AbstractPersistent inflammation, characterized by the intense interplay of inflammatory chemokine secretion and immune cell infiltration, is a hallmark of many skin disorders including diabetic wounds and psoriasis with inadequate therapeutic interventions. Monocyte chemotactic protein‐1 (MCP‐1) is an inflammatory chemokine that plays a key role in recruiting and polarizing monocytes into pro‐inflammatory macrophages to establish a vicious cycle that worsens the inflamed tissue microenvironment. Here, the sponge‐like microneedles (HPMN) technology is described to alleviate inflammatory skin disorders. Heparin/4‐arm PEG‐NH2 network crosslinked onto microneedle surface spatially attracted and sequestered multiple inflammatory chemokines including MCP‐1. Enrichment of MCP‐1 on microneedles recruits and traps inflammatory monocytes within the porous structure of microneedles. Subsequent removal of microneedles not only depletes inflammatory chemokine, MCP‐1, but also its cellular source. As a result, HPMN treatment facilitates 47.1% smaller open wound area in mice and 27.2% shorter wound length in pigs. To demonstrate the versatility of the HPMN technology, it is also shown that combining the method with standard‐of‐care immunosuppressants reduces 45.1% epidermis thickening and attenuated immune cell influx in a mouse psoriasis model. Overall, the HPMN technology is a novel demonstration of employing inflammatory chemokine and cell extraction to treat a broad range of inflammatory skin disorders.

AbstractSilicon‐based anode has high theoretical capacity but suffers from poor electrical conductivity, large volume expansion, and unstable solid electrolyte interphase (SEI). Adding carbon nanotubes (CNTs) and carbon coatings are both very effective methods for addressing the above issues. The intrinsic sp2 covalent structure endows CNTs with excellent electrical conductivity, mechanical strength, and chemical stability, which makes them suitable for various energy storage applications, such as in lithium‐ion batteries (LIBs). Apart from the conductive network, CNTs can serve as current collectors, mechanical probes, and mechanical frameworks, and they have potential in the construction of next‐generation battery architectures. Carbon coatings are mixed ionic‐electronic conductors with good chemical stability that provide mechanical support and mitigate the volume expansion of Si‐based materials. This review outlines the advances in CNTs and carbon coatings as conductive networks in Si‐based anodes, as well as insights into their future development. It provides an in‐depth analysis of the percolation and mechanical mechanism of conductive networks, highlights the importance of flexible long‐range conductivity, and decouples the relationships between stress, interface stability, and electron/ion transfer.

AbstractSmall‐diameter vascular grafts having biomechanical properties similar to those of native arteries for the treatment of cardiovascular diseases are still elusive. Here, a hybrid extrusion printing and electrospinning technique is presented in which a layer of electrospun nanofibers is deposited over the printed gelatin‐methacryloyl (gelMA) constructs to improve the mechanical performance of gelMA grafts. Various blends of polycaprolactone (PCL) and poly(L‐lactide‐co‐ε‐caprolactone) (PLCL) polymer solutions are used to produce electrospun nanofibers. The variation of gelMA concentration is found to have a negligible role in the overall strength of the graft. It is shown that the burst pressure and tensile strength of the fiber‐reinforced gelMA constructs are comparable to those of native human arteries. Moreover, the compliance of grafts reinforced by 100% PCL and 75/25% PCL/PLCL nanofibers are found to be similar to human muscular arteries and elastic arteries, respectively. The cytocompatibility assessment shows that gelMA presents a bioactive surface for the endothelial cells to survive and grow. Also, PCL/PLCL electrospun nanofibers offer cellular metabolic activity in the same order of magnitude as observed in the control. Therefore, this hybrid technique opens up new possibilities for the fabrication of tubular constructs in tissue engineering.

