AbstractA PdII‐catalyzed, domino enantioselective desymmetrizative coupling of 7‐azabenzonorbornadienes with alkynylanilines is disclosed herein. This operationally simple transformation generates three covalent bonds and two contiguous stereocenters with excellent enantio‐ and diastereo‐selectivity. The resulting functionalized indole‐dihydronaphthalene‐amine conjugates served as an appealing platform to streamline the diversity‐oriented synthesis (DOS) of other valuable enantioenriched compounds. DFT calculations revealed that the two stabilizing non‐covalent interactions contributed to the observed enantioselectivity.

AbstractAmorphous inorganic perovskites have attracted significant attention as efficient electrocatalysts due to their unique structural flexibility and good catalytic activity. In particular, the disordered structure and a surface rich in defects such as oxygen vacancies can contribute to the superior electrocatalytic activity of amorphous oxides compared to their crystalline counterpart. In this work, we report the synthesis of LaCoO3, followed by an amorphization process through urea reduction with tailored modifications. The as‐synthesized catalysts were thoroughly tested for their performance in oxygen evolution reaction (OER), Remarkably, the amorphous LaCoO3 synthesized at 450 °C (referred to as LCO‐4) exhibits excellent OER catalytic activity. At an overpotential of 310 mV, it achieved a current density of 10 mA/cm−2, exceedingly fast to 1 A/cm−2 at an overpotential of only 460 mV. Moreover, LCO‐4 exhibited several advantageous features compared to pristine LaCoO3 and LaCoO3 amorphized at other two temperatures (350 °C, LCO‐3, and 550 °C, LCO‐5). The amorphized LCO‐4 catalyst showed a higher electrochemically active surface area, a key factor in boosting catalytic performance. Additionally, LCO‐4 demonstrated the lowest Tafel slope of 70 mVdec−1, further highlighting its exceptional OER activity. Furthermore, the long‐term stability of LCO‐4 is notably superior than pristine LaCoO3 (LCO‐P) and the other amorphized samples (LCO‐3 and LCO‐5). The enhanced catalytic activity of LCO‐4 can be attributed to its unique disordered structure, small crystallite size, and higher concentration of oxygen vacancies in the final catalyst.
Wet deposition of polycyclic aromatic hydrocarbons in a remote area of Central South China from 2014 to 2017
Authors: Li Yanxia , Duan Xiaoyong 
Published: November 2023

AbstractIn recent years, there has been a notable increase in the consumption of fossil energy, leading to a significant rise in environmental pollution, particularly in China due to its rapid development. This has resulted in the frequent occurrence of large‐scale fog and haze weather, highlighting the urgent need for environmental protection measures. To gain insights into the atmospheric conditions in China, an analysis was conducted on the wet deposition of polycyclic aromatic hydrocarbons (PAHs) in a remote region of Central South China from 2014 to 2017. The study revealed that the average concentrations and peak values of Ʃ16PAHs in 2014 and 2015 were considerably higher than those observed in 2016 and 2017. Furthermore, it was found that five‐ring PAH species were the predominant components during 2014 and 2015, indicating a shift in the main sources of PAHs. The peaks of Ʃ16PAHs were predominantly detected in samples collected during light rain in the winter, specifically on days without heavy rainfall. This can be attributed to the absence of heavy rain, which would otherwise reduce the concentration of air pollutants. Consequently, contaminants accumulated in the air are easily enriched in rainwater. The concentrations of Ʃ15Alkyl‐PAHs also exhibited a significant correlation with the number of rainfall days. Notably, a much higher annual average concentration of Ʃ15Alkyl‐PAHs was observed in 2017, which experienced fewer rainfall days. Coal combustion, petroleum sources, and vehicular emissions accounted for 58%, 12%, and 30% of the PAHs in the air, respectively. Despite improvements in air quality in China since 2016, it is crucial to address the elevated concentrations of PAHs in the atmosphere, particularly under adverse meteorological conditions characterized by reduced rainfall.

