The freight landscape: Convergence and divergence in urban freight distribution
Authors: Rodrigue Jean-Paul , Dablanc Laetitia , Giuliano Genevieve
Published: November 2017

The paper introduces the concept of the freight landscape: the spatial distribution of freight activity and intensity in a metropolitan area. Using population and employment density information, a freight landscape matrix is calculated for four major metropolitan areas: New York, Los Angeles, Paris and Seoul. Levels of convergence and divergence between population and employment densities are assessed, each characterized by different freight landscapes requiring different city logistics strategies. Results reveal substantial variations between metropolitan areas, which are observed across the respective levels of zonal specialization as well as density changes over distance from central areas.
What is mixed use? Presenting an interaction method for measuring land use mix
Authors: Manaugh Kevin , Kreider Tyler
Published: November 2017

In recent decades, the mixing of complementary land uses has become an increasingly important goal in transportation and land use planning. Land uses mix has been shown to be an influential factor in travel behavior (mode choice and distance traveled), improved health outcomes, and neighborhood-level quality of life. However, quantifying the extent to which a given area is mixed-use has proven difficult. Much of the existing research on the mixing of land uses has focused on the presence and proportion of different uses as opposed to the extent to which they actually interact with one another. This study proposes a new measure of land use mix, a land use interaction method—which accounts for the extent to which complementary land uses adjoin one another—using only basic land use data. After mapping and analyzing the results, several statistical models are built to show the relationship between this new measure and reported travel behavior. The models presented show the usefulness of the approach by significantly improving the model fit in comparison to a commonly-used land use mix index, while controlling for socio-demographic and built form factors in three large Canadian cities (Vancouver, Toronto, and Montreal). Our results suggest that simple, area-based, measures of land use mix do not adequately capture the subtleties of land use mix. The degree to which an area shows fine-grained patterns of land use is shown to be more highly correlated with behavior outcomes than indices based solely on the proportions of land use categories.
La presencia invisible de la mujer deportista en la prensa deportiva española. Análisis de las portadas de "Marca", "As", "Mundo Deportivo" y "Sport" (2010-2015
Authors: Gómez-Colell Eva , Medina-Bravo Pilar , Ramon Xavier
Published: November 2017

La realidad de las mujeres sigue siendo explicada por los medios de comunicación desde una perspectiva androcéntrica, a pesar de una mayor presencia femenina en la esfera pública. En el contexto del periodismo deportivo, la cobertura mediática de las deportistas es discreta, incluso nula. Cualitativamente, la información referida a las mujeres y a su actividad recurre de manera reiterada a los estereotipos de género. Ello se debe a que, tanto el deporte en sí como el periodismo deportivo, se han construido como un territorio predominantemente masculino, donde las desigualdades de género y los prejuicios sexistas se han legitimado. La presente investigación analiza las portadas de los cuatro diarios deportivos más leídos en España (Marca, As, Mundo Deportivo y Sport) durante un periodo de cinco años (2010-2015), los resultados de la cual reafirman que “el deporte continúa existiendo por, para y sobre los hombres” (Cooky et al., 2013: 205)
Plata o plomo: el crimen organizado como fuente de información periodística
Authors: González Macías Rubén Arnoldo
Published: November 2017

El objetivo de este artículo es explicar la influencia del crimen organizado en el proceso de producción de noticias, para lo cual se utilizó el concepto de Sistema del Discurso de Conflicto. El análisis apunta a que los cárteles, como fuentes de información, frecuentemente determinan la agenda y encuadre de los mensajes periodísticos sobre la “guerra al narco” en México; lo cual logran a través del uso del soborno o la violencia.
China tras la mirada de la televisión española
Authors: Rodríguez Wangüemert Carmen , Rodríguez Breijo Vanessa , Pestano Rodríguez José Manuel
Published: November 2017

