Green synthesis of reduced graphene oxide anchored Fe3O4‐Pd hetero‐nanostructure: An efficient, magnetically separable and reusable catalyst for Beckmann rearrangement of aldoximes to amides
Authors: Hazarika Shikharani , Borah Geetika 
Published: October 2023

The multifaceted Fe3O4‐Pd@rGO nanocomposite (NC) has been synthesized successfully by a biogenic method using Ocimum tenuiflorum leaf extract. The preparation of graphene oxide (GO) was done by the well‐known modified Hummer method. The as‐synthesized Fe3O4‐Pd@rGO NC was extensively characterized by various analytical techniques, namely, Fourier transform infrared (FTIR), X‐ray diffraction (XRD), field emission scanning electron microscopy‐energy‐dispersive X‐ray spectroscopy (FESEM‐EDX), high‐resolution transmission electron microscopy (HRTEM), inductively coupled plasma‐atomic emission spectrometry (ICP‐AES), X‐ray photoelectron spectroscopy (XPS), thermogravimetric analysis (TGA), vibrating sample magnetometry (VSM) and Brunauer–Emmett–Teller (BET) surface area analysis. The absence of peak corresponding to υ(CO) at 1732 cm−1 in the FTIR spectrum of Fe3O4‐Pd@rGO enumerates the reduction of GO to reduced graphene oxide (rGO) during Fe3O4‐Pd nanoparticle (NP) synthesis with O. tenuiflorum leaf extract. The XRD pattern reveals the existence of rGO, cubic‐phased spinel‐structured Fe3O4 along with the formation of metallic Pd NP without any impurities. The FESEM image designates the spherical and flake‐like morphology of the NC. The crystallite size of the NC was calculated employing the Debye–Scherrer equation and was found to be 3.45 nm corresponding to the (220) plane. The average particle size of Fe3O4‐Pd NPs as estimated from the particle size distribution curve was ascertained as 3.03 nm. The utmost saturation magnetization value of the NC as evaluated by VSM study has appeared at 0.6219 emu g−1 having coercivity value of 335.1 Oe and remanent magnetization value of 0.0767 emu g−1, suggesting the existence of a ferromagnetic material in the synthesized NC. It was a stable and highly efficient catalyst for Beckmann rearrangement of aldoximes using in an environment‐friendly medium. It afforded up to 99% isolated yield of the preferred products under acid‐free condition, avoiding the use of any harsh chemicals that will be beneficial for future industrial applications. Finally, the magnetic component of the NC allowed for easy recovery of the catalyst, thereby eliminating the chance of leaching of metal atoms, and was reusable till six successive cycles without apparent loss of its catalytic performance.

AbstractBiological treatment is gaining ground as a means to enhance removal of total organic carbon (TOC) as part of a multi‐barrier treatment train for water reuse. Here we applied biodegradable dissolved organic carbon (BDOC) analysis to evaluate the extent of removal of various TOC fractions through a pilot‐scale water reuse train employing flocculation/sedimentation, ozone, biologically active carbon (BAC), and granular activated carbon (GAC). BDOC analysis highlighted GAC and ozone treatments as critical to non‐biodegradable dissolved organic carbon removal and the need to optimize BAC performance to maximize GAC adsorption capacity. BDOC analysis was further applied to benchmark process performance to operational conditions, such as empty bed contact time (EBCT), occurrence of nitrification, and operational upsets. The lower EBCT proved to be less resilient to nonideal conditions. Overall, BDOC analysis proved an asset for understanding and improving operation of ozone/BAC/GAC treatments for water reuse.
Caresses, whispers and affective faces: A theoretical framework for a multimodal interoceptive mechanism underlying ASMR and affective touch
Authors: Villena‐Gonzalez Mario 
Published: October 2023

AbstractAutonomous sensory meridian response (ASMR) and affective touch (AT) are two phenomena that have been independently investigated from separate lines of research. In this article, I provide a unified theoretical framework for understanding and studying them as complementary processes. I highlight their shared biological basis and positive effects on emotional and psychophysiological regulation. Drawing from evolutionary and developmental theories, I propose that ASMR results from the development of biological mechanisms associated with early affiliative behaviour and self‐regulation, similar to AT. I also propose a multimodal interoceptive mechanism underlying both phenomena, suggesting that different sensory systems could specifically respond to affective stimulation (caresses, whispers and affective faces), where the integration of those inputs occurs in the brain's interoceptive hubs, allowing physiological regulation. The implications of this proposal are discussed with a view to future research that jointly examines ASMR and AT, and their potential impact on improving emotional well‐being and mental health.
Mitochondrial ascorbic acid prevents mitochondrial O2.− formation, an event critical for U937 cell apoptosis induced by arsenite through both autophagic‐dependent and independent mechanisms
Authors: Guidarelli Andrea , Carloni Silvia , Balduini Walter , Fiorani Mara , Cantoni Orazio 
Published: October 2023

