Published: May 2023

AbstractCavity‐enhanced superfluorescence (CESF) in quantum dot (QD) system is an ultrafast and intense lasing generated by combination of quantum coupling effect and optically stimulated amplification effect, which can provide a new idea for realizing high quality blue light sources and address the limitation of conventional inefficient blue light sources. Modifying halide composition is a straightforward method to achieve blue emission in perovskite QD system. However, the spectral instability introduced by photoinduced halide phase segregation and low coupling efficiency between QDs and optical cavities make it challenging to achieve stable blue CESF in such halide‐doped QD system. Herein, long‐range‐ordered, densely packed CsPbBr2Cl QD‐assembled superlattice microcavities in which the two core issues can be appropriately addressed are developed. The QD superlattice structure facilitates excitonic delocalization to decrease exciton‐phonon coupling, thus alleviating photoinduced phase segregation. By combination of theoretical analysis and temperature‐dependent photoluminescence (PL) measurements, the underlying photoinduced phase segregation mitigation mechanism in mixed halide superlattices is clarified. Based on the CsPbBr2Cl QD superlattices with regularly geometrical structures, in which the gain medium can be strongly coupled to the naturally formed microcavity, stable and ultrafast (3 ps) blue CESF with excellent optical performance (threshold ≈33 µJ cm−2, quality factor ≈1900) is realized.

AbstractThe deposition of high‐quality dielectric films on graphene surfaces is crucial in fabricating high‐performance graphene‐based electronics. In this study, the first application of UV‐assisted atomic layer deposition (UV‐ALD) to graphene surfaces and the fabrication of graphene field‐effect transistors (GFETs) with UV‐ALD Al2O3 dielectric thin films is demonstrated. Optimal UV irradiation (5 s per cycle) during the ALD process results in denser and smoother Al2O3 dielectric films deposited on the graphene surface with the intimate graphene‐dielectric interface, while excessive UV irradiation in turn prohibits the film nucleation. As a result, the GFETs with a high‐quality dielectric layer deposited by UV‐ALD show improved performance with a Dirac voltage close to 0 V and hole mobility of 1221 cm2 V−1 s−1, i.e., > 200% increase compared to those with thermal ALD. This study demonstrates that UV‐ALD is an effective and simple option to realize a high‐quality interface between 2D materials and ultra‐thin dielectric films.

AbstractMXenes are promising substrates for supported noble metal electrocatalysts. Yet, it is a significant challenge to modulate the metal–support interaction (MSI) for enhancing catalytic performance. Herein, employing a facile HF etching method, the cation vacancy structures in Ti3C2Tx MXenes are controllably tuned, producing nearly vacancy‐free (Ti3C2Tx‐V0), single Ti atom vacancy (Ti3C2Tx‐VS), or Ti vacancy cluster (Ti3C2Tx‐VC) engineered MXenes. Ruthenium atomic clusters, as a model catalyst, successfully anchor on all MXene substrates. Different from the terminal O/F coordination groups on routine Ti3C2Tx MXene surfaces, the Ti vacancy clusters in Ti3C2Tx‐VC create unique lattice carbon ligand environment toward Ru species, which induces ultra‐strong MSI. As a result, compared to Ti3C2Tx‐V0 and Ti3C2Tx‐VS, the Ti3C2Tx‐VC modulated Ru clusters (Ru@Ti3C2Tx‐VC) exhibit the optimized balance of H2O adsorption/dissociation and OH/H desorption, thereby delivering superior electrocatalytic performance in the alkaline hydrogen evolution reaction (HER). Within the wide range from laboratory‐level (90 mA cm−2) to industrial‐level (1.5 A cm−2) current density, Ru@Ti3C2Tx‐VC outperforms commercial Pt/C in terms of overpotential and mass activity. Moreover, as a universal substrate for noble metal catalysts, Ti3C2Tx‐VC can also anchor Ir/Pt/Rh atomic clusters and enable excellent HER catalytic activity. This work expands the scope of the MSI between MXene and noble metal catalysts.

