Published: September 2022

AbstractCobalt‐rich materials have generally been recognized as the prevailing candidates of cathodes for low‐temperature solid oxide fuel cells (LT‐SOFCs, 400–600 °C). Regrettably, their instability and high cost are the major concerns for future commercialization. In response to these drawbacks, here, an A‐site‐deficient low‐cobalt‐containing perovskite‐type oxide, Ba0.95Fe0.7Co0.2Sc0.1O3‐δ (BFCS0.95), as an efficient bifunctional electrode with triple‐conducting (H+|O2−|e−) nature for oxygen‐ion conducting SOFCs (O‐SOFCs) and proton conducting SOFCs (H‐SOFCs) is proposed. BFCS0.95 electrode exhibits impressive versatility in catalyzing oxygen reduction reaction, i.e., ultralow area‐specific resistances (0.072 Ω cm2 for O‐SOFCs and 0.4 Ω cm2 for H‐SOFCs at 550 °C, respectively), extraordinarily high power outputs (1092 mW cm−2 for O‐SOFCs and 419 mW cm−2 for H‐SOFCs at 550 °C, respectively), excellent long‐term durability (>100 h for O‐SOFCs and H‐SOFCs at 600 °C), remarkable reversibility between pure air and CO2‐containing air, and superior resistance against temperature fluctuations. The combined experimental and computational studies elucidate the roles of A‐site deficient state and triple‐conducting behavior, both of which are essential to overall electrochemical performance. Low‐cobalt‐containing feature also makes BFCS0.95 cathode economically competitive among all cobalt‐containing analogues. Overall, the finding paves a highly efficient route to develop bifunctional electrodes for LT‐SOFCs toward a sustainable energy future.

AbstractCompared with raw rectorite microplatelets (RMs), rectorite nanosheets (RNs) have considerably greater application prospects in the preparation of advanced composite materials because of their larger aspect ratio, higher surface reactivity, and intrinsically superior mechanical and physical properties. However, the difficulty in the efficient preparation of RNs significantly limits their large‐scale applications. Here, a scalable poly(vinylpyrrolidone)‐assisted stirring approach is developed to prepare ultrathin RNs from the abundant natural RMs. A higher production rate (≈0.675 g h−1) is achieved compared with that of most other nanosheets. Additionally, instead of using conventional time‐ and energy‐consuming high‐speed centrifugation, an efficient poly(dienedimethylammonium chloride)‐assisted sedimentation strategy is proposed here to rapidly separate the exfoliated RNs from the RN dispersion. Then, the RNs are co‐assembled with aramid nanofibers (ANFs) into large‐scale nacre‐mimetic ANF‐RN nanopapers with considerably enhanced mechanical, electrical insulating, and high‐temperature‐resistant properties compared with pure ANF nanopapers and ANF‐RM micropapers. Moreover, these properties are superior to those of previously reported ANF‐based nanopapers and commercial insulating micropapers.

AbstractDeveloping reactive oxygen species (ROS)‐scavenging nanostructures to protect and regulate stem cells has emerged as an intriguing strategy for promoting tissue regeneration, especially in trauma microenvironments or refractory wounds. Here, an electronic modulated metal oxide is developed via Mn atom substitutions in Co3O4 nanocrystalline (Mn‐Co3O4) for highly efficient and multifaceted catalytic ROS‐scavenging to reverse the fates of mesenchymal stem cells (MSCs) in oxidative‐stress microenvironments. Benefiting from the atomic Mn‐substitution and charge transfer from Mn to Co, the Co site in Mn‐Co3O4 displays an increased ratio of Co2+/Co3+ and improved redox properties, thus enhancing its intrinsic and broad‐spectrum catalytic ROS‐scavenging activities, which surpasses most of the currently reported metal oxides. Consequently, the Mn‐Co3O4 can efficiently protect the MSCs from ROS attack and rescue their functions, including adhesion, spreading, proliferation, and osteogenic differentiation. This work not only establishes an efficient material for catalytic ROS‐scavenging in stem‐cell‐based therapeutics but also provides a new avenue to design biocatalytic metal oxides via modulation of electronic structure.

