Authors: Geng Xinxin , Xing Yan , Huan Jinmu , Hou Yongping , Zheng Yongmei 
Published: December 2022

AbstractA novel integrative bioinspired surface with annular pattern and 3D wettable gradient (APWG) is proposed for fog collection via a simple needle‐face anodic oxidation strategy. The fog collection behaviors are studied on APWG with different pattern types. Such a surface can not only improve the fog droplet capture performance effectively owing to annular wettable gradient pattern, but also realize the fog droplet capture and convergence on different surfaces to accelerate the surface regeneration rate, leading to a further fog collection enhancement. The results of experiment observation and underlying mechanism analysis have certified that such a design can realize a continuous 3D fog collection model to enhance the fog collection efficiency, resulting in a 1345% increase compared to the original surface.

Published: December 2022

AbstractAn interfacial polymerization process is introduced for the fabrication of thermally stable cyclomatrix poly(phenoxy)phosphazenes thin‐film composite membranes that can sieve hydrogen from hot gas mixtures. By replacing the conventionally used aqueous phase with dimethyl sulfoxide/potassium hydroxide, a variety of biphenol molecules are deprotonated to aryloxide anions that react with hexachlorocyclotriphosphazene dissolved in cyclohexane to form a thin film of a highly cross‐linked polymer film. The film membranes have persistent permselectivities for hydrogen over nitrogen (16–27) and methane (14–30) while maintaining hydrogen permeances in the order of (10−8–10−7 mol m−2s−1Pa−1) at temperatures as high as 260 °C and do not lose their performance after exposure to 450 °C. The unprecedented thermal stability of these polymer membranes opens the potential for industrial membrane gas separations at elevated temperatures.

Published: December 2022

AbstractComplex 3D metallic nanostructures with large surface areas and broadband absorption are attractive candidates for efficient photocatalysis and spectroscopy. Here, hierarchical Au dendrites are self‐assembled over centimeter‐scales by electrodeposition and the plasmon modes are locally mapped using cathodoluminescence spectroscopy. A correlation between the spatial and spectral distribution of the plasmonic “hot‐spots” and the morphology of these structures are demonstrated. Electrodynamic simulations show that the spectra of the plasmon modes are determined by the local geometry of sharp features. Their performance as both surface‐enhanced Raman scattering (SERS) substrates and as photocatalysts for the N‐demethylation reaction of methylene blue is investigated. High hot‐spot densities result in larger SERS enhancement, while the sample with the lowest hot‐spot density has a reaction yield 136% larger than the sample with the highest density. These findings indicate that maximizing the hot‐spot density is not sufficient to optimize plasmonic substrates for all applications. The spectral and spatial distribution of the plasmon resonances will modify the hot electron generation efficiency and need to be considered for plasmon‐enhanced photocatalysis. This work extends the understanding of light–matter interactions in complex 3D structures and provides direction for the rational design of plasmonic architectures for different applications.

AbstractDeveloping memristor with photosensing behavior would facilitate the construction of an advanced neuromorphic computing framework for future sensing−memory−computing integrated system. Although the memristor has already got much attention, its optoelectronic sensing mechanism is still unclear, thus the enhancement is challenging. Herein, a MoS2 memristor is fabricated on the oxygen‐vacancy‐rich Bi1.5MgNb1.5O7 thin film. By combining the voltage stress and photoexcitation, the memristor, its photosensing property, and their correlation have been systematically studied. The results show that the interfacial oxygen vacancy can trap the photogenerated electron obeying the photogating effect which tunes the Fermi level of MoS2 and exhibits tunable hysteresis behavior. The photoexcitation mechanism has been studied showing wavelength and voltage‐dependent photosensing−memory performance. The responsivity can reach up to 2 × 1011 V W−1 at 550 nm illumination and the hysteresis ratio (ΔH/Vg), one of the factors determining the memory, can be modulated by 40 times, which is larger than for previous 2D materials‐based memristors. Contour maps of external quantum efficiency show illumination, voltage, and wavelength dependence where the value becomes larger at lower illumination power density and higher voltage. This study reveals the interfacial enhanced photosensing mechanism of MoS2 device and provides new way to enrich memristor performance.

