This study, investigate of ternary thermoplastic fluoropolymer blend nanocomposite (NC) system for improved microwave (MW) shielding, consisting of polyvinyl dimethylamine fluoride (PVDF) and Fe3O4‐multiwalled carbon nanotube (MWCNT) (1:2) NC. Using a hydrothermal process, complex hierarchical nanostructures (NSs) of Fe3O4‐MWCNT (1:2) NC are produced. These NSs are then integrated using a drop‐casting technique into PVDF matrices with different wt% (20, 40, and 60 wt%) and thicknesses (20, 50, and 80 μm). The single‐layer thin films (SLFs) with the Fe3O4‐MWCNT (1:2)‐PVDF matrix are successfully produced as a consequence of this approach. The presence of FeOC bonding from X‐ray photoelectron spectroscopy (XPS) analysis confirms chemical interaction, while scanning electron microscopy (SEM–Energy dispersive spectroscopy EDX) imaging analysis for material homogeneity. Moreover, the SLFs of Fe3O4‐MWCNT (1:2)‐PVDF (20, 40, and 60 wt% for 80 μm thickness) are newly discovered meta‐nanocomposites (MNCs) properties, which are evidenced by negativeMW real complex permittivity (−274.4, −271.2, and −136.4), superior attenuation constant (12862.73, 16265.18, and 12256.34), and higher alternating current (AC)electrical conductivities (1020.8, 1174.6, and 727.7 S m−1). The synergistic impact of higher attenuation and AC conductivity of MNCs results in an increased average MW shielding effectiveness of ≈33.28 dB for Fe3O4‐MWCNT (1:2)‐PVDF 20 wt% MNCs (≈80 μm).

AbstractOptimized sodium ion battery (SIB) carbon anodes with high stability supporting high power densities are a much‐needed material class and therefore intensively researched. The optimum graphitization degree to accommodate sodium ions, while providing high conductivity, as well as the influence of particle size distribution or pore sizes on the performance of carbon anodes, is one of the most discussed topics in this field. While a lot of studies have been published discussing these questions, the convoluted nature of these parameters, originating from material synthesis constraints, usually prevents their independent optimization. Based on Mesoporous N‐doped Carbon Nanospheres (MPNC) as model carbon material systems, the graphitization temperaturefor spherical particles with a monomodal particle size distribution (≈280 nm) and a narrow pore size distribution (≈30 nm) is optimized for faradaic sodium ion storage (plateau capacity) and electrodes with a very high power density of 2680 W kg−1 at 1000 mA g−1 and a remarkable capacity retention over 2000 cycles of 86 %, only losing 0.04 % of its specific capacity per cycle, are demonstrated.

Published: June 2024

AbstractThe pursuit of eco‐friendly electromagnetic wave absorption (EMWA) materials with multifunctional capabilities has garnered significant attention in practical applications. However, achieving these desired qualities simultaneously poses a significant challenge. This study introduces a single‐step calcination and chemical polymerization process to obtain an environmentally friendly ant‐nest‐inspired hybrid composite by optimizing conductive polypyrrole nanotubes (PNTs) within a 3D carbonaceous structure. The biomimetic composite forms a highly efficient conductive network, providing a pathway for free electrons within the carbonaceous barriers and enhancing the conduction loss. Remarkably, the EMWA performance of the composite achieves ultrathin (1.6 mm), wide effective absorption band (5.4 GHz), and strong absorption intensity (−67.6 dB) features. Moreover, due to the complex and intertwined 3D continuous network, the obtained samples exhibit excellent thermal insulation and superhydrophobic behavior by inhibiting heat transfer and preventing localized areas from being prone to water absorption. These findings not only offer a sustainable and low‐cost production route for biomimetic carbonaceous composites but also demonstrate a high‐efficiency absorber with great multifunctionality as a green alternative to traditional EMWA materials.

Published: June 2024

AbstractHydrogels hold great promise in the field of flexible electronics. Attempts in this area tend to the microstructure design of hydrogels, giving them specific adhesion and multi‐sensing functions. Here, a novel phase separation‐derived anisotropic adhesive structural color hydrogel film is presented for visually flexible electronics. The hydrogel film is generated by template replicating colloidal crystal by using phase separation emulsions of hydrophilic monomer (acrylic acid, AA), hydrophobic monomer (lauryl methacrylate, LMA), co‐monomer ([2‐(methacryloyloxy) ethyl] dimethyl‐(3‐sulfopropyl) ammonium hydroxide (SBMA)), surfactants (hexadecyl trimethyl ammonium bromide, CTAB) and initiator (ammonium persulphate (APS)). The appearance of phase separation results in asymmetric morphologies of hydrogel film, imparting them with anisotropic adhesive performance. Attributed to the formation of inverse opal scaffold structure, the hydrogel film is featured with vivid structural color, showing superior capability in self‐reporting mechanical behavior. Additionally, benefitting from the presence of abundant ions, the hydrogel film exhibits great conductivity. Thus, the resultant hydrogel film is demonstrated with stable dual‐signal sensing properties involving color‐changing and conductivity feedback ability to respond to human activities. These features make the proposed anisotropic adhesive structural color hydrogel film highly potential in the flexible electronic field.

