AbstractScaling up superconducting quantum circuits based on transmon qubits necessitates substantial enhancements in qubit coherence time. Over recent years, tantalum (Ta) has emerged as a promising candidate for transmon qubits, surpassing conventional counterparts in terms of coherence time. However, amorphous surface Ta oxide layer may introduce dielectric loss, ultimately placing a limit on the coherence time. In this study, a novel approach for suppressing the formation of tantalum oxide using an ultrathin magnesium (Mg) capping layer is presented. Synchrotron‐based X‐ray photoelectron spectroscopy studies demonstrate that oxide is confined to an extremely thin region directly beneath the Mg/Ta interface. Additionally, it is demonstrated that the superconducting properties of thin Ta films are improved following the Mg capping, exhibiting sharper and higher‐temperature transitions to superconductive and magnetically ordered states. Moreover, an atomic‐scale mechanistic understanding of the role of the capping layer in protecting Ta from oxidation is established based on computational modeling. This work provides valuable insights into the formation mechanism and functionality of surface tantalum oxide, as well as a new materials design principle with the potential to reduce dielectric loss in superconducting quantum materials. Ultimately, the findings pave the way for the realization of large‐scale, high‐performance quantum computing systems.

AbstractElectrical stimulation (ES) has shown beneficial effects in repairing injured tissues. However, current ES techniques that use tissue‐traversing leads and bulky external power suppliers have significant limitations in translational medicine. Hence, exploring noninvasive in vivo ES to provide controllable electrical cues in tissue engineering is an imminent necessity. Herein, a conductive hydrogel with in situ electrical generation capability as a biodegradable regeneration scaffold and wireless ES platform for spinal cord injury (SCI) repair is demonstrated. When a soft insulated metal plate is placed on top of the injury site as a wireless power transmitter, the conductive hydrogel implanted at the injury site can serve as a wireless power receiver, and the capacitive coupling between the receiver and transmitter can generate an alternating current in the hydrogel scaffold owing to electrostatic induction effect. In a complete transection model of SCI rats, the implanted conductive hydrogels with capacitive‐coupling in situ ES enhance functional recovery and neural tissue repair by promoting remyelination, accelerating axon regeneration, and facilitating endogenous neural stem cell differentiation. This facile wireless‐powered electroactive‐hydrogel strategy thus offers on‐demand in vivo ES with an adjustable timeline, duration, and strength and holds great promise in translational medicine.

AbstractImproving catalytic activity of surface iridium sites without compromising catalytic stability is the core task of designing more efficient electrocatalysts for oxygen evolution reaction (OER) in acid. This work presents phase transition of a bulk layered iridate Na2IrO3 in acid solution at room temperature, and subsequent exfoliation to produce 2D iridium oxide nanosheets with around 4 nm thickness. The nanosheets consist of OH‐terminated, honeycomb‐type layers of edge‐sharing IrO6 octahedral framework with intrinsic in‐plane iridium deficiency. The nanosheet material is among the most active Ir‐based catalysts reported for acidic OER and gives an iridium mass activity improvement up to a factor of 16.5 over rutile IrO2 nanoparticles. The material also exhibits good catalytic and structural stability and retains the catalytic activity for more than 1300 h. The combined experimental and theoretical results demonstrate that edge Ir sites of the layer are active centers for OER, with structural hydroxyl groups participating in the catalytic cycle of OER via a non‐traditional adsorbate evolution mechanism. The existence of intrinsic in‐plane iridium deficiency is the key to building a unique local environment of edge active sites that have optimal surface oxygen adsorption properties and thereby high catalytic activity.

AbstractNanosecond laser patterning of Copper Metal–Organic Framework (Cu‐MOF) coated substrates is performed to fabricate non‐enzymatic glucose sensing electrodes. The Cu‐MOF coated glass substrate with a cover glass is subjected to a laser patterning process; the amount of MOF, laser fluence, and scan speeds mainly influenced the patterning process. The electrodes are fabricated on coated and covered glass with varying electrical conductivity due to the high laser energy absorptivity. The patterned electrodes consist of graphitic carbon incorporated with nano‐Cu and show a stable electrical conductivity on the coated substrates. The electrodes are chemically active in the Fe2+/Fe3+ redox system; however, their activity varies with patterning conditions. The electrochemical studies in alkaline electrolytes reveal that the as‐fabricated electrodes can sense the glucose molecule in the linear concentration range of 0.025–1.0 and 1.0–10.0 mm, with a maximum sensitivity of 3260.3 µA mM−1 cm−2 and a response time of no more than 5 s, and a limit of detection (LOD) of 0.25 µm. The current recovery rate is higher (> 80%) when adding glucose molecules than when adding other interference molecules, confirming that the electrode is selective toward glucose sensing. The results reveal that the fabricated electrodes act as stable, reusable, non‐enzymatic glucose‐sensing electrodes.