La movilidad psíquica que proporcionan los medios permite disponer de una imagen de un país en el que no se ha estado o de una sociedad con la que no se mantiene relación directa. Esta imagen construida se asienta sobre intereses editoriales y simplificaciones productivas que responden a la posición que ocupa el país en relación a otros. En el caso de China se observa en la televisión cómo las informaciones políticas y económicas características de países desarrollados coexisten junto a contenidos sensacionalistas, más propios de los que se dedican a países de la periferia. El estatus mediático otorgado a China parece corresponder al de un país todavía en proceso de transición hacia el centro del contexto internacional
Análisis de las consecuencias de la crisis económica en el sector de la prensa: el caso del País Vasco
Authors: Maiza Larrarte Andoni , Genaut Arratibel Aingeru
Published: November 2017

En este artículo se evalúa el impacto de la crisis económica en el sector de la prensa y los medios informativos en la CAPV. Para ello, en primer lugar se presenta una definición ad-hoc del sector utilizando la Clasificación Nacional de Actividades Económicas (CNAE-2009), lo que permite emplear fuentes de información estadísticas poco utilizadas para analizar el sector y sirve para poner de relieve la especial incidencia de la crisis sobre los centros de trabajo de menor tamaño. En el estudio también se aborda el desigual efecto de la crisis sobre el negocio de las diferentes ramas de actividad (prensa, radio, TV y agencias de noticias), y se evidencia la heterogeneidad de un tejido empresarial regional en el que no hay presencia de grandes conglomerados multimedia
Los refugiados políticos y la traducción
Authors: Fernández Rodríguez Áurea
Published: November 2017

El objetivo general de nuestro análisis consiste en hacer patente la especificidad de los refugiados políticos gallegos desde la perspectiva de la traducción como práctica. Hacemos referencia a la actividad de algunos de los traductores gallegos, en su mayoría universitarios, escritores y humanistas que se marcaron el deber de luchar para mantener y recuperar el periodo de progreso cultural de la España republicana anterior a la Guerra Civil española. Al mismo tiempo conseguían introducir nuevos textos con los que potenciaban la cultura y la industria editorial en los países de acogida. A modo de ilustración nos detendremos en la actividad del refugiado político e historiador José Almoina de Mateos (1903-1960).
Screening for Infection Before Revision Hip Arthroplasty: A Meta-analysis of Likelihood Ratios of Erythrocyte Sedimentation Rate and Serum C-reactive Protein Levels
Authors: Huerfano Elina , Bautista Maria , Huerfano Manuel , Bonilla Guillermo , Llinas Adolfo
Published: November 2017

Introduction:

Diagnosing periprosthetic joint infection (PJI) before revision hip arthroplasty is critical to ensure effective treatment of patients undergoing surgery for reasons other than infection. The main objective of our study is to determine whether the erythrocyte sedimentation rate (ESR) and the serum C-reactive protein (CRP) level are sufficient to use for testing to rule out infection in patients undergoing revision hip surgery.

Methods:

We performed a systematic review of the literature in the MEDLINE, Ovid, and Embase databases. We included studies in which the investigators used the ESR (>30 mm/h) and serum CRP level (>10 mg/L) for the diagnosis of PJI of the hip. We obtained meta-estimates of sensitivity, specificity, positive likelihood ratio (LR+), and negative likelihood ratio (LR−).

Results:

From 511 articles, we analyzed 12 studies in which the investigators reported data on 2,736 patients. Sensitivity and specificity for the ESR were 0.860 (95% confidence interval [CI], 0.825 to 0.890) and 0.723 (95% CI, 0.704 to 0.742), respectively, and for the CRP level were 0.869 (95% CI, 0.835 to 0.899) and 0.786 (95% CI, 0.769 to 0.803), respectively. For the ESR, LR+ was 3.42 (95% CI, 2.55 to 4.59) and LR− was 0.22 (95% CI, 0.12 to 0.41). For the CRP level, LR+ was 4.18 (95% CI, 3.42 to 5.11) and LR− was 0.20 (95% CI, 0.12 to 0.32).

Discussion:

With a low pretest probability of PJI, a negative test result for either the ESR or CRP level is enough to rule out infection before revision hip arthroplasty.

