Published: February 2019

ABSTRACT
An exploration of the effect of epoxidized NR with 50 mole% epoxide groups (ENR-50) as compatibilizer on the rubber–filler interaction of microcrystalline cellulose (MCC)-filled NR composites was conducted. The compatibilizing efficiency of ENR-50 was systematically examined in terms of cure and mechanical and thermal properties of NR/MCC composites. ENR-50 compatibilized NR/MCC composites showed moderate enhancement in the maximum rheometric torque and tensile properties compared to either uncompatibilized NR/MCC composite or unfilled NR system. The solvent uptake measurements indicated improved interfacial interaction between NR matrix and MCC in presence of ENR-50 as compatibilizer. A thermogravimetric analysis confirmed excellent improvement in the thermal stability of NR/MCC composite in the presence of ENR-50 as compatibilizer. Fourier transform infrared spectroscopy was used to explain the probable mechanism of interaction between NR matrix and MCC in the presence of ENR-50.

Published: February 2019

Apesar da importância crescente de outras fontes energéticas ao longo das últimas décadas, como das chamadas “fontes renováveis”, o petróleo se manteve como principal fonte da matriz energética mundial. Diante do papel desempenhando por essa commodity para a economia mundial, este trabalho buscou averiguar os principais elementos desencadeadores das oscilações no preço do barril do petróleo, com o objetivo de abrir a caixa preta do contrachoque que ocorreu a partir de 2014. A metodologia adotada se apoiou em análise bibliográfica, pesquisa documental e coleta de dados secundários. A principal conclusão que se extrai deste estudo é a de que o preço do petróleo oscila em função de três variáveis fundamentais, quais sejam: oferta versus demanda, questões geopolíticas e mercado financeiro. A oscilação no sistema de preços do barril de petróleo é influenciada por estes fatores ao mesmo tempo em que os influencia em um processo de retroalimentação. Nesse sentido, estudos apoiados exclusivamente nos movimentos do mercado (isto é, em flutuações na oferta e na demanda) são insuficientes para explicar os choques e contrachoques no preço do petróleo.

Voyage et publicité dans les Murray’s Handbooks for Travellers
Authors: Dziub Nikol 
Published: February 2019

Le propos de cet article est d’analyser la façon dont l’entreprise éditoriale des Murray’s Handbooks for Travellers a contribué à la modification de la perception culturelle du monde et du voyage en proposant un produit livresque répondant aux attentes des tour-istes. Du premier Handbookfor Travellers on the Continent (1836) jusqu’à la huitième édition du Handbook for Travellers in India, Burma, and Ceylon (1911), nous nous proposons d’étudier le discours publicitaire qui se développe dans les guides Murray, en nous concentrant notamment sur l’Advertiser qui figure dans la majorité de ces ouvrages à la couverture rouge et publiés in a pocket volume – l’Advertiser, en général, étant loin d’être exclusivement consacré au pays dont parle le Handbook. Les Handbooks de Murray font du (guide de) voyage lui-même un produit semblable à ceux dont l’Advertiser fait la publicité : il s’agira donc pour nous de montrer en quoi ce nouveau support change la nature même du voyage.
Arriver dans la colonie : distance et littérature. Variations autour d’un motif sous la Troisième République, du journal au livre
Authors: Demougin Laure 
Published: February 2019

Quelles sont les modalités qui permettent au lectorat de l’époque coloniale d’entrer, littérairement parlant, dans l’empire colonial français? Sous la Troisième République, la question est importante pour des raisons politiques et idéologiques : on verra ici, à travers trois cas particuliers, comment les entrées dans les textes engagent différemment l’expérience d’une lecture exotique. Comparer ces premières lignes issues du livre ou des périodiques permet de mettre en évidence les variations de l’aventure coloniale et de sa modernité par le biais de la vitesse narrative : un récit de voyage, un roman d’aventure de Jules Verne et un reportage d’Albert Londres trouveront ainsi des points communs qui éclairent l’entreprise coloniale. Selon que les récits ont été publiés dans des journaux ou dans des livres, la vitesse de lecture n’est pas la même, le support jouant un rôle considérable dans la perception de l’aventure elle-même.
Le roman de la ligne
Authors: Carrier-Lafleur Thomas 
Published: February 2019

