AbstractZinc‐halogen batteries are promising for sustainable energy storage, offering high redox capacities at economical price points. However, they are hindered by issues such as the irreversibility caused by the dissolution of intermediates and the sluggish charge transfer, which limit their widespread adoption. Addressing these issues, bismuth‐iodide perovskite cathodes are employed as a halogen element enriched model system. These perovskite cathodes demonstrate considerable anion redox capacities. In a combined simulation and experimental study, it is uncovered that the (BAD)BiI4 (BAD+ denotes benzamidinium) cathode, greatly improves interactions with iodine species and boosts charge transfer capability compared to its (BA)BiI4 (BA+ denotes benzylaminium) counterpart. These enhancements can be attributed to the synergistic effects arising from stronger Bi−I···I halogen bonds and C═N─H···I hydrogen bonds. The (BAD)BiI4 cathode attains a reversible I−/I0 redox chemistry with 92% capacity retention after 30 000 cycles at a current density of 10 A g−1I, outperforming previously reported anion redox batteries. Additionally, the defect‐tolerant property and the I−/I0/I+ conversion of the (BAD)BiI4 are elucidated. The I5− forms a notably stronger bond with (BAD)BiI4 in comparison to I3−, which effectively mitigates polyiodide shuttling. These advantageous characteristics highlight the promise and adaptability of the developed perovskite cathodes for high‐performance anion redox chemistry.

AbstractPursuing power conversion efficiency (PCE) is the priority of developing organic solar cells (OSCs) based on low‐cost completely non‐fused ring acceptors. Herein, a donor/acceptor re‐intermixing strategy to enhance the photon capturing process, based on a previously established well‐stratified active layer morphology is reported. By adding 20 wt% PTQ10 (polymer donor) into the acceptor's precursor, the device PCE is increased to 16.03% from 15.11% of the D18/A4T‐16 control system, which is attributed to the additional charge generation interface and suppressed bimolecular recombination. On the contrary, using the equal ratio of PM6 leads to significant efficiency loss, indicating the importance of considering vertical distribution from the perspective of thermodynamics. Moreover, a cutting‐edge level of 17.21% efficiency for completely non‐fused ring acceptor systems is realized by altering the active layer to PBQx‐TF/TBT‐26 and PTQ11, via the identical processing strategy. This work thus presents attractive device engineering and solar cell performance, as well as in‐depth vertical morphology understanding.

AbstractTopical treatment offers a viable alternative for melanoma patients incompatible with surgical interventions. Herein, the study develops a skin‐penetrating peptide (SPP)‐based peptide drone (PD) for the transdermal delivery of antitumor proteins. To achieve cost‐effective therapeutics, Concanavalin A (ConA), which can be prepared through an extraction method, is loaded onto PDs. Compared with free proteins, ConA‐PD complexes (CPCs) demonstrate significantly greater skin permeation. Moreover, the CPCs exhibit potent anticancer activity both in vitro and in vivo, which substantially surpass the efficacy of the Aldara (imiquimod) cream. The CPC‐treated mouse skin remains clear, whereas Aldara cream induces side effects, including psoriasis‐like skin inflammation. The antimetastatic activity of the PD is identified as another advantage of CPC. The use of ConA as an anticancer agent has been significantly limited due to its high hepatotoxicity; however, the transdermal delivery strategy minimizes its hepatic absorption and, in turn, results in negligible hepatotoxicity. These results demonstrate the potential of the CPC as a novel therapeutic agent or an adjunct to other modalities for melanoma treatment, overcoming the limitations of existing materials while exhibiting superior efficacy.

AbstractUsing nuclear power to replace electricity generated from fossil fuels is an effective strategy to reduce global carbon dioxide emissions and also spurs the search for new sources of nuclear fuel. Extracting uranium from seawater has a significant reserve advantage, although its ultralow concentration presents substantial challenges. Here, inspired by the fractal structure of cardiac trabeculae on the inner surface of the heart, a uranium enrichment electrode with a superhydrophilic and uranium‐affinitive fractal surface is developed. This innovative design enhances rapid charge/ion transfer, ensures complete surface wetting, and provides numerous adsorption sites. By synergistically integrating the advantages of electric‐assisted processes and bioinspired microstructures predicated on chemical coordination principles, the electrode demonstrates a uranium adsorption capacity of 13.2 mg g−1 following a 7‐d exposure to natural seawater. This research not only demonstrates an effective strategy for the development of advanced uranium enrichment electrodes but also provides more possibilities for innovative approaches in sustainable energy technology.

