AbstractWater‐repellent superhydrophobic surfaces are ubiquitous in nature. The fundamental understanding of bio/bio‐inspired structures facilitates practical applications surmounting metastable superhydrophobicity. Typically, the hierarchical structure and/or reentrant morphology have been employed hitherto to suppress the Cassie‐Baxter to Wenzel transition (CWT). Herein, a new design concept is reported, an effect of concave structure, which is vital for the stable superhydrophobic surface. The thermodynamic and kinetic stabilities of the concave pillars are evaluated by continuous exposure to various hydrostatic pressures and sudden impacts of water droplets with various Weber numbers (We), comparing them to the standard superhydrophobic normal pillars. Specifically, the concave pillar exhibits reinforced impact resistance preventing CWT below a critical We of ≈27.6, which is ≈1.6 times higher than that of the normal pillar (≈17.0). Subsequently, the stability of underwater air film (plastron) is investigated at various hydrostatic pressures. The results show that convex air caps formed at the concave cavities generate downward Laplace pressure opposing the exerted hydrostatic pressure between the pillars, thus impeding the hydrostatic pressure‐dependent underwater air diffusion. Hence, the effects of trapped air caps contributing to the stable Cassie‐Baxter state can offer a pioneering strategy for the exploration and utilization of superhydrophobic surfaces.

AbstractOptical neural networks (ONNs) have shown great promise in overcoming the speed and efficiency bottlenecks of artificial neural networks. However, the absence of high‐speed, energy‐efficient nonlinear activators significantly impedes the advancement of ONNs and their extension to ultrafast application scenarios like real‐time intelligent signal processing. In this work, a novel silicon/graphene ultrafast all‐optical nonlinear activator, leveraging the hybrid integration of silicon slot waveguides, plasmonic slot waveguides, and monolayer graphene is demonstrated. Exploiting the exceptional picosecond‐scale photogenerated carrier relaxation time of graphene, the response time of the activator is markedly reduced to ≈93.6 ps, establishing all‐optical activator as the fastest known in silicon photonics to knowledge. Moreover, the all‐optical nonlinear activator holds a low threshold power of 5.49 mW and a corresponding power consumption per activation of 0.51 pJ. Its feasibility and capability for use in ONNs, manifesting performance comparable with commonly used activation functions are experimentally confirmed. This breakthrough in speed and energy efficiency of all‐optical nonlinear activators opens the door to significant improvements in the performance and applicability of ONNs.

AbstractDevelopment of chiral aggregation‐induced emission (AIE) materials toward hierarchical self‐assembly is crucial to reveal the origin and evolution of life. In this work, a pair of chiral AIE enantiomers is fabricated by attaching the typical AIE units to the chiral binaphthyl core via a single bond linkage. The AIE behavior is inherited from the introduced AIE unit while the binaphthyl unit can not only improve the photo‐physical properties but also provide the whole molecules with chirality. Moreover, as driven by the dipolar structure and chirality of the AIEgens, the hierarchical self‐assembly with different morphologies such as spheres, ribbons or fibers, flowers, and even bigger structures with various sizes can be dynamically monitored with the assembled time, which provided a favorable evidence to study the structural evolution from molecular level to a higher‐level structure. On the other hand, these AIEgens can act strong electronic acceptors due to the introduced AIE unit. By complexing them with strong electronic donors, the resulting intermolecular charge transfer can induce remarkable red emissions with the tunable properties which is much different from their individuals. This enabled it as a facile, economic, and flexible approach to develop organic photoelectric materials.

AbstractThe development of low‐cost, readily scalable catalytic systems for green hydrogen production is crucial for diverse research and industrial applications. This work demonstrates the facile coupling of carbon/NiFe‐layered double hydroxide (LDH) onto flexible polyethylene terephthalate (PET) substrates deposited by blade coating and spray coating techniques. These low‐temperature solution processes enable high‐throughput electrode fabrication. The resulting carbon electrode exhibits sheet resistance of 25 Ω sq−1, comparable to other state‐of‐the‐art works, and displays excellent adhesion to the substrate and catalyst layer, thereby ensuring system stability. Remarkably, the developed electrode exhibits high catalytic activity for the oxygen evolution reaction (OER), achieving an overpotential of 215.9 and 267.4 mV at 10 mA cm−2 in rigid and flexible substrates respectively, and maintaining its performance even at 10 mA cm−2 for 24 h. This work highlights the potential of this methodology for producing readily transportable, flexible electrocatalytic systems with exceptional performance and minimal surface treatment of the substrate. Additionally, the use of low‐cost, readily recyclable PET plastic aligns with the principles of circular economy, promoting the integration of this platform into both research and industrial environments.
Noise‐Aware Active Learning to Develop High‐Temperature Shape Memory Alloys with Large Latent Heat

