AbstractUsing a combinatory blending strategy is demonstrated as a promising path for designing efficient organic solar cells (OSCs) by boosting the short‐circuit current density and fill factor. Herein, a high‐performance ternary all‐small molecule OSC (all‐SMOSCs) using a narrow‐bandgap alloy acceptor containing symmetric and asymmetric molecules (BTP‐eC9 and SSe‐NIC) and a wide‐bandgap small molecule donor MPhS‐C2 is reported. Introducing the synthesized SSe‐NIC into the MPhS‐C2:BTP‐eC9 host system can broaden the absorption spectrum, modulate energy offsets, and optimize the molecular packing of the host materials. After systematically optimizing the weight ratio of MPhS‐C2:BTP‐eC9:SSe‐NIC, a champion efficiency of 18.02% is achieved. Impressively, the ternary system not only delivered a broad composition tolerance with device efficiencies over 17% throughout the whole blend ratios, but also exhibited less non‐geminate recombination and energy loss, and better‐light‐soaking stability than the corresponding binary systems. This work promotes the development of high‐performance ternary all‐SMOSCs and heralds their brighter application prospects.

AbstractRuthenium chalcogenide is a highly promising catalytic system as a Pt alternative for hydrogen evolution reaction (HER). However, well‐studied ruthenium selenide (RuSe2) still exhibits sluggish HER kinetics in alkaline media due to the inappropriate adsorption strength of H and H2O. Herein, xx report a new design of Cu‐doped Ru/RuSe2 heterogeneous nanosheets (NSs) with optimized H and H2O adsorption strength for highly efficient HER catalysis in alkaline media. Theoretical calculations reveal that the superior HER performance is attributed to a synergistic effect of the unique heterointerfaced structure and Cu doping, which not only optimizes the electronic structure with a suitable d‐band center to suppress proton overbinding but also alleviates the energy barrier with enhanced H2O adsorption. As a result, Cu‐doped heterogeneous Ru/RuSe2 NSs exhibit a small overpotential of 23 mV at 10 mA cm−2, a low Tafel slope of 58.5 mV dec−1 and a high turnover frequency (TOF) value of 0.88 s−1 at 100 mV for HER in alkaline media, which is among the best catalysts in noble metal‐based electrocatalysts toward HER. The present Cu‐doped Ru/RuSe2 NSs interface catalyst is very stable for HER by showing no activity decay after 5000‐cycle potential sweeps. This work heralds that heterogeneous interface modulation opens up a new strategy for the designing of more efficient electrocatalysts.

AbstractScintillators, one of the essential components in medical imaging and security checking devices, rely heavily on rare‐earth‐containing inorganic materials. Here, a new type of organic‐inorganic hybrid scintillators containing earth abundant elements that can be prepared via low‐temperature processes is reported. With room temperature co‐crystallization of an aggregation‐induced emission (AIE) organic halide, 4‐(4‐(diphenylamino) phenyl)‐1‐(propyl)‐pyrindin‐1ium bromide (TPA‐PBr), and a metal halide, zinc bromide (ZnBr2), a zero‐dimensional (0D) organic metal halide hybrid (TPA‐P)2ZnBr4 with a yellowish‐green emission peaked at 550 nm has been developed. In this hybrid material, dramatically enhanced X‐ray scintillation of TPA‐P+ is achieved via the sensitization by ZnBr42−. The absolute light yield (14,700 ± 800 Photons/MeV) of (TPA‐P)2ZnBr4 is found to be higher than that of anthracene (≈13,500 Photons/MeV), a well‐known organic scintillator, while its X‐ray absorption is comparable to those of inorganic scintillators. With TPA‐P+ as an emitting center, short photoluminescence and radioluminescence decay lifetimes of 3.56 and 9.96 ns have been achieved. Taking the advantages of high X‐ray absorption of metal halides and efficient radioluminescence with short decay lifetimes of organic cations, the material design paves a new pathway to address the issues of low X‐ray absorption of organic scintillators and long decay lifetimes of inorganic scintillators simultaneously.

AbstractWith the overconsumption of disposable plastics, there is a considerable emphasis on the recycling of waste plastics to relieve the environmental, economic, and health‐related consequences. Here, a sulfur‐assisted pyrolysis strategy is demonstrated for versatile upcycling of plastics into high‐value carbons with an ultrahigh carbon‐atom recovery (up to 85%). During the pyrolysis process, the inexpensive elemental sulfur molecules are covalently bonded with polymer chains, and then thermally stable intermediates are produced via dehydrogenation and crosslinking, thereby inhibiting the decomposition of plastics into volatile small hydrocarbons. In this manner, the carbon products obtained from real‐world waste plastics exhibit sulfur‐rich skeletons with an enlarged interlayer distance, and demonstrate superior sodium storage performance. It is believed that the present results offer a new solution to alleviate plastic pollution and reduce the carbon footprint of plastic industry.

