AbstractA phosphorus anode is a promising option for energy‐storage applications because of its high theoretical specific capacity and safe lithiation potential. However, the multiphase phosphorus lithiation/delithiation reactions and soluble reaction intermediates cause sluggish reaction kinetics and loss of active materials. Herein, a novel local electric field (LEF) strategy is proposed to inhibit the intermediates dissolution and promote the reaction kinetics by optimizing ionic covalent organic frameworks (iCOFs). Among them, the LEF induced by the cationic covalent organic framework effectively enhances the electrochemical performance of the phosphorus anode. The strong electrostatic interaction between the polyphosphides and cationic covalent organic framework confines the dissolution of active materials and tailors the electronic structure of polyphosphides to accelerate the reaction kinetics. The cationic covalent‐organic‐framework‐assisted phosphorus anode provides a high capacity of 1227.8 mAh g−1 at 10.4 A g−1 (8.6 C) and a high‐capacity retention of 87% after 500 cycles at 1.3 A g−1. This work not only broadens the application of iCOFs for phosphorus anode but also inspires the great potential of the local electric field in battery technology.

AbstractDevelopment of closed‐loop chemically recyclable plastics (CCRPs) that can be widely used in daily life can be a fundamental solution to the global plastic waste crisis. Hence, it is of great significance to develop easy‐to‐recycle CCRPs that possess superior or comparable material properties to the commodity plastics. Here, a novel dual crosslinked CCRP, namely, supramolecular covalent adaptable networks (supra‐CANs), is reported, which not only displays mechanical properties higher than the strong and tough commodity polycarbonate, but also exhibits excellent solvent resistance as thermosets. The supra‐CANs are constructed by introducing reversible noncovalent crosslinks into the dynamic covalent polymer networks, resulting in highly stiff and strong thermosets that also exhibit thermoplastic‐like ductile and tough behaviors as well as reprocessability and rehealability. In great contrast, the analogs that do not have noncovalent crosslinks (CANs) show elastomeric properties with significantly decreased mechanical strength. Importantly, the developed supra‐CANs and CANs can be converted back into the initial monomers in high yields and purity at room temperature, even with additives, which enables the sustainable polymer‐monomer‐polymer circulation. This work provides new design principles for high‐performance chemically recyclable polymers as sustainable substitutes for the conventional plastics.

AbstractFlexible sensor with high sensitivity, high durability, and facile fabrication process has promising applications in structural health monitoring, human–machine interface, and soft robotics areas. Digital light processing‐3D (DLP‐3D) printing can print flexible sensor in a scalable process. However, to achieve all DLP‐3D printing of flexible sensor, there still exist challenges of how to print sensing units with high sensitivity to external stimuli, interconnectors with high conductive stability at deformations, and robust interfaces between them for long‐term usage. To address this, a hybrid DLP‐3D printing method is developed, including the key steps of printing carbon nanotube/elastomer (MWCNT/EA) as sensing units and selective electrostatic self‐assembly of silver nanowires (Ag NWs) as interconnectors. As a demonstration, a flexible pressure sensor array integrated with amplifier circuit is fabricated by the method. The MWCNT/EA sensing unit with woodpile structure has nine times improved sensitivity than the solid one. The Ag NW interconnector with serpentine configuration shows insensitivity to strain and good mechanical stability. The interface between sensing unit and interconnector is mechanical robust due to the chemical bond formation under ultraviolet radiation. The flexible sensor could detect external stimuli with enhanced signals enabled by integrated amplifier circuit, exhibiting potentials of the method for flexible electronic fabrication.

AbstractAdditive manufacturing has emerged as a promising approach for fabricating graded refractive index structures that control the electromagnetic response of radio frequency (RF) devices. However, current 3D printing methods cannot produce continuous gradients from multiple materials. Here, low‐loss graded dielectrics via active mixing of nanocomposite inks composed of block copolymers and oxide nanoparticles are designed and printed. By simultaneously tailoring their rheological, printing, and their local filler particle‐to‐polymer ratio using an active mixing printhead, a conductive microstrip‐graded substrate matching network with a gradually changing dielectric response, is created. In these printed devices, the impedance of the RF signal is controlled by the graded substrate rather than by varying the conductive microstrip geometry, enabling the fabrication of smaller RF devices. This approach enables the rapid design and fabrication of high‐performance RF devices with locally tunable dielectric properties.

