« Elles sont si peu que nous ne les voyons pas. » Les femmes et la prison dans les reportages de La Vie en rose
Authors: Biron Charlotte 
Published: April 2023

Cette étude porte sur un dossier intitulé « Les femmes en prison » paru en 1983 dans La Vie en rose et plus précisément sur les grands reportages écrits par Lise Moisan, Francine Pelletier et Françoise Guénette. L’analyse met en lumière la relation entre l’écriture du reportage au féminin et la représentation des femmes en prison. À travers l’examen de ces articles, il s’agira, d’une part, de se demander comment les journalistes de la revue féministe se réapproprient le reportage, genre journalistique qu’elles critiquent dès leur premier numéro. Il s’agira, d’autre part, de mesurer comment l’image des femmes en prison dans la revue se distingue du stéréotype de la femme criminelle, figure exceptionnelle surreprésentée dans l’espace médiatique, mais aussi de celui des femmes en prison dans les grands journaux d’information. Le dossier offre en effet une représentation singulière des femmes et du monde pénitentiaire. Le parallèle entre les reportages dans La Vie en rose et les discours sur les femmes en prison vise ainsi à explorer la façon dont les reporters préconisent une écriture de terrain qui met à distance un certain nombre d’idées reçues à travers une poétique féministe du reportage.
Collecting Race-Based Data in Health Research: A Critical Analysis of the Ongoing Challenges and Next Steps for Canada
Authors: Sheikh Fatima , Fox-Robichaud Alison E. , Schwartz Lisa 
Published: April 2023

The COVID-19 pandemic has had a global effect. The disproportionate impact on Indigenous peoples and racialized groups has brought ethical challenges to the forefront in research and clinical practice. In Canada, the Tri-Council Policy Statement (TCPS2), and specifically the principle of justice, emphasizes additional care for individuals “whose circumstances make them vulnerable”, including Indigenous and racialized communities. In the absence of race-based data to measure and inform health research and clinical practice, we run the risk of causing more harm and contributing to ongoing injustices. However, without an accepted framework for collecting, maintaining, and reporting race-based data in Canada, more guidance is needed on how to do this well. Importantly, a framework for collecting race-based data should build on existing guidance from Indigenous and other structurally marginalized communities, the TCPS2, recommendations from the World Health Organization, and involve relevant stakeholders. In this paper, we describe historical examples of unethical studies on Indigenous and racialized groups, discuss the challenges and potential benefits of collecting race-based data, and conclude with objectives for a pan-Canadian framework to inform how race-based data is collected, stored, and accessed in health research.

AbstractNanoelectromechanical systems (NEMS) of 2D nanomaterials are potent exploration devices for high‐sensitive mechanical coupling, mass testing, and biosensing. Nevertheless, the internal interference from the multiple resonant states easily causes the deviation and overlap of the target signal. Here, an oxidized‐MXene resonant system performs the unique response peak at the fundamental frequency f0,1 of 3.37 ± 0.04 MHz within the ultrawide frequency up to 400 MHz, due to the ferroelectric‐conductive structure. This unique resonant peak can effectively avoid the dispute of indistinguishable vibratal states. The resonator exhibits advanced performances with a large dynamic range of 70.41 ± 0.15 dB and low thermomechanical motion spectral density of . The molecular sensing mechanisms of the oxidized‐MXene system are systematically studied to achieve repeatable detection with high mass resolution (low to 8.00 ± 0.01 × 10‐19 g). These consequences can afford potential guidelines for the NEMS devices in terms of the credible and legible sensors for ultra‐accurate and interference‐free measurements.

Published: April 2023

AbstractSelf‐assembly of lead halide perovskite nanocrystals (NCs) into close‐packed, long‐range‐ordered nanostructures can effectively modulate their photoelectronic properties, yet significantly challenging. Herein, an efficient approach is reported to induce the hierarchical self‐assembly of perovskite CsPbBr3 NCs by phase transition using chiral cysteine ligands, yielding asymmetric Cs4PbBr6 nanorods (NRs) with the circularly polarized luminescent response. An interfacial phase transition process is found during the conversion of CsPbBr3 nanocubes to Cs4PbBr6 NCs initiated by cysteine molecules. Then the Cs4PbBr6 NCs aggregate sequentially to form nanoclusters, which further self‐assemble into the chiral Cs4PbBr6 NRs. Molecular dynamics simulations reveal that the Cs4PbBr6 nanochains gradually approach each other to achieve an asymmetric structure, and the simulated circular dichroism spectrum further supports the formation of a chiral structure. This work offers a facile method for the hierarchical chiral self‐assembly of lead halide perovskite nanostructures, which brings new insights to explore chiral nanostructures by modulating the surface chemistry and post self‐assembly.