Level of Evidence:

Complication Rates After Total Hip and Knee Arthroplasty in Patients With Hepatitis C Compared With Matched Control Patients
Authors: Cancienne Jourdan M. , Kandahari Adrese M. , Casp Aaron , Novicoff Wendy , Browne James A. , Cui Quanjun , Werner Brian C.
Published: November 2017

Background:

A paucity of data exists regarding long-term outcomes among patients with hepatitis C who undergo total hip arthroplasty (THA) and total knee arthroplasty (TKA).

Methods:

We queried a database for patients with hepatitis C who underwent THA and TKA. We then identified their rates of several postoperative complications and compared them with the same rates among mutually exclusive matched control cohorts.

Results:

Patients with hepatitis C who underwent THA and TKA had higher rates of infection, aseptic revision surgery, medical complications, and blood transfusion compared with matched control patients.

Discussion:

Our findings suggest that patients with hepatitis C who undergo THA and TKA are at increased risk of experiencing several postoperative complications, which could mean a substantial increase in the cost of care.

Conclusions:

Further research is needed to establish quantifiable associations between hepatitis C and postoperative complications among patients with the disease who undergo total joint arthroplasty.

The effects of language typology on L2 lexical availability and spelling accuracy
Authors: Martínez-Adrián María , Gallardo-del-Puerto Francisco
Published: December 2017

This paper explores whether language typology plays any role in lexical availability and spelling accuracy in L2 English. Two groups of adult speakers were compared: a group of native speakers of a language typologically distant from English with a logographic writing system (Chinese; n=13) vs. a group of native speakers of a language typologically closer to English with an alphabetic system (Spanish; n=14). All participants performed a lexical availability task (Carcedo González, 1998a) which was later on analyzed in terms of the ‘total number of words’ and the ‘total number of words containing spelling mistakes’ per each of the 15 semantic categories included. Spanish speakers displayed larger available lexica and fewer spelling mistakes than Chinese speakers, an outcome which would confirm the positive influence of L1-L2 proximity on L2 lexical availability and the deleterious effect of having a non-alphabetic L1 writing system on L2 spelling accuracy. 
France Daigle, héritière de Gérald Leblanc : de Moncton mantra à Petites difficultés d’existence
Authors: Brun del Re Ariane
Published: November 2017

Cet article examine comment France Daigle se fait l’héritière du projet de Gérald Leblanc en contribuant à la transformation de Moncton en capitale littéraire de l’Acadie. Nous revenons d’abord sur la fonction et la nécessité des capitales à partir des travaux de Pascale Casanova et de Raoul Boudreau. Puis, nous analysons les stratégies d’écriture mises de l’avant dans Moncton mantra de Leblanc et reprises dans Petites difficultés d’existence de Daigle pour transformer Moncton en capitale littéraire. Nous verrons que les deux écrivains font contrepoids à la taille relative de Moncton en mettant l’accent sur son urbanité. Ils présentent la ville à la fois comme un lieu cosmopolite branché sur le monde et un pôle d’attraction qui accorde une place importante à l’art et à la culture.
Les quatre saisons d’Alma : une lecture écoféministe d’Alma de Georgette LeBlanc
Authors: Papillon Joëlle
Published: November 2017

Cet article analyse les relations qu’Alma (l’héroïne du roman poétique éponyme de Georgette LeBlanc) développe avec le monde naturel en contraste avec celles de son conjoint Pierrot. Alma tisse des liens étroits avec les plantes, les animaux et les autres humains sur le territoire, reconnaissant la parenté et l’interdépendance des êtres vivants, tandis que Pierrot reproduit un modèle spéciste et hiérarchique valorisant l’humain devant les autres vivants, et l’homme au détriment de la femme. L’auteure propose que cette opposition entre une identité relationnelle (Alma) et une identité « auto-engendrée » (Pierrot) repose notamment sur la construction du genre sexuel dominante à la Baie Sainte-Marie au cours de la première moitié du vingtième siècle.

