AbstractAimWith the increasing number of older people worldwide, dentists have more opportunities to manage patients whose oral health requires attention. Such patients often need to undergo minor dental surgery to restore their oral function; however, they usually experience post‐treatment complications that directly reduce their quality of life. This study aimed to comprehensively evaluate the frequency of complications occurring after minor dental surgery and identify predictors of delayed healing (one of the most frequent complications) among patients aged over 65 years.MethodsPatients who visited the Department of Oral Diagnosis and Medicine at Hokkaido University Hospital from 2015 to 2022 were selected and classified into the non‐delayed (n = 87) and delayed (n = 19) healing groups. The clinical backgrounds of these patients were compared between the two groups.ResultsAmong 106 patients aged over 65 years, delayed healing (17.9%) was the most frequent complication after minor dental surgery. Serum albumin levels (odds ratio: 10.0; 95% confidence interval: 2.15–46.6) significantly differed between the delayed and non‐delayed healing groups. Multivariate logistic regression analysis revealed that a serum albumin level of <3.5 g/dl (odds ratio: 10.1; 95% confidence interval: 1.83–56.2) was significantly associated with delayed healing.ConclusionThis study proposed that serum albumin level is a potential predictor of delayed healing in patients aged over 65 years who undergo minor dental surgery. In clinical practice, dentists are required to evaluate and improve nutritional status of older patients even before minor dental surgery.

Published: April 2024

AbstractThis work aims to prepare new poly(ionic liquid)s (PILs) and use them for crude oil emulsion separation (EES). PILs were synthesized by an opening ring reaction of hexadecylsuccinic anhydride (HAS) using polyethyleneimine branched MW 600 (PEI) and triethylenetetramine (TTA) in a one‐step procedure, obtaining PILs, HSPI‐PIL, and HSTA‐PIL, respectively. Chemical structure, interfacial tension, aggregate size, and thermal behavior were verified using several techniques. The efficiency of HSPI‐PIL and HSTA‐PIL toward EES was explored using different parameters, including water content (WC), demulsifier concentration, temperature, and pH value. The results indicated that EES proportionally increased with increased WC and temperature. The data also revealed that increased demulsifier concentration improved EES at low WC, for example, 10% and 30%; however, this parameter showed no significant effect with crude oil emulsion containing high WC, for example, 50%. Furthermore, HSPI‐PIL and HSTA‐PIL gave the maximum EES values at a pH of 7, while they decreased in acidic and basic mediums.

Published: April 2024

AbstractTo further increasing the toughness performance of thermoset resins without sacrificing their other properties is still a challenge task. In this study, the soft core–soft shell nanoparticles based on polydopamine‐modified cellulose nanocrystals (P‐CNC) were synthesized and seamlessly integrated with Bisphenol A‐aniline benzoxazine (BA‐a). Notably, the results underscore the remarkable impact of a mere 0.2 wt% of P‐CNC on BA‐a, boosting the impact strength of the modified system to 19.5 kJ/m2. This achievement represents a substantial 140.7% increase compared with pure polybenzoxazine. Moreover, the flexural strength reaches 133.4 MPa, surpassing pure polybenzoxazine by 16.2%. And the modified system exhibits a 10% weight loss temperature (Td10) at 321.7°C, accompanied by a char yield of 27.6%. This holistic approach results in a notable enhancement of the toughness performance while concurrently maintaining the flexural strength and the thermal stability of the modified system. Consequently, the integration of soft core–soft shell nanoparticles emerges as a promising strategy for enhancing thermoset resin properties without undermining their existing exceptional attributes.Highlights
The core–shell nanoparticles were made by dopamine and cellulose nanocrystals.
The core–shell nanoparticles can enhance the toughness of polybenzoxazine.
Nanoparticle‐matrix interactions and deformation led to improved properties.

AbstractBackgroundThe polysomnography (PSG) is the gold‐standard for obstructive sleep apnea (OSA) syndrome diagnosis and assessment under positive airway pressure (PAP) therapies in children. Recently, an innovative digital medicine solution, including a mandibular jaw movement (MJM) sensor coupled with automated analysis, has been validated as an alternative to PSG for pediatric application.ObjectiveThis study aimed to assess the reliability of MJM automated analysis for the assessment of residual apnea/hypopnea events during sleep in children with OSA treated with noninvasive ventilation (NIV) or continuous PAP (CPAP).MethodsIn this open‐label prospective non‐randomized multicentric trial, we included children aged from 5 to 18 years with a diagnosis of severe OSA. The children underwent in‐laboratory PSG with simultaneous MJM monitoring and at‐home recording with MJM monitoring 3 months later. Agreement between PSG and MJM analysis in measuring the residual apnea‐hypopnea index (AHI) was evaluated by the Bland−Altman method. The treatment effect on residual AHI was estimated for both PSG and MJM analysis.ResultsFifteen (60% males) children were included with a median age of 12 years [interquartile range 8−15]. Two (17%) were ventilated with NIV and 13 (83%) with CPAP. There was a good agreement between MJM‐AHI and PSG‐AHI with a median bias of −0.25 (95% CI: −3.40 to +2.04) events/h. The reduction in AHI under treatment was consistently significant across the three measurement methods: in‐laboratory PSG and MJM recordings in the laboratory and at home.ConclusionAutomated analysis of MJM is a highly reliable alternative method to assess residual events in a small population treated with PAP therapies.