Published: January 2024

AbstractCarbon dots (CDs) have emerged as versatile fluorescent nanomaterials for diverse applications. The synthesis of CDs from natural products offers a sustainable alternative to chemical methods. This study presents the preparation of green fluorescent CDs (G‐CDs) using seafood mushrooms as the carbon source and 5‐amino‐2‐methylphenol as the nitrogen source through a hydrothermal approach. The G‐CDs exhibit maximum excitation/emission peaks at 467/519 nm and a high quantum yield of up to 17.2% in ethanol. Additionally, the G‐CDs demonstrate excellent photostability, salt tolerance, and chemical stability. The excitation‐independent emissions suggest the presence of unique surface‐state luminescent centers. The application of the G‐CDs as an anti‐counterfeiting fluorescent ink is demonstrated. This work highlights the promise of converting natural food sources into high‐performance CDs, expanding their utility across various domains including biomedicine, sensing, and security.

AbstractThe efficiency of perovskite solar cells (PSCs) is hindered by substantial defects within the grain boundaries (GBs) of polycrystalline perovskite films. Conventional post‐treatment strategies struggle to precisely repair these defects at GBs. Here, a targeted grain boundary passivation strategy through solvent effects by incorporating symmetrical biphenyl molecules is proposed, 4,4′‐diaminodiphenyl sulfone (DDS) and 4,4′‐sulfodiphenol (SDP), aiming to mitigate defects at GBs and optimize energy level arrangements through their electric dipole effects. Compared to the pristine device, the SDP‐modified device exhibits significant improvements, including a champion efficiency of 24.39% and an impressive fill factor, along with excellent operation stability. This work provides an effective and straightforward solution for improving the performance of PSCs.

AbstractTuning the morphology through processing additives represents one of the most promising strategies to boost the performance of organic solar cells (OSCs). However, it remains unclear how oligothiophene‐based solid additives influence the molecular packing and performance of OSCs. Here, two additives namely 2T and 4T, are introduced into state‐of‐the‐art PM6:Y6‐based OSCs to understand how they influence the film formation process, nanoscale morphology, and the photovoltaic performance. It is found that the 2T additive can improve the molecular packing of both donor polymer and non‐fullerene acceptor, resulting in lower Urbach energy and reduced energy loss. Furthermore, the blend film with 2T treatment displays enhanced domain purity and a more favorable distribution of the acceptor and donor materials in the vertical direction, which can enhance charge extraction efficiency while simultaneously suppressing charge recombination. Consequently, OSCs processed with 2T additive realize a promising efficiency of 18.1% for PM6:Y6‐based devices. Furthermore, the general applicability of the additive is demonstrated, and an impressive efficiency of 18.6% for PM6:L8‐BO‐based OSCs is achieved. These findings highlight that the uncomplicated oligothiophenes have excellent potential in fine‐adjustment of the active layer morphology, which is crucial for the future development of OSCs.

