Single‐Step Synthesis of NiI from NiII with H2
Authors: Takahashi Chiaki , Yatabe Takeshi , Nakai Hidetaka , Ogo Seiji 
Published: September 2023

AbstractChemists have long sought to regulate the reactivity of H2, to yield hydride ions, hydrogen atoms, or electrons on demand. One source of inspiration for achieving this control is [NiFe]hydrogenase ([NiFe]H2ase), which reacts with H2 to form various hydrogen active species such as NiIII hydride species, NiII hydride species, and NiI low‐valent species. Chemists have attempted to synthesize these hydrogen active species not only as models for the active species of [NiFe]H2ase, but also as electron transfer catalysts. However, the synthesis of NiI complex directly from H2 has not been reported. This paper reports the first example of a single‐step synthesis of a NiI complex, via reaction of a NiII complex with H2, stable for over 3 months at room temperature and we further demonstrate a reductive coupling of acridinium ions as part of a reaction cycle.

AbstractSeed‐mediated growth has been widely used to synthesize noble metal nanoparticles with controlled size and shape. Although it is becoming possible to directly observe the nucleation process of metal atoms at the single atom level by using transmission electron microscopy (TEM), it is challenging to control the formation and growth of seeds with only a few metal atoms in homogeneous solution systems. This work reports site‐selective formation and growth of atomic scale seeds of the Au nanoparticle in a nanospace of an organic cage molecule. We synthesized a cage molecule with amines and phenols, which were found to both capture and reduce Au(III) ions to spontaneously form the atomic scale seeds containing Au(0) in the nanospace. The growth reaction of the atomic scale seeds afforded Au nanoparticles with an average diameter of 2.0±0.2 nm, which is in good agreement with the inner diameter of the cage molecule.
Chalcogen Bond Catalysis with Telluronium Cations for Bromination Reaction: Importance of Electrostatic and Polarization Effects
Authors: Wang Yanjiang , Zhao Chang , Chen Wen‐Kai , Zeng Yanli 
Published: September 2023

AbstractRecently, chalcogen bond catalysts with telluronium cations have garnered considerable attention in organic reactions. In this work, chalcogen bond catalysis on the bromination reaction of anisole with N‐bromosuccinimide (NBS) with the telluronium cationic catalysts has been explored with density functional theory (DFT). The catalytic reaction is divided into two stages: the bromine transfer step and the proton transfer step. Based on the computational results, one can find the rate‐determining step is the bromine transfer step. Moreover, the present study elucidates that a stronger chalcogen bond between catalysts and NBS will give better catalytic performance. Additionally, this work also clarified the importance of the electrostatic and polarization effects in the chalcogen bond between the oxygen atom of NBS and the Te atom of the catalyst in this bromination reaction. The electrostatic and polarization effects are significantly influenced by the electron‐withdrawing ability of the substitution groups on the catalysts. Moreover, the structure‐property relationship between the strength of chalcogen bond, electrostatic effect, polarization effect and catalytic performance are established for the design of more efficient chalcogen bond catalysts.
Surface Activated Pyrolytic Carbon Black: A Dual Functional Sustainable Filler for Natural Rubber Composites
Authors: Abdul Sattar Mohammad 
Published: September 2023

AbstractThe significant rise in end‐of‐life tires (ELTs) globally poses immediate environmental and human health risks. Therefore, to promote ELTs recycling and to reduce tire industry carbon emissions, herein we present a facile approach for fine‐tuning the interfacial interactions between pyrolytic carbon black (P‐CB) obtained from ELTs and natural rubber (NR) matrix using phosphonium‐based ionic liquid (PIL). The reinforcing effect of PIL‐activated P‐CB was studied by replacing the furnace‐grade carbon black (N330‐CB) with varying PIL and P‐CB loadings. Adding PIL improved the filler dispersion and the cross‐linking kinetics with a substantially reduced zinc oxide (ZnO) loading. Considering the cross‐linking and viscoelastic properties, it was concluded that the composite, P‐CB/N330‐CB‐PIL (1.5)+ZnO (1) with half substitution of N330‐CB with P‐CB synergistically works with 1.5 phr PIL and 1 phr of ZnO resulting in improved dynamic‐mechanical properties with a minimal loss tangent value at 60 °C (tanδ=0.0689) and improved glass transition temperature (Tg=−38 °C) compared to control composite. The significant drop (~29 % lower) in tanδ could reduce fuel consumption and related CO2 emissions. We envisage that this strategy opens an essential avenue for “Green Tire Technology” towards the substantial pollution abatement from ELTs and reduces the toxic ZnO.