AbstractIntegration of solar cells and electrochromic windows offers crucial contributions to green buildings. Solar‐charging zinc anode‐based electrochromic devices (ZECDs) present opportunities for addressing the solar intermittency issue. However, the limited energy storage capacity of ZECDs results in wasted harnessing of solar energy as well as overcharging. Herein, spectral‐selective dual‐band ZECDs that continuously transport solar energy to indoor appliances by remotely controlling the repeated bleached‐tinted cycles during the daytime, are reported. Hexagonal phase cesium‐doped tungsten bronze (h‐Cs0.32WO3, CWO) nanocrystals are adopted for dual‐band ZECDs due to their independent control ability of near‐infrared (NIR) and visible (VIS) light transmittance (∆T = 73.0%, 700 nm; ∆T = 83.7%, 1200 nm) and excellent cycling stability (0.8% optical contrast decay at 1200 nm after 10 000 cycles). The prototype device (i.e., CWO//Zn//CWO) delivers extraordinary thermal insulation capability, displaying a 10 °C difference between “bright” and “dark” modes. Furthermore, an Internet of Things (IoT) controller to control the NIR and VIS lights of the CWO//Zn//CWO window wirelessly with a smartphone, empowering the continuous discharging of the solar‐charged window during the daytime remotely, is developed. Such windows represent an intriguing potential technology whose future impact on green buildings may be substantial.

AbstractThe development of immune cell engagers (ICEs) can be limited by logistical and functional restrictions associated with fusion protein designs, thus limiting immune cell recruitment to solid tumors. Herein, a high affinity superantigen‐based multivalent ICE is developed for simultaneous activation and recruitment of NK and T cells for tumor treatment. Yeast library‐based directed evolution is adopted to identify superantigen variants possessing enhanced binding affinity to immunoreceptors expressed on human T cells and NK cells. High‐affinity superantigens exhibiting improved immune‐stimulatory activities are then incorporated into a superantigen‐based tri‐functional yeast‐display‐enhanced multivalent immune cell engager (STYMIE), which is functionalized with a nanobody, a Neo‐2/15 cytokine, and an Fc domain for tumor targeting, immune stimulation, and prolonged circulation, respectively. Intravenous administration of STYMIE enhances NK and T cell recruitment into solid tumors, leading to enhanced inhibition in multiple tumor models. The study offers design principles for multifunctional ICEs.

AbstractRetention of metabolic end‐products in the bodily fluids of patients with chronic kidney disease (CKD) may lead to uremia. The uremic toxin indoxyl sulfate (IS), a tryptophan metabolite, is an endogenous ligand of aryl hydrocarbon receptor (AhR). It is clarified that the upregulation and activation of AhR by IS in tubular epithelial cells (TECs) promote renal senescence and fibrosis. Renal TEC‐specific knockout of AhR attenuates renal senescence and fibrosis, as well as the suppression of PGC1α‐mediated mitochondrial biogenesis in ischemia reperfusion (IR)‐ or IS‐treated CKD mice kidneys. Overexpression of peroxisome proliferator‐activated receptor gamma coactivator 1‐α (PGC1α) attenuates IS‐induced cell senescence and extracellular matrix production in cultured TECs. Mechanistically, AhR is able to interact with PGC1α and promotes the ubiquitin degradation of PGC1α via its E3 ubiquitin ligase activity. In summary, the elevation and activation of AhR by the accumulated uremic toxins in the progression of CKD accelerate renal senescence and fibrosis by suppressing mitochondrial biogenesis via promoting ubiquitination and proteasomal degradation of PGC1α.
Hybridizing Shear‐Stiffening Gel and Chemically‐Strengthened Ultrathin Glass Sheets for Flexible Impact‐Resistant Armor
Authors: Wang Xuchao , Zhang Zijing , Liang Zhihua , Yao Haimin 
Published: June 2024

