Published: December 2024

AbstractWith the improvement of implant design and the expansion of application scenarios, orthopedic implants have become a common surgical option for treating fractures and end‐stage osteoarthritis. Their common goal is rapidly forming and long‐term stable osseointegration. However, this fixation effect is limited by implant surface characteristics and peri‐implant bone tissue activity. Therefore, this review summarizes the strategies of interface engineering (osteogenic peptides, growth factors, and metal ions) and treatment methods (porous nanotubes, hydrogel embedding, and other load‐release systems) through research on its biological mechanism, paving the way to achieve the adaptation of both and coordination between different strategies. With the transition of the osseointegration stage, interface engineering strategies have demonstrated varying therapeutic effects. Especially, the activity of osteoblasts runs almost through the entire process of osseointegration, and their physiological activities play a dominant role in bone formation. Furthermore, diseases impacting bone metabolism exacerbate the difficulty of achieving osseointegration. This review aims to assist future research on osseointegration engineering strategies to improve implant‐bone fixation, promote fracture healing, and enhance post‐implantation recovery.

AbstractAlthough functional layers of quantum dot light‐emitting diodes (QLEDs) can be fabricated by solution processing, expensive vacuum deposition techniques are still required to form the top electrode, which hinders the commercialization of QLEDs. Here, efficient non‐vacuum QLEDs with a bi‐layer eutectic gallium‐indium (EGaIn) top electrode consisting of a viscous EGaIn layer and a liquid EGaIn interface layer is demonstrated. Due to the low flowable properties of the viscous EGaIn, bi‐layer EGaIn electrodes can be patterned directly by laser ablation with a narrow line width of 30 µm. As a result, non‐vacuum QLEDs with an excellent external quantum efficiency (EQE) of 30.49% are obtained, and by using poly(3,4‐ethylenedioxythiophene) polystyrene sulfonate as the bottom electrode, fully solution‐processed (including electrodes) non‐vacuum QLEDs with an EQE exceeding 24% are further achieved. Moreover, by precisely patterning the bi‐layer EGaIn electrode, the non‐vacuum QLED with high‐precision emission patterns (line width: 30 µm) can also be realized. To the best of the knowledge, these efficiencies are the highest ever reported for the non‐vacuum QLEDs. It is believed that the demonstrated high‐efficiency non‐vacuum QLEDs, with high‐precision patternable electrodes and low manufacturing cost, will advance the commercialization of QLEDs in displays.

AbstractThermochromic smart windows have attracted widespread attention in the field of solar modulation and building energy conservation. However, current materials of smart windows are still confronted with challenges, including low integrated luminous transmittance (Tlum), low solar energy modulation (ΔTsol), weak mechanical properties, and invariable critical transition temperature (τc). Herein, hydrophobic polyether side chains, that can reversibly undergo adjustable temperature‐triggered hydrophobic association, are introduced to thermochromic hydrogels for the first time. Due to the reversible phase separation, the obtained hydrogels demonstrate high Tlum (92.69%), high ΔTsol (82.15%), widely adjustable τc and fast transition rate (<4 s). Furthermore, the adjustable τc of hydrogel is independent of component changes, attributed to the rearrangement of physical‐crosslinked chain segments at various temperatures. Moreover, strong hydrogen bond and high entanglement endow the hydrogel with outstanding mechanical properties (tensile strength >0.45 MPa, elongation >440%). The results of simulation investigations in different cities illustrate that the hydrogels have excellent solar modulation and temperature regulation capabilities. Meanwhile, the thermochromic hydrogel possesses remarkable 3D‐printability and real‐time state monitoring capability, meeting the requirements of different climates and practical application. Therefore, the strategy proposed in this work provides innovative insights for thermochromic hydrogel smart windows and building energy conservation.

Published: December 2024

AbstractReconfigurable field‐effect transistors (RFETs) are a cutting‐edge research area that can significantly impact future advancements in electronics and computing. While various RFETs with diverse functionalities are actively reported in recent studies, further research efforts are imperative to explore RFETs with broader capabilities. Herein, a photoinduced reconfigurable transistor (PIRT) that alters its transport characteristics is presented in response to visible light using titanium dioxide nanoparticles encapsulated by an amphiphilic polymer (TiAP)/indium–gallium–zinc‐oxide heterojunction. The photo‐generated electrons and holes resulting from the photoionization of oxygen vacancies within the TiAP layer facilitate reversible switching between binary transistor and synaptic transistor modes. Utilizing these features, reconfigurable logic gates that function as both a digital NOT gate and a synaptic comparator depending on light exposure are developed. Additionally, a PIRT‐based in‐memory computing array is developed to perform multiply–accumulate operations, thus highlighting its potential for efficient, high‐density computing applications.