AbstractImplantable electrical neurostimulators offer a promising avenue for treating neurological disorders. However, their dependency on a finite battery life limits their long‐term utility. Emerging transcutaneous ultrasound‐driven triboelectric nanogenerator (TENG) techniques provide solutions for converting external ultrasound waves into internal electricity. This study proposes an implantable ultrasound‐driven TENG (IU‐TENG) using polyether ether ketone (PEEK) for its exceptional stability inside a human body and acoustic impedance compatibility with human tissues. This IU‐TENG remarkably surpasses traditional titanium‐based encapsulation, resulting in a 99.94% efficiency in ultrasound transmission. In addition, PEEK contains numerous electron‐donating functional groups, making it suitable for TENG applications, particularly as a positive triboelectric layer. The device exhibits robust voltage outputs, reaching up to 11.50 and 8.75 V in water and in vivo, respectively, under body‐safe ultrasound intensities. Moreover, its ability to sustain a stable electrical output for over 300 min emphasizes the durability and mechanical resilience of PEEK. In vivo mouse models and ex vivo porcine tissue trials demonstrate the effectiveness of the IU‐TENG in nerve stimulation, showing its potential in medical treatments, enhancing the functionality and longevity of implantable medical devices.

AbstractAcoustofluidics has shown great potential in enabling on‐chip technologies for driving liquid flows and manipulating particles and cells for engineering, chemical, and biomedical applications. To introduce on‐demand liquid sample processing and micro/nano‐object manipulation functions to wearable and embeddable electronics, wireless acoustofluidic chips are highly desired. This paper presents wireless acoustofluidic chips to generate acoustic waves carrying sufficient energy and achieve key acoustofluidic functions, including arranging particles and cells, generating fluid streaming, and enriching in‐droplet particles. To enable these functions, the wireless acoustofluidic chips leverage mechanisms, including inductive coupling‐based wireless power transfer (WPT), frequency multiplexing‐based control of multiple acoustic waves, and the resultant acoustic radiation and drag forces. For validation, the wirelessly generated acoustic waves are measured using laser vibrometry when different materials (e.g., bone, tissue, and hand) are inserted between the WPT transmitter and receiver. Moreover, the wireless acoustofluidic chips successfully arrange nanoparticles into different patterns, align cells into parallel pearl chains, generate streaming, and enrich in‐droplet microparticles. This research is anticipated to facilitate the development of embeddable wireless on‐chip flow generators, wearable sensors with liquid sample processing functions, and implantable devices with flow generation and acoustic stimulation abilities for engineering, veterinary, and biomedical applications.

AbstractControlled dispersal of microfliers over large‐scale areas is crucial for both civil and agricultural applications. Until now, the study of flying soft actuators is limited by the complexity of the motion involved and with control when miniaturized to a micro‐scale. Drawing inspiration from the dynamics of dandelion seed spread, the study proposes a novel design for a flying soft actuator comprising Ti3C2Tx MXene and polyethylene (PE), which exhibits sensitive responses to various stimuli, including humidity, temperature, applied voltage, infrared light, and selective volatile organic compounds, leading to significant deformation at a rapid rate (up to 81.82°/s). An artificial seed capable of wind‐assisted flight is further fabricated by integrating a MXene/PE actuator with fiberglass. When exposed to light, the artificial seed opens its fiberglass pappus during descent, increasing resistance and thereby prolonging falling time by an impressive 83%. Moreover, the artificial seed demonstrates self‐sensing, i.e., changes in resistance caused by humidity and infrared light, which can be attributed to the absorption and desorption of water molecules within MXene layers. This enhanced falling time enables a wider dispersal range and precise control, making it highly promising for environmental monitoring, automated large‐scale sensor deployments, and large‐scale seed sowing for endangered plants species protection.

AbstractLaser‐induced graphene (LIG) is widely used to fabricate microsupercapacitors (MSCs) on various sustainable substrates, such as wood, cork, and lignin. However, the fabrication of MSCs, especially high energy density devices on paper, has rarely been reported. In this work, LIG electrodes are fabricated on wax‐coated paper, followed by electrochemical deposition of manganese oxide (MnO2). The obtained LIG/MnO2 supercapacitors exhibit a maximum areal capacitance of 86.9 mF cm−2, while a device with pristine LIG electrodes exhibit a capacitance of 9.1 mF cm−2, both measured at a current density of 0.1 mA cm−2. In addition, the supercapacitor exhibits good cycling stability, retaining 80% of its initial capacitance after 1000 charge/discharge cycles at a current density of 1 mA cm−2. Notably, the LIG/MnO2 supercapacitor exhibits an exceptionally high energy density of 7.3 µWh cm−2 at a power density of 38.8 µW cm−2. In summary, a simple, fast, scalable, reproducible, and energy‐efficient fabrication method is represented using electrochemical deposition of manganese oxide on paper‐based laser‐induced graphene, which are natural, abundant, and sustainable materials, paving the way for large‐scale production of environmentally friendly supercapacitors.

