AbstractChemical doping is a significant means to modulate bandgap structures and optoelectronic properties of transition metal dichalcogenides (TMDCs). Herein, an Er3+/Yb3+ co‐doped WS2 monolayer with ultrahigh and tunable concentrations is successfully fabricated by in‐situ chemical vapor deposition (CVD) technique. The morphologies, thicknesses, components, and structures of the samples are systemically characterized by optical microscope, atomic force microscopy, Raman, X‐ray diffraction, X‐ray photoelectron spectroscopy, scanning electron microscope with energy dispersive spectrometer, and high‐resolution transmission electron microscopy, respectively. Photoluminescent peaks are enhanced significantly with red shifts, and the absorption is broadened to near‐infrared, implying a shrinked bandgap after RE co‐doping, which is consistent to the calculation results by density functional theory (DFT). The Er3+/Yb3+ co‐doped WS2 device demonstrates high carrier mobility, photocurrent, photoresponsivity, external quantum efficiency, and specific detectivity, which are approximately two orders of magnitudes compared with those of the pristine WS2 device. The values of photoresponsivity and specific detectivity approach 4.8 × 104 A W−1 and 5.5 × 1014 Jones, respectively, at 20 V bias and 1.77 mW cm−2 luminescence, which may refresh the records as has been reported. The excellent performances of the WS2 photodetector prove the effectiveness of Er3+/Yb3+ co‐doping for practical application in optoelectronics.

Published: November 2023

AbstractSpirooxindoles are privileged scaffolds in diverse bioactive natural products and pharmaceuticals, significant achievements for the construction of these molecules have thus been made in the past years. Among them, organocatalysis, in particular, nucleophilic Lewis base catalysis, has recently emerged as an efficient and reliable method for the preparation of diverse and valuable functionalized spirooxindoles. According to different kinds of nucleophilic catalysts, we summarize and classify three catalytic strategies; these are tertiary amine‐catalyzed cycloadditions, NHC‐catalyzed cycloadditions, and tertiary phosphine‐catalyzed cycloadditions, respectively. Through these methods, potential bioactive spirooxindole skeletons owning various functional groups can be produced to enrich the small organic molecule library. In this review, we describe a comprehensive and updated advances of nucleophilic Lewis base catalytic cycloaddition reactions for the construction of spirooxindoles. Meanwhile, the related mechanism and the application of these annulation strategies in natural product total synthesis will be highlighted in detail.

AbstractSulfonyl‐tethered N‐containing heterocycles are valuable building blocks in synthetic and pharmaceutical chemistry. Recently, the installation of fluoroalkanesulfonyl groups into heterocycles via the difunctionalization of alkenes still remains challenging. Herein in this work, an imino‐fluoroalkanesulfonylation of γ,δ‐unsaturated oxime esters has been achieved via photoredox/Cu dual catalysis. A variety of fluoroalkanesulfonyl‐tethered pyrroline derivatives have been readily synthesized in moderate to good yields under mild conditions.

Published: November 2023

AbstractResonant light scattering by mesoscale dielectric spheres has received enormous attention and found many interesting applications. The recently emerged field of Mesotronics provides novel opportunities for wavelength‐scaled optics and new fundamental aspects are still being uncovered. It has recently been demonstrated that high‐order Mie resonances can be excited in homogeneous low‐dissipation mesoscale dielectric spheres, leading to the generation of intense magnetic fields. This article describes a simple and effective way to drastically enhance the superresonance effect. Proof‐of‐principle results for the first time show that yet one more novel phenomenon of increasing the intensity of the magnetic field without changing the resonant Mie size parameter of the sphere by introducing an air cavity. In such a dielectric cenosphere (from two Greek words “kenos”‐hollow and “sphaira”‐sphere), by correct choice of the air cavity size, it is possible to increase the intensity of the electromagnetic fields at the poles of the sphere by an order of magnitude due to increasing of the amplitude of resonant partial wave coefficient.
Robust integration of fault estimation and sliding mode fault‐tolerant control for interconnected systems against sensor fault
Authors: Abdul‐Jaleel Noor Safaa , Shaker Montadher Sami 
Published: November 2023