Published: December 2022

AbstractA triboelectric nanogenerator (TENG) facilitates the advancement of self‐powered displacement sensors, which are important for many autonomous intelligent microsystems. However, the amplitude‐based displacement sensing of conventional TENG‐based sensors still suffers significantly from varying charge densities in harsh environments. Benefiting from the combination of intelligent signal processing algorithms and direct‐current TENG sensors, this study proposes an environmentally robust character‐based displacement sensing method that eliminates the influences of varying charge density in principle. The experimental results show that under drastically changing air humidity and other harsh environments, the sensing of threshold and maximum displacement has far superior consistency and stability than that of traditional amplitude‐based TENG sensors, providing a novel route to realize reliable self‐powered displacement sensing in environment‐variable applications.
Growth and tissue nutrient responses of adults of Sarracenia alata to prey exclusion, nutrient addition, and neighbor reduction
Authors: Holloway Jalen C. , Stephen Brewer J. 
Published: December 2022

AbstractPremiseCarnivorous plants are often associated with nutrient‐poor soils and fires. Fire can decrease available soil nitrogen (N) and increase light availability, thus potentially favoring carnivory if prey provide N. Prey can also be a source of phosphorus (P), however, and soil P‐availability often increases and competition for prey can decrease following fire. Carnivory thus might be more advantageous before fire when prey and/or soil P are more limiting.MethodsWe examined nutrient limitation of growth in a carnivorous plant, Sarracenia alata, in a wet pine savanna in southeastern Mississippi, USA. We measured growth and N:P tissue concentration responses of adult plants to a factorial arrangement of prey capture, neighbor reduction, and addition of N, P, and ash to the soil. We tested two hypotheses: (1) Prey provide N, and neighbor reduction and ash addition increase light and soil P and thus the benefit of carnivory; and (2) Prey provide P, neighbor reduction increases prey and/or P, and prey exclusion reduces growth the most when neighbors are not reduced.ResultsThe exclusion of prey reduced growth more when neighbors were not reduced, an effect that was ameliorated slightly by the addition of P to the soil (the P‐limitation hypothesis). Prey exclusion caused a decrease in tissue P when N was added to the soil.ConclusionsThe results of this study with adult plants differed from those of a previous study using small juvenile plants, suggesting a shift from light limitation to P and prey limitation with increasing size.

AbstractIntroductionDespite increasing evidence of a role of rare genetic variation in the risk of Alzheimer's disease (AD), limited attention has been paid to its contribution to AD‐related biomarker traits indicative of AD‐relevant pathophysiological processes.MethodsWe performed whole‐exome gene‐based rare‐variant association studies (RVASs) of 17 AD‐related traits on whole‐exome sequencing (WES) data generated in the European Medical Information Framework for Alzheimer's Disease Multimodal Biomarker Discovery (EMIF‐AD MBD) study (n = 450) and whole‐genome sequencing (WGS) data from ADNI (n = 808).ResultsMutation screening revealed a novel probably pathogenic mutation (PSEN1 p.Leu232Phe). Gene‐based RVAS revealed the exome‐wide significant contribution of rare coding variation in RBKS and OR7A10 to cognitive performance and protection against left hippocampal atrophy, respectively.DiscussionThe identification of these novel gene–trait associations offers new perspectives into the role of rare coding variation in the distinct pathophysiological processes culminating in AD, which may lead to identification of novel therapeutic and diagnostic targets.

AbstractDie elektrochemische Umwandlung von Nitrat in Ammoniak ist ein wichtiger und nachhaltiger Ansatz zur Wiederherstellung des weltweit gestörten Stickstoffkreislaufs. Die rationale Entwicklung von Katalysatoren für die Nitratreduktionsreaktion (NO3RR) auf der Grundlage eines detaillierten Verständnisses des Reaktionsmechanismus ist von großer Bedeutung. Wir berichten über einen Cu2O+Co3O4‐Tandemkatalysator, der die NH3‐Produktionsrate im Vergleich zu Co3O4 um das ≈2.7‐fache und im Vergleich zu Cu2O um das ≈7.5‐fache steigert. Am wichtigsten ist jedoch, dass wir einzelne würfelförmige Cu2O‐ und Co3O4‐Nanopartikel einzeln und zusammen auf Kohlenstoff‐Nanoelektroden platzieren, was einen Einblick in den Mechanismus der Tandemkatalyse ermöglicht. Die Struktur‐ und Phasenentwicklung der einzelnen Cu2O+Co3O4‐Nanowürfel während der NO3RR wird mit Hilfe der Transmissionselektronenmikroskopie an identischer Stelle belegt. Die Kombination von Einzelpartikel‐Elektrochemie mit präziser Nanopositionierung wirft ein direktes Licht auf die dynamische Umwandlung einzelner Katalysatorpartikel während der Tandemkatalyse.

