Published: September 2022

AbstractTwo‐dimensional MoS2 field‐effect transistors (FETs) have great potential for next‐generation electronics due to their excellent electronic properties with an atomic thin channel. However, multiple challenges exist for the monolayer MoS2 channel, including interface scattering and ohmic contact. In this work, well‐controlled trilayer MoS2 with high mobility and large single crystals is successfully grown on soda‐lime glass substrates using chemical vapor deposition, with a lateral size of up to 148 µm, which is the largest reported size to date. A record high on/off ratio of ≈1012 and a high carrier mobility of 62 cm2 V−1 s−1 of trilayer MoS2 FETs are demonstrated, showing notable advantages compared with the monolayer counterpart. The long‐standing issue of monolayer MoS2 performance degradation from physical vapor deposited metal contact can be mitigated by the trilayer MoS2 channel, achieving the lowest contact resistance of 350 Ω µm using the common method of e‐beam evaporated Ni. Moreover, 40‐nm channel‐length trilayer MoS2 FETs using ultrathin HfLaO dielectrics exhibit a high current of 589 µA µm−1 at a supply voltage of 1 V at room temperature, which increases to 1162 µA µm−1 at 4.3 K, the highest among those using commonly evaporated metal. Record high electron saturation velocity of 4.2 × 106 cm s−1 can be achieved at room temperature.

AbstractPotassium–sulfur (K–S) batteries are emerging as low‐cost and high‐capacity energy‐storage technology. However, conventional K–S batteries suffer from two critical issues that have not yet been successfully resolved: the dissolution of potassium polysulfides (KPS) into the liquid electrolyte and the formation of K dendrites on the K metal anode, which lead to inadequate cycling efficiencies with a low reversible capacity. Herein, a high‐capacity and long cycle‐life K–S battery consisting of a highly concentrated electrolyte (HCE) (4.34 mol kg−1 potassium bis(fluorosulfonyl)imide in a 1,2‐Dimethoxyethane) and a sulfurized polyacrylonitrile (SPAN) cathode is presented The application of a HCE efficiently suppresses the dendritic growth of K, as evidenced by operando optical imaging and phase field modeling, owing to the reduced K‐ion depletion on the electrode surface and a uniform Faradaic current density over the K metal anode surface. Additionally, because S is covalently bonded to the C backbone of PAN in the SPAN structure, the SPAN cathode inhibits the dissolution of KPS. These features generate synergy that the proposed K–S battery can provide a practical areal capacity of 2.5 mAh cm−2 and unprecedented lifetimes with high Coulombic efficiencies over 700 cycles.

Published: September 2022

AbstractThe poor Zn reversibility has been criticized for limiting applications of aqueous Zn‐ion batteries (ZIBs); however, its behavior in aqueous media is not fully uncovered yet. Here, this knowledge gap is addressed, indicating that Zn electrodes face a O2‐involving corrosion, besides H2evolution and dendrite growth. Differing from aqueous Li/Na batteries, removing O2cannot enhance ZIB performance because of the aggravated competing H2evolution. To address Zn issues, a one‐off electrolyte strategy is reported by introducing the triple‐function C3H7Na2O6P, which can take effects during the shelf time of battery. It regulates H+concentration and reduces free‐water activity, inhibiting H2evolution. A self‐healing solid/electrolyte interphase (SEI) can be triggered before battery operation, which suppresses O2adsorption corrosion and dendritic deposition. Consequently, a high Zn reversibility of 99.6% is achieved under a high discharge depth of 85%. The pouch full‐cell with a lean electrolyte displays a record lifespan with capacity retention of 95.5% after 500 cycles. This study not only looks deeply into Zn behavior in aqueous media but also underscores rules for the design of active metal anodes, including Zn and Li metals, during shelf time toward real applications.
Porous‐Structure‐Promoted Tribo‐Induced High‐Performance Self‐Powered Tactile Sensor toward Remote Human‐Machine Interaction
Authors: Su Li , Xiong Quan , Wang Haoyu , Zi Yunlong 
Published: September 2022

