AbstractContinuous monitoring of electrophysiological biosignals such as electrocardiogram (ECG) and bioimpedance (BioZ) rely on gel‐based electrodes and adhesive skin interfaces requiring active patient interaction inherently restricting chronic use. Current solutions aimed at addressing seamless, comfortable, and reliable recordings with dry electrodes use battery power and are limited to days of operation with clinical‐grade fidelity. Here, current limitations are overcome by uniting at‐distance wirelessly powered wearable electronics with carbon‐doped filament deposition modeling (FDM) printed dry electrodes that overcome impedance degradation by seamless integration into textile and biosymbiotic systems, allowing for high‐fidelity operation over indefinite timescales. These capabilities are demonstrated with ECG during work, activity, and sleep and BioZ recordings documenting gains in forearm training over weeks.

AbstractThe repair of hierarchical osteochondral defects requires complex gradient reconstruction at different levels, with continuous‐gradient mineralization being crucial. Strategies for achieving continuous‐gradient mineralization have rarely been reported. Here, a continuous‐gradient mineralized hydrogel is prepared using simple gravitational osmosis of a ≈2 nm amorphous calcium phosphate nanocluster (ACPC) suspension into composite organic frameworks for osteochondral regeneration. During gravitational infiltration, ACPC underwent gradual mineralization, resulting in the spontaneous formation of hydroxyapatite (HAP). The continuous‐gradient mineralized hydrogel aligned closely with the normal osteochondral structure, thereby effectively promoting repair of the cartilage and subchondral bone. In the cartilage layer, organic compounds improved the oxidative stress environment induced by injury and complemented the extracellular matrix of the cartilage. In the subchondral bone layer, HAP from the continuously mineralized hydrogel induced intracellular calcium accumulation in mesenchymal stem cells (MSCs), activating calcium/calmodulin‐dependent protein kinase 2 (CaMK2) and promoting osteogenic differentiation of MSCs through the calcium signaling pathway. Ultimately, compared with the nongradient hydrogel, this innovative gradient mineralization method exhibited significantly enhanced regeneration capabilities for osteochondral defects, as evidenced by metrics, such as bone volume/tissue volume (BV/TV), trabecular thickness (Tb.Th), and trabecular number (Tb.N). This holistic strategy provides hope in the field of osteochondral repair.

AbstractUltra‐wideband microwave absorbing (MA) materials covering the low‐frequency range (2–6 GHz) are highly desirable in civil and military fields. These materials can be fabricated based on the design of electromagnetic meta‐structure. Herein, a structural‐functional‐integrated ultra‐wideband SiO2 fiber reinforced cyanate ester (CE) MA composite based on an in situ‐grown graphene meta‐nanointerface layer (GrMI) (SiO2f/GrMI/CE) is reported. The relationship between the periodic structure of the graphene nano‐interface layer and the MA performance is discussed through experiments and simulations. The results show that SiO2f/GrMI/CE with a thickness of 8.78 mm exhibits an effective absorption bandwidth of 15.46 GHz (2.54–18 GHz). Remarkably, the reflection loss remains basically unchanged upon increasing the incident angle from 5° to 50°. Additionally, GrMI is an effective load‐bearing constituent, which increases the interfacial shear stress between SiO2f and the CE by ≈210% and contributes to achieving composites with an ultra‐high flexural strength (552.7 MPa). The excellent structural‐functional‐integrated performances ensure that the SiO2f/GrMI/CE composites are suitable for use as the skin materials of microwave stealth aircraft and other civil facilities. The work provides a novel pathway for the design of thinner, wider, lighter, and stronger MA components.

AbstractThe magnetic properties of van der Waals materials are profoundly influenced by structural defects. The layered antiferromagnet MnPS3 offers a unique opportunity to explore defect‐related magnetism, as Mn2+ vacancies can be generated by the intercalation of specific guest molecules. However, the effectiveness of this process in atomically thin flakes and the extent of the magnetic tunability remain unclear. Here, it is shown that the magnetic properties of MnPS3 can be tailored through the intercalation of different guest molecules. Notably, the insertion of four alkylammonium ions introduces different populations of Mn2+ vacancies, leading to a transition from the pristine antiferromagnetic state to more complex magnetic textures, including a ferrimagnetic state displaying a magnetic saturation of 1 µB per atom. Moreover, it is shown that the intercalation of few‐nm‐thick flakes also leads to the emergence of a ferrimagnetic response. This in‐flake intercalation, which can be monitored in real time using optical microscopy, can be interrupted before completion, generating lateral heterostructures between pristine and intercalated areas. This approach opens the way to the use of partial intercalation to define regions with distinct magnetic properties within a single flake.