À travers l’analyse de trois romans appartenant à la première période de l’oeuvre du romancier, cet article traite d’un aspect central chez Jules Verne : la construction d’une ligne droite. Comme le notait Roland Barthes, Les voyages extraordinaires sont construits sur un désir d’habitation : il faut habiter la structure, la moduler, la faire sienne. La ligne droite constitue la structure de prédilection des personnages verniens. C’est par elle que naîtra l’aventure et que la modernité prendra toute son expansion. Dans cet article, nous tenterons ainsi de suivre la ligne droite jusque dans ses extrêmes limites, pour voir les autres structures qu’elle permet d’imaginer et les autres mondes qu’elle permet d’explorer.
« J’en suis venu à accepter aussi bien l’autorité des récits et celle des articles »
Authors: Letourneux Matthieu 
Published: February 2019

Dans les pulps américains, les imaginaires sériels débordent l’espace de la fiction pour contaminer la partie rédactionnelle du magazine. Le pulp Adventure, spécialisé dans les récits d’aventures, illustre cette circulation des imaginaires. À travers des rubriques comme « The Camp-Fire » et « Ask Adventure », il invite les consommateurs à échanger avec auteurs et spécialistes, créant une communauté de lecteurs liés entre autres par des projets tout droit sortis de récits d’aventures et manifestant une forme de fictionnalisation de l’existence. Or, dans ces fantasmes d’accomplissement romanesque peut se lire une reformulation du rêve pionnier, au moment même où celui-ci s’efface aux États-Unis pour laisser place à de nouveaux modèles de réussite sociale. À partir de cet exemple, nous voudrions montrer plus largement que, dans leur façon de structurer les imaginaires et de les associer à des formes identifiables, les genres permettent d’interroger la manière dont une culture donnée organise en systèmes de signification et à travers des modèles récurrents de narration certaines des préoccupations d’une collectivité.
Les voyages du Journal de l’Atlantique. Circulations, attachements et modernité
Authors: Langonné Joël 
Published: February 2019

LeJournal de l’Atlantiqueest un quotidien distribué dès 1906 sur les paquebots de la Compagnie Générale Transatlantique (CGT). Sa ligne éditoriale épouse des lignes maritimes. Ces deux entités conjuguent leurs imaginaires empreints de modernité, via une technique nouvelle de communication longue distance, la radiotélégraphie. Ainsi, leJournal de l’Atlantiqueest d’abord le réceptacle de relations composites avec des techniques relevant de matérialités et d’acteurs divers : à bord dessteamers, l’atelier de composition et l’imprimerie sont liés au radiotélégraphe, qui capte des nouvelles des deux continents. Il ouvre ensuite à une temporalité singulière, les lecteurs s’attachent au journal le temps d’une traversée et l’expérience est toujours « une autre première fois1 ». LeJournal de l’Atlantiqueest enfin un révélateur de voyages qui sont aussi matière à publicité et à consommation de masse. C’est en effet une filiale de la Compagnie Marconi qui édite leJournal de l’Atlantique: cette dernière vend ainsi des radiotélégraphes, des informations et des publicités pour distribuer, en fin de compte, un journal attachant parce qu’attaché à un imaginaire de la modernité fait de communications sans fil et ininterrompues avec le monde.

ImportanceOnline review platforms offer valuable insights into patient satisfaction and the quality of health care services, capturing content and trends that traditional metrics might miss. The COVID-19 pandemic has disrupted health care services, influencing patient experiences.ObjectiveTo examine health care facility numerical ratings and patient experience reported on an online platform by facility type and area demographic characteristics after the COVID-19 pandemic (ie, post-COVID).Design, Setting, and ParticipantsAll reviews of US health care facilities posted on one online platform from January 1, 2014, to December 31, 2023, were obtained for this cross-sectional study. Analyses focused on facilities providing essential health benefits, which are service categories that health insurance plans must cover under the Affordable Care Act. Facility zip code tabulation area level demographic data were obtained from US census and rural-urban commuting area codes.Main Outcomes and MeasuresThe primary outcome was the change in the percentage of positive reviews (defined as reviews with ≥4 of 5 stars) before and post-COVID. Secondary outcomes included the association between positive ratings and facility demographic characteristics (race and ethnicity and urbanicity), and thematic analysis of review content using latent Dirichlet allocation.ResultsA total of 1 445 706 reviews across 151 307 facilities were included. The percent of positive reviews decreased from 54.3% to 47.9% (P &amp;lt; .001) after March 2020. Rural areas, areas with a higher proportion of Black residents, and areas with a higher proportion of White residents experienced lower positive ratings post-COVID, while reviews in areas with a higher proportion of Hispanic residents were less negatively impacted (P &amp;lt; .001 for all comparisons). For example, logistic regression showed that rural areas had significantly lower odds of positive reviews post-COVID compared with urban areas (odds ratio, 0.77; 95% CI, 0.72-0.83). Latent Dirichlet allocation identified themes such as billing issues, poor customer service, and insurance handling that increased post-COVID among certain communities. For instance, areas with a higher proportion of Black residents and areas with a higher proportion of Hispanic residents reported increases in insurance and billing issues, while areas with a higher proportion of White residents reported increases in wait time among negative reviews.Conclusions and RelevanceThis serial cross-sectional study observed a significant decrease in positive reviews for health care facilities post-COVID. These findings underscore a disparity in patient experience, particularly in rural areas and areas with the highest proportions of Black and White residents.