Published: March 2023

AbstractMetal oxide‐based catalysts are widely studied in oxidative propane dehydrogenation (OPDH), but they usually suffered from the low olefin activity, which is believed to be related to the active centers of metal‐oxygen species. Herein, we report an effective cation‐exchange strategy towards the development of TiO2nanosheets embedded isolated Fe species (Fe1TiO2) as a highly‐active and stable catalyst for OPDH. It exhibits an olefin yield of 38.2% at 520°C, 10.9 and 2.4 times higher than that of pure TiO2(3.5%) and Fe2O3(15.6%), respectively; and it shows a superior 100‐h durability. The isolated Fe species embedded in Fe1TiO2are demonstrated to serve as active centers. Multiple characterizations includingin situFourier transform infrared spectroscopy (FT‐IR) and theoretical calculations demonstrate that the isolated Fe species in Fe1TiO2are favorable for the generation of olefins, which produce propylene (C3) through an appropriate FeH dehydrogenation pathway with a low energy barrier.

AbstractTo increase the red blood cell (RBC) cryopreservation efficiency by metal–organic frameworks (MOFs), a dimensional reduction approach has been proposed. Namely, 3D MOF nanoparticles are progressively reduced to 2D ultra‐thin metal–organic layers (MOLs). We found that 2D MOLs are beneficial for enhanced interactions of the interfacial hydrogen‐bonded water network and increased utilization of inner ordered structures, due to the higher surface‐to‐volume ratio. Specifically, a series of hafnium (Hf)‐based 2D MOLs with different thicknesses (monolayer to stacked multilayers) and densities of hydrogen bonding sites have been synthesized. Both ice recrystallization inhibition activity (IRI) and RBCs cryopreservation assay confirm the pronounced better IRI activity and excellent cell recovery efficiency (up to ≈63 % at a very low concentration of 0.7 mg mL−1) of thin‐layered Hf‐MOLs compared to their 3D counterparts, thereby verifying the dimensional reduction strategy to improved cryoprotectant behaviors.

AbstractThe use of visible light to drive polymerizations with spatiotemporal control offers a mild alternative to contemporary UV‐light‐based production of soft materials. In this spectral region, photoredox catalysis represents the most efficient polymerization method, yet it relies on the use of heavy‐atoms, such as precious metals or toxic halogens. Herein, spin‐orbit charge transfer intersystem crossing from boron dipyrromethene (BODIPY) dyads bearing twisted aromatic groups is shown to enable efficient visible light polymerizations in the absence of heavy‐atoms. A ≈5–15× increase in polymerization rate and improved photostability was achieved for twisted BODIPYs relative to controls. Furthermore, monomer polarity had a distinct effect on polymerization rate, which was attributed to charge transfer stabilization based on ultrafast transient absorption and phosphorescence spectroscopies. Finally, rapid and high‐resolution 3D printing with a green LED was demonstrated using the present photosystem.

AbstractDeveloping a novel tool capable of real‐time monitoring and simultaneously quantifying of both intra/extracellular chemical signals across the large‐scale brain is the key bottleneck for understanding the interactions between the molecules inside and outside neurons. Here we built up a high‐density intra/extracellular optophysiology platform, together with developing two probes for specific recognition of L‐cysteine (Cys) and dopamine (DA), for simultaneously quantifying of both intracellular Cys and extracellular DA with high selectivity and accuracy across the brain of freely moving animals, as well as recording electrical signals. Using this powerful tool, it was found that intracellular Cys regulated extracellular DA through inducing the expression of tyrosine hydroxylase in the depressed mice brain. We also established the functional networks of Cys and DA across 32 brain regions in freely moving animals. More importantly, it was discovered that depression reduced the correlations between adjacent brain regions, which was recovered by the treatment of N‐acetyl‐l‐cysteine.
Electron Redistribution Enables Redox‐Resistible Li6PS5Cl towards High‐Performance All‐Solid‐State Lithium Batteries

Published: March 2023

AbstractSulfide electrolytes with high ionic conductivity hold great promise for all‐solid‐state lithium batteries. However, the parasitic redox reactions between sulfide electrolyte and Li metal result in interfacial instability and rapid decline of the battery performance. Herein, a redox‐resistible Li6PS5Cl (LPSC) electrolyte is created by regulating the electron distribution in LPSC with Mg and F incorporation. The introduction of Mg triggers the electron agglomeration around S atom, inhibiting the electron acceptance from Li, and F generates the self‐limiting interface, which hinders the redox reactions between LPSC and Li metal. This redox‐resistible Li6PS5Cl‐MgF2 electrolyte therefore presents a high critical current density (2.3 times that of pristine electrolyte). The LiCoO2/Li6PS5Cl‐MgF2/Li cell shows an outstanding cycling stability (93.3 %@100 cycles at 0.2 C). This study highlights the electronic structure modulation to address redox issues on sulfide‐based lithium batteries.

Published: March 2023

AbstractThis paper investigates a local observer‐based leader‐following consensus control of one‐sided Lipschitz (OSL) multi‐agent systems (MASs) under input saturation. The proposed consensus control scheme has been formulated by using the OSL property, input saturation, directed graphs, estimated states, and quadratic inner‐boundedness condition by attaining the regional stability. It is assumed that the graph always includes a (directed) spanning tree with respect to the leader root to develop matrix inequalities for investigating parameters of the proposed observer and consensus protocols. Further, a new observer‐based consensus tracking method for MASs with saturation, concerning independent topologies for communicating outputs and estimates over the network, is explored to deal with a more perplexing and realistic situation. In contrast to the traditional methods, the proposed consensus approach considers output feedback and deals with the input saturation for a generalized class of nonlinear systems. The efficiency of the obtained results is illustrated via application to a group of five moving agents in the Cartesian coordinates.

