AbstractWith the popular application of alternating current/direct current (AC/DC) hybrid power grid, ultra‐high‐voltage (UHV) AC/DC cables of long‐distance and large‐capacity transmission systems have been strongly demanded. Voltage stabilizers are widely used to resist AC electrical tree of cross‐linked polyethylene (XLPE) insulation materials, but poor compatibility with polymer matrix limited improvement of DC insulation performance. In this research, the maleic anhydride‐modified 2,4‐dihydroxybenzophenone as a novel voltage stabilizer 4‐(4‐benzoyl‐3‐hydroxyphenoxy)‐4‐oxobut‐2‐enoic acid (MDVS) was synthesized to improve the electrical properties of XLPE. The XLPE‐g‐MDVS with different contents of MDVS was prepared, and both AC electrical properties and DC electrical properties were tested. The results indicate that the modified XLPE retain the characteristic of voltage stabilizer to resist AC electrical tree and improve breakdown strength, and to exhibit excellent DC insulation performance in a wide temperature range. In the comparison with the pristine XLPE, the graft of MDVS can significantly suppress space charge accumulation and decrease DC conductivity. At 70°C, the maximum amount of space charge density of XLPE‐g‐1.2wt%MDVS is 56.2% lower than that of XLPE, and the DC conductivity decreases by nearly two orders of magnitude. Furthermore, the DC breakdown strength of XLPE‐g‐1.2wt%MDVS materials exhibit higher than that of the pristine XLPE. In addition to the self‐excited energy dissipation of the voltage stabilizer, quantum chemical calculations demonstrated that the improvement of DC performance attributed to the deep traps introduced by MDVS.

AbstractLithium‐sulfur (Li−S) battery with the advantages of high theoretical capacity and low cost is a promising technology for advanced energy storage. However, poor conductivity of the sulfur cathode, huge volume expansion, shuttling effect and sluggish catalytic conversion of lithium polysulfide hinder its commercialization. Herein, a 3D hierarchical porous carbon loaded with atomically dispersed Fe‐N4 was developed as a sulfur cathode, which not only offers enhanced electronic conductivity, but also alleviates volume expansion. Moreover, density functional theory calculation results suggest that the Fe‐N4 sites are favorable to enhance the diffusion and promote the conversion of lithium polysulfide. Consequently, lithium‐sulfur battery with 3D hierarchical porous carbon as the sulfur cathode exhibit good capacity and cycling performance, where a high initial specific capacity of 1289.3 mAh g−1 can be delivered at 0.1 C, and a capacity loss of only 0.025 % per cycle can be achieved for 1000 cycles at 2.0 C.

AbstractFour highly oxygenated sesquiterpenoids, illimicranolides A (1) and B (2), and illicinolides E (3) and F (4), were obtained from the fruits of Illicium micranthum Dunn, as well as one known analog, illicinolide B (5). The chemical structures of 1–4 were determined comprehensively by 1D (1H and 13C) and 2D (HMBC, HSQC, 1H‐1H COSY, and ROESY) NMR, and HR‐ESI‐MS data. Structurally, compound 1 was an unprecedented sesquiterpenoid with a 5/5/6/5‐fused tetracyclic ring system and was the first seco‐prezizaane sesquiterpenoid featuring a 11,8‐γ‐lactone ring. Compounds 3 and 4 were the fifth and sixth examples of illicinolide‐type sesquiterpenoids. Moreover, compound 1 demonstrated neurotrophic activity of NGF‐induced PC12 cells with differentiation rate of 10.34 % at a concentration of 10 μM.

AbstractStructured catalysts made by additive manufacturing offer the capability to seamlessly scale heterogeneous catalysis from lab to production with minimal effort to reengineer the process at intermediate steps. They can be tailored to meet certain process demands for mixing, heat transfer and flow resistance, in order to overcome flow maldistribution, hotspot or pressure drop issues, generally associated with traditional packed bed systems. Herein we investigate the long‐term durability of 3D‐printed Pd catalytic static mixers for their use in the hydrogenation of 4‐nitrobenzoic acid.