Published: October 2024

AbstractShape memory alloys (SMAs) with large latent heat absorbed/released during phase transformation at elevated temperatures benefit their potential application on thermal energy storage (TES) in high temperature environment like power plants, etc. The desired alloys can be designed quickly by searching the vast component space of doped NiTi‐based SMAs via data‐driven method, while be challenging with the noisy experimental data. A noise‐aware active learning strategy is proposed to accelerate the design of SMAs with large latent heat at elevated phase transformation temperatures based on noisy data. The optimal noise level is estimated by minimizing the model error with incorporation of a range of noise levels as noise hyper‐parameters into the noise‐aware Kriging model. The employment of this strategy leads to the discovery of the alloy with latent heat of –36.08 J g−1, 9.2% larger than the best value (–33.04 J g−1) in the original training dataset within another four experiments. Additionally, the alloy represents high austenite finish temperature (481.71°C) and relatively small hysteresis. This promotes the latent heat TES application of SMAs in high temperature circumstance. It is expected that the noise‐aware approach can be convenient for the accelerated materials design via the data‐driven method with noisy data.

Published: October 2024

AbstractDonor‒acceptor covalent organic frameworks (D‒A COFs) have been regarded as promising materials for photocatalytic water splitting because of their tunable band gaps. However, their efficiency is hindered by fast charge recombination and low photostability. Herein, we proposed a donor structural engineering strategy for improving the photocatalytic activity of D‒A COFs to tackle these problems. Two benzothiadiazole‐based D‒A COFs (DHU‐COF‐BB and DHU‐COF‐BP) with distinct donors were prepared for photocatalytic H2 evolution reaction (HER). As a comparison, DHU‐COF‐TB without benzothiadiazole moieties was also designed and synthesized. Impressively, the photocatalytic H2 production rate of DHU‐COF‐BB reaches 12.80 mmol g−1 h−1 under visible light irradiation (≥420 nm), which was nearly 2.0 and 3.1 times higher than that of DHU‐COF‐BP (6.47 mmol g−1 h−1) and DHU‐COF‐TB (4.06 mmol g−1 h−1), respectively. In addition, the apparent quantum efficiency (AQE) of DHU‐COF‐BB was up to 5.04% at 420 nm. Photocatalytic and electrochemical measurements indicate that the enhanced hydrogen evolution activity of DHU‐COF‐BB can be ascribed to the introduction of appropriate benzene moiety into the donors, which increases the charge separation efficiency and thereby suppresses the electron‒hole recombination. Density functional theory (DFT) calculations revealed that both triphenylamine and benzothiadiazole units are the main active sites for HER over the DHU‐COF‐BB. This work provides new insight into the photocatalytic hydrogen production activity of D‒A COFs by a donor structural engineering strategy.

Published: October 2024

AbstractThe surface coverage of two‐dimensional (2D) materials has been a challenge, requiring facile growth of conformal 2D materials as well as considerations for transparency, energy level, and interface contact. Self‐assembly holds promise for addressing this challenge by constructing precisely structured 2D assemblies using intentionally designed building blocks, guided by diverse noncovalent interactions. In this study, we utilize a self‐assembled 2D supramolecular organic framework (SOF) to cloak inorganic semiconductors and form composite materials for infrared photodetection. The charged SOF backbone regulates the energy levels, facilitating the migration of electrons at the organic‐inorganic interface. Additionally, the oxygen (O) of the ethylene glycol chains forms coordination bonds with the Pb(II) in the inorganic semiconductor, establishing ohmic contacts. The composite device shows excellent detectivity under 500 K blackbody and 1550 nm infrared illumination, achieving D*bb(500 K) of 6.3 × 109 Jones under 500 K blackbody radiation. Moreover, the device exhibits low noise due to the SOF potential barrier impeding the photogenerated and/or thermally excited holes, and high stability as a result of bonding and passivation of vacancy defects. This study showcases the versatile functionality of 2D SOF materials in the field of optoelectronics, opening doors to innovative advancements in composite devices through a self‐assembled organic–inorganic approach.