AbstractTraditional anti‐impact armors and shields are normally made of stiff and hard materials and therefore deficient in flexibility. This greatly limits their applications in protecting objects with complex geometries or significant deformability. Flexible armors can be developed with the application of hard platelets and soft materials, but the lower rigidity of the flexible armors renders them incapable of providing sufficient resistance against impact attacks. To address the inherent conflict between flexibility and impact resistance in traditional armors, here, a composite is developed by hybridizing a shear‐stiffening gel as the matrix and chemically‐strengthened ultrathin glass sheets (CSGS) as the reinforcement. The resulting laminate, termed PCCL, exhibits both high flexibility and high impact resistance. Specifically, at low strain rates, the high ductility of the gel combined with the high flexural strength of the CSGS enables the PCCL to undergo considerable deformation; at high strain rates, on the other hand, the shear stiffening behavior of the gel matrix endows the PCCL with excellent impact resistance manifested by its high performance in energy absorption and high rigidity. With the combination of high flexibility and high impact resistance, the PCCL is demonstrated to be an ideal armor for protecting curved vulnerable objects from impact attacks.
Noncovalent Interactions‐Driven Self‐Assembly of Polyanionic Additive for Long Anti‐Calendar Aging and High‐Rate Zinc Metal Batteries

Published: June 2024

AbstractZinc anodes of zinc metal batteries suffer from unsatisfactory plating/striping reversibility due to interfacial parasitic reactions and poor Zn2+ mass transfer kinetics. Herein, methoxy polyethylene glycol‐phosphate (mPEG‐P) is introduced as an electrolyte additive to achieve long anti‐calendar aging and high‐rate capabilities. The polyanionic of mPEG‐P self‐assembles via noncovalent‐interactions on electrode surface to form polyether‐based cation channels and in situ organic–inorganic hybrid solid electrolyte interface layer, which ensure rapid Zn2+ mass transfer and suppresses interfacial parasitic reactions, realizing outstanding cycling/calendar aging stability. As a result, the Zn//Zn symmetric cells with mPEG‐P present long lifespans over 9000 and 2500 cycles at ultrahigh current densities of 120 and 200 mA cm−2, respectively. Besides, the coulombic efficiency (CE) of the Zn//Cu cell with mPEG‐P additive (88.21%) is much higher than that of the cell (36.4%) at the initial cycle after the 15‐day calendar aging treatment, presenting excellent anti‐static corrosion performance. Furthermore, after 20‐day aging, the Zn//MnO2 cell exhibits a superior capacity retention of 89% compared with that of the cell without mPEG‐P (28%) after 150 cycles. This study provides a promising avenue for boosting the development of high efficiency and durable metallic zinc based stationary energy storage system.

Published: June 2024

AbstractINTRODUCTIONPrimary age‐related tauopathy (PART), often regarded as a minimally symptomatic pathology of old age, lacks comprehensive cohorts across various age groups.METHODSWe examined PART prevalence and clinicopathologic features in 1589 forensic autopsy cases (≥40 years old, mean age ± SD 70.2 ± 14.2 years).RESULTSPART cases meeting criteria for argyrophilic grain diseases (AGD) were AGD+PART (n = 181). The remaining PART cases (n = 719, 45.2%) were classified as comorbid conditions (PART‐C, n = 90) or no comorbid conditions (pure PART, n = 629). Compared to controls (n = 208), Alzheimer's disease (n = 133), and AGD+PART, PART prevalence peaked in the individuals in their 60s (65.5%) and declined in the 80s (21.5%). No significant clinical background differences were found (excluding controls). However, PART‐C in patients inclusive of age 80 had a higher suicide rate than pure PART (p < 0.05), and AGD+PART showed more dementia (p < 0.01) and suicide (p < 0.05) than pure PART.DISCUSSIONOur results advocate a reevaluation of the PART concept and its diagnostic criteria.Highlights
We investigated 1589 forensic autopsy cases to investigate the features of primary age‐related tauopathy (PART).
PART peaked in people in their 60s in our study.
Many PART cases over 80s had comorbid pathologies in addition to neurofibrillary tangles pathology.
Argyrophilic grain disease and Lewy pathology significantly affected dementia and suicide rates in PART.
Our results suggest that the diagnostic criteria of PART need to be reconsidered.

