Simultaneous grafting of carbon nanotube and hyperbranched poly(thioether‐yne) onto carbon fiber via thiol‐alkyne click chemistry to improve interface properties of carbon fiber/epoxy composite
Authors: Xiong Kun , Xiong Lei , Liu Fang , Xiong Min , Chen Tao 
Published: November 2023

AbstractAn efficient and fast technique was proposed to graft carbon nanotube (CNT) on carbon fiber (CF) using hyperbranched poly(thioether‐yne) (HPTEY) as bridging agent through thiol‐alkyne click chemistry reaction. The successful synthesis of CNT/HPTEY grafted CF (CF‐HPTEY‐CNT) was verified with Fourier transform infrared, x‐ray photoelectron spectroscopy, thermogravimetric analyzer, and scanning electron microscopy. The simultaneous introduction of CNTs and HPTEY could significantly improve the wettability and surface energy of CF, leading to that the interfacial shear strength (IFSS) of CF‐HPTEY‐CNT/epoxy composite evaluated using the microdroplet test was remarkably enhanced by 106.4% than pristine CF/epoxy composite. The bending strength for CF‐HPTEY‐CNT/epoxy composite was also significantly increased by 40.4% because of the effective stress transfer at interface. Furthermore, the monofilament tensile strength of CF‐HPTEY‐CNT showed an increase (by 3.3%) as compared with pristine CF, attributed to that the grafting CNTs and HPTEY remedied the CF surface defects. Therefore, this work is expected to offer a promising technique for developing advanced structural composite with outstanding interface and mechanical properties.Highlights

AbstractIn this work, an attempt was made to use recycled thermosetting polymer waste (RTPW) to reduce the environmental impacts. The RTPW and high‐density polyethylene (HDPE) were used to fabricate the composites using melt mixing, a twin‐screw extruder, and an injection molding machine. The weight ratios varied between the HDPE/RTPW: 100:0, 95:5, 90:10, and 85:15 and subjected to different thermal property studies. The thermal properties were evaluated by melt flow index (MFI), differential scanning calorimetry (DSC), thermogravimetric analysis (TGA), heat deflection temperature (HDT), and VICAT softening temperature (VST). Results showed a noticeable MFI increase from 9.3 to 14.6 g/10 min in HDPE + RTPW (95:5) composite samples. It was ascribed to the presence of RTPW, resulting in reduced viscosity. DSC reported a minor change in the melting temperature of HDPE due to adding 5% RTPW and 6% polyethylene‐grafted maleic anhydride. These results suggested that the HDPE's crystallinity was minimally changed. Similarly, the onset and end‐set temperatures were increased by incorporating RTPW in TGA, highlighting the influence of thermosetting polymers. Then, the HDT and VSTs were improved by adding RTPW. These observations collectively demonstrate that using RTPW enhances the thermal behavior of HDPE composites while promoting environmental sustainability.Highlights

Spontaneously self‐healing silicone polyurea coating for metal corrosion protection
Authors: Zhang Xiang , Xiao Zhenggang 
Published: November 2023

AbstractOrganic anticorrosion coatings (OACs) are the most effective, economical, and environmentally friendly protection strategy for metals. However, the traditional OACs usually inevitably suffer mechanical cracks during their service life. If not repaired in time, the resultant cracks in OACs will result in irreparable corrosion of the metal substrate. More detrimentally, these microcracks are not easily detectable at the initial stage. If OACs can autonomously heal their damage at the initial stage, the microcracks will be repaired in time and the metal substrate will be protected well. Thus, giving OACs the self‐healing capability is a promising strategy for metal protection. Herein, an autonomously self‐healing TiO2‐reinforced silicone polyurea (SPU‐g‐TiO2) elastomer was successfully designed as anticorrosion coating for Q235 carbon steel (QCS) protection. The SPU‐g‐TiO2 elastomer matrix exhibited excellent stretchability with a maximum strain of 3826.72% and fast self‐healing ability with an outstanding self‐healing efficiency of 98.69% for 6 h without any external stimulus at room temperature. The QCS coated with SPU‐g‐TiO2 showed excellent damage resistance and good anticorrosive ability, and it can self‐heal the microcracks generated in its coating in time to prevent corrosive media corroding the internal mental substrate. This work has a positive guiding significance for the development of functional OACs to improve their protection for metallic materials.Highlights

A systematic review of academic resilience in East Asia: Evidence from the large‐scale assessment research
Authors: Zheng Jia‐qi , Cheung Kwok‐cheung , Sit Pou‐seong 
Published: November 2023

