La discussion à visée philosophique : un nouveau paradigme d’autorité éducative et d’éthique relationnelle
Authors: Budex Christian 
Published: March 2023

La formation des enseignants à la conduite de Discussion à Visée Philosophique avec les enfants les initie à un nouveau paradigme d’autorité éducative qui modifie et bonifie leur posture, tant sur le plan éthique qu’épistémique. Cette pratique contribue au bonheur d’enseigner et d’apprendre pour trois raisons principales : elle redonne du sens aux apprentissages en cultivant un rapport au savoir heuristique et collaboratif ; elle forge une éthique relationnelle qui tisse des relations plus confiantes entre enseignants et élèves ; elle initie les enseignants à des gestes professionnels transférables dans d’autres situations éducatives qui contribuent à l’amélioration du climat scolaire.
Le bonheur du métier. Le cas des enseignants du primaire en France
Authors: Marcel Jean-François 
Published: March 2023

Dans le contexte d’une école française en crise, l’article défend une idée force : l’exercice professionnel, aussi dégradé et cabossé soit-il, ne peut « tenir » que s’il existe entre l’enseignant et son métier un lien allant bien au-delà des contingences du travail au quotidien. C’est ce lien, qui subsiste malgré tout, que nous identifierons comme le « bonheur du métier » de l’enseignant du primaire. La problématisation mobilise les réflexions de Kant et d’Osty pour circonscrire l’objet en positionnant le bonheur du côté du métier (et pas du travail réalisé). Elle est prolongée par une théorisation du « bonheur du métier », qui s’appuie sur Freire et Jullien pour le définir comme une potentialité, une promesse inaccessible. Elle est ensuite opérationnalisée par la fréquentation des recherches sur des notions voisines dans le cas des enseignants qui se traduisent dans le choix méthodologique d’un questionnaire. Administré par les réseaux et comporte un volet quantitatif (l’appréciation de la potentialité de 45 situations concrètes au « bonheur du métier ») et un volet qualitatif (une définition ouverte et spontanée rédigée par les répondants). Les résultats de l’enquête développent les 10 composantes du « terreau du bonheur du métier » (approche quantitative) et le triptyque de la définition de ce bonheur (approche qualitative).

Published: March 2023

A variety of climate-smart agriculture technologies, practices, and services have been introduced in climate-smart villages as adaptation strategies to cope with climate risks and ensure stability and sustainability in agricultural production. Farmers who utilize climate-smart agriculture adaptation strategies have been shown to achieve higher output, yield, and return compared to those who do not. There are promising opportunities to scale out these strategies and immense potential to enhance crop yields and farm incomes while reducing greenhouse gas emissions.
Strengthening agricultural extension services and agricultural finance by linking climate finance to traditional agricultural finance could play a significant role in scaling out climate-smart agriculture practices and technologies. This would make agriculture more sustainable and climate-resilient, thereby becoming a viable source of livelihood and food security for millions of farmers in the country. Zero budget natural farming is a climate-resilient farming system that can enhance food and nutritional security while allowing farmers to improve soil fertility and yields at lower costs, risks, and irrigation requirements. This system protects the ecosystem by improving soil organic matter, water retention, and biodiversity, while reducing air and water pollution as well as greenhouse gas emissions.

Published: March 2023

SummaryIn this article, aiming at the problems of stochastic disturbance and iron losses for the position tracking of permanent magnet synchronous motors (PMSMs), a finite‐time adaptive fuzzy command filter control (CFC) method is proposed. First, the fuzzy control method is applied to dispose of the stochastic nonlinear function in the motor model. Second, the problem of “explosion of complexity” in backstepping control is solved by using CFC technology, and the compensation signal is introduced to eliminate filtering error. Moreover, the finite‐time control method is applied to the stochastic nonlinear system of PMSMs to improve the convergence speed of the system, tracking accuracy, and anti‐interference ability. At last, the simulation results are given to verify the method can achieve fast tracking of the desired signal.

