Published: October 2024

AbstractHybrid metal halides (HMHs) with time‐resolved luminescence behavior promise to be a breakthrough in multi‐level anti‐counterfeiting, but controlling the dynamic switching between phosphorescence and fluorescence is extremely challenging. Herein, an array of 0D HMHs is constructed by screening the π‐conjugated ligand with room‐temperature phosphorescence (RTP). Compared to the organic chromophore, (ETPP)2ZrCl6 possesses a misaligned stacking and rigid structure, contributing to an improved phosphorescence quantum yield (ΦP = 27.50%) and an extended phosphorescence lifetime (τ = 0.6234 s), as the intervening of inorganic unit [ZrCl6]2− suppresses the energy losses caused by nonradiative relaxation and prompts the intersystem crossover (ISC) process. Not only that, the interplay of phosphorescence‐fluorescence dual‐mode emission can be intelligently controlled by doping the active metal Te4+, resulting in a dynamic switching between RTP phosphorescence and self‐trapped exciton (STE) fluorescence. DFT calculations reveal the governing origins of RTP‐STE from the intermolecular ISC channels and spin‐orbit coupling (SOC) coefficients. These precise images into periodic pixelated arrays enable the multi‐level anti‐counterfeiting and information encryption. This work proposes a fluorescence‐phosphorescence co‐modulating strategy under the premise of dissecting the structural origins for optimizing RTP phosphorescence, which paves the way for designing high‐security‐level anti‐counterfeiting materials.

AbstractReconfigurable soft robots exhibit superior flexibility and adaptability when coping with complex environments and variable tasks. However, conventional modular design strategy based on soft actuator modules with specific structure and actuation mode as the basic constructing element for reconfigurable soft robots always has limited reprogrammability or scalability. Here, a hierarchical reconfigurable strategy is reported that not only offers conventional module reconfiguration as the first level to build different robot prototypes, but also provides the elastically‐guided multimodal actuation (contraction, bend, and twist) as the second level which can be reprogrammed to construct different actuator modules. This strategy deepens the modularity to a higher dimensionality and provides more choices for robots to adjust various conformations and functions as needed, for example, a peristalsis robot, an omnidirectional crawling robot, and a soft manipulator can be easily constructed using the module‐level reconfiguration. Moreover, soft manipulators with various preprogrammed deformation trajectories based on the mode reconfiguration are proven to dramatically reduce the operation difficulty and cost in potential applications such as environment detection and human‐robot interaction. This work provides a hierarchical framework for reconfigurable soft robots and may open up a new way for modular design.

AbstractSoft actuators that mimic the softness and deformability of living organisms have great potential for use in various fields. For most soft actuators, achieving both reprogrammable shape and high work capacity is crucial but challenging. These properties are mutually exclusive for liquid crystal elastomers (LCEs), an important type of soft actuators. Herein, a room‐temperature shape‐programmable LCE capable of high‐energy actuation is developed. Our approach utilizes hydrogen bonds to stabilize the aligned liquid crystal phases. The slow recovery of H‐bonds at room temperature provides a specific processing window, during which the sample shape can be programmed after the thermal treatment. The temperature‐dependent rearrangement of hydrogen bonds allows for fabrication of actuators with customized shapes in a facile do‐it‐yourself manner. Additionally, the integration of strong covalent cross‐links is vital for holding structural integrity. The combination of non‐covalent and covalent cross‐linking significantly improves the mechanical properties, enabling the actuators to perform reversible actuation with a work capacity (440 kJ m−3) higher than that of traditional LCEs (<100 kJ m−3). This study provides a turnkey strategy to address the conflict between shape reprogrammability and work capacity, advancing the development of soft actuators.

Published: October 2024

AbstractAqueous zinc‐selenium (Zn‐Se) batteries have garnered much attention due to their inherent safety and high specific capacity. Unfortunately, the problem of sluggish redox reaction represents a significant obstacle to the development of aqueous Zn‐Se batteries. Here, a nitrogen‐phosphorus asymmetrically coordinated copper single atom catalytic host material (CuN3P1@C) is synthesized for an aqueous Zn‐Se battery. The CuN3P1@C host material exhibits a rich porous structure, high‐loading of Cu single atoms, and unique asymmetric coordination environment, which significantly reduces the reaction energy barrier for the redox reaction between Se and Zn, enhancing the electrochemical performance of the aqueous Zn‐Se battery. Consequently, the Se/CuN3P1@C cathode achieves a high specific capacity of 756 mAh g−1 at 0.2 A g−1 and cycling stability of 4 000 cycles at 5.0 A g−1 (capacity decay of 0.0044% per cycle). Meanwhile, the conversion mechanism of an aqueous Zn‐Se battery is systematically explored via systematical characteristics and density functional theory calculations. This work opens up a novel approach to boosting the redox reaction of aqueous Zn‐Se batteries by modulating single atom‐based host materials via heteroatoms.

