Published: September 2023

AbstractThe construction of chiral superstructures through the self‐assembly of non‐chiral polymers usually relies on the interplay of multiple non‐covalent bonds, which is significantly limited by the memory ability of induced chirality. Although the introduction of covalent crosslinking can undoubtedly enhance the stability of chiral superstructures, the concurrent strong constraining effect hinders the application of chirality‐smart materials. To address this issue, we have made a first attempt at the reversible fixation of supramolecular chirality by introducing dynamic covalent crosslinking into the chiral self‐assembly of side‐chain polymers. After chiral induction, the reversible [2+2] cycloaddition reaction of the cinnamate group in the polymer chains can be further controlled by light to manipulate inter‐chain crosslinking and decrosslinking. Based on this photo‐programmable and dynamic chiral fixation strategy, a novel pattern‐embedded storage mechanism of chiral polymeric materials was established for the first time.

The improvement of high‐Z‐based metallic nanostructures as radiosensitizers with high monolithicity and versatility by superadditive therapeutic track and the good protective effect is considerable, but they are limited by some problems such as nonideal selectivity for the target tissue. In this study, nanosystems were developed to enhance the efficacy of radiotherapy and reduce cancer cell survival based on innovative gold (Au) functionalized oxygen‐single‐walled carbon nanotubes (O‐SWCNTs). We illustrate the use of folic acid (FA) as a targeting agent and bovine serum albumin (BSA) to stabilize the physiological environment and increase durability. The physical and chemical properties of the nanosystems were evaluated using transmission electron microscopy (TEM), selected area electron diffraction (SAED), dynamic light scattering (DLS), zeta potential, X‐ray diffraction (XRD), ultraviolet–visible (UV–Visible), and Fourier transform infrared (FTIR) techniques. Finally, the MTT assay was used to investigate the therapeutic effects of nanoparticles in the 4 T1 mouse breast cancer model in the presence and absence of X‐rays. So, the cancer cells experienced a more effective reduction in survival after receiving O‐SWCNTs‐Au‐BSA‐FA + 8 Gy than O‐SWCNTs‐BSA, Au‐BSA‐FA, and O‐SWCNTs‐Au‐BSA + 8 Gy groups.

Abstract

Freshwater mussels are declining throughout their range. Their important ecological functions along with insufficient levels of natural recruitment have prompted captive breeding for population augmentation and questions about the usefulness and applicability of such measures.
This article reviews the current state of captive breeding and rearing programmes for freshwater mussels in Europe. It considers the various species, strategies, and techniques of propagation, as well as the different levels of effort required according to rearing method, highlighting the key factors of success.
Within the last 30 years, 46 breeding activities in 16 European countries have been reported, mainly of Margaritifera margaritifera and Unio crassus. Some facilities propagate species that are in a very critical situation, such as Pseudunio auricularius, Unio mancus, and Unio ravoisieri, or multiple species concurrently. In some streams, the number of released captive‐bred mussels already exceeds the size of the remaining natural population.
Rearing efforts range from highly intensive laboratory incubation to lower intensity methods using in‐river mussel cages or silos. Most breeding efforts are funded by national and EU LIFE(+) grants, are well documented, and consider the genetic integrity of the propagated mussels. Limited long‐term funding perspectives, the availability of experienced staff, water quality, and feeding/survival during early life stages are seen as the most important challenges.
Successful captive breeding programmes need to be combined with restoration of the habitats into which the mussels are released. This work will benefit from an evidence‐based approach, knowledge exchange among facilities, and an overall breeding strategy comprising multiple countries and conservation units.
Data‐driven integral terminal sliding mode fault‐tolerant control for a collection of discrete‐time nonlinear systems
Authors: Hou Mingdong , Renming Yang , Li Guangye , Han Yaozhen 
Published: September 2023

