Authors: Chiang Jeng‐Tung , Chang Fong‐Ching , Lee Kun‐Wei 
Published: February 2021

AbstractThis study assessed aggression statuses and transitions among children and examined the effects that gender and exposure to online violence can exert on aggression. A sample of 2155 children recruited from 30 primary schools in Taipei, Taiwan completed surveys in both 2015 (5th grade) and 2016 (6th grade). Latent transition analysis (LTA) was performed, and the results identified three latent statuses of aggression: “None,” “School aggression,” and “Cyber‐aggression.” About 10% of children behaved aggressively. When in their 5th‐grade year, boys were more likely than girls to be a school aggressor (6.48% vs. 4.04%) or a cyber‐aggressor (2.37% vs. 1.64%). Among boys who originally were considered to be a school aggressor, 36.19% remained so, 58% renounced their school aggression status, and 5.81% became a cyber‐aggressor. Among girls who originally were considered to be a cyber‐aggressor, 22.23% remained so, 68.29% renounced their cyber‐aggression status, and 9.48% became a school aggressor. Controlling for student's academic performance, household income, and parents' marital status, exposure to online violence was a statistically significant predictor of aggression status for both boys and girls. Children's exposure to online violence appeared to increase the risk of aggression.
Suppressive Myeloid Cells Shape the Tumor Immune Microenvironment
Authors: Xiong Jia , Wang Hui , Wang Qingqing 
Published: February 2021

AbstractCancer is the outcome of the conflict between the host immune system and cancer cells. The crosstalk between immune cells and tumor cells within the tumor microenvironment (TME) influences tumor progression and metastasis. Many studies have clarified the cellular and molecular events that can induce cancer cells to escape immune surveillance, including those involving tumor‐induced myeloid cell‐mediated immunosuppression. Emerging evidence indicates that tumor‐infiltrating myeloid cells (TIMs) accelerate tumor growth and induce angiogenesis, metastasis, and therapy resistance once converted into potent immunosuppressive cells. Here, how tumor infiltrating myeloid cells participate in tumor immune evasion and the prospects of these cells in cancer immunotherapy are discussed.

Published: February 2021

AbstractRapid damping of interfaces experiencing vibrations is critical to the performance of many complex mechanical systems ranging from airplanes to human bodies. Current synthetic materials utilized in vibration damping are limited by either their damping frequency range, tunability, or environmental stability. Here, it is shown how single metal ion cross‐linked hydrogels exhibit tunable damping across a large frequency range and multiple metal ion hydrogels exhibit broadband damping within a single material. Additionally, an enhanced resistance to freezing and dehydration is shown with the use of glycerol as a cosolvent. It is expected that material design principles presented here will help advance the development of programmable damping materials better able to meet the demands of sustained operation under broad environmental conditions.

AbstractMetallic two‐dimensional conductive nanomaterials are extensively explored in stretchable strain sensors, which have promising applications ranging from health monitoring to human–machine manipulation. However, there are limited materials available in this category, and their sensing abilities need to be strengthened. Herein, a controllable deoxidation–nitridation strategy via the pyrolysis of an amine nitrogen source to synthesize oxygen‐doped vanadium nitride (VNO) nanosheets with high conductivity is reported. Its metallic characteristics and low dimensionality, together with layer‐to‐layer slippage make VNO particularly suitable for stretchable strain sensors with remarkable performance, including extraordinary sensitivity (a maximum gauge factor of 2667), wide detection range (0–100%), high durability (over 6000 cycles), and rapid response (44 ms). Furthermore, the strain sensors can capture various physiological signals; in particular, a state‐of‐the‐art wireless vehicle control system designed for differently abled people is fabricated based on the sensors. Moreover, by engineering the thickness of the VNO layer, it can behave as an elastic conductor, demonstrating its feasibility for stretchable wiring.

