AbstractIt is widely accepted that solid‐state membranes are indispensable media for the graphene process, particularly transfer procedures. But these membranes inevitably bring contaminations and residues to the transferred graphene and consequently compromise the material quality. This study reports a newly observed free‐standing graphene‐water membrane structure, which replaces the conventional solid‐state supporting media with liquid film to sustain the graphene integrity and continuity. Experimental observation, theoretical model, and molecular dynamics simulations consistently indicate that the high surface tension of pure water and its large contact angle with graphene are essential factors for forming such a membrane structure. More interestingly, water surface tension ensures the flatness of graphene layers and renders high transfer quality on many types of target substrates. This report enriches the understanding of the interactions on reduced dimensional material while rendering an alternative approach for scalable layered material processing with ensured quality for advanced manufacturing.

Published: July 2022

AbstractERF‐related craniosynostosis syndrome type 4 (CRS4, OMIM #600775) is a rare autosomal dominant malformation syndrome, caused by pathogenic variants in the ERF gene and characterized by craniosynostosis, developmental delay, and dysmorphic features such as hypertelorism, exophthalmos, depressed nasal bridge, and retrognathia. So far, there are mostly individual reports and only a few descriptions of families with more than two affected patients, allowing statements about the penetrance of a certain variant and its variability only to a limited extent. In this study, we report an in‐depth analysis of the clinical course of six family members from three generations with the novel heterozygous nonsense variant c.286A>T (p.Lys96*) in the ERF gene. At the time of examination, all of the six patients showed mild dysmorphic features and brachydactyly, five were overweight/obese and had delayed speech development, and four were short in stature. Hyperactivity, a short concentration span and a history of learning difficulties were found in half of the affected family members. To this day, none of the patients developed increased intracranial hypertension that would require surgical intervention. This work provides further information on the expressive variability of an ERF variant in six members of one family and focuses on the need for close neuropediatric surveillance.

AbstractThe selective photo‐oxidation of biomass‐derived 5‐hydroxymethylfurfural (HMF) to 2,5‐furandicarboxylic acid (FDCA) is important due to its substitute‐role in polyester‐fabrication. Here, a titanium‐cluster based metal‐covalent organic framework nanosheet has been synthesized through the covalent‐coupling between Ti6‐NH2and benzotrithiophene tricarbaldehyde (BTT). The integration of them endows the nanosheet with a visible‐light‐adsorption region, effective electron‐hole separation‐efficiency and suitable photo‐oxidation ability. Specifically, its photo‐selectivity for HMF‐to‐FDCA can be >95 % with ≈100 % conversion, which is more than 2, 5, and 10 times higher than MOF‐901 (43 %), Ti6‐NH2(19 %) and under‐darkness (9 %), respectively. Notably, an O2‐based mechanism is proposed and the vital roles of Ti6‐NH2and BTT are verified by DFT calculations. This work might facilitate the exploration of porous‐crystalline‐catalysts for selective biomass‐valorization.

Published: July 2022

AbstractHerein, we report a new X‐type ligand, i.e., organic sulfonium bromide, for high‐efficiency CsPbBr3 and MAPbBr3 (MA=methylammonium) perovskite nanocrystals (PNCs). We first confirmed the facile synthesis of the titled ligands in N,N‐dimethylformamide at room temperature. By reacting dodecylmethylsulfide with allyl bromide, (3‐bromopropyl)trimethoxysilane, and 1,4‐dibromobutane, respectively, three representative ligands (named DAM, DSM, and DMM) are acquired. All of them result in CsPbBr3 and MAPbBr3 PNCs with near‐unity photoluminescence quantum yield (PLQY) and decent ambient stability (no less than 90 % PLQY after 2 months) using a room‐temperature ligand‐assisted reprecipitation technique. Among them, DSM and DMM endow CsPbBr3 PNCs with higher thermal/light stability arising from the cross‐linkable or bidentate ligand structure. Further, DSM‐CsPbBr3 PNCs can be incorporated into polystyrene through in situ thermal polymerization and the composite shows a record‐high PLQY of 93.8 %.