AbstractThe manuscript proposes a data‐based integral terminal sliding mode control approach to determine fault‐tolerant control (FTC) concerning a class of discrete‐time nonlinear systems (DTNS) containing sensor fault. The proposed scheme can be readily implemented because it purely utilizes the input and output data of the system to employ a model called the compact form dynamic linearization (CFDL) data model, while the one‐step forward approximator is employed to estimate the fault function term in the system. Moreover, the fault diagnosis mechanism utilizes a time‐varying threshold with prescribed performance to judge whether the fault occurs. Hence, the problem of a standard fixed threshold used at the start‐up state of the control system is resolved. Then, the discrete‐time integral terminal sliding mode fault‐tolerant control (DITSM‐FTC) method is proposed. Concurrently, the sturdiness of the proposed method is assured by hypothetical investigation. When compared with the literature, the fundamental features of the proposed method are presented as follows: (1) the problem pertinent to fault utilizing a data‐driven model is resolved; (2) a fault diagnosis mechanism with prescribed performance is proposed, and (3) one step forward approximator is utilized to devise an estimation approach of fault detection. Finally, the efficacy of the proposed method is presented by running simulations.
Poly‐victimization of autistic adults: An investigation of individual‐level correlates
Authors: Gibbs Vicki , Hudson Jennifer L. , Pellicano Elizabeth 
Published: September 2023

AbstractAutistic people experience high rates of violence and victimization which is largely due to structural injustices, including stigma and social attitudes. Identifying and addressing systemic and structural factors is vitally important, however effecting change in embedded social structures is likely to take some time, even with concerted efforts. In the meantime, it is important to understand whether there are other individual‐level factors that may assist in developing preventative and protective strategies for autistic people. The current study investigated the role of individual‐level risk factors in the victimization of autistic people. Specifically, we examined whether characteristics that are common among autistic people that is, lower social competence, higher compliance and emotion regulation difficulties or more ADHD features (inattention, impulsiveness and hyperactivity) were associated with poly‐victimization in a community sample of 228 adults (118 autistic, 110 non‐autistic). Our results show that only ADHD features were predictive of poly‐victimization once socio‐demographic background variables (age, sexual orientation) were adjusted for. Group status was not a significant predictor in the model and there were no interaction effects between any of the characteristics and group status. These findings suggest that, regardless of whether a person is autistic, ADHD features may place individuals at higher risk of experiencing multiple forms of violence in adulthood. Further research using longitudinal designs and larger, diverse samples is needed. Furthermore, the regression model only accounted for about one‐third of the variance in poly‐victimization which highlights the importance of looking beyond individual‐level risk factors to structural and systemic factors that contribute to disproportionate victimization of autistic people.

AbstractBackgroundInformation regarding the risk of early pregnancy COVID‐19 vaccination on the development of major congenital anomalies in the offspring is still limited. Here, we study the association between any COVID‐19 vaccination during the 1st trimester and at least one major non‐genetic congenital anomaly in the offspring.MethodsWe used data from the Dutch Pregnancy Drug Register, an ongoing cohort study. We selected participants with a pregnancy that ended after at least 20 weeks gestation. Pregnant participants self‐reported their COVID‐19 vaccination status and the presence of congenital anomalies in the offspring. We used logistic regression analyses to study the association between 1st trimester COVID‐19 vaccination (gestational week 2 + 0 to 12 + 6) and the risk of at least one major non‐genetic congenital anomaly in the offspring. Clustering of anomalies on the ICD10 level by 1st trimester COVID‐19 vaccination status was explored using Fisher exact tests.ResultsWe included 3721 participants of whom 795 (21.4%) were COVID‐19 vaccinated during the 1st trimester. The percentage of participants who gave birth to a child with at least one major non‐genetic congenital anomaly was comparable between participants who were 1st trimester vaccinated (1.1%) and participants who were not (1.2%) (adjusted odd ratio 0.78 [95% confidence interval 0.35–1.71]). We found no clustering of major non‐genetic congenital anomalies by 1st trimester COVID‐19 vaccination status (p > .05).ConclusionsThere were no indications of an increased risk of major non‐genetic congenital anomalies in the offspring after maternal 1st trimester COVID‐19 vaccination. Our findings suggest COVID‐19 vaccines are safe during early pregnancy.

AbstractBackgroundStatins, metformin, and aspirin have been reported to reduce the incidence of hepatocellular carcinoma (HCC). However, the effect of their perioperative use on survival outcomes of HCC patients following curative liver resection still remains unclear.MethodThree hundred and fifty three patients with a first diagnosis of HCC who underwent curative liver resection were included. Propensity score matching analysis with a users: nonusers ratio of 1:2 were performed for each of the medications (statins, metformin, and aspirin). Overall survival (OS) and recurrence‐free survival (RFS) were evaluated and multivariable Cox proportional hazard analysis was performed.ResultsSixty two patients received statins, 48 patients used metformin, and 53 patients received aspirin for ≥90 days before surgery. None of the medications improved OS. RFS of statin users was significantly longer than that of nonusers (p = 0.021) in the matched cohort. Users of hydrophilic statins, but not lipophilic ones had a significantly longer RFS than nonusers. Multivariable analysis showed that statin use significantly improved RFS (hazard ratio [HR]: 0.41, 95% confidence interval [CI]: 0.17–0.97, p = 0.044). No difference was seen in RFS between metformin users and nonusers. Among patients with diabetes, RFS was nonsignificantly longer in metformin users than in non‐metformin users (84.1% vs. 60.85%, p = 0.069) in the matched cohort. No difference in postoperative RFS was seen between aspirin users and nonusers.ConclusionPreoperative use of statins in patients with HCC can increase RFS after curative liver resection, but metformin and aspirin were not associated with improved survival. Randomized controlled trials are needed to confirm the findings of the present study.