PORTRAIT PSYCHOLOGIQUE ET SOCIAL DE MÈRES INDIENNES RÉFUGIÉES : LES ENJEUX LIÉS À L’ATTACHEMENT DE L’ENFANT
Authors: Lecompte Vanessa , Richard-Fortier Zoé , Rousseau Cécile
Published: November 2017

L’objectif de cet article utilisant une lunette qualitative à partir de mesures quantitatives est de dresser le portrait de quatre mères Indiennes réfugiées vivant un stress migratoire élevé et de présenter les conséquences liées à l’attachement de l’enfant. Les résultats indiquent des niveaux cliniques d’anxiété et de dépression ainsi qu’un soutien social variable selon la source de soutien. Chez l’enfant, la sécurité d’attachement est faible, il y a absence de comportements évitants et la prévalence de comportements ambivalents et désorganisés est élevée. Les résultats suggèrent que des approches qui misent sur un soutien de la dyade mère-enfant pourraient être appropriées pour ces femmes.

L’analyse fait ressortir les dynamiques d’échange et la valeur de l’autoprotection au sein des entretiens. L’interprétation est articulée à la lumière des notions de réciprocité, de réflexivité et d’équité.
Sobre les fonts dels «exempla fabularia» de la «Disputa de l'ase»
Authors: Redondo Jordi
Published: December 2017

La Disputa de l’ase d’Anselm —Antelm? Telm?— Turmeda compta entre els textos més singulars de la prosa quatrecentista. Aquest article tracta de les fonts dels exempla esmentats a la raó setzena de l’obra, i per als quals l’excel·lent estudi de García Sempere i Martín Pascual no havia aconseguit de trobar l’origen de totes. La veritable font principal d’aquest conjunt és la Història dels animals d’Elià —font alhora del Fisiòleg grec, i aquest del llatí—, part de la transmissió manuscrita de la qual remunta al segle XIII. Ultra les nombroses coincidències de Turmeda amb, per ordre de prelació dins l’actual estat de la qüestió, els bestiaris medievals, el Fisiòleg llatí i la Risala al-hayawanat, cal apreciar aquelles on la font és tan sols Elià, la qual cosa obliga a replantejar la seua recepció a la nostra tradició literària.

Macro-economically, development is usually referred to as the social-economic growth within a region in a specific time range (e.g. one year or longer) expressed via the increase of population, GDP, index of growth of industrial and agricultural production, investments in primary capital, etc. Nevertheless, it seems that the most complete and substantial determination of regional development is the formation and development of territorial social-economic structures within a region accompanied with a stable growth of economic, social, and ecological qualities of regional development.

Alternativas tecnológicas y estrategias de riego en condiciones de sequía
Authors:   Pontificia Universidad Católica de Chile, Gurovich Luis
Published: November 2017

Entre todas las actividades productivas, sanitarias y recreacionales en las que se utiliza el agua, el riego de los cultivos agrícolas es el principal usuario de este recurso. Para fabricar una tonelada de acero, se requieren 250 m3 de agua, para refinar una tonelada de petróleo se requieren 1.000 m3 de agua y para obtener tan solo una tonelada de grano se requiere el inmenso volumen de 10.000 m3. En condiciones de sequía, la asignación de este recurso y su uso en el campo para optimizar el aporte a diferentes cultivos dentro de un predio agrfcola, implica un proceso de toma de decisiones bastante complejo y con muchas soluciones posibles; probablemente, existirá más de una tecnología y estrategia que combine oportunidad, cantidad aplicada, eficiencia y uniformidad, para satisfacer la demanda evaporativa de la atmósfera, a través del proceso de evapotranspiración, tomando en consideración las características hidrodinámicas de los suelos regados y la dinámica del desarrollo de la cobertura vegetal de los cultivos.

Frente a una escasez moderada de aguas, como primera medida dispone el derecho algo que resulta natural: deberán los usuarios recibir una menor cantidad de aguas, disminuyéndose la que indican sus Mulos, fijándose turnos o reparticiones alícuotas. No obstante, en casos de extraordinaria escasez, se debe producir el reparto de las aguas también de un modo extraordinario, y es posible llegar a una “redistribución”, que consiste, esencialmente, en la alteración de la distribución normal o, en su caso, seccionada del agua de los ríos. En este trabajo se analiza la forma en que opera unte el derecho vigente la “redistribución” del agua, que se produce en tiempos de extraordinaria sequía, teniendo en la vista el autor la posible existencia de “secciones” en un mismo río, ofreciendo un trabajo a In luz del principio de la unidad de la corriente, y sus conexiones con el principio general de igualdad ante la ley.