BACKGROUNDThe salivary gland neoplasm of uncertain malignant potential (SUMP) category in the Milan System is diagnostically challenging. This study aims to validate a modified scheme for subcategorizing SUMP in a large multi‐institutional cohort.METHODSRetrospective review of salivary gland fine‐needle aspirations (FNAs) from 10 institutions were classified based on the Milan System. Cases diagnosed as SUMP with available cytology slides and surgical follow‐up were retrieved for review and subcategorized based on a modified scheme as follows: basaloid SUMP (B1: absent/scant nonfibrillary matrix; B2: presence of nonfibrillary/mixed‐type matrix), oncocytic/oncocytoid SUMP (O1: with mucinous background; O2: without mucinous background), and SUMP not otherwise specified (NOS).RESULTSA total of 742 (7.5%) cases from 9938 consecutive salivary gland FNAs were classified as SUMP. Among them, 525 (70.8%) had surgical follow‐up and 329 (62.7%) were available for review. The overall risk of malignancy (ROM) of SUMP was 40.4%. There were 156 cases (47.4%) subcategorized as basaloid SUMP with a ROM of 36.5%, 101 (30.7%) as oncocytic/oncocytoid SUMP with a ROM of 52.5%, and 72 (21.9%) as SUMP NOS with a ROM of 31.9%. The ROM of oncocytic/oncocytoid SUMP was significantly higher than basaloid SUMP (P = .0142) and SUMP NOS (P = .0084). No significant differences in ROM were noted between B1 and B2 (36.7% vs 36.4%, P = 1.0000) and O1 and O2 (65.2% vs 48.7%, P = .2349).CONCLUSIONSThe ROM of oncocytic/oncocytoid SUMP was 52.5% and significantly higher than that of basaloid SUMP (36.5%, P = .0142) and SUMP NOS (31.9%, P = .0084), whereas no significant differences in ROM were noted for cases with different types of extracellular matrix or background material.;

AbstractThe development of highly active, cost‐effective hydrogen‐evolving photocatalysts is of great significance to alleviate the escalating environmental pollution and depleting fossil fuel sources. Herein, a novel CdS/VS2 heterostructured nanoparticle is successfully synthesized for the photocatalytic hydrogen evolution reaction (HER) under visible‐light irradiation via a facile hydrothermal route. Experimental results demonstrate that VS2 can facilitate the absorption of visible light, enhance the electron transfer rate, as well as inhibit the recombination of photogenerated electron‐hole pairs on CdS photocatalyst. Moreover, the optimal CdS/VS2 (0.2 wt.%) hybrid exhibits prominent photocatalytic HER activity 16 times higher than the pristine CdS counterpart, even outperforming the 1 wt.% platinum‐loaded CdS. This work injects new impetus to explore efficient noble‐metal‐free cocatalysts of CdS photocatalyst for high‐efficiency photocatalytic H2 evolution.

AbstractThe crystal structure of a newly synthesized compound, [PbL(Ac)]2, (where L=2 (amino(pyrazin‐2‐yl) methylene) hydrazinecarbothioamide, Ac=acetate anion) exhibits a close contact between pairs of Pb atoms, suggesting a ditetrel bond, in addition to two Pb⋅⋅⋅O tetrel bonds, and two C−H⋅⋅⋅O H‐bonds. The presence of this ditetrel bond as an attractive component is confirmed by various quantum chemical methods. This novelty of this particular bond is its existence even in the absence of a σ‐hole on the Pb atom, which is typically considered a prerequisite for a bond of this type. From a wider perspective, a survey of the Cambridge Structural Database suggests this bond may be more common than was hitherto thought, with 44 examples of Pb⋅⋅⋅Pb contacts amongst a total number of 219 examples of T⋅⋅⋅T interactions in general (T=Si, Ge, Sn, Pb).

Abstractπ‐Conjugated molecular materials often exhibit interesting photoluminescence, redox, and optoelectronic properties that grant them utility as light‐harvesting materials in solar cells, as the emissive component of organic light‐emitting diodes, and as fluorescence sensors. Preparing dye conjugates by appending multiple dyes together to generate π‐conjugated molecules is a common strategy to enhance the properties of these materials as it often imparts traits that cannot be achieved by the building blocks independently. Herein, we report molecular materials that incorporate boron difluoride hydrazone (BODIHY) and triphenylamine (TPA) units that exhibit charge‐transfer character, dual‐emission, and aggregation‐induced emission. The title compounds have low‐energy absorption bands (λabs=455–493 nm) that are red‐shifted relative to BODIHYs with smaller π‐systems and exhibit dual‐emission in the solution, solid, and aggregate states. TPA–BODIHY (donor‐acceptor) conjugates show multiple reversible redox events and, in combination, the data presented herein indicate that there is electronic communication throughout the donor‐acceptor and acceptor‐donor‐acceptor π‐systems. These results are rationalized with the use of computational chemistry and solid‐state structural analysis. This study provides new opportunities for the design of molecular materials that are comprised of redox‐active photoluminescent dyes, including BODIHY, and their potential applications.