Published: September 2024

AbstractThe emerging sub−1 nm nanowires (SNWs) have received tremendous attention given their intriguing properties and broad applications attributable to their ultrasmall feature size. However, applying SNWs in microstructure‐preserving macroscopic functional materials (e.g., aerogels) remains challenging because the solvents used for preparing SNWs are not compatible with conventional supercritical drying or freeze‐drying techniques. In this study, the fabrication of SNW aerogels (SNWAs) is pioneered by developing a nonpolar solvent‐based freeze‐casting strategy. Cyclohexane, a nonpolar solvent with a freezing point (6.5 °C) comparable to that of water, is selected as a reaction and drying medium to assemble various SNWs. The resulting self‐standing SNWAs display low density, excellent hydrophobicity and lipophilicity, and tunable luminescent color. This strategy not only introduces a new aggregation form of SNWs but also provides a creative perspective on synthesizing aerogel structures from sub−1 nm building blocks.

Published: September 2024

AbstractMetal‐to‐metal adhesives are vital across diverse sectors including automotive, aerospace, and industrial assembly. However, traditional adhesion detection methods are mainly based on the fracture mechanism, posing challenges for nondestructive detection. Here, a nondestructive method that leverages electrical signals to monitor the adhesion state of metal interfaces in real‐time is presented. The approach utilizes detectable adhesives (DA) synthesized from poly(ionic liquid) (PIL), which not only exhibit robust adhesion properties (4.9 MPa) but also function as ionic conductors. By correlating changes in capacitance and resistance with the adhesive state, the method allows for in situ monitoring of the curing process, prediction of adhesion strength, and early detection of potential failures. This dual‐sensing capability, combining electrical and mechanical aspects, enhances understanding of adhesive behavior in diverse conditions, presenting a fresh approach for digitally transforming adhesive technologies.

Authors: Andrew Lucas J. , Lizundia Erlantz , MacLachlan Mark J. 
Published: September 2024

AbstractTransient technology involves materials and devices that undergo controlled degradation after a reliable operation period. This groundbreaking strategy offers significant advantages over conventional devices based on non‐renewable materials by limiting environmental exposure to potentially hazardous components after disposal, and by increasing material circularity. As the most abundant naturally occurring polymer on Earth, cellulose is an attractive material for this purpose. Besides, (nano)celluloses are inherently biodegradable and have competitive mechanical, optical, thermal, and ionic conductivity properties that can be exploited to develop sustainable devices and avoid the end‐of‐life issues associated with conventional systems. Despite its potential, few efforts have been made to review current advances in cellulose‐based transient technology. Therefore, this review catalogs the state‐of‐the‐art developments in transient devices enabled by cellulosic materials. To provide a wide perspective, the various degradation mechanisms involved in cellulosic transient devices are introduced. The advanced capabilities of transient cellulosic systems in sensing, photonics, energy storage, electronics, and biomedicine are also highlighted. Current bottlenecks toward successful implementation are discussed, with material circularity and environmental impact metrics at the center. It is believed that this review will serve as a valuable resource for the proliferation of cellulose‐based transient technology and its implementation into fully integrated, circular, and environmentally sustainable devices.

AbstractConstruction of a robust artificial solid‐electrolyte interphase (SEI) layer has proposed an effective strategy to overcome the instability of the lithium (Li). However, existing artificial SEI layers inadequately controlled ion distribution, leading to dendritic growth and penetration. Furthermore, the environmental impact of the manufacturing process and materials of the artificial layer is often overlooked. In this work, a chemically and physically reinforced membrane (C‐Li@P) composed of the biocompatible Li+ coordinated carboxymethyl guar gum (CMGG) and polyacrylamide (PAM) polymers serves as an artificial SEI membrane for dendrite‐free Li. This membrane with hollow channels not only directs ion flux along the interspace of fibers, fostering uniform Li plating but also induces a desirable interface chemistry. Consequently, artificial SEI membrane‐covered Li exhibits stable electrochemical plating/stripping reactions, surpassing the cycle life of ≈750% of bare Li. It demonstrates exceptional capacity retention of ≈93.9%, ≈88.1%, and ≈79.18% in full cells paired with LiNi0.8Mn0.1Co0.1O2 (NMC811), LiNi0.6Mn0.2Co0.2O2 (NMC622) and S cathodes, respectively over 200 cycles at 1 C rate. Additionally, the water‐based green manufacturing and biodegradability of the membrane demonstrated the sustainable development and disposal of electrodes. This work provides a comprehensive framework for the design of an artificial layer chemically and physically regulating dendritic growth.