AbstractThe development of large‐scale energy storage systems (ESSs) aimed at application in renewable electricity sources and in smart grids is expected to address energy shortage and environmental issues. Sodium‐ion batteries (SIBs) exhibit remarkable potential for large‐scale ESSs because of the high richness and accessibility of sodium reserves. Using low‐cost and abundant elements in cathodes with long cycling stability is preferable for lowering expenses on cathodes. Many investigated cathodes for SIBs are dogged by structural and morphology changes, unstable interphases between the cathode and the electrolyte, and air sensitivity, causing unsatisfactory cycling performance. Therefore, understanding the mechanism of capacity degeneration in depth and developing precise solutions are critical for designing low‐cost cathodes that are highly stable under cycling. Herein, recent progress in long‐cycle‐life and low‐cost cathodes for SIBs is focused on, and a comprehensive discussion of the key points in SIBs toward large‐scale applications is provided. The roots of the unstable cycling performance of low‐cost cathodes are discussed. Also, effective strategies are summarized from the recent progress on long‐cycle‐life and low‐cost cathodes. This review is expected to encourage deeper investigation of long‐lifespan cathodes for SIBs, particularly for potential large‐scale industrialization.

AbstractUnderstanding and eliminating degradation of the electrolyte solution is arguably the major challenge in the development of high energy density lithium–air batteries. The use of acetonitrile provides cycle stability comparable to current state‐of‐the‐art glyme ethers and, while solvent degradation has been extensively studied, no mechanism for acetonitrile degradation has been proposed. Through the application of in situ pressure measurements and ex situ characterization to monitor the degradation of acetonitrile in the lithium–air battery, a correlation between H2O concentration within the cell and deviation from the idealized electron/oxygen ratio is revealed. Characterization of the cycled electrolyte solution identifies acetamide as the major degradation product under both cell and model conditions. A new degradation pathway is proposed that rationalizes the formation of acetamide, identifies the role of H2O in the degradation process, and confirms lithium hydroperoxide as a critical antagonistic species in lithium–air cells for the first time. These studies highlight the importance of considering the impact of atmospheric gases when exploring lithium–air cell chemistry and suggest that further exploration of the impact of hydroperoxide species on the degradation in lithium–air cells may lead to identification of more effective electrolyte solvents.

AbstractInverted (p‐i‐n) perovskite solar cells have drawn great attention due to their outstanding stability and low‐temperature processibility. However, their power conversion efficiency (PCE) still lags behind conventional (n‐i‐p) devices mainly due to the lack of strategies to stabilize α‐FAPbI3 without changing the bandgap. In this work, a facile and effective strategy is reported to regulate the residual strain via pseudo halide‐based ionic liquids incorporation to stabilize α‐FAPbI3 perovskite in inverted perovskite solar cells (PVSCs). The employment of methylamine formate (MAFa) ionic liquid enables a homogenously stronger compressive strain to restrain the transition of shared‐corner PbI6 octahedron into shared‐face δ‐FAPbI3, as well as affecting the dynamic behavior of carriers and defects to achieve a record PCE (24.08%) among the reported inverted FAPbI3 perovskite solar cells up to now. In addition, the MAFa incorporation results in enhanced device stability, unencapsulated PVSC retains over 90% of its initial efficiency after stored in ambient environment (RH:30 ± 5%) for 1000 h. This work provides an efficient strategy to realize efficient and stable α‐FAPbI3 based inverted PVSCs to further catch up with the conventional ones.

AbstractMetal fluoride–lithium batteries with potentially high‐energy densities are regarded as promising candidates for next‐generation low‐cost rechargeable batteries. However, liquid‐electrolyte metal fluoride–lithium batteries suffer from sluggish reaction kinetics, high voltage hysteresis due to side reactions, poor rate capability, and rapid capacity drop during cycling. Moreover, the research on sulfide all‐solid‐state batteries (ASSBs) with metal fluoride cathode is still lacking. Herein, four kinds of iron fluoride materials are applied to the sulfide all‐solid‐state lithium battery system for the first time to investigate the best cathode and corresponding methods. Electrochemical tests showed the cycling performance at different current densities (0.1, 0.3, and 1 C) and rate performance of the four cathodes with the following rules: FeF3‐HT > FeF3‐RT > FeF3·0.33H2O > FeF3·3H2O. The reversible capacities of FeF3‐HT AASB are 519.9 mAh g−1 after 120 cycles at 0.3C and still maintains 340.7 mAh g−1 after 400 cycles even at a high rate of 1 C. In addition, electro impedence spectroscopy and cyclic voltammetry tests of the above four cathodes show that different contents of crystal water, morphologies, and particle sizes have a great influence on the lithium storage mechanism of cathode. Moreover, the reason for the FeF3‐HT cathode's superior specific capacity and rate performance compared with other cathodes at high current densities is revealed, according to cyclic voltammogram tests under different scan rates. The cause is that FeF3‐HT has the highest proportion of the contribution capacity of the cathode surface control process. The above research opens up a new avenue for FeF3‐HT, FeF3‐RT, FeF3·0.33H2O, and FeF3·3H2O cathodes in sulfide ASSBs.

