Authors: Luo Zhouxin , Zhao Guoqiang , Pan Hongge , Sun Wenping 
Published: August 2022

AbstractStrong metal–support interaction (SMSI) in supported metal catalysts, typically accompanied by the formation of encapsulation layers over metal nanoparticles, has drawn intense research attention owing to a variety of intriguing behaviors. In particular, recent years have witnessed enormous progress in constructing SMSI between novel components as well as in understanding the nature of SMSI. Notably, SMSI also provides substantial possibilities for designing and modulating advanced heterogeneous catalysts toward a wide range of applications. Therefore, a systematic and critical overview is highly desirable to highlight the recent advances in SMSI and to discuss its applications in heterogeneous catalysts. In this review, the formation process of SMSI is described based on the typical material systems, and then the surface energy minimization mechanism is discussed by fully taking account of new material systems as well as novel construction strategies. Moreover, the principles of using SMSI to control the activity, selectivity, and stability of supported metal catalysts are demonstrated with an emphasis on thermocatalysis and electrocatalysis. To conclude, personal perspectives on the opportunities and challenges for SMSI are provided.

AbstractBrown shrimp, Crangon crangon (L.), is the most valuable target of coastal fisheries in the southern North Sea. Annual landings exceeded 30,000 tons in the last decade, yielding up to 100 Mio Euro. The shrimp are boiled immediately after capture onboard the fishing vessel for preservation and easy peeling. After landing, the shrimp are collected by traders and exported for manual peeling. Only the muscle of the pleon is returned and sold as regional delicacy. The remains, comprising the cephalothorax, the shell of the pleon, and, in case, adhering eggs, account for up to 70% of the total body mass. This potential resource, for example as aquaculture feed, has not yet been considered for exploitation. In this respect, the fatty acid (FA) profile and the share of essential FAs are crucial quality factors. Since boiling alters the quality of shrimp, this study evaluates changes in the FA composition of shrimp muscle and remains by comparing frozen and boiled samples. Major FAs in C. crangon were the saturated palmitic acid (PA, 16:0), accounting for 16.6%–19.1% of total fatty acids (TFAs), and the long‐chain polyunsaturated FAs (LC‐PUFAs) eicosapentaenoic acid (EPA, 20:5(n‐3), 16.1–21.6%TFA) and docosahexaenoic acid (DHA, 22:6(n‐3), 11.5–13.6%TFA). Frozen muscle and frozen remains showed similar FA profiles. Boiling changed the FA profile. PA, EPA, and DHA decreased by up to 25%, whereas palmitoleic acid 16:1(n‐7) and oleic acid 18:1(n‐9) increased by 2% to 3% each. Boiled muscle and boiled remains showed similar FA profiles. Despite the loss of FAs, the boiled shrimp remains are suggested to be a suitable PUFA supplement for aquaculture feeds, deserving further investigation.

AbstractObjectivesThe goal of the present research is to establish for the first time a hierarchy of sociodemographic factors according to their importance influencing birth seasonality.MethodsWe used Vital Statistics data on all births registered in Spain in the period 2016–2019. Differences in the degree of seasonality between sociodemographic groups (defined by maternal age, maternal marital status, maternal education, birth order, maternal job qualification, maternal employment status, maternal location population size, and maternal country of birth) were first examined with descriptive techniques. Secondly, analysis through alternative Data Mining techniques determined the association between sociodemographic factors and birth seasonality and the factors importance rank.ResultsThose factors related to maternal labor status (employment status, job qualification, and education) were found to be the most relevant influencing birth seasonality. It was found that the overall seasonal pattern in Spain was driven by lower skilled employed mothers, in contrast with not employed or high skilled employed mothers, who showed a different or weaker seasonality. Finally, we found that a change in the rhythm pattern has taken place in the last decades in Spain.ConclusionsBirth seasonality is to a large extent related to maternal employment status. Employed mothers, normally more affected by the seasonality of work calendar than the unemployed, show higher conception rates structured around holidays. This may indicate that the observed change of seasonal pattern in Spain in the last decades, as in other European countries, may be specifically driven by the progressive higher participation of women in labor market.

