AbstractDisordered superconducting nitrides with kinetic inductance have long been considered to be leading material candidates for high‐inductance quantum‐circuit applications. Despite continuing efforts toward reducing material dimensions to increase the kinetic inductance and the corresponding circuit impedance, achieving further improvements without compromising material quality has become a fundamental challenge. To this end, a method to drastically increase the kinetic inductance of superconducting materials via spinodal decomposition while maintaining a low microwave loss is proposed. Epitaxial Ti0.48Al0.52N is used as a model system and the utilization of spinodal decomposition to trigger the insulator‐to‐superconductor transition with a drastically enhanced material disorder is demonstrated. The measured kinetic inductance increases by two to three orders of magnitude compared with the best disordered superconducting nitrides reported to date. This work paves the way for substantially enhancing and deterministically controlling the inductance for advanced superconducting quantum circuits.

AbstractDeveloping high‐performance electrocatalysts for the ethanol oxidation reaction (EOR) and the oxygen reduction reaction (ORR) is essential for the commercialization of direct ethanol fuel cells, but it is still formidably challenging. In this work, a novel Pd–Sb hexagonal nanoplate for boosting both cathodic and anodic fuel cell reactions is prepared. Detailed characterizations reveal that the nanoplates have ordered rhombohedral phase of Pd8Sb3 (denoted as Pd8Sb3 HPs). The Pd8Sb3 HPs exhibit much enhanced activity toward the oxidation of various alcohols. Particularly, Pd8Sb3 HPs/C displays superior specific and mass activities of 29.3 mA cm−2 and 4.5 A mgPd−1 toward the EOR, which are 7.0 and 11.3 times higher than those of commercial Pd/C, and 9.8 and 3.8 times higher than those of commercial Pt/C, respectively, representing one of the best EOR catalysts reported to date. In situ electrochemical attenuated total reflectance surface‐enhanced infrared absorption spectroscopy (ATR‐SEIRAS) measurements reveal that Pd8Sb3 HPs/C can effectively promote the C2 pathway of the EOR. As revealed by density functional theory calculations, the high EOR activity of the Pd8Sb3 HPs can be ascribed to the reduced energy barrier of ethanol dehydrogenation. Additionally, Pd8Sb3 HPs/C also shows superior performance in the ORR. This work advances the controllable synthesis of the Pd–Sb nanostructure, giving huge impetus for the design of high‐efficiency electrocatalysts for energy conversion and beyond.

AbstractSingle‐atom catalysts have emerged as an efficient oxidant activator for eliminating organic pollutants in Fenton‐like systems. However, the complex preparation, single active site, lack of understanding of the fundamental mechanism, and harsh pH conditions currently limit their practical applications. In this work, single‐atom iron anchored nitrogen‐rich g‐C3N4 nanotubes (FeCNs) are designed and synthesized by a facile approach, and eco‐friendly peracetic acid (PAA) is selected as the oxidant for Fenton‐like reactions. The constructed heterogenous system achieves an enhanced degradation of various organic contaminants over a wide pH range of 3.0–9.0, exhibiting an ultrahigh and stable catalytic activity, outperforming equivalent quantities of pristine g‐C3N4 by 75 times. The 18O isotope‐labeling technique, probe method, and theoretical calculations demonstrate that the efficient catalytic activity relies on the high‐valency iron‐oxo species coupled with organic radicals generated by PAA. An increase in electron transport from the contaminant to the formed “metastable PAA/FeCN catalyst surface complex” is detected. A double driving mechanism for the tubular g‐C3N4 regulated by a single Fe site and PAA activation is proposed. This work opens an avenue for developing novel catalysts with the coexistence of multiple active units and providing opportunities for significantly improving catalytic efficiency.

Published: June 2022

AbstractMetal‐halide perovskites (PSKs) are emergent materials for a large range of applications, and the layered double PSK architectures vastly enrich the opportunities to design their composition, structural properties, and optoelectronic behavior. The stability, crystal phase, and electronic bandgap depend strongly on the bonds and distortions of the octahedra lattice that are at the origin of the vibrational spectrum of these materials. This work investigates the structural dynamics of flakes of exfoliated layered Ag‐Bi bromide double PSKs by angle‐dependent polarized Raman spectroscopy and density functional theory modeling. The well‐defined orientation of the inorganic octahedra lattice with respect to the light polarization allows to correlate the angle‐dependent intensity of the Raman signal to the directionality and symmetry of the phonon modes. Low‐frequency vibrations are revealed for which a detailed microscopic and group theory assignment of the Raman modes is provided. The temperature‐dependent measurements across the phase transitions show marked changes in the phonon frequencies, reveal soft modes, and help to distinguish first from second‐order transitions as well as to determine their transition temperature. This provides highly valuable insights to improve the properties of this class of Pb‐free PSKs for applications in energy harvesting and optoelectronics.

