Low‐Hysteresis and Tough Ionogels via Low‐Energy‐Dissipating Cross‐Linking
Authors: Sun Bin , Liu Kai , Wu Baohu , Sun Shengtong , Wu Peiyi 
Published: August 2024

AbstractLow‐hysteresis merits can help polymeric gel materials survive from consecutive loading cycles and promote life span in many burgeoning areas. However, it is a big challenge to design low‐hysteresis and tough polymeric gel materials, especially for ionogels. This can be attributed to the fact that higher viscosities of ionic liquids (ILs) would increase chain friction of polymeric gels and eventually dissipate large amounts of energy under deformation. Herein, a chemical design of ionogels is proposed to achieve low‐hysteresis characteristics in both mechanical and electric aspects via hierarchical aggregates formed by supramolecular self‐assembly of quadruple H‐bonds in a soft IL‐rich polymeric matrix. These self‐assembled nanoaggregates not only can greatly reinforce the polymeric matrix and enhance resilience, but also exhibit low‐energy‐dissipating features under stress conditions, simultaneously benefiting for low‐hysteresis properties. These aggregates can also promote toughness and subsequent anti‐fatigue properties in response to external cyclic mechanical stimuli. More importantly, these ionogels are presented as a model system to elucidate the underlying mechanism of the low hysteresis and fatigue resistance. Based on these findings, it is further demonstrated that the supramolecular low‐hysteresis strategy is universal.

AbstractOwing to the considerable capacity, high safety, and abundant zinc resources, zinc‐ion batteries (ZIBs) have been garnering much attention. Nonetheless, the unsatisfactory cyclic lifespan and poor reversibility originate from side reactions and dendrite obstacles to their practical applications. In addition to inhibiting the corrosion of aqueous electrolytes, regulating planar deposition is a key strategy to enhance their long‐term stability. Herein, an in situ conversion strategy is reported to construct a protective “dual‐layer” structure (VZSe/V@Zn) on zinc metal, consisting of the VSe2‐ZnSe outer layer with low lattice mismatch to Zn (002) plane, and corrosion‐resistant nanometallic V inner layer. Such design integrates superior interfacial ionic/electronic transfer, corrosion resistance, and unique planar deposition regulation capability. The as‐prepared VZSe/V@Zn demonstrates remarkable durability of 238 h at 50 mA cm−2 with a high depth of discharge (68.3% DOD) in the Zn||Zn symmetric cell. Even in the anode‐free system, the as‐prepared protective layer can extend the cycle life up to 2000 cycles, with an outstanding capacity retention of 93.1% and ultra‐high average coulombic efficiency of 99.998%. This work delineates an effective strategy for fabricating lattice‐matching protective layers, with profound implications for elucidating zinc deposition mechanisms and paving the way for the development of high‐performance zinc batteries.

AbstractLanthanide downconversion nanoparticles (DCNPs) have huge potential in biosensing and imaging applications in the NIR‐II window. However, DCNPs inherently suffer from low quantum efficiency, due to low absorption cross‐section and the restricted doping concentration of lanthanide ions. In this work, a combined strategy for downconversion luminescence in the NIR‐II window is investigated by the integration of Ce3+ ions into the conventional NaYF4: Yb3+, Er3+ DCNPs and incorporation of periodic silver hole‐cap coupled Nanoarrays (Ag‐HCNAs) simultaneously. Over two orders of magnitude, luminescence enhancement is achieved by the combination of optimized Ce3+ doping and plasmonic effects, compared to NaYF4: Yb3+, Er3+ DCNPs immobilized on the glass substrate. Moreover, 3D Finite‐Difference Time‐Domain (FDTD) simulations and time‐resolved luminescence measurements are combined to gain important insights into the mechanism of downconversion luminescence enhancement. The results show that there is a large electric field enhancement between the Ag nanoholes and the Ag hemisphere cap at 980 nm (excitation enhancement), while the lifetime shortening at 1525 nm revealed an increased radiative decay rate and enhanced quantum yield (emission rate enhancement). The strategy for downconversion luminescence enhancement demonstrated in this work holds a significant potential for advancing the next generation biosensing and bioimaging based on DCNPs in the NIR‐II window.