AbstractThis paper provided a robust strategy for controlling nonlinear interconnected large‐scale systems subject to a sensor fault. The inherent challenge in controlling such systems is to sustain robust closed‐loop stability and performance in nonlinear interactions, faults, and exogenous inputs. A new closed‐loop structure has been devised to tackle this challenge by integrating the sliding mode controller with the unknown input observer. By exploiting the decoupling capability of the controller and observer, this integration ensures the robustness of the closed‐loop system against the simultaneous effect of interaction, fault, and disturbance. In this context, the unknown input observer has been constructed to supply the controller with an accurate sensor fault assessment despite additional unknown inputs. A novel approach is proposed for designing a decentralized fault‐tolerant control system that utilizes sliding mode control and proportional‐integral‐derivative controller tuning via a bacterial foraging optimization algorithm to compensate for the fault effect, leading to a robust output performance. The observer and controller gains are accomplished by utilizing the H∞ performance and linear matrix inequality formulation. The Lyapunov technique is used to demonstrate stability. A power system model emphasizes the proposed approach's robustness and effectiveness. The system performance with and without the proposed controller was compared, where the simulation results show a fast reaction to offset undesirable impacts, whereas the state estimation error approaches to zero in each subsystem.

Abstract2ʹ‐Fucosyllactose (2ʹ‐FL) which is well‐known human milk oligosaccharide was biotechnologically synthesized using engineered Corynebacterium glutamicum, a GRAS microbial workhorse. By construction of the complete de novo pathway for GDP‐L‐fucose supply and heterologous expression of Escherichia coli lactose permease and Helicobacter pylori α‐1,2‐fucosyltransferase, bioengineered C. glutamicum BCGW_TL successfully biosynthesized 0.25 g L−1 2ʹ‐FL from glucose. The additional genetic perturbations including the expression of a putative 2ʹ‐FL exporter and disruption of the chromosomal pfkA gene allowed C. glutamicum BCGW_cTTLEΔP to produce 2.5 g L−1 2ʹ‐FL batchwise. Finally, optimized fed‐batch cultivation of the BCGW_cTTLEΔP using glucose, fructose, and lactose resulted in 21.5 g L−1 2ʹ‐FL production with a productivity of 0.12 g L−1•h, which were more than 3.3 times higher value relative to the batch culture of the BCGW_TL. Conclusively, it would be a groundwork to adopt C. glutamicum for biotechnological production of other food additives including human milk oligosaccharides.
Brothers and sisters in arms: A mixed‐methods investigation of the roles played by military support and social identity processes in the mental health of veterans during the transition to veterancy

AbstractThe transition to veterancy can be psychologically challenging, and although the military provides support, the importance of social connectedness for well‐being is largely unrecognised. The significance of this oversight is highlighted by the Social Identity Model of Identity Change (SIMIC), which conceptualises life change as social identity change. SIMIC has been applied to numerous life transitions, but not to veterancy, although there is evidence that the social and psychological challenges of this transition may be especially profound (e.g., due to the chronically salient, highly structured and largely unique nature of military life and identity). To remedy this, in Study 1 (N = 210), UK‐based veterans completed an online survey. Consistent with SIMIC, social group maintenance and gain predicted mental health via the psychological resources they provided (meaning, self‐esteem, sense of personal control), and group gain was predicted by perceived military support during the transition. Study 2 (N = 14) extended these findings qualitatively through exploration of veterans' transition experiences. These studies are the first to apply aspects of the SIMIC to the veterancy transition, and they show the applicability of SIMIC in this context. They also highlight the need for transition‐related education that includes guidance on group joining and reconnecting.

Published: November 2023

AbstractTelluronium salts [Ar2MeTe]X were synthesized, and their Lewis acidic properties towards a number of Lewis bases were addressed in solution by physical and theoretical means. Structural X‐ray diffraction analysis of 21 different salts revealed the electrophilicity of the Te centers in their interactions with anions. Telluroniums’ propensity to form Lewis pairs was investigated with OPPh3. Diffusion‐ordered NMR spectroscopy suggested that telluroniums can bind up to three OPPh3 molecules. Isotherm titration calorimetry showed that the related heats of association in 1,2‐dichloroethane depend on the electronic properties of the substituents of the aryl moiety and on the nature of the counterion. The enthalpies of first association of OPPh3 span −0.5 to −5 kcal mol−1. Study of the affinity of telluroniums for OPPh3 by state‐of‐the‐art DFT and ab‐initio methods revealed the dominant Coulombic and dispersion interactions as well as an entropic effect favoring association in solution. Intermolecular orbital interactions between [Ar2MeTe]+ cations and OPPh3 are deemed insufficient on their own to ensure the cohesion of [Ar2MeTe ⋅ Bn]+ complexes in solution (B=Lewis base). Comparison of Grimme's and Tkatchenko's DFT‐D4/MBD‐vdW thermodynamics of formation of higher [Ar2MeTe ⋅ Bn]+ complexes revealed significant molecular size‐dependent divergence of the two methodologies, with MBD yielding better agreement with experiment.