AbstractThe emergence of the artificial intelligence urgently requires novel devices to handle massive data and bionic simulations. As one of new generation memory devices, memristor has great potential in information storage and brain‐like learning due to its merits, such as low energy consumption, high speed and etc. In addition, the randomness for the generation and breakage of the conducting filaments in the memristor can generate the true random numbers and realize the image encryption. In this work, the ITO/Cs2AgBiBr6/Al based devices exhibit prominent resistance variation characteristics and long‐term environmental stability (≥6 months). Additionally, the flexible PET/ITO/Cs2AgBiBr6/Al devices are assembled and measured resistance variation properties, which are adopt to realize the cryptographic processing of image information. The synaptic plasticity of the memristor is also verified, including paired pulse facilitation and spiking timing‐dependent plasticity. Finally, nociceptive responses are also simulated with the memristor via imposing different voltage. Nociceptive characteristics including “threshold,” “relaxation,” and “sensitization” have been successfully determined. The work provides possibility for lead‐free flexible perovskite memristors in information security and biomimicry.

AbstractThe utilization of salt concentration gradients as a renewable energy source represents a pivotal solution to the energy crisis. However, it is a persistent challenge to fabricate high‐performance ion permeable membranes with excellent ion permselectivity. In this work, hydrogen‐bonded organic framework (HOF) is in situ growth on anodic aluminum oxide (AAO) via chemical‐binding and solution‐processing strategy. The hydrogen bonding and π–π interactions forming the porous structure and the internal unprotonated carboxyl groups endow the HOF with superior cation selectivity and ion permeability. Furthermore, benefiting from the remarkable asymmetry of the prepared nanofluidic membrane arising from structure and charge of AAO and HOF, the HOF/AAO presents outstanding ion current rectification (ICR) characteristic, which can eliminate the ion concentration polarization (ICP) and power loss. Therefore, an impressive output power density with 500‐fold NaCl gradient is achieved as 75.2 W m−2 using the as‐prepared HOF/AAO, which is superior to most of reported membranes (7.0–40.0 W m−2). To show the critical role of HOF, 2D and 3D MOF with the same monomers are also synthesized, achieving decreased power densities of 36.2 and 58.3 W m−2 respectively. The present work provides a novel strategy to develop high‐performance nanofluidic ICR membranes for osmotic energy harvesting.

AbstractInterfacial defects and energy level mismatches between the perovskite and 2,2′,7,7′‐tetrakis[N,N‐di(4‐methoxyphenyl)amino]‐9,9′‐spirobifluorene (Spiro‐OMeTAD) layers heavily hinder charge transfer, limiting the efficiency and stability of n‐i‐p perovskite solar cells (PSCs). Herein, D‐type TPA, D‐A‐type TPA‐CN, and A‐D‐A‐type DTPA‐CN with triphenylamine units and different interfacial dipoles are designed as multifunctional interfacial layers for n‐i‐p PSCs. Among the three molecules, A‐D‐A‐type DTPA‐CN has the largest dipole moment, hole transporting capability, and hydrophobicity, and therefore the strongest passivation of interfacial defects and the best carrier extraction efficiency can be observed. As a result, the DTPA‐CN‐treated device achieves a champion power conversion efficiency (PCE) of 25.00%, as compared to the control device (22.78%). Moreover, the long‐term stability of the unencapsulated device is significantly improved. After 2,040 h of storage in a nitrogen glove box, the device maintains over 90% of its initial efficiency, while only 61% for the control device. The work indicates that simultaneous improvement of trap passivation and hole extraction is critical for achieving highly efficient and stable n‐i‐p PSCs.