AbstractLithium (Li) metal has earned valuable status among the most auspicious anodes for the assembly of next‐generation rechargeable batteries. However, the dendritic growth and infinite change in volume of metallic Li anode strongly hinder its use for practical applications. Here, the preparation of atomically dispersed iron doped ZIF‐8 through pyrolysis (Fe@NC) to lower the Li nucleation overpotential and control the Li deposition on specific positions is reported. Thermodynamic and kinetic simulations show that the doped single Fe atoms can improve the atomic structure, increase the adsorption energy and enhance the diffusion capacity of Li. Moreover, the specific framework structure of Fe@NC can induce Li metal to nucleate in interior space of the material which can hinder the Li growth along one direction and restrain its volume expansion. As‐fabricated electrode displays nearly no nucleation overpotential at current density of 2 mA cm–2 and offers higher average Coulombic efficiency up to 99.0% for 100 cycles at current density 2 mA cm–2, and higher areal capacity up to 5 mAh cm–2. Also, the fabricated Fe@NC/LiFePO4 based full cells exhibit a longer lifespan of 100 cycles at 0.5 C. The results provide new insights for future rechargeable Li metal batteries.
The Role of Cobalt Clusters (Con, n = 1–5) Supported on Defective γ–Graphyne for Efficient Hydrogen Adsorption: A First Principles Study

Published: September 2022

AbstractIn this theoretical work, density functional theory calculations show the effect of small cobalt clusters (Con, n = 1–5) adsorbed on pristine γ‐graphyne (γ‐GY), and modify N‐doped γ‐GY monolayers (GYNs‐def). Different geometrical configurations are assessed with the adsorption energy, charge transfer, and density of states. The system with vacancy defects shows a large adsorption energy (19.96 eV) for the Co5 cluster. This behavior may be associated to the overlapping of the electronic state contributions between cobalt and carbon atoms in the valence states. This indicates that the Co5 cluster could be deposited on N‐doped γ‐GY monolayers (Con@GYNs‐def). The lowest‐energy systems are evaluated to estimate the strength of the interaction with hydrogen molecules (xH2, where x = 1–5). According to the adsorption energy values, the modified γ‐GY monolayers are allowed to be a suitable support material to capture H2 molecules via the small Con clusters. The hydrogen retention capacity for the supported cobalt atoms corresponding to the lowest‐energy configurations and larger systems are evaluated by using molecular dynamics simulations with the Born–Oppenheimer approximation. The role played by defects in the GYNs‐def monolayers is important, since the Con clusters remain attached to the vacancy with the absence of surface diffusion. This study may represent a guide to tailor novel nanostructures based on small cobalt clusters supported on graphyne monolayers modified to be applied in H2 adsorption.
Cost of free open‐access medical education (FOAM): An economic analysis of the top 20 FOAM sites

Published: September 2022

AbstractBackgroundFree open‐access medical education (FOAM) is a growing resource within the field of medicine, in particular, emergency medicine. Yet despite FOAM's contribution to advancing medical education, the precise value of FOAM has never been calculated. As a result, content creators have not been acknowledged, either financially or academically, for their deliverables. The aim of this paper was to meet this challenge by determining a value for the top 20 FOAM sites as determined by web traffic in emergency medicine through two approaches. The first approach was to value the websites through a market‐based method, where the value of the website was extrapolated from the number of blog posts published. The second approach was through a traffic analysis for each website.MethodsThe top 20 FOAM websites in emergency medicine were identified and the monetary value of each resource was calculated through two methods, the first by extrapolating the number of blog posts published by each resource and the second through traffic analysis conducted by a third‐party industry specialist based on the number of unique visitors and page visits.ResultsThe median page views per month was 194,850 and the median number of unique visitors was 138,350. Based on the content valuation method, the median value of content produced in a year was $2337.06 per website. Through the traffic valuation method, the median overall value of a website was $22,815.ConclusionsAlthough two different approaches were used to value FOAM, both came to the same conclusion that there is substantial economic value being produced. This value should not go unrewarded and content creators should be acknowledged either academically or financially for their contributions.

AbstractSudden infant death with dysgenesis of the testes syndrome (SIDDT) is a rare autosomal recessive disorder associating developmental sex disorder (DSD) in patients with 46,XY karyotype and visceroautonomic dysfunction responsible for sudden infant death. First described in 2004, very few patients have since been reported. We describe here a new patient with SIDDT and epileptic encephalopathy (EE). We provide the phenotypic description and genetic results of a boy carrying biallelic TSPYL1 deleterious variants. We also reviewed the data of the 26 previously described patients with SIDDT. Our patient presented gonadal dysgenesis, cardio‐respiratory dysfunction, and repeated seizures, leading in 1 month to severe intractable EE. He died at age 10 months of cardiorespiratory arrest. Four other reported patients from two families presented with progressive epilepsy, including one with severe EE. No similar phenotype was described in the 22 other patients and the recurrent variant p.Val242Glufs*52 appears to be more frequently associated with seizures. To note, our patient is the first case with compound heterozygous TSPYL1 variants. These findings expand the phenotypic spectrum of SIDDT by reporting progressive epilepsy and severe EE as a possible outcome. This information may help in managing patients with SIDDT.