AbstractDie Synthese und Reaktivität von Übergangsmetallverbindungen mit “nackten” Pnictogenatomen ist ein aktueller Forschungsgegenstand mit außergewöhnlichen Bindungsmustern in den erhaltenen Produkten. Innerhalb dieses Gebietes ist insbesondere das Koordinationsverhalten von Komplexen mit Pn‐ und Asn‐ (2≤n≤5) Einheiten Gegenstand intensiver Forschungen. Untersuchungen zu den schwereren Homologen wurden bisher kaum durchgeführt, da geringe Ausbeuten und eine nur mäßige Luftstabilität hohe Hürden darstellen. Nunmehr legen wir eine erste grundlegende Studie vor, die die Reaktivität metallorganischer Komplexe mit Sb‐Donoratomen gegenüber verschiedenen AgI‐Salzen adressiert. Diese Reaktionen führten zu 12 neuartigen Verbindungen als Monomere, Dimere sowie drei‐ und viergliedrige Ketten aus AgI‐Ionen, die in der Literatur bisher als unzugänglich galten. Interatomare Abstände sowie computergestützte Belege, die mit Hilfe verschiedener Methoden erhalten wurden, weisen auf Ag⋅⋅⋅Ag‐Wechselwirkungen in allen Komplexen hin, die mehr als ein AgI‐Ion enthalten.

Published: December 2022

AbstractThe transition metal‐catalyzed cross‐coupling reaction with Fischer metal carbene intermediates bearing an electron‐rich alkoxyl or siloxyl group remains a big challenge due to the lack of readily available corresponding carbene precursors. Herein, we report the coupling of alkynes with the Fischer‐type copper carbene species bearing aα‐siloxyl group, which could be in situ generated from acylsilanes catalytically under photoirradiation and redox‐neutral conditions. The side‐arm modified bisoxazoline (SaBox) ligands prove to be crucial for this coupling reaction, which provides the corresponding alkynyl alcohol in high yields with remarkable heterocycle tolerance and broad substrate scope.

AbstractDiesters are of fundamental importance in the chemical industry and are used for many applications, e.g. as plasticizers, surfactants, emulsifiers, and lubricants. Herein, we present a straightforward and efficient method for the selective synthesis of diesters via palladium‐catalyzed direct carbonylation of di‐ or polyols with readily available alkenes. Key‐to‐success is the use of a specific palladium catalyst with the “built‐in‐base” ligand L16 providing esterification of all alcohols and a high n/iso ratio. The synthesized diesters were evaluated as potential plasticizers in PVC films by measuring the glass transition temperature (Tg) via differential scanning calorimetry (DSC).

Published: December 2022

AbstractHydrophobic nano‐fumed silica (NFS) was incorporated in polyvinylidene fluoride (PVDF) hollow fiber (HF) membrane for improving direct contact membrane distillation (DCMD) performance. The NFS/PVDF mixed matrix hollow fiber membrane was fabricated by the phase inversion process. The potential effects of increasing the percentage of NFS additive (0–6 wt.%) in the dope solution on the hollow fiber membrane characteristics such as viscosity, membrane morphology, porosity, hydrophobicity, Fourier transformed infrared spectroscopy, and permeability were investigated. The performance outcomes showed that the dope solution incorporated with 1.5 wt.% NFS exhibited the most promising HF membrane for membrane distillation (MD). The optimal HF membrane demonstrated the highest flux through shorter and narrower finger‐like structure formation and targeted high porosity. The addition of NFS particle content in the dope solutions enhanced the hydrophobicity of the fabricated membranes while slightly decreasing the porosity due to increasing the viscosity of the dope solution. With a steady flux of 9.25 kg/m2 h compared with the neat membrane at 70°C/20°C of feed/permeate temperatures, 8 h operation, and above 99.9% salt rejection, this PVDF/NFS mixed matrix hollow fiber membrane could be of excellent potential and sustainability in desalination process through DCMD.

