Les activités sportives organisées représentent un contexte privilégié pour stimuler le développement positif (DP) des jeunes qui grandissent en milieu défavorisé. Cependant, les retombées positives de ces activités ne sont pas systématiques et dépendent notamment des actions et des paroles des entraîneurs qui les encadrent. On en sait peu sur la manière dont se manifestent concrètement ces pratiques. Cette étude qualitative menée auprès de 12 jeunes issus de milieux défavorisés (9 garçons; Mage = 14,08 ans) vise à répondre à deux questions : 1) Pour chacune des dimensions du DP, quelles sont les retombées des actions et des paroles des entraîneurs sportifs, telles que perçues par les jeunes? et (2) Quelles sont les actions et les paroles des entraîneurs sportifs qui, du point de vue des jeunes, engendrent ces retombées? Les résultats obtenus à partir d’analyses thématiques déductive et inductive suggèrent que les jeunes en milieu défavorisé sont tout à fait susceptibles de se développer positivement et sont en mesure de tirer profit des occasions qui leurs sont proposées, à condition que les entraîneurs valorisent l’école, offrent du soutien scolaire, fournissent des rétroactions constructives et agissent en tant que modèle positif. L’étude confirme également l’importance déjà connue des relations chaleureuses et de la prise en compte de l’opinion des jeunes. Cette étude contribue à approfondir les connaissances au sujet des actions et des paroles qui contribuent au développement positif des jeunes en milieu défavorisé.

Published: November 2023

Viruses are very minute microorganisms which are incapable of independent existence and can infect wide range of wild and cultivated plants. The plants’ reaction to viral infections are diverse and depends on factors such as the specific virus- host interaction under different environmental conditions with symptoms ranging from acting as asymptomatic carrier to showing severe diseases symptoms which further results in plant mortality. Since various viral infections can result in similar symptoms, relying solely on the disease's external appearance offers only partial insights for disease diagnosis. To achieve more precise and dependable virus identification, it is essential to consider various characteristics and properties of the virus. The molecular detection of plant viruses has revolutionized the field of plant virology. This review highlights the overview of the different approaches utilized in the diagnosis of plant viruses, with a particular focus on significant advancements in molecular techniques, ranging from traditional PCR-based methods, ELISA to high-throughput Next-Generation Sequencing (NGS) technologies. Molecular tools have enabled precise and rapid identification of plant viruses, contributing to better disease management in agriculture. The review also delves in to emerging technologies such as CRISPR- based diagnostics and nanopore sequencing, which hold promise for enhancing the precision and speed of plant virus detection.

AbstractPurposeThis study aimed to demonstrate the potential clinical applicability of an organ‐contour‐driven auto‐matching algorithm in image‐guided radiotherapy.MethodsThis study included eleven consecutive patients with cervical cancer who underwent radiotherapy in 23 or 25 fractions. Daily and reference magnetic resonance images were converted into mesh models. A weight‐based algorithm was implemented to optimize the distance between the mesh model vertices and surface of the reference model during the positioning process. Within the cost function, weight parameters were employed to prioritize specific organs for positioning. In this study, three scenarios with different weight parameters were prepared. The optimal translation and rotation values for the cervix and uterus were determined based on the calculated translations alone or in combination with rotations, with a rotation limit of ±3°. Subsequently, the coverage probabilities of the following two planning target volumes (PTV), an isotropic 5 mm and anisotropic margins derived from a previous study, were evaluated.ResultsThe percentage of translations exceeding 10 mm varied from 9% to 18% depending on the scenario. For small PTV sizes, more than 80% of all fractions had a coverage of 80% or higher. In contrast, for large PTV sizes, more than 90% of all fractions had a coverage of 95% or higher. The difference between the median coverage with translational positioning alone and that with both translational and rotational positioning was 1% or less.ConclusionThis algorithm facilitates quantitative positioning by utilizing a cost function that prioritizes organs for positioning. Consequently, consistent displacement values were algorithmically generated. This study also revealed that the impact of rotational corrections, limited to ±3°, on PTV coverage was minimal.

