Confier la lettre au cinéma : lecture du parcours intermédial des missives maternelles dans News from Home (1977) de Chantal Akerman
Authors: Lamoureux Frédérique 
Published: May 2023

Cette lecture-spectature intermédiale du film News from Home (1977) de Chantal Akerman propose de penser le trajet de la lettre (de la mère à la fille, de l’écrit à la lecture, du papier à l’écran) et ses différentes médiations en considérant l’échange épistolaire comme lieu intime de confidence et de confiance, mais aussi d’inquiétude, d’incertitude puisque si le telos des lettres est d’abolir la distance entre mère et fille, la transaction qu’elles instaurent intensifie paradoxalement le poids de l’absence (Foucart, 2018). À la lumière des réflexions de Jacques Lacan, Michela Marzano et Jacques Derrida, j’aborderai d’abord les connexions intersubjectives et la relation de confiance qu’établissent la correspondance et sa médiation filmique. Je m’intéresserai ensuite aux enjeux de mémoire et d’héritage que soulève le devenir-public des lettres en dialoguant avec la notion de « secret » développée par la psychanalyste Anne Dufourmantelle dans son essai Défense du secret (2015).
Rottnest Island Peafowl Pavo cristatus - a colourful history comes to an end

Published: May 2023

ABSTRACT
During the early 1900s, the Acclimatization Committee of Western Australia introduced several species to Rottnest Island, most of which ultimately failed to establish. The Indian Peafowl Pavo cristatus was one that was successful and became synonymous with visits to the island. Peafowl eventually became too much of a nuisance and in 2009 the population was reduced by the Rottnest Island Authority leaving just male birds. In April 2022 the last peafowl died. We present the history of peafowl on Rottnest Island and describe how the introduced species' residence on Rottnest Island came to end.

Introduction: Benign intracardiac tumours are the most common of the 5% of primary tumours and account for 90% of intracardiac tumours. Myxoma, which is the main benign tumour, rarely localizes to the mitral valve, in the order of 1-5%, associated with severe symptoms and enormous complications.
The objective is to report a rare and severe case of mitral valve myxoma resulting in severe obstruction of the valve orifice.
Presentation of Case: A 65-year-old Moroccan woman, without profession, the diabetic patient presented with progressive dyspnoea, in whom transthoracic echocardiography (TTE) completed by transesophageal echocardiography (TEE), a cardiac magnetic resonance imaging (MRI), a cerebro-throracoabdominopelvic Positron emission tomography-scan (PET-scan) showed a cauliflower-shaped mass embedded in the small mitral valve, evoking the diagnosis of myxoma, confirmed by the anatomopathological examination. A lumpectomy with mitral valve plasty was performed in association with coronary artery bypass surgery for a tri truncal lesion. The evolution was marked by an improvement in the clinical and echographic state.
Discussion: Myxoma is the first benign tumour encountered in women between the 3rd and 6th decade, whose diagnosis is evoked by a TTE, better by a TEE or more, by a computed tomography (CT scan) or even a cardiac MRI which specifies the visualization of the soft parts with all the internal details of the myxoma, whose confirmation is carried out on the histopathological analysis of the operating room.
Conclusion: The management was based on complete resection of the tumor associated with mitral valve plasty.

Aim: The aim of this study is to generate and investigate oral bioaccessibility based on the health risk of polycyclic aromatic hydrocarbon (PAHs) in fly ash from waste tyres and petroleum products in Rivers State, Nigeria.
Study Design: Crude oil, crude oil asphalt, artisanal diesel, refined diesel, waste engine oil and waste tyres samples were collected and incinerated. The different fly ash samples were analyzed with GC-MS.
Place and Duration of Study: Rivers State is a state that is rich in oil in the Niger Delta area of Nigeria. The State has been experiencing the release of soot into the environment for more than five (5) years now. This soot is noticeable to all residents of Port Harcourt and its environment with soot covering both indoor and outdoor objects such as clothes, cars, houses, floors, soil, water body, etc. The five (5) petroleum products and waste tyres samples were collected and incinerated for six (6) weeks (22nd of June to 7th of August 2021).
Methodology: The petroleum products and waste tyres samples were collected and incinerated. The different fly ash samples were collected after combustion daily. The total and oral bioaccessible PAH concentrations were determined using GC-MS. The oral bioaccessibility of PAHs in the fly ash was evaluated using the physiologically-based extraction test method (PBET) to determine the bioaccessible concentrations of 16 priority US Environmental Protection Agency (USEPA) PAHs in fly ash samples. The results obtained for PAHs were used for health risk assessment.
Results: A wider range of total PAH concentrations were observed in the six (6) fly ash samples from 49.71 to 926.62 mg/kg. The PAHs concentrations were significantly higher in higher molecular weight PAHs (with benzene of 4-5-6 rings) than lower molecular weight PAHs (benzene of 2-3 rings). Naphthalene, acenaphthylene, acenaphthene, and fluorene with 2-3 ring structures had the highest bioaccessible concentrations in both gastric and gastrointestinal phases of all the six fly ash samples studied. Flourene had the maximum percentage bioaccessibility of 91.30 % in the gastric phase from locally refined diesel fly ash whilst acenaphthene had a maximum percentage bioaccessibility of 98.75% in the gastrointestinal phase from crude oil asphalt fly ash.
Conclusion: Data obtained from this study indicated that crude oil fly ash is a potential point source of toxic polycyclic aromatic hydrocarbons with significant levels of health risk to humans.

