AbstractHafnium oxide (HfO2)‐based devices have been extensively evaluated for high‐speed and low‐power memory applications. Here, the influence of aluminum (Al) and lanthanum (La) co‐doping HfO2 thin films on the ferroelectric characteristics of hafnium‐based devices is investigated. Among devices with different La/Al ratios, the Al and La co‐doped hafnium oxide (HfAlAO) device with 4.2% Al and 2.17% La exhibited the excellent remanent polarization and thermostability. Meanwhile, first principal analyses verified that hafnium‐based thin films with 4.2% Al and 2.17% La promoted the formation of the o‐phase against the paraelectric phase, providing theoretical support for supporting experimental results. Furthermore, a vertical ferroelectric HfO2 memory based on 3D macaroni architecture is reported. The devices show excellent ferroelectric characteristics of 22 µC cm−2 under 4.5 MV cm−1 and minimal coercive field of ≈1.6 V. In addition, the devices exhibit great memory performance, including the response speed of device can achieve 20 ns and endurance characteristic can achieve 1010 cycles.

Published: December 2024

AbstractSecond‐order elastic topological insulators (SETIs) with tightly localized corner states present a promising avenue for manipulating elastic waves in lower dimensions. However, existing SETIs typically support corner states of only a single mode, either out‐of‐plane or in‐plane. In this work, an on‐chip SETI that simultaneously hosts both high‐frequency out‐of‐plane and in‐plane corner states at ≈0.2 MHz is introduced. The presence of these corner states is experimentally validated, and their selective excitation by tuning the excitation frequency is demonstrated. This capability to demultiplex out‐of‐plane and in‐plane corner states positions the SETI as a potential platform for developing multifunctional elastic devices and enhancing the communication capacities of elastic waves. Furthermore, due to its structural simplicity, the SETI can be readily scaled and integrated into on‐chip elastic circuits, making it suitable for applications in micro‐electromechanical systems.

AbstractLayered double hydroxides (LDHs) can serves as catalysts for CO2 photocatalytic reduction (CO2PR). However, the conventionally synthesized LDHs undergo undesired aggregation, which results in an insufficient number of active sites and limits the desirable electron transfer required for CO2PR. The metal‐organic framework (MOF) template‐grown LDHs demonstrate excellent promise for exploiting the strengths of both MOFs and LDHs. Herein, the in situ growth of MIL‐68(In)‐NH2 MOF‐templated Co–In bimetallic catalyst (CoIn‐LDH/MOF) having an ultrathin nanosheet morphology on the preserved rod‐like MOF template is demonstrated. Compared to the conventionally grown bimetallic LDH (CoIn‐LDH), CoIn‐LDH/MOF not only exposes more active sites but also possesses hydroxyl vacancies (VOH) and Co vacancies (VCo). Thus, CoIn‐LDH/MOF performs a higher CO generation rate of 2320 µmol g−1 h−1 during CO2PR, demonstrating improved activity and selectivity than those in CoIn‐LDH. Experiments coupled with calculations reveal that the CoIn‐LDH/MOF‐driven CO2PR follows the *COOH pathway. The lower energy barriers for the formation of *COOH and CO(g) can be attributed to the coexistence of VOH and VCo in CoIn‐LDH/MOF, effectively promoting charge transfer and enhancing CO2PR performance. This study provides a new strategy to obtain high‐performant LDH‐based catalysts with improved morphology.
The ZnO‐SiO2 Composite Phase with Dual Regulation Function Enables Uniform Zn2+ Flux and Fast Zinc Deposition Kinetics Toward Zinc Metal Batteries

Published: December 2024

AbstractAs an important candidate for rechargeable energy storage devices, the large‐scale development of aqueous zinc ion batteries has been hindered by hydrogen evolution and uncontrollable dendrites of metal anodes. A novel ZnO‐SiO2 composite interface phase (Zn@ZSCP) with a double protective effect based on in situ synthesis by hydrothermal method is used to improve these difficulties. The hydrophilic SiO2 layer is beneficial to the dissolution of hydrated zinc ions and reduces the nucleation barrier during zinc deposition, while the stable ZnO layer helps to adjust the electric field distribution on the surface of the metal anode to further induce uniform zinc nucleation. The cycle life of the Zn@ZSCP||Zn@ZSCP symmetric battery based on this innovative interface phase modification is up to 2500 h. Even at a high current density of 8 mA cm−2, the symmetric battery still has a stable cycle life of more than 2000 h. The zinc‐iodine full battery based on Zn@ZSCP anode and low‐cost biomass‐derived porous carbon exhibits an excellent specific capacity and outstanding cycle stability. This simple and reasonable battery structure design not only improves the practicability of aqueous zinc ion batteries to a certain extent but also helps to develop more efficient and environmentally friendly zinc metal batteries.