AbstractBackgroundThis study explores the linkage between the Measurement of Environmental Quality (MQE) and the International Classification of Functioning, Disability, and Health (ICF). Stemming from the Human Development Model—Disability Creation Process (HDM‐DCP), MQE enhances understanding of how environmental quality impacts disability development across diverse socio‐cultural contexts. Integrating MQE with ICF expands the perspective on disability formation beyond HDM‐DCP, encompassing ICF's functioning approach.ObjectiveTo link the MQE with the concepts and categories of the ICF.MethodsTwo health professionals with adequate taxonomic knowledge of the ICF performed the initial linkage, which was based on updated standardized rules considering all hierarchical levels of the ICF. Linkage agreement between the first two assessors was measured using the Kappa (k) coefficient and respective 95% confidence intervals. In the absence of a consensus between the two assessors (k > 0.60), a third assessor was consulted to make the arbitrary decision of the final categories linked to the MQE.ResultsInsufficient agreement between the two assessors was found for the linkage process (k = 0.52;p < 0.001), requiring the final decision from the third assessor. At the end of the process, 26 ICF categories were linked to the main concepts (MC) measured by the 26 items of the short version of the MQE. Ten ICF categories were linked to the additional concepts (AC) measured by the MQE. Moreover, the MQE addresses the five domains of the ICF component “environmental factors,” with a predominance of the “services, systems and policies” domain (MC = 45.8% and AC = 40%).ConclusionThe linkage of the concepts measured by the MQE to ICF categories enabled mapping the content of the MQE, identifying it as a promising tool for measuring environmental factors in accordance with ICF percepts.

AbstractThe authors present the clinical case of a 59‐year‐old female patient with a history of peripheral desaturation, which was detected in the perioperative period 4 years earlier. She reported exertional dyspnea, quantified as grade 2 on the Modified Medical Research Council (mMRC) Dyspnea Scale (walks slower than people of the same age because of dyspnea or has to stop for breath when walking at her own pace), and morning cough with mucoid sputum and denied platypnea, epistaxis, telangiectasias and hemoptysis. A computed chest tomography scan revealed a contrast‐enhanced lesion on the right upper lobe with an afferent and two efferent vessels compatible with pulmonary arteriovenous malformation. The transesophageal echocardiogram revealed an important right–left shunt compatible with arteriovenous fistula in the pulmonary circulation. An angiography confirmed the diagnosis and a selective embolization of the afferent artery was performed with resolution of symptoms.

AbstractNK/T‐cell lymphoma (NKTCL) is a highly aggressive malignant tumour with a very poor prognosis, which often poses diagnostic difficulties due to the non‐specificity of its clinical presentation. NK/T‐cell lymphoma with eosinophilic hyperplasia syndrome is extremely rare. This article describes a patient with NKTCL misdiagnosed as vasculitis who presented with sinusitis, abdominal pain, anorexia, and lung shadows. Additionally, the patient exhibited extremely high eosinophilia levels, which led to a further misdiagnosis of eosinophilic granuloma. We describe the clinical features, diagnostic methods and differential diagnosis of lymphoma and highlights the importance of a multidisciplinary approach in accurate diagnosis and treatment.

