AbstractElectro‐ionic soft actuators, capable of continuous deformations replacing non‐compliant rigid mechanical components, attract increasing interest in the field of next‐generation metaverse interfaces and soft robotics. Here, a novel MXene (Ti3C2Tx) electrode anchoring manganese‐based 1,3,5‐benzenetricarboxylate metal‐organic framework (MnBTC) for ultrastable electro‐ionic artificial muscles is reported. By a facile supramolecular self‐assembly, the Ti3C2Tx‐MnBTC hybrid nanoarchitecture forms coordinate bond, hydrogen bond, and hydrophilic interaction with the conducting polymer of poly(3,4‐ethylenedioxythiophene) polystyrene sulfonate (PEDOT:PSS), resulting in a mechanically flexible and electro‐ionically active electrode. The superior electrical and electrochemical performances of the electrode stem from the synergistic effects between intrinsically hierarchical nanoarchitecture of MnBTC and rapid electron transport behavior of Mxene, leading to fast diffusion and accommodation of ions in the ion‐exchangeable membrane. The developed artificial muscle based on Ti3C2Tx‐MnBTC is found to exhibit high bending displacement (12.5 mm) and ultrafast response time (0.77 s) under a low driving voltage (0.5 V), along with wide frequency response (0.1–10 Hz) and exceptional stability (98% retention at 43,200 s) without any distortion of actuation performance. Furthermore, the designed electro‐active artificial muscle is successfully used to demonstrate mimicry of eye motions including eyelid blinking and eyeball movement in a doll.

AbstractSimultaneously attaining high gravimetric energy density (Eg) and volumetric energy density (Ev) in lithium‐sulfur (Li–S) batteries is a longstanding challenge that has to be solved for practical application, which demands breakthroughs in electrode materials with optimized functionality and structure. Herein, anthraquinone‐containing, reactive‐type polymer tubes (PQT) that can be used to regulate the redox chemistry of sulfur species are designed and prepared for practical Li–S batteries. PQT favors a similar redox potential window as sulfur, which effectively facilitates the immobilization and conversion of sulfur species through a reversible lithiation/delithiation process. Its tubular structure and high tap density is vital to the fabrication of intact electrode with high sulfur loading and minimizing electrolyte intake during battery operation. With all these contributions, Li–S battery with PQT/S cathode exhibits a stable cycling capacity (73% at 2.0 C over 1000 cycles), remarkable rate performance (514.2 mAh g−1 at 10 C), and a high areal capacity of 7.20 mAh g−1 with high sulfur loading under lean electrolyte condition. More importantly, the assembled Li–S pouch cell delivers an Eg of 329 Wh kg−1 and an Ev of 401 Wh L−1, which meets the requirement for practical operation.

AbstractThe integration of organic photovoltaic (OPV) modules on greenhouses is an encouraging practice to offset the energy demands of crop growth and provide extra functionality to dedicated farmland. Nevertheless, such OPV devices must meet certain optical and stability requirements to turn net zero energy greenhouse systems a reality. Here a donor:acceptor polymer blend is optimized for its use in laminated devices while matching the optical needs of crops. Optical modeling is performed and a greenhouse figure‐of‐merit is introduced to benchmark the trade‐off between photovoltaic performance and transparency for both chloroplasts and humans. Balanced donor:acceptor ratios result in better‐performing and more thermally stable devices than acceptor‐enriched counterparts. The optimized polymer blend and state‐of‐the‐art polymer:small‐molecule blends are next transferred to 25 cm2 laminated modules processed entirely from solution and in ambient conditions. The modules are mounted on a greenhouse as standalone or 4‐terminal tandem configurations and their outdoor stability is tracked for months. The study reveals degradation modes undetectable under laboratory conditions such as module delamination, which accounts for 10–20% loss in active area. Among the active layers tested, polymer:fullerene blends are the most stable and position as robust light harvesters in future building‐integrated OPV systems.

AbstractZero‐thermal‐expansion (ZTE) alloys, as dimensionally stable materials, are urgently required in many fields, particularly in highly advanced modern industries. In this study, high‐performance ZTE with a negligible coefficient of thermal expansion av as small as 2.4 ppm K−1 in a broad temperature range of 85–245 K is discovered in Hf0.85Ta0.15Fe2C0.01 magnet. It is demonstrated that the addition of trace interstitial atom C into Ta‐substituted Hf0.85Ta0.15Fe2 exhibits significant capability to tune the normal positive thermal expansion into high‐performance ZTE via enhanced magnetoelastic coupling in stabilized ferromagnetic structure. Moreover, direct observation of the magnetic transition between ferromagnetic and triangular antiferromagnetic states via Lorentz transmission electron microscopy, along with corresponding theoretical calculations, further uncovers the manipulation mechanism of ZTE and negative thermal expansion. A convenient and effective method to optimize thermal expansion and achieve ZTE with interstitial C addition may result in broadened applications based on the strong correlation between the magnetic properties and crystal structure.