AbstractElectrochemical water splitting to generate hydrogen energy fills a gap in the intermittency issues for wind and sunlight power. Transition metal (TM) oxides have attracted significant interest in water oxidation due to their availability and excellent activity. Typically, the transitional metal oxyhydroxides species derived from these metal oxides are often acknowledged as the real catalytic species, due to the irreversible structural reconstruction. Hence, in order to innovatively design new catalyst, it is necessary to provide a comprehensive understanding for the origin of surface reconstruction. In this review, the most recent developments in the reconstruction of transition metal‐based oxygen evolution reaction electrocatalysts were introduced, and various chemical driving forces behind the reconstruction mechanism were discussed. At the same time, specific strategies for modulating pre‐catalysts to achieve controllable reconfiguration, such as metal substituting, increase of structural defect sites, were summarized. At last, the issues for the further understanding and optimization of transition metal oxides compositions based on structural reconstruction were provided.

Published: September 2023

AbstractAimsIn acute heart failure (AHF), kidney congestion is basic to treatment and prognosis. Its aetiology is manifold and quite unexplored in details mainly regarding the right heart to pulmonary circulation (Pc) coupling. We investigated the right heart to kidney interrelationship by Doppler renal flow pattern, right atrial dynamics, and right ventricular (RV) function to Pc coupling in AHF.Methods and resultsIn 119 AHF patients, echocardiographic and renal Doppler data were analysed. Univariate and multivariate regression models were performed to define the determinants of a quantitative parameter of renal congestion, the renal venous stasis index (RVSI). When grouped according to different intra‐renal venous flow patterns, no differences were observed in haemodynamics and baseline renal function. Nonetheless, patients with renal Doppler evidence of congestion showed a reduced RV function [tricuspid annular plane systolic excursion (TAPSE), S′‐wave velocity, and fractional area change], impaired RV to Pc coupling [TAPSE/pulmonary artery systolic pressure (PASP) ratio], and right atrial peak longitudinal strain (RAPLS), along with signs of volume overload [increased inferior vena cava (IVC) diameters and estimated right atrial pressure]. Univariate and multivariate regression analyses confirmed TAPSE/PASP, RAPLS, and IVC diameter as independent determinants of the RVSI. RVSI was the only variable predicting the composite outcome (cardiac death, heart failure hospitalization, and haemodialysis). An easy‐to‐use echo‐derived right heart score of four variables provided good accuracy in identifying kidney congestion.ConclusionsIn AHF, the renal venous flow pattern combined with a right heart study phenotypes congestion and clinical evolution. Keys to renal flow disruption are an impaired right atrial dynamics and RV–Pc uncoupling. Integration of four right heart echocardiographic variables may be an effective tool for scoring the renal congestive phenotype in AHF.

AbstractThe hydrohalogenation of olefins is one of the most straightforward methods to access alkyl halides. Despite safety hazards, using pure hydrogen halide gas remains the most atom economic way of performing hydrohalogenation reactions. In this work, we describe the solvent‐free hydro‐ and deuteriohalogenation of olefins using down to near‐stoichiometric amounts of hydrogen and deuterium halide gas. Two‐chamber reactors are employed as an enabling platform to access these reactive gases in a laboratory setting. Ex situ generation from inexpensive and readily available precursors provides on‐demand access to these gases (hydrogen chloride, deuterium chloride, hydrogen bromide, deuterium bromide, hydrogen iodide, and deuterium iodide) with precise stoichiometric control. Upon chemo‐ and regioselective conversion of the substrate, the halide products may be isolated without the need for any work‐up or purification steps making it a clean and labor‐, waste‐ and cost‐effective method.

Published: September 2023

AbstractBridge cable is an important force transmission component of bridge, but it is easy to be damaged during service, such as fatigue damage and corrosion damage, which seriously threatens the safety of bridge structure. Therefore, it is necessary to identify damage of cable force. Generally, the damage of cable force can be identified by the change of cable frequency. This paper establishes a cable force damage identification model based on Bayesian inference and uses Metropolis‐Hastings (MH) algorithm to solve the posterior probability function of unknown parameter. In the Bayesian inference model, the influence of the priori function of unknown parameters on the posterior probability distribution model is discussed. In the MH algorithm, the influence of different proposed distributions (Normal distribution, Gamma distribution and Weibull distribution) on the sampling results is discussed based on three numerical simulation studies, and the influence of burned sample proportion on the establishment of a posteriori distribution function is analyzed. Furthermore, the influence of monitoring noise data and missing data on cable force damage identification is considered, and the robustness of the proposed method is analyzed.

