AbstractPurposeTo identify high‐priority risks in a clinical trial investigating the use of radiation to alleviate COVID‐19 pneumonia using a multi‐phase failure modes and effects analysis (FMEA).MethodsA comprehensive FMEA survey of 133 possible causes of failure was developed for the clinical trial workflow (Phase I). The occurrence, severity, and detection risk of each possible cause of failure was scored by three medical physicists. High‐risk potential failure modes were identified using the risk priority number (RPN) and severity scores, which were re‐scored by 13 participants in radiation oncology (Phase II). Phase II survey scores were evaluated to identify steps requiring possible intervention and examine risk perception patterns. The Phase II participants provided consensus scores as a group.ResultsThirty high‐priority failure modes were selected for the Phase II survey. Strong internal consistency was shown in both surveys using Cronbach's alpha (αc ≥ 0.85). The 10 failures with the largest median RPN values concerned SARS‐CoV‐2 transmission (N = 6), wrong treatment (N = 3), and patient injury (N = 1). The median RPN was larger for COVID‐related failures than other failure types, primarily due to the perceived difficulty of failure detection. Group re‐scoring retained 8/10 of the highest‐priority risk steps that were identified in the Phase II process, and discussion revealed interpretation differences of process steps and risk evaluation. Participants who were directly involved with the trial working group had stronger agreement on severity scores than those who were not.ConclusionsThe high ranking of failures concerning SARS‐CoV‐2 transmission suggest that these steps may require additional quality management intervention when treating critically ill COVID‐19+ patients. The results also suggest that a multi‐phase FMEA survey led by a facilitator may be a useful tool for assessing risks in radiation oncology procedures, supporting future efforts to adapt FMEA to clinical procedures.

ObjectiveIrreversible organ damage is common in patients with systemic lupus erythematosus (SLE). Despite evidence of increased prevalence and severity of SLE in Asia Pacific, organ damage is less well studied in this region. This systematic review aims to identify predictors of organ damage in SLE in the Asia Pacific region.MethodsWe searched Medline, PubMed, Embase, and Web of Science for observational studies on organ damage in adult patients with SLE in Asia Pacific from August 31, to September 5, 2022. Study selection and data extraction were completed by two independent reviewers using Covidence systematic review software. Risk of bias was assessed using the Newcastle‐Ottawa Scale and Joanna Briggs Institute tool. Significant results from univariable and multivariable analyses were synthesized from included studies.ResultsThirty‐eight eligible studies were selected from 1999 to 2022; 22 (58%) of these reported organ damage at study enrollment and 19 (50%) reported damage accrual, as measured by the Systemic Lupus International Collaborating Clinic/American College of Rheumatology Damage Index. Factors predictive of organ damage included older age, glucocorticoid use, longer disease duration, and disease activity. Lupus nephritis was a risk factor for renal and overall damage accrual. Hydroxychloroquine was protective against overall organ damage.ConclusionPredictors of organ damage in SLE in Asia Pacific are similar to other regions. Although glucocorticoid use is a modifiable risk factor for organ damage, the impact of immunosuppressives and biologic therapies needs further investigation. Effective strategies in early disease are needed to minimize initial organ damage as it predicts subsequent damage accrual.

Published: January 2024

AbstractThe thermal Hall effect (THE) is an important experimental probe of band topology and elementary excitations. Here, a large thermal Hall angle (THA) κxy/κxx ≈ 7 × 10−3 discovered so far in ferrimagnetic spinel FeCr2S4 and a large thermal Hall conductivity (κxy) discovered first in spinel structure and reaching a magnitude of at 50 K with a small magnetic field of 0.1 T are reported. These results suggest the emergence of nontrivial topological excitations in FeCr2S4. A large THA in spin caloritronics devices means that a small number of excitations can produce a large transverse signal. FeCr2S4 is therefore a potential platform for spintronics‐magnonics applications, and may enhance the knowledge of the thermal Hall effect.