Published: July 2022

AbstractIn order to overcome the shortcomings of nanofiber membranes such as low mechanical properties and poor acid resistance, amino‐rich functionalized polyimide (PI)‐polyethyleneimine (PEI) fibers were successfully prepared in the study. The structure and morphology in each functionalization step were characterized by scanning electron microscopy (SEM), atomic force microscopy (AFM), static contact angle, attenuated total reflection Fourier transform infrared spectroscopy (ATR‐FTIR), and X‐ray photoelectron spectroscopy (XPS) measurements. The adsorption kinetics analysis showed that the adsorption process followed a pseudo‐second‐order model, and the adsorption isotherm could be described better by the Langmuir model indicating the adsorption process was mainly chemical and homogeneous monolayer adsorption. Furthermore, the maximum adsorption capacity based on the Langmuir model was about 50 mg g−1, and the calculated thermodynamic parameters demonstrated an endothermic process. Meantime, the PEI‐grafted PI fibers also exhibited good regeneration performance and stable tensile strength during recycling tests process. In the first 3 adsorption–desorption cycles, the removal efficiency and tensile strength of PI‐PEI fibers could be maintained up to 60.44% and 89.29% of the initial adsorption, respectively. This work achieved the function of removing Cr (VI) by combining the excellent high temperature resistance, acid resistance, and mechanical properties of PI fibers.

AbstractMit dem zementgebundenen Ultra‐Hochleistungsfähigen Faserverbund‐Baustoff UHFB steht ein neuartiger Baustoff zur Verfügung, der sich durch hohe mechanische Festigkeiten und Dauerhaftigkeit auszeichnet. UHFB eignet sich für die Erneuerung bestehender Stahlbetonbrücken. Aufgrund der Erfahrungen mit zahlreichen Anwendungen werden in diesem Aufsatz die grundlegenden Entwurfskonzepte zum Schutz und zur Instandsetzung und Verstärkung von Stahlbetonbrücken entwickelt. Diese betreffen die Verbesserung der Dauerhaftigkeit sowie die Verstärkung von Fahrbahnplatten und Brückenträgern. Anhand von drei kürzlich ausgeführten Projekten wird die praktische Umsetzung der Entwurfskonzepte illustriert. Dabei wird aufgezeigt, dass die Erneuerung von Stahlbetonbrücken mithilfe von UHFB auch hinsichtlich der Nachhaltigkeit von Bauwerken bedeutend ist, da die in der Stahlbetonkonstruktion bereits verbauten Baustoffressourcen weiter genutzt werden.

AbstractThe growing sensitivity of stakeholders towards health, food safety and environmental protection has pushed agri‐food companies to embrace a new way of doing business, making huge investments to reduce their impact on ecosystem. However, these efforts would be in vain if not properly communicated, especially to financial institutions and investors, as they are the fundamental and supportive stakeholders. Through non‐financial disclosure, indeed, this greater transparency would translate into benefits, such as creditworthiness, lower risks and costs of capital. From these considerations, this study aims at verifying to what extent the implementation of sustainability strategies can affect the overall cost of capital, observed in its dual form: debt and equity. In particular, through panel data analyses, it tested how non‐financial disclosure—measured by Bloomberg's disclosure scores—could influence the cost of capital of a sample of 73 international agricultural firms observed from 2015 to 2019. The results showed a significant and negative relationship, suggesting that a higher level of disclosure could be effective in lowering firms' financial burden. This study contributes to the literature on non‐financial disclosure and cost of capital as it studies this phenomenon in a sector in which previous research is limited.

AbstractThe low stability of the electrocatalysts at water oxidation (WO) conditions and the use of expensive noble metals have obstructed large‐scale H2 production from water. Herein, we report the electrocatalytic WO activity of a cobalt‐containing, water‐soluble molecular WO electrocatalyst [CoII(mcbp)(OH2)] (1) [mcbp2−=2,6‐bis(1‐methyl‐4‐(carboxylate)benzimidazol‐2‐yl)pyridine] in homogeneous conditions (overpotential of 510 mV at pH 7 phosphate buffer) and after anchoring it on pyridine‐modified fluorine‐doped carbon cloth (PFCC). The formation of cobalt phosphate was identified only after 4 h continuous oxygen evolution in homogeneous conditions. Interestingly, a significant enhancement of the stability and WO activity (current density of 5.4 mA/cm2 at 1.75 V) was observed for 1 after anchoring onto PFCC, resulting in a turnover (TO) of >3.6×103 and average TOF of 0.05 s−1 at 1.55 V (pH 7) over 20 h. A total TO of >21×103 over 8 days was calculated. The electrode allowed regeneration of∼ 85 % of the WO activity electrochemically after 36 h of continuous oxygen evolution.

