AbstractThe development of 1D fiber‐shaped supercapacitors (SCs) with high volumetric energy density is of great significance for miniature wearable electronics, where limiting the device's volume is critical. In this study, a partially unzipped carbon nanotube/reduction graphene oxide (PUCNT/RGO) hybrid fiber with less “dead volume” and a well‐ordered porous structure is fabricated via wet spinning of a mixed partially unzipped oxidized carbon nanotube (PUOCNT)/GO solution and chemical reduction. The spinning solution is of low viscosity and high concentration, which can ensure smooth spinning while reducing the mass transfer during phase separation, thus lessen the “dead volume” derived from isolated pores. Moreover, PUOCNT with 1D and 2D hybrid nanoarchitecture, large specific surface area, and good water solubility can be a more effective spacer to inhibit the restacking of graphene oxide sheets while reducing the spacer itself and the large spacious voids formed “dead volume”. The all‐solid‐state SC assembled from the PUCNT/RGO hybrid fiber exhibits an excellent volumetric energy density of 8.63 mWh cm−3, exceeding the values of previously reported carbon‐based fibers. The findings may open a door for finely controlling the density and pore structure of graphene‐based fiber for applications in high volumetric energy storage via a scalable and efficient process.

AbstractRechargeable zinc–air batteries constitute promising next‐generation energy storage devices due to their intrinsic safety, low cost, and feasibility to realize high cycling current density and long cycling lifespan. Nevertheless, their cathodic reactions involving oxygen reduction and oxygen evolution are highly sluggish in kinetics, requiring high‐performance noble‐metal‐free bifunctional electrocatalysts that exceed the current noble‐metal‐based benchmarks. Herein, a noble‐metal‐free bifunctional electrocatalyst is fabricated, which demonstrates ultrahigh bifunctional activity and renders excellent performance in rechargeable zinc–air batteries. Concretely, atomic Co–N–C and NiFe layered double hydroxides (LDHs) are respectively selected as oxygen reduction and evolution active sites and are further rationally integrated to afford the resultant CoNC@LDH composite electrocatalyst. The CoNC@LDH electrocatalyst exhibits remarkable bifunctional activity delivering an indicator ΔE of 0.63 V, far exceeding the noble‐metal‐based Pt/C+Ir/C benchmark (ΔE = 0.77 V) and most reported electrocatalysts. Correspondingly, ultralong lifespan (over 3600 cycles at 10 mA cm−2) and excellent rate performances (cycling current density at 100 mA cm−2) are achieved in rechargeable zinc–air batteries. This work highlights the current advances of bifunctional oxygen electrocatalysis and endows high‐rate and long‐cycling rechargeable zinc–air batteries for efficient sustainable energy storage.

AbstractEnergycane (Saccharum hybrid) could be a viable bioenergy crop for the Southeast United States. Five energycane cultivars were planted in 2008 at a northern (Watkinsville, GA) and a southern (Tifton, GA) site, and were grown for 7 yr to compare biomass yields. Plots were arranged in a four replicate randomized complete block design at each site. Energycane was grown under rainfed conditions with 90–112 kg ha–1 N applied annually. Plant height was recorded at least monthly, and stalks were sampled to determine juice volume and Brix (estimate of sugar concentration) at harvest. Whole plots were mechanically harvested each year after killing freeze and weighed to determine biomass yields. Biomass yield and mature plant height were strongly correlated at both Tifton (r = .746) and Watkinsville (r = .727). Biomass yields peaked in Year 4 at Tifton (39.8 Mg ha–1) and Year 5 at Watkinsville (30.5 Mg ha–1), but local weather conditions had a greater influence on yields than stand age. Day‐long freezes during the winter and late spring freezes after shoot emergence resulted in reduced growth rate and yields in subsequent growing seasons. These cold weather events were more common at Watkinsville than Tifton, resulting in yields being more variable at the northern location. The greatest yielding cultivars were Ho 06‐9001 (27.0 Mg ha–1) and Ho 06‐9002 (25.1 Mg ha–1). Stability analysis revealed that these two cultivars responded positively to favorable environments in terms of biomass yield and plant height.