AbstractThe demand for green, clean, and low‐cost energy based on next generation all‐solid‐state batteries is increasing day by day. Compared with all‐solid‐state lithium‐ion batteries, all‐solid‐state sodium‐ion batteries (ASSSIBs) feature better environmental credentials, higher safety, and higher earth abundance. To develop such type of battery system, efficient solid‐state sodium electrolytes with high ionic conductivity at room temperature, wide electrochemical stability window, low electronic conductivity, and interface compatibility are needed, but are rarely reported. In this article, density functional theory and ab initio molecular dynamic simulations are performed to predict new sodium solid electrolytes, which produces a series of sodium superionic conductors with remarkable ion‐conducting properties and interface compatibility. The optimized composition discovered in this work can afford an extraordinary Na‐ionic conductivity of up to 8 mS cm−1 with an extremely low activation energy of 0.20 eV; in addition to the high chemical and electrochemical stabilities, which could be a central idea for the experimental study and accelerate the development of high‐performance ASSSIBs.

Published: November 2022

AbstractThis work presents the analytical physical modeling of undoped organic metal‐electrolyte‐semiconductor (OMES) capacitors in the framework of the Nernst–Planck–Poisson theory, including the presence of compact interfacial layers. This work derives an exact analytical solution, up to a quadrature, for the stationary electric potential and charge density distributions in both the semiconductor film and the electrolyte solution, and from them the sheet semiconductor charge and the stationary differential capacitance are obtained as a function of the applied voltage. The dependence of these magnitudes on the physical device parameters, like the ionic concentration of the electrolyte, the capacitance of the interfacial compact layers and the injected hole density is then analyzed. This work shows that ionic diffusive effects in the electrolyte can play an important role in the device response, inducing a broadening of the transition from the weak to the strong accumulation regimes. This fact can make that the strong accumulation regime is not achieved in OMES within the usual voltage operation range of these devices. The analytical solution is validated by means of finite element numerical calculations. The implications of the results obtained on the physics of electrolyte gated organic field effect transistors (EGOFETs) are discussed.
Understanding heterogeneity in technology adoption among Indonesian smallholder dairy farmers

Published: November 2022

AbstractThis study aims to understand and profile smallholder farmers' technology adoption status. We collected cross‐sectional data from 600 smallholder dairy farming households in West Java, Indonesia. A Latent class cluster analysis identified two unique clusters of smallholder dairy farmers based on patterns in their adoption status of multiple dairy farming technologies. Cluster 1 (Low awareness/low adoption) had significantly lower awareness of all technologies, and among the “aware” farmers, technology adoption rates were also significantly lower compared to Cluster 2 (High awareness/high adoption). The Low awareness/low adoption cluster was older, had less formal education, managed fewer dairy cows, had less productive and less profitable dairy enterprises, lived further away from their cooperative and farmer group leader, and had fewer contacts with dairy extension staff. Farmers' responses to questions regarding reasons underpinning nonadoption decisions suggest that farmers face multilayered and heterogenous constraints to adopting dairy technologies. This insight can assist government, policymakers, and development professionals in designing technology dissemination programs that meet the unique characteristics of subgroups of farmers, ultimately improving the adoption of technologies.

Published: November 2022

AbstractLithium‐organosulfur (Li‐OS) batteries, despite possessing high theoretical specific capacity, encounter a few practical challenges, including unsatisfactory lifespan and low active material utilization under realistic conditions. Here, diisoropyl xanthogen polysulfide (DIXPS) has been selected as a model organosulfur compound to investigate the practical feasibility of Li‐OS batteries under realistic conditions. A well‐designed freestanding carbon sponge decorated with Fe3N nanoparticles (C@Fe3N) is introduced into the Li‐OS cells as a scaffold for both Li and DIXPS. The lithiophilic property of the C@Fe3N host guides uniform lithium deposition at the anode, and the catalysis of the DIXPS conversion reaction promotes the kinetics at the cathode. Impressively, the synergistic effect of C@Fe3N leads to an extremely stable cycling performance over 1 000 cycles in a Li‐OS full cell under realistic conditions.