AbstractBackgroundDespite the growing number of studies on direct participation labor‐management practices, little is known about the role of their different discretionary degrees (delegation or consultation) and topics in their relationship with the psychosocial work environment by occupational groups.MethodsCross‐sectional study on the relationship between direct participation and work‐related psychosocial risks (using COPSOQ‐ISTAS21 v3) on a representative sample of the salaried and wage‐earning employees in Spain (n = 1807). Prevalence ratios were calculated using adjusted Poisson regression models, controlling for 10 other labor‐management practices, sex, and age, and stratified by occupational group.ResultsThe use of direct participation was either associated consistently with a healthier psychosocial work environment (mostly in manual occupations, which presented twice as many positive associations as nonmanual occupations, and of greater strength, mostly in the control and social support dimensions) or there were no significant associations (mostly among nonmanual occupations and in relation to work pace). More frequent and stronger associations were observed when consultation and delegation were used in combination. If used separately, consultation achieved better results among manual occupations and delegation among nonmanual occupations. Direct participation topics were not important for results in manual occupations whereas results were better on tactical (vs. operational) issues in nonmanual occupations.ConclusionsDirect participation does not change power structure, but it may be a useful intervention at the company level to reduce work‐related psychosocial exposures and associated diseases among workers in manual occupations, and consequently for decreasing occupational exposures and health inequalities.

AbstractEEF1A2 is a gene whose protein product, eukaryotic translation elongation factor 1 alpha 2 (eEF1A2), plays an important role in neurodevelopment. Reports of individuals with pathogenic variants in EEF1A2 are rare, with less than 40 individuals reported world‐wide, however a common feature is the association of the variant with developmental and epileptic encephalopathy. Thus far, there have been limited reports of other organ systems or body functions affected by variants in this gene. Here, we present a case of a child with EEF1A2‐related disorder who presented at 3 months of age with hypotonia, microcephaly, failure to thrive, and respiratory insufficiency with central apneas requiring respiratory support. Our case highlights the notion that the respiratory system may be highly implicated in EEF1A2‐related disorder, allowing for better phenotypic characterization of the disorder.

AbstractKabuki syndrome (KS) is a rare disorder characterized by distinct face, persistent fingertip pads, and intellectual disability (ID) caused by mutation in KMT2D (56%–76%) or KDM6A (5%–8%). Thirty‐seven children aged 1–16 years who followed for median of 6.8 years were included in this study, which aimed to investigate the genetic and clinical characteristics of KS patients. KMT2D and KDM6A were evaluated by sequencing and multiplex‐ligation‐dependent probe amplification in 32 patients. Twenty‐one pathogenic variants in KMT2D, of which 17 were truncated and nine were novel, one frame‐shift novel variant in KDM6A were identified. The molecular diagnosis rate was 68.7% (22/32). In the whole‐exome sequencing analysis performed in the remaining patients, no pathogenic variant that could cause any disease was detected. All patients had ID; 43.2% were severe and moderate. We observed that facial features that became more prominent with age were enough for a possible diagnosis of KS in infancy. The frequencies of facial features, cardiac and renal anomalies, short stature, microcephaly, and epilepsy did not differ depending on whether they had truncating or nontruncating variants or were in variant‐negative KS‐like group. This study has expanded clinical features of the disease, as well as identified new variants in genes causing KS.
Olefin–Borane Interactions in Donor–π–Acceptor Fluorophores that Undergo Frustrated‐Lewis‐Pair‐Type Reactions
Authors: Oshimizu Ryo , Ando Naoki , Yamaguchi Shigehiro 
Published: August 2022

AbstractOlefin–borane π‐complexes have been postulated as intermediates for the addition of frustrated Lewis pairs (FLP) to olefins. In the present study, we have employed this weak interaction to modulate the electronic properties of boron‐based π‐electron materials. A series of donor–π–acceptor (D–π–A) fluorophores that contain an alkenyl‐bridged diarylboryl group is synthesized. A crystallographic analysis revealed that the olefin and boron moieties are held in close proximity. Upon addition of a Lewis base to a solution of these D–π–A fluorophores, an FLP‐type addition occurs with concurrent significant changes in the absorption and emission properties. The FLP‐type reaction shifts the reaction site from the Lewis‐acidic boron atom to a carbocationic center, and thereby even facilitates a reaction with bulky Lewis bases. For example, a tricyclohexylphosphine adduct thus generated exhibits temperature‐dependent reversible dissociation/association behavior. These results provide a design strategy for stimuli‐responsive emissive boron‐based materials.