AbstractBackground and AimMetabolic syndrome (MetS) is a well‐known noncommunicable disease that plays a significant role in emerging other chronic disorders and following complications. MetS is also involved in the pathophysiology of numerous dermatological diseases. We aim to evaluate the association of MetS with the most prevalent dermatological diseases.MethodsA systematic search was carried out on PubMed, Science Direct, Web of Science, Cochrane, as well as the Google Scholar search engine. Only English case‐control studies regarding MetS and any skin disease from the beginning of 2010 up to November 15, 2022, were selected. The study was conducted based on the Preferred Reporting Items for Systematic Reviews and Meta‐Analysis (PRISMA).ResultsA total of 37 studies (13,830 participants) met the inclusion criteria. According to our result, patients with psoriasis, hidradenitis suppurativa (HS), vitiligo, androgenetic alopecia (AGA), and lichen planus (LP) have a higher chance of having MetS compared to the general population. Furthermore, people with seborrheic dermatitis (SED) and rosacea are more prone to insulin resistance, high blood pressure (BP), and higher blood lipids. After pooling data, the meta‐analysis revealed a significant association between MetS and skin diseases (pooled odds ratio [OR]: 3.28, 95% confidence interval: 2.62−4.10). Concerning the type of disease, MetS has been correlated with AGA (OR: 11.86), HS (OR: 4.46), LP (OR: 3.79), and SED (OR: 2.45). Psoriasis also showed a significant association but with high heterogeneity (OR: 2.89). Moreover, skin diseases and MetS are strongly associated in Spain (OR: 5.25) and Thailand (OR: 11.86). Regarding the metaregression model, the effect size was reduced with increasing age (OR: 0.965), while the size increased with AGA (OR: 3.064).ConclusionsMetS is closely associated with skin complications. Dermatologists and other multidisciplinary teams should be cautious while treating these patients to prevent severe complications resulting from MetS.
A novel treatment approach for traumatic scalp defects with exposed calvaria denuded of pericranium by combined application of low‐temperature plasma and negative pressure wound therapy: A case series
Authors: Ongkasuwan Pattana 
Published: September 2023

AbstractBackground and AimsTraumatic scalp defects with an exposed calvaria denuded of the pericranium are challenging to manage. In such cases, adjunctive therapies, such as milling the outer calvarial cortex and applying negative pressure wound therapy (NPWT), can promote granulation tissue. This case series describes the successful management of traumatic scalp defects after cortical craniectomy using a combination of low‐temperature plasma (LTP) and NPWT.MethodsThis is a retrospective single‐surgeon case series. Three patients with traumatic scalp wound defects underwent cortical calvarial bone removal after LTP combined with NPWT. LTP was applied to the diploic space of the calvaria weekly or twice weekly using BioPlasmaJet BPJ1 (BIOPlasma System: Model‐BioPlasmaJet System). Subsequently, NPWT was applied with a continuous pressure of 110 mmHg until good granulation tissue formation was achieved for skin graft placement.ResultsTwo males and one female were included, and the mean follow‐up duration was 7 (range 3–12) months. In addition, the average time to achieve good granulation tissue formation was 4 (2–6) weeks; all patients achieved successful split‐thickness skin grafting within 3 weeks after placement without signs of calvarial infection.ConclusionsThe combination of LTP and NPWT is a safe and effective treatment modality for scalp defects with exposed calvaria denuded of the pericranium resulting from trauma. Combining these two therapies may provide a synergistic effect that enhances granulation tissue formation and prevents local infections without complications.