AbstractStretchable ultra‐narrow (e.g., 10 µm in width) microelectrodes are crucial for the electrophysiological monitoring of single cells providing the fundamental understanding to the working mechanism of neuro network or other electrically functional cells. Current fabrication strategies either focus on the preparation of normal stretchable electrodes with hundreds of micrometers or millimeters in width by using inorganic conductive materials or develop conductive organic polymer gel for ultra‐narrow electrodes which suffer from low stretchability and instability for long‐term implantation, therefore, it is still highly desirable to explore bio‐interfacial ultra‐narrow stretchable inorganic electrodes. Herein, a hybrid strategy is reported to prepare ultra‐narrow multi‐channel stretchable microelectrodes without using photolithography or laser‐assisting etching. A 10 µm × 10 µm monitoring window is fabricated with enhanced interfacial impedance by the special rough surface. The stretchability achieves to 120% for this 10 µm‐width stretchable electrode. Supported by these superior properties, it is demonstrated that the stretchable microelectrodes can detect electrophysiological signals of single cells in vitro and collect electrophysiological signals more precisely in vivo. The reported strategy will open up the accessible preparation of the fine‐size stretchable microelectrode. It will significantly improve the resolution of monitoring and stimulation of inorganic stretchable electrodes.

AbstractPeripheral halogen regulations can endow non‐fullerene acceptors (NFAs) with enhanced features as organic semi‐conductors and further boost efficient organic solar cells (OSCs). Herein, based on a remarkable molecular platform of CH14 with more than six halogenation positions, a preferred NFA of CH23 is constructed by synergetic halogen swapping on both central and end units, rendering the overall enlarged molecular dipole moment, packing density and thus relative dielectric constant. Consequently, the CH23‐based binary OSC reaches an excellent efficiency of 18.77% due to its improved charge transfer/transport dynamics, much better than that of 17.81% for the control OSC of CH14. This work demonstrates the great potential for further achieving state‐of‐the‐art OSCs by delicately regulating the halogen formula on these newly explored CH‐series NFAs.

AbstractHomogenous radioactive gas contamination constitutes the hardest challenge for radioprotection due to its elusive nature. Most common radioactive gas are 85Kr, 222Rn, and tritiated (3H) vapors. Each of them has different challenges, often leading to specialized single‐gas detectors. The state‐of‐the‐art detection either produces chemical‐radiological waste, is hard to implement online, or requires large volume. A new paradigm is presented for radioactive gas detection that can perform online detection on any gas and fit in the hand. This study use photoluminescent metal organic frameworks (MOFs) as both porous gas sponges and scintillators. The response of several zinc based MOF is studied, using a unique radioactive gas test bench. These tests showed that MOFs are able to both concentrate and detect successfully 85Kr. The investigation is completed with calibration with different activities. The study also reports detection of 222Rn, and measurement of its half‐life. Finally, the study is completed with the successful detection of tritiated dihydrogen, commonly known to be a hard radionuclide to detect due to its low energy and penetration range. This paper shows that scintillating MOFs are a powerful solid‐state approach and a practical solution to the challenge of radioactive gas measurements.

Published: April 2023

AbstractHierarchical carbon nanocages as emerging nanomaterials have a great potential for photothermal therapy due to their unique porous structure, high specific surface area, and excellent photothermal property. Herein, a hierarchical nitrogen‐doped carbon nanocage (hNCNC) is introduced as a second near‐infrared photothermal agent, and then functionalizes it with metal‐organic hydrogel (MOG) to form a thermal‐responsive switch for sensitized photothermal therapy. Upon 1064 nm light irradiation, the hNCNCs exhibit a remarkable photothermal conversion efficiency of 65.9% owing to a high near‐infrared extinction coefficient. Meanwhile, due to the hierarchical structure, hNCNCs show 60.2% (wt./wt.) loading efficiency of quercetin, a heat shock protein (Hsp70) inhibitor. Through thermal‐driven dry‐gel transformation, the coating MOGs intelligently release the encapsulated quercetin for sensitizing cancer cells to heat. Based on the synergistic effect of hyperthermia elevation and thermal‐driven drug release, the dual thermal utilization platform achieves effective photothermal tumor ablation in vivo under low concentration of hNCNCs and mild irradiation, which provides a new diagram of intelligent responsive photothermal agents for enhanced photothermal therapy.

