In this article, a systematic investigation into the corrosion and discharge behaviors of as‐rolled a represents aluminum, Z represents zinc, 9 and 1 represent their respective contents of 9% and 1% in the alloy (AZ91) magnesium alloy after electro pulsing treatment (EPT), considering rolling deformations of 0% (as‐cast AZ91 magnesium alloy), 20%, 30%, and 40%, is presented. In this investigation, immersion weight loss tests, electrochemical tests, and other experimental methods are employed. In the results, it is revealed that the content of the β‐Mg17Al12 phase gradually decreases with increasing rolling deformation after EPT. Notably, the highest content of β‐Mg17Al12 phase and the most outstanding corrosion resistance are achieved with as‐cast AZ91 magnesium alloy. Furthermore, at low current densities (5 and 10 mA cm−2), the 30% rolling deformation exhibits superior discharge activity, while the discharge activity of the 40% rolling deformation is most excellent at high current densities (40 and 50 mA cm−2). The microstructure observations support these findings, highlighting the close relationship between the corrosion resistance and discharge activity of as‐rolled AZ91 magnesium alloy after EPT, and the content of the β‐Mg17Al12 phase and the area of high‐energy grain boundaries.

AbstractThe poor deformation ability of magnesium rods makes it challenging to fabricate long MgB2 inner magnesium diffusion (IMD) wires, further seriously limiting the application of high‐performance MgB2 wires. A 600 m IMD 30‐filament MgB2 wire is fabricate by alternating use of rotary‐swaging and drawing strategy. The critical current density (Jc) and the critical engineering current density (Je) are 8.0 × 104 A cm−2 and 7.6 × 105 A cm−2 (at 4.2 K, 4 T), respectively, which are some of the best performances reported so far. The flux‐pinning behavior of the MgB2 wires is investigated, and the surface pinning behavior is found to be dominant in the IMD 30‐filament wire in the whole field range at 4.2 K. The critical point for the IMD 30‐filament MgB2 wire to keep high performance in high fields is revealed by comparing it with the reference wires. Then, 520 m of wire are cut from the 30‐filament MgB2 wire and wound into a coil. The center field of the coil is 5.71 T at 4.2 K when the current loads to 219 A, which is the highest value among the IMD MgB2 coils. This work made breakthroughs in the wire length, filament numbers, and transport performance of IMD MgB2 wire, while also providing a paradigm study for exploring the in situ magnetic performance of multi‐filament wires.

AbstractClassical photoresists utilized in direct laser writing (DLW) rely on photoinitiators and radical polymerization mechanisms to induce the cross‐linking process. Herein, a simple initiator‐free photoresist is introduced that enables the rapid fabrication of intrinsically thermally degradable 3D microstructures via DLW. The reported photoresist exploits the [2 + 2] photo‐dimerization reaction of a multifunctional monosubstituted thiomaleimide compound while harvesting on‐demand microstructure degradation through the intrinsic thermally reversible nature of the photocrosslinks. The photoresist exceeds attainable DLW printing speeds for non‐chain growth resins, readily attaining 1500 µm s−1 and up to 5000 µm s−1, making it a promising system to compete with traditional photo‐initiator containing resists while introducing on‐demand post‐printing degradability.

AbstractHarnessing energy from underwater bubbles has garnered significant attention, particularly for powering off‐grid circuitry. However, the efficiency of bubble‐driven liquid‐solid interface charge transfer remains low. This research unveils a phenomenon: accelerated bubble slippage enhances liquid‐solid interfacial charge transfer. Building upon this discovery, a pulse bubble‐based power generation technique is proposed, achieving an energy density of 24.2 mJ L−1 generated by pulsed bubbles. The crux of pulse bubble power generation lies in the precise control of impact velocity. By meticulously regulating the impact kinetic energy of bubbles, the accumulated potential energy of multiple small bubbles is converted into instantaneous pulse kinetic energy. A typical pulse bubble is controlled within a 72 ms timeframe, unleashing a surge of energy that can directly illuminate 400 light‐emitting diodes. This approach represents a groundbreaking advancement in underwater energy harvesting technology, dramatically expanding its potential applications.