AbstractPrunella vulgaris has long been used in traditional medicine and is consumed as a tea in China. Here, the total phenolic and flavonoid concentrations of plants from different geographical regions were measured. It was found that the total phenolic acid concentration ranged from 4.15 to 8.82 g of gallic acid equivalent per 100 g of dry weight (DW), and the total flavonoid concentration was 4.67–7.33 g of rutin equivalent per 100 g DW. Antioxidant activities were measured using 2,2‐diphenyl‐1‐picrylhydrazyl and 2,2′‐azino‐bis‐(3‐ethylbenzothiazoline‐6‐sulfonic acid) diammonium salt, and the results ranged from 73.47% to 94.43% and 74.54% to 93.39%, respectively, whereas α‐glucosidase inhibition was between 75.31% and 95.49%. Correlation analysis showed that the total flavonoids in P. vulgaris had superior antioxidant and anti‐α‐glucosidase activities compared to the total phenolic compounds. The active components of P. vulgaris were analyzed using high‐performance liquid chromatography quadrupole time‐of‐flight mass spectrometry combined with both classical molecular networking and feature‐based molecular networking on the Global Natural Products Social platform, identifying 32 compounds, namely 14 flavonoids, 12 phenolic compounds, and 6 other chemical components. These results could provide useful information on the use of P. vulgaris as a functional tea.

AbstractTriclabendazole (TCB) is widely used for prevention and treatment of parasitic infections in animals. Improper use can result in drug residues in animal tissues and cause health problems to humans through consumption. A simple and reliable analytical method for the determination of TCB and its metabolites in bovine and goat muscle using liquid chromatography–tandem mass spectrometry (LC–MS/MS) was developed and validated. Analytes were extracted using acetonitrile and purified using enhanced matrix removal cartridge. Chromatographic separation was carried out on a BEH Shield RP18 column. The analytes were detected in positive‐mode electrospray ionization mass spectrometry using multiple reaction monitoring. Average recoveries of 96.1%–105.6% with coefficients of variation of 1.9%–8.4% were obtained at fortification levels of 0.5, 2.5, 25, and 50 μg/kg for TCB and 5.0, 25, 250, and 500 μg/kg for its metabolites (triclabendazole sulfoxide, triclabendazole sulfone, and keto‐TCB). A good linear regression was obtained with the mixed standard solutions in the range of 0.05–20 μg/L for TCB and 0.5–200 μg/L for its metabolites. The limit of quantification and limit of detection ranged from 0.05 to 0.75 μg/kg and from 0.1 to 1.5 μg/kg, respectively. Moreover, this method was successfully applied to 33 real samples.

Published: November 2023

AbstractThe emerging world cannot ignore circular bio‐economic development for long. A study of circular bioeconomy pointers at the local level is required to expedite the outgrowth of local economies. The narrative of “for the locals, by the locals, and at the local” is pursued in the study, by recognizing the research gaps concerning local economies' growth needs and their effective penetration into the advancement of circular bio‐economies, followed by the research objectives. The first question includes what role circular bio‐economic indicators play at the micro‐level in growing local economies and, second, emphasis on what role circular bio‐economic indicators play at the micro‐level to boost local economies. Semi‐structured interviews were conducted with circular organizations in Afro‐Asian states, resulting in seven themes derived by collating semantic and latent codes: patriotism, psychological safety, sustainable leadership, intrusive thoughts, ancestral footprints, waste valorization, and developing green brand evangelists. The study and findings seek to contribute to micro‐level circular bioeconomy indicators. Theoretical ideas, practical applications, and limitations are acutely discussed, exfoliating the developed world's conventional waste and residual sustainable outcomes covered till now in the circular bioeconomy literature.
Community arts, identity and recovery: A realist review of how community‐based arts activities enables the identity change recovery process from serious mental illness
Authors: Peters Louisa Anne , Gomersall Tim , Booth Andrew , Lucock Mike 
Published: November 2023

