Published: September 2024

AbstractHighly efficient electromagnetic wave (EMW)‐absorbing multicomposites can be fabricated by constructing particular structures using suitable components. Expanded graphite (EG) has a 3D, low‐density porous structure; however, it suffers from poor impedance matching and EMW absorption properties. Based on this information, in the present study, NiCo2S4 components with different morphologies are successfully loaded onto a 3D EG surface using a facile microwave solvothermal method to achieve a synergistic effect between the different components. The NiCo2S4 content is adjusted to alter the compositional morphology and electromagnetic parameters of the composites to achieve impedance‐matching and obtain excellent EMW absorption properties. The heterogeneous interface between EG and NiCo2S4 induces an inhomogeneous spatial charge distribution and enhances interfacial polarization. The defects in the material and oxygen‐containing groups induce dipole polarization, which enhances the polarization‐relaxation process of the composites. The 3D porous heterostructure of the “Fibonacci cauliflower”‐shaped NiCo2S4/EG composites results in an optimal reflection loss of −64.93 dB at a filler rate of only 14 wt.%. Analysis of the synergistic conduction loss and polarization loss mechanisms in carbon‐based materials with heterogeneous interfaces has led to the development of excellent EMW absorption materials.

Published: September 2024

AbstractMacroscopic self‐assembly of µm‐to‐mm components (dimension from 100 µm to millimeters), is meaningful to realize the concept of “self‐assembly at all scales” and to understand interfacial phenomena such as adhesion, self‐healing, and adsorption. However, self‐assembly at this length scale is different from molecular self‐assembly due to limited collision chances and binding capacity between components. Long‐time contact between components is requisite to realize µm‐to‐mm assembly. Even though the recent idea of adding a compliant coating to enhance the molecular binding capacity is effective for such self‐assembly, a trade‐off between coating thickness (several micrometers) and assembly efficiency exists. Here a new compliant coating of surface‐initiated polymer brush to address the above paradox by both realizing fast assembly and reducing the coating thickness to ≈40 nm by two magnitudes is demonstrated. Millimeter‐sized quartz cubes are used as components and grafted with oppositely charged polyelectrolyte brushes, enabling assembly in water by electrostatic attraction and disassembly in NaCl solutions. A rule of thickness‐dependent assembly chance is obtained and understood by in situ force measurements and a multivalent theory. The polymer brush strategy pushes the thickness limit of requisite compliant coating to the nanoscale for fast µm‐to‐mm self‐assembly and provides insights into rapid wet adhesion.

Published: September 2024

AbstractThis study introduces magnetized EGaIn@Fe, an innovative material synthesized by incorporating iron powder into the eutectic gallium‐indium alloy (EGaIn). Unlike traditional methods requiring electrolyte environments for electrical control, EGaIn@Fe can be manipulated using external magnetic fields, expanding control from 2D to 3D spaces. The material exhibits both active and passive splitting capabilities under magnetic and electrical control, demonstrating exceptional deformability, precision, and flexibility. EGaIn@Fe shows significant promise in applications such as microfluidic channels, circuit repair, and soft robotics. Specifically, 5 wt.% EGaIn@Fe is optimal for microfluidic tasks and circuit repairs in confined spaces, while higher concentrations (10 and 15 wt.%) enhance 3D control and reduce material usage. Additionally, 20 wt.% EGaIn@Fe displays octopus‐like movements for navigating impassable channels. EGaIn@Fe can enhance fluid manipulation in microfluidics, bridge gaps in circuit repairs, and enable flexible actuators in soft robotics, driving advancements in adaptive materials and technologies.

Published: September 2024

AbstractSodium‐ion batteries (SIBs) have emerged as one of today's most attractive battery technologies due to the scarcity of lithium resources. Aqueous sodium‐ion batteries (ASIBs) have been extensively researched for their security, cost‐effectiveness, and eco‐friendly properties. However, aqueous electrolytes are extremely limited in practical applications because of the narrow electrochemical stability window (ESW) with extremely poor low‐temperature performance. The first part of this review is an in‐depth discussion of the reasons for the inferior performance of aqueous electrolytes. Next, research progress in extending the electrochemical stabilization window and improving low‐temperature performance using various methods such as “water‐in‐salt”, eutectic, and additive‐modified electrolytes is highlighted. Considering the shortcomings of existing solid electrolyte interphase (SEI) theory, recent research progress on the solvation behavior of electrolytes is summarized based on the solvation theory, which elucidates the correlation between the solvation structure and the electrochemical performance, and three methods to upgrade the electrochemical performance by modulating the solvation behavior are introduced in detail. Finally, common design ideas for high‐temperature resistant aqueous electrolytes that are hoped to help future aqueous batteries with wide temperature ranges are summarized.
Modifying the Reactivity of Single Pd Sites in a Trimetallic Sn‐Pd‐Ag Surface Alloy: Tuning CO Binding Strength