AbstractSelf‐powered tactile sensor with versatile functions plays a significant role in the development of an intelligent human‐machine interaction (HMI) system. Herein, a hybrid self‐powered porous‐structured tactile sensor (SPTS) is proposed by monolithically integrating a porous triboelectrification‐induced electroluminescence (TIEL) component and a single‐electrode triboelectric nanogenerator with the high charge generation in the bulk volume. At a low pressure of 10 kPa, TIEL intensity can be significantly improved by three times, which is superior to that in previous reports, with enhanced triboelectricity. Based on the enhancement brought by the porous structure and optimized parameters, the SPTS achieves significant sensing performance in both optical and electrical modes. To demonstrate the potential of practical applications, a programmable optical and electrical dual‐mode HMI system is established based on SPTS to remotely control an intelligent vehicle and operate a computer game through identifying finger touch trajectories. This work not only contributes a new economical‐effective methodology toward a high‐performance tribo‐induced self‐powered tactile sensor but also facilitates the remote control of HMI with dual‐mode functionality, which has broad potential applications in the fields of intelligent robots, augmented reality, flexible wearable electronics, and smart home.
A tale of two fields: Management legacy, soil health, and productivity

Published: September 2022

AbstractAdjacent fields with contrasting histories present an opportunity to evaluate the legacy of management on soil health (SH) and grain productivity. In 2011, two fields transitioned to no‐till grain production. During the previous 25 yr, one was pasture (pasture‐to‐grain; PTG), whereas the other was annually tilled for grain cropping (long‐term grain; LTG). The study objectives were to contrast these two fields relative to SH and productivity. Yield data was collected from 2011 to 2021 and SH sampled in 2021. The PTG out‐yielded LTG each year, with an average 46% yield increase. 2021 SH metrics demonstrated similar trends, with PTG 62% higher than LTG. Contrasting across fields (2020–2021), SH metrics were related to yield (r2 = .46–.78), but these relationships weakened when assessed within each field. These findings affirm SH indicators are sensitive to the legacy of management and are meaningful indicators of productivity across sites but less informative for within‐field variability.

AbstractTraditional Hawaiian fishponds, called loko iʻa, are a low‐impact and culturally important aquaculture system that historically produced significant fish yields. To better understand the structure of the contemporary food web of the restored Heʻeia fishpond, a mark‐recapture experiment was conducted to estimate the population abundance of the three dominant predatory fishes, and gut content, genetic barcoding, and stable isotope analyses were used to assess their diets. Great barracuda Sphyraena barracuda had the largest estimated population at 190 individuals, followed by 89 giant trevally Caranx ignobilis and 19 bluefin trevally Caranx melampygus. The three species were caught throughout the pond, with C. ignobilis concentrated in the deeper northwest area near a mangrove island. Diets of the three species consisted mainly of nearshore, estuarine fishes, and crustaceans. Prey taxonomic resolution was greatly improved with the use of genetic barcoding since most fish were too degraded to be visually identified. Trophic level calculations and isotopic niche breadth comparisons indicated that C. ignobilis and S. barracuda occupied similar ecological niches in the fishpond, and stable isotope mixing models revealed that their long‐term diets were mostly comprised glass shrimp (Palaemon sp.), mangrove swimming crab (Thalamita crenata), and an invasive Australian mullet (Osteomugil engeli). The native mullet (Mugil cephalus), a primary food fish species from the fishpond, was not identified in the diets of the predatory fishes in this study nor in a previous diet study decades ago prior to the introduction of Australian mullet. The inclusion of the invasive Australian mullet in the contemporary diets of the predatory fishes demonstrates a shift towards the newly available prey which may benefit the native mullet populations. These findings improve the understanding of food web dynamics in contemporary Hawaiian fishponds and provide an example of native predatory fishes consuming an invasive species as part of their diets.

AbstractEnhancing energy cane biomass production can increase feedstock supply for lignocellulosic‐based ethanol production. This study was conducted at the Louisiana State University Agricultural Center (LSU AgCenter) Sugar Research Station in St. Gabriel, LA, from 2013 to 2015 to evaluate yield, fiber composition, and nutrient removal rate of energy cane harvested at different dates. The treatments included two energy cane cultivars (‘Ho 02‐113’ and ‘Ho 72‐114’) and four N rates (0, 56, 112, and 224 kg N ha–1), arranged in split plot in a randomized complete block design with four replications. Fifteen plants were collected once a month beginning 2 mo prior to the harvest date and then separated into leaves and stalks and analyzed for fiber and nutrient composition. Harvest date, cultivar, and N rate significantly affected energy cane yield (stalk and leaves), quality components, lignocellulosic composition, and nutrient removal rate (p < .05). On average, harvesting energy cane 1 and 2 mo earlier than the scheduled harvest date reduced stalk yield by 4% and 20% and leaf yield by 3% and 15%. Minimal changes on stalk fiber content and lignocellulosic composition in response to the treatments were documented but no specific and consistent trend was established. With leaf included, energy cane biomass production was increased by 32%; however, this can result in significant removal of plant essential nutrients, particularly N (105 kg ha–1), P (16 kg ha–1), and K (116 kg ha–1). The long‐term impact of complete removal of energy cane biomass from the field could result in decline in soil fertility and productivity.
Short‐term corn yield response associated with nitrogen dynamics from fall‐seeded cover crops under no‐till dryland conditions