AbstractAn anionic‐additive electrolyte system is introduced by incorporating Lithium tetrafluoroborate (LiBF4) into a conventional base electrolyte for high‐voltage LiNi₀.₅Mn₁.₅O₄ (LNMO) cathodes in lithium‐metal batteries. At high voltages, the sacrificial oxidation of LiBF4 mitigates electrolyte degradation and forms a robust cathode electrolyte interface (CEI) enriched with boron and fluorine‐based components, which protects against active material corrosion. Density Functional Theory (DFT) studies reveal that BF₄⁻ is more readily oxidized, while MD simulations validate the CEI's inorganic composition. Initial cycling with a specialized charge‐discharge protocol ensures optimal use of the additive, resulting in a uniform, thin (4–6 nm) CEI on the LNMO cathode. The CEI formed in anionic‐additive electrolyte system effectively suppresses transition metal dissolution and surface degradation, enhancing long‐term cycling performance. The LiBF4‐enhanced electrolyte also lowers overpotential and promotes more uniform Li deposition compared to the base electrolyte. At a 1 C‐rate, the LNMO cathode with a Li metal anode and optimized electrolyte achieves a discharge capacity of 115 mA h g⁻¹ and an energy density of 540 Wh kg⁻¹ over 500 cycles. These findings underscore LiBF4’s dual role in protecting LNMO cathodes and Li metal anodes, highlighting the critical role of additives in CEI development for advanced lithium‐metal batteries.

AbstractElectrolyte additive engineering is a feasible protocol in improving Zn anode stability. Typical additive designs center on the regulation of Zn deposition; nevertheless, versatile additives are urgently requested to comprehensively manage the surface landscape, interface physicochemistry, and by‐product elimination. Here, a straightforward strategy is presented to meet such needs employing an environmentally‐friendly chelator, hydroxyethyl‐ethylenediaminetriacetate acid (HEDTA), as an additive for ZnSO4 electrolyte. Throughout theoretical computations and experimental investigations, it is demonstrated that protons released from the gradual ionization of HEDTA during rest periods aid in the mild engraving of the Zn surface. Both the amino and carboxyl groups of HEDTA⁻ can be protonated, which effectively buffers the interfacial pH value in the entire battery lifespan and eliminates the formation of by‐products. The HEDTA− anions can also adsorb onto the Zn surface, helping facilitate Zn2⁺ mass transfer and accelerate the desolvation process. Benefiting from the synchronous modulation of surface topography and interfacial physicochemistry, the assembled half cells affording HEDTA additive maintain a durable operation of up to 8821 cycles at 5.0 mA cm−2/1.0 mAh cm−2. Additionally, symmetric cells manifest stable cycling for over 4600 h at 0.5 mA cm−2/0.25 mAh cm−2.

AbstractUnderstanding the myofibroblast microenvironment is critical to developing therapies for fibrotic diseases. Here the development of a novel human tendon‐on‐a‐chip (hToC) is reported to model this crosstalk in peritendinous adhesions, which currently lacks biological therapies. The hToC facilitates cellular and paracrine interactions between a vascular component, which contains endothelial cells and monocytes, and a tissue hydrogel component that houses tendon cells and macrophages. It is found that the hToC replicates some aspects of in vivo inflammatory and fibrotic phenotypes in preclinical and clinical samples, including activated mTOR signaling, vascular inflammation, tissue contraction induced by myofibroblast activation, inflammatory cytokines secretion, and transendothelial migration of monocytes to the tissue hydrogel. Transcriptional analysis demonstrates significant overlap in enriched pathways in the hToC with human tenolysis samples, including the activation of mTOR signaling. Rapamycin suppresses the vascular inflammation and fibrotic phenotype in the hToC, which provides proof‐of‐concept of its utility as an in vitro tool for investigating multicellular crosstalk in fibrosis and testing therapeutics to mitigate it.

AbstractCell‐surface engineering holds great promise in boosting endogenous stem cell attraction for tissue regeneration. However, challenges such as cellular internalization of ligand and the dynamic nature of cell membranes often complicate ligand–receptor interactions. The aim of this study is to harness the innovative potential of programmable tetrahedral framework nucleic acid (tFNA) to enable precise, tunable ligand–receptor interactions, thereby improving stem cell recruitment efficiency. This approach involves experimental screening and theoretical analysis using dissipative particle dynamics. The results demonstrate that altering the flexibility and topology of ligands on tFNA changes their cellular internalization and membrane binding efficiency. Furthermore, optimizing the distribution of the mesenchymal stem cell (MSC)‐binding aptamer 19S (Apt19S) on the tFNA enhances the stem cell capture efficiency. Following successful in vitro MSC capture, Apt19S‐modified tFNA is chemically linked to a hyaluronic acid hydrogel, forming an efficient “stem cell catcher” system. Subsequent in vivo experiments demonstrate that this system effectively promotes early stem cell recruitment and accelerates bone regeneration in different bone healing scenarios, including cranial and maxillary defects.