AbstractBacterial infection and inferior osseointegration are major complications associated with titanium (Ti) based implants. Although surface‐engineered zinc oxide (ZnO) nanorods exhibit remarkable antibacterial ability, their potential biomedical applications are hampered by their pronounced cytotoxicity. Herein, inspired by the in vivo degradation process of znic, ZnO nanorods are converted into thermodynamically more stable zinc phosphate (Zn3(PO4)2 ）through a simple hydrothermal treatment in a hydrogen phosphate solution. By adjusting the conversion ratio, the surface morphology, release of zinc ions (Zn2+), and generation of reactive oxygen species can be finely tailored to overcome the cytotoxicity of ZnO nanorods while preserving their antibacterial capability. Furthermore, an optimized amount of Zn2+ released from the ZnO/Zn3(PO4)2 hybrid coating enhances osteogenic differentiation and extracellular matrix mineralization of human bone marrow mesenchymal stem cells by reprogramming their metabolic configuration. An implant‐related infection model in rabbit femurs indicates that the hybrid ZnO/Zn3(PO4)2 coating can even promote osseointegration in the presence of pathogenic bacteria. This surface modification strategy which endows Ti‐based implants with superior anti‐bacterial and pro‐osteogenic properties holds great clinical potential for orthopedic and dental applications.
Built‐In Electric Field of In Situ Formed Artificial Interface Layer Induces Fast and Uniform Sodium‐Ions Transmission to Achieve a Long‐Term Stable Sodium Metal Battery Under Harsh Conditions

Published: January 2024

AbstractSodium metal batteries have emerged as potential rivals to lithium‐ion batteries. Nevertheless, maintaining a stable sodium metal anode under harsh conditions (current density >10 mA cm−2) is extremely challenging. The primary issue is the highly reactive sodium metal continuously reacts with the electrolyte to form a thick and loose solid electrolyte film. The tip effect causes sodium ions (Na+) accumulated in the bulge resulting in uneven deposition. In this paper, a unique artificial interfacial layer (Ag nanoparticles distributed in NaClO4‐based matrix) is prepared on the surface of a metallic sodium anode using in situ displacement reaction. Ag particles arranged at the bottom of the artificial layer act as effective nucleation sites helping Na+ deposit uniformly, while the built‐in electric field formed between Ag in the middle/top of the artificial layer and the sodium accelerates the migration of Na+ in the interfacial layer during the deposition and reduce the polarization. Such important properties further allow the steady operation of modified sodium metal batteries in very harsh conditions. The symmetric battery achieves reversible stripping/plating for over 1000 h under high current density (10 mA cm−2). Moreover, the full cell coupled with a high‐loading Na3V2(PO4)3 cathode (20 mg cm−2) presents a stable cycle performance.

Published: January 2024

AbstractSodium layered‐oxides (NaxTMO2) sustain severe interfacial stability issues when subjected to battery applications. Particularly at high potential, the oxidation limits including transition metal dissolution and solid electrolyte interphase reformation are intertwined upon the cathode, resulting in poor cycle ability. Herein, by rearranging the complex and structure of the Helmholtz absorption plane adjacent to NaxTMO2 cathodes, the mechanism of constructing stable cathode/electrolyte interphase (CEI) to push up oxidation limits is clarified. The strong absorbent fluorinated anions replace the solvents into the inner Helmholtz plane, thereby reorganizing the Helmholtz absorption structure and spontaneously inducing anion‐dominated interphase to envelop more active sites for layered oxides. More importantly, such multi‐component CEI proves effective for the long‐term durability of a series of manganese‐based oxide cathodes, which achieves a 1500‐cycles lifetime against high oxidation voltage limit beyond 4.3 V. This work unravels the key role of breaking high‐oxidation limits in attaining higher energy density of layered‐oxide systems.

