Published: February 2022

AbstractLack of sleep is common in adolescence, and represents an important threat to adolescents' well‐being, academic commitment, and general health. It also has significant behavioral consequences through an increased likelihood of interpersonal violence. Previous studies have demonstrated an association between aggressive behavior and lack of sleep, but the psychological mediators remain completely unexplored. Grounded in the General Aggression Model, we investigated the affective pathway as one of the potential mechanisms linking lack of sleep and aggression. We hypothesized and showed that psychological distress is an intermediary phenomenon linking lack of sleep and physical aggression. Based on a school sample of 11,912 participants (median age: 14.5), we observed that 23.7% of the young people admitted having been involved in physical fighting on one or more occasions, and that 25.81% were in sleep debt when referred for medical assessment. We analyzed the relationship between sleep duration and physical fighting and the mediating link of psychological distress by performing multiple regressions in the components' paths. The results showed that the adolescents' amount of sleep appeared to be a significant predictor of physical fighting, and that this relationship was partially mediated by psychological distress. These results are consistent with the General Aggression Model, and represent the first empirical confirmation that psychological distress symptoms partially mediate the connection between lack of sleep and physical aggression.

AbstractThe rapid proliferation of online multiplayer games has opened a new avenue for aggressive behaviors such as hostile communication, sabotaging, and griefing. The present investigation explores the prevalence, perception, risk factors, and consequences of victimization in toxic behaviors. A total of 2097 Hungarian gamers (88.5% male, Mage = 26.2 years, SD = 6.8) completed an online questionnaire. Most (66%) were victims of such incidents in the past year, and gamers considered the problem of toxic behaviors as severe. Younger gamers who spent more time playing competitive videogames (especially multiplayer online battle arena and shooter games) were more likely to experience toxic behaviors from others. Repeatedly victimized gamers reported more symptoms of depression and problematic videogame use, while victim/perpetrators expressed higher anxiety and anger rumination. These results highlight the importance of cultivating prosocial group norms in gamers to improve safety of online multiplayer environments.
Evaluation of radiation dose to pediatric models from whole body PET/CT imaging

Published: February 2022

AbstractPositron emission tomography (PET)/computed tomography (CT) is a well‐known modality for the diagnosis of various diseases in children and adult patients. On the other hand, younger patients are more radiosensitive than adults, so there are concerns about the level of ionizing radiation exposure in pediatric whole body PET/CT imaging. In this regard, comprehensive specific radiation dosimetry for whole body PET/CT imaging is highly desired for different ages, sizes, and shapes. Therefore, in this study, organ absorbed doses were evaluated for pediatric voxel models from 4 to 14 years old and compared with those of ICRP phantoms. Monte Carlo calculation was performed to evaluate S‐value, absorbed dose, and effective dose from 18F‐FDG radiotracers and whole body CT scan for different computational models, including 4‐ to 14‐year‐old phantoms. The results showed that the S‐value and, therefore, absorbed dose of 18F‐FDG strongly depended on the phantom anatomy. These variations were justified by the distance between source and target organs. Moreover, on average, the absorbed doses from whole body CT scans were 13.5 times lower than those from 18F‐FDG for all organs. According to the results, various anatomies and ages should be considered for accurate dose evaluation. These data can be used for specific risk assessment of the pediatric population in clinical nuclear imaging.

Published: February 2022

AbstractCarbon nanotubes (CNTs) buckypaper has shown extraordinary promise for freestanding supercapacitor electrode, but is usually limited by its extremely poor mechanical performance, which is due to the discrete nature of CNTs and rather low packing density. Meanwhile, manipulating the trade‐off between mechanical and electrochemical properties has not yet been realized for buckypaper electrode. Herein, a major breakthrough in optimizing the trade‐off between mechanical performance and compact capacitive delivery for porous buckypaper electrode is demonstrated by using aramid nanofibers (ANFs). Tailoring the microstructure of buckypaper framework by ANFs achieves 6.5‐ and 24.4‐times improvements in strength and toughness, respectively, without significantly sacrificing the volumetric capacitance (only 15.1% decline). Realizing such optimal integration of mechanical and capacitive properties represents a substantial step towards the practically feasible CNTs‐based structural electrodes. Further loading MnO2 conformal coating enables the freestanding electrode to deliver a superior volumetric capacitance of 155.5 F cm−3 while retaining the robust mechanical performance, which is impossible for conventional buckypaper or CNTs‐based bulk electrodes. The maximized structure‐function relationship achieved in this work validates the feasibility of reinforcing buckypaper electrode by ANFs, which may revolutionize the fabrication of advanced CNTs‐based supercapacitor electrodes, and offer a bright avenue for designing multifunctional structural composites.