Published: April 2023

AbstractPolysulfides aqueous redox flow batteries (PS‐ARFBs) with large theoretical capacity and low cost are one of the most promising solutions for large‐scale energy storage technology. However, sluggish electrochemical redox kinetics and nonnegligible crossover of aqueous polysulfides restrict the battery performances. Herein, it is found that the Co, Zn dual‐doped N‐C complex have enhanced electrochemical adsorption behaviors for Na2S2. It exhibits significantly electrochemical redox activity compared to the bare glassy carbon electrode. And the redox reversibility is also improved from ΔV = 210 mV on Zn‐doped N‐C complex to ΔV = 164 mV on Co, Zn‐doped N‐C complex. Furthermore, membrane‐electrode assembly (MEA) based on Co, Zn‐doped N‐C complex is firstly proposed to enhance the redox performances and relieve the crossover in PS‐ARFBs. Thus, an impressively high and reversible capacity of 157.5 Ah L−1 for Na2S2 with a high capacity utilization of 97.9% could be achieved. Moreover, a full cell PS‐ARFB with Na2S2 anolyte and Na4[Fe(CN)6] catholyte exhibits high energy efficiency ≈88.4% at 10 mA cm−2. A very low capacity decay rate of 0.0025% per cycle is also achieved at 60 mA cm−2 over 200 cycles.

AbstractAimSurgical site infection (SSI) is one of the most common postoperative complications in gastrointestinal surgery. To clarify the superiority of 1.5% olanexidine, we conducted a randomized prospective clinical trial that enrolled patients undergoing gastrointestinal surgery with operative wound classes II–IV.MethodsTo evaluate the efficacy of 1.5% olanexidine in preventing SSIs relative to 10% povidone‐iodine, we enrolled 298 patients in each group. The primary outcome was a 30‐day SSI, and the secondary outcomes were incidences of superficial and deep incisional SSI and organ/space SSI. In addition, subgroup analyses were performed.ResultsThe primary outcome of the overall 30‐day SSI occurred in 38 cases (12.8%) in the 1.5% olanexidine group and in 53 cases (18.0%) in the 10% povidone‐iodine group (adjusted risk ratio: 0.716, 95% confidence interval: 0.495–1.057, p = 0.083). Organ/space SSI occurred in 18 cases (6.1%) in the 1.5% olanexidine group and in 31 cases (10.5%) in the 10% povidone‐iodine group, with a significant difference (adjusted risk ratio: 0.587, 95% confidence interval: 0.336–0.992, p = 0.049). Subgroup analyses revealed that SSI incidences were comparable in scheduled surgery (relative risk: 0.809, 95% confidence interval: 0.522–1.254) and operative wound class II (relative risk: 0.756, 95% confidence interval: 0.494–1.449) in 1.5% olanexidine group.ConclusionOur study revealed that 1.5% olanexidine reduced the 30‐day overall SSI; however, the result was not significant. Organ/space SSI significantly decreased in the 1.5% olanexidine group. Our results indicate that 1.5% olanexidine has the potential to prevent SSI on behalf of povidone‐iodine.

AbstractVenous thromboembolism (VTE) is a significant complication for cancer patients undergoing systemic therapy. We performed an independent external validation for a recently derived and validated a novel electronic health record (EHR) VTE risk score in a comprehensive cancer center. Adult patients with incident cancer diagnoses were identified from MD Anderson Cancer Center Tumor Registry 1/2017–1/2021. Baseline covariates extracted at the time of first‐line systemic therapy included demographics, cancer site/histology, stage, treatment, complete blood count, body mass index, recent prolonged hospitalization, and history of VTE or paralysis. VTE was ascertained using an institution‐specific natural language processing radiology algorithm (positive predictive value of 94.8%). The median follow‐up for 21 142 cancer patients was 8.1 months. There were 1067 (5.7%) VTE within 6 months after systemic therapy. The distribution of the novel score for 0‐, 1, 2, 3, 4, 5+ was 5661, 3558, 3462, 3489, 2918, and 2054; while the corresponding 6‐month VTE incidence was 1.3%, 3.1%, 5.4%, 7.3%, 9.3%, and 13.8%, respectively (c statistic 0.71 [95% CI 0.69–0.72] with excellent calibration). In comparison, the Khorana score had a c statistic of 0.64 [95% CI 0.62–0.65]. The two risk scores had 80% concordance; the novel score reclassified 20% of Khorana score (3530 low‐to‐high with 9.0% VTE; 734 high‐to‐low with 3.4% VTE) and led to a 25% increment in VTEs captured in the high‐risk group. In conclusion, the novel score demonstrated consistent discrimination and calibration across cohorts with heterogenous demographics. It could become a new standard to select high‐risk populations for clinical trials and VTE monitoring.