Authors: Bisquert Juan , Ilyassov Baurzhan , Tessler Nir 
Published: July 2024

AbstractThe switching response in organic electrochemical transistors (OECT) is a basic effect in which a transient current occurs in response to a voltage perturbation. This phenomenon has an important impact on different aspects of the application of OECT, such as the equilibration times, the hysteresis dependence on scan rates, and the synaptic properties for neuromorphic applications. Here we establish a model that unites vertical ion diffusion and horizontal electronic transport for the analysis of the time‐dependent current response of OECTs. We use a combination of tools consisting of a physical analytical model; advanced 2D drift‐diffusion simulation; and the experimental measurement of a poly(3‐hexylthiophene) (P3HT) OECT. We show the reduction of the general model to simple time‐dependent equations for the average ionic/hole concentration inside the organic film, which produces a Bernards‐Malliaras conservation equation coupled with a diffusion equation. We provide a basic classification of the transient response to a voltage pulse, and the correspondent hysteresis effects of the transfer curves. The shape of transients is basically related to the main control phenomenon, either the vertical diffusion of ions during doping and dedoping, or the equilibration of electronic current along the channel length.

AbstractEstablished in 1962, lithium–sulfur (Li–S) batteries boast a longer history than commonly utilized lithium–ion batteries counterparts such as LiCoO2 (LCO) and LiFePO4 (LFP) series, yet they have been slow to achieve commercialization. This delay, significantly impacting loading capacity and cycle life, stems from the long‐criticized low conductivity of the cathode and its byproducts, alongside challenges related to the shuttle effect, and volume expansion. Strategies to improve the electrochemical performance of Li–S batteries involve improving the conductivity of the sulfur cathode, employing an adamantane framework as the sulfur host, and incorporating catalysts to promote the transformation of lithium polysulfides (LiPSs). 2D MXene and its derived materials can achieve almost all of the above functions due to their numerous active sites, external groups, and ease of synthesis and modification. This review comprehensively summarizes the functionalization advantages of MXene‐based materials in Li–S batteries, including high‐speed ionic conduction, structural diversity, shuttle effect inhibition, dendrite suppression, and catalytic activity from fundamental principles to practical applications. The classification of usage methods is also discussed. Finally, leveraging the research progress of MXene, the potential and prospects for its novel application in the Li–S field are proposed.

AbstractOlfactory behaviors serve a wide variety of social functions in mammals. Odor may signal information about attributes of individuals important for mating and reproduction. Olfactory behaviors, such as scent‐marking, may also function as part of home range or resource defense strategies. We assessed the potential social and home range defense functions of olfactory behavior in a pair‐living and sexually monogamous primate, Azara's owl monkey (Aotus azarae), in the Argentinian Chaco. This is the most extensive investigation of owl monkey olfactory behaviors in the wild. Individuals regularly performed olfactory behaviors (group mean + SD = 1.3 + 0.5 per hour). The patterns were generally comparable to those observed in studies of captive owl monkeys, except that urine washing was the most common behavior in the wild, as opposed to scent‐marking and genital inspections. Most olfactory behaviors were performed by adults, and there were striking sex differences in genital inspections: almost all consisted of an adult male inspecting the paired adult female. These findings suggest that olfactory behaviors play an important role in signaling and coordinating reproduction among owl monkeys, particularly during periods of female conception and pregnancy. Additionally, our research indicates that these behaviors may also serve as a defense strategy for maintaining the core area of their home ranges. This study offers the first assessment of the role of olfactory behaviors in reproductive contexts and home range defense in pair‐living, monogamous platyrrhine primates.

