AbstractEfficient storage and separation of holes and electrons pose significant challenges for catalytic reactions, particularly in the context of single‐phase catalysis. Herein, V2C MXene, with its intrinsic polarized electric field, successfully overcomes this obstacle. To enhance hole storage, a multistep etching process is employed under reducing conditions to control the content of surface termination groups, thus exposing more defective active sites. The intrinsically polarized electric field confines holes to the surface of the layer and free electrons within the layer, leading to a lag in e− release compared to h+. The quantities of stored holes and electrons are measured to be 18.13 µmol g−1 and 106.37 µmol g−1, respectively. Under dark, V2C demonstrates excellent and stable dark‐catalytic performance, degrading 57.91% of tetracycline (TC 40 mg L−1) and removing 23% of total organic carbon (TOC) after 140 min. In simulated sunlight and near‐infrared light, the corresponding degradation rates reach 72.24% and 79.54%, with corresponding TOC removal rates of 49% and 48%, respectively. The hole and electron induced localized surface plasmon resonance (LSPR) effects contribute to a long‐lasting and enhanced broad‐spectrum mineralization of V2C MXene. This study provides valuable insights into the research and application of all‐weather MXene energy storage catalytic materials.

AbstractSimultaneously achieving high efficiency and robust device stability remains a significant challenge for organic solar cells (OSCs). Solving this challenge is highly dependent on the film morphology of the bulk heterojunction (BHJ) photoactive blends; however, there is a lack of rational control strategy. Herein, it is shown that the molecular crystallinity and nanomorphology of nonfullerene‐based BHJ can be effectively controlled by a squaraine‐based doping strategy, leading to an increase in device efficiency from 17.26% to 18.5% when doping 2 wt% squaraine into the PBDB‐TF:BTP‐eC9:PC71BM ternary BHJ. The efficiency is further improved to 19.11% (certified 19.06%) using an indium‐tin‐oxide‐free column‐patterned microcavity (CPM) architecture. Combined with interfacial modification, CPM quaternary OSC excitingly shows an extrapolated lifetime of ≈23 years based on accelerated aging test, with the mechanism behind enhanced stability well studied. Furthermore, a flexible OSC module with a high and stable efficiency of 15.2% and an overall area of 5 cm2 is successfully fabricated, exhibiting a high average output power for wearable electronics. This work demonstrates that OSCs with new design of BHJ and device architecture are highly promising to be practical relevance with excellent performance and stability.

AbstractNonaqueous Li‐O2 battery (LOB) represents one of the promising next‐gen energy storage solutions owing to its ultrahigh energy density but suffers from problems such as high charging overpotential, slow redox kinetics, Li anode corrosion, etc., calling for a systemic optimization of the battery configuration and structural components. Herein, an ingenious “trinity” design of LOB is initiated by implementing a hollowed cobalt metal organic framework (MOF) impregnating iodized polypyrrole simultaneously as the cathode catalyst, anode protection layer, and slow‐release capsule of redox mediators, so as to systemically address issues of impeded mass transport and redox kinetics on the cathode, dendrite growth, and surface corrosion on the anode, as well as limited intermediate solubility in the low donor‐number (DN) solvent. As a result of the systemic effort, the LOB constructed demonstrates an ultralow discharge/charge polarization of 0.2 V, prolonged cycle life of 1244 h and total discharge capacity of 28.41 mAh cm−2. Mechanistic investigations attribute the superb LOB performance to the redox‐mediated solution growth mechanism of crystalline Li2O2 with both enhanced reaction kinetics and reversibility. This study offers a paradigm in designing smart materials to raise the performance bar of Li‐O2 battery toward realistic applications.

