Aim: The present study was conducted to investigate the preventive/curative effect of aqueous seed extract Syzygium aromaticum in alloxan-induced diabetes in rats.
Study Design: Twenty Wistar rats were randomly divided into four groups. The ﬁrst group served as a control (received 1 ml of normal saline). The second group served as Diabetic control (received 1 ml of normal saline). The third group served as test 1 (pre-treated with 500 mg/kg body weight (b.w.) of aqueous Syzygium aromaticum seeds extract for seven days prior to diabetic induction and post-treated with aqueous seeds extract of Syzygium aromaticum after diabetic induction) and the fourth group served as test 2 (post-treated with 500 mg/kg b.w. of aqueous seed extract of Syzygium aromaticum after diabetic induction) in a daily oral dose for 14 days.
Results: Treatment of rats with aqueous seed extract of Syzygium aromaticum in a daily dose of 500 mg/kg significantly mitigates the induced changes in the glucose and lipid proﬁle parameters. Histopathological examination of the pancreas showed the destruction of β-cells in the diabetic control group and recovery of damaged tissues when treated with 500 mg/kg b.w. of aqueous seeds extract of Syzygium aromaticum.
Conclusion: The present study suggests that aqueous seed extract S. aromaticum seeds extract at a dose of 500 mg/kg body weight brings about regeneration of the B-cells of the pancreas and signiﬁcant beneﬁcial effects in various physiological parameters in alloxan-induced diabetes.

AbstractThis study investigated a biomimetic co‐assembly design strategy inspired by morning glory vines to create a stable wearable platform. MXene exhibits a remarkably high electrical conductivity, which is advantageous in heating applications. However, its susceptibility to oxidation gives it low stability in air, which limits its application potential. Conventional heaters degrade as a result of mechanical stress and environmental factors such as humidity and high temperatures. To address these challenges, a surface‐modified MXene fiber that is twisted with a supporting thread is developed, then coated with an insulating polymer. This twisting process is inspired by the ability of a vine to wrap around supports. It enhances the mechanical stability by distributing forces like bending, twisting, and stretching. The resulting MXene heating wire (MXHW) shows an increase in mechanical durability (with elongations of up to 17.5%) before twisting (1%). It remained stable under a 22.5 N load. Furthermore, the MXHW and a woven MXene heating fabric (MXHF) shows stable performances over 48 h under humidity of 99% and temperature of 80 °C. They retained their stability after 12 000 bending cycles. These observations emphasized the potential of the MXHF in wearable technologies to provide a durable solution adaptable to various environments.

AbstractIt is known that large‐scale synthesis of emitters affords colloidal quantum dot (CQD) materials with a great opportunity toward the mass production of quantum dot light‐emitting diodes (QLEDs) based commercial electronic products. Herein, an unprecedented example of scalable CQD (> 0.5 kilogram) is achieved by using a core/shell structure of CdZnSe/ZnSeS/CdZnS, in which CdZnSe, ZnSeS, and CdZnS alloys are used as the inner core, transition layer and outermost shell, respectively. It exhibits a high fluorescence quantum yield (>90%), a robust excited state, and a fast radiative transition rate. The investigation of morphology and surface state reveals the possible reasons for such excellent optical properties, which include uniform size distribution, no undesired byproducts, and high defect tolerance. The QLEDs exhibit a peak external quantum efficiency of over 21%, a high luminance of over 9.5×104 cd m−2, and a long lifetime of over 1.0×106 h, corresponding to the state‐of‐the‐art performance among the QLEDs based on the large‐scale synthesis of CQDs. Therefore, it is believed that an efficient and reliable strategy is provided toward the large‐scale synthesis of CQDs, which can be used as emitters in the QLEDs‐based commercial electronic devices and make the mass production of these products a reality.

AbstractTin‐based perovskites are more environmentally friendly than their lead‐based alternatives. Perovskite light‐emitting diodes (PeLEDs) using iodide‐based tin perovskites have achieved considerable advancements in efficiency. However, PeLEDs using bromide‐based tin perovskites have not progressed as rapidly, primarily due to challenges in controlling their crystallization processes. Here, an interfacial reaction‐assisted crystallization method is introduced to achieve bright and efficient CsSnBr3 PeLEDs. It is started by forming an intermediate phase through the coordination of SnBr2 with ethylenediamine derivatives. Subsequently, a protonation reaction is designed between the intermediate phase and the acidic polyethylenedioxythiophene: poly(styrene sulfonate) hole‐transport layer to generate high‐quality CsSnBr3 films. Additionally, the use of potassium thiocyanate additives effectively enhances the photoluminescence efficiency of the CsSnBr3 films. These efforts result in CsSnBr3‐based PeLEDs achieving a maximum luminance of 787 cd m−2 and a peak external quantum efficiency of 0.91%, demonstrating the most efficient and brightest CsSnBr3‐based PeLEDs to date. This work opens an avenue to better control the crystallization of tin‐based perovskite.