AbstractA stable solid‐electrolyte interphase (SEI) is crucial for cycling reversibility of Na‐ion batteries by mitigating continuous side reactions. So far, the severe SEI dissolution leads to low Coulombic efficiency (CE) and short cycle life. Meanwhile, the quantified relationship between SEI components and their solubility remains unclear. In this work, we establish the direct correlation between SEI components and SEI solubility, and quantify that the solubility of organic‐rich SEI is 3.26 times of inorganic‐rich SEI. We further propose a feasible strategy to preform inorganic‐rich insoluble SEI and demonstrate a practical hard carbon (HC)||NaMn0.33Fe0.33Ni0.33O2 full cell in a commercial electrolyte of 1 M NaPF6 in propylene carbonate (PC) with 80.0 % capacity retention for 900 cycles, and achieve a record‐high average CE of 99.95 % for a practical Na‐ion full cell. This study provides an effective strategy of preforming insoluble SEI to suppress its dissolution towards highly reversible Na‐ion batteries.

AbstractUnderstanding the origin of surface reconstruction is crucial for developing highly efficient lattice oxygen oxidation mechanism (LOM) based spinel oxides. Traditionally, the reconstruction has been achieved through electrochemical procedures, such as cyclic voltammetry (CV), linear sweep voltammetry (LSV). In this work, we found that the surface reconstruction in LOM‐based CoFe0.25Al1.75O4 catalyst was an irreversible oxygen redox chemical reaction. And a lower oxygen vacancy formation energy (EO‐V) could benefit the combination of the activated lattice oxygen atoms with adsorbed water molecular. Motivated by this finding, a strategy of phase boundary construction from Co tetrahedral to octahedral was employed to decrease EO‐V in CoFe0.25Al1.75O4. The results showed that as the Co octahedral occupancy ratio rose to 64 %, a 3.5 nm‐thick reconstructed layer formed on the catalyst surface with a 158 mV decrease in overpotential. Further experiments indicated that the coexistence of tetrahedral‐octahedral (O−T) phase would result in lattice mismatch, promoting non‐bonding oxygen states and lowering EO‐V. Then more active lattice oxygen combined with H2O molecules to generate hydroxide ions (OH−), followed by soluble cation leaching, which enhanced the reconstruction process. This work provided new insights into the relationship between the intrinsic structure of pre‐catalysts and surface reconstruction in LOM‐based spinel electrocatalysts.

AbstractIonic liquids (ILs) are prized for their selective dissolution of carbon dioxide (CO2), leading to their widespread use in ionogel membranes for gas separation. Despite their advantages, creating sustainable ionogel membranes with high IL contents poses challenges due to limited mechanical strength, leakage risks, and poor recyclability. Herein, we leverage copolymerized and supramolecularly bound ILs to develop ionogel membranes with high mechanical strength, zero leakage, and excellent self‐healing and recycling capabilities. These membranes exhibit superior ideal selectivity for gas separation compared to other reported ionogel membranes, achieving a CO2/nitrogen selectivity of 61.7 and a CO2/methane selectivity of 24.6, coupled with an acceptable CO2 permeability of 186.4 Barrer. Additionally, these gas separation ionogel membranes can be upcycled into ionic skins for sensing applications, further enhancing their utility. This research outlines a strategic approach to molecularly engineer ionogel membranes, offering a promising pathway for developing sustainable, high‐performance materials for advanced gas separation technologies.

AbstractIn almost all electrochemical systems for electrochemiluminescence (ECL) analysis, electrodes are connected with an external power source, either directly or via wireless energy transfer circuit. That is inconvenient and makes some applications impossible. Herein, we use galvanized iron with two different metals as both power source and electrodes to achieve a self‐powered ECL and exploit ECL for the imaging of the corrosion of protective coating of widely used metal (e.g. galvanized iron) for the first time. The self‐powered ECL enables the visualization of the deterioration of galvanic coating on iron using a smartphone and the detection of ascorbic acid with a linear range of 0.5–100 μM and a limit of detection of 0.31 μM. The devices based on self‐powered approach do not require external power supply, thus effectively reducing their volume and cost. The self‐powered ECL holds great promise for metal corrosion imaging and analytical applications.

SummaryPeripheral neuropathy is a well‐described side effect of certain chemotherapeutic agents, including taxanes, and often improves in the weeks following treatment. The recurrence of motor and sensory neuropathies after anaesthesia has not yet been described to our knowledge. We present a case of transient recurrence of chemotherapy‐induced peripheral neuropathy following general anaesthesia. Although an exact mechanism has not yet been described and is likely multifactorial in nature, anaesthetists should be prepared to address this phenomenon in the growing population of patients on chemotherapeutic agents.