AbstractThe characteristic of materials with special strength and toughness is distinguished by the uniform arrangement of their multi‐level structures, which is a key factor that significantly affects their mechanical behavior and overall performance. This work explores the challenges and potential solutions to enhance the mechanical properties of hydrogels through the construction of multi‐scale, multi‐layered ordered uniform structures. A novel approach termed macromolecular network uniformization (MNU) that utilizes rotation ice templates to freeze‐cast uniform polymer networks in hydrogels is proposed. By integrating this process with salt‐out densification, hydrogels with exceptional toughness exceeding 350 MJ m⁻3 in both x and y directions with super‐high tensile stress (20 MPa) and strain at break (3000%), are obtained. This research effectively addresses the inherent limitation of hydrogel materials, which are primarily composed of hydrophilic polymers, limiting their potential for functional diversity and enhanced performance. To overcome this, the expansion of the hydrogel matrix is demonstrated to include hydrophobic polymers such as polycaprolactone (PCL) and polyacrylonitrile (PAN), thanks to the high solubility of DMSO. The MNU technique effectively produces high‐performance hydrogels with enhanced mechanical properties, increasing substrate diversity and enabling the development of durable hydrogel materials for various applications.

AbstractElectrolyte additives (EAs) are cost‐effective for stabilization of lithium metal batteries (LMBs). Nevertheless, most EAs are gradually consumed during the lithium deposition process, rendering them inadequate for long‐term cyclability. Herein, a novel hybrid metal–organic framework (MOF)‐based non‐expendable additive is prepared through polymerization of pentaerythritol tetraacrylate (PETEA) on a zeolitic imidazolate framework (ZIF‐67). Owing to the partial coating by PETEA‐based polymer, the exposed unsaturated metal sites of ZIF‐67 still attenuate the interaction between lithium ions (Li+) and anions, enabling rapid electrochemical kinetics and uniform Li deposition. Concurrently, the polymerized PETEA partially enters the Li+ solvation sheath and expels some organic solvents through Van der Waals interactions, which promotes the derivation of an inorganic‐rich SEI and inhibits dendrite formation. Accordingly, this additive‐contained Li||Li symmetric cell exhibits a stability over 1200 h with a small overpotential of 75 mV. Additionally, the assembled Li||LiFePO4 full cells with negative/positive ratio of 1.76 delivers a stable cyclability over 400 cycles at 0.5 C. Moreover, the Li||LiNi0.8Mn0.1Co0.1O2 high‐voltage full cell displays an impressive capacity retention of 80% over 311 cycles at 0.5 C. This study provides a valuable guidance to design non‐expendable multifunctional EAs for advancing high‐performance LMBs.

Published: December 2024

AbstractThe application of aqueous zinc‐ion batteries in large‐scale energy storage systems is significantly limited by the hydrogen evolution reaction (HER). Although conventional pH‐adjusting additives can reduce the overpotential of HER, it is imperative to simultaneously modulate the composition of the solid electrolyte interphase (SEI) and the electrical double layer (EDL) structure to enhance the utilization of zinc metal. This research develops a multifunctional pH‐controlling additive, the bis(2‐hydroxyethyl)amino‐tris(hydroxymethyl)methane (BT). First, the addition of BT increases the pH of the electrolyte to 5.9, which is within its effective buffer zone, and simultaneously reduces the HER potential to −1.107 V versus Ag/AgCl. Second, the inhibitory effect on HER can be further enhanced by the preferential adsorption of BT molecules containing multiple hydroxyl functional groups on the zinc anode, leading to a reduction in the number of active water molecules in the EDL. Third, BT molecules participate in the solvation structure to accomplish preferential reduction, which promotes the uniform deposition of Zn2+ ions by forming nitrogen‐containing SEI. Ultimately, the symmetric battery accomplishes 2700 stable cycles in BT‐3 electrolyte. More crucially, the corresponding Zn//MnO2 full battery (1 A g−1) is able to release a specific capacity of 117.2 mA h g−1 after 600 cycles.