Authors: Primo Gastón A. , Mata Alvaro 
Published: February 2021

AbstractBiological structures are inherently complex in nature. Structural hierarchy, chemical anisotropy, and compositional heterogeneity are ubiquitous in biological systems and play a key role in the functionality of living systems. For decades, methods such as soft lithography have enabled recreation of such arrangements through precise spatial control of molecular patterns in 2D. With technological advances and increasing understanding of molecular and structural biology, there has been an increasing interest in recreating such spatial organizations in 3D. In this review, a comprehensive summary of the latest technologies being used to create 3D patterns of functional molecules within hydrogels for tissue engineering applications is presented. The review is divided into five groups of technologies defined according to the main driving force used to fabricate the patterns including light, precise chemical design, microfluidics, 3D printing, and non‐contact forces (i.e. electric, magnetic, or acoustic fields and self‐assembly).

Published: February 2021

AbstractFor the low‐cost fabrication of large‐area, durable perovskite solar cells, it is of pivotal importance to engineer organic semiconducting films with a combined property of matched energy level, sufficiently large conductivity, high glass transition temperature, and excellent solution processability. Toward this goal, herein an in silico tailored molecular semiconductor (T5HE‐OMeTPA) with triple axial chirality, by joint use of thia[5]helicene and ethylenedioxythiophene, is reported. T5HE‐OMeTPA with a reduced reorganization energy of hole transfer can be exploited as the hole transport layer for perovskite solar cells with 21% efficiency, which also display excellent long‐term stability at 60 °C. The doped, sufficiently conductive T5HE‐OMeTPA composite with a glass transition temperature of 121 °C not only exhibits persistent film morphology under thermal stress, but also surprisingly damps the motion of diffusive components of perovskite for a better control of the degradation of photoactive layer. The translational motion of both ions and molecules is intrinsically associated with the glass transition of a doped molecular semiconductor composite, which is in stark contrast to the microscopic fashion for the glass transition of an undoped molecular semiconductor, that is, thermally activated rotation of diphenylamine.

Published: February 2021

AbstractLithium (Li) metal anodes exhibit intriguing advantages for application in high‐energy‐density batteries. However, the short cycle life and security issues of these anodes induced by the dendrite growth and huge volumetric change of Li severely limit their practical application. Herein, a heuristic method to fabricate a self–supported seaweed‐like Li metal anode directly to improve the cycle life of Li metal batteries, is reported. The unique seaweed‐like morphology of the Li anode facilitates the dispersion of the local current density, impeding the uneven growth of Li dendrites, and remits the volume expansion of the anode, leading to excellent cycle performance. The as‐prepared Li metal anode exhibits excellent plating–stripping stability over 600 cycles at high current density of 2 mA cm−2 and delivers excellent stability even with the Li4Ti5O12 cathode in the full cell. This study provides a facile strategy to prepare stable and dendrite‐free Li anodes by controlling the morphology of Li metal. Thus, this study can further inspire new research ideas for preparing stable Li metal anodes.

Published: February 2021

AbstractTendon and ligament injuries caused by trauma and degenerative diseases are frequent and affect diverse groups of the population. Such injuries reduce musculoskeletal performance, limit joint mobility, and lower people's comfort. Currently, various treatment strategies and surgical procedures are used to heal, repair, and restore the native tissue function. However, these strategies are inadequate and, in some cases, fail to re‐establish the lost functionality. Tissue engineering and regenerative medicine approaches aim to overcome these disadvantages by stimulating the regeneration and formation of neotissues. Design and fabrication of artificial scaffolds with tailored mechanical properties are crucial for restoring the mechanical function of tendons. In this review, the tendon and ligament structure, their physiology, and performance are presented. On the other hand, the requirements are focused for the development of an effective reconstruction device. The most common fiber‐based scaffolding systems are also described for tendon and ligament tissue regeneration like strand fibers, woven, knitted, braided, and braid‐twisted fibrous structures, as well as electrospun and wet‐spun constructs, discussing critically the advantages and limitations of their utilization. Finally, the potential of multilayered systems as the most effective candidates for tendon and ligaments tissue engineering is pointed out.
Review on Recent Developments in 2D Ferroelectrics: Theories and Applications
Authors: Qi Lu , Ruan Shuangchen , Zeng Yu‐Jia 
Published: February 2021

