Martyre protestant
Authors: Gutton Philippe 
Published: April 2011

Par le martyre, les protestants témoignent de leurs expériences religieuses telles qu’ils l’élaborent face au dogme et au pouvoir de l’Église de Rome. Dans cette optique le fait majeur est la traduction en français de la Bible et son enseignement par les prédicateurs. Elle est une cause fondamentale de la réforme en ouvrant à chaque chrétien, de façon démocratique les interprétations de leurs croyances et dès lors le heurt de celles-ci avec les convictions instituées. La compréhension de la « présence réelle du Christ dans l’eucharistie par Calvin » se révèle à la lecture de son petit traité une affaire moins théologique que politique.
Le martyre : la dialectique du vivre et du mourir
Authors: Lemoine Laurent 
Published: April 2011

Pouvoir parler du martyre aujourd’hui dans un travail d’interface entre confessions religieuses et psychanalyse est une possibilité stimulante qui ne correspond déjà plus au contexte d’il y a dix ans. En effet, de nos jours, le retour de croyances communautariennes devient massif. Quels sont les points communs et les divergences entre deux itinéraires de martyr apparemment éloignés, celui d’Antigone, d’une part, et celui, de Maximilien Kolbe mort en déportation à Auschwitz en août 1942 ? D’autre part, comment s’y joue, dans les deux cas, la dialectique du vivre et du mourir ? C’est ce que ce texte a tenté de travailler.
D'une guerre à l'autre : le sacrifice
Authors: de Mijolla-Mellor Sophie 
Published: April 2011

La mort héroïque est une « anti-mort » qui est vainqueur de la mort parce qu’elle lui impose un sens qu’elle n’aurait pas d’elle-même. La sublimation de ceux qui s’y engagent leur offre le sentiment de vivre une aventure humaine qu’aucune activité ne pourrait leur offrir et s’inscrit non pas dans le renoncement et la perte mais au contraire dans le gain de sens.

ImportanceDisturbances in maternal, placental, and fetal metabolism are associated with developmental outcomes. Associations of maternal, placental, and fetal metabolism with subsequent neurodevelopmental outcomes in the child are understudied.ObjectiveTo investigate the metabolic associations within the maternal-placental-fetal unit and subsequent neurodevelopmental outcomes in younger siblings of children with autism spectrum disorder (ASD).Design, Setting, and ParticipantsThis cohort study was conducted within a subset of the Markers of Autism Risk in Babies, Learning Early Signs (MARBLES) cohort. MARBLES is a prospective birth cohort of younger siblings of children with ASD assessed for neurodevelopmental outcomes at approximately age 36 months. Participants in MARBLES were recruited through the UC Davis MIND Institute. This subset of the MARBLES cohort included younger siblings born between 2009 and 2015. Maternal third trimester serum, placental tissue, and umbilical cord serum samples were collected from participants. Only pregnancies with at least 2 of these sample types were included in this analysis. Data analysis was conducted from March 1, 2023, to March 15, 2024.ExposuresQuantitative metabolomics analysis was conducted on maternal third trimester serum, as well as placental tissue and umbilical cord serum collected at delivery.Main Outcomes and MeasuresUsing the Autism Diagnostic Observation Schedule and Mullen Scales of Early Learning, outcomes were classified as ASD, other nontypical development (non-TD), and typical development (TD).ResultsThis analysis included 100 maternal serum samples, 141 placental samples, and 124 umbilical cord serum samples from 152 pregnancies (median [IQR] maternal age, 34.6 [30.8-38.3] years; median [IQR] gestational age, 39.0 [38.6-39.7] weeks; 87 [57.2%] male infants). There was no evidence that the maternal third trimester serum metabolome was significantly associated with the other metabolomes. The placental and cord serum metabolomes were highly correlated (first latent variate pair: R2 = 0.75; P &amp;lt; .001) and the variate scores for each tissue were significantly associated with reduced risk of non-TD (placenta: relative risk [RR], 0.13; 95% CI, 0.02-0.71; cord: RR, 0.13; 95% CI, 0.03-0.70) but not ASD (placenta: RR, 1.09; 95% CI, 0.42-2.81; cord: RR, 0.63; 95% CI, 0.23-1.73) compared with the TD reference group.Conclusions and RelevanceIn this cohort study of children with high familial risk of ASD, placental and cord serum metabolism at delivery were highly correlated. Furthermore, placental and cord serum metabolic profiles were associated with risk of non-TD.