AbstractA 16 h exposure of U937 cells to 2.5 µM arsenite promotes superoxide (
) formation and inhibition of the activity of aconitase, a
sensitive enzyme. Both responses were abolished by the complex I inhibitor rotenone, or by the respiration‐deficient phenotype. Interestingly, a similar suppressive effect was mediated by a short term pre‐exposure to a low concentration of l‐ascorbic acid (AA), previously shown to be actively taken up by the cells and by their mitochondria. The mitochondrial origin of
was confirmed by fluorescence microscopy studies, whereas different approaches failed to detect a contribution of NADPH oxidase. Under similar conditions, arsenite induced autophagy as well as a decline in mitochondrial membrane potential resulting in delayed (48 h) apoptosis. Importantly, all these events turned out to be sensitive to treatments associated with prevention of
formation, including AA, and were only partially blunted by inhibitors of autophagy. As a final note, the toxic effects mediated by
were entirely dependent on its conversion to H2O2. AA‐sensitive mitochondrial
formation is therefore involved in autophagy and apoptosis induced by arsenite in U937 cells, although part of the lethal response appears mediated by an autophagy‐independent mechanism. © 2016 BioFactors, 42(2):190–200, 2016
Kinetic Study on Alkaline Hydrolysis of Y‐substituted Phenyl Picolinates: Effects of Modification of Nonleaving Group from Benzoyl to Picolinyl on Reactivity and Reaction Mechanism
Authors: Kim Myung‐Joo , Kim Min‐Young , Um Ik‐Hwan 
Published: October 2023

Second‐order rate constants (k
OH–) for alkaline hydrolysis of Y‐substituted phenyl picolinates (6a–6i) have been measured spectrophotometrically. A linear Brønsted‐type plot is obtained with βlg = −0.34, which is typical for reactions reported previously to proceed through a stepwise mechanism with formation of an addition intermediate being the rate‐determining step (RDS). However, constants result in a much poorer Hammett correlation than constants. Furthermore, the Yukawa‐Tsuno plot exhibits an excellent linear correlation with ρ
Y
= 0.82 and r = 0.72, indicating that a negative charge develops partially on the O atom of the leaving group in the RDS. Thus, the reactions have been concluded to proceed through a forced concerted mechanism with a highly unstable intermediate 7. Comparison of the current kinetic data with those reported previously for the corresponding reactions of Y‐substituted phenyl benzoates has revealed that modification of the nonleaving group from benzoyl to picolinyl causes not only an increase in reactivity but also a change in the reaction mechanism (i.e., from a stepwise mechanism to a forced concerted pathway).
Collaboration in the Spotlight: The Open Symphony Case
Authors: Hayes Kate 
Published: October 2023

EDITOR'S SUMMARYThe voice of the performing arts is an important – though seldom heard – disciplinary component of information science research. The Open Symphony, a collaboration between a performing musician and computer science students, allowed for creative audience interaction with live music performances. But such interdisciplinary collaboration is difficult and needs to be put within the larger context of questions surrounding value, individual contribution in artistic expression and ownership in the performing arts. Indeed, tensions around the economics of art and commercial versus academic value may hinder collaborations between artists and academia, but with the right framework and definitions of value these efforts could lead to additional forms of cross‐disciplinary exploration.

EDITOR'S SUMMARYASIS&T has continuously worked to enhance diversity and inclusion over its long history, including the formation of the Special Interest Group/International Information Issues and the name change from the American Society for Information Science and Technology to the Association for Information Science and Technology. During the 2016 ASIS&T Annual Meeting (AM), a Diversity and Inclusion Luncheon was held to promote discussion and ideas of new ways for ASIS&T to promote diversity. Attendees of the luncheon were asked to share positive personal experiences with diversity, as well as share ideas for how to bolster diversity and inclusion in future AMs and for ASIS&T as an organization. Suggestions include the meeting being held outside of North America more frequently, inclusion of mentor programs for papers and new attendees of AMs, removing North American‐centric language from communications and more ASIS&T board members from other continents. The suggestions were recommended to the ASIS&T Board for further discussion.