Published: October 2024

ABSTRACTMitochondrial trifunctional protein (MTP) deficiency is a fatty acid oxidation disorder associated with a spectrum of phenotypes. Patients with high residual enzyme activity tend to have milder phenotypes, and recently, fever‐induced episodic myopathy was reported in association with a thermosensitive form of MTP deficiency. We report a 10‐year‐old male with recurrent episodes of acute flaccid paralysis involving upper and lower extremities in association with bulbar muscle weakness in the context of febrile illness, a phenotype reminiscent of recurrent periodic paralysis. The episodes started at the age of 3 years and have always been followed by full recovery within 1–2 weeks with no residual weakness. Whole exome sequencing revealed a homozygous c.2132C > T, p.(Pro711Leu) variant in HADHA. The variant leads to mildly reduced long‐chain hydroxyacyl‐CoA dehydrogenase (LCHAD) and long‐chain ketoacyl‐CoA thiolase (LCKAT) enzyme activities and reduced MTP protein expression in patient's fibroblasts when cultured at 37°C. Enzyme activities and MTP protein expression diminished when fibroblasts were cultured at 40°C. This is the first published report of confirmed recurrent periodic paralysis as a manifestation of a thermosensitive form of MTP deficiency, and it calls for this condition to be considered when evaluating patients with recurrent periodic paralysis given therapeutic implications.
Sociotechnical governance of misinformation: An Annual Review of Information Science and Technology (ARIST) paper
Authors: Sanfilippo Madelyn Rose , Zhu Xiaohua Awa , Yang Shengan 
Published: October 2024

AbstractMisinformation is a complex and urgent sociotechnical problem that requires meaningful governance, in addition to technical efforts aimed at detection or classification and intervention or literacy efforts aimed at promoting awareness and identification. This review draws on interdisciplinary literature—spanning information science, computer science, management, law, political science, public policy, journalism, communications, psychology, and sociology—to deliver an adaptable, descriptive governance model synthesized from past scholarship on the governance of misinformation. Crossing disciplines and contexts of study and cases, we characterize: the complexity and impact of misinformation as a governance challenge, what has been managed and governed relative to misinformation, the institutional structure of different governance parameters, and empirically identified sources of success and failure in different governance models. Our approach to support this review is based on systematic, structured literature review methods to synthesize and compare insights drawn from conceptual, qualitative, and quantitative empirical works published in or translated into English from 1991 to the present. This review contributes a model for misinformation governance research, an agenda for future research, and recommendations for contextually‐responsive and holistic governance.

Published: October 2024

AbstractA novel peptide‐based chemical fluorescence sensor L (Dansyl‐His‐Pro‐Thr‐Cys‐NH2) was designed and synthesized. This sensor exhibits an “On–Off–On” detection cycle to detect Cu2+, Zn2+, and S2− in solution. According to the chelation‐enhanced fluorescence (CHEF) mechanism, when Zn2+ is present, the fluorescence is significantly enhanced and a blue shift occurs, representing a “Turn‐On” phase of the fluorescence detection mode. Because copper ions (Cu2+) have a paramagnetic quenching sensing mechanism, the fluorescence of L quenches rapidly with the formation of the L‐Cu system, representing the “Turn‐Off” phase. The subsequent introduction of S2− to the L‐Cu system results in the recovery of the L‐fluorescence, thereby representing the second “Turn‐On” phase. As a peptide molecule, the sensor L has several advantages over other types of sensors, including water solubility, high sensitivity, and good biocompatibility, with a very low detection limit. The detection lines of Zn2+ and Cu2+ are 97 nM (R = 0.993) and 75 nM (R = 0.995), respectively. Additionally, the sensor does not exhibit any obvious cell toxicity. These results indicate that this peptide chemiluminescent sensor has the potential to be applied in in vivo detection.
When excessive service turns bad: Service alignment for transaction‐specific needs
Authors: Kim Kawon , Oh Haemoon 
Published: October 2024

AbstractService firms strive to meet and exceed customers' expectations, but more services are not always welcome. To answer the question why extra services may not always lead to positive service evaluations, we examined the effectiveness of service alignment with transaction‐specific needs as a reference standard for service evaluations and challenged the central tenet of expectancy disconfirmation theory. The service alignment model was experimentally evaluated in a normal service (Study 1) and a service failure setting (Study 2). We found that service evaluations depend critically on the degree to which services are aligned to the customer's transaction‐specific needs and that this finding was generalizable across normal and service failure situations. Study 3 addresses the question of whether the three step behavioral process (i.e., comparison antecedents ➔ disconfirmation ➔ evaluations) of expectancy disconfirmation theory is tenable when applied to a different comparison standard (i.e., transaction‐specific needs). We discuss the new boundary conditions of expectancy disconfirmation theory and provide suggestions for future investigations.