AbstractBackgroundAnemia has negative effects on long‐term outcomes of rectal cancer patients; however, its status as a risk factor for severe complications is disputed. Perioperative risks may differ based on the severity of pre‐surgical anemia; nonetheless, no previous study has investigated these differences. This study identified risks of severe postoperative complications in rectal cancer patients based on severity of their pre‐surgical anemia.Materials and MethodsThis study enrolled patients who underwent low anterior resection for rectal cancer and were registered in the Japanese National Clinical Database (NCD) between 2017 and 2019. Anemia severity was categorized into three levels: mild, moderate, and severe. A logistic regression model was applied to calculate the risk‐adjusted odds ratio (OR) of severe complications after surgery.ResultsThis study analyzed a cohort of 51 765 rectal cancer patients who underwent low anterior resection. Results showed that severe complications occurred in 10.9% of patients and were significantly more frequent in patients with anemia (13.6%) than those with normal hemoglobin levels (9.2%). Risk‐adjusted ORs of severe complications in the severe, moderate, and mild anemia groups versus the normal group for males were 1.19 (95% confidence interval [CI]: 0.89–1.58), 1.47 (1.34–1.62), and 1.21 (1.12–1.31), respectively. Those for females were 1.39 (0.90–2.15), 1.64 (1.37–1.97), and 1.36 (1.16–1.58), respectively.ConclusionsAccording to this large cohort study, pre‐surgical anemia significantly increases the risk of severe postoperative complications in rectal cancer patients. Even mild anemia presents a significant risk.

AbstractChimeric antigen receptor (CAR) T‐cell therapy, an innovative immunotherapeutic against relapsed/refractory B‐cell lymphoma, faces challenges due to frequent viral infections. Despite this, a comprehensive review addressing risk assessment, surveillance, and treatment management is notably absent. This review elucidates immune response compromises during viral infections in CAR‐T recipients, collates susceptibility risk factors, and deliberates on preventive strategies. In the post‐pandemic era, marked by the Omicron variant, new and severe threats to CAR‐T therapy emerge, necessitating exploration of preventive and treatment measures for COVID‐19. Overall, the review provides recommendations for viral infection prophylaxis and management, enhancing CAR‐T product safety and recipient survival.
New synthetic strategy to create intricate thiaoxacyclophanes via ring‐closing metathesis

Published: January 2024

AbstractThis study explores a thiol‐free, two‐step synthetic strategy to intricate thiacyclophanes from bromoaryl precursors. Our methodology involves a one‐pot substitution reaction of aryl bromides with potassium thioacetate (PTA) followed by ring‐closing metathesis (RCM). Potassium thioacetate is advantageous over other sulfur‐containing reagents like sodium sulfide, sodium hydrosulfide, and sodium hydroxymethylsulfinate (rongalite), etc., as it generates a stable and odorless thioacetate intermediate which allows access to a variety of symmetrical and unsymmetrical sulfides. These sulfides undergo RCM to generate new thiacyclophanes. Applying this methodology, we have created 24 new oxa‐thiacyclophanes and aza‐oxa‐thiacyclophanes containing different aromatic and aliphatic units. The structures and stereochemistry of these cyclophanes are confirmed by NMR data and further supported by single‐crystal X‐ray diffraction data.

Helicoselective Synthesis of Indolohelicenoids through Organocatalytic Central‐to‐Helical Chirality Conversion
Authors: Xu Wen‐Lei , Zhang Ru‐Xia , Wang Hui , Chen Jie , Zhou Ling 
Published: January 2024

AbstractWe report the helicoselective and convergent construction of indolohelicenoids with excellent efficiency and stereocontrol. This reaction proceeds through a chiral‐phosphoric‐acid‐catalyzed enantioselective cycloaddition and eliminative aromatization sequence, which can be finely controlled by adjusting the reaction temperature. Mechanistic studies reveal that the chiral phosphoric acid cooperatively serves as both a bifunctional and Brønsted acid catalyst, enabling one‐pot central‐to‐helical chirality conversion. Additionally, the optical properties of the synthesized indolohelicenoids were characterized to explore their potential applications in organic photoelectric materials.
Detecting benefits of protection level on diversity facets in a sea of temporal scarcity

Published: January 2024

Abstract

The establishment of protected areas to face global diversity declines has mainly prioritized taxonomic diversity, leaving aside phylogenetic and functional diversities, which determine ecosystem functioning and resilience. Furthermore, the assessment of protected areas' effectiveness is mainly done using short‐duration surveys (<2 h), which may undermine the detection of rare species.
Through a long‐duration video approach, reef fish taxonomic, phylogenetic and functional facets of diversity were assessed for 3 days within a fully protected area and a nearby poorly protected area in Mayotte Island (Western Indian Ocean).
We found that temporally rare species contributed to more than 60% of the taxonomic facet and 85% of the functional facet of biodiversity found on each site. Those rare species, which harbour the most distinct trait values, also make reef fish diversity particularly vulnerable to their loss. Taxonomic, phylogenetic and functional richness were similar between the fully protected area and the poorly protected area, while the species, lineage and trait compositions were markedly different.
These results pinpoint the importance of considering taxonomic, functional and phylogenetic dissimilarities while assessing protected areas' effectiveness, instead of using only richness. In addition, benefits of the fully protected area were detected only using more than 15 h of video survey, which emphasizes the importance of long‐duration remote approaches to capture the within‐ and between‐day temporal variations.