AbstractAlthough academic resilience is of great concern to contemporary educational practitioners, there is no consensus on its measurement. Furthermore, protective factors characterized by East Asian societal contexts remain ambiguous. This systematic review aims to offer an overview of the operational definitions, statistical methodology, and protective factors of academic resilience identified in East Asian countries/economies. With a focus on large‐scale assessment (LSA) research, three databases (i.e., Web of Science, CNKI, and AiritiLibary) were searched and returned 31 peer‐reviewed studies over the last decade. Results indicated that the definition‐driven method was commonly adopted in international LSA studies (e.g., Programme for the International Student Assessment) to measure academic resilience, and the research conducted in national/regional LSA (e.g., China Education Panel Survey) tended to use the process‐driven approach. Logistic regression was the most frequently data analysis technique utilized in the definition‐driven approach, while structural equation modeling and mediation/moderation analyses accounted for the largest proportion of the process‐driven methods. Our study shed light on the methodological issues of academic resilience in LSA. Additionally, it highlights the aspiration of educational researchers to identify Asian‐specific protective factors from the social‐ecological perspective to propose appropriate interventions fostering academic resilience.

AbstractIntroductionChildhood Interstitial Lung Disease (chILD) represents a rare and severe group of diseases for which the etiologic workup, classification, and management remain a challenge for most pediatric pulmonologists. In France in 2018, the RespiRare network established the first multidisciplinary team meetings (MDTm) dedicated to chILD. This study aims to investigate the impact of MDTm in chILD diagnosis and management as well as user satisfaction.MethodsThe MDTm took place on a monthly basis through video conferences. The participants consisted of a quorum and included pediatric pulmonologists, radiologists, geneticists, and pulmonologists, with an average of 10.5 participants per meeting. Patients provided consent to participate in MDTm and for data collection. Data were retrospectively extracted from MDTm reports. To evaluate the usefulness of the MDTm and the satisfaction of the participants, a survey was sent by email at least 3 months after the MDTm to the participants.ResultsA total of 216 chILD cases were discussed during 56 MDTm sessions. The median age of onset was 0.5 years (interquartile range 0–7). The MDTm sessions resulted in the correction of chILD etiology in 25% of cases (neuroendocrine cell hyperplasia of infancy 17%, surfactant metabolism disorder 8%, pulmonary alveolar proteinosis 4%, hemosiderosis 3%, sarcoidosis 3%, and others 34%), and chILD was ruled out in 7% of cases. A change in therapy was proposed for 46% of cases. User satisfaction was significant, particularly regarding their confidence in managing these rare diseases.Discussion and ConclusionDedicated MDTm sessions offer a unique opportunity to enhance chILD etiologic diagnosis and management, leading to increased physician knowledge and confidence in managing these patients.

AbstractSince the start of COVID‐19 pandemic, a huge effort has been devoted to understanding the Spike (SARS‐CoV‐2)–ACE2 recognition mechanism. To this end, two deep mutational scanning studies traced the impact of all possible mutations across receptor binding domain (RBD) of Spike and catalytic domain of human ACE2. By concentrating on the interface mutations of these experimental data, we benchmarked six commonly used structure‐based binding affinity predictors (FoldX, EvoEF1, MutaBind2, SSIPe, HADDOCK, and UEP). These predictors were selected based on their user‐friendliness, accessibility, and speed. As a result of our benchmarking efforts, we observed that none of the methods could generate a meaningful correlation with the experimental binding data. The best correlation is achieved by FoldX (R = −0.51). When we simplified the prediction problem to a binary classification, that is, whether a mutation is enriching or depleting the binding, we showed that the highest accuracy is achieved by FoldX with a 64% success rate. Surprisingly, on this set, simple energetic scoring functions performed significantly better than the ones using extra evolutionary‐based terms, as in Mutabind and SSIPe. Furthermore, we demonstrated that recent AI approaches, mmCSM‐PPI and TopNetTree, yielded comparable performances to the force field‐based techniques. These observations suggest plenty of room to improve the binding affinity predictors in guessing the variant‐induced binding profile changes of a host–pathogen system, such as Spike–ACE2. To aid such improvements we provide our benchmarking data at https://github.com/CSB-KaracaLab/RBD-ACE2-MutBench with the option to visualize our mutant models at https://rbd-ace2-mutbench.github.io/.

