Published: July 2024

AbstractDue to the extended conjugation along the polymeric backbone and the scarcity of suitable multi‐resonance (MR) emitting units for polymerization, precisely adjusting the colors of MR‐thermally activated delayed fluorescence (MR‐TADF) conjugated polymers to green and red region remains to be a formidable challenge. Herein, this work develops a series of green MR‐TADF polymers for the first time by attaching MR emitting moiety as pendant to an acceptor triphenyltriazine while simultaneously embedding acceptor moiety into polycarbazole backbone. Benefitting from the enhanced intramolecular charge transfer (ICT) interaction by introducing acceptor on the para‐carbon position of boron (B) atom of the MR unit, as well as extended conjugation along backbone, all polymers exhibit red‐shifted emissions with emission peaks of 505–517 nm and full‐width at half maximums (FWHMs) of below 48 nm compared to the pendant bluish‐green MR unit peaking at 484 nm. The solution‐processed devices based on these polymers exhibit excellent performances with maximum quantum efficiency (EQE) of 22.2%, emission peak at 511 nm and FWHM of 44 nm, which represents the state‐of‐the‐art performance among the MR‐TADF polymer‐based narrowband OLEDs.

AbstractThe growing volume of spent lithium‐ion batteries (LIBs) with degraded LiCoO2 (D‐LCO) cathodes is arising as an environmental concern as well as a waste of strategic resources. Current recycling strategies for D‐LCO materials primarily focus on metal extractions (Li and Co), which produce large quantities of wastewater and waste residues and consume substantial amounts of energy. Inspiringly, the rapid proliferation of electric vehicles has catalyzed the ever‐increasing production of LIBs with ternary layered oxides as the prevalent cathode materials. Herein, this work reports a simple, green, and economic upcycling strategy for direct transformation of D‐LCO into high‐performance single‐crystal LiNi1/3Co1/3Mn1/3O2 (NCM111) cathode materials. By simultaneous lithium replenishment, particle size reduction, and chemical composition engineering in the upcycling process, the NCM111 product delivers a high specific capacity (159.0 mAh g−1 at 0.1 C) and an excellent cycling stability (82.1% retention after 200 cycles at 1 C), outperforming those of commercial materials. This work highlights the immense potential of upcycling strategies in mitigating the environmental ramifications of spent LIBs and paves the way for the sustainable development of LIBs industry.

AbstractAdvanced conductive hydrogels demonstrate substantial potential for wearable devices. Nevertheless, the transformative advance in soft electronics raises harsh requirements on the hydrogel candidates, such as rapid and on‐site fabrication, mechanical flexibility, high sensitivity, and wide use temperature. Here, this problem is overcome by incorporating a dual catalytic system based on lignin‐modified MXene‐Fe3+ into commercial hydrogels. This system 1) can form a composite hydrogel in a time scale of min at ambient condition without the supply of external energy, 2) incorporates multiple enhanced strategies into polymer chains, and 3) constructs well‐organized hybrid conductive network. The fabricated hydrogel displays an improved and balanced overall performance, including high ductility (2139%), moderate electrical conductivity, and strong temperature tolerance (−70–50 °C). Combined with the great merits of above performance, the hydrogel‐based sensor with good sensing (maximum GF: 2.8), stable repeatability (200% for 200 cycles), and wide work window of 0%–947%, thereby disclosing promising application in physiological movements, such as motion recognition and breathing state detection. Sensationally, even in complex or harsh surroundings, the sensors also produce stable and reliable signal output. Together, the strategy provides a new mentality of designing hydrogel materials for booming and advanced wearable electronics.

Published: July 2024

AbstractDue to repeated microbial infection, persistent inflammation, excessive oxidative stress, and cell dysfunction, chronic wounds are difficult to heal, posing a serious threat to public health. Therefore, developing multifunctional wound dressings that can regulate the complex microenvironment of chronic wounds and enhance cellular function holds great significance. Recently, chitosan has emerged as a promising biopolymer for wound healing due to its excellent biocompatibility, biodegradability, and versatile bioactivity. The aim of this review is to provide a comprehensive understanding of the mechanisms of delayed chronic wound healing and discuss the healing–promoting properties of chitosan and its derivatives, such as good biocompatibility, antibacterial activity, hemostatic capacity, and the ability to promote tissue regeneration. On this basis, the potential applications of chitosan‐based hydrogels are summarized in chronic wound healing, including providing a suitable microenvironment, eliminating bacterial infections, promoting hemostasis, inhibiting chronic inflammation, alleviating oxidative stress, and promoting tissue regeneration. In addition, the concerns and perspectives for the clinical application of chitosan‐based hydrogels are also discussed.