Published: December 2024

AbstractCircularly polarized luminescence (CPL) materials with rich optical information are highly attractive for optical display, information storage, and encryption. Although previous investigations have shown that external force fields can induce CPL activity in nonchiral systems, the unique role of macroscopic external forces in inducing CPL has not been demonstrated at the level of molecule or molecular aggregate. Here, a canonical example of CPL generation by mechanical twisting in an achiral system consisting of a polymer matrix with embedded fluorescent molecules is presented. By carefully adjusting the twisting parameters in time and space, in conjunction with circular dichroism (CD), CPL, and 2D wide‐angle X‐ray scattering (2D WAXS) studies, a twisting‐induced top‐down chiral transfer mechanism derived from the molecular‐level asymmetric rearrangement of fluorescent units is elucidated within polymers under external torsional forces. This top‐down chiral transfer provides a simple, scalable, and versatile mechanical twisting strategy for the fabrication of CPL materials, allowing for fabricating full‐color and handedness‐tunable CPL fibers, where the macroscopic twist direction determines the CPL handedness. Moreover, the weavability of CPL fibers greatly extend their applications in anti‐counterfeit encryption, as demonstrated by using embroidery techniques to design multilevel encryption patterns.

ABSTRACTObjectiveMilitary Police officers of Rio de Janeiro's State have been considered the most lethal security forces in Brazil, corresponding to 52.35% of deaths in policing actions. The main aim of this study was to identify occupational stress among military police officers in Rio de Janeiro State and its relationship with the psychosocial environment, sleep quality, and daytime sleepiness.MethodsTwo hundred and forty‐two military policemen, divided into two groups (elite and non‐elite), were evaluated occupational stress by the Lipp's Stress Symptoms Inventory (LSSI), daytime sleepiness (DS) by the Epworth Sleepiness Scale and sleep quality (SQ) by the Pitsburgh Sleep Quality Index.ResultsMilitary police officers (entire sample) showed dissatisfaction related to psychological support from the military institution (p = 0.004), about the inefficiency of the judicial system (p < 0.001) and their low popularity towards society (p = 0.009). The group of elite police officers slept significantly less (p = 0.026) and, in general, suffered more from severe daytime sleepiness, had poorer SQ and showed lower levels of occupational stress than their peers. It was possible to identify that stress can be detected, developed, and intensified in military police officers as a result of the environment in which they are exposed and this interferes significantly in sleep and daytime sleepiness (p < 0.05).ConclusionThrough this study, it is hoped that measures can be implemented to enhance the work environment and thereby improve the quality of life for this military population. Furthermore, it is intended to stimulate more comprehensive and longitudinal studies, particularly inclusive of female military personnel.

ABSTRACTTurner‐type X‐linked syndromic intellectual developmental disorder (MRXST) is a neurodevelopmental disorder associated with variants in the HUWE1 gene on chromosome Xp11. The condition is characterized by variable phenotypes, including global developmental delay, intellectual disability, and distinctive facial dysmorphisms, with inheritance patterns ranging from X‐linked recessive to de novo mutations in females. Here, we describe five probands in two families, highlighting their clinical features and genetic findings. Trio whole‐exome sequencing identified a de novo variant in HUWE1 in the proband in one family and a maternally inherited hemizygous variant in three boys in a second family. A comprehensive review of HUWE1‐associated cases from the literature assisted genotype–phenotype correlations, revealing consistent features such as intellectual disability, skeletal anomalies, and facial dysmorphisms as well as instances of intrafamilial variability. Our findings confirm the phenotypic variability of MRXST and underscore the significance of the HUWE1 gene product in neurodevelopment. We propose a baseline monitoring protocol to aid in diagnosis and management, contributing to the development of specific guidelines for patient follow‐up.