Published: December 2024

AbstractTransition‐metal selenides hold great promise as advanced anode candidates for fast‐charging sodium‐ion batteries. However, an unstable solid electrolyte interphase (SEI) caused by their enormous volume expansion and strong catalytic action results in the continuous degradation of their sodium‐storage performance with cycling. Herein, a novel structure with carbon nanotubes bridging the adjacent layers of Mxene is constructed for host material, which can enrich the transport paths of electrons and ions within the electrode triggering a two‐electron reaction during the electrolyte decomposition, thereby tailoring an ultrathin and robust SEI rich in Na2O inorganic component. Thus the prepared anode demonstrates the improved initial Coulombic efficiency (87%) and cycling lifespan (442.9 mAh g−1 at 5 A g−1 after 1470 cycles). Meanwhile, it delivers a high‐rate capacity of 394.3 mAh g−1 at up to 20 A g−1, and accomplishes capacity retention above 90% as the current density transitions from 10 to 20 A g−1. Even when the current density increases to 5 A g−1 for 1470 cycles, the capacity retention is still higher than 90%. This study illustrates the feasibility of tailoring SEI components through electrode structure engineering and opens a new avenue to the controllable modulation of electrode‐electrolyte interfacial chemistry.

AbstractIn the pursuit of enhancing cancer treatment efficacy while minimizing side effects, near‐infrared (NIR) photothermal therapy (PTT) has emerged as a promising approach. By using photothermally active nanomaterials, PTT enables localized hyperthermia, effectively eliminating cancer cells with minimal invasiveness and toxicity. Among these nanomaterials, gold nanostars (AuNS) stand out due to their tunable plasmon resonance and efficient light absorption. This study addresses the challenge of measuring nanoscale temperatures during AuNS‐mediated PTT by employing X‐ray absorption spectroscopy (XAS) within 3D tumor spheroids. It also aims to investigate the heat generated at the nanoscale and the resultant biological damage observed at a larger scale, utilizing confocal microscopy to establish connections between AuNS heat generation, tissue damage, and their impacts on cellular structure. These nanoscale and microscale thermal effects have been compared with macroscopic values obtained from infrared thermography, as part of a multiscale thermal analysis. The findings underscore the efficacy of AuNS in enhancing PTT and provide insights into the spatial distribution of thermal effects within tumor tissues. This research advances the understanding of localized hyperthermia in cancer therapy and underscores the potential of AuNS‐based PTT for clinical applications.

Published: December 2024

AbstractIntroducing biological structures into materials design is expected to develop strong and tough structural materials. However, multiple interfaces are introduced simultaneously. They are always the weakest part of load transfer, becoming a critical vulnerability and failure‐prone area. Here, it is the first found that the chiton achieves superior mechanical properties just by incorporating a unique sinusoidal interlocking interface into cross‐lamellar architecture. These special interlocking interfaces make the chiton shell achieve damage delocalization and increase the resistance to crack initiation and propagation. Meanwhile, this “pre‐engineered” path significantly increases the travel path of the cracks and balances the strength and toughness under quasi‐static and impact loading. Inspired by this, a novel chiton‐inspired composite is proposed. Through coupling the cross‐lamellar structures and sinusoidal interlocking interfaces, its strength and toughness are increased by 88% and 107% under quasi‐static loading, as well as by 17.8% and 52.4% under impact loading, respectively. These unusual interfaces make up the weak point of cross‐lamellar structures and provide insights into the longer evolution of structural materials.

AbstractThe proton (H+) has been proved to be another important energy storage ion besides Zn2+ in aqueous zinc‐inorganic batteries with moderate electrolytes. H+ storage usually possesses better thermodynamics and reaction kinetics than Zn2+, and is found to be an important addition for Zn2+ storage. Thus, understanding, characterizing, and modulating H+ storage in inorganic cathode materials is particularly important. In this review, recent advances regarding the proton storage chemistry in aqueous zinc‐inorganic batteries with moderate electrolytes are systematically reviewed. First, the four proton storage reaction patterns of H+ insertion, H+/Zn2+ co‐insertion, H+‐dependent conversion, and H+‐dependent dissolution/deposition reaction are explicitly presented. Meanwhile, the proton storage processes of multi‐sites and multi‐steps, and the Hopping and Grotthuss proton transport mechanisms are carefully introduced. Second, the characterization techniques of proton storage are systematically classified into four types of electrochemical characterization techniques of batteries, structural characterization techniques of inorganic cathodes, pH characterization technique of electrolyte, and quantitative analysis technologies of H+ storage contribution. Third, the structural engineering of proton storage modulation is preliminarily refined to be interlayer engineering, doping engineering, defect engineering, composite engineering, and other engineering. Finally, the emerging challenges and perspectives about future directions of proton storage chemistry are proposed.