Abstractβ‐Sulfido sulfonyl fluoride and its derivatives have been gaining attention recently in the fields of medicinal chemistry and material science. The conventional method for the synthesis of functionalized alkyl sulfonyl fluorides requires several chemical transformations. Therefore, a direct establishment of such chemical structures remains challenging, and an efficient catalytic approach is highly desired. Herein a significant “on‐water” hydrophobic amplification was achieved, enabling a high‐turnover catalytic thia‐Michael addition to produce unprecedented β‐arylated‐β‐sulfido sulfonyl fluorides. Amounts as low as 100 ppm (0.01 mol %) of the phosphazene superbase were sufficient to successfully catalyze the reaction with excellent chemo‐/site‐selectivity and with optimal functional group tolerance. Several β‐arylated ethene sulfonyl fluorides were converted into thia‐Michael adducts up to >99 % yields. The mild conditions, high turnover, neutral pH, and scalability of the sustainable catalytic process benefit the preparation of potential pharmaceuticals (e. g., polyisoprenylated methylated protein methyl esterase inhibitors) and organic materials (e. g., electrolyte additives).
Persistence of a Ru3(μ‐CO)3(CO)5Cluster Bound to a PNNP “Expanded Pincer” Ligand in Different Protonation States

AbstractWe report the synthesis and characterization of Ru3(μ‐CO)3(CO)5‐type cluster complexes bound to a dinucleating PNNP ‘expanded pincer’ ligand. Each bidentate PN pocket of the ligand chelates a single ruthenium center of the cluster and can undergo deprotonation concomitant with dearomatization of its naphthyridine core. Although the cluster bearing a partially dearomatized ligand reacts with H2, we found no indication that this proceeds via a pathway involving metal‐ligand cooperativity.

AbstractMetal corrole catalyzed Baeyer‐Villiger oxidation reaction was successfully achieved for the first time. Among all tested Co, Mn, Fe and Cu complexes of 5, 10, 15‐Tris (pentafluorophenyl) corrole, Fe complex [Fe(tpfc)Cl] exhibited the best activity, and the highest yield was observed for six membered cyclic ketones. Preliminary results suggest that Fe(tpfc)Cl may act as an initiator for dehydrogenation of benzaldehyde to generate benzoyl radical, which will form peroxybenzoic acid under molecular oxygen atmosphere. The oxidation of Fe(tpfc)Cl catalyst by peroxybenzoic acid produces high‐valent iron‐oxo corrole intermediate. The iron‐oxo corrole is attacked by cyclohexanone to form a Criegee adduct, which will finally generate ϵ‐caprolactone product to finish the catalytic cycle. The 4 A‐MS additive may accelerate the production of perbenzoic acid and significantly improve the reaction yield.

AbstractBackground and ObjectiveIntensive interdisciplinary pain treatment (IIPT) for youth with high impact chronic pain has been found to be effective in improving child symptoms and functioning. However, it remains unclear how these interventions impact the parents' own well‐being, as well as cognitions and behaviours which are known to influence child pain and functioning. Thus, the current study sought to determine the effect of IIPT on parent mental health, cognitions and behaviours in parents of youth attending IIPT with their child.Databases and Data TreatmentA search of the electronic databases CINAHL, Ovid EBM Reviews, Embase, Medline, APA PsychINFO, Scopus and web of Science was conducted. Studies were included if they comprised at least 10 parents of patients aged 9–22 with nonmalignant chronic pain attending an IIPT and were written in English.ResultsA random‐effects model was used to pool the standardized mean change (SMC) across seven prepost studies. At discharge, IIPT participation was associated with small to moderate improvements in direct parental outcomes (general mental health, anxiety, depression and parenting stress), a moderate improvement in pain catastrophizing and large improvements in psychological flexibility and parenting behaviours. Most improvements were maintained at follow‐up. The risk of bias of all studies was rated as serious and the certainty of the evidence as low, suggesting limited confidence in the estimates.ConclusionsAlthough parents appear to benefit from attending an IIPT with their child, RCTs are needed to substantiate the effect of these interventions on important aspects of parent well‐being and functioning.

