Authors: Sukumar Thenmozhi , Kadirvelu Krishna 
Published: October 2022

AbstractA novel composite core‐shell nanofibers of poly(vinyl acetate) (PVAc) as core incorporated with magnesium oxide nanoparticles (MgO NPs) and cellulose acetate (CA) as shell were prepared using co‐axial electrospinning technique. Core‐shell morphology of the prepared composite nanofibers was confirmed by scanning electron microscope (SEM) and field emission‐SEM (FE‐SEM) imaging techniques and presence of metal oxide in core‐shell nanofibers was confirmed from the energy dispersive X‐ray (EDX) analysis. Further, thermal, chemical and mechanical properties of the prepared materials were studied with Fourier transform‐infrared spectroscopy (FTIR), powder X‐ray diffraction (XRD), tensile measurements, thermogravimetry analysis (TGA) and differential scanning calorimetry (DSC) analysis. Finally, fire retardant properties of the prepared nanofibers were studied by inclined flammability and limited oxygen index (LOI) testing. Higher mechanical strength and enhanced fire resistance was reported from the above thorough analysis and therefore, the prepared material could fit well in fire resistance applications.

Published: October 2022

AbstractRecently, micro/mesoporous biomass‐based functional carbon as an excellent electrode material and energy storage device has attracted massive attention due to the availability of abundant raw materials, adaptability to pore structure, good chemical‐physical behaviors, high conductivity, enhanced energy density, and long life cyclic stability. This study performs micro/meso carbon from the novel galangal leaves biomass through KOH and CO2 activation as electrodes material for symmetric supercapacitors. The activated carbon obtained showed a clear hierarchical pore structure with an excellent micro:meso ratio of 56.72 %:43.28 % which caused their high electrochemical properties. The carbon was further assembled into electrodes through a binder‐free solid disc designed to assess the electrochemical performance as a supercapacitor. The results indicated that the galangal leaves‐based adapted micro/mesoporous carbon obtained a high specific capacitance of 161 F g−1 at 1 A g−1. Additionally, the symmetric supercapacitor had a specific capacitance retention rate of 78 % at 10 mV s−1 and low resistance in the aqueous electrolyte of 1 M H2SO4. The maximum energy density was 19.53 Wh kg−1 at an optimum power density of 132.32 W kg−1. Therefore, the appropriate micro/mesopores carbon ratio based on the novel galangal leaves biomass can be considered as a good electrode material for high‐performance supercapacitor.

Published: October 2022

AbstractGlycals have been extensively utilized as a versatile building block in the constructions of C‐glycosides, branched sugars, and the total synthesis of natural products and biologically potent molecules. The versatility of glycals can be attributed to their easy availability and the presence of endocyclic ring oxygen in conjugation with the double bond. The inbuilt chirality further enhances its applicability in the chiral pool synthesis of natural products and pharmaceuticals. In this review, we have summarized the development made in the total synthesis of natural products and some medicinally relevant molecules from glycals.

Published: October 2022

AbstractAn electrochemical sensor‐based on nickel selenide quantum dot, capped with 3‐mercaptopropionic acid (3‐MPA), was embedded on an L‐cysteine modified gold electrode for nevirapine (NVP) detection. The 3‐MPA‐NiSe2QD material was fully characterised using FTIR, SEM, Raman, HR‐TEM, XRD, SAXS, PL and UV‐Vis. Differential pulse voltammetry was used to study the electrochemical responses of 3‐MPA‐NiSe2QD/L‐cyst/Au electrochemical sensor to NVP, with a characteristic oxidation peak at 0.76 V. The electrochemical sensor obtained a low limit of detection (LOD) value of 0.0133 pM (0.0035 ng/L), limit of quantification (LOQ) of 0.0442 pM (0.0118 ng/L) and sensitivity of 6.15 μA/pM with a linear range of 0.25–0.63 pM, respectively. Thus, the reproducibility, stability, and repetitive usability shown by the proposed sensor made it suitable for the determination of nevirapine in real wastewater samples.