Published: October 2023

AbstractThe air electrode is an essential component of air‐demanding energy storage/conversion devices, such as zinc–air batteries (ZABs) and hydrogen fuel cells (HFCs), which determines the output power and stability of the devices. Despite atom‐level modulation in catalyst design being recently achieved, the air electrodes have received much less attention, causing a stagnation in the development of air‐demanding equipment. Herein, the evolution of air electrodes for ZABs and HFCs from the early stages to current requirements is reviewed. In addition, the operation mechanism and the corresponding electrocatalytic mechanisms of ZABs are summarized. In particular, by clarifying the air electrode interfaces of ZABs at different scales, several approaches to improve the air electrode in rechargeable ZABs are reviewed, including innovative electrode structures and bifunctional oxygen catalysts. Afterward, the operating mechanisms of proton‐exchange‐membrane fuel cells (PEMFCs) and anion‐exchange‐membrane fuel cells (AEMFCs) are explained. Subsequently, the strategies employed to enhance the efficiency of the membrane electrode assembly (MEA) in PEMFCs and AEMFCs, respectively, are highlighted and discussed in detail. Last, the prospects for air electrodes in ZABs and HFCs are considered by discussing the main challenges. The aim of this review is to facilitate the industrialization of ZABs and HFCs.

AbstractOrganic–inorganic halide perovskites (OIHPs) show high promise in optical and electronic applications such as solar cells, light‐emitting diodes, and nonlinear optics. However, the fundamental knowledge of the atomic‐scale microstructures in OIHP thin films is limited due to the challenge in characterizing them using transmission electron microscopy (TEM). Here a solution‐phase “release‐and‐transfer” method is demonstrated, which entails the lifting of OIHP films from their original substrates while maintaining the film integrity, followed by a sequential transfer onto a TEM grid. The freestanding nature of the OIHP films with a nanoscale thickness, prepared as such, allows a direct TEM observation in the plan view, complementing those typical cross‐sectional views enabled by focus‐ion‐beam specimen fabrication. Using low‐dose scanning TEM, the atomic‐scale microstructure of transferred OIHP films is confirmed to be generally maintained, while the microstrain existing in original films is largely relaxed. This “release‐and‐transfer” method is generic to both standard 3D and low‐dimensional OIHPs. Based on a simple layer‐by‐layer transfer, the fabrication of a 2D–3D planar heterojunction with a good interfacial contact and optoelectronic properties is achieved. This unique methodology offers new opportunities to accelerate the fundamental and practical developments of OIHP materials and devices.

Published: October 2023

AbstractHerein, we report a protocol for the selective δ‐thiolation of aliphatic α‐amino acids catalyzed by a Pd(II)/Ag(I) system. This reaction employs disulfides as thiolating agents and N‐COPy as directing group, providing valuable non‐proteinogenic amino acid derivatives in moderate to good diastereoselectivities and yields. Remarkably, the method is also suitable for the late‐stage functionalization of a dipeptide. Experimental and DFT studies have provided significant insights into the mechanism and underlying factors controlling the selectivity of the process and determining the key role of the silver salt.

AbstractImmunotherapy has recently emerged as the predominant therapeutic approach for cervical cancer (CCa), driven by the groundbreaking clinical achievements of immune checkpoint inhibitors (ICIs), such as anti‐PD‐1/PD‐L1 antibodies. N4‐acetylcytidine (ac4C) modification, catalyzed by NAT10, is an important posttranscriptional modification of mRNA in cancers. However, its impact on immunological dysregulation and the tumor immunotherapy response in CCa remains enigmatic. Here, a significant increase in NAT10 expression in CCa tissues is initially observed that is clinically associated with poor prognosis. Subsequently, it is found that HOXC8 activated NAT10 by binding to its promoter, thereby stimulating ac4C modification of FOXP1 mRNA and enhancing its translation efficiency, eventually leading to induction of GLUT4 and KHK expression. Moreover, NAT10/ac4C/FOXP1 axis activity resulted in increased glycolysis and a continuous increase in lactic acid secretion by CCa cells. The lactic acid‐enriched tumor microenvironment (TME) further contributed to amplifying the immunosuppressive properties of tumor‐infiltrating regulatory T cells (Tregs). Impressively, NAT10 knockdown enhanced the efficacy of PD‐L1 blockade‐mediated tumor regression in vivo. Taken together, the findings revealed the oncogenic role of NAT10 in initiating crosstalk between cancer cell glycolysis and immunosuppression, which can be a target for synergistic PD‐1/PD‐L1 blockade immunotherapy in CCa.