AbstractCation ordering in ABX3 perovskites is important to structural, physical and chemical properties. Here we report discovery of CaCuFeReO6 with the tetragonal AA′BB′O6 double double perovskite structure that was previously only reported for A′=Mn compositions. CaCuFeReO6 occurs in the same phase field as CaCu3Fe2Re2O12 demonstrating that different A‐cation ordered peroskites may be obtained in the same chemical system. CaCuFeReO6 has ferrimagnetic order of Fe, Re and Cu spins below TC=567 K, in contrast to Mn analogues where the Mn spins order separately at much lower temperatures. The magnetoresistance of CaCuFeReO6 displays low‐field “butterfly” hysteresis with an unusual change from negative to positive values as field increases. Many more AA′BB′O6 double double perovskites may be accessible for A′=Cu and other divalent transition metals at high pressure, so the presently known phases likely represent only the “tip of the iceberg” for this family.

AbstractThe access to full performance of state‐of‐the‐art Li‐ion batteries (LIBs) is hindered by the mysterious lithium plating behavior. A rapid quantified lithium plating determination method compatible with actual working conditions is an urgent necessity for safe working LIBs. In this contribution, the relationship between electrical double layer (EDL) capacitance and electrochemical active surface area (ECSA) of graphite anodes during the Li‐ion intercalation and Li plating processes is unveiled. We propose an operando lithium plating determination method based on the dynamic capacitance measurement (DCM) test. Reasonable selection of alternating current (AC) frequency protects the anodic responses from the interference of cathodic responses, which allows DCM to be applied in practical LIBs. The onset of lithium plating can be quantitatively traced, demonstrating the promise for real‐time operando determination for lithium plating in a working battery.

AbstractArtificial photocatalysis offers a clean approach for producing H2O2. However, the poor selectivity and activity of H2O2production hamper traditional industrial applications and emerging photodynamic therapy (PDT)/chemodynamic therapy (CDT). Herein, we report a C5N2photocatalyst with a conjugated C=N linkage for selective and efficient non‐sacrificial H2O2production in both normoxic and hypoxic systems. The strengthened delocalization of π‐electrons by linkers in C5N2downshifted the band position, thermodynamically eliminating side H2evolution reaction and kinetically promoting water oxidation. As a result, C5N2had a competitive solar‐to‐chemical conversion efficiency of 0.55 % in overall H2O2production and exhibited by far the highest activity under hypoxic conditions (698 μM h−1). C5N2was further applied to hypoxic PDT/CDT with outstanding performance in apparent cancer cell death and synchronous bioimaging. The study sheds light on the photosynthesis of H2O2by carbon nitrides for health applications.

AbstractZn‐based aqueous batteries have attracted much attention because of their high theoretical‐capacity, safety, and low‐cost, yet the H2‐evolution, qualification or inhibition mechanism investigations that are closely related to the dendrite‐growth are rare and challenging. Herein, a series of zincophilic metal‐covalent organic frameworks (e.g., Zn‐AAn‐COF, Zn‐DAAQ‐COF, and Zn‐DAA‐COF) have been explored as model‐platforms to manipulate the H2‐evolution and Zn2+flux. Best of them, Zn‐AAn‐COF based cell only produces 0.002 mmol h−1 cm−2 H2, which is >2 orders of magnitude lower than bare Zn. Noteworthy, it affords high stability for 3000 cycles (overpotential, <79.1 mV) at 20 mA cm−2in symmetric‐cell and enhanced cycling‐stability up to 6000 cycles at 2000 mA g−1in the assembled full‐battery. Besides, mechanistic characterizations show that Zn‐AAn‐COF can enhance the energy‐barrier of H2‐evolution and homogenize the ion‐distribution or electric‐filed to achieve high performance.