Published: November 2023

AbstractLiquid crystals (LCs) are well known for inherent responsiveness to external stimuli, such as light, thermal, magnetic, and electric fields. Cholesteric LCs are among the most fascinating, since they possess distinctive optical properties due to the helical molecular orientation. However, the good flow, easy contamination, and poor stability of small‐molecule LCs limit their further applications, and microencapsulation as one of the most effective tools can evade these disadvantages. Microencapsulation can offer shell‐core structure with LCs in the core can strengthen their stability, avoiding interference with the environment while maintaining the stimuli‐responsiveness and optical properties. Here, we report recent progress in the fabrication and applications of cholesteric LC microcapsules (CLCMCs). We summarize general properties and basic principles, fabrication methods including interfacial polymerization, in‐situ polymerization, complex coacervation, solvent evaporation, microfluidic and polymerization of reactive mesogens, and then give a comprehensive overview of their applications in various popular domains, including smart fabrics, smart sensor, smart displays, anti‐counterfeiting, information encryption, biomedicine and actuators. Finally, we discuss the currently facing challenges and the potential development directions in this field.
Insight into the Role of Isolated Gold Atoms‐Ceria Conjunction in Catalyzing the Water‐Gas Shift Reaction†
Authors: Fu Xin‐Pu , Hui‐Zhao  , Wang Wei‐Wei , Jia Chun‐Jiang 
Published: November 2023

Comprehensive SummaryAs the promising catalysts for the water‐gas shift (WGS) reaction, the activity of Au‐CeO2 composites is susceptible to the aggregation size and electronic state of Au species. Previous reports were extensively focused on the discrepancy between nonmetallic Au and metallic Au nanoparticles, whereas the understanding of the authentic role of the isolated Au atoms was limited. Herein, we investigated the catalytic behavior and structural information over two types of Au/CeO2 catalysts, in which the predominant conjunctions were isolated Au1‐CeO2 and Aun‐CeO2, respectively. Based on comprehensive characterizations, particularly by in‐situ Raman and in‐situ DRIFTS, we found that the isolated Au atoms were responsible for enhancing the reducibility of the CeO2 matrix. The CO adsorption ability on the isolated Au sites was significantly inferior to clustered Au atoms, especially at relatively high temperatures (> 200 °C). As a result, the boosted O vacancy on the isolated Au1‐CeO2 conjunctions could improve the H2O activation ability for the Au‐CeO2 catalysts and demonstrate a comparable activity to the clustered Aun‐CeO2 sites. This work might deepen understanding of the catalytic function for the isolated Au1 site within Au/CeO2 systems while catalyzing the WGS reaction.

Published: November 2023

AbstractThe use of standardized reporting systems for non‐gynecologic cytopathology has made enormous gains in popularity during the past decade, including for thyroid fine‐needle aspiration, urine cytology, serous effusions, pancreas, lymph nodes, lung, and more. In February 2018, the first edition Atlas of the Milan System for Reporting Salivary Gland Cytopathology (MSRSGC) was published. The MSRSGC defines six diagnostic fine‐needle aspiration categories encompassing the spectrum of non‐neoplastic, benign, and malignant lesions of the salivary glands. The goal of the MSRSGC is to combine each diagnostic category with a defined risk of malignancy and a specific clinical and/or surgical management algorithm. Since its initial publication in 2018, more than 200 studies and commentaries have been published confirming the role of the MSRSGC. The second edition of the MSRSGC, published in July 2023, includes refined risks of malignancy based on systematic reviews and meta‐analyses, a new chapter summarizing the use of salivary gland imaging, new advances in ancillary testing, and updates in nomenclature.