AbstractThe oxygen evolution reaction (OER) activity of single‐atom catalysts (SACs) is closely related to the coordination environment of the active site. Oxygen‐coordinated atomic metal species bring about unique features beyond nitrogen‐coordinated atomic metal species due to the fact that the M–O bond is weaker than the M–N bond. Herein, a series of metal–oxygen–carbon structured low‐nucleus clusters (LNCs) are successfully anchored on the surface of multiwalled carbon nanotubes (M‐MWCNTs, M = Ni, Co, or Fe) through a foolproof low‐temperature gas transfer (300°C) method without any further treatment. The morphology and coordination configuration of the LNCs at the atomic level were confirmed by comprehensive characterizations. The synthetic Ni‐MWCNTs electrocatalyst features excellent OER activity and stability under alkaline conditions, transcending the performances of Co‐MWCNTs, Fe‐MWCNTs and RuO2. Density functional theory calculations reveal that the moderate oxidation of low‐nucleus Ni clusters changes the unoccupied orbital of Ni atoms, thereby lowering the energy barrier of the OER rate‐limiting step and making the OER process more energy‐efficient. This study demonstrates a novel versatile platform for large‐scale manufacturing of oxygen‐coordinated LNC catalysts.
Thermoelectric performance of Ni, Co, and Fe nanoparticles incorporated into their metal borates glassy matrices

Published: July 2022

AbstractHere, we present our current attempt to intrinsically dope Ni0, Co0, and Fe0 nanoparticles within NiII‐, CoII‐, and FeII‐borate glassy matrices, respectively. The system was prepared by one‐pot reaction of the desired MTII salt with excess NaBH4 through an in‐situ reduction and hydrolysis processes to afford metallic MT0 nanoparticles dispersed into the MT‐BO3 matrix. The composition and structural characteristics of these MT0:MT‐BO3 materials were identified by thermal oxidation, ATR‐IR, X‐ray powder diffraction, and magnetic techniques as glassy/amorphous borate matrices containing magnetic nanoparticles. The electrical conductivity (σ) of cold‐pressed discs of these metal‐doped composites shows that they behave as nonohmic semiconductors within the temperature range of 303 ≤ T ≤ 373 K suggesting a mixed electronic‐ionic conduction. However, their thermal conductivity (κ) occurs through phonon lattice vibration dynamics rather than electronic. The σ/κ ratio shows a steep non‐linear increase from 9.4 to 270 KV−2 in Ni0:Ni‐BO3. In contrast, a moderate‐weak increase is observed for Co0:Co‐BO3 and Fe0:Fe‐BO3 analogs. The obtained materials are examined for thermoelectric (TE) applications by determining their Seebeck coefficient (S) power factor (PF), figure of merit (ZT), and conversion efficiency (η%). All the TE data shows that Ni0:Ni‐BO3 (S, 80 μVK−1; PF, 97.7 mWm−1 K−1; ZT 0.54; η, 2.15%) is a better TE semiconductor than the other two MT0:MT‐BO3. This finding shows that Ni0:Ni‐BO3 is a promising candidate to exploit low‐temperature waste heat from body heat, sunshine, and small domestic devices for small‐scale TE applications.
Energy‐efficient model using optimal route discovery based on adaptive spider monkey optimization model

Published: July 2022

SummaryDuring the past few years, wireless sensor networks (WSNs) have created a substantial interest because of their capabilities namely, self‐healing and self‐organizing under restricted network resources. Numerous WSN‐based routing algorithms are implemented to perform well, but the energy consumption of every data packet and information loss is more. Due to the power restriction in the sensor nodes, energy consumption is regarded as the major issue in networks that need to be minimized to improve the network lifetime. Hence, to conquer these consequences, this paper aims to propose an adaptive spider monkey optimization (ASMO)‐based effective optimal routing path from various sensor nodes with enhanced network lifetime. Here an ASMO is employed in selecting an optimal routing path. In addition to this, the proposed ASMO algorithm is capable of selecting energy‐aware routes by energy consumption. It also chooses the routes with minimum end‐to‐end delay using the bare least hop count criteria, thus enhancing the network life span. The results of the proposed method are compared with other methods such as DMEERP, EGSMRP, EEIABC, and RACO. The results reveal that the proposed approach consumed less amount of energy; hence, network lifetime is more when compared with other approaches.
Wall model‐based diffuse‐interface immersed boundary method for simulation of incompressible turbulent flows
Authors: Du Yinjie , Yang Liming , Shu Chang , Wu Jie , Wang Yan 
Published: July 2022

AbstractIn this work, a method is proposed to simulate the high Reynolds number turbulent flows by combining the diffuse‐interface immersed boundary method (IBM) with different wall models. In this method, two auxiliary layers (a series of Lagrangian points) are set outside the wall: the reference layer and the enforced layer. The wall model is applied at the reference layer to calculate the wall shear stress and the boundary condition is implemented at the enforced layer. When implementing the boundary condition, the implicit velocity correction‐based IBM is used. This process requires the velocity at the enforced layer. To calculate the velocity at the enforced layer, the momentum equation is integrated along the normal direction of the wall to link the tangential component of the velocity to the wall shear stress predicted by the wall models, and the normal component of the velocity is approximately reconstructed by the parabolic distribution. In addition, the Reichardt's law combined with Spalding's formula is utilized to determine the integral length. Numerical experiments for the turbulent flows around the flat plate, the NACA0012 airfoil and the NACA23012 airfoil are carried out to verify the feasibility of this method.