AbstractBacterial infections are a serious threat to human health due to the development of resistance against the presently used antibiotics. The problem of growing and widespread antibiotic resistance is only getting worse with the shortage of new classes of antibiotics, creating a substantial unmet medical need in the treatment of serious bacterial infections. Therefore, in the present work, we report 18 novel hybrid thiazolidine–1,2,4‐triazole derivatives as DNA gyrase inhibitors. The derivatives were synthesized by multistep organic synthesis and characterized by spectroscopic methods (1H and13C nuclear magnetic resonance and mass spectroscopy). The derivatives were tested for DNA gyrase inhibition, and the result emphasized that the synthesized derivatives have a tendency to inhibit the function of DNA gyrase. Furthermore, the compounds were also tested for antibacterial activity against three Gram‐positive (Bacillus subtilis[NCIM 2063],Bacillus cereus[NCIM 2156],Staphylococcus aureus[NCIM 2079]) and two Gram‐negative (Escherichia coli[NCIM 2065],Proteus vulgaris[NCIM 2027]) bacteria. The derivatives showed a significant‐to‐moderate antibacterial activity with noticeable antibiofilm efficacy. Quantitative structure–activity relationship (QSAR), ADME (absorption, distribution, metabolism, elimination) calculation, molecular docking, radial distribution function, and 2D fingerprinting were also performed to elucidate fundamental structural fragments essential for their bioactivity. These studies suggest that the derivatives10band10nhave lead antibacterial properties with significant DNA gyrase inhibitory efficacy, and they can serve as a starting scaffold for the further development of new broad‐spectrum antibacterial agents.

Published: March 2021

AbstractThis study seeks to understand the specific factors on social media that help drive the intention to purchase fashion‐related products, focusing on the central role of trust. The unique contribution of this research lies in its exploration of the interplay between perceived usefulness of the fashion brand's social media and peer communication on the fashion brand's social media in driving trust in the fashion brand's social media and, ultimately, purchase intention. Theoretically, we combine the technology acceptance model and consumer socialisation theory to explore the mediating role of trust in a rapidly expanding and growing industry sector. In surveying 150 Europeans to test our hypotheses around the aforementioned concepts, findings show that the perceived usefulness of a brand's social media is impacted by a set of atmospheric cues, and it influences the level of trust in both the fashion brand and its social media channels. Peer communication also influences perceived usefulness and level of trust in both the fashion brand and its social media channels. Trust in the brand but not its social media channels impacts purchase intention. The role of privacy concerns is limited in our model. We draw implications for theory around combining consumer socialisation theory and the technology acceptance model and for managers around parallel strategies to build different sets of trust on social media.

AbstractThe hole oxidation of Bi2WO6 occurs on Bi or O sites, thus, enhancing the proportion of {001} facets of Bi2WO6 in photocatalysis has received increased attention because of its promotion of the hole oxidation. In this work, we successfully fabricated {001} facets highly exposed Bi2WO6 nanoplate arrays (Bi2WO6 NAs) photoelectrode growing on indium tin oxides (ITO) substrate in situ. After electrochemical deposition of NiFe‐layered double hydroxide (LDH) on Bi2WO6 NAs, NiFe−LDH/Bi2WO6 NAs photoelectrode was also obtained for the first time. Bi2WO6 with a large proportion of {001} facets facilitate the photocatalytic oxidation reactions, and NiFe−LDH can induce photogenerated holes transfer from Bi2WO6 to NiFe−LDH simultaneously. The NiFe−LDH/Bi2WO6 NAs photoelectrode presents superior photoelectrochemical properties than pure Bi2WO6 NAs photoelectrode, which was characterized by transient photocurrent and electrochemical impedance spectroscopy (EIS) systematically. Taking bisphenol A (BPA) as a model pollutant, the NiFe−LDH/Bi2WO6 NAs photoelectrode exhibits much higher photocatalytic (PC) and photoelectrocatalytic (PEC) degradation activity than Bi2WO6 NAs photoelectrode. The PEC degradation rate of NiFe−LDH/Bi2WO6 NAs photoelectrode is 2.1 times and 4.7 times that of Bi2WO6 NAs photoelectrode under simulated solar light illumination and visible light illumination, respectively. This work proposes a new approach to construct highly efficient photoelectrode for contaminant purification.

