AbstractBiomechanical energy harvesting shows great potential in the fields of smart electronics and biomedical Internet of Things. However, it is a significant challenge to develop a biomechanically driven energy harvester with high output power and fast charging as a sustainable power source for extended practical applications. Herein, an ultrahigh‐output triboelectric and electromagnetic hybrid generator (UHO‐TEHG) is developed to efficiently harvest biomechanical energy and provide self‐powered systems for numerous applications. The Halbach magnet array is used to concentrate additional magnetic flux in the coil and significantly enhance electromagnetic performance, while the novel poly(ethylene oxide) nanofibers enhance the triboelectric performance. Through the implementation of a mechanical spring‐mass model, and rational integration of electromagnetic and triboelectric generators, the UHO‐TEHG can provide an excellent output power of 1.02 W. Compared with existing mechanical energy harvesting devices, the fabricated device exhibits a much faster battery charging performance. Experimental results reveal remarkable performance related to biomechanical energy harvesting during walking, running, hiking, mountaineering, and self‐powered wireless human motion sensor. Real‐time charging of smartphones, smartwatches, Buds Live, and iTag via customized power management circuits is demonstrated. In addition, the fabricated UHO‐TEHG demonstrates the capability to power healthcare monitoring systems using a laser‐induced hierarchical carbon nanofiber‐based e‐tattoo sensor.

AbstractKasha's rule, which states that all exciton emissions occur from the lowest excited state and are independent of excitation energy, makes high‐energy excitons difficult to use and severely hinders the widespread applications of organic photoluminescent materials in the real world. For decades, scientists have tried to break this rule to unleash the power of high‐energy excitons, but only minimal progress has been achieved, with no rational guiding principles provided, and few applications developed. So far, breaking Kasha's rule has remained a purely academic concept. In this paper, we introduce a design principle for a purely organic anti‐Kasha system and synthesise a series of compounds based on the design rule. As predicted, these compounds all display evident S2 emissions in dilute solutions. In addition, we introduce a highly accurate (over 90%) convolutional neural network as an assistant for the classification of cells using anti‐Kasha luminogens, thereby providing a new application direction for anti‐Kasha systems.
Engineering the direct Z‐scheme systems over lattice intergrown ofMOF‐on‐MOFfor selectiveCO2photoreduction toCO

Published: September 2022

AbstractThe direct Z‐scheme provides a potential strategy for highly efficient CO2photoreduction, whereas the heterointerface contact resistance is significantly limited the interfacial electron transfer kinetic. Herein, we build the directional charge‐transfer channels in a direct Z‐scheme system over metal–organic frameworks (MOFs), that is, the lattice‐guided MOF‐on‐MOF hybrids, to facilitate CO2photoreduction. The heteroepitaxial lattice growth along thec‐axis of MIL‐88B(Fe) via the high‐activity (001) facet over the stable (111) facet of UiO‐66‐NH2. Theoretical calculations and experimental results provide direct evidence that engineering direct Z‐scheme of these MOFs hybrids can induce the electrons migration from UiO‐66‐NH2to the holes of MIL‐88B(Fe) by directional charge‐transfer channels owing to their lattice match. This can dramatically boost photocatalytic CO2‐to‐CO selectivity up to nearly 100%, with a rate of 2.26 μmol g−1 h−1. This work demonstrates that the efficiently selective CO2photoreduction processes can be achieved by engineering Z‐scheme via lattice intergrown of MOF hybrids strategy.
Hypothesis: Symbrachydactyly
Authors: Holmes Lewis B. , Nasri Hanah Z. 
Published: September 2022

AbstractThe term symbrachydactyly has been used for the phenotype of two or three short fingers or toes, hypoplasia of the middle and distal phalanges and variable syndactyly of the affected digits. Some clinicians have extended this diagnosis to include other phenotypes, specifically cleft hand, terminal transverse limb defects, hypoplasia of the thumb and fifth finger with nubbins for fingers 2, 3, and 4 and the hand deformity of the Poland anomaly. A malformations surveillance program can identify enough affected infants to characterize a phenotype. In the Active Malformations Surveillance Program in Boston (1972–2012) among 289,365 births, all infants and fetuses with structural abnormalities were identified from reading the examination findings by the pediatricians and pathologists and the results of diagnostic tests. Liveborn and stillborn infants were included, as well as fetuses from elective terminations because of anomalies identified in prenatal testing. We present the findings in 14 infants, all liveborn, who had symbrachydactyly of one or both hands (n = 12) or feet (n = 2). We suggest restricting the term symbrachydactyly to this single phenotype to improve counseling and to focus future research on identifying the cause(s).