AbstractMachine learning has proven useful in analyzing complex biological data and has greatly influenced the course of research in structural biology and precision medicine. Deep neural network models oftentimes fail to predict the structure of complex proteins and are heavily dependent on experimentally determined structures for their training and validation. Single‐particle cryogenic electron microscopy (cryoEM) is also advancing the understanding of biology and will be needed to complement these models by continuously supplying high‐quality experimentally validated structures for improvements in prediction quality. In this perspective, the significance of structure prediction methods is highlighted, but the authors also ask, what if these programs cannot accurately predict a protein structure important for preventing disease? The role of cryoEM is discussed to help fill the gaps left by artificial intelligence predictive models in resolving targetable proteins and protein complexes that will pave the way for personalized therapeutics.

AbstractA conductive engineered cardiac patch (ECP) can reconstruct the biomimetic regenerative microenvironment of an infarcted myocardium. Direct ink writing (DIW) and 3D printing can produce an ECP with precisely controlled microarchitectures. However, developing a printed ECP with high conductivity and flexibility for gapless attachment to conform to epicardial geometry remains a challenge. Herein, an asymmetrical DIW hydrophobic/hydrophilic membrane using heat‐processed graphene oxide (GO) ink is developed. The “Masked spin coating” method is also developed that leads to a microscale GO (hydrophilic)/reduced GO (rGO, hydrophobic) physiological sensor, as well as a macroscale moisture‐driven GO/rGO actuator. Depositing mussel‐inspired polydopamine (PDA) coating on the one side of the DIW rGO , the ultrathin (approximately 500 nm) PDA‐rGO (hydrophilic)/rGO (hydrophobic) microlattice (DrGOM) ECP is bestowed with the flexibility and moisture‐responsive actuation that allows gapless attachment to the curved surface of the epicardium. Conformable DrGOM exhibits a promising therapeutic effect on rats' infarcted hearts through conductive microenvironment reconstruction and improved neovascularization.

AbstractGreen electronics made from degradable materials have recently attracted special attention, because electronic waste (e‐waste) represents a serious threat to the environment and to human health worldwide. Among the novel materials used for sustainable technologies, nanocelluloses containing at least 1D in the nanoscale range (1–100 nm) have been widely exploited for various industrial applications owing to their inherent properties, such as biodegradability, mechanical strength, thermal stability, and optical transparency. This review highlights recent advances in research on the development of patterns for conductive material on nanocellulose substrates for use in high‐performance green electronics. The advantages of nanocellulose substrates compared to conventional paper substrates for advanced green electronics are discussed. Importantly, this review emphasizes various fabrication strategies for producing conductive patterns on different types of nanocellulose‐based substrates, such as cellulose nanofiber (CNF), (2,2,6,6‐tetramethylpiperidin‐1‐yl)oxyl(TEMPO)‐oxidized CNF, regenerated cellulose, and bacterial cellulose. In the latter part of this review, emerging engineering applications for green electronics such as circuits, transistors/antennas, sensors, energy storage systems, and electrochromic devices are further discussed.

Published: May 2023

AbstractThe ionic conductivity of anion exchange membranes (AEMs) directly determines the performance of anion exchange membrane fuel cells (AEMFCs), which highly depends on the hydration level of the membrane. A better understanding of the relationship between hydration level and membrane ionic conductivity is essential for membrane development and for water and thermal management analyses of AEMFCs. In this study, the effects of water activity and temperature on water uptake, equilibrium water content, and ionic conductivity of three high‐performance AEMs (Alkymer, Orion, and Pention) are quantitatively characterized via the designed experiments. The results show that Orion exhibits the lowest water uptake and highest ionic conductivity among the three membranes at high water activity and Alkymer exhibits good water‐retention capability and the highest ionic conductivity at low water activity. Empirical equations combining water activity and equilibrium water content are proposed based on fitted experimental data to define the hydration level. Empirical equations combining ionic conductivity, equilibrium water content, and temperature are fitted to illustrate the relationship between ionic conductivity and hydration level. The findings of this study can provide solid guidelines and support for the future experimental characterization and water and thermal management analyses of AEMFCs.