AbstractWater electrolysis over a wide pH range offers promising technology for hydrogen production, which requires highly stable and active electrocatalysts for the hydrogen evolution reaction (HER). Herein, polyallylamine (PA)‐functionalized ultrafine rhodium nanoparticles (Rh−uNPs) uniformly anchored on three‐dimensional graphene aerogel (GA) nanocomposites (PA@Rh−uNPs/GA) are synthesized by using a facile surface adsorption‐chemical reduction method at room temperature. Physical characterization shows that the PA@Rh−uNPs/GA nanocomposites have three‐dimensionally porous architecture and that PA@Rh−uNPs with a 1.3 nm size are uniformly dispersed on the GA surface. Electrochemical measurements show that the molecular weight of PA affects the HER activity of PA@Rh−uNP nanocomposites. The molecular weight‐optimized PA@Rh−uNPs/GA nanocomposites with 10 % Rh mass show higher HER activity than the commercial 20 % Pt/C electrocatalyst over a wide pH range, which originates from proton or water enrichment at the electrode/solution interface due to the specific function of −NH2 groups at PA molecules.

AbstractIntroductionFractional flow reserve (FFR) measured after percutaneous coronary intervention (PCI) has been identified as a surrogate marker for vessel related adverse events. FFR can be derived from standard coronary computed tomography angiography (CTA). Moreover, the FFR derived from coronary CTA (FFRCT) Planner is a tool that simulates PCI providing modeled FFRCT values after stenosis opening.AimTo validate the accuracy of the FFRCT Planner in predicting FFR after PCI with invasive FFR as a reference standard.MethodsProspective, international and multicenter study of patients with chronic coronary syndromes undergoing PCI. Patients will undergo coronary CTA with FFRCT prior to PCI. Combined morphological and functional evaluations with motorized FFR hyperemic pullbacks, and optical coherence tomography (OCT) will be performed before and after PCI. The FFRCT Planner will be applied by an independent core laboratory blinded to invasive data, replicating the invasive procedure. The primary objective is to assess the agreement between the predicted FFRCT post‐PCI derived from the Planner and invasive FFR. A total of 127 patients will be included in the study.ResultsPatient enrollment started in February 2019. Until December 2020, 100 patients have been included. Mean age was 64.1 ± 9.03, 76% were males and 24% diabetics. The target vessels for PCI were LAD 83%, LCX 6%, and RCA 11%. The final results are expected in 2021.ConclusionThis study will determine the accuracy and precision of the FFRCT Planner to predict post‐PCI FFR in patients with chronic coronary syndromes undergoing percutaneous revascularization.

AbstractOne main approach to computational analysis of microbiome sequences is to first align against a reference database of annotated protein sequences (NCBI‐nr) and then perform taxonomic and functional binning of the sequences based on the resulting alignments. For both short and long reads (or assembled contigs), alignment is performed using DIAMOND, whereas taxonomic and functional binning, followed by inter‐ active exploration and analysis, is performed using MEGAN.

Emotional eating across different eating disorders and the role of body mass, restriction, and binge eating

