (PEDOT:PSS) to improve its work function and the performance of PEDOT:PSS/Si HSCs consequently. By optimizing the doping level of Au@MoS2, the PCE significantly improved from 11.48% to 14.0% by tuning the work function of the PEDOT:PSS layer to more appropriate values. The calculated results based on the Mott–Schottky model indicate that the built‐in field in the PEDOT:PSS/Si interface of HSCs is significantly enhanced due to the increase of work function by the PEDOT:PSS thin films. The enhancement of the built‐in field results in the reduction of the electron–hole recombination loss effectively. The work provides a feasible method for preparing high‐performance PEDOT:PSS/Si HSCs.

AbstractStructural chirality has been imposed onto nano‐alloys to introduce diverse new properties. Chiral nanoparticles (CNPs) with the atomic scale chirality are composed of metastable chiral lattices having low thermal stability, so multielementary (>2 elements) CNPs are very challenging to produce using traditional high‐energy fabrication methods. Herein, layer‐by‐layer glancing angle deposition (LbL‐GLAD) at a low substrate temperature of ≈−40 °C, consisting of GLAD of the host CNPs and the subsequent GLAD of guests, is devised to extend the alloy compositional space to the ternary (e.g., Ag:Al:Cu and Ag:Al:Au) and quaternary (e.g., Ag:Al:Cu:Au and Al:In:Sn:Ti). The low‐temperature GLAD‐induced alloying facilitates the formation of the metastable multi‐layer chiral twisting of achiral facets, chiral defects due to the diffusion of the guests, and chiral electronic bands, leading to a significant amplification of chiroplasmonic optical activities in 20–30 folds. The LbL‐GLAD can be generally adapted to fabricate multielementary alloy CNPs composed of a wide range of elements, with a prospective application of asymmetric catalysts to synthesize an enantiomer with designable chirality, one of the most important topics in modern chemistry and biochemistry to solve the problems of health and environmental pollution.

Published: July 2023

AbstractNear‐band‐edge emissions ranging from red (≈630 to 602 nm) to green (≈550 to 534 nm) and blue (≈494 to 480 nm) colors have been detected in full‐series GaSe1‐xSx (0≤x≤1) multilayers using micro‐photoluminescence (µPL) measurements from 4 to 300 K. The multilayered chalcogenides crystallize in a hexagonal structure, with observed mixed stacking phases of ε and β polymorphs through X‐ray diffraction and Raman measurements. The µPL results, along with experimental band‐edge characterization through thermoreflectance, identify the ε‐stacked phase as the crucial phase responsible for direct recombination and the emission of free excitons within the visible range. A mixed‐color white light is created by PL, which is emitted from the layered GaSe1‐xSx series of different colors, and is positioned at the center of the CIE coordination plot (i.e., white color). To assess the emission properties of both band edges and defects in the layered compounds, time‐resolved photoluminescence (TRPL) is employed, using an area mapping function. The photoluminescence decay lifetime increases as the sulfur content is increased, owing to the greater occurrence of mixed‐phase stacking faults near the β‐GaS end within the GaSe1‐xSx (0≤x≤1) series. The multilayer GaSe1‐xSx (0≤x≤1) represents a distinct 2D chalcogenide series well‐suited for emitting full‐color visible light.

AbstractNephrotoxicity has become prominent due to the increase in the clinical use of nilotinib, a second‐generation BCR‐ABL1 inhibitor in the first‐line treatment of Philadelphia chromosome‐positive chronic myeloid leukemia. To date, the mechanism of nilotinib nephrotoxicity is still unknown, leading to a lack of clinical intervention strategies. Here, it is found that nilotinib could induce glomerular atrophy, renal tubular degeneration, and kidney fibrosis in an animal model. Mechanistically, nilotinib induces intrinsic apoptosis by specifically reducing the level of BCL2 like 1 (Bcl‐XL) in both vascular endothelial cells and renal tubular epithelial cells, as well as in vivo. It is confirmed that chloroquine (CQ) intervenes with nilotinib‐induced apoptosis and improves mitochondrial integrity, reactive oxygen species accumulation, and DNA damage by reversing the decreased Bcl‐XL. The intervention effect is dependent on the alleviation of the nilotinib‐induced reduction in ubiquitin specific peptidase 13 (USP13) and does not rely on autophagy inhibition. Additionally, it is found that USP13 abrogates cell apoptosis by preventing excessive ubiquitin‒proteasome degradation of Bcl‐XL. In conclusion, the research reveals the molecular mechanism of nilotinib's nephrotoxicity, highlighting USP13 as an important regulator of Bcl‐XL stability in determining cell fate, and provides CQ analogs as a clinical intervention strategy for nilotinib's nephrotoxicity.

AbstractAttaining compact energy storage under extreme temperature conditions is of paramount importance in the development of advanced dielectric materials. The polymer composite approach has proved effective towards this goal, and addressing the correlation between filler distribution and electrical properties is foremost in designing composite dielectrics, especially in multifiller systems. Here, the design of a bi‐gradient polymer composite dielectric using an integrated framework based on the phase field model is reported. This framework can predict the charge‐inhibiting behavior of composite dielectrics, which is a key factor impacting the high‐temperature capacitive performance but unfortunately is ignored in conventional phase field models. It is found that due to the traps provided by the functional organic fillers, more carriers are trapped near the electrodes and weaken the electric field, thus significantly suppressing the breakdown initialization process. An interpenetrating gradient structure is designed rationally and synthesized experimentally, which exhibits concurrent high energy density (5.51 J cm−3) and high charge‐discharge efficiency (90%) up to 200 °C. This work provides a strategy to predict the high‐temperature energy storage performance of polymer composites containing charge‐inhibiting components and helps broaden the scope of data‐driven materials design based on phase‐field modeling.
Mechanical Seed Mechanism to Facilitate Homogeneous Li Metal Growth

Published: July 2023

AbstractAn intriguing mechanical seed (MS) concept that modulates (in)homogeneous Li metal growth is proposed based on an in‐depth understanding of its fundamental mechanism using unified atomistic computations. A large dataset of thermodynamic energies for Li disordered phase decouples the dual‐body interactions into three components: i) crystal‐like, ii) long, and iii) short bonds of Li─Li based on machine learning assisted by density function theory calculations. The contributions of these dual‐body interactions offer a mechanical factor for controlling the disordered‐ordered phase transition during electrochemical deposition. Macroscopic molecular dynamics simulations systematically construct the core–shell sphere and cross‐sectional models to reinforce the MS premise. The former reveals that the lower energy level of disordered phase under the moderate compression causes a slow phase kinetics, whereas the strain‐free mode exhibits a relatively fast transition. In addition, the cross‐sectional model exhibits a smooth surface landscape for the strain‐optimized case. These observations are attributed to the surface area evolutions depending on the MS conditions and elucidate the dynamic atomic displacements near the grain boundary from a local structural perspective. The proposed mechanical design concept facilitates uniform Li growth and is expected to be a global parameter in harnessing the full potential of Li metal batteries.