AbstractBioprosthetic valves are employed to replace defective heart valves. However, structural degeneration is prevalent in bioprosthetic valves because the heart valve leaflets are exposed to extreme and repetitive cardiovascular pressure. Herein, a silk fibroin‐based heart valve leaflet, which executes the physiological role of a heart valve, is developed. To this end, a templated assembly technology is developed. Notably, a physically optimal hierarchical structure for replacing the natural heart valve leaflet is realized by numerous firmly stacked β‐sheet crystals distributed within collective tyrosine‐reinforcing amorphous strands. Almost half (46.9%) of the silk fibroin‐based heart valve leaflet comprises strongly stacked β‐sheet crystals, leading to a 292% enhancement in stacking strength. The templated assembly results in the entanglement of amorphous strands, upregulating the non‐covalent interactions within the tyrosine. Consequently, the strength is enhanced by 1380% compared to native silk fibroin. Moreover, the templated assembly enhances the static and dynamic mechanical properties, thereby delivering a desirable performance for its use in heart valve replacement. Interestingly, the aortic valve composed of silk fibroin‐based leaflets does not fail under the cardiovascular pressure of 60–180 mmHg. Furthermore, the valve performance is satisfactory and surmounts the requirements of the industrial standard ISO 5840.

AbstractAnionic redox activity can trigger structural instability in Li‐rich Mn‐based cathodes. Lattice oxygen activity can be tuned through liquid acid‐induced spinel phases and oxygen vacancies. However, the liquid‐acid‐modified surface is still attacked by the electrolyte. Besides, the underlying mechanism of spinel phase suppression of lattice oxygen activity is controversial. Here, a solid acid strategy for modification is proposed and the underlying mechanism is investigated in detail. Unique solid acid can in situ generate an interface protection layer and remarkably stabilize the structure. Theoretical calculations and experimental characterizations reveal that the spinel phase suppresses the irreversible loss of lattice oxygen by decreasing the O 2p non‐bonding energy level and enriching electrons at the layered/spinel phase interface. The inert layer on the surface prevents highly active On− from being attacked by electrolytes. The obtained material exhibits significantly reduced irreversible lattice oxygen release and improved electrochemical performance. After 300 cycles, a slow capacity fading of 0.177 mAh g−1 per cycle and suppressed voltage fading are achieved. This study reveals the regulation method and mechanism for the anion activity of oxide cathodes in next‐generation Li‐ion batteries.

AbstractAs military power advances in the realm of information warfare, stealth technology has become a critical area of research for its effectiveness to evade detection. However, achieving high performance of compatible stealth across different functional mode bands remains a significant challenge. In this study, drawing inspiration from plant bionics, concepts of the directional freezing process are applied to develop a liquid metal‐MXene‐based hierarchical aerogel with radar‐infrared compatible camouflage. With a density of only 4.4 mg cm−3, the maximum reflection loss can reach −73.2 dB, and the absorption bandwidth can be adjusted up to 7 GHz. Following a thermal camouflage durability test, the sample successfully lowers the target's temperature from 400 to ≈160 °C. Remarkably, this temperature remains stable even after 180 days of exposure. Additionally, the material's ease of machining enables shape‐shifting camouflage capabilities, allowing objects to transform and resemble harmless items, thereby blending seamlessly with their surroundings. This breakthrough in compatibility performance signifies a substantial leap forward in multifunctional stealth technology development. It not only introduces innovative concepts, but also provides technical support, catalyzing further advancement in this field.

AbstractPlanar n–i–p carbon perovskite solar cells (PSCs) with a hole transport layer that can be fabricated at low temperatures at low‐cost exhibit great potential for large‐scale manufacturing. Moreover, 2D perovskites have attracted considerable attention owing to their higher stability. In this work, scalable and highly efficient fully printed large‐area carbon electrode‐based 2D perovskite modules are reported through the insertion of a thin naphthaleneimide derivative (CATNI)‐based interfacial layer between tin (IV) oxide and the perovskite layer. The results show that this facilitates the formation of the interfacial contact, suppresses energy losses, and substantially improves the performance parameters of the PSCs, especially their VOC value. A significantly enhanced VOC of 1.13 V is achieved resulting in the device PCE value reaching over 18%, which is one of the highest reported for fully printed PSCs so far. It is found that with the deployment of this CATNI‐based interfacial layer, a more efficient carrier extraction is achieved. This ultimately contributed to enhanced spectral response as well as improved VOC for these carbon electrodes based on fully printed devices. Finally, the carbon‐perovskite solar modules (carbon‐PSMs) are fabricated on ITO glass substrates with dimensions of 5.0 × 5.0 cm. These prepared modules exhibited outstanding photovoltaic performance with the highest PCE value of over 14.6%.