AbstractEarly detection and diagnosis are vitally important in reducing the mortality rate of fatal diseases but require highly sensitive detection of biomarkers. Presently, detection methods with the highest sensitivity require in vitro processing, while in vivo compatible fluorescence detections require a much higher concentration of biomarkers or limit of detection (LOD). In this paper, a fundamentally new strategy for ultrasensitive detection based on color‐switchable lasing with a cavity‐enhanced reduction of LOD is demonstrated, down to 1.4 × 10−16 mg ml−1 for a quantitative detection, lower than both the fluorescence method and plasmonic enhanced method. For a qualitative or a yes/no type of detection, the LOD is as low as 10–17 mg ml−1. The approach in this work is based on a dye‐embedded, in vivo compatible, polystyrene‐sphere cavity, penetrable by biomarkers. A polystyrene sphere serves the dual roles of a laser cavity and an in vivo bio‐reactor, in which dye molecules react with a biomarker, reporting biomarker information through lasing signals. The cavity‐enhanced emission and lasing with only a single biomarker molecule per cavity allow improved visual distinguishability via color changes. Furthermore, when combined with a narrow‐band filter, the color‐switchable lasers act as an “on‐off” logic signal and can be integrated into multiplexing detection assay biochips.

AbstractDynamic windows allow user control over light and heat flow to save energy and maximize comfort. Reversible metal electrodeposition (RME) dynamic windows can uniquely tint to a color‐neutral privacy state (0.1% visible light transmission). The design parameters of transparent metal mesh counter electrodes for high‐contrast RME dynamic windows: high transparency, charge capacity and surface area with low haze, sheet resistance and cost are discussed, concluding that woven metal meshes meet these design parameters. Electroplated current is measured on an indium tin oxide electrode and two meshes with different wire spacings, showing the meshes’ cylindrical geometry enable them to draw more current per square area. The mesh material composition is analyzed to ensure cycling durability in a CuBi electrolyte by developing a transparent mesh with an inert core (stainless steel, SS), a thin Au coating, and a high charge‐capacity (1.5 C cm−2) CuBi outer coating. The study demonstrates that the films maintain a consistent Cu:Bi ratio and optical properties after 250 privacy cycles or 1500 cycles to 10% transmission, showing that the Cu and Bi coating is effective in keeping the films from becoming Cu rich with cycling. Finally, a 100 cm2 device with excellent uniformity and color neutrality is demonstrated.

AbstractOrganic solar cells (OSCs) are promising wearable/stretchable power sources, but the development of high‐performance intrinsically stretchable OSCs (IS‐OSCs) has rarely been reported. Herein, IS‐OSCs exhibiting high power conversion efficiencies (PCEs) (>12%) and excellent stretchability are developed by constructing efficient and mechanically robust active layers via the addition of a high‐molecular weight polymer acceptor (PA) to polymer donor:small‐molecule acceptor blends. PA addition significantly enhances the stretchability and PCEs of the blends as the long PA chains function as molecular bridges between different domains, effectively dissipating mechanical stresses and improving charge transport. The IS‐OSCs with 20 wt% PA content exhibit a high PCE of 11.7% and excellent stretchability, retaining 84% of the initial PCE after 100 cycles of repetitive stretching/releasing at a 15% strain. To the best of the authors’ knowledge, the device represents the best IS‐OSC performance reported to date in terms of PCE and stretchability, demonstrating the great potential of IS‐OSCs as an efficient and wearable power generator.