Published: September 2024

AbstractImproving control over active‐site reactivity is a grand challenge in catalysis. Single‐atom alloys (SAAs) consisting of a reactive component doped as single atoms into a more inert host metal feature localized and well‐defined active sites, but fine tuning their properties is challenging. Here, a framework is developed for tuning single‐atom site reactivity by alloying in an additional inert metal, which this work terms an alloy‐host SAA. Specifically, this work creates about 5% Pd single‐atom sites in a Pd33Ag67(111) single crystal surface, and then identifies Sn based on computational screening as a suitable third metal to introduce. Subsequent experimental studies show that introducing Sn indeed modifies the electronic structure and chemical reactivity (measured by CO desorption energies) of the Pd sites. The modifications to both the electronic structure and the CO adsorption energies are in close agreement with the calculations. These results indicate that the use of an alloy host environment to modify the reactivity of single‐atom sites can allow fine‐tuning of catalytic performance and boost resistance against strong‐binding adsorbates such as CO.

AbstractUtilizing Diesel Oxidation Catalysts (DOC) to partially oxidize NO to NO2 is a crucial step in controlling NOx emissions from diesel engines. However, enhancing both catalytic activity and hydrothermal stability remains a significant challenge. Benefiting from abundant asymmetric oxygen vacancies and increased Mn4+ content, MnRE0.5Zr0.5 exhibits superior NO oxidation performance (T63 = 337 °C) and hydrothermal aging resistance (T52 = 340 °C) compared to the undoped sample (T53 = 365 °C). XPS, Raman, TPR, and XAS are employed to verify the elevation of oxygen vacancy concentration and Mn valence state modulation due to Zr introduction. Furthermore, compared to MnRE (1.36 eV), the formation energy of oxygen vacancies in MnRE0.5Zr0.5 is significantly reduced (0.17 eV). This work elucidates the dual regulatory role of Zr in the Mn‐RE‐Zr ternary system, providing theoretical support and guidance for the design of catalysts for atmospheric pollutant purification and industrial catalysis.

Published: September 2024

AbstractSimultaneously improving the strength and toughness of polymer‐inorganic nanocomposites is highly desirable but remains technically challenging. Herein, a simple yet effective pathway to prepare polymer‐inorganic nanocomposite films that exhibit excellent mechanical properties due to their unique composition and structure is demonstrated. Specifically, a series of poly(methacrylic acid)x‐block‐poly(benzyl methacrylate)y diblock copolymer nano‐objects with differing dimensions and morphologies is prepared by polymerization‐induced self‐assembly (PISA) mediated by reversible addition‐fragmentation chain transfer polymerization (RAFT). Such copolymer nano‐objects and ultrasmall calcium phosphate oligomers (CPOs) are used as dual fillers for the preparation of polymer‐inorganic composite films using sodium carboxymethyl cellulose (CMC) as a matrix. Impressively, the strength and toughness of such composite films are substantially reinforced as high as up to 202.5 ± 14.8 MPa and 62.3 ± 7.9 MJ m−3, respectively. Owing to the intimate interaction between the polymer‐inorganic interphases at multiple scales, their mechanical performances are superior to most conventional polymer films and other nanocomposite films. This study demonstrates the combination of polymeric fillers and inorganic fillers to reinforce the mechanical properties of the resultant composite films, providing new insights into the design rules for the construction of novel hybrid films with excellent mechanical performances.

AbstractTrixacarus caviae is a sarcoptic mange mite infesting guinea pigs. Infestation in immunosuppressed animals produces severe dermatological problems, including alopecia, intense pruritus, hyperkeratosis and non‐dermatological issues (e.g., seizures). Treatment options are limited and include topical application of macrocyclic lactones or amitraz or injectable administration of ivermectin or doramectin. Considering the severity of the disease and the challenging treatment, the present paper aimed to determine the efficacy of oral afoxolaner in a severe case of infestation with T. caviae in a pet guinea pig. One female guinea pig was referred to the New Companion Animal Clinic due to severe dermatological problems. A clinical evaluation was done, and skin scrapings were collected and examined under the microscope. Small mites were detected and morphologically identified as T. caviae. The animal was treated with a single oral dose of 2.50 mg/kg afoxolaner, and the lesions, presence/absence of mites and intensity of pruritus were evaluated periodically until 2 months post‐treatment. A week after the medication, the lesions were milder, but pruritus was still present and was attributed to the healing process. Further examinations showed significant improvement with the complete remission of clinical signs and no mites at the microscopic examination after 4 weeks. Afoxolaner was safe and effective in this guinea pig for the treatment of T. caviae mange with no repetition needed.

