AbstractMagnetic semimetals have increasingly emerged as lucrative platforms hosting spin‐based topological phenomena in real and momentum spaces. Cr1+δTe2 is a self‐intercalated magnetic transition metal dichalcogenide (TMD), which exhibits topological magnetism and tunable electron filling. While recent studies have explored real‐space Berry curvature effects, similar considerations of momentum‐space Berry curvature are lacking. Here, the electronic structure and transport properties of epitaxial Cr1+δTe2 thin films are systematically investigated over a range of doping, δ (0.33 – 0.71). Spectroscopic experiments reveal the presence of a characteristic semi‐metallic band region, which shows a rigid like energy shift with δ. Transport experiments show that the intrinsic component of the anomalous Hall effect (AHE) is sizable and undergoes a sign flip across δ. Finally, density functional theory calculations establish a link between the doping evolution of the band structure and AHE: the AHE sign flip is shown to emerge from the sign change of the Berry curvature, as the semi‐metallic band region crosses the Fermi energy. These findings underscore the increasing relevance of momentum‐space Berry curvature in magnetic TMDs and provide a unique platform for intertwining topological physics in real and momentum spaces.

AbstractIt is demonstrated that the postfunctionalization of solid polymeric microspheres can generate fully and throughout functionalized materials, contrary to the expectation that core–shell structures are generated. The full functionalization is illustrated on the example of photochemically generated microspheres, which are subsequently transformed into polyradical systems. Given the all‐organic nature of the functionalized microspheres, characterization methods with high analytical sensitivity and spatial resolution are pioneered by directly visualizing the inner chemical distribution of the postfunctionalized microspheres based on characteristic electron energy loss signals in transmission electron microscopy (TEM). Specifically, ultrasonic ultramicrotomy is combined successfully with electron energy loss spectroscopy (EELS) and electron spectroscopic imaging (ESI) during TEM. These findings open a key avenue for analyzing all‐organic low‐contrast soft‐matter material structures, while the specifically investigated system concomitantly holds promise as an all‐radical solid‐state functional material.
Rationally Designed CeO2 Nanosheets over Co9S8 Nanoparticles form S‐Scheme Heterojunction for Efficient Hydrogen Production
Authors: Yang Mengxue , Li Youji , Jin Zhiliang 
Published: January 2023

AbstractEnriching the active sites of catalysts and artificially regulating the directional migration of photogenerated carriers are effective means to improve the catalytic activity of photocatalysts. In this work, CeO2 nanosheets are prepared by calcination at high temperatures, and the S‐scheme heterojunction photocatalyst CeO2@Co9S8 is prepared by coupling the Co9S8 nanoparticles prepared by hydrothermal method on CeO2 nanosheets. The large specific surface area of CeO2 nanosheets provides sufficient loading sites for Co9S8 and Co9S8 nanoparticles can effectively disperse with the help of CeO2 nanosheet structure, which effectively inhibits the agglomeration of nanoparticles. The high photosensitivity of Co9S8 increases the utilization of CeO2@Co9S8 S‐scheme heterojunction to visible light. The construction of S‐scheme heterojunction improves the separation efficiency of photogenerated carriers, prolongs the service life of photogenerated charges, retains the photogenerated electrons and holes with strong reduction and oxidation ability in the catalyst system, and improves the performance of photocatalytic hydrogen production. The hydrogen yield of 15 wt% Co9S8 supported CeO2@Co9S8 can reach 15.7 times CeO2 and 2.5 times Co9S8, and the composite catalyst has good stability. This work provides a new way for adjusting the surface structure and carrier behavior of photocatalysts.

AbstractCreating a cellular model of Alzheimer's disease (AD) that accurately recapitulates disease pathology has been a longstanding challenge. Recent studies showed that human AD neural cells, integrated into three‐dimensional (3D) hydrogel matrix, display key features of AD neuropathology. Like in the human brain, the extracellular matrix (ECM) plays a critical role in determining the rate of neuropathogenesis in hydrogel‐based 3D cellular models. Aging, the greatest risk factor for AD, significantly alters brain ECM properties. Therefore, it is important to understand how age‐associated changes in ECM affect accumulation of pathogenic molecules, neuroinflammation, and neurodegeneration in AD patients and in vitro models. In this review, mechanistic hypotheses is presented to address the impact of the ECM properties and their changes with aging on AD and AD‐related dementias. Altered ECM characteristics in aged brains, including matrix stiffness, pore size, and composition, will contribute to disease pathogenesis by modulating the accumulation, propagation, and spreading of pathogenic molecules of AD. Emerging hydrogel‐based disease models with differing ECM properties provide an exciting opportunity to study the impact of brain ECM aging on AD pathogenesis, providing novel mechanistic insights. Understanding the role of ECM aging in AD pathogenesis should also improve modeling AD in 3D hydrogel systems.
Metastable Cubic Structure Exceeds Capacity Limit of Antifluorite Li5FeO4 Cathode Using Small Polarized Oxygen Redox