Published: December 2024

AbstractMechanoelectric energy conversion holds promise for energy conversion and transmission devices, yet conventional configurations rely on large‐area conductive materials in active regions, limiting architectural design for cutting‐edge devices. Here, a rational strategy is reported to create mechanical stimuli‐driven pseudo‐conductive (MSPC) channels entirely from dielectric materials, eliminating the need for electrodes in active regions. An in‐depth investigation of MSPC channel formation mechanism at dielectric interfaces is conducted, employing energy band analyses. Following the mechanical stimuli‐driven charging process, MSPC device effectively transmits electrical signals over 42 mm, achieving remarkable 512% enhancement compared to its pristine state. Control devices with non‐continuous dielectric configurations highlight the impact of heterojunction interfaces on MSPC channels. A resistor–capacitor charging test reveals up to 49% reduction in voltage change rate, indicating a substantial decrease in electrical impedance along the MSPC channel. Furthermore, MSPC devices demonstrate information transmission capabilities, such as sequences of bits or letters, utilizing solely dielectric configurations. This study paves the way to reduce conductive materials of wearable electronics, biomedical implants, and IoT technologies, overcoming significant challenges such as potential electrical shortages, design inflexibility, limited manufacturing scalability, and maintenance issues.

Published: December 2024

AbstractThis study introduces a rake‐shaped graphene nanostructure and investigates multiple Fano resonances and its sensing application by using finite‐difference time‐domain (FDTD) simulations method. Here, the dependence of structural parameters, Fermi levels, and the incidence angle and polarization of the input wave on optical transmission spectra is aimed at investigating. The results show that tunable multiple Fano resonances can be achieved in the rake‐shaped graphene nanostructure. In addition, the sensing characteristics based on the multi‐Fano resonance in rake‐shaped graphene nanostructure are also studied in the work. The research results show that the sensing sensitivity and figure of merit (FOM) can reach up to 2.1 THz/RIU and 3.3/RIU as a result of enhanced interaction between environmental substances and optical waves. These findings deepen the understanding of plasmonic resonances in graphene‐based metasurfaces and emphasize their significant potential in sensing applications.

AbstractThis study conducts a comprehensive first‐principles investigation of the IrMnAl Heusler alloy, highlighting its magnetic properties and assessing the effects of pressure‐induced phase shift. The limitation of Generalized Gradient Approximation (GGA) in accurately representing the magnetic behaviour of the compound is addressed by employing the GGA+U (Hubbard potential) approach, which more effectively captures the electronic features. At 5.6 GPa pressure, a novel structural phase transition from the cubic F 3 m, to the P 3 m space group is observed. The calculated Curie temperature, combined with the analysis of Mn‐Mn exchange interaction, sheds light on the weak ferromagnetism observed in the new phase of the compound.

AbstractProton‐conducting ceramic cells (PCCs), which include proton‐conducting ceramic fuel cells (PCFCs) and proton‐conducting ceramic electrolysis cells (PCECs), have attracted significant attention as high‐efficiency and eco‐friendly technologies for energy conversion. As compared with the impressive progress made in air electrode and electrolyte materials, fuel electrodes have received much less attention due to the faster reaction kinetics and lower polarization. Nevertheless, the design and optimization of fuel electrodes is also critical toward further electrochemical performance improvement, especially when the fuel is extended from hydrogen to ammonia and hydrocarbons for PCFCs. Herein, the recent research progress on the design strategies for fuel electrodes of PCCs is overviewed, including impregnation strategy, exsolution strategy, addition of catalytic layers, and optimization of electrode structure. Finally, perspectives on the challenges facing the development of advanced PCCs fuel electrodes are presented.