AbstractMonolithic perovskite/organic tandem solar cells have attracted increasing attention due to their potential of being highly efficient while compatible to facile solution fabrication processes. One of the limiting factors for improving the performance of perovskite/organic tandem cells is the lack of wide‐bandgap perovskites with suitable bandgap, film quality, and optoelectronic properties for front cells. In addition, the development of low‐bandgap organic bulk‐heterojunction (BHJ) rare cells with extended absorption in the infrared range is also critical for improving tandem cells. This work has carefully optimized mixed halide wide‐bandgap perovskite (MWP) films by introducing a small amount of formamidinium (FA+) cations into the basic composition of MA1.06PbI2Br(SCN)0.12, which provides an effective means to modulate the crystallization properties and phase stability of the films. At optimized conditions, the MA0.96FA0.1PbI2Br(SCN)0.12 forms high‐quality films with grain boundaries homogeneously passivated by PbI2, leading to a reduction in defect states and an enhancement in phase stability, enabling the fabrication of perovskite solar cells with a power conversion efficiency(PCE) of 17.4%. By further integrating the MWP front cell with an organic BHJ (PM6:CH1007) rare cell composed of a nonfullerene acceptor with absorption extended to 950 nm, a tandem cell with PCE over 21% is achieved.

AbstractSingle‐crystalline micro‐/nanostructures based on organic stimulus‐responsive materials have attracted wide interests for their unique functional roles in various photonic applications including optical wave guiding, optical vapor sensing, and miniaturized lasing. Yet one imminent challenge is to pattern micro‐/nanostructured organic 1D arrays with controlled geometry, precise alignment, and pure crystallographic orientation owing to the uncontrollable dewetting dynamics in the solution processes. Herein, a smart assembly method is employed to regulate a confined crystallization of organic molecules. Sensitive, stable, and reproducible optical 1D‐array vapor sensors can detect the alkaline and acidic vapors based on the proton transfer process. As‐fabricated vapor sensors based on organic 1D arrays also selectively identify four similar amine vapors. Meanwhile, based on these 1D microstructure arrays, high‐performing Fabry–Pérot resonators with deep‐red laser emission, a low lasing threshold of 0.31 µJ, and high quality factor Q (≈2243) are realized. Owing to these multiple functions, organic microwire arrays not only provide intrinsic insight into optical vapor sensing but also offer guidance for the development of miniaturized lasers with specific functionalities, which show considerable potential in multifunctional photonic integrated circuits.

Published: February 2022

AbstractOptoelectronic synaptic devices, which combine the functions of photosensitivity and information processing, are essential for the development of artificial visual perception systems. Nevertheless, improving the paired pulse facilitation (PPF) index of optoelectronic synaptic devices, which is an urgent problem in the construction of high‐precision artificial visual perception systems, has received less attention so far. Herein, a light‐stimulated synaptic transistor (LSST) device with an ultra‐high PPF index (≈196%) is presented by introducing an ultra‐thin carrier regulator layer hexagonal boron nitride (h‐BN) into a classic graphene‐based hybrid transistor frame (graphene/CsPbBr3 quantum dots). Crucially, analysis of the rate‐limiting effect of h‐BN on photogenerated carriers reveals the mechanism behind the LSST ultra‐high PPF index. Furthermore, a two‐layer artificial neural network connected by LSST devices demonstrate ≈91.5% recognition accuracy of handwritten digits. This work provides an effective method for constructing artificial visual perception systems using a hybrid transistor frame in the future.