Published: June 2022

AbstractRecent wide spreads between boxed beef cutout values and fed cattle prices have reignited beef cattle producers' long‐held concerns about price discovery. The recent concerns have led to policy proposals meant to increase negotiated trade volumes in the cash market. We determine how volume, day of the week, sex, grade, weight range, and other factors impact price ranges in the negotiated cash market. We find many factors, in addition to sales volume, can impact price ranges. The analysis provides insight into current policy proposals, and we discuss the need for more detailed data for precise answers to current policy questions.
The order flow cost of index rolling in commodity futures markets
Authors: Irwin Scott H. , Sanders Dwight R. , Yan Lei 
Published: June 2022

AbstractCommodity index rolling is treated as a natural experiment and an event study of order flow costs in a wide array of futures markets is conducted. The spread between nearby and deferred futures prices decreases significantly in the early and growth phases of financialization (1991–2011), with the spreads reversing back after rolling is completed. Spread impacts disappear in the post‐financialization period (2012–2019). We argue that a dramatic increase in the supply of liquidity brought on by the transition to electronic trading in commodity futures markets is primarily responsible for the decline of roll order flow costs.

AbstractBackgroundGastric emphysema and emphysematous gastritis (EG) are rare diseases involving air being introduced into the stomach wall. Emphysematous gastritis is an infectious disease with a high fatality rate.Case presentationAn 83‐year‐old woman had recovered from septic shock, however, an antibiotic‐refractory inflammatory response remained. She was diagnosed with pseudogout and administered a non‐steroidal anti‐inflammatory drug. However, abdominal pain, prominent abdominal distension, and strawberry milk‐like gastric juice were recognized. Computed tomography showed ileus due to fecal impaction and GE. The results of culture of the gastric juice were positive (Pseudomonas aeruginosa and Enterococcus faecalis). Disimpaction, fasting management, and antibacterial treatments resulted in the recovery of her symptoms.ConclusionThis is the first case in which ileus associated with fecal impaction caused EG. The present case highlights the importance of promoting regular bowel movements.

AbstractAqueous zinc–air batteries possess inherent safety and are especially commendable facing high‐temperature working conditions. However, their working feasibility at high temperatures has seldom been investigated. Herein, the working feasibility of high‐temperature zinc–air batteries is systemically investigated. The effects of temperature on air cathode, zinc anode, and aqueous electrolyte are decoupled to identify the favorable and unfavorable factors. Specifically, parasitic hydrogen evolution reaction strengthens at high temperatures and leads to declined anode Faraday efficiency, which is identified as the main bottleneck. Moreover, zinc–air batteries demonstrate cycling feasibility at 80 °C. This work reveals the potential of zinc–air batteries to satisfy energy storage at high temperatures and guides further development of advanced batteries towards harsh working conditions.

AbstractProtonic ceramic fuel cells (PCFCs) are energy conversion devices based on proton conducting oxide electrolytes, which efficiently convert the chemical energy of fuel into electrical energy during operation. Since the conduction of protons has a lower activation energy than the conduction of oxygen ions, PCFCs can work at medium to low temperatures. In order to obtain better output performance at medium to low temperatures, the cathode of PCFCs needs to have better activity, and the triple (H+/O2−/e−) conducting oxide is a very good choice. In this study, the triple conducting BaCe0.16Y0.04Fe0.8O3‐δ (BCYF) cathode material was synthesized by the traditional solid‐state reaction method, and the structure and morphology of the cathode material during the synthesis process were investigated. The results show that the powder synthesized by the solid‐state reaction method has a particle size comparable with that of the wet chemical method, and the as‐fabricated electrode exhibits a polarization resistance of 0.91 Ω cm2 at 700°C on the Ba Zr0.1Ce0.7Y0.1Yb0.1O3‐δ (BZCYYb) electrolyte of 0.91 Ω cm2 at 700°C. A fuel cell, using Ni‐BZCYYb anode, BZCYYb electrolyte, and BCYF cathode, achieves a maximum power density of 213 mW cm−2 at 600°C.
Study of hydrogen sulfide effect on acrylonitrile butadiene rubber/hydrogenated acrylonitrile butadiene rubber for sealing application in oil and gas industry

Published: June 2022

AbstractAcrylonitrile Butadiene Rubber (NBR) and Hydrogenated Acrylonitrile Butadiene Rubber (HNBR) have been widely used in many sealing applications for downhole operation. To build practical operation limits for NBR and HNBR packer elements, it is required to fill the gap between laboratory‐scale tests and field operation experience on how packer elements behave in such conditions. This study encompassed the experimental work on NBR and HNBR packer elements exposed to various sour conditions comparable to field operation. The elastomer specimens, such as NBR, showed less resistant to H2S in the controlled laboratory tests (e.g., at 121°C and 52.5 MPa with 5% of H2S) compared with an uncontrolled environment inside oil and gas well (e.g., at 134°C and 47 MPa with 3.5% of H2S). The behavior could be explained by different exposure conditions like exposure geometry, stress, temperature, pressure, and H2S concentrations. This is potentially the first‐ever comprehensive study in the oil and gas industry, which shows that the operation limit of NBR and HNBR packer elements can be extended to a higher H2S concentration.