Published: September 2022

AbstractThe availability of in‐season N to corn (Zea maysL.) following fall‐seeded cover crops depends on seasonal patterns of nitrogen (N) transformations that are site‐ and year‐dependent and resist prediction. Our objectives were to evaluate N dynamics following different cover crops (legume, nonlegume, none) and their relationship with subsequent corn yields within an established no‐till winter wheat (Triticum aestivumL.)–cover crop/corn–soybean (Glycine max) rotation over two site‐years in the U.S. Northern Plains. Spring cover crop biomass and N uptake, in‐situ soil N mineralization following cover crop termination, and corn grain yield and N uptake were measured. Legume cover crops were associated with higher corn yields, whereas rye (Secale cereale) did not significantly decrease corn yields despite N immobilization by a large rye cover crop in one year. Legume cover crops produced the highest rates of N mineralization during periods of high N demand by corn (V6–R3) and the highest seasonal amounts of mineralized N compared with rye or no cover crops. In‐situ N mineralization measurements better predicted yields across all treatments compared with approaches using cover crop biomass and N content. In situ N mineralization rates during corn growth stages V6–R3 provided a superior prediction (r = .83) of corn yields compared with all seasonal estimates of N provided by cover crops. Lower apparent N use efficiency calculated with contributions of in‐season N mineralization indicated that less fertilizer N can be applied in the growing season following legume cover crops.

Published: September 2022

AbstractIn this article, through the optimized arrangement of the magnetized plasma, dielectric, and nonlinear Kerr dielectric, a tunable reflection phase retarder with a certain bandwidth is investigated. When the electric field of the incident electromagnetic wave is parallel to the xoy plane and has an angle of 45° with the x‐axis, the electric field can be further decomposed into Ex and Ey along the x‐ and y‐axes, indicating TM and TE waves, respectively. The results show that under reasonable parameters, the 180° or −180° phase delay of the reflected wave of the proposed structure is obtained and adjusted. In particular, the nonlinear bistable response at this performance is also demonstrated. Furthermore, to verify the superiority of the obtained bandwidth of the phase retarder, the influences of the incident angle, the plasma frequency, the external magnetic field, and the nonlinear light intensity on the bandwidth of the phase retarder have been studied. It is observed that the total phase retarder bandwidth can reach 2.6 GHz by appropriately optimizing those parameters. Additionally, this work provides constructive suggestions for tunable broadband phase blockers and half‐wave plates, and it still holds some potential significance in the radome.

AbstractTargeted α therapy (TAT) is a promising tool in the therapy of cancer. The radionuclide 213BiIII shows favourable physical properties for this application, but the fast and stable chelation of this metal ion remains challenging. Herein, we demonstrate that the mesocyclic chelator AAZTA quickly coordinates BiIII at room temperature, leading to a robust complex. A comprehensive study of the structural, thermodynamic and kinetic properties of [Bi(AAZTA)]− is reported, along with bifunctional [Bi(AAZTA‐C4‐COO−)]2− and the targeted agent [Bi(AAZTA‐C4‐TATE)]−, which incorporates the SSR agonist Tyr3‐octreotate. An unexpected increase in the stability and kinetic inertness of the metal chelate was observed for the bifunctional derivative and was maintained for the peptide conjugate. A cyclotron‐produced 205/206Bi mixture was used as a model of 213Bi in labelling, stability, and biodistribution experiments, allowing the efficiency of [213Bi(AAZTA‐C4‐TATE)]− to be estimated. High accumulation in AR42J tumours and reduced kidney uptake were observed with respect to the macrocyclic chelate [213Bi(DOTA‐TATE)]−.
Direct Acquisition of the Gap Height of Biological Tissue‐Electronic Chemical Sensor Interfaces
Authors: Zhang Xin‐Wei , Hatamie Amir , Ewing Andrew G. 
Published: September 2022

AbstractInterfacing biological tissues with electronic sensors offers the exciting opportunity to accurately investigate multiple biological processes. Accurate signal collection and application are the foundation of these measurements, but a long‐term issue is the signal distortion resulting from the interface gap. The height of the gap is the key characteristic needed to evaluate or model the distortion, but it is difficult to measure. By integrating a pair of nanopores at the electronic sensor plane and measuring the ion conductance between them, we developed a versatile and straightforward strategy to realize the direct cooperative evaluation of the gap height during exocytotic release from adrenal gland tissues. The signaling distortion of this gap has been theoretically evaluated and shows almost no influence on the amperometric recording of exocytosis in a classic “semi‐artificial synapse” configuration. This strategy should benefit research concerning various bio/chemical/machine interfaces.