Published: March 2021

AbstractObjectiveDifferent subtypes of eating disorders (ED) show dysfunctional eating behaviors such as overeating and/or restriction in response to emotions. Yet, systematic comparisons of all major EDs on emotional eating patterns are lacking. Furthermore, emotional eating correlates with body mass index (BMI), which also differs between EDs and thus confounds this comparison.MethodInterview‐diagnosed female ED patients (n = 204) with restrictive (AN‐R) or binge‐purge anorexia nervosa (AN‐BP), bulimia nervosa (BN), or binge‐eating disorder (BED) completed a questionnaire assessing “negative emotional eating” (sadness, anger, anxiety) and “happiness eating.” ED groups were compared to BMI‐matched healthy controls (HCs; n = 172 ranging from underweight to obesity) to exclude BMI as a confound.ResultsWithin HCs, higher BMI was associated with higher negative emotional eating and lower happiness eating. AN‐R reported the lowest degree of negative emotional eating relative to other EDs and BMI‐matched HCs, and the highest degree of happiness eating relative to other EDs. The BN and BED groups showed higher negative emotional eating compared to BMI‐matched HCs. Patients with AN‐BP occupied an intermediate position between AN‐R and BN/BED and reported less happiness eating compared to BMI‐matched HCs.DiscussionNegative emotional and happiness eating patterns differ across EDs. BMI‐independent emotional eating patterns distinguish ED subgroups and might be related to the occurrence of binge eating versus restriction. Hence, different types of emotional eating can represent fruitful targets for tailored psychotherapeutic interventions. While BN and BED might be treated with similar approaches, AN‐BP and AN‐R would need specific treatment modules.
Can current farmland landscapes feed declining steppe birds? Evaluating arthropod abundance for the endangered little bustard (Tetrax tetrax) in cereal farmland during the chick‐rearing period: Variations between habitats and localities

AbstractAgriculture intensification threatens farmland bird populations because, among other reasons, it reduces the availability of food resources required to rear their offspring. In our study, we sampled and analyzed total arthropod abundance, biomass and richness, and orthopteran and coleopteran abundance and biomass in different agricultural habitats (alfalfa fields, stubble fields, grazed fields, and field margins) across 4 study localities with different levels of agriculture abandonment–intensification, comparing between areas used and not used by one of the most threatened farmland birds in Europe, the little bustard (Tetrax tetrax), during the chick‐rearing season. Field margins were the taxonomically richest habitat, while alfalfa fields presented significantly higher total arthropod abundance and biomass than other habitats. All arthropod variables were the highest in the localities with clear conservation‐focused agrarian management, and the lowest in the most intensive one. Areas used by little bustards had higher orthopteran and coleopteran abundance and biomass than nonused areas, except for coleopteran biomass in grazed fields. These results highlight the relevance of these arthropods for the species, the importance of dry alfalfa fields as food reservoirs in this critical time of year, the food scarcity in sites where agrarian management disregards farmland bird conservation, and the role of stubbles as providers of food resources during the chick‐rearing season in areas used by the species. The adequate management of alfalfa fields and stubbles to provide those key resources seems crucial to improve little bustard breeding success.
The influence of competing root symbionts on below‐ground plant resource allocation

Abstract

Plants typically interact with multiple above‐ and below‐ground organisms simultaneously, with their symbiotic relationships spanning a continuum ranging from mutualism, such as with arbuscular mycorrhizal fungi (AMF), to parasitism, including symbioses with plant‐parasitic nematodes (PPN).

Although research is revealing the patterns of plant resource allocation to mutualistic AMF partners under different host and environmental constraints, the root ecosystem, with multiple competing symbionts, is often ignored. Such competition is likely to heavily influence resource allocation to symbionts.

Here, we outline and discuss the competition between AMF and PPN for the finite supply of host plant resources, highlighting the need for a more holistic understanding of the influence of below‐ground interactions on plant resource allocation. Based on recent developments in our understanding of other symbiotic systems such as legume–rhizobia and AMF‐aphid‐plant, we propose hypotheses for the distribution of plant resources between contrasting below‐ground symbionts and how such competition may affect the host.

We identify relevant knowledge gaps at the physiological and molecular scales which, if resolved, will improve our understanding of the true ecological significance and potential future exploitation of AMF‐PPN‐plant interactions in order to optimize plant growth. To resolve these outstanding knowledge gaps, we propose the application of well‐established methods in isotope tracing and nutrient budgeting to monitor the movement of nutrients between symbionts. By combining these approaches with novel time of arrival experiments and experimental systems involving multiple plant hosts interlinked by common mycelial networks, it may be possible to reveal the impact of multiple, simultaneous colonizations by competing symbionts on carbon and nutrient flows across ecologically important scales.