Published: September 2024

AbstractSluggish kinetics of photoexcited charge carriers in photocatalysts, slow hole transfer in oxidation half‐reaction, and consequent fast charge recombination on photocatalyst surface are the Achilles' heel limiting the efficiency of photocatalytic hydrogen evolution (PHE). Herein, the effectiveness of covalent binding alternating D‐A‐D organic small molecules (triphenylamine as the donor unit and benzothiadiazole as the acceptor unit) to Znln2S4 (ZIS) nanosheets in the design and development of highly efficient PHE photocatalysts is demonstrated. The covalent grafting of D‐A‐D molecules broadens the photo‐responsive range of ZIS nanosheets, significantly increasing the density of photogenerated charge carriers. More importantly, D‐A‐D organic small molecules can efficiently extract surface photogenerated holes and suppress the recombination of surface photogenerated electron‐hole pairs, thus facilitating the rapid consumption of retained photogenerated electrons for proton reduction to generate H2 with fast kinetics. Consequently, the optimized PHE rate of the ZIS@DAD hybrid catalyst reaches 28.25 mmol g−1 h−1, a 4.2‐fold improvement over that of ZnIn2S4 nanosheets. The covalent integration of D‐A‐D molecules onto inorganic semiconductor photocatalysts represents a novel and highly efficient strategy for optimizing the overall PHE process. This approach provides a fertile new ground for creating efficient solar‐to‐hydrogen systems.

AbstractDue to their stable crystal framework, promising energy density, and structural versatility, layered 3d transition metal oxides have emerged as the preferred cathodes for lithium‐ion batteries (LIBs) and sodium‐ion batteries (SIBs). While extensive research has individually addressed the lithium and sodium 3d transition metal layered oxides, the differences and interconnections between the two types of materials have largely been overlooked. Effectively utilizing these summaries is essential for driving innovative structural designs and inspiring new insights into the structure‐property relationships. This review comprehensively bridges this gap by meticulously examining the disparities and links in the behavior of the layered oxides upon Li+ and Na+ storage and transfer. Key aspects, including atomic and electronic structure, phase transition mechanisms, charge compensation mechanisms and electrochemical kinetics, are carefully summarized. The implications of these aspects on the battery cycle life, energy density, and rate capability are thoroughly discussed. Additionally, by leveraging the unique characteristics of each oxide structure, this review explores the interconnection between lithium and sodium layered oxides in depth. Finally, a concise perspective on future targets and direction of 3d layered oxides is deduced and proposed.

AbstractCopper(I) thiocyanate (CuSCN) is a prominent wide‐bandgap p‐type semiconductor with desirable transparency and chemical robustness. Whereas intrinsic limitations, such as its relatively low Fermi level (EF) and modest electrical conductivity, have impeded its broader application in organic solar cells (OSCs). This study introduces a novel approach to modify the electronic properties of CuSCN by inducing copper vacancies through the use of specific solvent mixtures, thereby enhancing its suitability for OSCs. The effects of two solvent mixtures, methanol/ammonia (CH3OH/NH4OH) and dimethyl sulfoxide/N,N‐Dimethylformamide (DMSO/DMF) is have systematically investigated, on the CuSCN layer. The findings reveal that these solvent systems induce a higher concentration of copper vacancies within the CuSCN film, resulting in a significant reduction of the EF and a substantial increase in electrical conductivity. These modifications have led to the improved energy level alignment with the PM6:L8‐BO:BTP‐eC9 blended photoactive layers, culminating in a marked enhancement of the power‐conversion efficiencies of 19.10% for the DMSO/DMF processed CuSCN layer. Additionally, it has observed enhanced shelf/thermal stability and thickness tolerance of OSCs based on these CuSCN films. This work not only presents a novel strategy for modifying the performance characteristics of CuSCN but also underscores its potential to contribute to the advancement of photovoltaic technologies.

AbstractThe rapid development of the Internet of Things has led to numerous functional electronic devices, making it a significant challenge to provide power for these distributed devices. Triboelectric self‐power technology is ideal for smart devices due to its material diversity and high energy efficiency. However, traditional triboelectric materials have weak electrostatic induction due to their low dielectric constant. Additionally, the thermionic emission effect reduces their electric output in high temperatures, limiting their applications. This study designes a thermally robust aramid triboelectric material with a high dielectric constant through heat‐induced cross‐linking heterogeneous interface engineering. This novel material not only achieves high triboelectric output but also maintains high performance across a wide temperature range. The heat‐induced cross‐linking process enhances the interaction between aramid nanofibers and Al2O3 nanosheets, significantly improving the electrical performance, and flame retardance of the material, and the relative dielectric constant increases 16‐fold. The triboelectric nanogenerator constructed with this material achieves a power density of 3.97 W m−2, and maintains high triboelectric output at 260 °C. Finally, a self‐powered detection system collects high‐temperature gas energy and drives sensors is designed. This research presents a novel strategy for high‐performance triboelectric materials, showing significant potential for self‐powered devices.