AbstractChanges in the working, study and social lives of emerging adults due to the COVID‐19 pandemic have led to greater need for external supports. Many who lived independently may have sought that support by returning to live with parents. This study identifies factors associated with returns made between 2019 and 2020. It describes supports needed and obtained, relationships between parents and their resident emerging adults and identifies correlates of poor coping and high psychological distress. Data from the Longitudinal Surveys of Australian Youth and the Longitudinal Study of Australian Children were used and showed half of the emerging adults who moved did so due to COVID‐19 restrictions. Loss of work and increased need for emotional and financial support were key drivers of moves. Nineteen per cent who returned found spending more time with family difficult and over half did not have their support needs fully met, increasing their odds of poor coping at that time (OR = 2.9, 4.3, respectively) and subsequent psychological distress (OR = 6.0). Families were an important source of support but could not necessarily mitigate all challenges; for some emerging adults, returning to live with parents gave rise to additional difficulties which negatively affected mental health.

Authors: Park Michelle , Kapoor Shrey , Yi Julie , Hura Nanki , Lin Sandra Y. 
Published: September 2022

AbstractBackgroundSublingual immunotherapy (SLIT) adherence in the literature is often evaluated in closely monitored trials that may impact patient behavior; real‐world SLIT adherence is relatively unknown. This systematic review intends to assess SLIT adherence in studies that reflect real‐world settings.MethodsA literature search of PubMed, Embase, Cochrane, Web of Science, and Scopus for real‐world studies examining SLIT adherence was performed. Monitored clinical trials were excluded. Paired investigators independently reviewed all articles. For this review, “persistence” was defined as continuing therapy and not being lost to follow‐up and “adherence” as persistence in accordance with prescribed SLIT dose, dosing schedule, and duration. Article quality was assessed using a modified Newcastle–Ottawa scale and then converted to AHRQ standards (good, fair, and poor).ResultsThe search yielded 1596 nonduplicate abstracts, from which 32 articles (n = 63,683 patients) met criteria. Twenty‐six (81%) studies reported persistence rates ranging from 7.0% to 88.7%, and 18 (56%) reported adherence rates ranging from 9.6% to 97.0%. Twenty‐one (66%) studies surveyed reasons for discontinuing SLIT. All studies were Oxford level of evidence 2b and of good (n = 12) to fair (n = 20) quality.ConclusionReported rates of real‐world SLIT persistence and adherence varied widely by study methodology (e.g., follow‐up duration, objective vs. subjective assessment). Studies with longer follow‐up generally reported lower rates; 3‐year persistence ranged from 7% to 59.0% and 3‐year adherence from 9.6% to 49.0%. Future studies of SLIT adherence would benefit from following concordant definitions of persistence/adherence and standardized reporting metrics.
Immobilization of biogenic silver–copper nanoparticles over arylated biochar from sugarcane bagasse: Method and catalytic performance

Published: September 2022

There is an ever‐growing demand for biochar production and its chemical transformation into specialty materials. Herein, we suggest a versatile method to elaborate Ag/Cu nanoparticles, by phytochemical process, on aryl‐sulfonated sugarcane bagasse pulp‐derived biochar. A binary nanocomposite has been fabricated through a four‐step strategy. The raw substrate biochar was first prepared by a slow pyrolysis of the biomass at 500°C under N2:H2 95%:5% inert atmosphere. Thereafter, in situ arylation of the biochar surface has been performed to obtain SO3H‐Biochar. The loading of silver and copper ions on SO3H‐Biochar has been achieved via a wet impregnation using a hydroalcoholic medium. Finally, the natural extract obtained from sugarcane bagasse has been employed to ensure the reduction of the adsorbed metal ions and obtain SO3H‐Biochar@Ag/Cu. Interestingly, the structural analysis of SO3H‐Biochar@Ag/Cu and the study of the evolution of D to G band intensity and area ratios have revealed that the metal phase deposition has altered the SO3H‐Biochar surface properties. It finally provided a more graphitized nanocomposite compared with the bare biochar and the intermediate substrate (SO3H‐Biochar). Such a result suggests that the phytochemical reduction has catalyzed the substrate graphitization. The catalytic performance of SO3H‐Biochar@Ag/Cu has been investigated in the oxidative degradation of malachite green oxalate. A total mineralization of the dye has been registered, and the experimental data were found to give a best fitting to the pseudo‐first‐order model. The fitting was relatively good with a mineralization apparent constant rate equals to 65 10−3 min−1. It is worth mentioning that all experiments used a relatively low amount of the composite catalyst (2.5 mg). So to recap, this route takes advantage of the two phases of sugarcane bagasse to generate a robust biochar‐based catalyst, its solid phase to derive biochar substrate with particular properties, and its liquid extract to be used as natural reducing preparation.