Abstract
Fluid and bicarbonate secretion is a principal function of cholangiocytes, and impaired secretion results in cholestasis. Cholangiocyte secretion depends on peri‐apical expression of the type 3 inositol trisphosphate receptor (ITPR3), and loss of this intracellular Ca2+ release channel is a final common event in most cholangiopathies. Here we investigated the mechanism by which ITPR3 localizes to the apical region to regulate secretion. Isolated bile duct units, primary mouse cholangiocytes, and polarized Madin‐Darby canine kidney (MDCK) cells were examined using a combination of biochemical and fluorescence microscopy techniques to investigate the mechanism of ITPR3 targeting to the apical region. Apical localization of ITPR3 depended on the presence of intact lipid rafts as well as interactions with both caveolin 1 (CAV1) and myosin heavy chain 9 (MYH9). Chemical disruption of lipid rafts or knockdown of CAV1 or MYH9 redistributed ITPR3 away from the apical region. MYH9 interacted with the five c‐terminal amino acids of the ITPR3 peptide. Disruption of lipid rafts impaired Ca2+ signaling, and absence of CAV1 impaired both Ca2+ signaling and fluid secretion. Conclusion: A cooperative mechanism involving MYH9, CAV1, and apical lipid rafts localize ITPR3 to the apical region to regulate Ca2+ signaling and secretion in cholangiocytes.
Does emotional restraint or exuberance get you the job? How and when enthusiasm intensity is related to perceived job suitability

Published: July 2022

AbstractScholars have identified that interviewers prefer applicants who are both emotionally restrained and exuberant. To reconcile these inconsistent results, we investigated how the magnitude of applicants' expressed enthusiasm influences interviewer perceptions of job suitability. In two experimental studies with recruiters in China, we show that expressing intense as opposed to mild enthusiasm reduces applicants' chances to be perceived as suitable for the job (Study 1). We further demonstrate that expressions of intense enthusiasm do not always undermine their perceived job suitability but can also lead to a positive interview outcome. We find that the negative consequences of intense enthusiasm are explained by interviewer perceptions of decreased appropriateness, whereas the positive consequences are driven by interviewer perceptions of the applicant's attraction to the organization (PAAO; Study 2). We also report how interviewer trait information processing motivation (IPM) influences the way applicants expressing intense enthusiasm are evaluated. Only interviewers with low trait IPM interpret applicants' intense enthusiasm as less appropriate. We propose to incorporate the social signaling character of emotions in future theorizing and research on nonverbal communication in job interviews.

Published: July 2022

AbstractVegetation plays a crucial role in gully headcut erosion. However, little is known about how grass influences runoff hydraulics, soil erosion and headcut erosion processes. A series of rainfall and scouring experiments were conducted on four plots to elucidate the effect of the density of Agropyron cristatum (L.) Gaertn (planting spaces: 20 × 20 cm2, GA1; 15 × 15 cm2, GA2; 10 × 10 cm2, GA3; bare land as control, BL) on runoff hydraulics and soil erosion during gully headcut erosion. The velocity, Reynolds number (Re), runoff shear force (τ) and stream power (ω) of the BL increased exponentially with time (P < 0.01). However, for the grassland, most parameters increased linearly with time (P < 0.01). The Froude number (Fr) of the BL and grassland significantly decreased linearly and exponentially, respectively, with time (P < 0.01). For τ, the grass tableland needed to develop for a period of time to restrain it. The runoff of the BL tableland and gully head was supercritical turbulent, while that of the grassland was more dispersed. The existence of a gully head increased the jet velocity by 2.97%–67.19%, which increased the dispersion degree of the runoff. The runoff energy showed a significant exponential increase with time (P < 0.05). Compared with that of the BL, the energy consumption of the runoff from the grassland increased by 4.10%–31.81%. During gully headcut erosion, the BL was primarily cut down to the tableland by runoff, while the grassland was cut down to the headwall by on‐wall flow. As the density increased, the benefit of sediment reduction increased, reaching a maximum of 66.79%. The collapse of the BL primarily occurred in the upper part of the headwall during the early experimental stage. The frequency and space–time ranges of the collapse of the grassland were larger than those of the BL. The gravity erosion types of the BL were headwall collapse and gully bank collapse, while those of the grasslands were headwall collapse and root‐soil composite collapse.