AbstractDNA nanotechnology has provided credible approaches for assembly of three‐dimensional (3D) lattices with complex patterns. However, the symmetries are strictly dependent on their initial configurations and difficult to alter via non‐thermal treatments. While switchable nucleic acid structures have been employed to construct deformable DNA motifs, it remains challenging to arrange them anisotropically in 3D lattices to trigger directed collective shape transition and dynamic symmetry conversion. In this work, we used octahedral DNA origami frames to synthesize four DNA origami lattices by placing the pH‐reactive i‐motif sequences in the desired dimensions. Thereinto, lattices with an anisotropic design can switch between simple cubic (SC) and simple tetragonal (ST) upon pH change. Small angle X‐ray scattering (SAXS) results reveal the feasibility of obtaining 3D lattices with sensitive responses to external stimuli, expanding the way to obtain low‐symmetry lattices.

AbstractRheological study plays a significant role in hollow fiber membrane spinning process and membrane structure regulation. In this work, the rheological behaviors of polyethersulfone (PES) spinning solutions added the polyvinylpyrrolidone (grade of PVP‐K30, PVP‐K60, and PVP‐K90) were systematically investigated by rotational rheometry to understand how the PES membrane structure changes. Results show that PVP of variable molecular weights change the rheological properties of PES spinning solution, such as the viscosity (ηa), non‐Newtonian index (n), flow activation energy (Eη), structural viscosity index (∆η), storage modulus (G′), and loss modulus (G′′). The mixture with PVP‐K30 exhibits optimal spinnability but the finger‐like membrane structure is undesirable for the hemodialysis. The rheological behaviors of PES/PVP‐K60 and PES/PVP‐K90 reveal that increasing shear rate and temperature are effective ways to improve the spinnability of the mixture and the membrane structure is regulated. Meanwhile, the addition of PVP‐K60 or PVP‐K90 at their critical concentration to the PES solution can fabricate a hollow membrane with a sponge‐like structure. Combining spinnability and membrane structure, PVP‐K90 is a suitable additive for the hemodialysis membrane.

AbstractInsulated gate bipolar transistor (IGBT) is the core of electric energy conversion and circuit control, which is widely used in the field of electric vehicles. Higher service temperature, higher power density, and higher operating voltage are the tendency for IGBT in which packing materials have to possess more stable temperature resistance and better insulating properties. In this work, cyanate ester (CE) and polyhedral oligomeric silsesquioxanes (POSS) are introduced into epoxy with various filling ratio to improve the dielectric and thermal properties. The curing process of every system is determined by non‐isothermal differential scanning calorimetry (DSC). N and Si element distribution mappings indicate that there are good compatibility between POSS, CE, and epoxy. The dielectric test shows that the dielectric constant decreases from 4.34 to 2.84 at 1 MHz and from 4.76 to 2.93 at 1 kHz when the filling ratio is 60 wt%. Meanwhile, the DC breakdown strength increases from 172.7 to 286.4 kV/mm. Furthermore, the glass transition temperature (Tg) increases from 180 to 263°C and the yield of residual carbon increases from 6.2% to 23.7%. A new packing material, which can endure 250°C of operating temperature and has excellent dielectric properties has been synthesized.

Published: August 2022

AbstractUnderstanding the evolution of an epidemic is essential to implement timely and efficient preventive measures. The availability of epidemiological data at a fine spatio‐temporal scale is both novel and highly useful in this regard. Indeed, having geocoded data at the case level opens the door to analyze the spread of the disease on an individual basis, allowing the detection of specific outbreaks or, in general, of some interactions between cases that are not observable if aggregated data are used. Point processes are the natural tool to perform such analyses. We analyze a spatio‐temporal point pattern of Coronavirus disease 2019 (COVID‐19) cases detected in Valencia (Spain) during the first 11 months (February 2020 to January 2021) of the pandemic. In particular, we propose a mechanistic spatio‐temporal model for the first‐order intensity function of the point process. This model includes separate estimates of the overall temporal and spatial intensities of the model and a spatio‐temporal interaction term. For the latter, while similar studies have considered different forms of this term solely based on the physical distances between the events, we have also incorporated mobility data to better capture the characteristics of human populations. The results suggest that there has only been a mild level of spatio‐temporal interaction between cases in the study area, which to a large extent corresponds to people living in the same residential location. Extending our proposed model to larger areas could help us gain knowledge on the propagation of COVID‐19 across cities with high mobility levels.