AbstractMolecular fluorophores with the second near‐infrared (NIR‐II) emission hold great potential for deep‐tissue bioimaging owing to their excellent biocompatibility and high resolution. Recently, J‐aggregates are used to construct long‐wavelength NIR‐II emitters as their optical bands show remarkable red shifts upon forming water‐dispersible nano‐aggregates. However, their wide applications in the NIR‐II fluorescence imaging are impeded by the limited varieties of J‐type backbone and serious fluorescence quenching. Herein, a bright benzo[c]thiophene (BT) J‐aggregate fluorophore (BT6) with anti‐quenching effect is reported for highly efficient NIR‐II bioimaging and phototheranostics. The BT fluorophores are manipulated to have Stokes shift over 400 nm and aggregation‐induced emission (AIE) property for conquering the self‐quenching issue of the J‐type fluorophores. Upon forming BT6 assemblies in an aqueous environment, the absorption over 800 nm and NIR‐II emission over 1000 nm are boosted for more than 41 and 26 folds, respectively. In vivo visualization of the whole‐body blood vessel and imaging‐guided phototherapy results verify that BT6 NPs are excellent agent for NIR‐II fluorescence imaging and cancer phototheranostics. This work develops a strategy to construct bright NIR‐II J‐aggregates with precisely manipulated anti‐quenching properties for highly efficient biomedical applications.

Published: March 2023

AbstractThis work demonstrates the Perylene Diimide (PDI) based multifunctional sensor for breath‐sensing and Geriatric Emergency Signalling applications fabricated by an economically viable vacuum filtration deposition technique. The deposition of PDI molecules on the flexible substrate forms a moderately conducting percolating molecular network, exhibiting superior pressure and breath‐sensing performance. The pressure sensor displays a sensitivity of 2.42198 kPa−1 with response and recovery times of ≈191 and ≈166 msec. Also, the sensor displays response and recovery times of ≈211 msec and ≈2.651 sec for breath sensing. The durability of the sensor is evaluated using a pressure‐tapping machine, and the sensor displayed a negligible performance drop over ≈10 000 cycles. The experimental findings are complemented by an ab‐initio calculation‐based comprehensive theoretical analysis of the underlying transduction mechanism for pressure and breath sensing in the context of the percolating molecular network. The theoretical analysis reveals that applied pressure and molecular adsorption significantly influence the molecular conductivity as well as the inter‐molecular quantum mechanical tunneling component, which primarily contributes to the observed increase in conductivity with pressure and exposure to breath. An Android/iOS application is developed to wirelessly receive data via Bluetooth from the sensors connected to a microcontroller.
Predicting Sulfur‐Rich Oxysulfide Perovskites for Water‐Splitting Applications Using Machine Learning
Authors: Mithal Vidur , Adhikari Surajit , Johari Priya 
Published: March 2023

AbstractSolar energy offers a promising means of addressing energy supply and storage problems, but this potential is not fully realized due to a lack of suitable semiconducting materials. The discovery of new materials with desirable properties has historically been conducted either using an experimental or a first‐principles density functional theory based study. These approaches are extremely time‐intensive, and therefore, cannot be applied effectively to study a large number of systems. In such situations, machine learning can be used to make predictions about properties of new compounds from known data, providing a more efficient route to materials discovery. Here, this approach is used to predict the bandgap of a series of oxysulfide perovskites (of the form of ABOXS3−X, X = 0,1,2,3), in general, and sulfur‐rich ABOS2, in particular. Atomic properties of constituent elements in the perovskite structures via 1.048 millions possible subsets of features are employed to train the models. Further, feature selection, kernel ridge regression, and k‐nearest neighbors classification methods are applied to downselect the promising ABOS2 based oxysulfide perovskites for water‐splitting. The accuracy of each model is determined using standard statistical metrics. Finally, seven stable but yet unsynthesized sulfur‐rich oxysulfide perovskites (BiInOS2, BiGaOS2, SbInOS2, SbGaOS2, SbAlOS2, SnZrOS2, and MgSnOS2) that show potential for water‐splitting applications are proposed.