Published: September 2024

AbstractNanotopographic surfaces are a powerful tool for studying and controlling cell behavior. However, the fabrication of nanotopographic master patterns using conventional photolithography is expensive, which limits the range of designs that can be explored. In this study, a method is demonstrated for the photoreshaping of large‐area patterns of nanoridges. The original master pattern is created using conventional lithography, and an azopolymer replica is prepared using soft lithography. The manipulation of the nanoridges is achieved by projecting light with specific polarizations and exposure times, resulting in controllable widening, buckling, or removal of the ridges. The reprogrammed azopolymer master patterns can then be replicated, creating reproducible new nanotopographies that can be transferred into other materials using a molding procedure. Diffraction can be used for in situ monitoring of the reprogramming during exposure. Image‐analysis methods are used to characterize buckled ridges as a function of exposure time. The response of MCF10A epithelial cells are investigated to buckled nanoridges. A substantial impact of buckling on the dynamics and location of actin polymerization, as well as on the distribution and lengths of contiguous polymerized regions is also observed.

Published: September 2024

AbstractIn this study, the hierarchical assembly of DNA origami filaments (DOF) initiated by an autocatalytic DNA reaction network (DRN) is investigated. The so‐formed filaments are subsequently disassembled by toehold‐mediated strand displacement mechanisms. Using fluorescence resonance energy transfer, the kinetics of DOF growth after direct addition of fuel and compared it to the polymerization process triggered by the release of fuel from the DRN is monitored. Optimization of design and experimental conditions enabled to fine‐tune the kinetics of the two processes, ensuring that the release of fuel from the DRN outpaced the consumption of fuel by the downstream polymerization reaction. This resulted in a sustained and controlled DOF growth leading to micrometer‐long filament structures. Finally, although the presence of a toehold in the fuel strand reduced the efficiency of monomer association in the polymerization process, a 10‐fold excess of the anti‐fuel strand is efficient in dissociating the filament structures, permitting a potential reset for new reactions. The study shows that the kinetics of DNA origami filaments growth can be finely manipulated by a cascade of upstream reactions, suggesting alternative approaches for the creation of programmable DNA‐based nanomaterials that can sense and respond to more complex and distant events.

AbstractThe effective work‐function of metal electrode is one of the major factors to determine the threshold voltage of metal/oxide/semiconductor junction. In this work, it is demonstrated experimentally that the effective work‐function of the Aluminum (Al) electrode in Al/SiO2/n‐Si junction increases significantly by ≈1.04 eV with the graphene interlayer inserted at Al/SiO2 interface. The device‐physical analysis of solving Poisson equation analytically is provided when the flat‐band voltage is applied to the junction, supporting that the large tuning of Al effective work‐function may originate from the electric dipole layer formed by the off‐centric distribution of electron orbitals between Al and graphene layer. Our work suggests the feasibility of constructing the dual‐metal gate CMOS circuitry just by using Al electrodes with area‐specific underlying graphene interlayer.

Published: September 2024

AbstractThe development of high‐performance catalysts for formic acid (FA) dehydrogenation is of extreme significance to the successful production of hydrogen under ambient conditions. Despite some encouraging progress, their activity is still unsatisfied than needed. In this work, it is presented that Lewis acidic VOx sites engineered ultrafine PdAu nanoclusters (PdAu‐VOx) perform perfectly for hydrogen production from FA dehydrogenation. Strikingly, the best catalyst — PdAu‐VOx embed in amino‐functionalized hollow mesoporous support (PdAu‐VOx/NHMS) discloses an impressive initial turnover frequency of 14155 h−1 and a low activation energy of 31.2 kJ mol−1 without additives at room temperature, and maintains 100% selectivity and conversion in the tenth cycle reaction. Mechanistic investigations illustrate that VOx species can serve as the Lewis acid sites, which not only regulate the adsorption strength of reactant and intermediate on PdAu, but also reinforce the C─H bond activation within FA molecule, thereby promoting the reaction kinetics for efficient hydrogen production. This work thus provides a strategy for the development of new‐style heterogeneous catalysts with Lewis acid‐base sites applied to a variety of energy‐related catalytic reactions.