A house-shaped shrine in a Carolingian setting, as depicted in the oldest portrait of St Columba in Cod Sang 555
Authors: Yeoman Peter
Published: November 2017

This paper will consider the oldest known image of St Columba, contained within a copy of Adomnán’s Vita sancti Columbae, created around the middle of the 9th century in the monastery at St Gallen in Switzerland. Columba established a confederation of monasteries in Britain and Ireland, centred on his great foundation at Iona, before his death in AD 597. His fame spread to the Continent, in relation to a network of Carolingian monasteries with Scotto-Irish links, resulting in a persistent devotion to certain Irish saints, the context for which is outlined here. Rather than simply being an illustration in support of the manuscript, the image affirms the significance of Columba to the culture of St Gallen more than 200 years after his death. Most remarkably, a ‘house-shaped’ shrine – of possible Insular origin – features in the church setting of this image, and this is discussed in relation to the possible origins and identification of this object, possibly as a Columban reliquary. Whereas this paper focuses on the materiality of the image and especially on the extraordinary representation of the reliquary, an art historical assessment of the image is also essential to achieving a full understanding. As this is outwith the skills of the present author, the art historical significance will be fully explored in a forthcoming, accompanying paper by Prof Jane Geddes.
A whetstone from south-east England at Newstead, Melrose (Trimontium): the reach of a major Roman stone industry
Authors: Allen J R L
Published: November 2017

James Curle found at Newstead near Melrose an unusual whetstone of bar-shaped design, with rebates on the long edges, that is now on public display at the National Museum of Scotland (Edinburgh). It is made from a greenish-grey, calcareous, very fine-grained sandstone, attributable to sandstones in the Weald Clay Formation (Lower Cretaceous) outcropping in the Weald of south-east England. Carefully manufactured whetstones produced by a large business in this area occur throughout most of Roman Britain and are also found on the coastal mainland of north-west Europe. The Newstead example is the northernmost of its products known on a spatially exponential distribution of sites.

Importance

There is a need for early and equitable detection of cognitive impairment among older adults.

Objective

To examine the prevalence of unrecognized cognitive impairment among older adults receiving primary care from federally qualified health centers (FQHCs).

Design, Setting, and Participants

This cross-sectional study was conducted at 5 FQHCs providing primary care in Indianapolis, Indiana, between 2021 and 2023. Participants were adults aged 65 years and older, without a diagnosis of mild cognitive impairment (MCI), dementia, or severe mental illness. Data analysis was performed from September 2023 to April 2024.

Main Outcomes and Measures

The primary outcome was a diagnosis of dementia or MCI, as determined by an interdisciplinary clinical team using data from structured patient and study partner interviews, medical record reviews, and a detailed cognitive assessment, including neuropsychological testing. Differences between participants determined to have normal cognition, MCI, and dementia were assessed statistically using analysis of variance for continuous variables, χ2 or Fisher exact tests for categorical variables, or Fisher exact test alone when expected cell counts were 5 or less.

Results

A total of 844 eligible individuals were consecutively approached, 294 consented to participate, and 204 completed the study (mean [SD] age, 70.0 [5.1] years; 127 women [62.3%]). One hundred eight participants (52.9%) were African American, 5 (2.5%) were Hispanic, 199 (97.5%) were not Hispanic, and 90 (44.1%) were White. The mean (SD) duration of education was 13.1 (2.6) years, and the mean (SD) Area Deprivation Index score was 78.3 (19.9), indicating a high level of neighborhood disadvantage. In total, 127 patients (62.3%) met the diagnostic criteria for MCI, 25 (12.3%) had dementia, and 52 (25.5%) had no cognitive impairment. Compared with non-Hispanic White individuals and after adjusting for age, sex, and education level, African American individuals were more than twice as likely to have MCI or dementia (odds ratio, 2.73; 95% CI, 1.38-5.53; P = .02).