Published: February 2022

AbstractSonodynamic therapy is a noninvasive treatment method that generates reactive oxygen species (ROS) triggered by ultrasound, to achieve oxidative damage to tumors. However, methods are required to improve the efficiency of ROS generation and achieve continuous oxidative damage. A ternary heterojunction sonosensitizer composed of Bi@BiO2−x@Bi2S3‐PEG (BOS) to achieve thermal injury‐assisted continuous sonodynamic therapy for tumors is prepared. The oxygen vacancy in BOS can capture hot electrons and promotes the separation of hot carriers on the bismuth surface. The local electric field induced by localized surface plasmon resonance also contributes to the rapid transfer of electrons. Therefore, BOS not only possesses the functions of each component but also exhibits higher catalytic activity to generate ROS. Meanwhile, BOS continuously consumes glutathione, which is conducive to its biodegradation and achieves continuous oxidative stress injury. In addition, the photothermal conversion of BOS under near‐infrared irradiation helps to achieve thermal tumor damage and further relieves tumor hypoxia, thus amplifying the sonodynamic therapeutic efficacy. This process not only provides a strategy for thermal damage to amplify the efficacy of sonodynamic therapy, but also expands the application of bismuth‐based heterojunction nanomaterials as sonosensitizers in sonodynamic therapy.
Alternate Storage of Opposite Charges in Multisites for High‐Energy‐Density Al–MOF Batteries

Published: February 2022

AbstractThe limited active sites of cathode materials in aluminum‐ion batteries restrict the storage of more large‐sized Al‐complex ions, leading to a low celling of theoretical capacity. To make the utmost of active sites, an alternate storage mechanism of opposite charges (AlCl4− anions and AlCl2+ cations) in multisites is proposed herein to achieve an ultrahigh capacity in Al–metal–organic framework (MOF) battery. The bipolar ligands (oxidized from 18π to 16π electrons and reduced from 18π to 20π electrons in a planar cyclic conjugated system) can alternately uptake and release AlCl4− anions and AlCl2+ cations in charge/discharge processes, which can double the capacity of unipolar ligands. Moreover, the high‐density active Cu sites (Cu nodes) in the 2D Cu‐based MOF can also store AlCl2+ cations for a higher capacity. The rigid and extended MOF structure can address the problems of high solubility and poor stability of small organic molecules. As a result, three‐step redox reactions with two‐electron transfer in each step are demonstrated in charge/discharge processes, achieving high reversible capacity (184 mAh g−1) and energy density (177 Wh kg−1) of the optimized cathode in an Al–MOF battery. The findings provide a new insight for the rational design of stable high‐energy Al–MOF batteries.

Published: February 2022

AbstractMany medical equipment, such as tubes, lenses, and disposable plastic slides, require improved wettability to perform properly with physiological fluids and tissues. The authors proposes the regeneration of silk cocoons into insoluble and flexible regenerated silk fibroin (SF) films allowed for the development of novel materials with distinct and convincing characteristics. The SF films with glycerol modifications are created using a casting/solvent evaporation technique to provide a flexible and optically transparent hydrophilic coating. Fourier‐transformed infrared spectroscopy and wide‐angle X‐ray diffraction reveal a structural shift in glycerol‐induced SF films, where the random coil and helical structure content reduce while the β‐sheet structure increases significantly. All of the proposed SF films have an outstanding transmission of approximately 90% in the visible range and a UV‐shield characteristic. Tensile tests reveal that glycerol‐plasticized SF films are soft and extremely flexible, with a high Young's modulus and moderate tensile strength. The adhesion strength of the SF films is assessed as 5B at 10–20% wt of glycerol, suggesting outstanding adhesion strength on the silanized glass surface. At 30% w/w glycerol, the SF film has the greatest swelling ratio of 95.3 ± 0.5% and the lowest water contact angle of 23.2°.

AbstractDirect and ultrasensitive detection of nanoscale objects is of great importance for materials science and biomedical application. Here, a printed single nanoparticle array‐based coloration biochip is developed for direct visualizing nanoscale objects with the microscopy image. Arising from the scattering cross section induced Mie scattering enhancement, the color change of nanoparticles with/without viruses can be observed with a conventional optical microscope. The scattering light from single nanoparticle has the size‐dependent characteristics of wavelength and intensity variation, allowing for optically detecting nanoscale virus. By comparing optical images before and after attaching viruses, quantitative detection can be achieved with the virus concentrations from 1.0 × 102 to 1.0 × 106 PFU mL–1 and a detection limit of 1.0 × 102 PFU mL–1. The antibody‐modified array can specifically recognize influenza viruses in 15 min. The result provides a promising approach to detect diverse biological samples, including protein, exosomes, and platelet microparticle.