AbstractReverse electrodialysis (RED) technology, relying on ion‐selective permeability membranes (ISPM), offers a direct means of harnessing osmotic energy from the salinity difference between seawater and freshwater. Critical technical challenges include limitations in ISPM's immobile charge carriers, transmembrane ionic internal resistance, and durability in water. Drawing inspiration from the subunit structure of the epithelial sodium channel (ENaC), an ISPM assembled using a supramolecular engineering strategy is introduced. This innovative approach enables the synergistic action of multiple molecular building blocks to mimic the distribution of ENaC subunit structures, strategically planning the placement of immobile charge carriers on nanofluidic channels. The design incorporates nano‐confined oxygen‐rich functionalized MXene (O‐MXene) and high‐strength polymer backbone aramid fibers to construct 3D nanofluidic channels with a high surface charge density. Enhanced by a bonding network of sodium carboxymethylcellulose, the ISPM achieved an exceptional output power density of 21.7 W m−2 and 46.0% energy conversion efficiency in a RED half‐cell system using natural seawater and river water, surpassing current technologies. This research not only advances RED technology but also provides biomimetic customization concepts for ISPM design across various applications, including flow batteries, fuel cells, and related fields.

AbstractSolid‐state molecular arrangement has been recognized as the most important role in the charge transport properties of organic semiconductors. Although highly ordered molecular stacking is achieved in single crystals, maintaining single‐crystal molecular packing in solution‐processed thin films remains a significant challenge. Herein, a new type of n‐type organic semiconductors based on an asymmetric fluoranthene imide unit is reported, whose intermolecular packing and aggregation behavior in the thin film state can be effectively controlled by regulating the cyano substitution sites and alkyl chain types in the imide group. F10 with cyano groups at 4,9‐sites and branched 2‐ethylhexyl chain encouragingly shows a highly ordered single‐crystal‐like molecular packing in solution‐processed thin film after thermal annealing, and thus the resulting organic field‐effect transistors exhibit impressive charge transport performance, with the electron mobility as high as 0.116 cm2 V−1 s−1. This work opens a new avenue for developing high‐performance solution‐processed n‐type semiconductors.

Published: May 2024

AbstractPhotonic‐ionic skins (PI‐skins) featuring multi‐signal synergistic outputs exhibit fascinating interactive sensing potential in flexible iononics. However, the existing ones are susceptible to irreversible damage in usage due to their poor toughness and deficiency in self‐healing. Herein, a novel tough mechanochromic PI‐skin is ingeniously constructed, from both molecular engineering and nanostructural engineering perspectives, via integrating the ordered photonic array and robust metal‐imidazole cross‐linked network. The PI‐skin displays synchronous structural color variation and sensitive electrical response under strain. Notably, the synergy of dense physical cross‐linking network and microphase‐separation structure achieved by strong metal‐imidazole coordination greatly promotes energy dissipation. PI‐skin possesses a combination of exceptional properties, including high fracture strength (8.22 MPa), remarkable toughness (10.23 MJ m−3), and robust adhesion behavior (2.30 MPa). Furthermore, favorable self‐healing capability at room temperature is realized thanks to the dynamic topological rearrangement of metal‐imidazole coordination. The PI‐skin demonstrates promising uses as a visually interactive wearable device for human motion monitoring and remote communication. This work not only broadens design considerations for the development of high‐performance artificial skins but also offers a general optical platform for high‐level interactive wearable devices.

AbstractIncreasing the upper cut‐off voltage of the LiNixCoyMn1‐x‐yO2 (NCM)‐based lithium‐metal batteries (LMBs) is highly pursued for achieving high battery energy density. However, the cycling stability of high‐voltage LMBs, which is associated with ethylene carbonate electrolytes, remains greatly challenging. Herein, an interphase‐designable additive‐enabled ethylene carbonate‐free electrolyte strategy is proposed for achieving 4.6 V Li||NCM811 battery with long cycling life from 55 to −30 °C. The solvent characteristics of ethyl methyl carbonate endow LMBs with potential merits in high voltage, wide temperature, and cycling stability, which are further strengthened by the additive, 1,5‐difluoro‐2,4‐dinitrobenzene (FNB), for optimizing electrode electrolyte interphases. The sturdy LiF‐rich and LiNxOy‐contained electrode/electrolyte interphase on cathode/anode surfaces can protect two electrodes well from electrolyte corrosion and also reduce excessive electrolyte decomposition. As expected, the Li||NCM811 batteries can maintain 70% capacity retention after 500 cycles with superior high‐temperature and low‐temperature performance (from 55 to −30 °C). The 6.8Ah pouch cells with this electrolyte can achieve a high energy density of up to 505 Wh kg−1.