AbstractMacroporous hydrogels have shown significant promise in biomedical applications, particularly regenerative medicine, due to their enhanced nutrient and waste permeability, improved cell permissibility, and minimal immunogenicity. However, traditional methods of generating porous hydrogels require secondary post‐processing steps or harmful reagents making simultaneous fabrication with bioactive factors and cells impossible. Therefore, a handheld printer is engineered for facile and continuous generation and deposition of hydrogel foams directly within the skin defect to form defect‐specific macroporous scaffolds. Within the handheld system, a temperature‐controlled microfluidic homogenizer is coupled with miniaturized liquid and air pumps to mix sterile air with gelatin methacryloyl (GelMA) at the desired ratio. An integrated photocrosslinking unit is then utilized to crosslink the printed foam in situ to form scaffolds with controlled porosity. The system is optimized to form reliable and uniform GelMA foams. The resulting foam scaffolds demonstrate mechanical properties with excellent flexibility making them suitable for wound healing applications. The results of in vitro cell culture on the scaffolds demonstrate significantly increased cellular activity compared to the solid hydrogel. The in vivo printed foam scaffolds enhanced the rate and quality of wound healing in mice with full‐thickness wound without the use of biological materials.

Published: September 2024

AbstractThe multifunctional responsive interfaces of liquid crystal (LC) and water are employed in fundamental research (colloidal assembly) and promising applications (sensing, release, and material synthesis). The stagnant LC systems, however, limit their use in continuous, automated applications. A microfluidic platform is reported where stable LC flow is maintained between aqueous interfaces. The LC‐water soft interface is defined by the preferential wetting of the two phases at the chemically heterogeneous microchannel interfaces. It is shown that the LC‐water interfaces are stable up to significant pressure differences across the interfaces and maintain responsive characteristics. The stability is in a range to cover the perpendicular and flow‐aligned regimes at low and high flow velocities, respectively, in co‐current or counter‐current flow configurations. The LC configuration at the vicinity of the aqueous interfaces is influenced by the shear induced by the bulk LC flow and by the contacting aqueous phases allowing modulation of the LC strain at the responsive interfaces. The simplicity of the construction and operation of the soft‐interface LC flow platform shows promise and meets the fundamental requirements for their integration into next‐generation autonomous platforms.

AbstractPaper finishing, in particular, coating paper with desired barrier functions is well‐developed as of today. However, due to large amounts of material and process energy as well as the use of non‐renewable resources for such coatings, common technologies are not sustainable. Given the increasing importance of paper in manifold applications, more sustainable routes with low‐energy processes as well as biogenic material alternatives are highly needed. To address this challenge, a solvent‐free and material‐efficient approach is proposed to bio‐based paper coatings by depositing chia oil‐based plasma polymers using a jet‐induced sliding discharge concept at atmospheric pressure. Depending on the amount of coating and the paper porosity, this treatment retards water absorption. Coating visualization is enabled through confocal laser scanning microscopy (CLSM) and scanning electron microscopy (SEM). Like chia oil, safflower oil, and olive oil show the ability to hydrophobize paper and the great potential within plasma polymerized vegetable oils to make the paper coating more sustainable.

Published: September 2024

AbstractPatterning of various surface properties, including roughness, wettability, adhesiveness, and mechanical properties, can markedly enhance the functionality of test systems. Thus, porous polymethacrylates prepared by polymerization‐induced phase separation (PIPS) represent a promising class of functional materials for the construction of miniaturized test systems. Different porosity, surface chemistry, and wettability are achieved in porous polymethacrylates with different precursor compositions. Nevertheless, only wettability microstructuring has been highlighted for these materials thus far. Here, the study presents a novel method for the direct and selective deposition of porous polymethacrylate films with different surface chemistry and porosity. The selective adhesion of omniphobic–omniphilic wettability patterns is used to facilitate the polymer pattern formation. The feasibility of patterning with different monomers and porogenic solvents is demonstrated. The topological study confirms the selective application of polymer structures with different thickness and roughness. The wettability characterization of the omniphobic material shows no significant changes caused by the operations performed. Thus, a new pattern with a greater difference in the wettability of the areas is produced in the process. Discontinuous dewetting of different liquids is performed. The use of poly(2‐hydroxyethyl methacrylate‐co‐ethylene dimethacrylate) (HEMA‐EDMA) modified patterns for precise living cell patterning is also demonstrated.