Published: November 2023

SummaryThe Moon is the closest celestial body to the Earth. The examination and discovery of this planet have always played an important role in the history of humanity. Since the beginning of the space age, the Moon has been the target of many missions from the 1950s to the present day. Radio communication plays a fundamental role in space vehicle projects because this is the most obvious way to communicate with the ground station and transmit control commands and scientific data. From the early missions to the present day, Earth–Moon communication had many stages of development. In our article, we review this progress and then present the state‐of‐the‐art ideas related to the present missions through the missions currently underway and those planned for the near future. Our primary objective is to describe the radio communication relay services planned for orbit around the Moon. Furthermore, we present the European Space Agency (ESA)‐supported lunar missions, highlighting the Lunar Geology Orbiter (LUGO) mission. Finally, as a future perspective, we present the possibilities of optical communication in the Earth–Moon path, which can result a significant increase in capacity.

AbstractThere is an empirical association between stress and symptoms of food addiction (FA), but it is still not clear which domains of stress are the most relevant when it comes to FA, limiting the ability of researchers and practitioners to address problematic eating‐related health outcomes. In order to address this gap in the literature, we analysed how different domains of chronic stress are related to FA. We used data from a subsample of the LIFE‐Adult‐Study (N = 1172), a German cohort study. We conducted a linear regression analysis with stress domains (Trier Inventory for Chronic Stress, TICS) as predictors of FA (Yale Food Addiction Scale, YFAS). In the second regression analysis we included sociodemographic variables, personality, and smoking as control variables. There was a significant and positive association between Social Overload, Work Discontent, Excessive Demands from Work, and Chronic Worrying and FA. After adding control variables, only Social Overload, Excessive Demands from Work, and Chronic Worrying remained significant predictors. Connections between stress domains and FA can serve as starting points for the development of meaningful interventions that support individuals self‐care strategies (Social Overload), complexity management (Excessive Demands from Work), and coping with negative emotions (Chronic Worrying).
Self‐Assembly Pathways of Triblock Janus Particles into 3D Open Lattices
Authors: Eslami Hossein , Müller‐Plathe Florian 
Published: November 2023

AbstractThe self‐assembly of triblock Janus particles is simulated from a fluid to 3D open lattices: pyrochlore, perovskite, and diamond. The coarse‐grained model explicitly takes into account the chemical details of the Janus particles (attractive patches at the poles and repulsion around the equator) and it contains explicit solvent particles. Hydrodynamic interactions are accounted for by dissipative particle dynamics. The relative stability of the crystals depends on the patch width. Narrow, intermediate, and wide patches stabilize the pyrochlore‐, the perovskite‐, and the diamond‐lattice, respectively. The nucleation of all three lattices follows a two‐step mechanism: the particles first agglomerate into a compact and disordered liquid cluster, which does not crystallize until it has grown to a threshold size. Second, the particles reorient inside this cluster to form crystalline nuclei. The free‐energy barriers for the nucleation of pyrochlore and perovskite are ≈10 kBT, which are close to the nucleation barriers of previously studied 2D kagome lattices. The barrier height for the nucleation of diamond, however, is much larger (>20 kBT), as the symmetry of the triblock Janus particles is not perfect for a diamond structure. The large barrier is associated with the reorientation of particles, i.e., the second step of the nucleation mechanism.

AbstractThe traditional recycling methods of the spent lithium ion batteries (LIBs) involve the intricate and cumbersome steps. This work proposes a facile method of acid leaching followed by the sulfurization treatment to achieve the high Li leaching efficiency, and obtain high‐performance multi‐function electrocatalysts for oxygen reduction (ORR), oxygen evolution (OER), and methanol oxidation reactions (MOR) from the spent LIB ternary cathodes. By this method, the Li leaching efficiency from the spent LIB ternary cathode can reach 98.3%, and the transition metal sulfide heterostructures (LNMCO‐H‐450S) consisting MnS, NiS2, and NiCo2S4 phases can be obtained. LNMCO‐H‐450S shows the superior bifunctional oxygen catalytic activities with ORR half‐wave potential of 0.763 V and OER potential at 10 mA cm−2 of 1.561 V, surpassing most of the state‐of‐the‐art electrocatalysts. LNMCO‐H‐450S also demonstrates the superior MOR catalytic activity with the potential at 100 mA cm−2 being 1.37 V. Using LNMCO‐H‐450S as the oxygen catalyst, this work can construct the aqueous and solid‐state zinc‐air batteries with high power density of 309 and 257 mW cm−2, respectively. This work provides a promising strategy for the efficient recovery of Li, and reutilization of Ni, Co, and Mn from the spent LIB ternary cathodes.