Published: March 2023

AbstractLysosome‐targeting chimeras (LYTACs) are an emerging therapeutic modality that effectively degrade cancer cell membranes and extracellular target proteins. In this study, a nanosphere‐based LYTAC degradation system is developed. The amphiphilic peptide‐modified N‐acetylgalactosamine (GalNAc) can self‐assemble into nanospheres with a strong affinity for asialoglycoprotein receptor targets. They can degrade different membranes and extracellular proteins by linking with the relevant antibodies. CD24, a heavily glycosylated glycosylphosphatidylinositol‐anchored surface protein, interacts with Siglec‐10 to modulate the tumor immune response. The novel Nanosphere‐AntiCD24, synthesized by linking nanospheres with CD24 antibody, accurately regulates the degradation of CD24 protein and partially restores the phagocytic function of macrophages toward tumor cells by blocking the CD24/Siglec‐10 signaling pathway. When Nanosphere‐AntiCD24 is combined with glucose oxidase, an enzyme promoting the oxidative decomposition of glucose, the combination not only effectively restores the function of macrophages in vitro but also suppresses tumor growth in xenograft mouse models without detectable toxicity to normal tissues. The results indicate that GalNAc‐modified nanospheres, as a part of LYTACs, can be successfully internalized and are an effective drug‐loading platform and a modular degradation strategy for the lysosomal degradation of cell membrane and extracellular proteins, which can be broadly applied in the fields of biochemistry and tumor therapeutics.

Asymmetric Mannich/Radical Debromination Cascade of α‐Bromoketones by Dipeptide‐Phosphonium Salt Catalysis: Enantioselective Synthesis of β‐Amino Ketone‐Pyrazolinones

Published: March 2023

AbstractWe herein demonstrated an organocatalytic asymmetric Mannich/radical debromination cascade of α‐brominated ketones. With this protocol, a diversity of chiral β‐amino ketone‐pyrazolinone scaffolds, which have important versatilities in medicine and chemical synthesis, were constructed in high yields (up to 94%) with excellent enantioselectivities (up to 99% ee). This methodology features mild reaction conditions, broad substrate scope, and high functional group tolerance. Moreover, mechanistic investigations revealed that this cascade reaction proceeds through a bifunctional phosphonium salt‐catalyzed Mannich reaction of α‐brominated ketones with pyrazolinone ketimines, which is followed by an oxygen‐induced radical debromination. This protocol represents a novel activation mode for α‐brominated ketones and opens new avenues for catalytic enantioselective radical reactions under ion‐pair system.
Technical note: The use and misuse of threshold diagnostic criteria in paleopathology
Authors: Vlok Melandri 
Published: March 2023

AbstractWeighted threshold diagnostic criteria approaches have emerged for diseases that involve skeletal/bony tissue that are readily diagnosed in the field of paleopathology such as Vitamin C deficiency (scurvy), Vitamin D deficiency (rickets) and treponemal disease. These criteria differ from traditional differential diagnosis in that they involve standardized inclusion criteria based on the lesion's specificity to the disease. Here I discuss the limitations and benefits of threshold criteria. I argue that while these criteria will benefit from further revision such as inclusion of lesion severity, and the incorporation of exclusion criteria, threshold diagnostic approaches have considerable value in the future of diagnosis in the field.

Published: March 2023

AbstractUnstable cathode‐electrolyte and/or anode‐electrolyte interface in polymer‐based sodium‐ion batteries (SIBs) will deteriorate their cycle performance. Herein, a unique solvated double‐layer quasi‐solid polymer electrolyte (SDL‐QSPE) with high Na+ ion conductivity is designed to simultaneously improve stability on both cathode and anode sides. Different functional fillers are solvated with plasticizers to improve Na+ conductivity and thermal stability. The SDL‐QSPE is laminated by cathode‐ and anode‐facing polymer electrolyte to meet the independent interfacial requirements of the two electrodes. The interfacial evolution is elucidated by theoretical calculations and 3D X‐ray microtomography analysis. The Na0.67Mn2/3Ni1/3O2|SDL‐QSPE|Na batteries exhibit 80.4 mAh g−1 after 400 cycles at 1 C with the Coulombic efficiency close to 100 %, which significantly outperforms those batteries using the monolayer‐structured QSPE.