AbstractThe widespread adoption of dicamba‐resistant crops has increased the applications of newer dicamba formulations for weed control. However, there is a concern for potential off‐target injury and yield reduction to peanuts (Arachis hypogea L.) planted in close proximity to dicamba‐resistant crops. Field experiments were conducted in the summer of 2019 and 2020 to evaluate peanut response to reduced rates (1/512X, 1/128X, 1/32X, and 1/8X the label rate, 564 + 1280 g ae ha−1) of dicamba plus glyphosate (XtendiMax plus Roundup PowerMax) at 25, 50, and 75 days after planting (DAP) which corresponds to vegetative, flowering, and pod development stages, respectively. Peanut exposure to dicamba plus glyphosate at 25 DAP resulted in 1.6–2.3 times greater injury and 3.4–8.5 times greater height and canopy width reductions compared to 50 and 75 DAP exposures. Peanuts suffered greater yield reduction (18%–19%) when exposed to dicamba plus glyphosate at 25 and 75 DAP than at 50 DAP (10%). Regression analysis indicated a significant linear response for peanut injury (except at 8 weeks after treatment), canopy width reduction, and yield reduction with an increasing rate of dicamba plus glyphosate. Dicamba plus glyphosate at 1/512X rate resulted in a 3% peanut yield reduction, whereas a 41% yield reduction was observed at 1/8X rate. Correlation analysis, with Pearson's rho values ranging from 0.81 to 0.86, showed that peanut injury can be a useful predictor for estimating yield reduction. Therefore, extreme care must be taken to prevent drift occurrence or spray‐tank contamination when applying dicamba plus glyphosate on XtendFlex crops near peanut fields.

AbstractMucine sind eine Schlüsselkomponente der defensiven Schleimbarriere. Es handelt sich um ausgedehnte Fasern mit sehr hohem Molekulargewicht, deren vielfältige biologische Funktionen stark von ihren spezifischen Strukturparametern abhängen. Hier stellen wir eine Mucin‐inspirierte Nanostruktur basierend auf dendronisierten Polysulfaten auf Methacrylatbasis (MIP‐1) mit hohem Molekulargewicht (MW=450 kDa) vor. Das Thiol‐End‐funktionalisierte Mucin‐inspiriertem Polymer (MIP) wurde durch RAFT‐Polymerisation im Multi‐Gramm‐Maßstab hergestellt. Die Kryo‐Elektronentomographie‐Analyse (Kryo‐ET) von MIP‐1 bestätigte eine Mucin‐artige, wurmartige einkettige Faserstruktur (Länge=144±59 nm) in wässriger Lösung. Diese biokompatible Faser zeigte eine vielversprechende Aktivität mit einer bemerkenswert niedrigen mittleren inhibitorischen Konzentration (IC50, mit IC50=10.0 nM) gegenüber SARS‐CoV‐2 und dessen Mutantenstamm. Darüber hinaus untersuchen wir die Auswirkungen der Faserlänge auf die Hemmung gegenüber SARS‐CoV‐2, indem wir andere funktionelle Polymere (MIPs) mit unterschiedlichen Faserlängen miteinander vergleichen.

AbstractGarnet oxides such as Li6.4La3Zr1.4Ta0.6O12 (LLZTO) are promising solid electrolyte materials for all‐solid‐state lithium‐metal batteries because of high ionic conductivity, low electronic leakage, and wide electrochemical stability window. While LLZTO has been frequently discussed to be stable against lithium metal anode, it is challenging to achieve and maintain good solid‐on‐solid wetting at the metal/ceramic interface in both processing and extended electrochemical cycling. Here we address the challenge by a powder‐form magnesium nitride additive, which reacts with the lithium metal anode to produce well‐dispersed lithium nitride. The in situ formed lithium nitride promotes reactive wetting at the Li/LLZTO interface, which lowers interfacial resistance, increases critical current density (CCD), and improves cycling stability of the electrochemical cells. The additive recipe has been diversified to titanium nitride, zirconium nitride, tantalum nitride, and niobium nitride, thus supporting the general concept of reactive dispersion‐plus‐wetting. Such a design can be extended to other solid‐state devices for better functioning and extended cycle life.