AbstractA novel buckybowl catcher with an extended π‐surface has been synthesized via cross‐coupling of two bowl shaped bromoindacenopicene moieties with a tolyl linker. The obtained catcher has been unambiguously characterized by 2D‐NMR and mass spectrometry. DFT calculations indicate that the curved shape of the receptor moieties is favourable for binding fullerenes. Effective binding was confirmed for interactions with C60 and C70 utilizing NMR spectroscopy and isothermal titration calorimetry (ITC). The resulting binding values show a higher affinity of the catcher towards C70 over C60. The designed catcher demonstrated the fundamental possibility of creating sensors for spherical aromaticity.

Published: October 2023

AbstractMayotte Island, a French department located in the Mozambique Channel, has for several years been faced with the consumption of “La Chimique” (LC), reputed (but extremely poorly documented) to be a mixture of tobacco and synthetic cannabinoid receptor agonists (SCRAs). One of the objectives of the CHASSE‐MAREE protocol is to assess the composition and heterogeneity of LC products through successive LC sample collection campaigns among users. Currently underway, we present here the first analytical results (samples collected in 2022). Between September and December 2022, 80 samples were collected throughout the island over three periods: 70 in the usual form of LC (small folded papers containing a plant‐like sample, mostly tobacco), 6 powders, and 4 cigarettes. Analysis was performed using liquid chromatography with high‐resolution mass spectrometry. The detected substances (number of detections) included SCRAs (MDMB‐4en‐PINACA [35], ADB‐FUBIATA [25], MDMB‐INACA [16], ADB‐BUTINACA [15], AFUBIATA [11], 4F‐MDMD‐BICA [7], CH‐PIATA [14], 5C‐APINACA [3], BZO‐HEXOXIZID [2], and 4F‐ABINACA [1]), nicotine (68), tetrahydrocannabinol (THC), cannabinol (CBN), and cannabidiol (CBD) (2), medications (amantadine [11], cyamemazine [6], and acetaminophen [3]), and a designer benzodiazepine (bromazolam [4]). The SCRAs currently in use are varied, and the market for “cooks” (those who prepare LC) is dispersed according to where and when samples are collected. These preliminary results will be supplemented by analysis of samples collected in the first half of 2023 and by an improved description of the current panorama of consumption of LC in Mayotte (mapping, effects felt and dependence, etc.).
A Control System Based on an Improved Model Auto‐Fusion Cerebellar Perceptron and Its Application to the Consensus Problem
Authors: UCHIYAMA SHOGO , OBAYASHI MASANAO , KUREMOTO TAKASHI , KOBAYASHI KUNIKAZU , MABU SHINGO 
Published: October 2023

SUMMARYIn this paper, we propose a control system based on an improved model auto‐fusion cerebellar perceptron using feedback error learning (FEL) which imitates the human cerebellum, and apply it to the consensus problem of a multiagent system (MAS). It is important to control multiple agents because each of them has its own scale and complexity. Therefore, coordinative control of the MAS for each autonomous decision‐making instance has been taken as the focus. To control MAS, we consider use of FEL related to biological movement control. We also propose an auto‐fusion mechanism for mitigation of neuronal fluctuation. We call the proposed system the “Auto‐Fusion Cerebellar Perceptron Improved Model‐Based Control System (AFCPCS)” here. Through a computer simulation of the MAS consensus problem, we demonstrate the effectiveness of the proposed method.
The Mechanism of Lithium Zincate‐Mediated I/Zn Exchange Revisited: A Computational Microsolvation Approach in THF**
Authors: Pierret Alexandre , Lefebvre Corentin , Gros Philippe C. , Denhez Clément , Vasseur Alexandre 
Published: October 2023

AbstractLithium trialkylzincate‐mediated I/Zn exchange reaction has been revisited computationally through a microsolvation approach. A never yet investigated iodoaryl derivative bearing a potential bulky para‐directing group, namely 4‐iodobenzyl mesylate, was considered as a substrate. THF as typical solvent and Et3ZnLi have also been considered for the first time in such a reaction. Three mechanistic pathways have been calculated, including (1) a literature‐inspired pathway with full preservation of the synergic character of the reagent as well as a complementary mesylate group‐directed pathway, (2) a THF‐solvated open complex‐promoted pathway and (3) an anionic pathway. While the anionic pathway appeared to be unlikely, pathway involving a THF‐solvated open zincate complex turned out to be the most energetically favored. Equivalent thermodynamic profiles were found for both complementary pathways with preservation of the synergic character of the reagent, albeit a slight preference could be attributed to that occurring with initial chelation of Li to the mesylate group (OMs) through microsolvation approach. The I/Zn exchange was shown to proceed through a lithium‐assisted aryl shuttle‐like process. The iodoaryl substrate is first converted into ArLi intermediate which in turns reacts with the remaining diorganozinc reagent.
In situ green synthesis of hybrid lead nanoparticles encased in phytochemicals for antimicrobial applications
Authors: Moustafa N. E. 
Published: October 2023