Published: May 2023

AbstractHarvesting water from air in sorption‐based devices is a promising solution to decentralized water production, aiming for providing potable water anywhere, anytime. This technology involves a series of coupled processes occurring at distinct length scales, ranging from nanometer to meter and even larger, including water sorption/desorption at the nanoscale, condensation at the mesoscale, device development at the macroscale and water scarcity assessment at the global scale. Comprehensive understanding and bespoke designs at every scale are thus needed to improve the water‐harvesting performance. For this purpose, a brief introduction of the global water crisis and its key characteristics is provided to clarify the impact potential and design criteria of water harvesters. Next the latest molecular‐level optimizations of sorbents for efficient moisture capture and release are discussed. Then, novel microstructuring of surfaces to enhance dropwise condensation, which is favorable for atmospheric water generation, is shown. After that, system‐level optimizations of sorbent‐assisted water harvesters to achieve high‐yield, energy‐efficient, and low‐cost water harvesting are highlighted. Finally, future directions toward practical sorption‐based atmospheric water harvesting are outlined.

AbstractNarrow‐bandgap (NBG) mixed tin/lead‐based (Sn‐Pb) perovskite solar cells (PSCs) have attracted extensive attention for use in tandem solar cells. However, they are still plagued by serious carrier recombination due to inferior film properties resulting from the alloying of Sn with Pb elements, which leads to p‐type self‐doping behaviors. This work reports an effective tin oxide (SnOx) doping strategy to produce high‐quality Sn‐Pb perovskite films for utilization in efficient single‐junction and tandem PSCs. SnOx can be naturally oxidized from tin diiodide raw powders and successfully incorporated into Sn‐Pb perovskite films. Consequently, Sn‐Pb perovskite films doped with SnOx exhibit dramatically improved morphology, crystallization, absorption, and more interestingly, upward‐shifted Fermi levels. The resulting narrow‐bandgap Sn‐Pb PSCs with natural SnOx doping have considerably reduced carrier recombination, therefore delivering a maximum power conversion efficiency (PCE) of 22.16% for single‐junction cells and a remarkable PCE of 26.01% (with a steady‐state efficiency of 25.33%) for two‐terminal all‐perovskite tandem cells. This work introduces a facile doping strategy for the manufacture of efficient single‐junction narrow‐bandgap PSCs and their tandem solar cells.

AbstractTransition metal dichalcogenide (TMD) coatings have attracted enormous scientific and industrial interest due to their outstanding tribological behavior. The paradigmatic example is MoS2, even though selenides and tellurides have demonstrated superior tribological properties. Here, an innovative in operando conversion of Se nanopowders into lubricious 2D selenides, by sprinkling them onto sliding metallic surfaces coated with Mo and W thin films, is described. Advanced material characterization confirms the tribochemical formation of a thin tribofilm containing selenides, reducing the coefficient of friction down to below 0.1 in ambient air, levels typically reached using fully formulated oils. Ab initio molecular dynamics simulations under tribological conditions reveal the atomistic mechanisms that result in the shear‐induced synthesis of selenide monolayers from nanopowders. The use of Se nanopowder provides thermal stability and prevents outgassing in vacuum environments. Additionally, the high reactivity of the Se nanopowder with the transition metal coating in the conditions prevailing in the contact interface yields highly reproducible results, making it particularly suitable for the replenishment of sliding components with solid lubricants, avoiding the long‐lasting problem of TMD‐lubricity degradation caused by environmental molecules. The suggested straightforward approach demonstrates an unconventional and smart way to synthesize TMDs in operando and exploit their friction‐ and wear‐reducing impact.