AbstractLaser‐driven projection displays face a critical challenge in developing laser‐excitable and high‐performance narrowband green emitters. Herein, new Al2O3‐LaMgAl11O19: Mn2+ (Al2O3‐LMA: Mn2+) transparent composite ceramics are reported via high‐temperature vacuum sintering, which produces a high‐color‐purity (95.4%) green emission with full width at half maximum of 24 nm and superior thermal and moisture and laser irradiation stability. These are attributed to low electron‐phonon couple, weak crystal‐field effect, an individual lattice location of Mn2+ activators in high structural rigid host, and the incorporation of a high‐thermal‐conductivity Al2O3 secondary phase. As a result, the composite ceramics are demonstrated as an attractive color converter with a high external quantum efficiency (38%) and absorption coefficient (53%), which ensures a luminous flux of 2012 lm @40.0 W, a luminous efficacy of 67.7 lm W−1, and a green light conversion efficiency of 20.3% upon blue laser irradiation. This enables to construct a brand‐new laser‐driven prototype display with a record color gamut beyond Rec.2020 standard (100.8%), outperforming commercial YAG: Ce3+ and β‐SiAlON: Eu2+. This exploration in ultra‐narrowband green luminescent materials is poised to accelerate the development of “ideal displays” for laser‐driven projection display technology.

AbstractSilicon is a promising negative electrode material for solid‐state batteries (SSBs) due to its high specific capacity and ability to prevent lithium dendrite formation. However, SSBs with silicon electrodes currently suffer from poor cycling stability, despite chemical engineering efforts. This study investigates the cycling failure mechanism of composite Si/Li6PS5Cl electrodes by decoupling the effects of interface chemical degradation and mechanical cracking. Chlorine‐rich Li5.5PS4.5Cl1.5 suppresses interface chemical degradation when paired with silicon, while small‐grained Li6PS5Cl shows 4.3‐fold increase of interface resistance due to large Si/Li6PS5Cl contact area for interface degradation. Despite this, small‐grained Li6PS5Cl improves the microstructure homogeneity of the electrode composites, effectively alleviating the stress accumulation caused by the expansion/shrinkage of silicon particles. This minimizes bulk cracks in Li6PS5Cl during the lithiation processes and interface delamination during the delithiation processes. Mechanical cracking shows a dominant role in increasing interface resistance than interface chemical degradation. Therefore, electrodes with small‐grained Li6PS5Cl show better cycling stability than those with Li5.5PS4.5Cl1.5. This work not only provides an approach to decouple the complex effects for cycling failure analysis but also provides a guideline for better use of silicon in negative electrodes of SSBs.

AbstractSemiconducting single‐wall carbon nanotubes (s‐SWCNTs) represent one of the most promising materials for surpassing Moore's Law and developing the next generation of electronic devices. Despite numerous developed approaches, reducing the contact resistance of s‐SWCNTs networks remains a significant challenge in achieving further enhancements in electronic performance. In this study, antimony triiodide (SbI3) is efficiently encapsulated within high‐purity s‐SWCNTs films at low temperatures, forming 1D SbI3@s‐SWCNTs vdW heterostructures. The semiconductor–metal transition of individual SbI3@s‐SWCNTs is characterized via sensitive dielectric force microscopy, with the results confirmed through electrical device tests. The electrical behavior transition is attributed to an interlayer charge transfer, as demonstrated by Kelvin probe force microscopy. Moreover, the electrical performance of s‐SWCNTs thin‐film transistors improves significantly with SbI3@s‐SWCNTs networks as contact electrodes. This process reduces the contact resistance between the s‐SWCNTs channel and the electrodes, enhancing electrical performance. Specifically, the contact resistance decreases to one‐third of the original, the carrier mobility increases by ≈10 times, the on‐off ratio exceeds 106, and the subthreshold swing reduces significantly to ≈65 mV dec−1. These results demonstrate the effectiveness of inner‐doping‐induced metallization of s‐SWCNTs in the contact region, essential for advancing carbon nanotube electronic devices and circuits.