AbstractPreviously, organic immobilization matrices were used, but this study demonstrates a novel approach by utilizing in situ‐produced phytochemicals to encase the lead nanoparticles. The process involves reducing lead acetate with ingredients from Peganum harmala leaves to create a hydride‐lead nanoparticle‐phytochemical grid. To investigate the morphology and synthesis of the lead nanoparticles, a variety of spectroscopic and microscopic methods were employed. The available information indicates that the hybrid PbNPS exhibits an average nucleation site size of 14.60, indicating the presence of nanoparticles with relatively uniform sizes ranging from 12 to 19. Furthermore, the hybrid PbNPS displayed remarkable antibacterial efficacy against Staphylococcus aureus and Escherichia coli, with inhibition zones measuring 28 and 30.0 mm, respectively, when tested at a concentration of 200 μg/mL. This finding highlights two significant aspects of this research. First, the utilization of phytochemicals as a collector for the straightforward extraction of toxic lead from an aqueous medium represents a novel and innovative approach. Second, the extracted material exhibits promising antibacterial activity, presenting potential applications in the fight against bacterial infections.

AbstractLow‐grade epilepsy‐associated tumors (LEATs) are a common cause of drug‐resistant epilepsy in children. Herein, we demonstrate the feasibility of using tumor tissue derived from stereoelectroencephalography (sEEG) electrodes upon removal to molecularly characterize tumors and aid in diagnosis. An 18‐year‐old male with focal epilepsy and MRI suggestive of a dysembryoplastic neuroepithelial tumor (DNET) in the left posterior temporal lobe underwent implantation of seven peri‐tumoral sEEG electrodes for peri‐operative language mapping and demarcation of the peri‐tumoral ictal zone prior to DNET resection. Using electrodes that passed through tumor tissue, we show successful isolation of tumor DNA and subsequent analysis using standard methods for tumor classification by DNA, including Glioseq targeted sequencing and DNA methylation array analysis. This study provides preliminary evidence for the feasibility of molecular diagnosis of LEATs or other lesions using a minimally invasive method with microscopic tissue volumes. The implications of sEEG electrodes in tumor characterization are broad but would aid in diagnosis and subsequent targeted therapeutic strategies.

AbstractBackground and AimsThe 2022‐mpox outbreak has spread worldwide in a short time. Integrated knowledge of the epidemiology, clinical characteristics, and transmission of mpox are limited. This systematic review of peer‐reviewed articles and gray literature was conducted to shed light on the epidemiology, clinical features, and transmission of 2022‐mpox outbreak.MethodsWe identified 45 peer‐reviewed manuscripts for data analysis. The standards of the Preferred Reporting Items for Systematic Review and Meta‐Analysis (PRISMA) Statement and Cochrane Collaboration were followed for conducting the study.ResultsThe case number of mpox has increased about 100 times worldwide. About 99% of the cases in 2022 outbreak was from non‐endemic regions. Men (70%–98% cases) were mostly infected with homosexual and bisexual behavior (30%–60%). The ages of the infected people ranged between 30 and 40 years. The presence of HIV and sexually transmitted infections among 30%–60% of cases were reported. Human‐to‐human transmission via direct contact and different body fluids were involved in the majority of the cases (90%–100%). Lesions in genitals, perianal, and anogenital areas were more prevalent. Unusually, pharyngitis (15%–40%) and proctitis (20%–40%) were more common during 2022 outbreak than pre‐2022 outbreaks. Brincidofovir is approved for the treatment of smallpox by FDA (USA). Two vaccines, including JYNNEOSTM and ACAM2000®, are approved and used for pre‐ and post‐prophylaxis in cases. About 100% of the cases in non‐endemic regions were associated with isolates of IIb clade with a divergence of 0.0018–0.0035. Isolates from B.1 lineage were the most predominant followed by B.1.2 and B.1.10.ConclusionThis study will add integrated knowledge of the epidemiology, clinical features, and transmission of mpox.