AbstractThe integration of multiple elements in a high‐entropy state is crucial in the design of high‐performance, durable electrocatalysts. High‐entropy metal hydroxide organic frameworks (HE‐MHOFs) are synthesized under mild solvothermal conditions. This novel crystalline metal–organic framework (MOF) features a random, homogeneous distribution of cations within high‐entropy hydroxide layers. HE‐MHOF exhibits excellent electrocatalytic performance for the oxygen evolution reaction (OER), reaching a current density of 100 mA cm−2 at ≈1.64 VRHE, and demonstrates remarkable durability, maintaining a current density of 10 mA cm−2 for over 100 h. Notably, HE‐MHOF outperforms precious metal‐based electrocatalysts despite containing only ≈60% OER active metals. Ab initio calculations and operando X‐ray absorption spectroscopy (XAS) demonstrate that the high‐entropy catalyst contains active sites that facilitate a multifaceted OER mechanism. This study highlights the benefits of high‐entropy MOFs in developing noble metal‐free electrocatalysts, reducing reliance on precious metals, lowering metal loading (especially for Ni, Co, and Mn), and ultimately reducing costs for sustainable water electrolysis technologies.

AbstractFull‐spectral optical camouflage is of broad interest and in urgent demand because of everlasting safety pursuit in modern society. However, the widely existing dim scenarios call for not only broadband low thermal detectivity but also wide‐gamut camouflaging colors with both low lightness and minimal chromatism. Here, a tape‐like metamaterial (meta‐tape) with broad spectral manipulation bandwidth from visible to mid‐infrared is demonstrated. The ultrathin meta‐tapes can exhibit different colors with wide gamut and low lightness from 20 to 40, enabling low color difference under various backgrounds down to 1.2 L*a*b*. The infrared emissivity is simultaneously suppressed down to 3.8% across 3 – 14 µm. The outstanding optical performances are well preserved under various mechanical and thermal stability tests. The pronounced multispectral camouflage, combined with flexible and robust tape‐like nature, makes the meta‐tape a promising solution for VIS‐IR compatible camouflage in diverse scenarios.

Published: November 2024

AbstractThe sluggish kinetics of hydrogen evolution reaction (HER) via water reduction limits the efficiency of alkaline water electrolysis. The HER kinetics is not only intimately related to the catalyst surface structure but also relevant to the cation identity of the electrolyte. The cation dependence also relies on the surface electronic structure and applied potential, but this interrelated effect and its underlying mechanism awaits elucidation. Herein, differently‐charged molybdenum sulfide (MoSx) cluster supports ([Mo3S13]2− and [Mo3S7]4+) are utilized to hybridize with the identical metallic Ru centers. The specific electrostatic interaction between MoSx clusters and Ru precursors induces different Ru valences of the hybrids, with a higher valence state for Ru/Mo3S13 endowing a higher activity. The Ru/Mo3S13 and Ru/Mo3S7 exhibited drastically‐different cation dependence, in which the charged support determines the local accumulation of cations and resulting water structures. The more negatively‐charged Mo3S13 support induces the facile accumulation of cations, especially for less‐hydrated K+ cations. The water activation capability by Ru valences and cation accumulation from the support effect in‐together determine the cation‐dependent alkaline HER activity. This work not only enriches the understanding about the cation‐dependent HER mechanism but also shines a light on the rational optimization strategy of electrode/electrolyte interfaces.