Published: October 2022

AbstractThere are quite a substantial number of impurities reported related to Ibuprofen and Sunitinib. Many published methods are also available for the separation of Ibuprofen and its impurities. However, the isolation of these related compounds in handful quantity by separation technique is a tedious, time consuming and cost intensive process. Similarly, to our knowledge, there is no synthetic method available for the amide impurity of Sunitinib. In order to prove the absence or presence of these impurities within the permissible limit, according to different pharmacopoeias, it is pertinent to synthesize each of them.
Assembly of Mg‐Mo‐Al‐Layered double hydroxides (LDHs) @ MoO42− and Its Synergistic Photocatalytic Degradation of Phenol in Wastewater

Published: October 2022

AbstractMg2+‐Mo6+‐Al3+‐MoO42−‐Layered double hydroxides (LDHs) materials were successfully prepared via a hydrothermal method by doping Mo6+ in hydroxide laminates and inserting MoO42− to replace the interlayer anions of LDHs materials. The samples were characterized by X‐ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscope (TEM), Fourier transform infrared spectrometer (FTIRS) and ultraviolet‐visible spectrophotometer (UV). The electronic density of states was calculated using the density functional theory (DFT) of Vienna Ab‐initio Simulation Package (VASP). The effects of Mo6+ and MoO42− on the structure, morphology, electronic structure and photocatalytic performance of Mg2+‐Al3+‐LDHs were systematically studied. The conditions for phenol degradation by Mg2+‐Mo6+‐Al3+‐MoO42−‐LDHs were optimized by single factor analysis and response surface methodology. The results show that the MoO42− anion reduces the band gap width and thus enhances the absorption of low‐energy photons. The interaction between cations and anions enhances the photocatalytic performance. When the dosage of Mg2+‐Mo6+‐Al3+‐MoO42−‐LDHs was 0.03 g, the temperature was 40 °C and the visible light irradiation was 15 min, the removal rate of phenol reached 94.76 %.

AbstractIn general, organic strong bases and precious metal complexes serve as catalysts in the dehydrogenative coupling reaction of silanes with alcohols. However, these catalysts can't be easily separated from the catalytic system. Moreover, the self‐polymerization of silanes usually occurs in the presence of strong bases. In this work, utilizing the coordination of imidazolium nitrogen with Pd metal nanoparticles, the alkaline imidazole‐functionalized porous organic polymer stabilized palladium nanoparticles (Pd/PDVB‐Vim) is developed to compensate for the above‐mentioned drawbacks. The Pd/PDVB‐Vim catalyst is characterized and applied in the dehydrogenative coupling reaction of silanes with alcohols under mild conditions (30 °C). The characterization results demonstrate the Pd NPs are uniformly dispersed on PDVB‐Vim with ultrasmall particle size (Ca. 2.00 nm) and the strong interaction of the nitrogen on PDVB‐Vim and Pd NPs is obvious in Pd/PDVB‐Vim. This strong interaction makes the Pd/PDVB‐Vim catalyst exhibits the best stability and reusability.

Published: October 2022

AbstractOver the last decade, artificial enzymes (nanozymes) have undergone substantial development in the field of sensing. In this study, Au−Ag bimetallic nanoparticles (NPs) decorated on reduced graphene oxide sheets (AuAg‐rGO) nanocomposite has been developed as a novel colorimetric probe based on the peroxidase imitating activity of the nanozyme. AuAg‐rGO nanocomposite proved to feature an intrinsic peroxidase mimic activity, facilitating the oxidation of a peroxidase substrate like 3,3’,5,5’‐tetramethylbenzidine (TMB) with high efficiency to oxidised TMB (blue coloured product) with the aid of hydrogen peroxide (H2O2). The characteristic Michaelis‐Menten kinetics study allowed the establishment of the catalytic performance of AuAg‐rGO as an artificial enzyme. Glutathione (GSH) displays inhibiting effect on the oxidation of the peroxidase substrate, TMB. Therefore, AuAg‐rGO nanozyme was applied for detection of GSH and exhibited exceptional selectivity and sensitivity with a low limit of detection (LOD) of 38 nM within the 0–200 μM concentration range. The artificial nanozyme system reported here is simple, convenient, and straightforward for colorimetric sensing of GSH.

AbstractTaking patients' medical history correctly is the basis of diagnosis and therapy. Medical students as a vulnerable group may perceive patient–physician interactions as stressful. This study examines stress among medical students in different degrees of fidelity when taking a patient's medical history. In this longitudinal study, students' stress levels were assessed during scenarios with different degrees of fidelity (role‐play, simulated patient encounters and real patient encounters) using standardised questionnaires (State‐Trait Anxiety Inventory and a distress scale) and the physiological measurement of heart rate variability. The stress level of participating medical students (N = 128) was expected to significantly increase during scenarios of increasing fidelity (Mroleplay = 2.08 ± 0.92; SPEs: Msimulatedpatient = 2.68 ± 1.08; RPEs: Mrealpatient = 3.35 ± 1.08; p < 0.001). Whereas physiological stress was significantly higher with real patients (N = 106), psychological stress was not affected by the fidelity of the scenarios (N = 85). Medical students experienced stress when taking patients' medical history. Medical students might be unaware of their perceived stress based on the results. Thus, they should know how to cope with stress in such situations.