AbstractDNA nanotechnology combines structural design with therapeutic functions via programmable DNA motifs, but faces challenges in drug loading capacity. Herein a pore‐engineering strategy is reported to develop a highly porous, universal DNA nano‐vehicle through coordination self‐assembly, cryo‐engineering, and supramolecular chemistry, adapting to diverse cargo loading with desired theranostic agents. Thus, the complex synthesis and compatibility challenges typically associated with switching between different drug carriers are avoided. To this end, Cu2+ and nucleic acid therapeutic G3139 self‐assemble into a prefabricated solid nanostructure, which subsequently undergoes ultrafast freezing and sublimation to introduce porosity, forming highly porous Cu‐G3139 nanoparticles (CG NPs). The porous CG NPs efficiently accommodate diverse therapeutic molecules, from chemotherapeutics to non‐chemotherapeutic agents, facilitated by positively‐charged cyclodextrin. As a proof‐of‐concept, the photosensitizer indocyanine green (ICG) is loaded and coated with tannic acid (TA) to form CICG@TA, enabling remarkable photothermal and fluorescence imaging‐guided synergistic tumor ablation. This work represents the first demonstration of sublimation‐induced pore formation in metal‐DNA hybrid nanoparticles without chemical etching, offering a scalable “plug‐and‐play” platform for personalized cancer therapy without redesign. This versatile pore‐engineering strategy, merging supramolecular chemistry with cryo‐engineered porosity, opens up new avenues for efficient, customized multidrug delivery for diverse tumor theranostic applications.

Published: July 2024

AbstractAdvances in stem cell technologies, revolutionizing regenerative therapies and advanced in vitro testing, require novel cell manufacturing pipelines able to cope with scale up and parallelization. Microdroplet technologies, which have transformed single cell sequencing and other cell‐based assays, are attractive in this context, but the inherent soft mechanics of liquid‐liquid interfaces is typically thought to be incompatible with the expansion of induced pluripotent stem cells (iPSCs), and their differentiation. In this work, the design of protein nanosheets stabilizing liquid‐liquid interfaces and enabling the adhesion, expansion and retention of stemness by iPSCs is reported. Microdroplet microfluidic chips are used to control the formulation of droplets with defined dimensions and size distributions. The resulting emulsions sustain high expansion rates, with excellent retention of stem cell marker expression. iPSCs cultured in such conditions retain the capacity to differentiate into cardiomyocytes. This work provides clear evidence that local nanoscale mechanics, associated with interfacial viscoelasticity, provides strong cues able to regulate and maintain pluripotency, as well as to support commitment in defined differentiation conditions. Microdroplet technologies appear as attractive candidates to transform cell manufacturing pipelines, bypassing significant hurdles paused by solid substrates and microcarriers.

AbstractManipulation of wavefront lies at the core of next‐generation information technologies. Compared to metal and dielectric metasurfaces, atomic 2D materials exhibit excellent prospects toward fulfilling ultra‐thin thickness requirements in flat optics in wavefront shaping, with thickness much smaller than those of traditional bulky devices. However, phase manipulation by light propagating through atomic 2D materials is suppressed due to its sub‐nanometer thickness. Here, an approach is reported to realize reflection phase singularities by establishing a zero‐reflection point in a monolayer MoS2‐based multilayer system, which broadens topological study beyond polarization singularity. This is achieved through the creation of a multilayer Fabry‐Perot‐type interference, and a pronounced phase change in the reflected light is realized due to the high absorption of monolayer MoS2 in the studied wavelength range. As an application, a rapid, sensitive, and label‐free detection of SARS‐CoV‐2 (2019‐nCov) antigen is demonstrated with a detection limit of 10−12 M L−1 (62 pg ml−1) by using monolayer MoS2 based optical biosensor. In addition to offering a comprehensive study in phase singularity, efficient wavefront engineering based on the reflective system using materials is presented with atomic thickness which may greatly simplify optical architecture in flat optics, and promote its development toward compactness and integrated functions.