AbstractNowadays, metasurfaces have attracted considerable attention due to their promising and advanced control of electromagnetic (EM) waves. However, it is still challenging to shape guided waves into desired free‐space mode, while simultaneously manipulating spatial incident waves using a single metasurface. Herein, a class of metasurfaces capable of multiplexing guided and space waves is proposed to achieve advanced EM functionalities in microwave regions, which can find great application potentials in radar systems, wireless communications, and wireless power transfer (WPT). The proposed metasurface, composed of specially designed meta‐atoms with polarization‐dependent radiation and reflection properties, provides the capability to fully manipulate complex amplitude of guided waves and reflection phase of space incident wave independently and simultaneously, thus enabling arbitrary radiation and reflection functionalities without encountering crosstalk issues. As examples of potential applications, three advanced EM functionalities operating in both far‐field and near‐field regions are presented: low‐sidelobe microwave antenna with reduced radar cross section (RCS), multifunctional WPT, and feed multiplexed holograms, respectively. The far‐field characteristics of the low sidelobe level antennas showing radiated beams at ± 30° together with RCS reduction under arbitrarily polarized incidences are validated by both simulations and measurements. A good agreement between experiments and simulations is also observed for the near‐field intensity distribution of the hologram, which further validates the feasibility of near‐field shaping. The findings significantly expand the capabilities of metasurfaces in manipulating EM waves and stimulate advanced multifunctional metadevices facing more challenging and diversified application demands.

Published: December 2024

AbstractThe treatment of contaminants in water has become one of the most critical environmental issues today, especially oil‐ and dye‐pollutants in water, for which there is still no efficient and economical solution. A multifunctional phase‐selective organogel (tert‐butyl (S)‐(5‐amino‐1,5‐dioxo‐1‐(tetradecylamino)pentan‐2‐yl)carbamate, TBTC) is developed to remove oils and dyes from water. Benefiting from the significant van der Waals interaction between the long alkyl chain of TBTC and the oil, TBTC can rapidly disperse into the oil phase. Then, TBTC aggregates into fibers and solidifies oil through a repairable, dynamic, and balanced hydrogen bonding network, which can solidify and recover the spilled oil at room temperature. TBTC can also efficiently remove more than a dozen typical dye contaminants through a host–guest recognition mode. The mechanism of host–guest recognition is studied by experiment combined with multiscale calculations. Partial 1H VT NMR, FTIR, and XRD experiments have shown that the main driving force for TBTC gelation and host–guest recognition originates from interaction hydrogen bonding, are TBTC specifically recognizes dye molecules through weak hydrogen bonding interactions and rapidly aggregates to form precipitates. TBTC‐based organogel provides a potential solution for oil spill recovery and removal of dyes from water.

Published: December 2024

AbstractBallast water, which is seawater taken onboard ships to ensure stable and maneuverable sailing, can pose a significant threat to marine ecosystems and human health when discharged owing to the presence of undesirable organisms. To mitigate this risk, ballast water treatment methods such as electrochlorination are employed, where oxidants such as hypochlorite are generated to effectively eliminate marine microorganisms. The effectiveness of an electrochlorination‐based ballast water management system (BWMS) depends on the maintenance of optimal concentrations of total residual chlorine (TRC). However, excessive levels of free chlorine (Cl) can result in corrosion and environmental damage, rendering the accurate monitoring of TRC levels crucial for the safe discharge of ballast water. This review focuses on recent advancements in electrochemical sensors for free Cl measurement in BWMS. The process of free Cl generation, techniques for electrochemical detection, and factors influencing sensor performance are elucidated. In addition, materials and strategies for improving the performance of the sensors are described. Finally, perspectives on the current issues and future challenges that must be overcome to effectively utilize electrochemical detection in BWMS are discussed, thereby offering new directions for advancing this technology.