AbstractAimsWe conducted a prespecified subanalysis of the POEM trial to assess the association between sex and clinical outcomes following a short 1‐month dual‐antiplatelet‐therapy (DAPT) period after percutaneous coronary intervention (PCI) with bioresorbable polymer everolimus‐eluting stent (BP‐EES) among patients at high bleeding risk (HBR).BackgroundShortening the DAPT period after PCI is an effective bleeding avoidance strategy with contemporary drug‐eluting stents. Whether sex affects the risk of adverse events following PCI is still debated.MethodsPatients at HBR undergoing PCI with BP‐EES were enrolled and treated with 1‐month DAPT. If anticoagulation was needed, study participants received an oral anticoagulant (OAC) in addition to a P2Y12 inhibitor for 1 month, followed by OAC only thereafter. The primary endpoint was a composite of cardiac death, myocardial infarction, or definite/probable stent thrombosis at 12 months. We report sex‐based outcomes of patients included in the POEM study.ResultsWe enrolled 129 (29.1%) women and 314 (70.9%) men. Women were older, with lower hemoglobin levels, and worse renal function. Accordingly, they had a trend for a greater number of HBR criteria fulfilled and a higher PARIS bleeding score. However, they were not at a significantly higher risk for the primary endpoint (men vs. women: 5.17% vs. 3.94%; HR 1.30; 95% CI: 0.48‐3.54, p = 0.61), or any of the hemorrhagic and ischemic secondary endpoints.ConclusionsThis prespecified subanalysis of the POEM trial suggests that 1‐month DAPT following PCI with BP‐EES may be a safe and effective therapeutic strategy for women at HBR.

AbstractBackgroundPatients with non‐alcoholic fatty liver disease (NAFLD) often exhibit hepatic steatosis and dyslipidemia. Studies have shown that intestinal microorganisms are closely related to the occurrence of NAFLD and atherosclerosis. Our previous study has underscored the protective role of microRNA‐30a‐5p (miR‐30a‐5p) against atherosclerosis.Methods and ResultsIn the present study, we aimed to elucidate the effect and underlying mechanism of the intestinal microorganisms of miR‐30a‐5p knockout (KO) mice on NAFLD. Our findings demonstrated that KO exacerbated high‐fat diet (HFD)‐induced hepatic steatosis and disrupted liver function, as evidenced by elevated levels of total cholesterol, low‐density lipoprotein, alanine aminotransferase, aspartate transaminase, and total bile acids in serum. Fecal microbiota from HFD‐fed KO mice induced hepatic steatosis, dyslipidemia, and higher levels of enzymes indicative of liver damage in wild‐type mice. Remarkably, KO mice significantly intensified the above effects. 16s rDNA sequencing and metabolomics of the intestinal microbiota in the HFD‐treated KO and WT mice showed that the loss of miR‐30a‐5p resulted in intestinal microbiota imbalance and was highly related to the arachidonic acid metabolic pathway. Targeted metabolomic in the liver tissues unveiled upregulation of COX‐related (PGF2a, 8‐iso‐PGF2a and PGF2) and LOX‐related (LTB4, LTD4, 12S‐HETE and 15S‐HETE) factors in HFD‐treated KO mice. Immunohistochemistry and transcriptional analyses showed that miR‐30a‐5p affected arachidonic acid metabolism through the LOX/COX pathways. Besides, COX/LOX pathways and hepatic steatosis were reversed after reintroducing miR‐30a‐5p in HFD‐treated KO mice.ConclusionsThis study reveals the pivotal mechanism by which miR‐30a‐5p and intestinal microbes regulate hepatic steatosis and abnormal lipid metabolism, offering promising avenues for NAFLD and atherosclerosis therapeutics.HighlightsMiR‐30a‐5p deletion aggravated hepatic steatosis and lipid disorder induced by an HFD in mice. Gut microbiota participated in the regulation of hepatic steatosis in the context of miR‐30a‐5p. Gut microbiota metabolism‐related arachidonic acid metabolic pathway contributed to miR‐30a‐5p‐regulated hepatic steatosis and lipid disorder. Reintroducing miR‐30a‐5p reversed hepatic steatosis and arachidonic acid metabolism disorder caused by HFD and miR‐30a‐5p deletion.