AbstractWährend die meisten Ansätze zur Analyse von geringen Probemengen durch Nanoproteomik auf der bottom‐up‐Strategie basieren, sind top‐down‐Ansätze zur Charakterisierung von Proteoformen nach wie vor unterrepräsentiert. An Proteomen von Säugerzellen haben wir eine einfache Probenvorbereitungsmethode etabliert, welche auf Proteinaggregation an magnetischen Partikeln und anschließender Elution intakter Proteoformen durch 40 %ige Ameisensäure basiert. Die Implementierung der Methode auf einer Plattform für digitale Mikrofluidik ermöglichte die sensitive Analyse von einzelnen Individuen des Nematoden Caenorhabditis elegans. Die Anzahl identifizierter Proteoformen konnte dabei im Vergleich zu herkömmlicher Probenvorbereitung in einem Reaktionsgefäß um 46 % erhöht werden. Ferner erlaubte die markierungsfreie (label‐free) Quantifizierung von Proteomen einzelner Nematoden, welche unter verschiedenen Bedingungen kultiviert wurden, Änderungen der Abundanz von Proteoformen zu erkennen, welche in bottom‐up‐Experimenten nicht festgestellt wurden. Die hier präsentierte Methode wird die Proteoform‐zentrische Analytik in Proben mit limitierter Verfügbarkeit vereinfachen.
Catalytic SNAr Hexafluoroisopropoxylation of Aryl Chlorides and Bromides
Authors: Su Jiang , Chen Kai , Kang Qi‐Kai , Shi Hang 
Published: April 2023

AbstractFluoroalkyl aryl ethers are valuable structural motifs in pharmaceuticals because compounds with these motifs are more metabolically stable and more lipophilic than their nonfluorinated analogues. However, hexafluoroisopropyl aryl ethers have not been extensively studied, presumably because of the lack of efficient synthetic methods. Herein, we describe a rhodium‐catalyzed nucleophilic aromatic substitution of aryl chlorides or bromides, which act as the limiting reagents, with weakly nucleophilic hexafluoro‐2‐propanol under mild reaction conditions. This method provides diverse hexafluoroisopropyl aryl ethers. We demonstrated the generality of this method by carrying out reactions of a large array of unactivated aryl halides, and we found that the success of the reactions relied on arene activation by means of η6‐coordination.

Published: April 2023

AbstractPerovskite solar cells (PSCs) based on SnO2 electron transport layers have attracted extensive research due to their compelling photovoltaic performance. Herein, we presented an in situ passivation of SnO2 with low‐cost hydroxyacid potassium synergist during deposition to optimize the interface carrier extraction and transport for high power conversion efficiency (PCE) and stabilities of PSCs. The orbital overlap of the carboxyl oxygen with the Sn atom alongwith the homogenous nano‐particle deposition effectively suppresses the interfacial defects and releases the internal residual strains in the perovskite. Accordingly, a PCE of 24.91 % with a fill factor (FF) up to 0.852 is obtained for in situ passivated devices, which is one of the highest values for SnO2‐based PSCs. Moreover, the unencapsulated device maintained 80 % of its initial PCE at 80 °C over 600 h, 100 % PCE at ambient conditions for 1300 h, and 98 % after one week maximum power point tracking (MPPT) under continuous AM1.5G illumination.
Enhancing the thermoplastic behavior and mechanical performance of recycledHDPE/CaCO3composites using oxidized polyethylene
Authors: Ghosh Arun 
Published: April 2023

AbstractThere is a growing interest in sustainable materials based on recycled or natural feedstocks for the circular economy. Ideally, thermoplastic materials are anticipated to show appropriate melt‐flow behavior for thermo‐mechanical recycling, good melt stability, and mechanical performance. Thermoplastic polyolefins such as polyethylenes are used as single‐use packaging materials and generate environmental concerns. This article reports the melt‐processing and characterization of composite materials based on recycled high‐density polyethylene (rHDPE) and naturally abundant calcium carbonate (CaCO3) mineral at various mass ratios such as 70/30, 50/50, and 30/70. Oxidized polyethylene (OPE) is used as an additive, with 20 wt% replacement of rHDPE, to improve the materials' mechanical performance and thermoplastic behavior. Various characteristics such as tensile, viscoelastic, melt‐flow, phase morphology, and thermomechanical recyclability of the materials are analyzed. It reveals that composites with high CaCO3content compatibilized with OPE show improved tensile strength and modulus. For example, the composite based on 10/70/20 (wt%) of rHDPE/CaCO3/OPE shows an average tensile strength of 27.4 MPa and Young's modulus of 4.5 GPa, in contrast to the rHDPE sample, which shows an average tensile strength of 12.4 MPa and Young's modulus of 967 MPa. Notably, adding OPE decreases the melt‐viscosity of the rHDPE/CaCO3materials, thus improving the composites' melt‐flow and thermoplastic behavior. This study indicates the possibility of developing natural CaCO3‐rich polymer composites with thermoplastic behavior for real‐life applications with superior mechanical and melt‐flow properties suitable for thermomechanical recycling.