AbstractPerovskite light‐emitting diodes (PeLEDs) are strong candidates for next‐generation display and lighting technologies due to their high color purity and low‐cost solution‐processed fabrication. However, PeLEDs are not superior to commercial organic light‐emitting diodes (OLEDs) in efficiency, as some key parameters affecting their efficiency, such as the charge carrier transport and light outcoupling efficiency, are usually overlooked and not well optimized. Here, ultrahigh‐efficiency green PeLEDs are reported with quantum efficiencies surpassing a milestone of 30% by regulating the charge carrier transport and near‐field light distribution to reduce electron leakage and achieve a high light outcoupling efficiency of 41.82%. Ni0.9Mg0.1Ox films are applied with a high refractive index and increased hole carrier mobility as the hole injection layer to balance the charge carrier injection and insert the polyethylene glycol layer between the hole transport layer and the perovskite emissive layer to block the electron leakage and reduce the photon loss. Therefore, with the modified structure, the state‐of‐the‐art green PeLEDs achieve a world record external quantum efficiency of 30.84% (average =  29.05 ± 0.77%) at a luminance of 6514 cd m−2. This study provides an interesting idea to construct super high‐efficiency PeLEDs by balancing the electron‐hole recombination and enhancing the light outcoupling.

AbstractMoS2 nanoribbons have attracted increased interest due to their properties, which can be tailored by tuning their dimensions. Herein, the growth of MoS2 nanoribbons and triangular crystals formed by the reaction between films of MoOx (2<x<3) grown by pulsed laser deposition and NaF in a sulfur‐rich environment is demonstrated. The nanoribbons can reach up to 10 µm in length, and feature single‐layer edges, forming a monolayer–multilayer junction enabled by the lateral modulation in thickness. The single‐layer edges show a pronounced second harmonic generation due to the symmetry breaking, in contrast to the centrosymmetric multilayer structure, which is unsusceptible to the second‐order nonlinear process. A splitting of the Raman spectra is observed in MoS2 nanoribbons arising from distinct contributions from the single–layer edges and multilayer core. Nanoscale imaging reveals a blue‐shifted exciton emission of the monolayer edge compared to the isolated MoS2 monolayers due to built‐in local strain and disorder. We further report on an ultrasensitive photodetector made of a single MoS2 nanoribbon with a responsivity of 8.72 × 102 A W−1 at 532 nm, among the highest reported up‐to‐date for single‐nanoribbon photodetectors. These findings can inspire the design of MoS2 semiconductors with tunable geometries for efficient optoelectronic devices.

AbstractThere is a need for rapid, sensitive, specific, and low‐cost virus sensors. Recent work has demonstrated that organic electrochemical transistors (OECTs) can detect the severe acute respiratory syndrome coronavirus 2 (SARS‐CoV‐2) spike protein. Here, a simple and low‐cost approach to the fabrication of OECT devices with excellent stability and unprecedented sensitivity and specificity for the detection of SARS‐CoV‐2 virus is demonstrated. The devices rely on the engineered protein minibinder LCB1, which binds strongly to SARS‐CoV‐2. The resulting devices exhibit excellent sensitivity for the detection of SARS‐CoV‐2 virus and SARS‐CoV‐2 spike protein receptor binding domain (RBD). These results demonstrate a simple, effective, and low‐cost biomolecular sensor applicable to the real‐time detection of SARS‐CoV‐2 virus and a general strategy for OECT device design that can be applied for the detection of other pathogenic viruses.
Elucidating Improvements to MIL‐101(Cr)’s Porosity and Particle Size Distributions based on Innovations and Fine‐Tuning in Synthesis Procedures
Authors: Wee Mei Gui Vanessa , Chinnappan Amutha , Ramakrishna Seeram 
Published: May 2023

AbstractAmong the existing metal–organic frameworks (MOFs), MIL‐101(Cr) is renowned for its stability in air and water. As a result, MIL‐101(Cr) has numerous potential applications ranging from adsorptive cooling to catalysis. The industrial‐scale production of MIL‐101(Cr) is necessary before realizing these applications. Yet, there remain two main bottlenecks in preparing MIL‐101(Cr) in bulk: the toxicity of hydrofluoric acid (HF) used in conventional MIL‐101(Cr) synthesis and the challenge of ensuring that the as‐prepared MIL‐101(Cr) is highly porous with specific Brunauer–Emmett–Teller surface area (SBET) above 4000 m2 g−1. On the laboratory scale, MIL‐101(Cr) often presents SBET 2300–3500 m2 g−1. The synthesis and purification procedures often influence the yield, particle size, porosity, and other properties of MIL‐101(Cr). This critical review examines trends in MIL‐101(Cr) preparation procedures and the MOF's resulting properties to elucidate areas for improvement toward its real‐world applications. The purification processes for conventional HF‐based MIL‐101(Cr) whereby porosities vary despite the same synthesis approach are first investigated. Next, the reported additives for substituting HF and their influence on the resulting MIL‐101(Cr)’s porosity and particle size are discussed. The selection of additives may be application‐specific: exemplified in the examination of MIL‐101(Cr)’s preparation, its corresponding water sorption capacity, and desiccant‐related applications.