AbstractAll‐solid‐state lithium metal batteries can address crucial challenges regarding insufficient battery cycling life and energy density. The demonstration of long‐cycling dendrite‐free all‐solid‐state lithium metal batteries requires precise tailoring of lithium‐ion transport of solid‐state electrolytes (SSEs). In this work, a proof of concept is reported for precise tailoring of lithium‐ion transport of a halide SSE, Li3InCl6, including intragranular (within grains) but also intergranular (between grains) lithium‐ion transport. Lithium‐ion migration tailoring mechanism in crystals is developed by unexpected enhanced Li, In, and Cl vacancy populations and lower energy barrier for hopping. The lithium‐ion transport tailoring mechanism between the grains is determined by the elimination of voids between grains and the formation of unexpected supersonic conducting grain boundaries, boosting the lithium dendrite suppression ability of SSE. Due to boosted lithium‐ion conduction and dendrite‐suppression ability, the all‐solid‐state lithium metal batteries coupled with Ni‐rich LiNi0.83Co0.12Mn0.05O2 cathodes and lithium metal anodes demonstrate breakthroughs in electrochemical performance by achieving extremely long cycling life at a high current density of 0.5 C (2000 cycles, 93.7% capacity retention). This concept of precise tailoring of lithium‐ion transport provides a cost, time, and energy efficient solution to conquer the remaining challenges in all‐solid‐state lithium‐metal batteries for fast developing electric vehicle markets.

AbstractThe management of diabetes in a manner offering autonomous insulin therapy responsive to glucose‐directed need, and moreover with a dosing schedule amenable to facile administration, remains an ongoing goal to improve the standard of care. While basal insulins with reduced dosing frequency, even once‐weekly administration, are on the horizon, there is still no approved therapy that offers glucose‐responsive insulin function. Herein, a nanoscale complex combining both electrostatic‐ and dynamic‐covalent interactions between a synthetic dendrimer carrier and an insulin analogue modified with a high‐affinity glucose‐binding motif yields an injectable insulin depot affording both glucose‐directed and long‐lasting insulin availability. Following a single injection, it is even possible to control blood glucose for at least one week in diabetic swine subjected to daily oral glucose challenges. Measurements of serum insulin concentration in response to challenge show increases in insulin corresponding to elevated blood glucose levels, an uncommon finding even in preclinical work on glucose‐responsive insulin. Accordingly, the subcutaneous nanocomplex that results from combining electrostatic‐ and dynamic‐covalent interactions between a modified insulin and a synthetic dendrimer carrier affords a glucose‐responsive insulin depot for week‐long control following a single routine injection.

AbstractGiant dimeric acceptor (G‐Dimer) is becoming one of the most promising organic solar cell (OSC) materials because of its definite structure, long‐term stability, and high efficiency. Strengthening the hetero‐molecular interactions by monomer modification greatly influences the morphology and thus the device performance, but lacks investigation. Herein, two novel quinoxaline core‐based G‐Dimers, Dimer‐QX and Dimer‐2CF, are synthesized. By comparing trifluoromethyl‐substituted Dimer‐2CF and non‐substituted Dimer‐QX, the trifluoromethylation effect on the G‐Dimer is investigated and revealed. The trifluoromethyl with strong electronegativity increases electrostatic potential and reduces surface energy of the G‐Dimer, weakening the homo‐molecular ordered packing but reinforcing the hetero‐molecular interaction with the donor. The strong hetero‐molecular interaction suppresses the fast assembly during the film formation, facilitating small domains with ordered molecular packing in the blend, which is a trade‐off in conventional morphology control. Together with favorable vertical phase separation, efficient charge generation, and reduced bimolecular recombination are concurrently obtained. Hence, the Dimer‐2CF‐based OSCs obtain a cutting‐edge efficiency of 19.02% with fill factor surpassing 80%, and an averaged extrapolated T80 of ≈12 000 h under continuous 80 °C heating. This study emphasizes the importance of hetero‐molecular interaction and trifluoromethylation strategy, providing a facile strategy for designing highly efficient and stable OSC materials.