Published: September 2023

AbstractKarst aquifers have complex structures and high heterogeneity, making it difficult to describe their hydrogeological characteristics. An essential tool for comprehending karst hydrogeology and identifying the hydraulic characteristics of the karst system is a quantitative analysis of the recession process of the karst spring hydrograph. The recession process of the spring hydrograph following a rainfall event can be utilized to assess the internal structure of the karst system as it relates to the karst aquifer's response to rainfall events. In this study, a laboratory physical experiment model is built based on typical karst hydrogeological circumstances, and a corresponding combined discrete‐continuum (CDC) numerical model is established, coupling conduit and matrix. The primary goal of this paper is to investigate how the recession process of the spring hydrograph responds to various rainfall events. Different rainfall intensities with the same rainfall duration and various rainfall intensities with the same rain amount are examples of rainfall patterns. The simulation results showed that the pattern of rainfall events affects the recession process of the spring hydrograph, and the recession coefficient of the corresponding recession stage, the proportion of water volume released by conduit and matrix with the different rainfall patterns are calculated and analysed, and the impact of rainfall events on the recession coefficient of spring hydrograph and the spring water composition has been explored. The research results can provide a reference and basis for the management of water resources in karst areas.

Published: September 2023

AbstractIndole derivatives are fundamental structural units in many bioactive compounds and molecular materials. The site‐selective C7‐functionalization of these moieties has been proven to be extremely challenging due to the inherent reactivity of the C2‐ and C3‐positions. Herein, we report the first electro‐C7‐alkenylation of indoles. This novel and sustainable methodology provides highly exclusive access to the C7‐position devoid of often toxic and expensive chemical oxidants. Moreover, an array of substrates was successfully alkenylated at the C7‐position, and versatile product diversification was achieved.

Authors: Afesorgbor Sylvanus Kwaku , Lim Sunghun 
Published: September 2023

AbstractThe COVID‐19 pandemic profoundly affected food security by disrupting supply chains through border closures Our study concentrates on South Asia and examines the interplay between COVID‐19, agri‐food trade, and inflation using monthly panel data spanning 2018–2021. Our findings demonstrate that the pandemic notably escalated food inflation in the region. Nevertheless, the robust interaction of agri‐food trade with COVID‐19 helped alleviate this effect. This underscores the significance of trade policies in controlling food inflation during the pandemic in South Asia.

Financial reporting complexities: Association with accounting expertise of board and audit committee
Authors: Siregar Sylvia Veronica , Harahap Siti Nurwahyuningsih 
Published: September 2023

AbstractThe purpose of our study is to examine the financial reporting complexity of listed firms in Indonesia and the association between the financial reporting complexity and the accounting expertise of boards (Board of Directors/BOD and Board of Commissioners/BOC) and audit committee members. We use samples of listed firms in Indonesia over the period from 2013 to 2019. We find that financial reporting complexity is negatively associated with the accounting expertise of the BOD, BOC, and audit committee. These results indicate that companies do not try to engage in higher accounting expertise to mitigate the unfavourable impact of financial reporting complexity and that companies tend to use the financial reporting complexity to obfuscate the financial reporting. The novelty of our study is developing an aggregate measure of the financial reporting complexity that has not been used in extant studies. We also have not found any previous studies examining this issue in emerging countries, including Indonesia. The previous study has examined similar issues in the USA, where the USA is a developed country with a high level of investor protection. The varying levels of investor protection may affect the results.

Published: September 2023

AbstractContracting is a skill used by genetic counselors (GCs) to establish a shared vision for the session. Ensuring that patients and GCs are aligned on expectations for the encounter allows GCs to meet patient needs and support patient autonomy. Although contracting is described in the practice‐based competencies (PBCs), the process has not been systematically observed in practice. We sought to further elucidate the skills used for contracting within genetic counseling sessions through directed content analysis of transcripts from 148 simulated prenatal and cancer genetic counseling sessions. An a priori codebook and rating scale were developed based on four contracting sample skills described in the PBCs: (a) describing the genetic counseling process, (b) eliciting client concerns, (c) applying client concerns to a session agenda, (d) modifying the agenda in response to emerging concerns. The rating scale described the quality of each skill on a 4‐point scale of “absent,” “minimal,” “adequate,” and “excellent.” The codebook and rating scale were pilot tested with 40% of transcripts (n = 60). Three authors independently coded and rated the final 60% of transcripts (n = 88), resolving discrepancies via a consensus process. We found that the four PBC skills were present in most sessions (88%–98%), and on average, GCs received “adequate” scores on all four skills. We also identified three additional components of contracting not described in the PBCs: assessing whether client concerns were met, inviting to interrupt, and providing opportunity for partner concerns. This study represents the first attempt to evaluate GC performance of a PBC during a genetic counseling session. Our findings demonstrate that the PBC sample contracting skills reflect practice and suggest that they can be used in assessment of the genetic counseling contracting process. This type of analysis could be adapted in the future to provide support for other standards of practice in the genetic counseling field.