Conclusions and Relevance

This cross-sectional study found that unrecognized cognitive impairment is ubiquitous among older adults from underrepresented, minoritized racial and ethnic groups and those who are socially vulnerable receiving primary care from FQHCs. To overcome the disparity in early detection of cognitive impairment, timely, equitable, scalable, and sustainable detection approaches need to be developed.
Effect of Porosity and Gradient Parameters on Compressive Mechanical Properties of Sheet Gyroid Gradient Porous Structures and Construction of Mechanical Properties Prediction Model
Authors: Ye Xiu , Miao Xiaojin , Shi Xiaojie , Lu Peipei , Wu Meiping
Published: October 2024

A series of uniform porous structures and radial stepwise and radial linear gradient structures are designed based on sheet‐gyroid to explore the influence mechanism of porosity and gradient parameters on forming quality and compressive mechanical properties. On this basis, mathematical models for predicting mechanical properties of porous structures based on uniform, discrete gradient, and linear gradient porosity distribution are established. The volume fraction deviation of uniform porous structures increases gradually with the increase of porosity. The relative density of porous structures ranges from 96.78 to 98.79%. The influence of porosity on compressive mechanical properties is investigated, and a prediction model of the equivalent elastic modulus and yield strength of porous structures is constructed based on the generalized G‐A model. The elastic modulus of the radial stepwise gradient porous structures is predicted by combining the rule of mixing. The deviation between the predicted results and the experimental results ranges from 0.21 to 2.61%. At the same time, a prediction model of the compressive mechanical properties of the radial linear gradient porous structure is constructed, and it is found that the predicted value is somewhat different from the experimental value, which is related to the synergistic strengthening effect of the gradient porous structure.

Physical unclonable function (PUF) has emerged as a unique physical'fingerprint' that is inherently difficult to replicate. It shows tremendous application value in various hardware security areas such as identity authentication, chip anticounterfeiting, communication encryption, blockchain, etc. However, with the rapid development of 3D nanoprinting, classical PUFs constructed with disordered micro‐nanostructures face tremendous threats from physical cloning attacks. Herein, this study proposes and demonstrates the utilization of room‐temperature single‐photon emitters derived from atomic defects in randomly distributed pyramidal aluminum nitride (AlN) nanocrystals as a novel quantum PUF to resist physical cloning attacks. The fabrication of this quantum PUF on silicon (Si) wafers enables seamless integration with silicon photonic integrated circuits. The multidimensional fingerprint features of the single‐photon emitters are highly sensitive to the lattice parameters of the uneven AlN nanocrystals. Furthermore, each single photon emitter can work as a quantum random number generator to ensure the fundamental unpredictability of PUFs. The subatomic precision requirement coupled with unpredictable quantum emission behavior makes it practically impossible to attack the proposed quantum PUF, providing a promising solution for information security in the post‐quantum era.

Drug targeting is a methodology that helps to overcome the side effects of therapeutic molecules. However, insufficient targeting specificity and the on‐target/off‐site delivery leave much room for improvement in the targeting endeavors. One approach to enhance the specificity of drug targeting is to engineer artificial receptors with recognition ligands not observed in nature. To this end, artificial internalizing receptors that feature cholesterylamine as the artificial pull‐in mechanism, and an anti‐fluorescein antibody as the exofacial recognition and capture tool are developed. Fluorescein labeling is among the most routine techniques in biochemistry and can readily provide a way to make cognate derivatives for receptor‐mediated endocytosis using these artificial receptors. Herein, the synthesis and the structure‐activity relationship for these artificial receptors are detailed, their potency and efficacy in mediating drug delivery for the antibody‐drug conjugates are illustrated, and the scope and limitations of targeting the chemically engineered cells via artificial receptors are investigated. Taken together, the presented data explore an innovative approach to drug targeting and contribute to the development of techniques in cell engineering using the tools of chemistry.