AbstractAimThe reconstruction methods after proximal gastrectomy (PG) are varied but not standardized. This study was performed to evaluate the short‐term clinical outcomes between double tract reconstruction (DTR) and double flap technique (DFT).MethodsWe retrospectively reviewed and collected data of patients who underwent DTR and DFT after laparoscopic proximal gastrectomy (LPG), respectively, between January 2020 and March 2023. Propensity score matching (PSM) was used to balance the baseline data of the two groups, then we compared their short‐term clinical outcomes.ResultsA total of 72 patients (48 and 24 patients in the DTR and DFT groups, respectively) were included. The anastomosis time was significantly longer in the DFT group than that in the DTR group (70.1 vs. 52.7 min, p < 0.001). DFT was associated with shorter times of gas‐passing, start of diet, and postoperative length of hospital stay (p < 0.001). There were no significant differences between the two groups in terms of early and late postoperative complications (p = 0.710, p = 1.000, respectively). DFT was superior to DTR in maintaining body weight (p < 0.001), total protein (p = 0.011) and albumin levels (p = 0.018). As for QOL, DTR showed better results in the meal‐related distress subscale (p < 0.001). However, DFT was superior to DTR in terms of reducing diarrhea, constipation, and dumping related symptoms (p < 0.05).ConclusionDouble flap technique emerged as a superior alternative to DTR in terms of facilitating early postoperative recovery, sustaining nutritional status, and improving QOL. DFT could potentially be the preferred reconstruction method following laparoscopic proximal gastrectomy.
Globalization of distributed parameter self‐optimizing control

Published: September 2024

AbstractNumerous nonlinear distributed parameter systems (DPSs) operate within an extensive range due to process uncertainties. Their spatial distribution characteristic, combined with nonlinearity and uncertainty, poses challenges in optimal operation under two‐step real‐time optimization (RTO) and economic model predictive control (EMPC). Both methods necessitate substantial computational power for prompt online reoptimization. Recent local distributed parameter self‐optimizing control (DPSOC) achieves optimality without repetitive optimization. However, its effectiveness is confined to a narrow range around a nominal operation. Here, globalized DPSOC is introduced to surmount the limitation of the local DPSOC. A global loss functional concerning controlled variables (CVs) is formulated using linear operators and Fubini's theorem. Minimizing the loss with a numerical optimization procedure yields CVs exhibiting global optimality. Maintaining these CVs at constants ensures such a process has a minimal average loss in a large operating space. The effectiveness of the proposed method is substantiated through a transport reaction simulation.

AbstractBackgroundAccurate conflict of interest (COI) information is essential for promoting transparency and trust in research. We aim to assess COI disclosure patterns in monoclonal antibodies (MABs) research for chronic rhinosinusitis with nasal polyposis (CRSwNP) using the Open Payments Database (OPD).MethodsStudies on FDA‐approved MABs for CRSwNP (dupilumab, omalizumab, mepolizumab) published between 2019 and 2021 with at least one US author were identified through PubMed. Industry‐reported payments from the manufacturers (Sanofi, Regeneron, Genentech, Novartis, and GlaxoSmithKline) between 2018 and 2021 in OPD's General Payments category were collected. Authors were cross‐checked against OPD metadata using a previously published ChatGPT‐based algorithm. Additionally, this novel algorithm analyzed COI statements for relevant author‒company specific disclosures, identifying disclosed and undisclosed payments made 3‒15 months prior to publication.ResultsA total of 214 unique authors from 76 studies were included. Of 30 articles that received at least one relevant payment, 21 (70%) were found to have an undisclosed COI, with a mean total undisclosed payment of $4890 and a median of $10,331. Fifty‐six authors had relevant OPD payments and 40 (71.4%) authors did not declare a potential COI. Interestingly, 158 authors had no relevant payments and 62 (39.2%) declared a potential COI. Author order was not significantly associated with potential under‐ or over‐disclosure.ConclusionThis study characterizes COI disclosure patterns in rhinosinusitis‐relevant MABs research using a novel automated approach. Given the discrepancy between disclosures and industry‐reported payments, our findings suggest a need for improved disclosure education and practices.