Published: November 2023

AbstractEpalrestat is a reversible noncompetitive inhibitor of aldose reductase with selective inhibition of aldose reductase. It can inhibit the accumulation of sorbitol in red blood cells in patients with diabetic peripheral neuropathy and can improve patients’ conscious symptoms and neurological dysfunction. This study was designed to evaluate the bioequivalence in healthy Chinese subjects of a new test formulation and reference formulation of oral epalrestat (50 mg) in the fasting state. The study was performed with 44 healthy Chinese subjects according to a randomized 2‐way crossover design. The main pharmacokinetic parameters of test formulation and reference formulation as follows: 4793 and 4781 ng/mL for maximum plasma concentration, 8556 and 8431 ng h/mL for area under the plasma concentration‐time curve extrapolated to infinity. The test formulation of epalrestat was bioequivalent to the reference formulation. The bioequivalence study of epalrestat in healthy Chinese subjects suggests that the test and reference formulations have similar pharmacokinetics and both formulations are well tolerated in the dose range studied in healthy Chinese subjects. All these findings provided valuable pharmacokinetic knowledge for further clinical development.

Published: November 2023

AbstractPoa pratensis is a widely cultivated turf grass with strong cold and drought resistance. While the chloroplast genome of P. pratensis has been sequenced, its mitochondrial genome remains unexplored. This study assembled the mitochondrial genome of P. pratensis, revealing a total length of 447,463 bp and a guanine‐cytosine content of 44.41%. Its main structure comprises a single circular molecule. Annotation results revealed the presence of 56 genes, including 34 unique protein‐coding genes, 19 tRNA genes, and three rRNA genes. Additionally, we investigated codon usage bias, repeats, sequence migration, and RNA editing events in the genome. Furthermore, we constructed a phylogenetic tree based on the mitochondrial genomes of P. pratensis and 20 related plants. Notably, synteny analysis results demonstrated that the mitochondrial genome of P. pratensis exhibited greater variation and more significant rearrangement than those of its close relatives. This study reports the complete mitochondrial genome of P. pratensis for the first time, providing a solid foundation for further research into the genetics of bluegrass.

Published: November 2023

AbstractMicroclimate and vegetation structure control evapotranspiration (ET) from land surfaces at stand and landscape scales. Tropical rainforests are among the most diverse and complex terrestrial ecosystems, harbouring vast plant and animal species throughout their dense multistory canopy. They contribute substantially to global precipitation through their high ET. However, there is little information about ET influences at very small spatial scales under given climatic conditions. In a tropical rainforest on Sumatra, we studied the relationship between pixel‐level ET as derived from high‐resolution (~10 cm), near‐surface thermography from an unmanned aerial vehicle (UAV) and canopy structure as derived from red–green–blue (RGB) image and three‐dimensional (3D) point cloud analyses. The 16 derived potential predictors encompassed vegetation height, height variability, vegetation density and reflectance variables. Using regression models, several of the studied variables had a significant linear relationship with ET, but the explained variance was only marginal. However, applying a random forest algorithm including forward feature selection and target oriented cross validation explained substantial parts of the pixel‐level variance in ET (R2 = 0.56–0.65), thus indicating multiple non‐linear relationships with interactions among predictor variables. Therein, green leaf index, leaf area density and vegetation height were often the most important variables for the prediction outcome, but their sequence varied among the four study plots. Overall, combining canopy structure variables derived from RGB photogrammetry explained relatively large parts of spatial ET variations. Our study thus indicates the large potential of combining UAV‐based thermography and photogrammetry techniques with machine learning approaches to better understand ET but also suggests that more work remains to be done in explaining ET patterns at very small spatial scales.

Authors: Deepak Thirumalai , Bharat Bansod Sneha , R. Babu Anju 
Published: November 2023

AbstractThe decellularized pericardium has been widely used in cardiac tissue engineering, whereas its clinical applications are limited due to weak mechanical performance, high collagen exposure, and being prone to microbial contamination. In this study, a biohybrid scaffold of the decellularized caprine pericardium (DCP) and graphene oxide (GO) was fabricated by an immersion coating technique. The antimicrobial activity of GO was evaluated against Escherichia coli and showed minimum inhibitory concentration at 125 μg/mL and minimum bactericidal concentration at 250 μg/mL. The presence of GO on the surface of the biohybrid GO‐DCP was confirmed through SEM analysis. The existence of glycosaminoglycan, elastin, and collagen in the DCP and GO‐DCP was inferred from the FTIR spectra. The biocompatibility of GO‐DCP was studied by seeding valvular interstitial cells, and the results show GO coating supports cell adhesion on the serous and fibrous sides of the DCP. Further, the biomechanical response of DCP is unaltered by the presence of GO. In conclusion, GO enhances the biological performance of decellularized pericardium, which can be used in cardiac tissue engineering applications.