Published: September 2024

AbstractLightweight and multifunctional carbon fiber‐reinforced composites with low production costs are crucial for aerospace and logistics applications. In this study, the integration of compatibilizer to polylactic acid (PLA)/thermoplastic polyurethane (TPU) blends filled with carbon fiber (CF) is performed due to cost‐lowering, besides enhanced mechanical performance and processability. Composite sample loaded with 30% CF is selected and optimized by the varied amount of polymeric MDI (pM) inclusions. As the tensile resistance of PLA/TPU/30CF and PLA/TPU/30CF/pM is compared, it is found that pM additions led to enhancements in tensile strength and tensile modulus. A total of 5% of pM inclusion results in 43% increament in tensile strength of the tensile strength of PLA/TPU/30CF. Similarly, the flexural modulus and flexural strength of composites are improved by a high amount of pM. The impact resistance of PLA significantly increases after CF inclusion. The incorporation of TPU and compatibilizer shifts impact strength to higher levels. 204% improvement is achieved for PLA/TPU blend involving 5 wt% of pM concerning unfilled PLA. According to the thermo‐mechanical analysis of composites, the presence of pM yields a higher elastic modulus for PLA/TPU/CF composites. Additionally, reductions in the glass transition temperature of PLA and composites are observed since the polymer gains ductility by elastomer and compatibilizer inclusions. Scanning electron microscopy (SEM) investigations of composites visualize these findings. Results postulated that pM integration can be utilized in large‐scale production of CF‐reinforced PLA‐TPU blend systems for cost reduction and performance improvement of composite parts in logistics and aerospace applications.Highlights
The compatibilizing effect of pMDI on the PLA/TPU/CF blend system is investigated.
pMDI inclusions yield improvement in the mechanical resistance of composites.
CF‐reinforced PLA/TPU composites gain ductile behavior by the addition of TPU.
The increase in elastic modulus ensures an efficient enhancement of compatibility.
Exploring shape and size variations significance in hybrid nanofluid flow via rotating porous channel

Published: September 2024

AbstractThe current study investigates the thermal performance characteristics of metallic (Cu) and non‐metallic (TiO2) nanoparticles (NPs), considering variations in their shapes and sizes. Specifically, analysis is conducted for four distinct stable shapes of NPs. A hybrid model is developed to analyze the influence of rotating porous walls on the system, particularly focusing on the impact of the permeable Reynolds number and NPs within a specific range of , in conjunction with a Newtonian fluid under the influence of magnetohydrodynamics (MHDs). Additionally, we examine the phenomena of expansion/contraction in heat and mass transfer enhancement with chemical reactions. The governing partial differential equations (PDEs) are transformed into nonlinear differential equations using the help of similarity transformation. A 4th‐order Runge–Kutta method (RK), coupled with the shooting technique, is employed as a mathematical strategy to numerically solve these nonlinear differential equations. Boosting the values of 𝐾𝑐𝑟 from 2 to 10 enhances the mass transfer rate between both porous channels. Higher values of 𝑅𝑒, 𝑀, and 𝑅 lead to increasing skin friction coefficients for both porous channels. Raising the values of both NP volume fractions ( from 1% to 5% results in enhanced heat transfer rates particularly for much better in platelet‐shaped NPs as compared to other shapes such as spherical, brick, and cylinder. Larger values of 𝛼, M, and Re cause the radial velocity profile to exhibit opposite behaviors in the middle of the wall and momentum boundary layer thickness.