Published: September 2022

AbstractTransition metal‐catalyzed carbonylative cross‐coupling reactions are some of the most widely used methods in organic synthesis. However, despite the obvious advantages of iron as an abundant and low toxicity transition metal catalyst, its practical application in carbonylation reaction remains largely unexplored. Here we report our recent study on Fe‐catalyzed alkoxycarbonylation of alkyl halides. Mechanistic studies indicate that the reaction is catalyzed by an in situ generated Fe2−complex. This low‐valent iron species activates alkyl bromides via a distinctive two‐electron transfer (TET) process, whereas it proceeds via a single electron transfer (SET) process for alkyl iodides which is consistent with literature.

Published: September 2022

AbstractDeveloping efficient piezocatalytic systems for two‐electron water splitting (TEWS) with producing H2 and H2O2 shows great promise to meet the industrial demand. Herein, Ag single atoms (SAs) and clusters are co‐anchored on carbon nitride (AgSA+C−CN) to serve as the multifunctional sites for efficient TEWS. The Ag SAs enhance the in‐plane piezoelectric polarization of CN that is intimately modulated by the atomic coordination induced charge redistribution, and Ag clusters afford strong interfacial electric field to remarkably promote the out‐of‐plane migration of piezoelectrons from CN. Moreover, AgSA+C−CN yields a larger piezoresistive effect that elevates carrier mobility under strain. Consequently, a superior H2 and H2O2 evolution rate of 7.90 mmol g−1 h−1 and 5.84 mmol g−1 h−1 is delivered by AgSA+C−CN, respectively, far exceeding that of the previously reported piezocatalysts. This work not only presents the SAs decoration as an available polarization enhancement strategy, but also sheds light on the superiority of multi‐sites engineering in piezocatalysis.

Published: September 2022

AbstractA single‐phase perovskite LaAlO3:Dy3+ phosphor was synthesized using a gel‐combustion method at 600°C utilization with hexamethylenetetramine as a fuel. Further calcination of the samples was carried out (800 and 1000°C) to investigate the resultant effect on the crystalline and luminescence behaviour. The crystal structure had a cubic unit cell (space group Pm3̅m) and was examined using the Rietveld refinement and X‐ray diffraction data. Additionally, Debye–Scherrer and Williamson–Hall equations were applied to determine other structural features. The particle size and morphology of phosphors were evaluated using transmission electron microscopy. Diffraction measurements were supported by the various metal–oxygen vibration modes studied with the help of Fourier transform infrared spectroscopy. Energy‐dispersive X‐ray analysis verified the chemical composition of synthesized sample. Luminescence spectra of the LaAlO3:Dy3+ phosphors exhibited intense bands for 4F9/2→6H15/2 (482 nm, bluish region) and 4F9/2→6H13/2 (574 nm, yellowish region) transitions. Commission Internationale de L'Eclairage and correlated colour temperature data confirmed the cool‐white emission of the samples under ultraviolet light excitation. The interesting and advantageous luminescence characteristics of LaAlO3:Dy3+ phosphors make them potential materials for white light‐emitting diodes.

Published: September 2022

AbstractTwo simple, sensitive, and low‐cost fluorescence spectroscopy methods for neomycin (NEO) detection were developed. Both methods were based on the interaction between NEO and Congo red (CR) in acidic buffer medium to form an ion‐association complex. The quenching effect of the formed ion‐association complex on the fluorescence of CR at 421 nm is a basic principle of fluorescence analysis, whilst the resonance Rayleigh scattering (RRS) method was used to enhance the resonance Rayleigh scattering spectrum at 384 nm by adding NEO. Experimental conditions such as pH, temperature, reaction time, CR concentration, and the ionic strength of the two methods were investigated and optimized. In addition, the effect of common coexisting substances on the method was tested and the results showed good selectivity. The composition of ion‐association complexes, the reaction mechanism, and reasons for the enhanced intensity of RRS are discussed. Under optimum conditions, the responses of the fluorescence spectrophotometry and RRS methods showed good linearity with NEO concentrations in the range 0.2–3.0 μg ml−1 and 0.1–3.0 μg ml−1, respectively. The detection limits of fluorescence spectrophotometry and RRS spectroscopy techniques were 0.02 μg ml−1 and 0.01 μg ml−1, respectively. Finally, the two methods were applied to the analysis of wastewater and the results were satisfactory.