AbstractAl/PMMA/CS/PMMA/ITO structure devices are fabricated using polymethyl methacrylate (PMMA) and chitosan (CS) as dielectric layer materials. Its electrical characteristics and conductive mechanism are studied using its own physical characteristics to build a memristor true random number generator (TRNG). The generated true random sequence is optimized by a field programmable gate array (FPGA), and the optimized random number sequence is tested by the National Institute of Standards and Technology (NIST) to analyze its randomness. The pipeline structure is introduced to optimize the whole image encryption system, and the optimized random number sequence is used to realize image encryption inside the FPGA. Then, the encrypted image is displayed on a liquid crystal display (LCD) screen to realize random number generation and image encryption of all hardware. Finally, the encrypted image is analyzed.

AbstractWith increasing CO2 emission and energy scarcity, electrocatalytic CO2 reduction reaction (CO2RR) offers an attractive solution for CO2 resource utilization using sustainable electrical energy. Ag‐based catalysts with high‐curvature nanoneedle structure exhibit the potential to achieve high CO2RR activity, but suffer from insufficient stability due to the vulnerability of the high‐curvature structure during CO2RR. Herein, the uniform porous Zn conformal coating on high‐curvature dendritic Ag nanoneedles (AgNNs@Zn) by vacuum thermal evaporation is prepared. As the surface sacrificial shell, the dissolution and reconstruction of Zn protect the inner Ag core, thus enhancing the CO2RR stability of AgNNs@Zn. The concentration of Ag+ in the electrolyte after 2 h CO2RR electrolysis markedly reduces from 2.4 ug L−1 in AgNNs to 1.4 ug L−1 in AgNNs@Zn. Moreover, the DFT calculation reveals that the constructed Ag–Zn interfaces can stabilize the *COOH intermediates, which promote the selectivity of CO2 reduction into CO. As a result, the optimized AgNNs@Zn catalyst exhibits the FECO of ≈91% at −0.86 V versus RHE in H‐cell, and FECO of 90% at 100 mA cm−2 above 12 h in flow cell. This work provides a feasible strategy to synthesize bimetallic catalysts with core–shell structure for better CO2RR performance.

Published: December 2022

AbstractIn doped organic light‐emitting diodes (OLEDs), the host materials play an important role in emitting layers. Most studies about host materials mainly focus on their energy levels and carrier transport behaviors, while less attention is paid to their influence on the dipole orientation of dopants, which closely associate with the light out‐coupling efficiency (ηout) of the device. Herein, a linear polar host material (l‐CzTRZ) consisting of carbazole donor, triazine acceptor, and the conjugated para‐terphenyl skeleton is developed and its crystal and electronic structures, thermal and electrochemical stabilities, optical property, and carrier transport ability are investigated. l‐CzTRZ prefers ordered horizontal orientation and favors electron transport in neat film. More importantly, it can promote horizontal dipole orientation for the dopants via dipole‐dipole interaction, furnishing an excellent horizontal dipole ratio of 91.5% and thus a high ηout of 43% for the phosphorescent dopant (PO‐01‐TB). Consequently, the OLED with l‐CzTRZ host and PO‐01‐TB dopant attains state‐of‐the‐art electroluminescence efficiencies of 135.5 cd A−1, 135.7 lm W−1 and 41.3%, with a small roll‐off of 9.7% at 5000 cd m−2 luminance. The presented significant impact of the host on the dipole orientation of the dopant shall enlighten the design of host materials to improve OLED performance.