AbstractDisrupting intracellular redox homeostasis combined with immune checkpoint blockade therapy is considered as an effective way to accelerate tumor cell death. However, suppressed tumor immune microenvironment and lower cargo delivery restrict the efficiency of tumor therapy. In this study, a multifunctional tumor microenvironment (TME)‐responsive nanocomposite is constructed using manganese tetroxide (Mn3O4)‐decorated disulfide‐bond‐incorporated dendritic mesoporous organosilica nanoparticles (DMONs) to co‐deliver indoleamine 2,3‐dioxygenase (IDO) inhibitor Epacadostat (IDOi) and glucose oxidase (GOx) following modification with polyethylene glycol. Owing to the responsiveness of Mn3O4‐decorated DMONs to the mildly acidic and glutathione (GSH) overexpressed TME, the nanocomposite can rapidly decompose and release inner contents, thus substantially improving the cargo release ability. Mn3O4 can effectively catalyze hydrogen peroxide (H2O2) decomposition to generate oxygen, enhance the ability of GOx to consume glucose to produce H2O2, and further promote the generation of hydroxyl radicals (•OH) by Mn2+. Furthermore, Mn2+‐mediated GSH depletion and the production of •OH can disrupt intracellular redox homeostasis, contributing to immunogenic cell death. Simultaneously, IDOi can inhibit IDO to reverse inhibited immune response. The results show that self‐amplifying chemodynamic/starvation therapy combined IDO‐blockade immunotherapy synergistically inhibits tumor growth and metastasis in vivo.

AbstractGrip strength is a biomarker of frailty and an evaluation indicator of brain health, cardiovascular morbidity, and psychological health. Yet, the development of a reliable, interactive, and point‐of‐care device for comprehensive multi‐sensing of hand grip status is challenging. Here, a relation between soft buckling metamaterial deformations and built piezoelectric voltage signals is uncovered to achieve multiple sensing of maximal grip force, grip speed, grip impulse, and endurance indicators. A metamaterial computational sensor design is established by hyperelastic model that governs the mechanical characterization, machine learning models for computational sensing, and graphical user interface to provide visual cues. A exemplify grip measurement for left and right hands of seven elderly campus workers is conducted. By taking indicators of grip status as input parameters, human‐computer interactive games are incorporated into the computational sensor to improve the user compliance with measurement protocols. Two elderly female schizophrenic patients are participated in the real‐time interactive point‐of‐care grip assessment and training for potentially sarcopenia screening. The attractive features of this advanced intelligent metamaterial computational sensing system are crucial to establish a point‐of‐care biomechanical platform and advancing the human‐computer interactive healthcare, ultimately contributing to a global health ecosystem.

AbstractGreen hydrogen production is emerging as an essential task for future energy. Water splitting is an effective approach to yield green hydrogen with high purity. However, expensive electrocatalysts are required that can increase the production cost. Herein, a novel procedure is proposed to incorporate iridium single atoms into zirconium‐doped pure‐phase cobalt phosphide (Ir@Zr–CoP) that can adjust the electronic properties and enhance the electrochemical active sites. When Ir@Zr–CoP serves as a bifunctional catalyst for the hydrogen evolution reaction (HER) and the oxygen evolution reaction (OER), it requires a low overpotential of 74 and 292 mV to accomplish a current density of 10 mA cm−2. Remarkably, when the Ir@Zr–CoP based electrode is assembled as a large‐scalable anion‐exchange membrane water electrolyzer, the device requires a small cell voltage of only 1.88 V to obtain a current density of 1.0 A cm−2 with high stability for 150 h.

Published: October 2023

AbstractCu2ZnSn(S,Se)4 (CZTSSe) solar cells, composed of earth‐abundant materials, face challenges in achieving high power conversion efficiency (PCE) due to non‐radiative recombination. The limitations primarily stem from the prevalence of CuZn‐related and SnZn‐related defects in the bulk of the absorber and at the heterojunction interface region. To overcome these challenges, a dual treatment approach is proposed that involves Ag‐alloying in the bulk and Al2O3 atomic layer deposition (ALD) process at the p–n interface. Comprehensive characterizations of the fabricated devices reveal that Ag‐alloying leads to a substantial reduction in deep defects within the bulk, while Al2O3 ALD process facilitates the formation of a well‐defined p–n interface region, along with the defect passivation. This synergetic effect enables PCE enhancement accompanied by the improvements of all device parameters. Notably, devices subjected to the additional Al2O3 ALD process exhibit a substantial improvement in fill factor, which is found to be consistent with a reduced element intermixing width at the p–n heterojunction region. Due to improvements in both the bulk absorber and the heterojunction, the highest PCE of 13.33% is achieved without an anti‐reflection coating.