AbstractPhysical blending of fully π‐conjugated polymers (FπCPs) is an effective strategy to achieve intrinsically stretchable films for the fabrication of flexible optoelectronic devices, but easily causes phase separation, nonuniform morphology and uncontrollable photo‐electronic processing. This may cause low efficiency, unstable and nonuniform emission, and poor color purity, which are undesirable for deep‐blue flexible polymer light‐emitting diodes (FPLEDs). Herein, a “Like Dissolves Like” design principle to prepare semiconductor fluid plasticizers (SFPs) is established and intrinsically stretchable FπCPs films via external plasticization for high‐performance deep‐blue FPLEDs are developed. Three fundamental requirements are proposed, “similar conjugated skeleton, similar molecular polarity, and similar electronic structures,” to prepare model‐matched nonpolar M1 and polar M2 plasticizers for poly(9,9‐dioctylfluorene) (PFO). Large‐area plasticized PFO films exhibit an efficient, narrowband, and stable ultra‐deep‐blue electroluminescence (FWHM < 40 nm, CIE: 0.12, 0.04), uniform morphology, and excellent intrinsic stretchability (fracture strain >20% and crack‐onset strain >120%). Efficient and uniform deep‐blue FPLEDs based on stretchable PFO films are fabricated with a high brightness of ≈3000 cd cm−2. Finally, blended PFO films exhibit outstanding stretch‐deformation cycling stability of their deep‐blue electroluminescent behavior, confirming the effectiveness of the “Like Dissolves Like” principle to design matched SFPs for stretchable FπCP films in flexible electronics.

AbstractDeveloping high‐performance aqueous symmetric all‐organic batteries (SAOBs) by replacing metal‐based batteries or batteries with organic electrolytes is highly attractive to achieve a greener rechargeable world. However, such a new energy storage system still exhibits unsatisfactory rate capability and cycling stability due to the limitations in electrode materials screening. Here, a novel covalent organic framework (COF) containing abundant CN and CO for the electrode material is designed, which is combined with graphene and assembled into all‐COF/graphene batteries for the first time. Moreover, the co‐storage of Zn2+ and H+ in COF can be achieved in a mild aqueous electrolyte. Impressively, benefiting from the extended porous structure of COF, plentiful active reaction sites, more extensive electron delocalization from CO modification at molecular level, as well as enhanced fast H+ storage capacity of graphene and CO in COF, this kind of SAOBs show excellent cycle life and high rate performance (over 15000 cycles with a capacity of 80 mAh g−1 at a high current density of 5 A g−1 in pouch cell). This work will open a new window for the design of high‐performance aqueous organic batteries, further moving toward a more eco‐friendly electrochemical world.

AbstractHemodialysis is crucial for patients with end‐stage renal disease, yet evaluating its operating parameters often requires complex mathematical models. To simplify this process, user‐friendly modules have been developed to accurately assess key parameters with minimal inputs, enabling users to track disease prognosis. These modules incorporate governing equations and allow straightforward analysis. Validation against experimental data from polymer membrane studies demonstrated that at a blood flow rate of 300 mL min−1, the model predicted a clearance of 262 mL min−1, showing 7% difference from the actual value of 281 mL min−1. At a dialysate flow of 400 mL min−1, the model's predicted clearance was 286.47 mL min−1, with only a 1% difference compared to previous model. The module also showed 40% higher clearance in counter‐current flow compared to co‐current, with a 47% difference at 400 mL min−1 dialysate flow. Increasing the hollow fibre length from 27 to 50 cm led to a 4% clearance increase. Additionally, increasing residual renal clearance by 0.5 mL min−1 doubled the standard Kt V−1 Kt/V, and similar effects were seen by increasing weekly hemodialysis sessions. The app allows simulations, plots, and comparisons with minimal inputs and can be integrated into MATLAB or other platforms, benefiting both patients and researchers in prognosis and treatment analysis.

Published: November 2024

AbstractThin semiconducting films of magnesium doped indium‐ and tin oxide are prepared by thermal atomic layer deposition (ALD). The metal oxide films are deposited at 200 °C from the precursors trimethylindium, tetrakis(dimethylamido)tin, bis(ethylcyclopentadienyl)magnesium and water as oxidant. These thin‐films are observed to be amorphous by electron microscopy and X‐ray diffraction. However, they exhibited a near‐range atomic order with correlation lengths of up to 10 Å, as demonstrated by high energy total scattering at grazing incidence employing synchrotron radiation. Even minor alterations in composition reveal a significant impact on the thin‐film transistor (TFT) device parameters, due to magnesium's high oxygen binding capability and its ability to inhibit the formation of oxygen vacancies, resulting in a decrease of free charge carriers in the material. Stability tests indicate a device degradation after storage in ambient conditions due to water adsorption on the surface, which could be reversed by an additional annealing step which qualify the films as robust. This studie demonstrate the possibility of employing minor amounts of high band gap oxides such as MgO to manipulate and control the electric behavior of the active channel layer performance in inorganic TFT devices.