AbstractGiven the rise of marketing through social media influencers (SMIs), this study aimed to investigate the influences of source credibility and content validity factors on followers' attitudes and intention to purchase brands endorsed by SMIs through brand engagement and brand expected value. The study assessed the moderating effect of product–influencer congruency. Data were collected from 429 individuals in Iran and were assessed using the “partial least squares” (PLS) and “fuzzy‐set qualitative comparative analysis” (fsQCA) approaches. PLS results affirmed the significance of all direct relationships except the role of entertainment value on brand engagement and informativeness value on brand expected value. Product–influencer congruence positively moderated the effects of trustworthiness and expertise on brand expected value. fsQCA identified five solutions with various combinations of elements that lead to high purchase intention. The results of performing fsQCA revealed that three factors, namely attractiveness, entertainment value, and attitude, are necessary to achieve high purchase intention. fsQCA results challenged the PLS findings, indicating the importance of using an asymmetric approach in conjunction with PLS. Our study provides valuable insight for marketing influencers and practitioners on the importance of source credibility and content value factors in enhancing the effectiveness of SMI marketing activities and persuading customers to purchase endorsed brands.

AbstractEthylene glycol metal carboxylates are suited as low‐temperature precursors for M and MxOy nanoparticle formation, which are applicable in catalytic heterogeneous reactions including hydrogenations, hydrometalations or C,C cross‐couplings. For the synthesis of β‐oxo‐propyl and enol esters [Ru(CO)2(PPh3)2(O2CR)2] complexes are excellent homogeneous catalysts with high regioselectivities. Additionally, applications of the title complexes beyond catalysis are presented.
Systematic in situ Investigation of the Formation of NH3 Cracking Catalysts from Precursor Perovskites ABO3 (A=La,Ca,Sr and B=Fe,Co,Ni) and their Catalytic Performance
Authors: Gallus Simone , Weidenthaler Claudia 
Published: September 2023

AbstractThis work addresses the formation of ammonia (NH3) decomposition catalysts derived from perovskites ABO3 (A=La, Ca, Sr, and B=Fe, Co, Ni) precursors via operando synchrotron X‐ray diffraction experiments. During the reaction in NH3, the perovskite precursors are decomposed and the transition metals are reduced. Depending on their reduction properties, active metallic catalysts are formed in situ on La2O3 as support. The reduction behavior of the perovskites, formation of intermediate phases during activation, and catalytic performance was studied in detail. In addition, microstructure properties such as crystallite sizes and particle morphology were analyzed. Co‐/Ni‐based perovskites decomposed completely during activation to Co0/Ni0 supported on La2O3 while Fe‐based perovskites were fully stable but inactive in catalysis. This difference is due to varying electronic properties of the transition metals, e. g., decreasing electronegativity from Ni to Fe. With decreasing reducibility, the intermediate phases during activation formed more distinct. La3+ was partially substituted by Ca2+/Sr2+ in LaCoO3 to test for advantageous effects in NH3 decomposition. The best performance was observed using the precatalyst La0.8Sr0.2CoO3 with a conversion of 86 % (100 % NH3, 15000 mL g−1 h−1) at 550 °C.