AbstractAll‐solid‐state lithium batteries using solid electrolytes hold promise for enhancing energy density. However, some electrolytes with high ionic conductivity are declared unusable because they failed to show compatible with the anode, cathode or even worse, both. Herein, it simultaneously introduced doping and interfacial tuning to prepare fast ion conductor LiBH4‐MgO‐MgI2, which can achieve an ionic conductivity of 1.45 × 10−4 S cm−1 at 50 °C. This electrolyte has the usable ionic conductivity near room temperature, but faces the most extreme challenge of instability at both the lithium anode and high‐voltage cathode. Targeted solution strategies is proposed to return this electrolyte to serviceability. The physical isolation and lithium alloy is employed to solve the lithium anode issue, while the bilayer electrolyte design is applied to the high voltage cathode issue. The LiCoO2|Li3InCl6|LiBH4‐MgO‐MgI2|C|Li and LiCoO2|Li3InCl6|LiBH4‐MgO‐MgI2|LiAl, cycled upon 25 cycles at 0.1 C, achieving reversible capacities of 70 and 90 mAh g−1, respectively. With the targeted solutions for ionic conductivity, anode and cathode compatibility, it will pave the way for commercial application for hydride electrolytes.

Published: July 2024

AbstractEstrogen‐related receptors (ERRs), genes similar to estrogen receptors, are identified as hormone‐responsive systems associated with the ERR subfamily. These hormone‐responsive systems facilitate oncometabolic programs to nourish cancer cell growth, a central node at the interface of cellular energy metabolism and cancer. Several independent studies have implicated ERR isoforms like ERRα, ERRβ, and ERRγ in the pathways of cancer development and progression. The construction of tissue‐specific ERR transgenic or knockout mice and the application of synthetic ligands have precisely indicated the critical and diverse role of ERRγ than other isoforms. ERRγ, plays a critical and diverse role, enabling switching metabolism to oncometabolism in favor of cancer cells, making it a “hot target” in cancer therapy. ERRγ expression is correlated with the clinical status of diverse cancer types and various cancer tissue treatments. The dual feature of ERRγ raises interest in understanding its biogenesis and function in different tissues. This review aims to describe the structural organization of ERRs, their central occupancy at the interface of cancer and metabolism, and their biogenesis and expression profile across different cancers. It concludes that ERRγ has potential as a clinical marker in cancer prognosis and a novel non‐conventional therapeutic target.

Published: July 2024

Abstractδ‐MnO2 has been vigorously developed as an ideal cathode material for rechargeable aqueous zinc‐ion batteries (AZIBs) due to its spacious layer spacing suitable for ion storage. However, poor intrinsic conductivity, structural collapse, and sluggish reaction kinetics are major limitations restricting their battery performance. Doping engineering has been proven to be an effective strategy for modifying the structure, conductivity, and electronic properties of Mn‐based oxides. Here, a series of δ‐MnO2 hierarchical flowers with different cerium‐doped sites are proposed as high‐performance cathodes for AZIBs, revealing the effects of various Ce doping sites on the MnO2 layer‐by‐layer structure and battery performance. Chemical analysis and theoretical calculations indicate that δ‐MnO2 with both in‐layer and interlayer Ce doping (Cein/inter‐MnO2) allows for sufficient Zn2+ storage sites, higher conductivity, and enhanced reaction kinetics due to enlarged interlayer spacing, increased oxygen defects, and reduced Coulombic repulsion between zinc ions and manganese oxide hosts. As a result, Cein/inter‐MnO2 with extended ion transfer channels and sturdy structure delivers a superior capacity of 348.8 mAh g−1 at a current density of 300 mA g−1 over 100 cycles, and a high retention rate of ≈100% at a current density of 3000 mA g−1 over 2000 cycles.