AbstractWe proposed a new strategy to maximize the density of acidic groups by modulating the electronic effects of the substituents for high‐performance proton conductors. The conductivity of the sulfonated 1‐MeL40‐S with methyl group corresponds to 2.29×10−1 S cm−1 at 80 °C and 90 % relative humidity, remarkably an 22100‐fold enhancement over the nonsulfonated 1‐MeL40. 1‐MeL40‐S maintains long‐term conductivity for one month. We confirm that this synthetic method is generalized to the extended version POPs, 2‐MeL40‐S and 3‐MeL40‐S. In particular, the conductivities of the POPs compete with those of top‐level porous organic conductors. Moreover, the activation energy of the POPs is lower than that of the top‐performing materials. This study demonstrates that systematic alteration of the electronic effects of substituents is a useful route to improve the conductivity and long‐term durability of proton‐conducting materials.

Published: November 2022

AbstractLateral flow immunoassay (LFIA) is a rapid, simple, and inexpensive point‐of‐need method. A major limitation of LFIA is a high limit of detection (LOD), which impacts its diagnostic sensitivity. To overcome this limitation, we introduce a signal‐enhancement procedure that is performed after completing LFIA and involves controllably moving biotin‐ and streptavidin‐functionalized gold nanoparticles by electrophoresis. The nanoparticles link to immunocomplexes forming multilayer aggregates on the test strip, thus, enhancing the signal. Here, we demonstrate lowering the LOD of hepatitis B surface antigen from approximately 8 to 0.12 ng mL−1, making it clinically acceptable. Testing 118 clinical samples for hepatitis B showed that signal enhancement increased the diagnostic sensitivity of LFIA from 73 % to 98 % while not affecting its 95 % specificity. Electrophoresis‐driven enhancement of LFIA is universal (antigen‐independent), takes two minutes, and can be performed by an untrained person.

Published: November 2022

AbstractBy combining bifunctional diglycidyl ether of bisphenol A (DGEBA) and trifunctional tris(4‐hydroxyphenyl) methane triglycidyl ether (TMTE) epoxy monomers, along with 4,4′‐dithiodibutyric acid (DTDBA) as a carboxylic acid, a variety of novel reprocessable and recyclable thermoset polymers are synthesized. The crosslinked network structures with different crosslinking densities are produced by changing the mixing ratio between DGEBA and TMTE, resulting in changes in mechanical and thermal properties of the final products. The stress relaxation and self‐healing experiments confirmed that all of these polymeric materials have covalent adaptable networks in their microstructures and perform reversible transesterification processes inside a polymer network. These thermoset polymers are completely decomposed in solution by disulfide‐thiol reduction of DTDBA with reversible cleavage or coupling capability in the presence of reducing agent, allowing chemical recycling capability into the thermoset polymer network.

AbstractThe detection of intracellular pH is crucial for elucidating the pathological process of cancers, as well as for medical diagnostic applications. Here, we developed an aggregation‐induced emission active pH‐responsive fluorescent probe (TPE‐DCP) for sensitively detecting cell pH changes. The probe shows obvious pH‐sensing properties at ~615 nm, with a pKa value of 6.82 and a good linear pH response ranging from 8.5 to 4.5. TPE‐DCP holds advantages such as excellent anti‐interference performance, good photostability, and low cytotoxicity, and has been successfully used to image intracellular pH changes in cells.

Published: November 2022

AbstractBackgroundCell metabolism and long noncoding RNA (lncRNA) played crucial roles in cancer development. However, their association in colon adenocarcinoma (COAD) remains unclear.MethodsThe COAD gene expression data and corresponding clinical data were retrieved from The Cancer Genome Atlas (TCGA) database. Differential expression of metabolic genes and lncRNA were identified by comparing tumor and normal colon tissues. Pearson correlation analysis was performed to identify metabolism‐associated lncRNA. COAD patients were divided into training cohort and validation cohort by randomization. Then, a univariate Cox regression analysis was introduced to evaluate the correlations between metabolism‐related lncRNAs and overall survival (OS) of the patients in the training cohort. The least absolute shrinkage and selection operator (LASSO) method was introduced to determine and establish a prognostic prediction model. Subsequently, survival analysis, receiver operating characteristic (ROC) curve analysis, and Cox regression analysis were generated to estimate the prognostic role of the LncRNA risk score in training, validation, and entire cohorts.ResultsWe identified 152 differentially expressed metabolism‐associated lncRNAs (MRLncRNAs). A prognostic prediction model involving four metabolism‐related lncRNAs were established using LASSO. In each cohort, COAD patients in the high‐risk group had worse OS compared to those in the low‐risk group. The ROC analyses demonstrated that the lncRNA signature performed well in predicting OS. Uni‐ and multivariate analysis indicated that the lncRNA signature as an independent prognostic factor. Furthermore, a correlation analysis demonstrated that LINC01138 was the most closely lncRNA related to metabolic genes. In vitro assays demonstrated that LINC01138 affects tumor progression in COAD.ConclusionsIn summary, we established a metabolism‐associated lncRNAs model to predict the prognosis in COAD patients.