AbstractThe design and development of advanced energy storage devices with good energy/power densities and remarkable cycle life has long been a research hotspot. Metal‐ion hybrid capacitors (MHCs) are considered as emerging and highly prospective candidates deriving from the integrated merits of metal‐ion batteries with high energy density and supercapacitors with excellent power output and cycling stability. The realization of high‐performance MHCs needs to conquer the inevitable imbalance in reaction kinetics between anode and cathode with different energy storage mechanisms. Featured by large specific surface area, short ion diffusion distance, ameliorated in‐plane charge transport kinetics, and tunable surface and/or interlayer structures, 2D nanomaterials provide a promising platform for manufacturing battery‐type electrodes with improved rate capability and capacitor‐type electrodes with high capacity. In this article, the fundamental science of 2D nanomaterials and MHCs is first presented in detail, and then the performance optimization strategies from electrodes and electrolytes of MHCs are summarized. Next, the most recent progress in the application of 2D nanomaterials in monovalent and multivalent MHCs is dealt with. Furthermore, the energy storage mechanism of 2D electrode materials is deeply explored by advanced characterization techniques. Finally, the opportunities and challenges of 2D nanomaterials‐based MHCs are prospected.
Unlocking the Potential of Vanadium Oxide for Ultrafast and Stable Zn2+ Storage Through Optimized Stress Distribution: From Engineering Simulation to Elaborate Structure Design

Published: October 2022

AbstractCompared with lithium‐ion batteries (LIBs), aqueous zinc batteries (AZIBs) have received extensive attention due to their safety and cost advantages in recent years. The cathode determines the electrochemical performance of AZIBs to a large extent. Vanadium‐based materials exhibit excellent capacity when used as AZIB cathodes. However, unexpected structural stress is inevitably induced during cycling and high current densities, which can gradually lead to structural deterioration and capacity decay. In fact, the stress/strain distribution in nanomaterials is crucial for electrochemical performance. In this work, the optimized stress distribution of the hierarchical hollow structure is verified by the finite element simulation of COMSOL software firstly. Guided by this model, a simple solvothermal method to synthesize hierarchical hollow vanadium oxide nanospheres (VO‐NSs), consisting of ≈10 nm ultrathin nanosheets and ≈500 nm hollow inner cavities, is employed. And a highly disordered structure is introduced to the VO‐NSs by in situ electrochemical oxidation, which can also weaken the structural stress during Zn2+ insertion and extraction. Benefiting from this unique structure, VO‐NSs exhibit high‐rate and stable Zn2+ storage capability. The strategy of engineering‐driven material design provides new insights into the development of AZIB cathodes.

Published: October 2022

AbstractZearalenone (ZEA), a common mycotoxin in animal feed, is harmful to public health and causes huge economic losses. The potential target proteins of ZEA and its derivatives were screened using the PharmMapper database and the related genes (proteins) of the testis were obtained from Genecards. We obtained 144 potential targets of ZEA and its derivatives related to the testis using Venn diagrams. The PPI analysis showed that ZEA had the most targets in testis, followed by ZAN, α‐ZAL, β‐ZEL, α‐ZEL, and β‐ZAL. Kyoto Encyclopedia of Genes and Genomes (KEGG) and Gene Ontology (GO) analyses evaluated the metabolic and cancer pathways. We further screened four hub genes: RAC3, CCND1, EP300, and CTNNB1. Eight key biological processes were obtained by GO analysis, and four important pathways were identified by KEGG analysis. Animal and cell experimental results confirmed that ZEA could inhibit the expression of four key KEGG pathway protein components and four hub proteins that interfere with cell adhesion by inhibiting the focal adhesion structure of the testis, Leydig cells, and Sertoli cells. Collectively, our findings reveal that the destruction of the focal adhesion structure in the testis is the mechanism through which ZEA damages the male reproductive system.