Published: December 2022

AbstractImmersion‐based vital dyes were tested as a marking method for use in larval smelt mark–recapture studies. We assessed five fluorescent dyes as a mark for juvenile osmerids: 4‐Di‐1‐ASP, BODIPY FL C12, BODIPY 505/515, Nile red, and calcein. We marked juvenile Delta Smelt, Hypomesus transpacificus, as a proxy for Longfin Smelt, Spirinchus thaleichthys, to determine the efficacy of each as a batch marking technique for osmerids based on dye performance and survival. All groups of Delta Smelt including control groups exhibited high mortality (71%–100%, 5 days after trial), and lowest survival was observed in 4‐Di‐1‐ASP‐treated fish. Highest survival was observed in Nile red‐ and BODIPY FL C12‐treated fish. Fluorescence observations indicated that the brightest, visible fluorescence was seen in calcein and to a lesser extent, 4‐Di‐1‐ASP, followed by BODIPY FL C12 and Nile red. In addition to dye performance, it is recommended that immersion techniques that improve survival be considered.

ObjectivePolygenic variation accounts for a substantial portion of the risk of Alzheimer's disease (AD), but its effect on the rate of fibrillar‐tau accumulation as a key driver of dementia symptoms is unclear.MethodsWe combined the to‐date largest number of genetic risk variants of AD (n = 85 lead single‐nucleotide polymorphisms [SNPs]) from recent genome‐wide association studies (GWAS) to generate a polygenic score (PGS). We assessed longitudinal tau‐positron emission tomography (PET), amyloid‐PET, and cognition in 231 participants from the Alzheimer's Disease Neuroimaging Initiative (ADNI). Using the PGS, together with global amyloid‐PET, we predicted the rate of tau‐PET increases in Braak‐stage regions‐of‐interest and cognitive decline. We also assessed PGS‐risk enrichment effects on the required sample size in clinical trials targeting tau pathology.ResultsWe found that a higher PGS was associated with higher rates of tau‐PET accumulation, in particular at elevated amyloid‐PET levels. The tau‐PET increases mediated the association between PGS and faster cognitive decline. Risk enrichment through high PGS afforded sample size savings by 34%.InterpretationOur results demonstrate that the PGS predicts faster tau progression and thus cognitive decline, showing utility to enhance statistical power in clinical trials.

Published: December 2022

AbstractMany biopharmaceutical industries have focused on the screening for novel cell lines and producers for manufacturing of advanced therapeutics. Commercial scale productions at reduced cost and improved productivity are only possible with the bioreactor systems. Animal cell culture bioreactors have all started to draw attention in view that 20th century and advanced significantly over the previous few a long time especially with the need for viral vaccine productions, monoclonal antibody productions and in vitro meat productions. To produce these high value‐added products in large scales, bioreactor configurations are advanced to reduce investment and operational costs, control the process parameters, enhance productivity, and make easier scale‐up. Although novel bioreactor systems have interested in recent years, conventional bubble column and airlift systems are still the most familiar and experienced bioreactors. Pneumatically agitated bioreactors have been studied for many years in animal cell culture. This current review intends to provide an overview of pneumatic bioreactor productions for animal cell culture applications in key items of cell culture and bioreactor technology, for example, design parameters, transport phenomena during cultivation, shear sensitivity of cells. Besides, the previous studies, investigated that the design parameters and process conditions for productivity and shear sensitivity, have been reviewed and summarized.

AbstractIn this study, we have demonstrated, for the first time, the muscular protective effects of Piranhea trifoliata bark extract against Paraquat (PQ)‐induced oxidative stress in Drosophila melanogaster. Exposure of D. melanogaster (Canton Special) to PQ caused oxidative stress, as evidenced by protein carbonyl and elevated acetylcholinesterase (AChE) activity levels. However, a diet supplemented with the P. trifoliata extracts (0.1 mg/ml) for 10 days ameliorates protein carbonyl levels and enzymatic activities of AChE and citrate synthase to prevent PQ damage. Also, P. trifoliata bark extracts showed in phytochemical assays the presence of phenols, at 46.06 mg EAG/g extract of total phenolic compounds, and a 40% 2,2‐diphenyl‐1‐picryl‐hydrazyl scavenging effect. The study showed the muscular protective function of the P. trifoliata extracts in D. melanogaster exposed to PQ. On the basis of the results, we contemplate that the bark of P. trifoliata might prevent and ameliorate human diseases caused by oxidative stress. The muscular action of the P. trifoliata extract can be attributed to the antioxidant constituents, while the precise mechanism of its action needs further investigation.