ABSTRACTIn 1976, Yosihiko H. Sinoto conducted extensive archaeological survey and excavations on Reao Atoll, Tuamotu Archipelago as part of a Japanese, multi‐disciplinary expedition led by Prof. Sachiko Hatanaka. Primarily excavating three marae and four habitation sites totalling ∼180 m2, more than 25000 vertebrate remains were recovered. We report the jidentification and analysis of the fauna and contrast the inventories from secular and sacred contexts inferring the ritual use of pig, dog, turtle and tuna (Scombridae), as well as identifying relatively larger parrotfish (Scaridae), groupers (Serranidae), snappers (Lutjanidae), the Humphead wrasse (Cheilinus undulatus) and sharks/rays (Elasmobranchii) on marae. With a suite of 11 new AMS age determinations, we report the first directly dated precontact records for pig and dog and anchor the marae chronology possibly beginning in the thirteenth century. The 800 calBP dates imply that at least one of the Tuamotu atolls may have emerged nearly two centuries prior to the hypothesised ‘cross‐over’ date of 600 BP. Consequently, the earliest chronology of atoll emergence along the 1000 km length of the Tuamotus might vary, thus providing landscapes for human colonisation at slightly different times which has implications for the speed and tempo of colonisation.
Social interaction links active musical rhythm engagement and expressive communication in autistic toddlers
Authors: Fram Noah R. , Liu Talia , Lense Miriam D. 
Published: January 2024

AbstractRhythm is implicated in both social and linguistic development. Rhythm perception and production skills are also key vulnerabilities in neurodevelopmental disorders such as autism which impact social communication. However, direct links between musical rhythm engagement and expressive communication in autism is not clearly evident. This absence of a direct connection between rhythm and expressive communication indicates that the mechanism of action between rhythm and expressive communication may recruit other cognitive or developmental factors. We hypothesized that social interactions, including general interpersonal relationships and interactive music‐making involving children and caregivers, were a significant such factor, particularly in autism. To test this, we collected data from parents of autistic and nonautistic children 14–36 months of age, including parent reports of their children's rhythmic musical engagement, general social skills, parent–child musical interactions, and expressive communication skills. Path analysis revealed a system of independent, indirect pathways from rhythmic musical engagement to expressive communication via social skills and parent–child musical interactions in autistic toddlers. Such a system implies both that social and musical interactions represent crucial links between rhythm and language and that different kinds of social interactions play parallel, independent roles linking rhythmic musical engagement with expressive communication skills.

AbstractIntroductionRetrieval practice has been shown to be an effective means of learning new information, a memory phenomenon known as thetesting effector theretrieval practice effect. Some work suggests that the magnitude of the testing effect can be enhanced when the test used for retrieval practice uses fewer cues to retrieve previously studied information. It is unclear, however, whether such testing benefits extend to peripheral contextual details associated with studied materials (e.g., location where stimuli appear, font color in which items are presented, etc.). In this experiment, we examine both item memory (i.e., memory for the studied items) and context memory under conditions where the intervening test offers fewer cues (i.e., lower constraint) compared to more cues (higher constraint) to better understand item and context memory testing effects.MethodsParticipants first studied word pairs presented in one of eight locations as well as in either red or green font color. Then, in the re‐exposure phase, participants processed materials in two types of intervening tests (lower constraint and a higher constraint test) as well as in a restudy condition, before a final memory test.ResultsFor item memory, results showed that memory was better in the lower constraint testing condition compared to both the higher constraint testing condition as well as the restudy (control) condition. For context memory, results indicated improved memory for location context under lower constraint testing compared to both higher constraint testing and restudy conditions. There was no difference in memory, however, for color context across all conditions.ConclusionOverall, these findings suggest that providing fewer cues to aid retrieval in the intervening test can induce better memory for both items as well as some contextual details.