Published: January 2023

AbstractCost‐effective Fe‐based cathode materials have attracted significant attention. Recently, antifluorite‐type Li5FeO4 has been investigated as a high‐capacity cathode material owing to its high lithium content and solid‐state oxygen redox reactions. However, its reversible capacity is restricted to transition‐metal redox reactions because of its irreversible structural transformation and oxygen evolution. This study demonstrates the reversible oxygen redox reaction in metastable cubic antifluorite Li5FeO4 obtained by mechanochemical treatment. It exhibits a reversible capacity of more than 300 mAh g‐1, corresponding to an approximately 1.7‐electron reaction, without oxygen gas evolution. Combined analyses of X‐ray absorption spectroscopy (XAS) and theoretical calculations reveal that both Fe3+/Fe4+ and O2‐/O22‐ redox reactions proceed under semi‐coherent structural transformations between antifluorite and rocksalt, which differs from the known orthorhombic Li5FeO4 phase. Although the cyclability of oxygen redox is poor, its solid solution with Co2+ enhances cyclability by suppressing oxygen evolution. Tuning the structural symmetry and transition‐metal content can overcome the reversible capacity limit of antifluorite cathode materials, which is useful for the development of high‐energy cathode materials by the effective utilization of solid‐state oxygen redox reactions.

Published: January 2023

AbstractLithium is perceived as an ideal anode for next generation batteries with high‐energy density. However, the critical issue of the intractable growth of Li dendrites, which leads to a poor cycling life, still remains. Herein, a hierarchical surface is designed and constructed on carbon fiber (CF) using binders in fabricated CF paper (CFP). The lightweight CF with high mechanical properties is facilitated to establish a 3D network structure as an alternative to Cu foil. The binders are transformed into oxygen‐containing amorphous carbon and sodium carbonate (Na2CO3) using a low‐temperature carbonization process, leading to uniform Li nucleation and a stable solid electrolyte interphase layer with inorganic components. In the electrochemical test, the CFP with amorphous carbon and Na2CO3 (ANCFP) shows a low Li nucleation overpotential and smooth dendrite‐free Li plating. Furthermore, the ANCFP electrode exhibits good cycling stability in half and symmetrical cells. A full‐cell assembled using a LiFePO4 cathode with high loading (≈13 mg cm−2) achieves a high‐energy density of 428 Wh kg−1 (at 0.1 C) and an excellent capacity retention of 85% at 1 C after 300 cycles. This strategy is expected to help realize highly stable Li metal anodes for practical application by suppressing Li dendrite growth.
Simia langobardorum: Were African apes traded in late medieval Lombardy?

Published: January 2023

AbstractDepictions of and references to apes (tailless hominoids) are very limited in early historical written accounts. The first known published representations of ape‐like primates appear in Medieval European books during the first century following the invention of printing. Considering the current knowledge of ape iconography, this article examines an unusual image of a couple of ape‐like creatures rendered in a European manuscript and explores the possible links of this challenging illustration with historical accounts and contexts during the late Middle Ages and early Renaissance. The studied manuscript is known as “BL Sloane MS 4016” and is a medieval herbal manuscript (Tratactus de Herbis) of Lombardian origin datedc. 1440. The illustration in question, which also appears in similar manuscripts, represents two primates. However, these representations differ significantly from those in the other manuscripts. The individuals have physical features that suggest attribution to chimpanzees. The location and the date of the manuscript in relation to the extended merchant and travel network between Europe and Africa during the late Medieval times and earlier Renaissance most likely indicate that free‐living or traded chimpanzees or their images may have been the visual source for the illustration. The examination of early depictions and descriptions of apes helps us to understand how we, humans, have represented our own closest zoological relatives. In doing so, this study also provides a review of early ape iconography and historical accounts about African primates during the so‐called Age of Discoveries.