AbstractBackgroundWe investigated risk factors influencing the outcome of unexpected ovarian carcinomas.MethodsWe reviewed the ovarian carcinoma patients treated at atertiary medical institution between 2000 and 2017 and analyze the clinico‐pathological characteristics, treatment strategies, recurrence status, and outcome.ResultsA total of 112 women (65 primary laparoscopic surgery [LSC] and 47 laparotomic surgery [LAPA]) were included in the analysis. The LSC group had smaller ovarian tumors (10.5 ± 7.3 cm vs. 16.6 ± 8.7 cm, p = 0.031) and higher incidence of subsequent staging surgery (56.9% vs. 25.5%, p = 0.0001) compared to the LAPA group. There were 98/112 (86.6%) of early stages (I/II) diseases. The difference between the recurrent rate (27.7% vs. 31.9%), disease‐free survival (DFS), and overall survival (OS) were not significant among surgical groups. In the multivariate analysis, FIGO stage (stage II hazard ratio [HR] 6.61, p = 0.007; stage III HR 8.40, p = 0.002) was the only prognostic factor for DFS. FIGO stage (stage II HR 20.78, p = 0.0001; stage III HR 7.99, p = 0.017), histological type (mucinous HR 12.49, p = 0.036), and tumor grade (grade 3 HR 35.01, p = 0.003) were independent prognostic factors for OS, while women with latency >28 days from primary to staging surgery had significantly poorer OS (p = 0.008). Women with latency >28 days between primary surgery and adjuvant chemotherapy had similar DFS (p = 0.31) and a trend of poorer OS (p = 0.064).ConclusionsThe prognosis of unexpected ovarian cancer is independent from the primary surgical procedure and comprehensive staging surgery should be performed at close proximity after the diagnosis of unexpected ovarian malignancy.

Published: November 2022

AbstractIn a context of re‐greening of urban spaces, it is crucial to examine the impact of green spaces on the population. In this qualitative study carried out in France (Nantes), 28 people with a plot in an allotment garden were questioned through semi‐directive interviews about the psychosocial impact of this type of space. Using thematic and lexicometric analyses, the different psychosocial benefits of these spaces are highlighted and put into perspective with the conflicts occurring there. The content analysis foregrounded the benefits of allotment garden regarding psychological well‐being, (notably through the feeling of flow), physical health, self‐development and social bonding. Nevertheless, these benefits are balanced by the different conflicts reported by the participants. By showing that positive and negative social aspects are significantly associated in the participants' discourse, the lexicometric analysis strengthened the idea that these elements must be considered jointly to better describe the reality of allotment gardens.

Published: November 2022

AbstractRu/Zr(OH)4 was developed as an effective transfer hydrogenation catalyst for a broad substrate scope, including nitro, alkene, and aldehyde/ketones groups without additives. XPS study and catalyst evaluation indicated that Ru0 was the main active catalytic species during the reaction. FT‐IR and CO2‐TPD analysis showed that Zr(OH)4 has abundant basic sites. The synergistic effect of Ru metal and basic sites of Zr(OH)4 support provides Ru/Zr(OH)4 with good catalytic activity without additional base addition. Ru−H− active species was detected by 1H solid‐state NMR, and the mechanism of nitrobenzene transfer hydrogenation was proposed. Ru/Zr(OH)4 catalyst was stable and can be reused for at least 5 cycles with only slight loss of activity and selectivity. This methodology provides an environmentally benign process for transfer hydrogenation under additives‐free conditions with the advantages of high activity, stability, and broad substrate scope.