AbstractAlthough only a few 2D materials have been predicted to possess ferroelectricity, 2D ferroelectrics are expected to play a dominant role in the upcoming nano era as important functional materials. The ferroelectric properties of 2D ferroelectrics are significantly different than those of traditional bulk ferroelectrics owing to their intrinsic size and surface effects. To date, 2D ferroelectrics have been reported to exhibit diverse properties ranging from bulk photovoltaic and piezoelectric/pyroelectric effects to the spontaneous valley and spin polarization. These properties are either dependent on ferroelectric polarization or coupled with it for easy electric control, thus making 2D ferroelectrics applicable to multifunctional nanodevices. At present, cumulative efforts are being made to explore 2D ferroelectrics in theories, experiments, and applications. Herein, such theories and methods are briefly introduced. Subsequently, intrinsic and extrinsic origins of 2D ferroelectricity are separately summarized. In addition, invented or laboratory‐validated 2D ferroelectric‐based applications are listed. Finally, the existing challenges and prospects of 2D ferroelectrics are discussed.

AbstractPolymer composite films containing fillers comprising quasi‐1D van der Waals materials, specifically transition metal trichalcogenides with 1D structural motifs that enable their exfoliation into bundles of atomic threads, are reported. These nanostructures are characterized by extremely large aspect ratios of up to ≈106. The polymer composites with low loadings of quasi‐1D TaSe3 fillers (<3 vol%) reveal excellent electromagnetic interference shielding in the X‐band GHz and extremely high frequency sub‐THz frequency ranges, while remaining DC electrically insulating. The unique electromagnetic shielding characteristics of these films are attributed to effective coupling of the electromagnetic waves to the high‐aspect‐ratio electrically conductive TaSe3 atomic‐thread bundles even when the filler concentration is below the electrical percolation threshold. These novel films are promising for high‐frequency communication technologies, which require electromagnetic shielding films that are flexible, lightweight, corrosion resistant, inexpensive, and electrically insulating.

Published: February 2021

AbstractAll‐solid‐state batteries based on a Li metal anode represent a promising next‐generation energy storage system, but are currently limited by low current density and short cycle life. Further research to improve the Li metal anode is impeded by the lack of understanding in its failure mechanisms at lithium–solid interfaces, in particular, the fundamental atomistic processes responsible for interface failure. Here, using large‐scale molecular dynamics simulations, the first atomistic modeling study of lithium stripping and plating on a solid electrolyte is performed by explicitly considering key fundamental atomistic processes and interface atomistic structures. In the simulations, the interface failure initiated with the formation of nano‐sized pores, and how interface structures, lithium diffusion, adhesion energy, and applied pressure affect interface failure during Li cycling are observed. By systematically varying the parameters of solid‐state lithium cells in the simulations, the parameter space of applied pressures and interfacial adhesion energies that inhibit interface failure during cycling are mapped to guide selection of solid‐state cells. This study establishes the atomistic modeling for Li stripping and plating, and predicts optimal solid interfaces and new strategies for the future research and development of solid‐state Li‐metal batteries.

AbstractHuman fingers exhibit both high sensitivity and wide tactile range. The finger skin structures are designed to display gradient microstructures and compressibility. Inspired by the gradient mechanical Young's modulus distribution, an electric‐field‐induced cationic crosslinker migration strategy is demonstrated to prepare gradient ionogels. Due to the gradient of the crosslinkers, the ionogels exhibit more than four orders of magnitude difference between the anode and the cathode side, enabling gradient ionogel‐based flexible iontronic sensors having high‐sensitivity and broader‐range detection (from 3 × 102 to 2.5 × 106 Pa) simultaneously. Moreover, owing to the remarkable properties of the gradient ionogels, the flexible iontronic sensors also show good long‐time stability (even after 10 000 cycles loadings) and excellent performance over a wide temperature range (from −108 to 300 °C). The flexible iontronic sensors are further integrated on soft grips, exhibiting remarkable performance under various conditions. These attractive features demonstrate that gradient ionogels will be promising candidates for smart sensor applications in complex and extreme conditions.