Published: October 2022

AbstractAdaptation constraints within crop species have resulted in limited genetic diversity in some breeding programs and areas where new crops have been introduced, for example, for lentil (Lens culinaris Medik.) in North America. An improved understanding of the underlying genetics involved in phenology‐related traits is valuable knowledge to aid breeders in overcoming limitations associated with unadapted germplasm and expanding their genetic diversity by introducing new, exotic material. We used a large, 18 site‐year, multienvironment dataset phenotyped for phenology‐related traits across nine locations and over 3 yr along with accompanying latent variable phenotypes derived from a photothermal model and principal component analysis (PCA) of days from sowing to flower (DTF) data for a lentil diversity panel (324 accessions), which has also been genotyped with an exome capture array. Genome‐wide association studies (GWAS) on DTF across multiple environments helped confirm associations with known flowering‐time genes and identify new quantitative trait loci (QTL), which may contain previously unknown flowering time genes. Additionally, the use of latent variable phenotypes, which can incorporate environmental data such as temperature and photoperiod as both GWAS traits and as covariates, strengthened associations, revealed additional hidden associations, and alluded to potential roles of the associated QTL. Our approach can be replicated with other crop species, and the results from our GWAS serve as a resource for further exploration into the complex nature of phenology‐related traits across the major growing environments for cultivated lentil.
Introduction: Towards Responsible Plant Data Linkage
Authors: Leonelli Sabina , Williamson Hugh F. 
Published: October 2022

AbstractThis chapter provides a framing for this volume by reviewing the significance and the organisational, technical and social opportunities and challenges related to plant data linkage. We review what “responsible practice” means in relation to the plant environments being documented, the infrastructures used to circulate data, the institutions involved in data governance and the communities involved in plant data work. We show how, across these domains, responsible plant data linkage involves consideration of technical, legal, ethical and conceptual dimensions, thereby: (1) creating and maintaining digital infrastructures, technical standards and discussion venues focused on critical data reuse; (2) developing adequate legal and institutional frameworks that work transnationally; (3) identifying and implementing guidelines for what constitutes acceptable data use, together with systems to monitor and allocate responsibility for breaches and mistakes; and (4) considering the variety of views on what constitutes agricultural development in the first place and how plant research can sustainably, reliably and responsibly contribute to achieving food security. The production of sustainable, responsible and reliable agricultural solutions in the face of climatic and political change depends on the flourishing of transnational, interdisciplinary collaborations such as those represented in this volume.
Digital Sequence Information and Plant Genetic Resources: Global Policy Meets Interoperability
Authors: Manzella Daniele , Marsella Marco , Jaiswal Pankaj , Arnaud Elizabeth , King Brian 
Published: October 2022

AbstractPlant genetic resources are source genetic material for conducting research and breeding. The use of this material is subject to international and national regulations on access and benefit-sharing (ABS). With modern genetic technologies generating desired trait and gene function improvement by replicating genetic signatures, ABS must adapt to the new technological reality. As the constituencies of international ABS conventions discuss if and how to extend the application of the conventions to digital sequence information (DSI) derived from source material, the genomics science community resists any incumbrance to continued free and unrestricted access to such information. Based on current ABS discussions and the likely future co-existence of diverse policy regimes, this paper proposes interoperability among data systems as an essential tool to implement legal solutions for benefit-sharing as well as advance science and innovation objectives. Two information technology tools are suggested for associating DSI to plant genetic resources and reciprocal citations with data exchange, namely digital object identifiers and digital genetic objects. This paper concludes that interoperability should be experimented with in both its technical and social dimensions, in order to support long-term alliances between policy and science through data archives, knowledge bases and live specimen collection resources.
Governing Agricultural Data: Challenges and Recommendations
Authors: Devare Medha , Arnaud Elizabeth , Antezana Erick , King Brian 
Published: October 2022

AbstractThe biomedical domain has shown that in silico analyses over vast data pools enhances the speed and scale of scientific innovation. This can hold true in agricultural research and guide similar multi-stakeholder action in service of global food security as well (Streich et al. Curr Opin Biotechnol 61:217–225. Retrieved from https://doi.org/10.1016/j.copbio.2020.01.010, 2020). However, entrenched research culture and data and standards governance issues to enable data interoperability and ease of reuse continue to be roadblocks in the agricultural research for development sector. Effective operationalization of the FAIR Data Principles towards Findable, Accessible, Interoperable, and Reusable data requires that agricultural researchers accept that their responsibilities in a digital age include the stewardship of data assets to assure long-term preservation, access and reuse. The development and adoption of common agricultural data standards are key to assuring good stewardship, but face several challenges, including limited awareness about standards compliance; lagging data science capacity; emphasis on data collection rather than reuse; and limited fund allocation for data and standards management. Community-based hurdles around the development and governance of standards and fostering their adoption also abound. This chapter discusses challenges and possible solutions to making FAIR agricultural data assets the norm rather than the exception to catalyze a much-needed revolution towards “translational agriculture”.