AbstractAcute kidney injury (AKI) is a complex clinical disorder associated with poor outcomes. Targeted regulation of the degree of inflammation has been a potential strategy for AKI management. Macrophages are the main effector cells of kidney inflammation. However, macrophage heterogeneity in ischemia reperfusion injury induced AKI (IRI‐AKI) remains unclear. Using single‐cell RNA sequencing of the mononuclear phagocytic system in the murine IRI model, the authors demonstrate the complementary roles of kidney resident macrophages (KRMs) and monocyte‐derived infiltrated macrophages (IMs) in modulating tissue inflammation and promoting tissue repair. A unique population of S100a9hiLy6chi IMs is identified as an early responder to AKI, mediating the initiation and amplification of kidney inflammation. Kidney infiltration of S100A8/A9+ macrophages and the relevance of renal S100A8/A9 to tissue injury is confirmed in human AKI. Targeting the S100a8/a9 signaling with small‐molecule inhibitors exhibits renal protective effects represented by improved renal function and reduced mortality in bilateral IRI model, and decreased inflammatory response, ameliorated kidney injury, and improved long‐term outcome with decreased renal fibrosis in the unilateral IRI model. The findings support S100A8/A9 blockade as a feasible and clinically relevant therapy potentially waiting for translation in human AKI.

Published: February 2022

AbstractCatheters integrated with microcoils for electromagnetic steering under the high, uniform magnetic field within magnetic resonance (MR) scanners (3–7 Tesla) have enabled an alternative approach for active catheter operations. Achieving larger ranges of tip motion for Lorentz force‐based steering have previously been dependent on using high power coupled with active cooling, bulkier catheter designs, or introducing additional microcoil sets along the catheter. This work proposes an alternative approach using a heat‐mitigated design and actuation strategy for a magnetic resonance imaging (MRI)‐driven microcatheter. A quad‐configuration microcoil (QCM) design is introduced, allowing miniaturization of existing MRI‐driven, Lorentz force‐based catheters down to 1‐mm diameters with minimal power consumption (0.44 W). Heating concerns are experimentally validated using noninvasive MRI thermometry. The Cosserat model is implemented within an MR scanner and results demonstrate a desired tip range up to 110° with 4° error. The QCM is used to validate the proposed model and power‐optimized steering algorithm using an MRI‐compatible neurovascular phantom and ex vivo kidney tissue. The power‐optimized tip orientation controller conserves as much as 25% power regardless of the catheter's initial orientation. These results demonstrate the implementation of an MRI‐driven, electromagnetic catheter steering platform for minimally invasive surgical applications without the need for camera feedback or manual advancement via guidewires. The incorporation of such system in clinics using the proposed design and actuation strategy can further improve the safety and reliability of future MRI‐driven active catheter operations.

Published: February 2022

AbstractIn this work, a scalable and rapid process is developed for creating a low‐cost humidity sensor for wireless monitoring of moisture levels within packaged goods. The sensor comprises a moisture‐sensitive interdigitated capacitor connected to a planar spiral coil, forming an LC circuit whose resonant frequency is a function of environmental humidity. The sensor is fabricated on a commercially available metallized parchment paper through selective laser ablation of the laminated aluminum (Al) film on the parchment paper substrate. The laser ablation process provides a unique one‐step patterning of the conductive Al layer on the paper while simultaneously creating high surface area Al2O3nanoparticles within the laser‐ablated regions. The intrinsic humidity‐responsive characteristics of the laser‐induced Al2O3nanostructures provide the wireless sensor with a tenfold higher sensitivity to humidity than a similar LC resonant sensor prepared by conventional photolithography‐based processes on FR‐4 substrates. The frequency change of the sensor is observed to be a linear function within the range of 0−85% RH, providing an average sensitivity of −87 kHz RH−1with good repeatability and stable performance. Furthermore, the employment of scalable laser fabrication processes using commercially available inexpensive materials renders these technologies viable for roll‐to‐roll manufacturing of low‐cost wireless sensors for smart packaging applications.

AbstractWith the unique mimicry of the sensory experiences of meats, the plant‐based meat alternatives (PBMA) appeal to consumers outside the traditional vegetarian demographics. This study analyzes market expenditure data from 2017 to 2020 to evaluate the demand for PBMA in relation to meats. Results show that PBMA is a complement for beef and pork while a substitute for chicken, turkey, and fish. Although the current market demand for PBMA is still incomparable with meats, the growth of PBMA sales is significant. This study sheds light on marketing strategies and policies toward the future of PBMA and the fresh meat sector.