AbstractThe development of rechargeable lithium batteries (RLBs) has made a great contribution in solving the problems in the current era, such as energy shortage and climate change. With the expanding of application field of RLBs from portable device to large‐scale electric equipment, it is an urgent demand for RLBs to operate in a wide range of temperature. More and more attention has been paid to the design of wide‐temperature RLBs. Therefore, a timely and critical overview of the latest development in the field of RLBs operating at wide temperatures is needed. In this review, an in‐depth understanding on how the temperature affects the thermodynamics of lithium‐ion transport at electrodes, electrolytes, and electrode/electrolyte interfaces is emphasized. Recent progress in probing the temperature effects on electrochemical performance fading is comprehensively discussed. Different strategies to widen the working temperature of RLBs, including regulating the electrode degradation, interface evolution, and electrolyte solvation chemistry are also reviewed. Finally, an outlook of potential future research directions is also proposed, which sheds light on the design of novel electrodes and electrolytes for next‐generation RLBs operating at wide temperatures.

AbstractExtracting uranium from the ocean is considered a promising solution for meeting nuclear fuel consumption. To date, porous adsorbents fabricated with polyamidoxime (PAO), particularly macroporous PAO hydrogels, have demonstrated exceptional potential for uranium capture from natural seawater. Herein, a novel macroporous PAO hydrogel is developed via a well‐designed wax‐casting method. The developed wax‐casted macroporous PAO (WMPAO) hydrogel particles are subsequently encapsulated in alginate‐polyacrylic acid (A‐PAA) beads. The obtained A‐PAA@WMPAO beads exhibit a high qmax of 687.4 mg‐U/g‐Ads. and show a good adsorption capacity of 8.23 mg g−1 toward uranium in simulated seawater. Additionally, A‐PAA@WMPAO shows good reusability with a 31.2% reduction in uranium adsorption capacity after five consecutive adsorption‐desorption cycles. Furthermore, A‐PAA@WMPAO displays satisfactory extraction efficiencies of 95.9–99.5% for U‐spiked coastal seawater after 10 days of adsorption, achieving adsorption capacities ranging from 207.5 to 3963.2 µg g−1. Particularly, with the utilization of 4 mg of A‐PAA@WMPAO beads, a high adsorption capacity of 4.79 mg g−1 for uranium from 10 L of coastal seawater within 15 days is achieved. These obtained results comprehensively demonstrate the significant potential of the fabricated A‐PAA@WMPAO beads for uranium capture from natural seawater.

AbstractIn embedded 3D printing, the supporting gel must provide the right rheological properties to keep the ink in place. It has previously been shown that a strong and stable 3D network can be formed by particle–particle interactions of hydrophobic fumed silicas suspended in a polar solvent. Here, the rheological properties of fumed silica gels in polyethylene glycol (PEG) are investigated. The recovery properties like storage modulus, yield stress, and recovery time of the gels made of fumed silica with alkyl‐chains of different lengths are studied. A very fast recovery time (0.2 s) is achieved by increasing the length of the alkyl chains on the silica surface, leading to embedded printing results with high shape accuracy. However, with the engineered supporting gel, the formation of crevasses affects the shape of the filament. Previous approaches to reduce crevasse formation include the introduction of liquid fillers to avoid such distortions, which, however, prevents the reuse of the gels and leads to increasing waste production in embedded printing. Here, it is shown that by adjusting the rheology of the inks to fit the rheology of the supporting gel, high‐shape accuracy prints with ideally round‐shaped filaments can be achieved without the need for liquid fillers.