Published: September 2022

AbstractCoumarins, due to their intense and persistent emission of fluorescence, structural flexibility, and excellent biocompatibility, have become a popular choice in developing new fluorescent chemosensors. Coumarins have long been used for sensing anions, cations, chemically reactive nitrogen, oxygen, sulfur‐containing species, and small molecules. They have also been shown to have applicability in imaging, biology, and medical research. Due to the widespread use and excellent biological activity, hundreds of such coumarin motifs have either been isolated from nature or synthesized in a laboratory. This review covers all the developments pertaining to the synthesis and use of coumarin for sensing a variety of metal ions (alkali, alkaline earth, transition, heavy, and noble metal ions). This comprehensive review includes an overview of the coumarin‐based chemosensor‘s pH limit, detection limit, and binding mode. A brief explanation of the stoichiometric ratio between metal and chemosensor moiety and the applicability of each chemosensor is also given.
Two‐Magnon Non‐Locality and Coherence Induced by an Open Microwave Cavity: Generation and Robustness
Authors: Mohamed A.‐B. A. , Eleuch H. 
Published: September 2022

AbstractThe generation and robustness of two‐magnon non‐locality and coherence dynamics induced by an open microwave field cavity are investigated in this work. The studied system consists of a two‐sublattice ferrimagnet coupled to a microwave field within an open cavity through its magnetic field component. The robustness of the two‐magnons non‐locality dynamics is analyzed using various non‐locality and coherence measures (namely, uncertainty‐induced non‐locality [UIN], maximal Bell function, and log‐negativity entanglement [L‐NE]) in the presence of the spontaneous emission and the electromagnetic‐wave dissipation. It is shown that photon‐magnon couplings, two‐magnon couplings, and dissipation all have an impact on the dynamical aspect of two‐magnon non‐locality and coherence. This work reveals that the two‐magnon non‐locality and coherence can be generated. For an initial maximal correlated two‐magnon state, the initial UIN non‐locality is shown to be more resilient than the maximum Bell function and log‐negativity. The amplitudes of the two‐magnon non‐locality quantifiers decline as a result of the two‐magnon coupling. The Bell non‐locality and L‐NE are reduced via spontaneous emission and dissipation, but the two‐magnon UIN‐coherence is preserved. These findings contribute to a better understanding of such dynamics and may shed light on measurement estimation in open quantum systems.

AbstractAn optimized approach to producing lattice‐matched heterointerfaces for electrocatalytic hydrogen evolution has not yet been reported. Herein, we present the synthesis of lattice‐matched Mo2C−Mo2N heterostructures using a gradient heating epitaxial growth method. The well lattice‐matched heterointerface of Mo2C−Mo2N generates near‐zero hydrogen‐adsorption free energy and facilitates water dissociation in acid and alkaline media. The lattice‐matched Mo2C−Mo2N heterostructures have low overpotentials of 73 mV and 80 mV at 10 mA cm−2 in acid and alkaline solutions, respectively, comparable to commercial Pt/C. A novel photothermal‐electrocatalytic water vapor splitting device using the lattice‐matched Mo2C−Mo2N heterostructure as a hydrogen evolution electrocatalyst displays a competitive cell voltage for electrocatalytic water splitting.
Pseudo‐heterolepticity in Low‐Symmetry Metal‐Organic Cages
Authors: Lewis James E. M. 
Published: September 2022

AbstractHeteroleptic metal‐organic cages, formed through integrative self‐assembly of ligand mixtures, are highly attractive as reduced symmetry supramolecular hosts. Ensuring high‐fidelity, non‐statistical self‐assembly, however, presents a significant challenge in molecular engineering due to the inherent difficulty in predicting thermodynamic energy landscapes. In this work, two conceptual strategies are described that circumvent this issue, using ligand design strategies to access structurally sophisticated metal‐organic hosts. Using these approaches, it was possible to realise cavity environments described by two inequivalent, unsymmetrical ligand frameworks, representing a significant step forward in the construction of highly anisotropic confined spaces.