AbstractIt is important to obtain real‐time leaf density of fruit‐tree canopies for the precision spray control of plant‐protection robots. However, conventional detection techniques for the characteristics of fruit‐tree canopies cannot acquire the canopy internal information, which may provide an unsatisfactory accuracy of detection of leaf densities. This paper proposes a method for estimating canopy leaf density of fruit trees based on wind‐excited audio. A wind‐exciting implement was used to force fruit‐tree canopy leaves vibrating to produce audio. Then, some correlation analysis methods were used to extract key characteristic parameters of wind‐excited audio that were significantly correlated with leaf density. Finally, based on the data set of wind‐excited audio, a few machine‐learning methods were used to develop leaf‐density estimation models. Test results showed that: (1) there were five key feature parameters of wind‐excited audio that were significantly correlated with leaf density: the short‐time energy, spectral centroid, the frequency average energy, the peak frequency, and the standard deviation of frequency. (2) the estimation model of leaf density developed based on backpropagation neural network for fruit‐tree canopy showed the optimal estimation results, which can achieve the estimation of leaf density of fruit‐tree canopies accurately. The overall correlation coefficient (R) of the estimation model was more than 0.84, the root‐mean‐square error was less than 0.73 m2 m−3, and the mean absolute error was less than 0.53 m2 m−3. This study is expected to provide a technical solution for the leaf‐density detection of fruit‐tree canopies of plant‐protection robots.

AbstractThe reaction of bis‐2‐(methylthiocarbonothioyl)hydrazone with the appropriate hydrazonoyl halides in 1,4‐dioxane in the presence of triethylamine at reflux yielded a novel series of bis(1,3,4‐thiadiazoles) linked to a thieno[2,3‐b]thiophene core. The reaction of the appropriate α‐ketohydrazonoyl halides or α‐haloketones with the corresponding bis(2‐carbamothioylhydrazone) in ethanol at reflux in the presence of a few drops of triethylamine produced good yields of novel bis‐thiazoles linked to the thieno[2,3‐b]thiophene core as novel hybrid molecules. Elemental analyses and spectral data were used to determine the structures of the novel compounds. The antibacterial activity of newly synthesized compounds was evaluated. The MIC determination using resazurin was studied for the most reactive compounds. The pharmacokinetic properties were evaluated by in silico ADMET analysis.

Published: April 2024

AbstractGiven that the ion‐exchange membrane takes up more than 30% of redox flow battery (RFB) cost, considerable cost reduction is anticipated with the membrane‐free design. However, eliminating the membrane/separator would expose the membrane‐free RFBs to a higher risk of short‐circuits, and the dendrite growth may aggravate this issue. The current strategy based on expanding distances between electrodes is proposed to address short‐circuit issues. Nevertheless, this approach would decrease the energy efficiency (EE) and could not restrain dendrite growth fundamentally. Herein, an inexpensive and electron‐insulating boron nitride nanosheets (BNNSs)‐Nylon hybrid interlayer (BN/Nylon) is developed for general membrane‐free RFBs to achieve “near‐zero distance” contact between electrodes. And the Lewis acid sites (B atoms) in BNNS can interact with the Lewis base anions in electrolytes, enabling a reduced Pb2+concentration gradient. Additionally, the ultrahigh thermal conductivity and mechanical strength of BNNSs promote the uniform plating/stripping process of Pb and PbO2. Compared with conventional soluble lead RFBs, introducing BN/Nylon interlayers boosts EE by ≈38.2% at 25 mA cm−2, and extends the cycle life to 100 cycles. This innovative strategy premieres the application of the BN/Nylon interlayer concept, offering a novel perspective for the development of general membrane‐free RFBs.

AbstractLithium–sulfur (Li–S) batteries with high theoretical energy density (2600 Wh kg−1) are considered to be one of the most promising secondary batteries. However, the practical application of Li–S batteries is limited by the polysulfides shuttling and unstable lithium metal anodes. Herein, an asymmetric separator (CACNM@PP), composed of Co–Ni/MXene (CNM) on the cathode and Cu–Ag/MXene (CAM) on the anode for high‐performance Li–S batteries is reported. For the cathode, CNM provides a synergistic effect by integrating Co, Ni, and MXene, resulting in strong chemical interactions and fast conversion kinetics for polysulfides. For the anode, CAM with abundant lithiophilicity active sites can lower the nucleation barrier of Li. Moreover, LiCl/LiF layers are generated in situ as an ion conductor layer during charging and discharging, inducing a uniform deposition of Li. Therefore, the assembled cells with the CACNM@PP separators harvest excellent electrochemical performance. This work provides novel insights into the development of commercially available high‐energy density Li–S batteries with asymmetric separators.