Abstract2D semiconductor nanomaterials have received significant attention as photocatalysts for solar‐to‐hydrogen conversion due to their robust light absorption capacity, large specific surface area, and superior electron transport characteristics. Nevertheless, it is challenging to develop 2D quaternary copper‐based sulfides (QCSs) with functional integration of conducive structural features for photocatalysis from multiple elements and intricate control conditions. Herein, ultrathin 2D alloyed Cu−Ga−Zn−S (CGZS) curved nanobelts (NBs) are fabricated by using a facile one‐pot colloidal method. Subsequently, the derived Cu31S16‐CGZS Janus heterostructures are designed by increasing Cu concentrations. The formation mechanism of 2D curved alloys and Janus heterostructures is systematically investigated. Without cocatalysts, curved alloyed CGZS NBs demonstrated superior photocatalytic activities of 1264.2 µmol g−1 h−1 compared to Janus heterostructured Cu31S16−CGZS (463.1 µmol g−1 h−1) under visible light (> 400 nm). Experimental and theoretical results unveiled that the improved photocatalytic activities of curved CGZS NBs can be attributed to enhanced charge–carrier separation efficiency resulting from high crystallinity and ultrathin 2D structure, abundant active sites from curved structure, high‐active (0001) crystal facet with the lowest reaction Gibbs energy, work function, and metal‐like properties. This work offers new insights into functional integration into ultrathin 2D QCSs with enhanced visible‐light photocatalytic performance.
Nanoclay Mediated Self‐Promoted Reactive Oxygen Species Releasing Enables Efficient Antimicrobial

Published: May 2024

AbstractReactive oxygen species (ROS) releasing materials are increasingly used in nanomedicines due to their effectiveness against a broad spectrum of microbes. However, most ROS‐releasing materials rely on external stimuli such as photoirradiation, either through photodynamic or photocatalytic processes, which limits their practical applications. Herein, this work presents a novel nanoclay mediated self‐promoted ROS releasing material called oxygen vacancies‐rich ZnO/kaolinite (Ov‐rich ZnO/Kaol). Both experiments and density functional theory (DFT) calculations reveal that the introduction of kaolinite increases the content of Ov in ZnO, and the change in the electronic structure promotes the process of oxygen adsorption and activation, resulting in the generation of ·O2−through oxygen reduction without photoirradiation. Molecular dynamics simulations confirm that Ov enhances the interaction between the material and bacterial membrane, promoting the bacterial‐killing effect of ·O2−. More importantly, Ov‐rich ZnO/Kaol is successfully prepared on a pilot scale and used to manufacture antibacterial gauze, which showed at least 99% antibacterial activity against both Escherichia coli (E. coli) and Staphylococcus aureus (S. aureus) in the absence of light. The as‐prepared material also exhibited satisfactory biocompatibility and biosafety. This method can offer a more benign approach to address the limitations of traditional photoirradiation‐dependent photosensitizers for antimicrobial gauze.

Published: May 2024

Transition metal sulfides with designed nanostructures are expected to provide superior electrochemical performance when used as electrode materials for pseudocapacitors compared to their oxide counterparts. In this paper, hollow Co3S4 dodecahedra were successfully prepared using cobalt‐based zeolite imidazolium skeleton (ZIF‐67) as the precursor and thioacetamide (TAA) as the sulfur source combined with a facile one‐step vulcanization process. The hollow cavity structure not only shortens the carrier transport distance but also provides a higher specific surface area and abundant active sites, which promotes an efficient mass transfer process. In addition, the one‐step synthesis of hollow Co3S4 has greater advantages than the one‐step synthesis in terms of cost control and process simplification. The specific capacitance of the produced hollow Co3S4 nanopolyhedra was 668 F/g at 1 A/g and remained at 353 F/g at 10 A/g when used as a pseudocapacitor electrode, demonstrating its superior multiplication capability. In addition, the capacitance retention is 86.4% after 5000 cycles at 4 A/g, indicating its long cycle stability. Notably, employing commercial activated carbon as negative electrode and the as‐prepared hollow Co3S4 polyhedrons as positive electrode, the assembled asymmetry supercapacitor device delivers a high energy density of 20.7 Wh/kg at a power density of 716 kW/kg. The capacitance value of the device remains up to 81.4% after 2000 charging/discharging cycles. The simple synthesis process opens new opportunities to develop advanced hollow nanostructures exhibiting potential for various applications.

AbstractSkeletal muscle (SkM) is a plastic and dynamic tissue, essential in energy metabolism. Growing evidence suggests a close relationship between intramuscular fat accumulation, oxidative stress (OS), extracellular matrix (ECM) remodeling, and metabolic deregulation in SkM. Nowadays natural products emerge as promising alternatives for the treatment of metabolic disorders. We have previously shown that chia seed administration reverts SkM lipotoxicity and whole‐body insulin resistant (IR) in sucrose‐rich diet (SRD) fed rats. The purpose of the present study was to assess the involvement of OS and fibrosis in SkM metabolic impairment of insulin‐resistant rats fed a long‐term SRD and the effects of chia seed upon these mechanisms as therapeutic strategy. Results showed that insulin‐resistant SRD‐fed rats exhibited sarcopenia, increase in lipid peroxidation, altered redox state, and ECM remodeling‐increased collagen deposition and lower activity of the metalloproteinase 2 (MMP‐2) in SkM. Chia seed increased ferric ion reducing antioxidant power and glutathione reduced form levels, and the activities of glutathione peroxidase and glutathione reductase enzymes. Moreover, chia seed reversed fibrosis and restored the MMP‐2 activity. This work reveals a participation of the OS and ECM remodeling in the metabolic alterations of SkM in our experimental model. Moreover, current data show novel properties of chia seed with the potential to attenuate SkM OS and fibrosis, hallmark of insulin‐resistant muscle.