AbstractControlling selective ion transport is core for developing novel membrane technologies for high‐efficiency ion separation and energy conversion, and biosensing applications. Metal–organic frameworks (MOFs), an emerging family of porous crystalline materials with permanent porosity, Ångstrom‐sized pores and various functional sites, have been recently found to share some similar pore structures and functionalities analogous to biological ion channels. Extensive efforts have been made to develop new strategies for the construction of MOF‐based ion‐selective membranes for efficient ion separation and energy harvesting. Herein, in this progress report, the rational strategies for fabrication of MOF‐based membranes are introduced first, followed by the analysis of their capabilities for selective ion transport. Then, the applications of MOF‐based ion‐selective membranes for ion separation and energy conversion are discussed in detail. Finally, a summary and some recommendations for future directions in the field are presented.

Published: February 2021

AbstractReal‐time and accurate detection of localized temperature on curved human bodies is always highly demanded for health and medical applications. In this work, a bioinspired temperature‐sensitive yarn is designed and fabricated with different coverage degrees, in which pure metal fiber of platinum instead of conductive polymers is incorporated. The temperature sensitive yarn is observed with excellent temperature–resistance linearity (>0.99), high sensitivity (≈3.00 × 10−3 °C−1), high repeatability (>1000 cycles), fast response, and low hysteresis (<3%). Most importantly and thanks to the bioinspired structure, this superelastic yarn supports extremely large strain of up to 300%, yet can still maintain original electrical integrity. It is further observed that the temperature coefficient of resistance and thermal response velocity are improved by the coverage degrees, which are attributed to the bioinspired helical structure. A bracelet based on the bioinspired yarn is then fabricated to detect temporal skin temperature around the wrist. Not only mechanical advantages, but also chemical stability in human sweat is observed for the bracelet. It is suggested that the bioinspired temperature‐sensitive yarn can be implemented for continuous monitoring of skin temperature for healthcare or medical applications.

AbstractThe development of a class of simple‐structure‐based small molecule iridium complexes with adjustable color emission from blue to near‐infrared (NIR) remains a major challenge. A novel straightforward strategy toward a series of three types of charged ligand (0, −1, −2)‐based neutral iridium(III) complexes is described, as it can be easily obtained by efficient three‐step synthesis. All the complexes contain an unusual dianionic ligand (−2) biphenyl and show a great color variation from blue–green (465–503 nm) to NIR (688–706 nm) by controlling different neutral (0) and monoanionic (−1) ligands. Notably, all the NIR‐emitting iridium(III) complexes have excellent chemical and thermal stability, which makes them easy to sublimate and purify, and are eventually applied to organic light‐emitting diode device with a good external quantum efficiency of 2.5%, and low efficiency roll‐off and turn‐on voltage (3 V). This study opens an important avenue for the construction of novel phosphorescent iridium(III) complex materials with tunable properties featuring three types of charged ligands (0, −1, −2), thus providing new opportunities for their optoelectronic applications.

AbstractGiven its abundance and clean combustion, natural gas (NG) is one of the leading sources of energy to meet present demands. However, the storage and transportation of NG remain challenging. Besides the commonly used NG storage methods such as compression and liquefaction, adsorbed NG is an attractive alternative. Here, the requirements for vehicles to be powered by adsorbed natural gas (ANG) are examined. Despite top‐performing adsorbents and present‐day engineering solutions, there remain obstacles that prevent vehicles fueled by ANG from becoming commonplace. Herein, these challenges are highlighted to inspire engineering solutions for onboard ANG systems.