The lithium‐mediated nitrogen reduction reaction (Li‐NRR) is a promising green alternative to the Haber–Bosch process for ammonia synthesis. The solid electrolyte interphase (SEI) is crucial for high efficiency and stability, as it regulates reactant diffusion and suppresses side reactions. The SEI properties are greatly influenced by the Li+ ion solvation structure, which is controllable through electrolyte engineering. Although anion‐derived SEI enhances selectivity and stability, it has typically been engineered using high‐concentration electrolytes (HCEs), which face mass transfer, viscosity, and cost issues. In this study, a localized high‐concentration electrolyte (LHCE) in the Li‐NRR is first introduced, enabling the formation of anion‐derived SEI in a low‐concentration electrolyte (LCE) by enhancing the Li–anion coordination using an antisolvent. Among various antisolvents, 1,1,2,2‐tetrafluoroethyl‐2,2,3,3‐tetrafluoropropyl ether (TTE) achieves the highest ammonia Faradaic efficiency (73.6 ± 2.5%), more than double that of the LCE (34.3 ± 2.8%) and exceeding the HCE (56.0 ± 2.8%). Systematic calculations and experimental analyses show that the LHCE exhibits anion‐rich solvation structures and forms thin, inorganic SEI. Moreover, the LHCE has advantages of low viscosity and high N2 solubility, which facilitate mass transport. This study suggests the application of LHCE as an effective electrolyte engineering strategy to enhance the Li‐NRR efficiency.

Published: October 2024

Over 90 million tons of fabric waste are generated annually by the apparel industry and there exists an urgent need to develop innovative approaches for the recycling of garments. Reversible adhesives can both enable the automation of labor‐intensive assembly processes and facilitate fabric recycling for a circular apparel economy. Herein, an adhesive formulation based on thermoreversible Diels–Alder chemistry has been developed via the combination of a furan‐functionalized methacrylate copolymer (F) with a bismaleimide (M). To establish the fine balance between adhesion strength and reversible bonding, an extensive screening on the optimal composition and molar mass of F is conducted. Methyl, 2‐ethylhexyl, and lauryl methacrylate are used to tune the Tg of F copolymers, whereas H‐bonding monomers such as methacrylic acid and 2‐hydroxyethyl methacrylate are utilized to strengthen the adhesive and improve its interactions with cotton. Following the optimization of F composition, F molecular weight, and M crosslinker, the scaled‐up thermoreversible adhesive is studied by rheometry and successfully dispensed via an automated assembly platform. The adhered fabrics are tested for the required shear and peel strength and then separated for fabric recycling by a short heat treatment followed by a simple solvent wash to remove adhesive residues.

Published: October 2024

Magnetic microrobots are controlled to exhibit a wide range of motions, allowing them to navigate complex environments and perform multifunctional tasks with high precision. This work presents a novel hybrid electromagnetic actuation system by integrating two distinct conventional configurations, such as a paired‐coils electromagnetic disc (EMD) system and a distributed electromagnetic array coil (EAC) system. In order to ensure the effective functioning of the microrobot, its motion dynamics are thoroughly analyzed to identify the critical kinetic parameters. For demonstration purposes, first, a mixing task is performed by employing a single microrobot actuated with simultaneous motions. The mixing efficiency is observed to reach 83% within 30 s, in contrast to the efficiency of control of 45%. Second, a structural reconfiguration function is demonstrated by employing an independent control of two U‐shaped microrobots to form a new I‐shaped microrobot. Last, differentiated motion control of multiple magnetic pads is demonstrated, resulting in various 2D static formations in the shapes of numbers and alphabets. The presented results hold great promise for advancing the field of microrobotics by offering a novel solution for versatile microrobot motion controls.