Authors: Seong Jihun , Lee Ju‐Hee , Han Min‐Woo 
Published: November 2024

AbstractIn fields such as wearable technology and soft robotics, sensors that detect bending and pressure using flexible materials are becoming essential. This study aims to develop textile sensors using stitching methods with conductive yarn. Four types of sensors introduced: tensile and tactile sensors with rubber bands, flex sensors with films, and volumetric sensors with balloons. High sewing density and multi‐layer design improve performance. Experiments reveale a gauge factor (GF) of 1.52 for the multi‐layered tensile sensor under 11% strain, indicating a 20% improvement over single‐layer sensors. Flex sensors effectively detect resistance changes due to curvature, varying with bending velocity. Volumetric sensors demonstrate their adaptability in many shapes and materials with response times under 1 s. There is significant potential for these flexible and adaptable soft sensors in the healthcare and medical industries, especially due to their easy integration with wearable devices.

AbstractThermal management is crucial in advanced wearable electronics, especially those with high integration and miniaturization, or incorporating self‐powered systems utilizing body heat. However, the low thermal conductivity of traditional silicone rubber encapsulation presents a major challenge to thermal management in wearable electronics. In this study, hexagonal boron nitride@Eutectic Gallium‐Indium/Ecoflex (h‐BN@EGaIn/Ecoflex) composites, a soft elastic material is developed that is thermally conductive yet electrically insulating, capable of serving as encapsulation and thermal interface materials in wearable devices. The key of successfully designing h‐BN@EGaIn/Ecoflex composites with such thermal, mechanical, and electrical properties is the anchoring of EGaIn on the h‐BN surface. Also, there exists a trade‐off in thermal‐electrical and thermal‐mechanical properties of the composites during the preparation of h‐BN@EGaIn hybrid fillers and their incorporation into the Ecoflex elastomer. In application demonstrations, through replacing the polydimethylsiloxane supporting layer with h‐BN@EGaIn/Ecoflex composites, a 20 K operation temperature decrease is observed in a wearable light‐emitting diode lamp. In addition, the output of a wearable thermoelectric generator encapsulated with h‐BN@EGaIn/Ecoflex composites increases by 100% compared to that encapsulated by Ecoflex. These results clearly show the benefits of substituting h‐BN@EGaIn/Ecoflex for silicon rubber encapsulation in wearable electronics.

AbstractWith the widespread application of batteries in modern society, ensuring their safety and performance has become crucial. Traditional diagnostic methods, while providing valuable insights into battery performance, often require destructive sampling, making it difficult to achieve non‐destructive and real‐time monitoring. As a result, magnetic field‐based non‐destructive testing techniques, such as nuclear magnetic resonance (NMR), magnetic resonance imaging (MRI), and magnetic field imaging (MFI), have emerged as powerful tools for battery diagnostics. These techniques have garnered significant attention due to their non‐invasive nature and real‐time detection capabilities, allowing for the identification of defects and malfunctions under normal operating conditions without disassembling the battery or interrupting its use. This paper reviews recent advancements in the application of magnetic field‐based non‐destructive testing technologies for battery diagnostics, analyzing both their strengths and limitations. Through a comprehensive assessment of current research findings, this work provides researchers and engineers with a systematic reference to promote the application and development of magnetic field technologies in the battery field. Additionally, this review discusses the challenges and limitations encountered by magnetic field technologies in battery diagnostics and provides recommendations for their future development. The objective is to offer insights and foster continued innovation and advancement in this field.

AbstractHigh‐energy density and long‐lifespan have been a long‐standing target toward the high‐voltage sodium batteries requirement. It is important and essential to explore cathode materials, which can realize high voltage stability. Large‐sized single‐crystal O3‐typed Na[Ni0.3Mn0.35Cu0.1Ti0.25]O2 is thus designed and successfully synthesized by molten salt‐assist calcination method. The high‐orientation crystal lattice without grain boundaries cannot only accelerate the ion diffusion rate and electronic conductivity, but also minimize the occurrence of phase transitions and mechanical stress to address the crystal oxygen loss. Meanwhile, the large‐exposed stable (003) crystal plane can alleviate the electrolyte attacking and corrosions, forming a stable interface structure. The obtained material exhibits capacity retention rates of 84.4% and 90.1% after 200 cycles at 0.5 C and 1 C, respectively. Once coupled with hard carbon as anode, the full‐cell retains a high 81.5% capacity retention after 1000 cycles at 2 C.