Published: May 2022

AbstractCommercial buildings are consuming an increasing amount of energy, and accurate load demand forecasting is critical for the reliable operation of power systems and the efficient use of resources. Therefore, in this paper, a short‐term commercial load forecasting model based on tunicate swarm algorithm (TSA) combined with an extreme learning machine (ELM) under peak‐valley features is proposed as a research case for a shopping mall in Romania. This paper's overall structure is divided into two steps. In the first step, the 24‐h day is divided into six periods by analyzing the daily load characteristics of the training set, and the peak and valley loads are obtained. The ELM optimized by TSA (TSA‐ELM) algorithm is then used to forecast the peak and valley values of the test set one day ahead. In the second step, the actual load, peak, and valley for the previous week of historical load are chosen using the maximum information coefficient (MIC). Following that, the MIC ≥ 0.8 features are added to the TSA‐ELM to achieve short‐term commercial electricity load forecasting. The results show that the PV (Peak & Valley)‐TSA‐ELM model proposed in this paper has higher prediction accuracy compared with other models. Taking ELM as an example, compared with the traditional ELM, the mean absolute error, root mean square error, and mean absolute percentage error of PV‐TSA‐ELM are reduced by 20.59%, 20.13%, and 19.19% on average in the three commercial data sets. The proposed model is validated with an industrial data set, and ideal results are obtained, which verifies the effectiveness and superiority of the proposed method.

AbstractIn the pump mode of pump‐turbine, cavitation usually happens in runners because of the local pressure drop on the blade leading‐edge. At over‐load, pressure drop and cavitation occur on the runner blade pressure side. In conventional studies, the spatial and temporal features of the blade pressure‐side cavitation are difficult to understand. In this study, the runner blade pressure‐side cavitation is studied in a pump‐turbine in pump mode at over‐load. Local low pressure and cavitation are found on runner blade pressure‐side at leading‐edge near shroud. Moreover, small‐scale gathering cavitation is also observed on the blade suction‐side with connecting the large‐scale pressure side cavity. As a breakthrough in flow analysis, the pulsation tracking network (PTN) method is applied to track the spatial and temporal features of cavitation. The time‐accumulated intensity, pulsation amplitude, frequency, and phase are analyzed for cavitation based on PTN. The stably‐gathering strong‐intensity cavitation sites are indicated by time‐accumulated intensity. Based on the pulsation amplitude contour, strong pulsating cavitation is found on the edges of the gathering strong cavities. Frequency and phase analyses indicate the cavitation propagation along the blade‐to‐blade direction and reveal the reason of the connecting cavitation phenomenon. The spatial and temporal features of cavitation is well investigated.

AbstractMitochondrial E3 ubiquitin ligase 1 (MUL1) is a mitochondrial outer membrane‐anchored protein‐containing transmembrane domain in its N‐ and C‐terminal regions, where both are exposed to the cytosol. Interestingly the C‐terminal region has a RING finger domain responsible for its E3 ligase activity, as ubiquitin or in SUMOylation, interacting with proteins related to mitochondrial fusion and fission, cell survival, and tumor suppressor process, such as Akt. Therefore, MUL1 is involved in various cellular processes, such as mitochondrial dynamics, inter‐organelle communication, proliferation, mitophagy, immune response, inflammation and cell apoptosis. MUL1 is expressed at a higher basal level in the heart, immune system organs, and blood. Here, we discuss the role of MUL1 in mitochondrial dynamics and its function in various pathological models, both in vitro and in vivo. In this context, we describe the role of MUL1 in: (1) the inflammatory response, by regulating NF‐κB activity; (2) cancer, by promoting cell death and regulating exonuclear function of proteins, such as p53; (3) neurological diseases, by maintaining communication with other organelles and interacting with proteins to eliminate damaged organelles and; (4) cardiovascular diseases, by maintaining mitochondrial fusion/fission homeostasis. In this review, we summarize the latest advances in the physiological and pathological functions of MUL1. We also describe the different substrates of MUL1, acting as a positive or negative regulator in various pathologies associated with mitochondrial dysfunction. In conclusion, MUL1 could be a potential key target for the development of therapies that focus on ensuring the functionality of the mitochondrial network and, furthermore, the quality control of intracellular components by synchronously modulating the activity of different cellular mechanisms involved in the aforementioned pathologies. This, in turn, will guide the development of targeted therapies.

AbstractTrait rumination is the tendency to overthink and focus on negative emotions and events and is related to a number of psychological disorders and maladaptive behaviors including nonsuicidal self‐injury (NSSI). The purpose of this study was to conduct a meta‐analysis of the relationship between trait rumination and NSSI behaviors. Results from 60 samples showed small effect sizes between trait rumination and NSSI engagement, NSSI frequency, and the number of methods used to self‐injure in cross‐sectional samples. Results from 13 samples showed small effect sizes between trait rumination and NSSI engagement and NSSI frequency in longitudinal samples. Moderator analyses indicated that this relationship is similar whether the type of rumination is depressive or not and is generally consistent across different ages, genders, and ethnicities. These results help clarify the role of trait rumination as a risk factor for NSSI.