AbstractThree nonfused ring electron acceptors (NFREAs), namely, 3TT‐C2‐F, 3TT‐C2‐Cl, and 3TT‐C2, are purposefully designed and synthesized with the concept of halogenation. The incorporation of F or/and Cl atoms into the molecular structure (3TT‐C2‐F and 3TT‐C2‐Cl) enhances the π–π stacking, improves electron mobility, and regulates the nanofiber morphology of blend films, thus facilitating the exciton dissociation and charge transport. In particular, blend films based on D18:3TT‐C2‐F demonstrate a high charge mobility, an extended exciton diffusion distance, and a well‐formed nanofiber network. These factors contribute to devices with a remarkable power conversion efficiency of 17.19%, surpassing that of 3TT‐C2‐Cl (16.17%) and 3TT‐C2 (15.42%). To the best of knowledge, this represents the highest efficiency achieved in NFREA‐based devices up to now. These results highlight the potential of halogenation in NFREAs as a promising approach to enhance the performance of organic solar cells.
Pd(0)‐Catalyzed‐Mediated Synthesis of Vitamin D Compounds
Authors: Mouriño Antonio 
Published: November 2023

Abstract1α,25‐Dihydroxyvitamin D3 (1,25D3), the hormonally active form of vitamin D3, regulates mineral homeostasis, cell growth, cell differentiation‐proliferation, apoptosis, and immune responses. 1,25D3 activates more than 229 genes associated with several diseases, including arthritis, diabetes and cancer, suggesting its implications in a broader range of biological functions than originally thought. Despite the wide range of biological activities, the clinical applications of 1,25D3 have been limited due to its collateral hypercalcemic effects. This problem has boosted intense synthetic activity in the vitamin D area in the last decades aimed at the development of highly active and non‐calcemic analogs for treatment of hyperproliferative diseases. This review covers the most useful synthetic approaches to 1,25D3 analogs containing the natural vitamin D triene system with emphasis on the Pd(0)‐catalyzed transformations involved in the formation of the vitamin D triene system and A‐ring synthons.

AbstractBackgroundStandard surgery for upper advanced gastric cancer without invasion of the greater curvature (UGC‐GC) is spleen‐preserving D2 total gastrectomy without dissection of the splenic‐hilar nodes (#10). However, some patients with nodal metastasis to #10 survive more than 5 years due to nodal dissection of #10. If nodal metastasis to #10 is predictable based on the positivity of other nodes dissected by the current standard surgery without #10 nodal dissection, physicians may be able to consider #10 dissection.MethodsThis study retrospectively reviewed data from the National Cancer Center Hospital in Japan between 2000 and 2012. We selected cases that met the following criteria: (1) D2 or more total gastrectomy with splenectomy, (2) UGC‐GC, and (3) histological type is gastric adenocarcinoma. We performed univariate and multivariate analyses concerning lymph node stations associated with #10 metastasis.ResultsA total of 366 patients were examined. A multivariate analysis revealed that #10 metastasis was associated with positivity of the nodes along the short gastric arteries (#4sa) and distal nodes along the splenic artery (#11d) (#4sa: p = 0.003, #11d: p = 0.016). When either key node was positive, the metastatic rate of #10 was 24.4%, and the therapeutic value index was 13.3.Conclusions#4sa and #11d were key lymph nodes predicting #10 nodal metastasis in UGC‐GC. When these key nodes are positive on computed tomography before surgery or according to a rapid pathological examination during surgery, dissection of #10 should be considered even if upper advanced tumors are not invading the greater curvature.
Unusual phosphorescence of boric acid: From impurity or clusterization‐triggered emission?

Published: November 2023

AbstractThe unusual room‐temperature phosphorescence (RTP) from the n electron‐rich systems (without regular conjugated structure) has aroused great attention for structural designing and application development of RTP materials. Such emission has been ascribed to clusterization‐triggered emission (CTE) via weak through‐space conjugation of n electrons in the heteroatoms. However, there was suspicion on such RTP as impurity‐induced result. Therefore, in‐depth photophysical investigation and effective proof methods are needed to trace the origin of such RTP. Here, using the recently reported CTE phosphor boric acid as the example, a Jablonski diagram‐based verification protocol was proposed to confirm the intrinsic luminescence of the n electrons‐rich systems. Meanwhile, some other types of luminophores, that is, traditional phosphors, already reported impurity‐induced and host‐guest doping luminophores, were included for comparison. Overall, this work provides a basic paradigm for differentiating between the impurity‐involved and the n electron‐rich phosphors and will further deepen the understanding of nonconventional luminescence.