AbstractThe fixing of N2 to NH3 is challenging due to the inertness of the N≡N bond. Commercially, ammonia production depends on the energy‐consuming Haber‐Bosch (H−B) process, which emits CO2 while using fossil fuels as the sources of hydrogen and energy. An alternative method for NH3 production is the electrochemical nitrogen reduction reaction (NRR) process as it is powered by renewable energy sources. Here, we report a tiara‐like nickel‐thiolate cluster, [Ni6(PET)12] (where, PET=2‐phenylethanethiol)] as an efficient electro‐catalyst for the electrochemical NRR at ambient conditions. Ammonia (NH3: 16.2±0.8 μg h−1 cm−2) was the only nitrogenous product over the potential of −2.3 V vs. Fc+/Fc with a Faradaic efficiency of 25%±1.7. Based on theoretical calculations, NRR by [Ni6(PET)12] proceeds through both the distal and alternating pathways with an onset potential of −1.84 V vs. RHE (i.e., −2.46 V vs. Fc+/Fc) which corroborates with the experimental findings.
Investigation on nitrogen oxidation characteristics and volatile–char interaction during co‐combustion of semi‐coke and bituminous coal

AbstractBlending bituminous coal (BC) in semi‐coke (SC) is a promising approach to improve the combustion behaviors of SC, while the nitrogen conversion characteristics during the co‐combustion are still unclear. This paper deals with the oxidation characteristics of volatile‐N and char‐N and their contributions to total NO during the co‐combustion of SC and BC using a volatile–char separated combustion system. By comparing the volatile–char separated combustion with the entrained flow combustion, the interaction between volatile‐N and char‐N has also been elucidated. Results indicated volatile‐N was the main contribution to total NO formation for both SC and BC at temperatures above 1000°C. The volatile‐NO and char‐NO conversion ratios presented distinct variations along with the temperature, and the temperature had different impact on the two combustion modes. The char‐NO was more sensitive to the variation of oxygen concentration, and the nitrogen conversion of SC was more susceptible to oxygen compared with that of BC. The blending of BC inhibited the volatile‐NO and char‐NO formation of SC, and the inhibition effect enhanced in pace with the blending ratio of BC. The influence of volatile–char interaction on nitrogen conversion was temperature‐dependent and fuel‐varying: for SC, it was more significant in pyrolysis stage in the temperature range of 900°C to 1400°C, and sufficient pyrolysis measures can effectively reduce the NO formation; however, the identical result occurred when the temperature exceeded 1100°C for the blend.

AbstractPVDF‐based materials have gained significant attention in the field of dielectric energy storage due to their excellent breakdown strength and energy storage density. However, the improvement has been limited by their low dielectric constant. In this article, the PVDF‐TrFE composite films with core‐shell structured (1‐x)Ba(Ti0.8Zr0.2)O3‐x(Ba0.7Ca0.3)TiO3@TiO2(BZT‐xBCT@TiO2) nanofibers were fabricated using hot pressing, electrospinning, and hydrothermal method. Doping the PVDF‐TrFE composite film with 3 wt% BZT‐0.6BCT increased its energy storage density to 14.2 J·cm−3. When the doped ceramic fibers were coated with the TiO2 core‐shell of ~75 nm, the composite film exhibits improved breakdown field strength (Eb) of 365 kV mm−1, enhanced energy storage density (Ue) of 18.71 J·cm−3, and superior energy storage efficiency (η) of 60.03%.

AbstractTimely and powerful diagnostic means can achieve better therapeutic effects, reduce disease torment, and improve survival rate. As a powerful non‐invasive spectroscopy technology, surface‐enhanced Raman scattering (SERS) have testified to be a great potential candidate for extensive early clinical disease diagnosis. In recent years, the introduction of SERS label, combined with other analysis modes or artificial intelligence, and the emergence of miniaturized devices have made SERS technology more advantageous in early diagnosis of diseases. This review focuses on the research progress of SERS dominated analytical strategies in the field of early disease diagnosis in the past five years. The main content includes the application of label‐free SERS detection; the construction of label SERS methodologies for various disease markers; SERS dominated multimode early disease diagnosis strategies; integration of SERS and artificial intelligence; portable Raman equipment and SERS imaging; and opportunities and trends for SERS diagnostic technology in the future.

AbstractOver the past decades, virus‐like particle (VLP)‐based gene therapy (GT) evolved as a promising approach to cure inherited diseases or cancer. Tremendous costs due to inefficient production processes remain one of the key challenges despite considerable efforts to improve titers. This review aims to link genome‐scale metabolic models (GSMMs) to cell lines used for VLP synthesis for the first time. We summarize recent advances and challenges of GSMMs for Chinese hamster ovary (CHO) cells and provide an overview of potential cell lines used in GT. Although GSMMs in CHO cells led to significant improvements in growth rates and recombinant protein (RP)‐production, no GSMM has been established for VLP production so far. To facilitate the generation of GSMM for these cell lines we further provide an overview of existing omics data and the highest production titers so far reported.