Published: December 2024

AbstractThis study investigates the impact of spatial confinement and the Hellmann potential on the Shannon entropy of a hydrogenic atom. A hydrogenic atom screened by the Hellmann potential and confined within an impenetrable spherical potential is analyzed. The Schrödinger equation is solved numerically using the finite difference method to determine energy eigenvalues and wavefunctions. These wavefunctions are examined in both position and momentum spaces to calculate the Shannon entropy in position space , the Shannon entropy in momentum space , and the total Shannon entropy . How the confinement radius and the screening parameter affect these entropies is investigated, and the results are compared to those of unconstrained systems. The findings are contrasted with previously reported results and discussed in relation to the Beckner–Bialynicki–Birula–Mycielski (BBM) inequality, offering insights into the behavior of quantum states under confinement. Significant variations in Shannon entropy and energy levels are observed with changes in confinement and screening parameters, providing a deeper understanding of quantum mechanics in confined systems. The study reveals a critical screening parameter at which the behavior of entropy transitions, shedding light on the interplay between spatial confinement, screening effects, and quantum uncertainties.

AbstractThe development of primary liver cancer (hepatocellular carcinoma [HCC] and intrahepatic cholangiocarcinoma [ICC]) is linked to its physical microenvironment, particularly extracellular matrix (ECM) stiffness. Potential anticancer strategies targeting ECM stiffness include prevention/reversal of the stiffening process and disruption of the response of cancer cells to mechanical signals from ECM. However, each strategy has limitations. Therefore, the authors propose integrating them to maximize their strengths. Compared with HCC, ICC has a stiffer ECM and a worse prognosis. Therefore, ICC is selected to investigate mechanisms underlying the influence of ECM stiffness on cancer progression and application of the integrated anticancer strategy targeting ECM stiffness. In summary, immunofluorescence results for 181 primary liver cancer tissue chips (ICC, n = 91; HCC, n = 90) and analysis of TCGA mRNA‐sequencing demonstrate that ECM stiffness can affect phenotypes of primary liver cancers. The YAP1/ABHD11‐AS1/STAU2/ZYX/p‐YAP1 pathway is a useful entry point for exploration of specific mechanisms of mechanical signal conduction from the ECM in ICC cells and their impact on cancer progression. Moreover, a synergistic anticancer strategy targeting ECM stiffness (ICCM@NPs + siABHD11‐AS1@BAPN) is constructed by integrating ECM softening and blocking intracellular mechanical signal transduction in ICC and can provide insights for the treatment of cancers characterized by stiff ECM.

AbstractObserving chemical reactions in complex structures such as zeolites involves a major challenge in precisely capturing single‐molecule behavior at ultra‐high spatial resolutions. To address this, a sophisticated deep learning framework tailored has been developed for integrated Differential Phase Contrast Scanning Transmission Electron Microscopy (iDPC‐STEM) imaging under low‐dose conditions. The framework utilizes a denoising super‐resolution model (Denoising Inference Variational Autoencoder Super‐Resolution (DIVAESR)) to effectively mitigate shot noise and thereby obtain substantially clearer atomic‐resolved iDPC‐STEM images. It supports advanced single‐molecule detection and analysis, such as conformation matching and elemental clustering, by incorporating object detection and Density Functional Theory (DFT) configurational matching for precise molecular analysis. the model's performance is demonstrated with a significant improvement in standard image quality evaluation metrics including Peak Signal‐to‐Noise Ratio (PSNR) and Structural Similarity Index Measure (SSIM). The test conducted using synthetic datasets shows its robustness and extended applicability to real iDPC‐STEM images, highlighting its potential in elucidating dynamic behaviors of single molecules in real space. This study lays a critical groundwork for the advancement of deep learning applications within electron microscopy, particularly in unraveling chemical dynamics through precise material characterization and analysis.

Published: December 2024

AbstractMagnesium hydride (MgH2) is a promising hydrogen storage material for its high hydrogen capacity of 7.6 wt.%. However, the further application is severely hampered by the sluggish reaction kinetics and stable thermodynamics. Introducing catalysts is an effective method to improve the reaction rate, but the catalytic activity tends to decrease with an increasing number of reaction cycles, due to the highly reductive Mg and H species. Herein, the spring effect has been observed in the P doped Li3VO4, in which both V─P and V─V bonds undergo compression and elongation during hydrogen absorption and desorption, respectively. Such a unique self‐regulation spring effect not only improves the reaction kinetics of MgH2, but also maintains the high activity of P doped Li3VO4, thereby ensuring the hydrogen capacity of MgH2 even after 100 loops. This spring effect of chemical bonding, stretched‐recovered‐stretched with the motion between the highly reductive Mg and H species, will provide insight into catalyst design for hydrogen‐related industries.