AbstractPurification and storage of acetylene (C2H2) are important to many industrial processes. The exploitation of metal–organic framework (MOF) materials to address the balance between selectivity for C2H2 vs carbon dioxide (CO2) against maximising uptake of C2H2 has attracted much interest. Herein, we report that the synergy between unsaturated Cu(II) sites and functional groups, fluoro (−F), methyl (−CH3), nitro (−NO2) in a series of isostructural MOF materials MFM‐190(R) that show exceptional adsorption and selectivity of C2H2. At 298 K, MFM‐190(NO2) exhibits an C2H2 uptake of 216 cm3 g−1 (320 cm3 g−1 at 273 K) at 1.0 bar and a high selectivity for C2H2/CO2 (up to ~150 for v/v = 2/1) relevant to that in the industrial cracking stream. Dynamic breakthrough studies validate and confirm the excellent separation of C2H2/CO2 by MFM‐190(NO2) under ambient conditions. In situ neutron powder diffraction reveals the cooperative binding, packing and selectivity of C2H2 by unsaturated Cu(II) sites and free −NO2 groups.

Published: December 2024

ABSTRACTSodium 4‐styrene sulfonate was polymerized with lignosulfonic acid (LS) to obtain adsorbents for copper ions. The percentage of LS was varied, and the obtained systems were characterized by Fourier‐transformed infrared spectroscopy, thermogravimetry, and scanning electron microscopy. Chemical composition, adequate thermostability, and a porous morphology with a pore size distribution favoring Cu(II) adsorption were corroborated. In hydration studies, all systems have a swelling capacity higher than 2000% at 60.0 min, whereas systems prepared with 20.0 and 30.0 wt.% of LS adsorb a higher amount of water owing to the high availability of polar sites. In contrast, adsorption studies were able to capture 25.1 mg of Cu(II) per g of adsorbent (prepared with 30.0 wt.% LS). The data obtained were fitted to a pseudo‐first‐order kinetics and Freundlich isotherm model, indicating a heterogeneous adsorbent surface. The thermodynamic parameters demonstrated the affinity between the active sites of the solid and Cu(II) in solution. It was determined that the adsorption mechanism is governed by the concentration gradient of Cu(II) at the interface (adsorbent–solution) and interactions of ion exchange and complexation types. Finally, the reuse of the bio‐based adsorbent was achieved in consecutive adsorption–desorption cycles in up to four cycles.

Published: December 2024

ABSTRACTThis work aims to experimentally investigate the elaborated nanocomposite based on the MEH‐PPV‐P3HT copolymer as a donor, which blended with the SWCNTs as an acceptor with different weight concentrations (1%, 3%, and 5% of SWCNTs). Various characterization techniques have been performed to analyze the effect of varying the SWCNTs' weight and the interaction between the two materials. The morphological and vibrational analysis were carried out using transmission electron microscopy (TEM) and Raman's spectroscopy, which indicate the dispersion of the SWCNT in the copolymer matrix. To analyze the optical properties, UV–visible, photoluminescence, and time‐resolved photoluminescence techniques have been used. To ascertain the influence of the SWCNTs addition, a comparative study between the resulting nanocomposite, basic copolymer, and various SWCNT concentrations has been examined. The results that have been accomplished demonstrate that the mixing between the copolymer MEH‐PPV‐P3HT and the SWCNTs reduces the band gap energy to be equal to 1.7 eV enhancing the charge transfer (CT) process and increases the absorption volume in the visible range. An increment in the average decay time compared to the MEH‐PPV‐P3HT has been noticed which improves the non‐radiative luminescence process. To analyze the intermolecular interaction, theoretical modeling using density functional theory (DFT) has been performed.

ABSTRACTA high strength bonding interface by resistance welding has always been a goal for the production of highly reliable resin‐based composite joints. In this work, SS mesh element with grafted ZnO nanowires (SSM@ZnO) was developed for resistance welding of CF/PEEK composite laminates to improving interfacial strength. First, the surface of stainless‐steel mesh (SSM) was modified by in Situ grafting of zinc oxide (ZnO) nanowires via hydrothermal growth method and the as‐obtained product (SSM@ZnO) used to the resistance welding of carbon fiber/polyether ether ketone (CF/PEEK) orthogonal laminates. The dependance of the SSM@ZnO microstructure, heating properties, wettability and interfacial adhesion on the growth time was investigated. The electrical heating rate under constant input power is increased from 4.8°C/s to 7.12°C/s, and IFSS between SSM@ZnO and PEEK resin is increased from original 45 MPa to 61 MPa. The mechanical properties and failure mode of CF/PEEK resistance welding joints were characterized by single lap shear stress (SLSS) and SEM, respectively. At SSM@ZnO growth time of 8 h, the SLSS reaches the maximum value of 52.8 MPa, and the failure mode was shifted from interfacial peeling between CF/PEEK laminate and adhesion layer to fiber tearing of CF/PEEK laminate surface.