Published: October 2023

AbstractThe electroreduction of nitrate into green ammonia (NO3−‐to‐NH3) in aqueous solution represents a sustainable route applicable to green NH3 electrosynthesis and nitrogen balance. However, the NO3−‐to‐NH3 electroreduction undergoes a complex eight electron (8e−) transfer pathway and results in unsatisfying activity and selectivity. Here, mesostructures engineering is presented as a new and robust design strategy for producing high‐performance multimetallic electrocatalysts that remarkably promote selective NO3−‐to‐NH3 electroreduction. 1D PdCuAg mesoporous nanotubes (MTs) are facilely prepared by a one‐step galvanic replacement‐assisted surfactant‐templating method in an aqueous solution. The electrocatalyst shows remarkable NO3−‐to‐NH3 performance with high NH3 Faradaic efficiency (FENH3) of 95.2%, superior NH3 yield rate of 17.7 mg h−1 mg−1, impressive NH3 energy efficiency of 29.8%, and outstanding stability (50 cycles), all of which are much better than the performance of counterpart electrocatalysts. The promotion of NO3−‐to‐NH3 performance comes from the electron‐rich surface and nanoconfinement microenvironment of mesostructured synergies that enrich nanozyme‐like chemisorption of key intermediates and thus facilitates electroreduction of NO3− into NH3 through an 8e− reaction pathway. Meanwhile,1D PdCuAg MTs are practically explored in a Zn‐NO3− battery, delivering a superior NH3 yield rate of 25.85 µmol h−1 cm−2 and a high FENH3 of 92.4%.
Learning to balance wheat G × E × M interactions in response to a changing climate—The case for ultra‐early planting systems
Authors: Collier Graham R. S. , Spaner Dean M. , Beres Brian L. 
Published: October 2023

AbstractReported global reductions in cereal grain yields due to increased global average temperature combined with increasing global populations peaking near 2050 create an immediate need to increase cereal grain yield potential and reduce the yield gap between realized on‐farm grain yield and potential yield. The development of an ultra‐early planting system for spring wheat (Triticum aestivum L.) on the northern Great Plains can increase the resiliency of current growing systems to a changing climate. This was achieved through the development of a unique set of practices designed to successfully shift current wheat production systems to ultra‐early growing systems. Ultra‐early‐planted wheat‐growing systems on the northern Great Plains will provide immediate benefits to the adopting producer in the form of increased grain yield and increased grain yield stability relative to current practices. As global average temperatures warm, and atmospheric CO2 concentrations increase, the northern Great Plains region is in a unique position to potentially realize grain yield increases rather than temperature‐driven grain yield decreases. Shifting planting earlier and taking advantage of increased growing degree day accumulation and water use efficiencies while avoiding higher temperatures during sensitive physiological periods are tactics implemented in ultra‐early growing systems that will increase in importance and relevance in the next three decades as average daily temperatures increase.
Does nutrition knowledge training improve dietary diversity and nutrition intake? Insights from rural China

Published: October 2023

AbstractImproving dietary diversity and nutrition intake among rural households is essential to promote sustainable rural development. In this study, we examine whether nutrition knowledge training increases rural households' dietary diversity, nutrition intake, and total calorie intake. We consider three macronutrients (proteins, fats, and carbohydrates) and three micronutrients (vitamin C, iron, and zinc) to capture nutrition intake. The doubly robust inverse probability weighted regression adjustment estimator is employed to estimate survey data of 765 rural households collected by the Institute of Food and Nutrition Development, Ministry of Agriculture and Rural Affairs of China. The results show that nutrition knowledge training enhances household dietary diversity, improves the intake of macronutrients in terms of proteins and fats and micronutrients in terms of zinc, and increases total calorie intake. In addition, the intake of nutrients and calories of males responds to nutrition knowledge training while that of females does not. The dietary diversity of females increases with nutrition knowledge training, whereas that of males is unaffected. {EconLit Citations: I12, I18, Q12, E24}.