AbstractMikrowellen Drei‐Wellen Mischen ist ein bemerkenswerter, neuartiger Ansatz für tief gehende Untersuchungen an chiralen Molekülen. Diese nicht‐lineare und kohärente Technik, die auf resonanten Mikrowellenpulsen basiert, dient als robuste Methode zur Unterscheidung von Enantiomeren chiraler Moleküle und zur Bestimmung des Enantiomerenüberschusses, sogar für komplexe Mischungen chiraler Moleküle. Neben solchen analytischen Anwendungen erlaubt uns die Verwendung maßgeschneiderter Mikrowellenpulse die Kontrolle und Manipulation von Chiralität auf der Molekülebene. Der vorliegende Artikel liefert einen Überblick zu jüngsten Entwicklungen im Bereich des Mikrowellen Drei‐Wellen Mischens und seine Erweiterung zu enantiomerenspezifischem Populationstransfer. Letzteres ist ein entscheidender Schritt in Richtung Enantiomerentrennung – energetisch und schließlich auch räumlich. Im letzten Abschnitt präsentieren wir neue experimentelle Ergebnisse zur Verbesserung des enantiomerenspezifischen Populationstransfers, bei denen wir einen Enantiomerenüberschuss von 40 % in dem Rotationsenergieniveau von Interesse allein mit Hilfe von Mikrowellenpulsen erreichen konnten.

AbstractCatalytic enantioselective coupling of 1,1‐disubstituted allenes and aldehydes through regiodivergent oxidative cyclization followed by stereoselective protonation or reductive elimination promoted by chiral phosphine‐Co complexes is presented. Such processes represent unprecedented and unique reaction pathways for Co catalysis that enable catalytic enantioselective generation of metallacycles with divergent regioselectivity accurately controlled by chiral ligands, affording a wide range of allylic alcohols and homoallylic alcohols that are otherwise difficult to access without the need of pre‐formation of stoichiometric amounts of alkenyl‐ and allyl‐metal reagents in up to 92 % yield, >98 : 2 regioselectivity, >98 : 2 dr and >99.5 : 0.5 er.
Stereospecific Synthesis of Enantiopure [6]Helicene Containing a Seven‐Membered Ring and [7]Helicene by Acid‐Promoted Stepwise Alkyne Annulations of Doubly Axial‐Chiral Precursors**
Authors: Ikai Tomoyuki , Oki Kosuke , Yamakawa Shoya , Yashima Eiji 
Published: March 2023

AbstractEnantiopure [6]helicene containing an embedded seven‐membered ring and carbo[7]helicene (>99 % ee) with opposite helicity were simultaneously and quantitatively (>99 %) synthesized with a perfect stereospecificity through stepwise acid‐promoted intramolecular alkyne annulations of doubly axial‐chiral cyclization precursors. The helical handedness of the [6]‐ and [7]helicenes was fully stereocontrolled by the doubly axial chirality of the precursors as a result of complete axial‐to‐helical chirality transfer. The cyclizations proceeded in a stepwise manner; the first six‐membered ring formation was followed by the kinetically controlled seven‐ or six‐membered ring formation with or without helix‐inversion of a [4]helicene intermediate generated during the first cyclization step, thus quantitatively producing enantiopure circularly polarized luminescent [6]‐ and [7]helicenes with opposite helicity.
Chiral Control of Gas‐Phase Molecules using Microwave Pulses

Published: March 2023

AbstractMicrowave three‐wave mixing has emerged as a novel approach for studying chiral molecules in the gas phase. This technique employs resonant microwave pulses and is a non‐linear and coherent approach. It serves as a robust method to differentiate between the enantiomers of chiral molecules and to determine the enantiomeric excess, even in complex chiral mixtures. Besides such analytical applications, the use of tailored microwave pulses allows us to control and manipulate chirality at the molecular level. Here, an overview of some recent developments in the area of microwave three‐wave mixing and its extension to enantiomer‐selective population transfer is provided. The latter is an important step towards enantiomer separation—in energy and finally in space. In the last section, we present new experimental results on how to improve enantiomer‐selective population transfer to achieve an enantiomeric excess of about 40 % in the rotational level of interest using microwave pulses alone.