Published: September 2024

ZusammenfassungDie Elektrokonvulsionstherapie (EKT) ist eine hochwirksame Behandlungsoption bei schweren psychischen Erkrankungen. Für Menschen mit Intelligenzminderung (IM) sind die Zugangswege zur EKT bis heute erschwert, obwohl sie mindestens so häufig wie die Normalbevölkerung an psychischen Erkrankungen leiden. Im Rahmen einer systematischen Literaturrecherche und anhand eines Fallberichtes wird die wissenschaftliche Grundlage für eine EKT-Behandlung von Menschen mit IM dargestellt. Insgesamt wurden 100 Artikel mit 208 Fallberichten recherchiert und ausgewertet. Zusammengefasst sprechen diese für eine mindestens gleich gute Wirkung und ähnliche Nebenwirkungsrate im Vergleich zur Behandlung von Personen ohne IM. Neben schweren affektiven und psychotischen Störungen werden vor allem katatone Syndrome bei Menschen mit IM erfolgreich mit EKT behandelt. Eine EKT kann dabei die Lebensqualität der Patient:innen bessern und stellt nicht selten eine lebensrettende Behandlung dar. Die Rückfallprophylaxe sollte möglichst früh im Therapieprozess eingeplant werden. Leichtere Zugangsbedingungen zu einer EKT-Behandlung für Menschen mit IM zu schaffen, entspricht der wissenschaftlichen Datenlage und auch dem Recht auf eine gleichwertige Behandlung gemäß der UN-Behindertenrechtskonvention Artikel 25.

Abstract
Case
A 22-year-old man with a type IIIA open AO/OTA 61C2.2b pelvis fracture and hypotension received exploratory laparotomy, temporary open ligation of the bilateral internal iliac arteries, and retroperitoneal packing. After prompt fracture debridement, a pelvic binder was positioned over the thighs as a reduction aid and maintained for six hours during pelvis open reduction internal fixation. Bilateral anterior thigh compartment syndrome was diagnosed three hours after packing and binder removal.

Conclusion
Prolonged application of a pelvic binder to the thighs as an intraoperative reduction tool, shortly after temporary internal iliac artery ligation, may be associated with reperfusion injury and thigh compartment syndrome.
Insurance coverage and environmental risk in an evolutionary oligopoly
Authors: Colivicchi Ilaria , Iannucci Gianluca 
Published: September 2024

AbstractThis paper studies the evolution of an oligopoly market where two types of companies, brown and green, are present. Green firms adopt a less polluting technology that allows a reduction in emissions. We want to investigate the possibility of an environmental-friendly transition where insurance can give its support to cover the (endogenous) climate change loss. The model is composed of two parts. We analyze a two-stages game in which the companies maximize their profits by choosing output in the first stage and insurance coverage in the second one. Then we develop an evolutionary game to endogenize the selection of being brown or green, according to the expected random profits. We derive analytically the dynamic regimes may arise and we perform a sensitivity analysis at the stable inner steady state, where firms coexist, changing the main key parameters to understand which ones may be strategic for an ecological transition.

Published: September 2024

AbstractPast research has indicated the factors that prevented Asians/Asian Americans from seeking mental health services. However, few studies examined their experiences in receiving mental health services. This study utilized a convenience sample with a non-identifying online survey. As part of the larger survey, this analysis concentrated on addressing two open-ended questions that inquired about the obstacles and challenges that the participants encountered while receiving therapy and the strategies they employed to overcome these challenges. Using qualitative methods to analyze the data, four themes emerged to describe the obstacles Asian/Asian American clients experience in mental health services, including a lack of trust in therapy and therapists, lack of cultural understanding by therapists, language barrier, and challenges related to access and resources. Results are discussed along with best practices and clinical implications for therapists working with Asian/Asian American individuals, couples, and families.

Published: September 2024

AbstractAcculturation after settlement has been identified as a risk factor affecting the mental health of immigrant youth. Increasing rates of immigration and expanding populations of immigrant youth mean that addressing their mental is a priority. Acculturative stress is the stress-response resulting from the effects of multiple stressors that result from the need to acculturate. Among youth within the developmental stages of late adolescence and emerging adulthood, increased sensitivity to stress, and developmental demands, impact their mental health. The effects of acculturative stress place an additional burden on the mental health of immigrant youth. This scoping review examined existing literature that investigated a variety of relationships between acculturative stress and youth mental health. A comprehensive search strategy that focused on studies involving youth, mainly aged between 15-24, with a proximal history of international migration, published between 2012-2022, resulted in a collection of fifty-three studies. This review examined significant relationships between acculturative stress and major depression, anxiety disorders, eating disorders, substance misuse, behavioural problems and poor psychological wellbeing. This scoping review was truly explorative as it included youth from immigrant minorities, had no geographical limits, and included various study designs. Acculturative stress continues to be an important contributor to the mental health of youth who have a proximal history of international migration. This review provided an exploration of the state of research, identified the importance of the settlement context, and provided recommendations for the direction of future studies, supportive policies, and practice considerations, related to the mental health of immigrant youth.