Published: October 2024

In this semi‐quantitative study, laser crystal microparticles which are potentially capable of generating mid‐infrared (MIR) light are incorporated into MIR transmitting optical fibers using a volumetric interface doping technique that combines interface doping with volumetric doping. Using confocal microscopy with a refractive index matching fluid, the Er:YAP microcrystals (MCs) inside the tellurite glass fiber are observed based on the detection of the green upconversion fluorescence emission of Er3+ ions, produced under excitation at 976 nm and localized at the central region within the fiber. The key outcome from this proof‐of‐concept study is that MC particles that are fused with the glass during the fiber drawing process survived heat treatment because the MC particles are exposed for a short time to a glass fluid with high viscosity of ≈105 Pa.s, which prevented the glass from exerting a dissolution effect. The survival of the MCs demonstrated the viability of the doping technique for fabricating fibers with exotic crystal‐glass combinations for applications including good refractive index matching across the pump and lasing bands of rare earth ions. This latter parameter provides significant particle size flexibility whilst minimizing additional loss from scattering especially at MIR wavelengths where the MC diameter‐to‐wavelength ratio becomes smaller.

Published: October 2024

Presently described is a sliding‐kernel computation‐in‐memory (SKCIM) architecture conceptually involving two overlapping layers of functional arrays, one containing memory elements and artificial synapses for neuromorphic computation, the other is used for storing and sliding convolutional kernel matrices. A low‐temperature metal‐oxide thin‐film transistor (TFT) technology capable of monolithically integrating single‐gate TFTs, dual‐gate TFTs, and memory capacitors is deployed for the construction of a physical SKCIM system. Exhibiting an 88% reduction in memory access operations compared to state‐of‐the‐art systems, a 32 × 32 SKCIM system is applied to execute common convolution tasks. A more involved demonstration is the application of a 5‐layer, SKCIM‐based convolutional neural network to the classification of the modified national institute of standards and technology (MNIST) dataset of handwritten numerals, achieving an accuracy rate of over 95%.

Organic polymer materials have attracted much attention in rechargeable aqueous magnesium ion batteries (AMIBs) due to their sustainability and structural designability. However, the ionic storage capability is hindered by their insufficient redox‐active sites, dissolvability in aqueous electrolytes, and short‐range conjugated structures, resulting in low energy density and poor cycling stability. Herein, a sulfur‐heterocyclic aromatic polyimide‐based organic polymer (PTDBS) is constructed with multiple redox‐active sites and long‐range conjugate, which is employed as active material for AMIB anode, achieving an outstanding Mg2+ storage capability. Benefitting from the introduced thioether bonds, PTDBS possesses an enhanced electronic conductivity and additional redox‐active sites for reversible Mg2+ coordination, thus ensuring high redox activity and superior electron affinity. As a result, the PTDBS electrode delivers ultrafast and stable Mg2+ storage in an MgCl2 aqueous electrolyte with a superior rate capacity of 98.6 mA h g−1 at 10.0 A g−1, and remarkable cycling stability over 7500 cycles with a capacity retention rate of 90.0%. Notably, the all‐organic aqueous full cell, realized by coupling the PTDBS anode and the polyindole cathode, achieves a high energy density and long lifespan. This work lays the foundation for the development of highly stable all‐organic electrode materials for large‐scale aqueous energy storage.

Lignin, as an industrial by‐product, can be used as a phenolic substancen. In this study, enzymatic hydrolysis lignin (L) was treated with potassium ferrate and phenol respectively to obtain oxidized lignin (OL) and phenolated lignin (PL). Their phenolic hydroxyl content (PhOH) increased by 29.1% and 40.5%, respectively. Then four kinds of epoxy resins were prepared, namely lignin‐free epoxy resin (LFER), L epoxy resin (LER), PL epoxy resin (PLER), and OL epoxy resin (OLER). Gel permeation chromatography (GPC) and Fourier transform infrared analyses indicated that potassium ferrate oxidation could decline the molecular weight (Mw) and increase the PhOH of L. Mechanical properties test and dynamic mechanical analysis (DMA) results show that cured OLER (OLEN) has higher crosslinking density and better mechanical properties (shear strength increased by 14%, tensile strength increased by 15%) than cured LER (LEN). Thermogravimetric analysis results show that OLEN has better thermal stability than cured LFER (LFEN) and LEN. In addition, scanning electron microscopy images showed that the modified L had better compatibility. This study presents a novel approach for lignin oxidation.