AbstractSelective electrocatalytic oxidation of alcohols to value‐added aldehydes has attracted increasing attention. However, due to its higher reactivity than alcohol, the aldehyde is easily over‐oxidized to acid in alkaline electrolytes. Herein we realize the selective electrooxidation of alcohol to aldehyde on NiO by tuning the local microenvironment to salt out the aldehyde from the reaction system. The origin of the high selectivity was found to be the inhibition of the hydration of aldehydes, which is the result of the decreased alkalinity and the increased cation and substrate concentration. This strategy could salt out the aldehyde at the gas|electrolyte interface from the electrooxidation of alcohol with 100 % selectivity and be easily extended to other selective oxidation reactions, such as 5‐hydroxymethyl furfural (HMF) to 2,5‐furandicarboxaldehyde (DFF) and amine to an imine.

AbstractCarbon dioxide electroreduction (CO2RR) is a sustainable way of producing carbon‐neutral fuels. Product selectivity in CO2RR is regulated by the adsorption energy of reaction‐intermediates. Here, we employ differential phase contrast‐scanning transmission electron microscopy (DPC‐STEM) to demonstrate that Sn heteroatoms on a Ag catalyst generate very strong and atomically localized electric fields. In situ attenuated total reflection infrared spectroscopy (ATR‐IR) results verified that the localized electric field enhances the adsorption of *COOH, thus favoring the production of CO during CO2RR. The Ag/Sn catalyst exhibits an approximately 100 % CO selectivity at a very wide range of potentials (from −0.5 to −1.1 V, versus reversible hydrogen electrode), and with a remarkably high energy efficiency (EE) of 76.1 %.

AbstractObjectivesTo assess the inter methodological agreement of membrane septum (MS) length measurement and additive value for risk stratification of new pacemaker implantation (PMI) over the established predictors after transcatheter aortic valve replacement (TAVR).BackgroundRecent studies have suggested MS length and implantation depth (ID) as predictors for PMI after TAVR. However, the measurement of MS length is neither uniform nor validated in different cohort.MethodsWe retrospectively analyzed patients who underwent TAVR at five centers. The MS length was measured by two previously proposed methods (coronal and annular view method). Predictive ability of risk factors, including MS length and ID, for new PMI within 30 days after TAVR were evaluated.ResultsAmong 754 patients of study population, 31 patients (4.1%) required new PMI within 30 days of TAVR. There was a weak correlation (ρ = 0.47) and a poor agreement between the two methods. The ID and the difference between MS length and ID (ΔMSID), were independent predictors for new PMI, whereas MS length alone was not. Further, for predicting new PMI after TAVR, discrimination performance was not significantly improved when MS length was added to the model with ID alone (integrated discrimination improvement = 0, p= 0.99; continuous net‐reclassification improvement = 0.10, p= 0.62).ConclusionsExternal validity and predictive accuracy of MS length for PMI after TAVR were not sufficient to provide better risk stratification over the established predictors in our cohort. Moreover, the ID and ΔMSID, but not MS length alone, are predictive of future PMI after TAVR.

Published: September 2022

AbstractMixed transition metal oxides have emerged as promising electrode materials for electrochemical energy storage and conversion. To optimize the functional electrode properties, synthesis approaches allowing for a systematic tailoring of the materials’ composition, crystal structure and morphology are urgently needed. Here we report on the room‐temperature electrodeposition of a ternary oxide based on earth‐abundant metals, specifically, the defective cubic spinel ZnMnO3. In this unprecedented approach, ZnO surfaces act as (i) electron source for the interfacial reduction of MnO4− in aqueous solution, (ii) as substrate for epitaxial growth of the deposit and (iii) as Zn precursor for the formation of ZnMnO3. Epitaxial growth of ZnMnO3 on the lateral facets of ZnO nanowires assures effective electronic communication between the electroactive material and the conducting scaffold and gives rise to a pronounced 2‐dimensional morphology of the electrodeposit forming – after partial delamination from the substrate – twisted nanosheets. The synthesis strategy shows promise for the direct growth of different mixed transition metal oxides as electroactive phase onto conductive substrates and thus for the fabrication of binder‐free nanocomposite electrodes.