AbstractTo study the combustion characteristics and fire hazard of polystyrene building exterior wall thermal insulation materials, the combustion, fire, and pyrolysis characteristics of thermosetting polystyrene (TPS) insulation, graphite polystyrene (GEPS), and expanded polystyrene (EPS) are compared and analyzed using a cone calorimeter and a thermo‐gravimetric analyzer. From the structure and flame retardant components of thermal insulation board, their flame retardant mechanisms are described. Results show that in a nitrogen atmosphere, the pyrolysis range is 30–600°C. Only one weight loss stage in EPS and GEPS and two weight loss stages in TPS are observed. Comparison of the combustion characteristics of the three demonstrates that TPS has short ignition time, low fire performance index. This result indicates that TPS has the characteristics of good flammability and easy to explode. The smoke generation rate, total smoke production, time heat release index and total heat release of TPS are lower than those of EPS and GEPS. This result indicates that the fire thermal hazard and fire smoke risk of TPS are relatively small. Comparison of various indexes presents that the flammability and fire risk of TPS are evidently better than those of EPS and GEPS.

Published: December 2022

AbstractThe production of cyclic carbonates and (or) polycarbonates from the coupling of carbon dioxide (CO2) with epoxides is a practical strategy for CO2fixation. Chemically recycling of the polycarbonates is also urgently needed for sustainable development of plastics. Here a dinuclearβ‐diketiminato (BDI) methyl zinc complex((BDI‐ZnMe)2,1) is reported to achieve not only selective cyclic carbonates from cycloaddition of CO2tomeso‐CHO in the presence of cocatalyst, but also effective depolymerization of PCHC intotrans‐CHC. Thetrans‐CHC can be further transformed intocis‐CHC, thus demonstrating great application potentials of this strategy in CO2fixation and chemical recycling of plastics.

AbstractThis paper studies the stabilization problem for linear continuous‐time singular fractional‐order systems with the fractional‐order satisfying . New formulations of the admissibility for the closed‐loop system by dynamic output feedback controller are obtained using necessary and sufficient (linear matrix inequality) conditions, to generalize existing results in the literature for integer‐order systems. The derived results are validated by numerical examples demonstrating applicability and efficacy of the presented approach.

AbstractBackground and objectivesThe presence of acrylamide, a probable carcinogen, is a global concern for the baking industry. The reduction of free asparagine in wheat is an effective strategy to mitigate acrylamide formation. However, field‐based strategies for this purpose also affect gluten strength and bread quality. Therefore, we investigated the relationship between wheat free asparagine concentration, gluten strength and whole wheat bread quality for an extensive set of hard red spring wheat samples.FindingsGluten strength parameters negatively correlated to wheat free asparagine concentration and showed strong inverse correlations to wheat free asparagine concentration per unit mass of protein. Reducing free asparagine concentration in the wheat did not affect the quality of the bread.ConclusionsIn efforts to deliver wheat grains with a low acrylamide‐formation potential, wheat producers can apply strategies, for example, variety selection, that will reduce free asparagine without worries that gluten strength and bread quality will be impaired.Significance and noveltySafety concerns regarding free asparagine in wheat have elicited much attention from cereal scientists and the breadmaking industry. However, the effects of reducing free asparagine on gluten strength have not been systematically studied in the literature. This comprehensive study shows that there is an inverse relationship between gluten strength and wheat free asparagine concentration.

AbstractThe paired electrolysis coupling the reduction of CO2 to value‐added molecules like HCOOH with the oxidation of biomass‐derived 5‐hydroxymethylfurfural (HMF) to 2,5‐furandicarboxylic acid (FDCA) is one promising strategy of great economic and environmental benefits. Herein, a Ni(OH)2 anode for the selective oxidation of HMF to FDCA was fabricated, revealing the significant part of the membrane in electrocatalytic procedure. With the FDCA product as a di‐carboxylic acid ligand, one new bismuth‐based metal‐organic framework material was synthesized, which is capable of catalyzing the reduction of CO2 to HCOOH with over 95 % Faradaic efficiency (FE) and an average current density of 19.6 mA cm−2 at −1.2 V vs. reversible hydrogen electrode (RHE). With this inner relationship, paired electrolysis was conducted with cathodic potential fixed at −1.2 V vs. RHE, producing the HCOOH with 95.6 % FE and FDCA with 75 % FE in one single electrolyzer.