AbstractIdentity has been empirically established as a recovery process from serious mental illness (SMI) yet is often overlooked within intervention evaluations. Community arts presents one such intervention with emerging evidence illustrating the potential for recovery to occur within this context. However, research indicates numerous mechanisms may be involved in the identity recovery process, making it difficult to determine what works, for whom and in what context. The current review aimed to generate new theories to explain how, why and in what context community arts enable the identity change recovery process for individuals with SMI. A realist review was conducted between January and September 2021, with 22 articles and reports reviewed and synthesised to develop a theory. A safe and empowering intervention context was found to be vital to activate three key mechanism pathways: (a) feeling in control of SMI through coping; (b) achieving acceptance through connectedness and (c) overcoming personal challenges. The outcome was the development of positive self‐awareness, which enables individuals to redefine identity beyond SMI through both social and personal identities. Novel insights are presented through theory development, utilising the Social Identity Approach to Health and Transformative Learning Theory to conceptualise the findings through a multi‐theoretical lens.

Published: November 2023

AbstractNew substituted imidazolidinone sulfonamides have been developed using a rational drug design strategy. Predictive QSAR models for the search of new antibacterials were created using the OCHEM platform. Regression models were applied to verify a virtual chemical library of new imidazolidinone derivatives designed to have antibacterial activity. A number of substituted imidazolidinone sulfonamides as effective antibacterial agents were identified by QSAR prediction, synthesized and characterized by spectral and elemental, and tested in vitro. Six studied compounds have shown the highest in vitro antibacterial activity against Gram‐negative E. coli and Gram‐positive S. aureus multidrug‐resistant strains. The in vivo acute toxicity of these imidazolidinone sulfonamides based on the LC50 value ranged from 16.01 to 44.35 mg/L (slightly toxic compounds class). The results of molecular docking suggest that the antibacterial mechanism of the compounds can be associated with the inhibition of post‐translational modification processes of bacterial peptides and proteins.

Published: November 2023

AbstractPorous organic polymers (POPs) have attracted substantial attentions over the years due to their exceptionally high specific surface areas, high chemical stability of the organic network and ease of surface functionalization with the desired organic groups. In this work, a triazine based POP (TrzPOP) was synthesized through Schiff base polycondensation reaction between a tetramine bearing triazine rings and phenolic–OH group rich dialdehyde. Ni nanoparticles (NiNP) synthesized independently were immobilized over TrzPOP to obtain the NiNP@TrzPOP composite catalyst. This TrzPOP possesses a high BET surface area of 1494 m2 g−1 and low band gap, which facilitates its role as visible light absorbent. NiNP@TrzPOP with N‐rich surfaces and phenolic–OH moieties displayed excellent photocatalytic activity in the CO2 photoreduction under mild reaction conditions. NiNP@TrzPOP composite selectively reduces CO2 to methanol. The turn over number (TON) for this photoreduction of CO2 under optimized reaction conditions is 270, which is considerably high comparing to other reported photocatalytic systems. Moreover, NiNP@TrzPOP composite catalytic system showed high recycling efficiency without noticeable decrease in its performance over five consecutive reaction cycles, suggesting its huge potential for large‐scale methanol synthesis from the renewable carbon source.
Activation of Glassy Carbon Surfaces by Alkaline Anodization Enhances Dopamine Adsorption and Electron‐Transfer Kinetics
Authors: Swinya Dalia L. , Martín‐Yerga Daniel , Walker Marc , Unwin Patrick R. 
Published: November 2023