AbstractDendrite‐free Zn metal anodes with high depth‐of‐discharge (DoD) and robust cycle performances are highly desired for the practical application of aqueous Zn‐ion batteries. Herein, the zincophobic/hydrophilic nature of Metal‐N‐C through manipulating the electronic interactions between metal and coordination atoms is successfully reversed, thereby fabricating a zincophilic/hydrophobic asymmetric Zn‐N3Py+1Pr‐C (consisting of a Zn center coordinated with 3 pyridinic N atoms and 1 pyrrolic N atom) host, which realizes uniformed Zn deposition and a long lifespan with high DoD. The experimental and theoretical investigations demonstrate weakened interaction between pyrrolic N and metal center in the asymmetric Zn‐N3Py+1Pr‐C triggers downshift of the Zn 3d‐band‐center and a new localization nonbonding state in the N and C 2p‐band, resulting in preferred Zn adsorption to water adsorption. Consequently, the asymmetric Zn‐N3Py+1Pr‐C host delivers small Zn nucleation overpotential and high Coulombic efficiency of 98.3% over 500 cycles. The symmetric cells with Zn‐N3Py+1Pr‐C@Zn anode demonstrate 500 h dendrite‐free cycles at DoD up to 50%. The Zn‐N3Py+1Pr‐C@Zn/S‐PANI full cell also shows a robust long‐term cycle performance of 1000 cycles at 10 A g−1. This strategy of constructing zincophilic/hydrophobic Metal‐N‐C may open up their application for the dendrite‐free metal anode.

AbstractThe reversible and durable operation of sodium metal batteries at low temperatures (LT) is essential for cold‐climate applications but is plagued by dendritic Na plating and unstable solid‐electrolyte interphase (SEI). Current Coulombic efficiencies of sodium plating/stripping at LT fall far below 99.9%, representing a significant performance gap yet to be filled. Here, the solvation structure of the conventional 1 m NaPF6 in diglyme electrolyte by facile cyclic ether (1,3‐dioxolane, DOL) dilution is efficiently reconfigured. DOL diluents help shield the Na+‐PF6− Coulombic interaction and intermolecular forces of diglyme, leading to anomalously high Na+‐ion conductivity. Besides, DOL participates in the solvation sheath and weakens the chelation of Na+ by diglyme for facilitated desolvation. More importantly, it promotes concentrated electron cloud distribution around PF6− in the solvates and promotes their preferential decomposition. A desired inorganic‐rich SEI is generated with compositional uniformity, high ionic conductivity, and high Young's modulus. Consequently, a record‐high Coulombic efficiency over 99.9% is achieved at an ultralow temperature of −55 °C, and a 1 Ah capacity pouch cell of initial anode‐free sodium metal battery retains 95% of the first discharge capacity over 100 cycles at −25 °C. This study thus provides new insights for formulating electrolytes toward increased Na reversibility at LT.

Published: January 2024

AbstractFrequency‐selective surfaces (FSS) with flexible treatment can be employed in various applications. This paper develops a mechanically constructed flexible double‐layer adjustable FSS based on a 3D cross‐shaped kirigami structure design. Through mechanical stretching, the kirigami structure partly adhered to the ecoflex substrate enables this FSS to modulate the resonant frequencies of two filter bands synchronously. Meanwhile, the structural deformation triggered by mechanical stretching may function as a switch to adjust the filter band with a higher resonant frequency. According to the results of EM experiments and simulations, in the absence of stretching, the undeformed FSS with a double‐layer structure has two filter bands. Compared to the undeformed configuration, the stretching induces structural deformation, which results in apparent resonant frequency shifts of both the two filter bands and the contraction of the filter band with higher resonant frequency. A buckling model that has been theoretically, cumulatively, and experimentally proven is utilized to investigate the structural deformation of this FSS caused by stretching. It is convenient to switch flexible double‐layer adjustable FSS' deformation by mechanical method. This flexible double‐layer adjustable FSS offers a new design strategy for the application of FSS, paving the route for new developments in electromagnetic compatibility.

Published: January 2024

AbstractA previously undescribed aryne derived from a π‐extended biphenylene, 2,3‐didehydrobenzo[b]biphenylene, has been developed. The participation of this new aryne building block in [4+2] and palladium‐catalyzed [2+2+2] cycloaddition reactions has been applied to the synthesis of a variety of polycyclic conjugated hydrocarbons (PCHs) with appealing structures which combine (aromatic) benzene and (antiaromatic) cyclobutadiene (CBD) rings. Among them, a family of unsubstituted (or barely substituted) CBD‐oligoacenes has been accessed by iterative Diels‐Alder reactions of the new aryne with furans and/or isobenzofurans, followed by deoxygenative aromatization of the resulting epoxy‐derivatives. The experimental and computational studies of the newly synthesized PCHs suggest an important degree of electron delocalization along the polycyclic skeleton, more pronounced in the linearly fused derivatives. The computed ACID plots reveal clockwise current density vectors at the peripheral bonds, originating from the σ contributions of the antiaromatic cyclobutadiene rings.