AbstractAdenylation enzymes catalyze the selective incorporation of aminoacyl building blocks in the biosynthesis of nonribosomal peptides and related natural products. Although β‐amino acid units are one of the important aminoacyl building blocks in natural product biosynthesis, very little is known about the engineering of β‐amino acid adenylation enzymes. In this study, we engineered the substrate specificity of the (S)‐β‐phenylalanine adenylation enzyme, HitB, involved in the biosynthesis of macrolactam polyketide hitachimycin. Based on the previously determined structure of HitB wild‐type, we mutated Phe328 and Ser293, which are located near the meta and ortho position of the (S)‐β‐phenylalanine moiety, respectively. As a result, the HitB F328V and F328L mutants efficiently activated meta‐substituted (S)‐β‐phenylalanine analogs, and the HitB T293G and T293S mutants efficiently activated ortho‐substituted (S)‐β‐phenylalanine analogs. Structural analysis of the HitB F328L and T293G mutants with the corresponding nonhydrolyzable intermediate analogs revealed an enlarged substrate binding pocket for (S)‐β‐phenylalanine analogs, providing detailed insights into the structural basis for creating enzyme substrate promiscuity. Our findings may be useful for production of various β‐amino acid‐containing natural product analogs.

Published: May 2024

AbstractSelf‐assembly of chromophoric systems is a prerequisite to create well‐ordered, processable nanomaterials with multiple functionalities. In the past two decades, the field of functional organic materials has primarily focused on systems featuring only one type of dye/π‐conjugated unit. Consequently, many reports with mechanistic insights on the self‐assembly of the dyes featuring different molecular packing have been reported. Subsequently, we have witnessed several attempts to organize the multi‐chromophoric systems in solution and solid‐state via different approaches using self‐assembly as a tool. Incorporation of more than one dye is important in creating materials with tuneable optoelectronic properties. Consequently, self‐assembly of more than one chromophoric systems have been investigated to some extent. This review aims to discuss the self‐assembled materials derived from discrete π‐conjugated systems comprising more than one dye units connected through covalent bonding (multi‐chromophoric systems). Molecular design of various multi‐chromophoric systems leading to the formation of crystals, liquid crystals and supramolecular polymers have been correlated with corresponding properties. We envisage that classification of self‐assembled multi‐chromophoric systems, with a note on tuneable optoelectronic properties, can provide a deeper understanding on the molecular design strategies, which is important in the fabrication of functional organic materials with optimum performances.

AbstractImines are essential intermediates in organic transformations, and is generally produced by dehydrogenative condensation of alcohols and amines with the assist of specialized catalysts and additives. Heterogeneous photocatalysis provides a sustainable platform for such process without the using of toxic oxidants, yet a functionalized photocatalyst with optimized co‐adsorption of reactants needs to be developed to promote the stoichiometric oxidative condensation under ambient conditions. Here, we show that benzyl alcohol and aniline adsorb non‐interferingly on the Fe node and the linker sites of the MIL‐53(Fe) metal organic frameworks (MOFs), respectively. The co‐adsorption of both reactants barely influences the reduction of molecular oxygen to generate oxygen radicals, resulting in efficient formation of benzaldehyde under visible light. Additionally, the weak adsorption of water together with surface acidity of the MIL‐53(Fe) promote a rapid condensation of benzaldehyde with aniline and the depletion of generated water, achieving an efficient C−N bond creation for a wide range of substrates.

AbstractThe abiotic synthesis of peptides, widely regarded as one of the key chemical reactions on the prebiotic Earth, is thermodynamically constrained in solution. Herein, a simulation of the lightning phenomenon on the sea surface using bubble bursting and arc plasma under ambient conditions enables dipeptide formation of six amino acids with conversion ratios ranging from 2.6 % to 25.5 %. Additionally, we observed the formation of biologically active tripeptides and investigated the stereoselectivity of the dipeptide formation reaction. By utilizing a mixture of 20 amino acids in the reaction, 102 possible dipeptides were generated. These results establish experimental constructions to mimic achievable prebiotic conditions and provide a credible pathway for endogenous biopolymer synthesis on prebiotic Earth.