AbstractSurface activation can increase the sensitivity of carbon electrodes for electrochemical detection of neurotransmitters, such as dopamine (DA). However, fully understanding the changes in DA behavior after electrode activation remains elusive. Herein, we use scanning electrochemical cell microscopy (SECCM) to investigate DA adsorption and electrochemistry on glassy carbon (GC) after anodization in alkaline media. Through localized microscale anodization to different extents (two distinct times and same potential), followed by spatially‐resolved SECCM, we achieve direct visualization of DA electrochemistry across unmodified and anodized GC regions, with complementary microscopy and spectroscopy unraveling the effects of co‐located carbon surface chemistry and structure. Our findings reveal that short anodization times (60 s) enhance DA adsorption, rapidly reaching nearly complete monolayer coverage. Longer anodization (300 s) induces further changes in electrochemical surface area so that although the DA surface concentration increased based on geometric area, it was smaller based on specific surface area. This work highlights that even small differences in surface properties after activation can significantly impact electrode performance for neurotransmitter sensing, and separating the individual contribution of chemical and topographical factors remains challenging. SECCM provides an excellent platform to assess activation methods in a high throughput format to help accelerate the discovery of optimal modified electrodes.

Published: November 2023

AbstractCyclic azobenzene‐BODIPY hybrids were synthesized via cyclization by 1) acid‐catalysed condensation of azobenzene‐bridged dipyrroles with 3,5‐di‐tert‐butylbenzaldehyde, 2) oxidation with DDQ, and 3) metalation with BF3 ⋅ Et2O. The structures of many cyclic hybrids have been confirmed by single crystal X‐ray analysis. The absorption spectra of the hybrids reveal the effective cyclic conjugation. The ultrafast measurements reveal that the photoexcited decays of these cyclic hybrids depend upon the ring size and connectivity.
Cellular and laminar architecture: A short history and commentary
Authors: Rockland Kathleen S. 
Published: November 2023

AbstractThe feedforward/feedback classification, as originally stated in relation to early visual areas in the macaque monkey, has had a significant influence on ideas of laminar interactions, area reciprocity, and cortical hierarchical organization. In some contrast with this macroscale “laminar connectomics,” a more cellular approach to cortical connections, as briefly surveyed here, points to a still underappreciated heterogeneity of neuronal subtypes and complex microcircuitries. From the perspective of heterogeneities, the question of how brain regions interact and influence each other quickly leads to discussions about concurrent hierarchical and nonhierarchical cortical features, brain organization as a multiscale system forming nested groups and hierarchies, connectomes annotated by multiple biological attributes, and interleaved and overlapping scales of organization.

Published: November 2023

AbstractImportanceQuantitative electroencephalography (qEEG) has been used in the neonatal intensive care unit (NICU) for several decades. Recent innovations have led to renewed interest in expanding its role in the NICU with the goal of improving both acute care of neonates in the NICU and longer‐term outcomes.ObservationsEEG in the NICU is primarily used to identify neonatal seizures. Sophisticated analysis of EEG can detect other acute neurological emergencies and provide additional information about short‐ and long‐term neurodevelopmental and epileptic prognosis. Using EEG for these additional findings may be limited by access to EEG resources and a constrained supply of neonatal neurophysiologists who can consistently evaluate unique neonatal EEG patterns.RelevanceQuantitative EEG analysis is a rapidly developing technology with the potential to augment and support the interpretation of neonatal EEGs. This review focuses on the status of qEEG use in the NICU for identification and prediction of seizures and use in neuroprognostication. It also examines areas of promise for bedside qEEG applications.

AbstractComorbidity between depression and anxiety is well‐established across various settings and cultures. We approached comorbidity from the network psychopathology perspective and examined the depression, anxiety/autonomic arousal and stress/tension symptoms in naturalistic clinical samples from Serbia, Italy and Croatia. This was a multisite study in which regularized partial correlation networks of the symptoms, obtained via self‐reports on the Depression Anxiety and Stress Scales‐21 (DASS‐21) in three cross‐cultural, clinical samples (total N = 874), were compared with respect to centrality, edge weights, community structure and bridge centrality. A moderate degree of similarity in a number of network indices across the three networks was observed. While negative mood emerged to be the most central node, stress/tension nodes were the most likely bridge symptoms between depressive and anxiety/autonomic arousal symptoms. We demonstrated that the network structure and features in mixed clinical samples were similar across three different languages and cultures. The symptoms such as agitation, restlessness and inability to relax functioned as bridges across the three symptom communities explored in this study. Important theoretical and clinical implications were derived.