Published: September 2022

AbstractThe implementation of high‐temperature superconducting (HTS) power transmission has the potential to revolutionize the efficiency of electrical grids and help unlock a fully electric transportation infrastructure. Realizing the benefits of HTS systems has been impeded by a lack of available dielectric insulation materials that can (1) withstand the extreme cryogenic operating environment of superconductors and (2) demonstrate low temperature processing that is compatible with existing superconductor manufacturing methods. In this study, a silicon dioxide reinforced polyamide (PA/SiO2) nanocomposite with exceptional thermal stability has been developed as a solid dielectric coating solution. Thermomechanical characterization of the fabricated nanocomposite is conducted to explore multi‐scale material property relationships relevant to the sought applications. The multifunctionality of the processed nanocomposite is demonstrated by an improved thermomechanical performance for cryogenic conditions and low temperature processing without decrements in certain mechanical properties. Additional experiments to investigate the nanoparticle‐polymer interfacial mechanics are discussed. Results obtained herein present a viable option to solve the material challenges impeding wider implementation of HTS power transmission.
Development of biobased polyol from epoxidized soybean oil for polyurethane anti‐smudge coatings

Published: September 2022

AbstractIn this work, a vegetable oil‐based polyol (ERD) with high hydroxyl value was obtained from ring‐opening reaction between the renewable epoxidized soybean oil and ricinoleic acid, and further esterified with 2,2‐bis(hydroxymethyl)propionic acid. To achieve anti‐smudge coating, the ERD polyol was utilized as the polyol component, hexamethylene diisocyanate trimer was employed as the curing agent, and mono‐hydroxy‐terminated polydimethylsiloxane (PDMS‐OH) was introduced as the low surface energy component. In consequence, the biobased polyurethane anti‐smudge coatings are highly smooth and transparent. With the incorporation of 1 wt% of PDMS‐OH, the obtained coating exhibited superb anti‐ink and self‐cleaning performance. Droplets of water, soy sauce, carbon ink, hexadecane, rice bran oil, and pump oil could slide off the coating surface without leaving any wetting footprints. More importantly, the coating was mechanically robust. Even after the coating was subjected to 2000 writing and erasing cycles with an oil‐based marker pen, it still displayed good ink shrinkage ability and the ink traces could be easily erased. Besides, this anti‐smudge coating retained its good hydrophobicity after being soaked in aqueous solutions with different pH values for 24 h. Therefore, the application of this biobased anti‐smudge coating would offer a lower carbon footprint than its petroleum‐based counterparts.

Published: September 2022

AbstractThis paper deals with the global asymptotic stabilization problem for discontinuous nonlinear time‐varying switched systems in the sense of fractional‐order. Via the designed periodic switching law, some criteria are firstly developed. It is shown that the derivatives of the constructed Lyapunov functions are allowed to be indefinite. Several corollaries are further derived, and some existing results can be regarded as special cases of our obtained results. Finally, our findings are verified by three numerical examples and one experiment.
Non‐small cell lung cancer in China

Published: September 2022

AbstractIn China, lung cancer is a primary cancer type with high incidence and mortality. Risk factors for lung cancer include tobacco use, family history, radiation exposure, and the presence of chronic lung diseases. Most early‐stage non‐small cell lung cancer (NSCLC) patients miss the optimal timing for treatment due to the lack of clinical presentations. Population‐based nationwide screening programs are of significant help in increasing the early detection and survival rates of NSCLC in China. The understanding of molecular carcinogenesis and the identification of oncogenic drivers dramatically facilitate the development of targeted therapy for NSCLC, thus prolonging survival in patients with positive drivers. In the exploration of immune escape mechanisms, programmed cell death protein 1 (PD‐1)/programmed death‐ligand 1 (PD‐L1) inhibitor monotherapy and PD‐1/PD‐L1 inhibitor plus chemotherapy have become a standard of care for advanced NSCLC in China. In the Chinese Society of Clinical Oncology's guidelines for NSCLC, maintenance immunotherapy is recommended for locally advanced NSCLC after chemoradiotherapy. Adjuvant immunotherapy and neoadjuvant chemoimmunotherapy will be approved for resectable NSCLC. In this review, we summarized recent advances in NSCLC in China in terms of epidemiology, biology, molecular pathology, pathogenesis, screening, diagnosis, targeted therapy, and immunotherapy.