AbstractObjectivesVisceral adipose tissue (VAT) is highly associated with metabolic syndrome (MetS), which is rapidly increasing in young adults. However, accessible VAT measurement methods are limited, restricting the use of VAT in early detection. This cross‐sectional study sought to determine if near‐infrared reactance spectroscopy (NIRS)‐derived VAT (VATNIRS) was associated with MetS in a multi‐ethnic sample of young adults.MethodsA total of 107 male and female (F:62, M:45) participants (age: 23.0 ± 4.3y; BMI: 27.1 ± 6.6 kg/m2) completed measurements of fasting blood pressure, blood glucose (FBG), blood lipids, and anthropometric assessments including waist circumference and VATNIRS. MetS severity (MetSindex) was calculated from the aforementioned risk factors using sex and race‐specific equations.ResultsVATNIRS was higher in participants with, and at risk for, MetS compared to those with lower risks (all p < .001). VATNIRS was positively associated with MetSindex for all groups (all p < .001). VATNIRS showed positive associations with systolic (SBP), diastolic (DBP), and mean arterial pressure (MAP), LDL‐C and LDL‐C‐related biomarkers, and FBG; and negative associations with HDL‐C and HDL‐C‐to‐total cholesterol ratio (all p < .050). Associations between VATNIRS and blood pressure for females, and LDL‐C and LDL‐C‐related biomarkers for males, were nonsignificant (all p > .050). VATNIRS was positively associated with DBP in African–American participants, and SBP in White participants, resulting in positive associations with MAP for both groups (all p < .050).ConclusionsVATNIRS is associated with MetS and individual MetS risks factors in a multi‐ethnic sample of young adults; providing a noninvasive, cost‐effective, portable, and accessible method that may assist in the early detection of MetS and other cardiometabolic abnormalities.

AbstractObjectivesJustinian plague and its subsequent outbreaks were major events influencing Early Medieval Europe. One of the affected communities was the population of Saint‐Doulchard in France, where plague victim burials were concentrated in a cemetery enclosure ditch. This study aimed to obtain more information about their life‐histories using the tools of isotope analysis.Materials and MethodsDietary analysis using carbon and nitrogen isotopes was conducted on 97 individuals buried at Le Pressoir in Saint‐Doulchard, with 36 of those originating from the enclosure ditch. This sample set includes all individuals analyzed for plague DNA in a previous study. Mobility analysis using strontium isotope analysis supplements the dietary study, with 47 analyzed humans. The results are supported by a reference sample set of 31 animal specimens for dietary analysis and 9 for mobility analysis.ResultsThe dietary analysis results showed significantly different dietary behavior in individuals from the ditch burials, with better access to higher quality foods richer in animal protein.87Sr/86Sr ratios are similar for both studied groups and indicate a shared or similar area of origin.DiscussionThe results suggest that the ditch burials contain an urban population from the nearby city of Bourges, which overall had a better diet than the rural population from Saint‐Doulchard. It is implied that city's population might have been subjected to high mortality rates during the plague outbreak(s), which led to their interment in nearby rural cemeteries.

AbstractAny pure state of a compound system with the state space determines a kind of covariance operator acting in the Cartesian product . If this operator is positively defined, then it determines a random field valued in . In this case compound quantum system can be treated as a classical random field system whose configuration space is not tensor, but Cartesian product space. It happens that and a subquantum process exists if and only if quantum state is not entangled. The technical framework used in this note is already presented by von Neumann.

AbstractSynthetic biohybrid systems by coupling artificial system with nature's machinery may offer a disruptive solution to address the global energy crisis. We developed a versatile electroenzymatic pathway for the continuous synthesis of valuable chemicals, facilitated by formate‐driven NADH regeneration. Utilizing a bismuth electrocatalyst, we achieved stable CO2 reduction to formate with approximately 90 % Faraday efficiency at a current density of 150 mA cm−2. The generated formate acts as a mediator to regenerate NADH, which is then coupled with immobilized redox enzymes—alcohol dehydrogenase (ADH), L‐lactate dehydrogenase (LDH), and L‐glutamate dehydrogenase (GDH)—to produce targeted chemicals at significant rates and exceptionally high turnover numbers (1.8×106 to 3.1×106). These achievements not only underscore the efficiency of the system but also its practical applicability in industrial settings. By leveraging in situ generated formate, this innovative approach demonstrates the potential of integrating electrocatalysis with enzymatic reactions for sustainable and efficient chemical production on a practical scale.