AbstractNanowire‐based plasmonic lasers are now established as nano‐sources of coherent radiation, appearing as suitable candidates for integration into next‐generation nanophotonic circuitry. However, compared to their photonic counterparts, their relatively high losses and large lasing thresholds still pose a burdening constraint on their scalability. In this study, the lasing characteristics of zinc oxide (ZnO) nanowires on silver (Ag) and aluminum (Al) substrates, operating as optically‐pumped short‐wavelength plasmonic nanolasers, are systematically investigated in combination with the size‐dependent performance of the hybrid cavity. A nanomanipulation‐assisted single nanowire optical characterization combined with high‐throughput photoluminescence spectroscopy enabled the correlation of the lasing characteristics to the metal substrate and the nanowire diameter. The results evidence that the coupling between excitons and surface plasmons is closely tied to the relationship between substrate dispersive behavior and cavity diameter. Such coupling dictates the degree to which the lasing character, be it more plasmonic‐ or photonic‐like, can define the stimulated emission features and, as a result, the device performance.

Published: August 2024

AbstractJanus metasurfaces, offering versatile light manipulation contingent on incident direction, are explored across microwave to mid‐infrared spectra. Nonetheless, prior designs often resort to spatial multiplexing or vertical stacking, entailing complex fabrication. Metallic Janus metasurfaces, owing to material properties, suffer notable Ohmic losses in the visible spectrum. In this study, Single‐layer TiO2‐based Janus metasurfaces with arbitrary polarization control is experimentally demonstrated, exhibiting directionally asymmetric functionalities in spin and orbital angular momentum (OAM). A novel Jones matrix formulation tailored for Janus metasurfaces is presented, enabling efficient generation of two asymmetric, high‐purity OAM states of vortex beams at wavelength of 532 nm, contingent on incidence direction. This innovation facilitates compact and versatile phase manipulation, encompassing applications such as lasers and optical combiners, thereby expanding its utility across diverse domains.

Published: August 2024

AbstractDecoupling of phase and polarization is significant for multidimensional light manipulation. However, this requires traditional cascaded and parallel optical elements, resulting in a bulky and complex system. Metasurfaces can potentially replace complex optical modules as novel ultrathin planar optical elements. Herein, an ultrathin single‐layer metasurface is proposed to decouple the phase and polarization based on the Pancharatnam–Berry phase. The rotation angles of the two nanofins are employed to manipulate the phase and polarization independently, significantly simplifying the design process. Diffraction‐limited focusing with a degree of linear polarization higher than 95% is achieved for wavelengths in the 405–633 nm range. Furthermore, a metasurface can arbitrarily manipulate the relative intensity between different channels. The intensity ratio is adjusted from 0.12 to 6.62. These results will pave the way for miniaturized, integrated, and multi‐channel optical elements.
Design of Aggregation‐Induced Emissive Multiwalled Tubules for Efficiently Sequential Light Harvesting

Published: August 2024

AbstractIn the endeavor to mimic natural light‐harvesting systems (LHSs), a persistent challenge has been the tendency of synthetic materials to adopt spherical architectures rather than the desired multitubular structures found in nature. In this study, a novel carboxylbetaine‐type zwitterionic surfactant with aggregation‐induced emission (AIE) properties is designed. By coassembling with anionic surfactants, multiwalled tubules comprising bilayer membranes ≈5 nm thick are successfully constructed. With AIE fluorophores densely packed at the center, their AIE properties are triggered to serve as an efficient antenna for light harvesting and energy transfer. This facilitated high antenna effects via energy transfer from cyan fluorescent donor to yellow fluorescent acceptor and then to red fluorescent acceptor. Additionally, the emission color can be adjusted from blue to red by manipulating the donor/acceptor/acceptor ratio, with pure white‐light emission achievable at specific ratios. This achievement not only realizes the construction of efficient sequential LHSs but also offers inspiration for the future design of artificial multitubular systems.

AbstractDue to the nature of the aqueous operation characteristics of photoelectrochemical‐type (PEC) optoelectronic devices, it is vital to manipulate the semiconductor/electrolyte interfacial properties to synergistically regulate the photogenerated carrier separation, charge transport in semiconductors, and interfacial charge transfer. In this work, it is demonstrated that sulfur vacancy effectively manipulates the band structure of ZnS and works as electrochemical reaction active sites synchronously. ZnS with more sulfur vacancy forms a larger built‐in electric field at the ZnS/electrolyte interface, simultaneously boosting photogenerated charge separation efficiency and promoting charge transport in ZnS. The sulfur vacancy also functions as the interfacial electrochemical reaction active sites, thereby accelerating the interfacial electrochemical reaction kinetics and reducing photo‐oxidation behavior. Hence, the corresponding ZnS PEC photodetectors exhibit excellent self‐powered solar‐blind ultraviolet detection capability with ultrahigh responsivity of 241.71 mA W⁻1, fast rise/decay time of 15/15 ms, high detectivity of 8.9 × 1011 Jones, outstanding wavelength selectivity of 1343, and excellent stability (92.6% after 8‐month storage), which is one of state‐of‐the‐art PEC UV photodetectors. Furthermore, the prototype of an underwater wireless optical communication device is demonstrated using ZnS PEC photodetectors as the light signal receiver. This work endows new sight for ZnS applications in underwater optoelectronic devices.