AbstractMost graph neural networks (GNNs) in deep‐learning chemistry collect and update atom and molecule features from the fed atom (and, in some cases, bond) features, basically based on the two‐dimensional (2D) graph representation of 3D molecules. However, the 2D‐based models do not faithfully represent 3D molecules and their physicochemical properties, exemplified by the overlooked field effect that is a “through‐space” effect, not a “through‐bond” effect. We propose a GNN model, denoted as MolNet, which accommodates the 3D non‐bond information in a molecule, via a noncovalent adjacency matrix, and also bond‐strength information from a weighted bond matrix. Comparative studies show that MolNet outperforms various baseline GNN models and gives a state‐of‐the‐art performance in the classification task of BACE dataset and regression task of ESOL dataset. This work suggests a future direction for the construction of deep‐learning models that are chemically intuitive and compatible with the existing chemistry concepts and tools.

AbstractIntroductionSeasonal inactivated influenza vaccine (IIV) is routinely recommended during pregnancy to protect both mothers and infants from complications following influenza infection. While previous studies have evaluated the risk of major structural birth defects in infants associated with prenatal administration of monovalent pandemic IIV, fewer studies have evaluated the risk associated with prenatal seasonal IIV.MethodsWe conducted a population‐based cohort study of 125,866 singleton births between 2012 and 2016 in Western Australia. Birth registrations were linked to the state's registers for congenital anomalies and a state prenatal vaccination database. We estimated prevalence ratios (PR) of any major structural birth defect and defects by organ system. Vaccinated pregnancies were defined as those with a record of IIV in the first trimester. Inverse probability treatment weighting factored for baseline probability for vaccination. A Bonferroni correction was applied to account for multiple comparisons.ResultsAbout 3.9% of births had a major structural birth defect. Seasonal IIV exposure during the first trimester was not associated with diagnosis of any major structural birth defect diagnosed within 1 month of birth (PR 0.98, 95% CI: 0.77, 1.28) or within 6 years of life (PR 1.02, 95% CI: 0.78, 1.35). We identified no increased risk in specific birth defects associated with seasonal IIV.ConclusionBased on registry data for up to 6 years of follow‐up, results suggest there is no association between maternal influenza vaccination and risk of major structural birth defects. These results support the safety of seasonal IIV administration during pregnancy.

AbstractBackgroundSQSTM1/p62 is a selective autophagy receptor that regulates multiple signaling pathways participating in the initiation and progression of tumors. Metastasis is still the main cause for intrahepatic cholangiocarcinoma (ICC)‐associated mortality. Hence, this study aimed to explore the mechanism of p62 promoting the progression of ICC.MethodsWestern blotting and immunohistochemical analyses were conducted to detect the expression level of protein p62 in ICC tissues and its correlation with prognosis. Subsequently, the loss‐of‐function experiments in vitro and in vivo were performed to define the role of p62 in ICC cell proliferation, invasion, and metastasis. Then, the effect of p62 knockdown on mitochondrial function and mitophagy was evaluated by measuring the oxygen consumption rate, and using immunofluorescence and western blotting analyses.ResultsThe expression of p62 was significantly upregulated in ICC specimens compared with normal tissues. We further illustrated that p62 expression positively correlated with lymph node metastasis and poor prognosis. The loss‐of‐function assays revealed that p62 not only promoted ICC cell proliferation, migration, and invasive capacities in vitro, but also induced lung metastasis in the xenograft mouse model. Mechanistically, high expression of p62‐induced epithelial–mesenchymal transition (EMT) with the upregulation of Snail, vimentin, N‐cadherin, and downregulation of E‐cadherin. Moreover, the autophagy‐dependent function of p62 might play a vital role in maintaining the mitochondrial function of ICC by mitophagy which might further promote EMT.ConclusionThese data provided new evidence for the mechanism by which abundant p62 expression promoted ICC progression, suggesting a promising therapeutic target for antimetastatic strategies in patients with ICC.