AbstractIn biomedical implant technology, nanosurface such as titania nanotube arrays (TNA) could provide better cellular adaptation, especially for long‐term tissue acceptance response. Mechanotransduction activities of TNA nanosurface could involve the cytoskeleton remodeling mechanism. However, there is no clear insight into TNA mechano‐cytoskeleton remodeling activities, especially computational approaches. Epithelial cells have played critical interface between biomedical implant surface and tissue acceptance, particularly for long‐term interaction. Therefore, this study investigates genomic responses that are responsible for cell–TNA mechano‐stimulus using epithelial cells model. Findings suggested that cell–TNA interaction may improve structural and extracellular matrix (ECM) support on the cells as an adaptive response toward the nanosurface topography. More specifically, the surface topography of the TNA might improve the cell polarity and adhesion properties via the interaction of the plasma membrane and intracellular matrix responses. TNA nanosurface might engross the cytoskeleton remodeling activities for multidirectional cell movement and cellular protrusions on TNA nanosurface. These observations are supported by the molecular docking profiles that determine proteins' in silico binding mechanism on TNA. This active cell‐surface revamping would allow cells to adapt to develop a protective barrier toward TNA nanosurface, thus enhancing biocompatibility properties distinctly for long‐term interaction. The findings from this study will be beneficial toward nano‐molecular knowledge of designing functional nanosurface technology for advanced medical implant applications.

Published: December 2022

AbstractOrganic electrode materials have been extensively researched for alkali metal batteries such as Li, Na, and K batteries due to their unique redox mechanism independent of types of charge‐carrying ions and flexible intermolecular structures facilitating the insertion of bulky metal‐ions. This study presents an ortho‐isomer of triptycene tribenzoquinone (o‐TT) as a universal organic cathode material for alkali metal batteries. To elevate the redox potentials of previously reported triptycene tribenzoquinone (TT) without sacrificing its large specific capacity (∼386 mAh g−1), the structural isomers of benzoquinone units in the TT molecule were designed by changing their carbonyl group position from para‐ to ortho‐position. Due to multi‐electron redox reactions and the elevated redox potentials, o‐TT shows high energy densities of 945, 767, and 597 Wh kg−1 in Li, Na, and K cells, respectively. Finally, its cycle stability is significantly improved by fabricating composite electrodes with disordered mesoporous carbon (DOMC).

AbstractBefore the COVID‐19 pandemic, the world struggled to address growing educational inequalities and fulfil the commitment to Sustainable Development Goal 4, which seeks to ensure inclusive and equitable quality education and promote lifelong learning opportunities for all. The pandemic has exacerbated these inequalities and changed how education functions, moving to online and hybrid methods. The challenges in global education highlighted and worsened by the pandemic make it necessary to re‐evaluate education systems and the policies in place to support access, quality and equal opportunity. This article focuses on analysing education policies at a national level. It tests a pilot policy analysis tool, the International Education Index (IEI), developed as a starting point to begin this reconsideration and create an accessible and comprehensive way to evaluate national education systems to inform decision‐making and policies in the new context. This research uses Ireland and Northern Ireland to test the IEI pilot tool. The IEI consists of 54 questions across nine indicators, including institutional frameworks, education strategies, digital skills and infrastructure, twenty‐first century skills, access to basic social services, adherence to international standards, legal frameworks, data gathering and availability and international partnerships. Countries can score 108 points to be categorised as having developed, emerging or nascent national education systems. Ireland scored 94 and Northern Ireland 81, indicating that they have developed national education systems.
Control of phosphatidylinositol‐3‐kinase signaling by nanoscale membrane compartmentalization
Authors: Cabral‐Dias Rebecca , Antonescu Costin N. 
Published: December 2022

AbstractPhosphatidylinositol‐3‐kinases (PI3Ks) are lipid kinases that produce 3‐phosphorylated derivatives of phosphatidylinositol upon activation by various cues. These 3‐phosphorylated lipids bind to various protein effectors to control many cellular functions. Lipid phosphatases such as phosphatase and tensin homolog (PTEN) terminate PI3K‐derived signals and are critical to ensure appropriate signaling outcomes. Many lines of evidence indicate that PI3Ks and PTEN, as well as some specific lipid effectors are highly compartmentalized, either in plasma membrane nanodomains or in endosomal compartments. We examine the evidence for specific recruitment of PI3Ks, PTEN, and other related enzymes to membrane nanodomains and endocytic compartments. We then examine the hypothesis that scaffolding of the sources (PI3Ks), terminators (PTEN), and effectors of these lipid signals with a common plasma membrane nanodomain may achieve highly localized lipid signaling and ensure selective activation of specific effectors. This highlights the importance of spatial regulation of PI3K signaling in various physiological and disease contexts.