SummaryIn the past several years, a series of breakthrough research advancements have been achieved by leveraging wireless signals such as Wi‐Fi in various emerging applications, including healthcare, behavior recognition, positioning, and target detection. Compared to traditional human behavior sensing methods, Wi‐Fi signals human behavior sensing technology has many advantages, including non‐line‐of‐sight, sensor device‐free sensing, passive sensing, ease of deployment, and no need for lights. Data mining undoubtedly plays a critical role in making Wi‐Fi‐based human behavior detection intelligent enough to facilitate convenient services and environments. We study Wi‐Fi signals mining using the data mining process and review the developmental process of Wi‐Fi data mining. This covers the methods of Wi‐Fi data mining, including signal acquisition, preprocessing, feature extraction to training, and classification. We then propose WHSecurity, a whole home intrusion detection and tracking system that is based on all of the methods covered above. Finally, WHSecurity includes a deep learning‐based data mining process called multiview learning for the decision‐making on intrusion detection and tracking. Experimental outcomes show that the WHSecurity approach performs superior in terms of intrusion detection and tracking performance.

Published: September 2022

AbstractNonsteroidal anti‐inflammatory drugs represent one of the most popularly used classes of drugs. However, their long‐term administration is associated with various side effects including gastrointestinal ulceration. One of the major reasons of NSAIDs ulcerogenicity is direct damage of the epithelial lining cells by the acidic moieties present in many drugs. Another drawback for this acidic group is its rapid metabolism and clearance through Phase II conjugation. Three series of thiophene and thienopyrimidine derivatives were designed and synthesized as nonacidic anti‐inflammatory agents. In vivo testing of their analgesic activity indicated that compounds 2b and 7a‐d showed higher PI values than that of the positive control drugs, indomethacin and celecoxib. The latter compounds 2b and 7a‐d were subjected to further anti‐inflammatory activity testing where they showed comparable percentage edema inhibition to that of indomethacin and celecoxib. Compounds 2b, 7a, 7c, and 7d inhibited PGE2 synthesis by 61.10%–74.54% (71.47% for indomethacin, and 80.11% for celecoxib). The same compounds inhibited the expression of rat mPGES‐1 and cPGES3 by 74%–83% (77% for indomethacin, and 82% for celecoxib) and 48%–70% (62% for indomethacin, and 70% for celecoxib), respectively. The stability of the most active compound 2b in Nonenzymatic gastrointestinal fluids and in human plasma was tested. Additionally, studying the metabolic stability of compound 2b in S9 rat liver fraction showed that it displayed a slow in vitro clearance with half‐life time 1.5‐fold longer than indomethacin. The metabolites of 2b were predicted via UPLC‐MS/MS. In silico ADMET profiling study was also included.

Published: September 2022

AbstractMicroearthquakes accompanying shale gas recovery highlight the importance of exploring the frictional and stability properties of shale gouges. Aiming to reveal the influencing factors on fault stability, this paper explores the impact of mineral compositions, effective stress and temperature on the frictional stability of Longmaxi shale gouges in deep reservoirs located in the Luzhou area, southeastern Sichuan Basin. Eleven shear experiments were conducted to define the frictional strength and stability of five shale gouges. The specific experimental conditions were as follows: temperatures: 90–270°C; a confining stress: 95 MPa; and pore fluid pressures: 25–55 MPa. The results show that all five shale gouges generally display high frictional strength with friction coefficients ranging from 0.60 to 0.70 at the aforementioned experiment condition of pressures, and temperatures. Frictional stability is significantly affected by temperature and mineral compositions, but is insensitive to variation in pore fluid pressures. Fault instability is enhanced at higher temperatures (especially at >200°C) and with higher tectosilicate/carbonate contents. The results demonstrate that the combined effect of mineral composition and temperature is particularly important for induced seismicity during hydraulic fracturing in deep shale reservoirs.

Published: September 2022

AbstractRecently, dynamic wireless power transfer (DWPT) for battery electric vehicles has been actively studied because it can enhance their cruising range and reduce their charging time. An SS type WPT circuit is simpler and more efficient than a WPT circuit with a filter, such as an LCC type WPT circuit. By contrast, the leakage magnetic field generated by the harmonic current is a problem that needs to be addressed. The leakage magnetic field is limited by the Radio Act and the Ordinance for Regulating Radio Equipment in Japan. This study aims to reduce the leakage magnetic field generated by the harmonic current using a high‐frequency switching technology. The inverter and rectifier are operated using pulse width modulation (PWM) with a high carrier frequency. The effectiveness of the proposed method was experimentally verified using a GaN inverter and rectifier. As a result, the proposed method can drastically reduce the leakage magnetic field, especially, the magnetic field generated by the current harmonics of order greater than five.