Comprehensive SummaryCharge transport characterization of single‐molecule junctions is essential for the fundamental research of single‐molecule physical chemistry and the development towards single‐molecule electronic devices and circuits. Among the single‐molecule conductance characterization techniques, the single‐molecule break junction technique is widely used in tens of worldwide research laboratories which can generate a large amount of experimental data from thousands of individual measurement cycles. However, data interpretation is a challenging task for researchers with different research backgrounds, and the different data analysis approaches sometimes lead to the misunderstanding of the measurement data and even reproducibility issues of the measurement. It is thus a necessity to develop a user‐friendly all‐in‐one data analysis tool that automatizes the basic data analysis in a standard and widely accepted way. In this work, we present the XMe Code (Xiamen Molecular Electronics Code), an intelligent all‐in‐one data analysis tool for the comprehensive analysis of single‐molecule break junction data. XMe code provides end‐to‐end data analysis that takes in the original experimental data and returns electronic characteristics and even charge transport mechanisms. We believe that XMe Code will promote the transparency of the data analysis in single‐molecule electronics and the collaborations among scientists with different research backgrounds.

AbstractBackgroundThe frequency and severity of reactions in food‐allergic consumers exposed to unintentional food allergen contamination during production is unknown. To warn allergic consumers, it has been suggested for pre‐packaged foods to be precautionary labelled when the food allergen contamination may exceed the amount to which 1%–5% of the population could react (ED01–ED05). ED01 for hazelnut and milk have been estimated at 0.1 and 0.2 mg, respectively, by the Voluntary Incidental Trace Allergen Labelling (VITAL) initiative. The respective reference doses recommended by the FAO/WHO Codex consultation are 3 and 2 mg. We evaluated the reactivity to potential traces of milk and hazelnut allergens in allergen‐free pre‐packaged products by children affected by severe allergies to milk and hazelnuts.MethodsOral Food Challenges with commercially available hazelnut‐free wafer biscuits and milk‐free chocolate pralines were administered to patients with severe food allergies to hazelnut and cow's milk, respectively. Contamination levels of milk or hazelnut allergens were measured using chromatographic separation interfaced with triple quadrupole mass spectrometry.ResultsNo hazelnut allergic patient showed allergic reactions to exposure to biscuits, nor any milk allergic patient displayed allergic reactions to the dark chocolate praline. While no hazelnut trace was detected in biscuits, the praline was found to be contaminated by milk at concentrations ranging between 8 and 35 mg total protein/kg food. In our dose model, these amounts exceeded 1.5–10 times the VITAL ED01 and reached the threshold suggested by the FAO/WHO Codex consultation.ConclusionsUpon the consumption of food products available on the market, many patients with severe food allergies tolerate significantly higher doses of allergen than reference doses indicated in the VITAL system used for precautionary allergen labelling. These doses support the safety of the FAO/WHO recommended reference doses.

Published: September 2023

AbstractHeterogenous BPDC−RuO2−CeO2 catalyst derived from Ce−BPDC MOFs can successfully enable the oxidation of amines to nitriles under mild conditions (1 atm O2, H2O as a solvent, room temperature). The catalytic system has the good compatibility with benzylic and aliphatic amines. Lewis acid‐base pairs [Ru−O−Ce−Vö] formed by the combination of acidic oxygen vacancy and basic oxygen pair Ru−O−Ce on the surface of the catalyst is the key factor for the catalytic activity. The mechanical experiments indicate that amines adopt the step‐by‐step dehydrogenation process to nitriles in this transformation. Moreover, the catalyst could be recycled up to six times without the evident loss of catalytic activity and the change of morphology.

AbstractReplacing sluggish oxygen evolution reaction (OER) with electrocatalytic oxidation (ECO) of alcohols was a promising hotspot due to its advantages of requiring low potential, inhibiting mixing of gases, and forming value‐added products. In the ECO of alcohols process, Fe electron centers of Fe‐based layered double hydroxides (LDHs) can regulate the d band of LDHs overlap, optimize the active local structure of LDHs, and then enhance the electrocatalytic oxidation performance. In this work, CoxFey‐LDHs nanosheets with different ratios of Co/Fe were prepared for selective ECO of benzyl alcohol (BA) to benzoic acid (BAC). Comprehensive characterizations revealed that the adjustment of bandgap and OH species adsorption of CoxFey‐LDHs resulted in the appropriate thermodynamic driving force, which improved the electrical conductivity of CoxFey‐LDHs and enhanced their ECO of BA. Especially, the as‐prepared Co3Fe1‐LDH showed intriguing electrocatalytic activity and only required a potential of 1.51 V (vs. RHE) to achieve a total current density of 50 mA cm−2 in alkaline solution containing 10 mM BA with a conversion (96.79 %) of BA and selectivity (94.93 %) of BAC, which was 60 mV lower than that of OER. After six cycles, Co3Fe1‐LDH still achieved 94.74 % conversion of BA and 92.10 % selectivity of BAC without significant degradation.