ObjectiveTime from stroke onset to reperfusion (TSOR) is strongly associated with outcomes after endovascular treatment. A near‐to‐complete or complete reperfusion (modified Treatment in Cerebral Ischemia [mTICI] 2c–3) is associated with improved outcomes compared with a successful reperfusion (mTICI 2b). However, it is unknown whether this association remains stable as TSOR increases. Therefore, we sought to investigate the association between TSOR and outcomes according to the reperfusion status.MethodsWe analyzed data from the Endovascular Treatment in Ischemic Stroke registry, a prospective, observational, multicentric study of acute ischemic stroke patients treated with endovascular treatment in 21 centers in France. We included patients with anterior occlusions (M1, internal carotid artery, tandem), with a known time of symptom onset. Outcomes were early neurological improvement at 24 hours and favorable outcome (modified Rankin Scale between 0 and 2) at 90 days.ResultsOverall, 4,444 patients were analyzed. Compared with a mTICI 2b, a mTICI 2c‐3 at 1 hour was associated with higher mean marginal probabilities of early neurological improvement (25.6%, 95% CI 11.7–39.5, p = 0.0003) and favorable outcome (15.2%, 95% CI 3.0–27.4, p = 0.0143), and progressively declined with TSOR. The benefit of a mTICI 2c‐3 over a mTICI 2b was no longer significant regarding the rates of early neurological improvement and favorable outcome after a TSOR of 414 and 344 minutes, respectively.InterpretationThe prognostic value of a complete over a successful reperfusion progressively declined with time, and no difference regarding the rates of favorable outcome was observed between a complete and successful reperfusion beyond 5.7 hours.

AbstractHyperbranched polymethacrylates were synthesized by green‐light‐induced atom transfer radical polymerization (ATRP) under biologically relevant conditions in the open air. Sodium 2‐bromoacrylate (SBA) was prepared in situ from commercially available 2‐bromoacrylic acid and used as a water‐soluble inibramer to induce branching during the copolymerization of methacrylate monomers. As a result, well‐defined branched polymethacrylates were obtained in less than 30 min with predetermined molecular weights (36 000<Mn<170 000), tunable degree of branching, and low dispersity values (1.14≤Đ≤1.33). Moreover, the use of SBA inibramer enabled the synthesis of bioconjugates with a well‐controlled branched architecture.
Biotechnological Frontiers of DNA Nanomaterials Continue to Expand: Bacterial Infection using Virus‐Inspired Capsids
Authors: Bastings Maartje M. C. 
Published: January 2023

AbstractThe elegant geometry of viruses has inspired bio‐engineers to synthetically explore the self‐assembly of polyhedral capsids employed to protect new cargo or change an enzymatic microenvironment. Recently, Yang and co‐workers used DNA nanotechnology to revisit the icosahedral capsid structure of the phiX174 bacteriophage and reloaded the original viral genome as cargo into their fully synthetic architecture. Surprisingly, when using a favorable combination of structural rigidity and dynamic multivalent cargo entrapment, the synthetic particles were able to infect non‐competent bacterial cells and produce the original phiX174 bacteriophage. This work presents an exciting new direction of DNA nanotech for bio‐engineering applications which involve bacterial interactions.

Published: January 2023

AbstractWearable bioelectronics is a promising next‐generation technology for its versatility in personalized applications. Measuring lactate is one of the growing trends in wearable biosensing research. To achieve this goal, enzymes capable of catalyzing reactions involving lactate must be coupled with bioelectrode components, creating a variety of biodevices such as biosensors, biofuel cells, and other devices harvesting energy from wearers. This review provides a brief history of noninvasive and minimally invasive enzyme‐based lactate biosensors and energy biodevices. We introduce key principles of lactate oxidase and lactate dehydrogenase, together with immobilization strategies for efficient electrical contacts between redox enzymes and electrode supports. Additionally, we discuss recent examples of advanced wearable enzymatic lactate sensors and elaborate on a collection of self‐powered wearable energy biodevices (e. g., biofuel cells, triboelectric nanogenerators, and piezoelectric devices). Lastly, we finish this review with discussions on challenges in developing lactate bioelectronics and provide our outlook on the prospects and future directions of this compelling technology.

Published: January 2023

Abstractγ‐Linolenic acid (GLA) rich triacylglycerol (TAG) was successfully synthesized from glyceride, instead of glycerol, and fatty acid (FA) via Lipozyme TL IM‐catalyzed esterification as a novel strategy. In the first step, GLA was enriched into glyceride fraction from borage oil by Candida rugosa lipase‐catalyzed hydrolysis. The glyceride was separated from the reaction mixture by molecular distillation. GLA was enriched from 20.64% in borage oil to 45.94% in the glyceride fraction under optimum conditions. In the second step, the Lipozyme TL IM‐catalyzed synthesis of TAG was carried out with the glyceride, and the FA obtained by saponification of a portion of the glyceride. The optimum conditions were the temperature of 50°C, the enzyme loading of 10%, and the vacuum level of 20 mmHg, respectively. The maximum TAG content of approximately 92% was achieved after 12 h under the optimum conditions.