Published: August 2024

AbstractProton exchange membrane water electrolysis (PEMWE) emerges as a promising avenue for storing excess renewable energy by generating H2 gas without introducing additional carbon emissions. However, PEMWE systems still grapple with challenges related to energy efficiency, cell longevity, and maximum operational current density. Consequently, extensive research efforts have been directed toward enhancing the performance of electrocatalysts and refining system designs to overcome these limitations. Within this framework, this study introduces a novel synthetic approach for fabricating N‐doped carbon matrices with a checkered pattern on the surface of porous transport layers (PTLs) composed of titanium (Ti). The resulting N‐doped checkered carbon matrices serve as robust hosts for Ir‐Ru nanoparticles during the oxygen evolution reaction (OER), ensuring their stable integration. Additionally, the checkered pattern of the N‐doped carbon matrices facilitates the efficient transport of both electrolyte and produced O2 gas. Capitalizing on these advantages, the incorporation of checkered carbon matrices with Ir‐Ru nanoparticles has achieved a cell current density of 6.82 A cm−2 at a unit cell voltage of 2.0 V. The benefits of this structural innovation extend beyond water electrolysis and can be extrapolated to other electrochemical systems involving the production and transport of gas bubbles, such as CO2 reduction.

AbstractIn the pursuit of sustainable hydrogen production via water electrolysis, paramount importance of electrocatalyst stability emerges as a defining factor for long‐term industrial viability. A thorough understanding and enhancement of stability not only ensure extended catalyst lifetimes but also pave the way for consistent and efficient hydrogen generation. This review focuses on the pivotal role of stability in determining the practical viability of oxygen evolution electrocatalysts (OECs) for large‐scale applications in water electrolysis for hydrogen production. The paper explores the pivotal role of stability over initial activity, citing examples and hypothetical scenarios. First, figures of merits for stability evaluation of the electrocatalyst are explained along with the available benchmarking protocols for stability evaluation. Further, the text delves into various strategies that can enhance the stability of the electrocatalyst which include self‐healing/regeneration pathway, oxygen evolution reaction (OER) mechanism optimization to achieve highly stable OER and stabilization of active metals atoms within the electrocatalyst to inhibit dissolution as a way forward for industrial application. The interplay of stability, activity, and cost is also explained to suit the industrial application of the electrocatalyst. Lastly, it outlines challenges, prospects, and future directions, presenting a guide for advancing OECs in the hydrogen generation landscape.

AbstractBackgroundThe advantages of robot‐assisted minimally invasive esophagectomy (RA‐MIE) over conventional minimally invasive esophagectomy (C‐MIE) are unknown. This nationwide large‐scale study aimed to compare surgical outcomes between RA‐MIE and C‐MIE using rigorous propensity score methods, including detailed covariates and relevant outcomes.MethodsThis Japanese nationwide retrospective cohort study included RA‐MIE or C‐MIE for esophageal malignant tumors performed between October 2018 and December 2019 and registered in the Japanese National Clinical Database. The primary outcome measure was postoperative complications classified as Clavien–Dindo Grade IIIa or higher. Propensity score matching was performed to create a balanced covariate distribution between the two groups.ResultsAfter propensity score matching, 1092 patients were selected. The RA‐MIE group had a significantly longer operation time and greater blood loss than the C‐MIE group (565 vs. 477 min and 120 vs. 90 mL). Furthermore, the R0 resection rate was lower in the RA‐MIE group than in the C‐MIE group (95.1% vs. 97.8%). The RA‐MIE and C‐MIE groups had no differences regarding overall complications ≥ Grade IIIa (22.0% vs. 20.3%, p = 0.52), 30‐day mortality rates (0.4% vs. 0.5%), and operative mortality rates (0.7% vs. 0.7%). Deep SSI was less frequent (2.7% vs. 6.0%) and pulmonary embolism was more frequent (2.4% vs. 0.5%) in the RA‐MIE group than in the C‐MIE group.ConclusionsIn the initial phase of implementation, RA‐MIE and C‐MIE demonstrated comparable morbidity rates when performed by skilled board‐certified endoscopic surgeons.
The gas–liquid mass transfer and pressure drop behaviors of the gas–liquid–liquid three‐phase flow in micro‐packed beds
Authors: Zhang Jingwei , Chen Zhuo , Xu Jianhong 
Published: August 2024