Published: April 2024

AbstractIn this work, Pt3Fe nanoparticles (Pt3Fe NPs) with the ordered internal structure and Pt‐rich shells surrounded by plenty of Fe single atoms (Fe SAs) as active species (Pt3Fe NP‐in‐Fe SA) loaded in the carbon materials are successfully fabricated, which are abbreviated as island‐in‐sea structured (IISS) Pt3Fe NP‐in‐Fe SA catalysts. Moreover, the synergistic effect of O‐bridging between Pt3Fe NPs and Fe SAs, and the ordered internal structured Pt3Fe NPs with Pt‐rich shells of an optimal thickness contributes to the achievement of the local acidic environments on the surfaces of Pt3Fe NPs in the alkaline hydrogen evolution reaction (HER) and the enhancement of the desorption rate of *OH intermediate in the acidic oxygen reduction reaction (ORR). In addition, the electronic interactions between Pt3Fe NPs and dispersed Fe SAs cannot only provide efficient electrons transfer, but also prevent the aggregation and dissolution of Pt3Fe NPs. Furthermore, the overpotential and the half wave potential of the as‐prepared IISS Pt3Fe NP‐in‐Fe SA catalysts toward the alkaline HER and toward the acidic ORR are 8 mV at a current density of 10 mA cm−2 and 0.933 V, respectively, which is 29 lower and 86 mV higher than those (37 mV and 0.847 V) of commercial Pt/C catalysts.

Published: April 2024

AbstractThe challenges of Lithium‐carbon dioxide (Li‐CO2) batteries for ensuring long‐term cycling stability arise from the thermodynamically stable and electrically insulating discharge products (e.g., Li2CO3), which primarily rely on their interaction with the active materials. To achieve the optimized intermediates, the bifunctional electron donor–acceptor (D–A) pairs are proposed in cathode design to adjust such interactions in the case of B–O pairs. The inclusion of BC2O sites allows for the optimized redistribution of electrons via p–π conjugation. The as‐obtained DO–AB pairs endow the enhanced interactions with Li+, CO2, and various intermediates, accompanied by the adjustable growth mode of Li2CO3. The shift from solvation‐mediated mode into surface absorption mode in turn manipulates the morphology and decomposition kinetics of Li2CO3. Therefore, the corresponding Li‐CO2 battery got twofold improved in both the capacity and reversibility. The cycling prolongs exceed 1300 h and well operates at a wide temperature range (20–50 °C) and different folding angles (0–180°). Such a strategy of introducing electron donor–acceptor pairs provides a distinct direction to optimize the lifetime of Li‐CO2 battery from local structure regulation at the atomic scale, further inspiring in‐depth understandings for developing electrochemical energy storage and carbon capture technologies.

Published: April 2024

AbstractMarangoni actuators that are propelled by surface tension gradients hold significant potential in small‐scale swimming robots. Nevertheless, the release of “fuel” for conventional chemical Marangoni actuators is not easily controllable, and the single swimming function also limits application areas. Constructing controllable Marangoni robots with multifunctions is still a huge challenge. Herein, inspired by water striders, electricity‐driven strategies are proposed for a multifunctional swimming Marangoni robot (MSMR), which is fabricated by super‐aligned carbon nanotube (SACNT) and polyimide (PI) composite. The MSMR consists of a Marangoni actuator and air‐ambient actuators. Owing to the temperature gradient generated by the electrical stimulation on the water surface, the Marangoni actuators can swim controllably with linear, turning, and rotary motions, mimicking the walking motion of water striders. In addition, the Marangoni actuators can also be driven by light. Importantly, the air‐ambient actuators fabricated by SACNT/PI bilayer structures demonstrate the function of grasping objects on the water surface when electrically Joule‐heated, mimicking the predation behavior of water striders. With the synergistic effect of the Marangoni actuator and air‐ambient actuators, the MSMR can navigate mazes with tunnels and grasp objects. This research will provide a new inspiration for smart actuators and swimming robots.

Published: April 2024

Abstract2D materials‐based broadband photodetectors have extensive applications in security monitoring and remote sensing fields, especially in supersonic aircraft that require reliable performance under extreme high‐temperature conditions. However, the integration of large‐area heterostructures with 2D materials often involves high‐temperature deposition methods, and also limited options and size of substrates. Herein, a liquid‐phase spin‐coating method is presented based on the interface engineering to prepare larger‐area Van der Waals heterojunctions of black phosphorus (BP)/reduced graphene oxide (RGO) films at room temperature on arbitrary substrates of any required size. Importantly, this method avoids the common requirement of high‐temperature, and prevents the curling or stacking in 2D materials during the liquid‐phase film formation. The BP/RGO films‐based devices exhibit a wide spectral photo‐response, ranging from the visible of 532 nm to infrared range of 2200 nm. Additionally, due to Van der Waals interface of Schottky junction, the array devices provide infrared detection at temperatures up to 400 K, with an outstanding photoresponsivity (R) of 12 A W−1 and a specific detectivity (D*) of ≈2.4 × 109 Jones. This work offers an efficient approach to fabricate large‐area 2D Schottky junction films by solution‐coating for high‐temperature infrared photodetectors.