Published: January 2024

AbstractThis research presents a method for the oxidative selenylation and thiolylation of Morita‐Baylis‐Hillman adducts through constant‐current electrolysis in an undivided cell at room temperature. The reaction enables direct production of trisubstituted (Z)‐allyl aryl selenides and sulfides with yields of 27–98%. A wide variety of different functionalities are well tolerated under these reaction conditions. This strategy could be carried out on gram scale and several synthetic transformations were accomplished for the construction of other allyl selenide derivatives. Control experiments and mechanistic studies indicate a radical or an ionic addition pathway for this electrochemical transformation.

AbstractEcofriendly supercapacitors (SCs) are fabricated with graphene electrodes printed on recycled‐plastics and utilized seawater as electrolyte. Those devices produced an energy density and capacitance of 50.4 Wh kg−1 and 250.4 F g−1, respectively. Later, a mixture of Bi─Mg─Fe─O (BMO) oxides is added to the SC electrodes and the capacitance of the devices increased up to 209%. Subsequently, SC electrodes are recovered from used/tested devices and utilized as “seed mats” to grow bean plants. For this purpose, pinto bean seeds are wrapped with recycled SC electrodes and later subjected to a germination treatment together with control seeds. The germination parameters are calculated from the bean plants and found that: 1) 100% of the seeds initially wrapped with the SC electrodes germinated, in contrast, only 88.9% of the control seeds germinated and 2) The bean plants grown with the seed mats has the longest roots/shoots. This occurred because the seed mats have Mg/Fe micronutrients on their surface as well as OH/COOH groups (coming from the seawater), which promote the germination and growth of bean plants. The results of this research demonstrated that SC electrodes coated with BMO can be used as a substrate to promote the growth of bean plants, which is of interest for sustainable agriculture.

Furthermore, an efficient hybrid off‐chip/on‐chip training method using the proposed device is presented. The results demonstrate a variation‐robust neuromorphic system, indicating the superiority of the proposed device.

Published: January 2024

AbstractThe 2D materials with both ferromagnetism and semiconducting properties are desirable for spintronics applications. Here, inspired by the successful synthesis of single‐layer CoCl, it predicts that Janus single‐layer CoClBr is a 2D intrinsic ferromagnetic semiconductor with a direct bandgap of 3.71 eV by first‐principles calculations. Single‐layer CoClBr exhibits an in‐plane magnetic anisotropic energy (MAE) of 542.25 eV per Co atom and a Curie temperature (T) of 89.49 K. Biaxial strain can effectively modulate its bandgap, MAE, and T, but will not change the ferromagnetic ground state. Compressive strain can increase the Curie temperature and switch the spin moment from in‐plane direction to out‐of‐plane direction. Tensile strain can enlarge the bandgap and introduce a direct‐to‐indirect bandgap transition in CoClBr. The MAE of CoClBr reaches 391.73 eV per Co atom and 1560.49 eV per Co atom at a compressive strain of ‐2% and a tensile strain of 5%, respectively. The tunable electronic and magnetic properties of Janus single‐layer CoClBr has potential application in low‐dimensional spintronics devices.

AbstractTopological gels possess structures that are cross‐linked only via physical constraints; ideally, no attractive intermolecular interactions act between their components, which yields interesting physical properties. However, most reported previous topological gels were synthesized based on supramolecular interlocked structures such as polyrotaxane, for which attractive intermolecular interactions are essential. Here, we synthesize a water‐soluble “molecular net” (MN) with a large molecular weight and three‐dimensional network structure using poly(ethylene glycol). When a water‐soluble monomer (N‐isopropylacrylamide) is polymerized in the presence of the MNs, the extending polymer chains penetrates the MNs to form an ideal topological MN gel with no specific attractive interactions between its components. The MN gels show unique physical properties as well a significantly high degree of swelling and high extensibility due to slipping of the physical cross‐linking. We postulate this method to yield a new paradigm in gel science with unprecedented physical properties.