AbstractMicro‐packed bed reactors, due to their high mass and heat transfer efficiency, and inherent safety, have significant advantages in processes such as hydrogenation reactions, debenzylation reactions, and catalyst screening. Despite extensive studies on gas–liquid two‐phase flow in micro‐packed beds, research on gas–liquid–liquid three‐phase flow remains limited. This study investigates the mass transfer and pressure drop behaviors of gas–liquid–liquid three‐phase flow in micro‐packed beds. Experimental results reveal that gas–liquid mass transfer is influenced by dispersion and turbulence enhancements, as well as the secondary liquid phase. A mathematical model for mass transfer shows strong agreement with experimental data. Additionally, a pressure drop model, considering inertial, viscous, and interfacial tension forces, accurately predicts experimental results. These findings provide valuable insights for optimizing micro‐packed bed operations.

AbstractDirect CH4 to CH3OH conversion is a long‐standing grand challenge in catalysis. We present one‐step steam reforming of methane to methanol (OSRMtM) by combining an atmospheric pressure CH4/H2O/Ar plasma with a Cu/Mordenite (Cu/MOR) catalyst at 170°C, achieving 77% CH3OH selectivity with 3.0% CH4 conversion. Catalyst characterization and plasma diagnostics, as well as D2O and H218O‐labeled isotope tracer experiments reveal that the excellent reaction performance is attributed to Cu‐O active sites confined by MOR zeolite. During plasma‐catalytic OSRMtM, both CH4 and H2O are activated in the plasma and dissociated to produce radicals (CH3, OH, and H). These radicals drive the redox process between Cu2+ and Cu+, playing an important role in plasma‐catalytic OSRMtM. Although a gradual reduction of Cu2+ to Cu+ leads to slow deactivation, the catalytic performance can be completely recovered through simple calcination, which enables a continuous plasma‐catalytic OSRMtM process using a fluidized‐bed reactor.

ABSTRACTBy using a multicomponent reaction involving isatins, diamines or aminoalcohols, activated acetylenic compounds, haloketones, and ammonium acetate in aqueous media in the presence of Cu@Fe3O4/SiO2@MWCNTs as new catalyst, the novel pyridopyrroloindole was produced in high yields. This catalyst was produced by employing Petasites hybridus rhizome water extract as a green media and moderate base. The pyridopyrroloindole derivatives were newly synthesized compounds, and their antioxidant properties were assessed using the 2,2‐diphenyl‐1‐picrylhydrazyl (DPPH) radical trapping and ferric reducing ability of plasma (FRAP) experiments. The pyridopyrroloindole 6b showed higher performance than butylated hydroxytoluene (BHT) and tert‐butylhydroquinone (TBHQ) better results. This method is used to make pyridopyrroloindole derivatives, and it has the advantages of a quick reaction, high yields, and the ability to separate the products easily.

ABSTRACTSynthesis of 5‐alkynyl furopyrimidine nucleoside analogs, with free‐ribose groups, was carried out, and their biological activity was evaluated. The substituents introduced at the C‐5 included propargyl and homopropargyl alcohols, 4‐methylphenyl (p‐tolyl), and 4‐pentylphenyl substituted alkynyl groups (56%–88%). Subsequently, alkyne function was coordinated to dicobalt hexacarbonyl unit, yielding the corresponding dicobalt hexacarbonyl 5‐alkynyl furopyrimidine nucleosides (51%–75%). All compounds contained 4‐pentylphenyl group attached at the C‐6 position of the bicyclic base, in line with most active antiviral structures. The antiproliferative effect of these modified nucleosides on cancer cells of different phenotypes was determined using in vitro studies. The tested compounds show antiproliferative effects with median inhibitory concentration (IC50) values of 16–23 and 9–15 μM for HeLa and K562 cells, respectively. The determination of reactive oxygen species (ROS) formation in K562 cells in the presence of modified nucleosides may suggest that the mode of action of the examined compounds may be attributed to the induction of oxidative stress.