AbstractXMM‐Newton, a European Space Agency observatory, has been observing the X‐ray, ultra‐violet, and optical sky for 23 years. During this time, astronomy has evolved from mainly studying single sources to populations and from a single wavelength, to multi‐wavelength/messenger data. We are also moving into an era of time domain astronomy. New software and methods are required to accompany evolving astronomy and prepare for the next‐generation X‐ray observatory, Athena. Here we present XMM2ATHENA, a program funded by the European Union's Horizon 2020 research and innovation program. XMM2ATHENA builds on foundations laid by the XMM‐Newton Survey Science Centre (XMM‐SSC), including key members of this consortium and the Athena Science ground segment, along with members of the X‐ray community. The project is developing and testing new methods and software to allow the community to follow the X‐ray transient sky in quasi‐real time, identify multi‐wavelength/messenger counterparts of XMM‐Newton sources and determine their nature using machine learning. We detail here the first milestone delivery of the project, a new online, sensitivity estimator. We also outline other products, including the forthcoming innovative stacking procedure and detection algorithms, to detect the faintest sources. These tools will then be adapted for Athena and the newly detected/identified sources will enhance preparation for observing the Athena X‐ray sky.

Published: March 2023

AbstractIntracellular zinc ions are essential for various biological cell processes and are often dysregulated in many diseases de‐pending on their location, protein binding affinity, and concentration in the cell. Due to their prevalence in diseases, it is important to not only effectively sense but chelate the often excess amount of zinc in a cell to alleviate further disease progression. N, N, N′, N′‐tetrakis (2‐pyridinylmethyl)‐1,2‐ethanediamine (TPEN) is a selective zinc chelator but its water‐insoluble nature and general cytotoxicity limit its therapeutic potential. To address these challenges, TPEN loaded nucleic acid nanocapsules (TL‐NANs) were synthesized, and its dual ability to sense and suppress zinc levels intracellularly were evaluated. Additionally, TL‐NANs were incubated in lung cells and shown to down regulate Eotaxin, a protein up‐regulated during asthma, at significantly reduced concentrations of TPEN showcasing the therapeutic potential of this drug for asthma.

AbstractThe ability of Poa annua L. to adapt to most turfgrass environments extends to its ability to develop resistance to commonly used herbicides. Herbicide resistant P. annua is of almost epidemic proportions. The loss of once viable chemical‐based treatments pushes practitioners towards more expensive, and often less effective, control strategies. This management guide focuses on integrated weed management (IWM) practices for P. annua control and herbicide resistance—what it is and how to overcome it. Also discussed are resistance mechanisms and documentation of common occurrences of field‐level resistance within much of the United States. Finally, a summary of some of the social and economic constraints that practitioners face in the implementation of IWM strategies for P. annua is discussed.

Published: March 2023

AbstractAn efficient domino approach for the synthesis of biologically important 2‐aminoindole derivatives has been developed using CuBr2‐mediated SET oxidative cyclization as a key step. This one‐pot multicomponent strategy utilizes readily available ethyl propiolate, tosyl azide, and substituted aryl amines as starting materials. The generality and scope of this mild method are demonstrated with a wide variety of substrates to furnish functionalized 2‐aminoindoles in good yields. The synthetic power of this strategy is further exemplified in the concise synthesis of biologically important alkaloids, Phaitanthrin E and Tryptanthrin.

AbstractBackgroundPersisting symptoms after concussion (PSaC) include physical, cognitive, and psychological symptoms which contribute to rehabilitation challenges. Previous research has not thoroughly investigated the association between PSaC and pain‐related psychological factors. Therefore, there is an opportunity to use current pain models, such as the Fear Avoidance Model (FAM), as a framework to explore these relationships. The goals of this integrative review are to (1) identify and describe range of evidence that explores relationships between psychological factors and clinical outcomes in patients with PSaC, and (2) develop a comprehensive understanding of FAM‐specific psychological factors that have been identified as potential predictors of clinical outcomes in patients with PSaC.MethodsThis review will be based on principles and stages of an integrative review which will allow for inclusion of diverse methodologies: (1) problem formulation, (2) literature search, (3) data evaluation, (4) data analysis, and (5) presentation. Methods for reporting this review will be informed by the 2020 PRISMA guidelines for systematic reviews.DiscussionThe findings from this integrative review will inform healthcare professionals working in post‐concussion rehabilitation settings regarding relationships between FAM psychological factors and PSaC—an area that until recently has not been thoroughly explored. Additionally, this review will inform the development of other reviews and clinical studies to further investigate relationships between FAM psychological factors and PSaC.Integrative Review RegistrationOSF DOI 10.17605/OSF.IO/CNGPW.