ABSTRACTGlucose‐regulated protein 78 (Grp78), a crucial molecular chaperone in the endoplasmic reticulum, has been extensively investigated in vertebrates. However, its functional exploration in insects remains limited. This study cloned the full‐length cDNA sequence of Grp78 in Plutella xylostella (L.), which is 2583 bp long. The open reading frame (ORF) is 2004 bp in length and encodes a total of 667 amino acids, including three conserved characteristic sequences of the HSP70 family. PxGrp78 is expressed in various developmental stages of P. xylostella, with the highest expression observed in third instar larvae and higher expression in female adults compared to male adults. The interference with PxGrp78 in female adults was found to significantly reduce the quantity of egg laying and the hatching rate, as well as shorten the oviposition period and down‐regulate the expression of the PxVg gene. These results suggested an important role for PxGrp78 in the reproduction of P. xylostella.

AbstractNitric oxide is an important signalling molecule responsible for maintaining body's homeostasis. Any dysregulation in NO can lead to many pathological conditions like atherosclerosis, cancers, neurodegenerative disorders, hypertension and inflammation. Several, sensing technologies are used for sensing NO. Among these, fluorescent imaging is considered to be one of the most efficient. Till date, approximately 123 fluorescent probes are reported related to nitric oxide (NO) sensing fluorescent probes for the sensitive, selective, and real‐time detection of NO at both the cellular and subcellular levels. In the past five years, around 41 fluorescent probes and four review articles have been published, specifically focusing on the detection of nitric oxide. Despite considerable advancements in this area, no systematic review has summarized various organelle‐targeting NO‐sensing fluorescent probes. Herein, we summarized last five years from 2019 to 2024 along with the key pioneering research in this field covering divergent roles of NO across various cellular organelles. We have included 41 probes by classifying into different organelle targeting sections. We strongly believe this review will provide an advanced summary of NO specific fluorescent probes and their applications for monitoring the progression of diseases in in vitro to in vivo models such as drosophila, zebrafish, mouse models.

AbstractIn inclusive preschools, children with autism spectrum disorder (ASD) and other developmental disabilities (DD) are less socially engaged with peers than are typically developing (TD) children. However, there is limited objective information describing how children with ASD engage with teachers, or how teacher engagement compares to engagement with peers. We tracked over 750 hours' worth of children's (N = 77; NASD = 24, NDD = 23, NTD = 30; Mage = 43.98 months) and teachers' (N = 12) locations and orientations across eight inclusion preschool classrooms to quantify child‐teacher and child‐peer social preference. Social approach velocity and time in social contact were computed for each child and compared across social partners to index children's preference for teachers over peers. Children with ASD approached teachers–‐but not peers—more quickly than children with TD, and children with ASD were approached more quickly by teachers and more slowly by peers than children with TD. Children with ASD spent less time in social contact with peers and did not differ from children with TD in their time in social contact with teachers. Overall, children with ASD showed a greater preference for approaching, being approached by, and being in social contact with teachers (relative to peers) than children with TD. No significant differences emerged between children with DD and children with TD. In conclusion, children with ASD exhibited a stronger preference for engaging with teachers over peers, re‐emphasizing the need for classroom‐based interventions that support the peer interactions of children with ASD.

ABSTRACTEthoxysanguinarine (ETSG), a benzophenanthridine alkaloid, exhibits diverse biological activities, including antibacterial, antifungal, anti‐inflammatory, antioxidant, and anti‐tumor effects. Despite these properties, limited research exists on ETSG in vivo pharmacokinetics due to its poor solubility and low bioavailability. In this study, we developed a rapid and specific UPLC‐MS/MS method for ETSG bioanalysis. Sample preparation involved one‐step protein precipitation using methanol and phellodendrine as an internal standard (IS). The Waters HSS T3 column (2.1 * 50 mm, 1.8 μM) employed a gradient elution with mobile phases A (2 mmol/L ammonium formate aqueous solution‐formic acid [99.8:0.2, v/v]) and B (methanol‐formic acid [99.8:0.2, v/v]). Mass analysis via Waters Q‐mass spectrometer utilized positive scan mode and multiple reaction monitoring. ETSG and IS were detected at m/z 332.0 → 274.0 and 342.0 → 177.0, respectively, within 7.0 min. The method demonstrated excellent precision, accuracy, recovery, and stability, with a linear calibration curve (1.1–560 ng/mL) and strong correlation coefficient (0.9984). Successful pharmacokinetic evaluation in Sprague–Dawley rats included intravenous ETSG administration and intragastric ETSG nanoemulsion/suspension. This method enables steroidal saponin analysis from ETSG in biological samples.