Published: January 2023

AbstractIn this paper, l‐lysine (Lys), l‐glutamate (Glu), and l‐glutamine (Gln) grafted‐chitosan (CS) polymers (AA‐g‐CS) are prepared by the one‐pot method using EDC/NHS as coupling agents. The introduction of AA into the backbone structure of CS improves its solubility in the pH range of 6.0–7.0. Moreover, AA‐g‐CS/glycerophosphate hydrogel (AA‐g‐CS/GP hydrogel) prepared by physical cross‐linking has better thermosensitivity and can achieve the sol–gel transition in very short order. AA‐g‐CS/GP hydrogel has a dense three‐dimensional network structure, conducing to the loading of the hydrophobic drugs, and its pore size and pore wall are affected by Lys, Glu, and Gln. Berberine hydrochloride (BBH) is encapsulated within the three‐dimensional mesh of the hydrogel. And the addition of BBH has no significant effect on the structure of AA‐g‐CS/GP hydrogel. The optimal parameters for AA‐g‐CS/GP hydrogel loaded BBH (BBH@AA‐g‐CS/GP hydrogel) are the concentration of AA‐g‐CS is 4.5% and the volume ratio of AA‐g‐CS/GP is 1.4/0.6. It is shown that BBH@Lys‐g‐CS/GP hydrogel, BBH@Glu‐g‐CS/GP hydrogel, and BBH@Gln‐g‐CS/GP hydrogel have better‐sustained release effect. Moreover, the sustained release of BBH@Lys‐g‐CS/GP hydrogel is the best, and the cumulative release rate is about 56% in 24 h. Therefore, AA‐g‐CS/GP thermosensitive hydrogel is expected to be an excellent vehicle for sustained release of drugs.

Published: January 2023

AbstractCopper is a key metal for carbon dioxide (CO2) reduction reaction, which can reduce CO2 to value‐added products. The core‐shell structure can effectively promote the C−C coupling process due to its strong synergistic effect originated from its unique electronic structure and interface environment. Therefore, the combination of copper and core‐shell structure to design an efficient Cu‐based core‐shell structure catalyst is of great significance for electrocatalytic CO2 reduction (CO2RR). In this review, we first briefly summarize the basic principle of CO2RR. In addition, we outline the advantages of core‐shell structure for catalysis. Then, we review the recent research progresses of Cu‐based core‐shell structures for the selective reduction of multi‐carbon (C2+) products. In the end, the challenges of using core‐shell catalyst for CO2RR are described, and the future development of this field is prospected.

AbstractThis paper considers discrete‐time mean field linear quadratic games with multiplicative noises, where the weighting matrices in the cost functions are allowed to be indefinite. First, by expanding the dimension of the systems, we present the necessary and sufficient condition for the existence of Nash equilibrium. Second, by solving the limiting optimal control problem, we design a set of decentralized control strategies, which is shown to be an
‐Nash equilibrium. Finally, a numerical example is given to illustrate the effectiveness of the proposed control strategies.

Published: January 2023

AbstractPoor sleep can have a significant impact on physical health and well‐being. Sleep problems are common among autistic children, but less is known about sleep across the autistic adult lifespan. Autistic adults (n = 730, aged 18–78 years) were recruited via Simons Powering Autism Research for Knowledge Research Match. Participants completed online surveys asking about demographics, health problems, social support, symptoms of anxiety and depression, and overall and specific aspects of sleep quality. Regression analyses explored the variables associated with sleep quality. Physical health, assigned female sex at birth and self‐reported anxiety symptoms significantly contributed to models for all aspects of sleep. Perceived stress contributed to models of overall and subjective sleep quality, and daytime dysfunction. Depression symptoms did not contribute significantly to any of the models of sleep quality. However, utilizing government support mechanisms (such as social security) contributed to the model of sleep efficiency. Age contributed little to models of sleep quality, whereas perceived stress and psychotropic medication use contributed to some but not all aspects of sleep. Sleep quality is poor for autistic people across the adult lifespan. Given known impacts of poor sleep on health, cognition and quality of life, attention should be paid to sleep and its possible everyday effects for autistic people of all ages.