AbstractTwo‐dimensional perovskites containing an organic fluorophore can be a unique emitter for light‐emitting diodes (LEDs). However, external quantum efficiencies (EQEs) of fluorophore‐containing perovskite LEDs reported thus far are still very low. In this study, these are able to boost the EQE to ≈10% by choosing an organic fluorophore with appropriate energy levels for the perovskite structure organization. In the fluorophore‐containing perovskite LEDs, carrier transport and exciton formation take place in the perovskite's metal halide framework, thereby avoiding the direct formation of nonradiative triplet excitons on the organic fluorophores. Subsequently, the bright triplet excitons formed in the metal halide framework are transferred to form the radiative singlet states of the organic fluorophores, leading to efficient electroluminescence (EL) from the organic fluorophores regularly dispersed inside the perovskite structure. Unexpectedly higher light‐outcoupling efficiency, which is caused by the light scattering in the polycrystalline perovskite layer, will be another reason for efficient EL. These findings will contribute toward the fabrication of LED‐based products with high performance at a low cost.

AbstractMethodological improvement to single‐cell manipulation is critical for exploring the fundamentals of cellular life and unraveling biological complexity. Although micro‐manipulation technologies capable of precise cell localization have been widely established, scaling existing platforms for highly efficient single‐cell immobilization without sacrificing cell viability and sample quantity has proven challenging. Here, a highly efficient single‐cell trapping and arraying approach is introduced by advancing the performance of a microfluidic mechanical trapping chip. The chip can achieve representative single‐cell capture with over 99% efficiency and at least a 75% success rate of perfect capture, a precisely controlled single‐cell array, absolute sequential cell captures without cell loss, and the maintenance of high cell viability during the whole manipulation process. This approach enables diverse single‐cell trapping, large‐scale arraying manipulations, and dynamic cellular and molecular analysis, and offers a path toward the development of high‐performance single‐cell systems.

Published: October 2024

AbstractIn the present manuscript, the effect of vacancy and Stone‐Wales defects (SWD) on the structural and electronic properties of zigzag GaN nanoribbons (ZGaNNR) is investigated. Apart from the conventional SWD ( rotation of formula unit), the rotation of formula unit i.e., Ga–N by and is also considered, which revealed remarkable findings. It is observed that the incorporation of considered defects is an exothermic process and the proposed structures are energetically feasible to be obtained. The considered vacancy defects settled in a magnetic ground state while the SWD always prefer a non‐magnetic state. The observed magnetic state is always stable by more than 400 meV compared to the corresponding non‐magnetic state. Furthermore, N‐vacancy defect is energetically preferred over Ga‐vacancy as well as the SWD. The electronic properties of ZGaNNR are highly influenced by the incorporation of vacancy or SWD. A semiconductor to metallic transition for vacancy defects whereas reduction in the bandgap has been witnessed for SWD. A direct to indirect conversion as well as spin polarization was also noticed in the selected geometries. The findings indicate that apart from tailoring the electronic properties, these defects can also be used for the realization of magnetic semiconductors for potential spintronic applications.

Published: October 2024

AbstractAnalytical expressions for pair and higher‐order mutual information measures in position and momentum space are examined for many‐particle () coupled oscillator systems in their ground states. These relations reveal that the magnitudes of the statistical correlations monotonically increase with the strength of the particle interaction for all particle numbers (). On the other hand, the magnitudes of the measures monotonically decrease as increases, when the intensities of the one‐ and two‐body potentials are fixed. However, extremal points appear in the measures as is varied, when the intensity of the one‐body potential is ‐dependent, and set at . Fractional values of lead to the appearance of extremal points. These results illustrate how the intensity of the one‐body potential can be used to tune the behavior of the statistical correlation measures in these systems.

Published: October 2024

AbstractThe demand for multinarrowband absorber has attracted increasing interest among researchers in recent years. However, integrating multifrequency absorption, tunability, and high optical transparency into an absorber remains a crucial challenge. In this study, a multiband, tunable, and transparent microwave meta‐absorber is theoretically proposed and experimentally demonstrated. This meta‐absorber is composed of resonant patterns made from graphene and indium tin oxide (ITO), placed on a substrate of lithium niobate (LN). By introducing P‐type doping to reduce the resistance of monolayer graphene to around 300 Ω, the impedance matching of the absorber is promoted, consequently manifesting ten absorption points within 40 GHz. The electric field distribution analysis and an equivalent circuit model are employed to elucidate the physical mechanisms of the multiband absorber. Additionally, the lithium niobate dielectric layer possesses a substantial dielectric constant and exhibits phase transition characteristics with temperature changes. When the temperature increases to 250 °C, a comprehensive tuning range of more than 5.49 GHz within 40 GHz range is realized. The maximum tuning range for a single frequency point is 1.33 GHz. With the broadening of the band, the meta‐absorber can provide multiple tunable ranges, making it more favorable for practical applications in optical modulator and sensor.