AbstractOver the past decades, accumulating evidence suggests that the gut microbiome exerts a key role in Alzheimer's disease (AD). The Alzheimer's Association Workgroup is updating the diagnostic criteria for AD, which changed the profiles and categorization of biomarkers from “AT(N)” to “ATNIVS.” Previously, most of studies focus on the correlation between the gut microbiome and amyloid beta deposition (“A”), the initial AD pathological feature triggering the “downstream” tauopathy and neurodegeneration. However, limited research investigated the interactions between the gut microbiome and other AD pathogenesis (“TNIVS”). In this review, we summarize current findings of the gut microbial characteristics in the whole spectrum of AD. Then, we describe the association of the gut microbiome with updated biomarker categories of AD pathogenesis. In addition, we outline the gut microbiome‐related therapeutic strategies for AD. Finally, we discuss current key issues of the gut microbiome research in the AD field and future research directions.Highlights

Published: June 2024

AbstractThe Wittig reaction is renowned as exceptionally versatile method for converting a diversity of aldehydes and ketones into alkenes. Recently, strategies for chiral phosphine catalysis under PIII/PV=O redox cycling emerged to render this venerable transformation stereoselective. Herein, we describe that phosphine redox catalysis enables the enantioselective synthesis of pertinent biaryl atropisomers by means of a stereocontrolled arene‐forming Wittig reaction. Key to the process is the release of an endogenous base from readily accessible tert‐butyloxycarbonylated Morita–Baylis–Hillman adducts triggered by catalyst intramolecularization, permitting mild phosphine redox catalysis for atroposelective Wittig reactions. By this strategy, a broad diversity of biaryl atropisomers is obtained with up to 94 : 6 enantioselectivity.

Published: July 2024

AbstractAntimicrobial resistance (AMR) poses a serious threat to human health worldwide. It is now more challenging than ever to introduce a potent antibiotic to the market considering rapid emergence of antimicrobial resistance, surpassing the rate of antibiotic drug discovery. Hence, new approaches need to be developed to accelerate the rate of drug discovery process and meet the demands for new antibiotics, while reducing the cost of their development. Machine learning holds immense promise of becoming a useful tool, especially since in the last two decades, exponential growth has occurred in computational power and biological big data analytics. Recent advancements in machine learning algorithms for drug discovery have provided significant clues for potential antibiotic classes. Apart from discovery of new scaffolds, the machine learning protocols will significantly impact prediction of AMR patterns and drug metabolism. In this review, we outline power of machine learning in antibiotic drug discovery, metabolic fate, and AMR prediction to support researchers engaged and interested in this field.
Predefined‐time adaptive neural dynamic surface tracking control for high‐order nonlinear switched systems
Authors: Meng Zhu , Ma Jiawei , Wang Huanqing 
Published: June 2024

AbstractIn this article, the issue of adaptive predefined‐time control for high‐order switched systems is researched. Neural networks (NNs) are introduced to approximate the uncertain nonlinear functions. In particular, a novel predefined‐time convergence filter is proposed to refrain from the problem of repeated differentiation of virtual controllers. On the basis of the backstepping recursion technique and the common Lyapunov function (CLF) approach, a neural adaptive predefined‐time dynamic surface control (DSC) scheme is proposed that can demonstrate all the signals in closed‐loop systems are bounded and the tracking error can converge to a small area near zero within predefined time. The simulation results illustrate the effectiveness of the proposed control scheme.

Published: June 2024

AbstractDie Europäische Weltraumbehörde (ESA) stellte kürzlich freie Forschungssatellitendaten zur Verfügung. Damit sind auch Erdoberflächenverformungen berührungslos mittels Radarinterferometrie aus dem Weltraum bestimmbar. Gleichzeitig werden sensorlos viele Punkte erfasst und Zeitreihen gebildet. Die erzielte Genauigkeit, im Zentimeterbereich, reicht zwar für Messungen von Erdbewegungen aus, aber noch nicht für Bauwerke. In diesem Beitrag wird ein neues Verfahren für ein Verformungsmonitoring am Beispiel der Schottwienbrücke in Österreich demonstriert. Verwendet werden sowohl historisch aufgezeichnete Satellitendaten sowie Messdaten aus künstlich am Bauwerk angebrachten „Corner‐Reflektoren“, welche mit Fernerkundungsmethoden ausgewertet werden. Ein entwickeltes Modell kann die Bauwerktemperatur auf Basis von Netzwetterdaten sensorlos prognostizieren und zur Genauigkeitssteigerung die thermischen Brückenverformungen kompensieren. Die Jahresmessungen von 2022 zeigen im Vergleich zum Referenzsystem (digitale Schlauchwaage) eine Standardabweichung von 1,7 bis 3,0 mm sowohl mit künstlichen Corner‐Reflektoren als auch bei natürlichen Rückstreupunkten ohne Sensoren am Bauwerk. Somit können mit Satelliten gleichzeitig viele Brücken im Intervall von 6 Tagen erfasst und auch retrospektiv bis ins Jahr 2016 zurück ausgewertet werden. Bedingt durch die zeitverzögerte Prozessierung eignet sich ein Satellitenmonitoring derzeit gut für die Langzeitverformungsüberwachung von weitgespannten Brücken.