AbstractCarbonized polymer dots (CPDs) with a circularly polarized fluorescence property have received increasing attention in recent years. However, it is still a great challenge to construct circularly polarized room‐temperature phosphorescence (CPRTP) CPDs. Herein, a simple approach to the synthesis of intrinsically CPRTP CPDs for the first time by utilizing sodium alginate and l‐/d‐arginine as precursors under relatively mild reaction conditions is presented. Notably, the CPDs exhibit both chirality and green RTP in solid states. Furthermore, color‐tunable CPRTP is successfully achieved by engineering chiral light‐harvesting systems based on circularly polarized phosphorescence resonance energy transfer (C‐PRET) where the CPDs with green RTP function as an initiator of chirality and light absorbance, and commercially available fluorescent dyes with different emission colors ranging from yellow to red serve as the terminal acceptors. Through one‐step or sequential C‐PRET, the light‐harvesting systems can simultaneously furnish energy transfer and chirality transmission/amplification. Given the multicolor long afterglow, lifetime‐tunable, and CPRTP properties, their potential applications in multiple information encryption are demonstrated.

AbstractFerronematics that are generally based on nematic liquid crystals (LCs) doped with magnetic nanoparticles, synergistically taking advantage of the anisotropic and flow characteristics of the nematic host and the magnetic susceptibility of the dopant, have powerful applications as magnetically actuated soft materials. In this work, a Co(II) complex, which alone presents both characteristics, is built with a salen‐type ligand 3,5‐dichlorosubstituted at the aromatic nuclei and has a tetramethyldisiloxane spacer, which makes it one of the few metallomesogens containing this structural motif. Paramagnetic crystals, through heat treatment above 110 °C, change into magnetic nematic LCs. Applying a perpendicular magnetic field of 50 mT, the nematic droplets align two by two through dipole–dipole interactions. By incorporating it into a silicone matrix consisting mainly of polydimethylsiloxane, a 3D printable ink is formulated and crosslinked under various shapes. In this environment, the cobalt complex is stabilized in an LC state at room temperature and, due to its anisotropy, facilitates the mechanical response to magnetic stimuli. The resulting objects can be easily manipulated on fluid or rough surfaces using external magnetic fields, behave like magnets by themselves, and show reversible locomotion.

AbstractIn the electrochemical CO2 reduction reaction (CO2RR), the coverages of *CO and *H intermediates on a catalyst surface are critical for the selective generation of C1 or C2 products. In this work, we have synthesized several CuxZnyMnz ternary alloy electrocatalysts, including Cu8ZnMn, Cu8Zn6Mn, and Cu8ZnMn2, by varying the doping compositions of Zn and Mn, which are efficient in binding *CO and *H adsorbates in the CO2 electroreduction process, respectively. The increase of *H coverage allows to promotion of the CH4 and H2 formation, while the increase of the *CO coverage facilitates the production of C2H4 and CO. As a result, the Cu8ZnMn catalyst presented a high CO2‐to‐CH4 partial current density (−418 ± 22 mA cm−2) with a Faradaic efficiency of 55 ± 2.8%, while the Cu8Zn6Mn catalyst exhibited a CO2‐to‐C2H4 partial current density (−440 ± 41 mA cm−2) with a Faradaic efficiency of 58 ± 4.5%. The study suggests a useful strategy for rational design and fabrication of Cu electrocatalysts with different doping for tailoring the reduction products.
Principled and practical static analysis for Python: Weakest precondition inference of hyperparameter constraints

Published: November 2023

AbstractApplication programming interfaces often have correctness constraints that cut across multiple arguments. Violating these constraints causes the underlying code to raise runtime exceptions, but at the interface level, these are usually documented at most informally. This article presents novel principled static analysis and the first interprocedural weakest‐precondition analysis for Python to extract inter‐argument constraints. The analysis is mostly static, but to make it tractable for typical Python idioms, it selectively switches to the concrete domain for some cases. This article focuses on the important case where the interfaces are machine‐learning operators and their arguments are hyperparameters, rife with constraints. We extracted hyperparameter constraints for 429 functions and operators from 11 libraries and found real bugs. We used a methodology to obtain ground truth for 181 operators from 8 machine‐learning libraries; the analysis achieved high precision and recall for them. Our technique advances static analysis for Python and is a step towards safer and more robust machine learning.