AbstractSodium (Na) metal battery is regarded as one of the most promising candidates for large‐scale energy storage devices, benefiting from the abundant sodium reserves and low cost. However, its practical application is hindered by the dendrite growth and unstable electrode‐electrolyte interface. Herein, a 3D sodiophilic structure composed of a carbon matrix overlaid with g‐C3N4 coating layers (g‐C3N4/3D‐C) is designed to stabilize the Na plating/stripping behavior. The sodiophilicity is endowed by a highly reversible adsorption‐intercalation process at the hetero‐interface, which can guide conformal Na deposition and induce the formation of inorganic‐rich solid‐electrolyte interphases with high structural stability and fast Na‐ion transport. Meanwhile, the 3D scaffold can effectively accommodate Na deposition during Na plating/stripping and depress the dendrite formation. As a result, the half cell assembled with g‐C3N4/3D‐C electrode delivers long‐term cycling performance at 1.0 mA cm−2 with a high Coulombic efficiency of 99.92% for over 2000 cycles and of 99.94% even at 5 mA cm−2, 10 mAh cm−2. The practical feasibility of the g‐C3N4/3D‐C is verified with full cells, which shows favorable rate capability and long‐cycle performance. The sodiophilic hetero‐interface construction strategy proposed in this work sparks new insights for designing high‐performance Na metal anodes.

AbstractThe effectiveness of frequent compost application in improving soil health is well‐documented. Less is known on the long‐term effects of infrequent compost application to semiarid soils. Compost made of dairy manure and straw bedding was applied once in a dryland organic hard red winter wheat (Triticum aestivum L. emend. Thell.)–fallow system at 50 Mg ha−1 dry wt. in 1994 in a randomized complete block design with three replicates. Twenty‐eight years later, yields in composted plots (1.4 Mg ha−1) remained higher (p < 0.1) than in control plots (0.79 Mg ha−1). Plant‐available P, acid phosphatase activity (ACP), and total N were higher in composted plots by 143%, 37%, and 29%. Soil organic carbon (SOC) and dehydrogenase enzyme activity were greater by 25% and 20% with compost compared to the control, as were aggregate stability determined using SLAKES method, autoclave‐extractable protein, and CO2‐96 h by 143%, 22%, and 16%. Soil extractable K and Zn also increased with compost application. The interaction of ACP and estimated evapotranspiration (ET) emerged as a pivotal factor in explaining the variation in yield. These findings suggest that growers may see some yield improvements from periodic compost applications to dryland organic winter wheat–fallow systems. This strategy could help rebuild SOC and partially counter the challenges of low and variable precipitation.

ABSTRACTBiallelic variants in NRROS are associated with the rare entity of seizures, early‐onset, with neurodegeneration and brain calcification (SENEBAC). Here, we report a novel loss of function variant c.720G>A, p.(Trp240*) in a patient with the clinical presentation of developmental regression, refractory seizures, and intracranial calcification. The notable clinical features included normal early development followed by regression of milestones, dysmorphism, microcephaly, refractory seizures, absent deep tendon reflexes, and hypotonia. Neuroimaging features included cerebral atrophy, thin corpus callosum, and white matter calcifications. The phenotype observed in the current report overlaps strongly with the reported phenotype in literature; however, areflexia and dysmorphic features have not been reported before with this entity. A total of 11 individuals have been reported to date. Here, we present a detailed description of the phenotype in an Indian child, expanding the clinical and molecular spectrum of NRROS‐related syndrome.

AbstractAprotic Li‐CO2 batteries suffer from sluggish solid‐solid co‐oxidation kinetics of C and Li2CO3, requiring extremely high charging potentials and leading to serious side reactions and poor energy efficiency. Herein, we introduce a novel approach to address these challenges by modulating the reaction pathway with tailored Pt d‐electrons and develop an aprotic Li‐CO2 battery with CO and Li2CO3 as the main discharge products. Note that the gas‐solid co‐oxidation reaction between CO and Li2CO3 is both kinetically and thermodynamically more favorable. Consequently, the Li‐CO2 batteries with CoPt alloy‐supported on nitrogen‐doped carbon nanofiber (CoPt@NCNF) cathode exhibit a charging potential of 2.89 V at 50 μA cm−2, which is the lowest charging potential to date. Moreover, the CoPt@NCNF cathode also shows exceptional cycling stability (218 cycles at 50 μA cm−2) and high energy efficiency up to 74.6 %. Comprehensive experiments and theoretical calculations reveal that the lowered d‐band center of CoPt alloy effectively promotes CO desorption and inhibits further CO reduction to C. This work provides promising insights into developing efficient and CO‐selective Li‐CO2 batteries.

Published: October 2024

AbstractThe glycosylation of peptides and proteins can significantly impact their intrinsic properties, such as conformation, stability, antigenicity, and immunogenicity. Current methods for preparing N‐linked glycopeptides typically rely on amide bond formation, which can be limited by the presence of reactive functional groups like acids and amines. Late‐stage functionalization of peptides offers a promising approach to obtaining N‐linked glycopeptides. In this study, we demonstrate the preparation of N‐linked glycopeptides through a photoredox‐catalyzed site‐selective Giese addition between N‐glycosyl oxamic acid and peptides containing dehydroalanine (Dha) under visible light conditions. Unlike traditional methods that rely on the coupling of aspartic acid and glycosylamine, this approach utilizes the conjugation of N‐glycosylated carbamoyl radicals with Dha, facilitating the straightforward modification of complex peptides.
