Published: August 2013

Aim Repeated needle punctures of arteriovenous hemodialysis grafts can lead to the development of pseudoaneurysms. As they enlarge, graft pseudoaneurysms are associated with significant morbidity and require treatment. We present our single-center experience using stent grafts in selected patients to exclude symptomatic hemodialysis graft pseudoaneurysms. Materials and Methods Between March 2007 and December 2010, 11 consecutive patients (7 men and 4 women, mean age 57 years) underwent percutaneous endovascular repair of symptomatic hemodialysis access graft pseudoaneurysms. Indications for treatment were rapidly enlarging pseudoaneurysm in 5 patients, high venous pressures, limb edema and pseudoaneurysm in 3, skin breakdown over the pseudoaneurysm site in 2 and acute rupture and bleeding in 1 patient. No patient was lost to follow-up. Results Technical success across the 11 patients was 90.9%. The patient who presented with rupture required ligation of the access due to continuous bleeding after stent graft insertion. Balloon angioplasty of a separate hemodynamically significant stenosis at the time of stent graft insertion was performed in 7 of 11 (63.6%) patients. The primary access patency rates were 72.7% (95% CI of 0.390-0.939) at 3 months and 36.4% (95% CI 0.109-0.692) at 6 months. Secondary access patency rates were 72.7% at 6 months (95% CI 0.233-0.832). There were no procedure-related complications. Mean follow-up was 9 months (range 2-29 months). Conclusions Endovascular treatment of symptomatic hemodialysis graft pseudoaneurysms is safe and effective with similar patency rates to surgical approaches. Importantly, this approach allows aggressive management of associated access circuit stenoses at the same time and avoids interval tunneled dialysis line insertion.

AbstractWhen low muscle mass and impaired strength and physical function coexist with excess adiposity, it is termed sarcopenic obesity (SO). Handgrip strength (HGS) is a predictor of disability and mortality. Asymmetry in HGS, particularly ≥ 10% strength differences between hands, may indicate neuromuscular dysfunction observable prior to declines in maximal strength are detectedand therefore could be incorporated to identify those at risk of physical limitations and SO. This study compares HGS values and asymmetry in older adults with excess adiposity and evaluates their relationships with physical function. Baseline data from two previous pilot weight loss studies in 85 older adults with body mass index values ≥ 30 kg m−2 are included with measures of body composition, walking speed, and chair stand ability. Sixty‐three participants met the criteria for SO. HGS correlated to gait speed (r = 0.22), distance walked (r = 0.40), chair stand time for 5 repetitions (r = 0.42) and during 30 s (r = 0.31). HGS asymmetry is only correlated to gait speed (r = 0.31) and there are no differences in physical function between those with and without asymmetry. Maximal HGS tests should continue to be used to screen for functional decline and disability.

AbstractAs the efficiency of single‐junction organic solar cells (OSCs) is about to break 20%, more research effort is needed to achieve long‐term device stability for commercialization. The complex active layer microstructure of bulk‐heterojunctions challenges the degradation mechanism study, especially for the morphological changes under thermal stress. In this work, this issue can be overcome by employing planar‐heterojunction (PHJ) OSCs with well‐defined bi‐layered structures, which enables effective control of the microstructure of polymer donor layers. The evolution of photovoltaic parameters of the PHJ OSCs under thermal stress is specifically revealed, which is strongly related to the inter diffusion of small molecular acceptors into the amorphous phases of the polymer donors. Increasing the crystallinity of polymer donors can effectively stabilize the donor/acceptor interfaces and the photovoltaic performances. The work puts forward effective strategies to improve the morphological stability of OSCs and alternative approaches for mechanistic studies on the thermal stability of OSCs.

AbstractAccurate and rapid quantification of cytokines in biofluids is crucial for early disease diagnosis, management, and prevention. However, it still remains challenging for existing sensors due to the broad dynamic range of cytokines and high interference from sample matrices. To overcome these challenges, electrochemical (EC) and field‐effect transistor (FET) dual‐mode biosensing is integrated on an extended‐gate carbon nanotube field‐effect transistor. This biosensor chip effectively eliminates direct contact between the device and the solution and employs independent signal readouts based on two distinct response mechanisms, thereby circumventing the limitations associated with conventional transistor biosensors. Selective detection of cytokine (e.g., Interferon‐γ, IFN‐γ) is achieved by the FET sensing mode (0.1 to 4000 pg mL−1, with a limit of detection of 24.1 fg mL−1) and the EC sensing mode (0.4–2000 ng mL−1) at different concentration range. The feasibility of real sample analysis using the EC‐FET dual‐mode biosensor is confirmed by detecting salivary levels of IFN‐γ. The combination of EC and FET sensing modes not only provides high sensitivity and a wide response range (seven orders of magnitude) to accommodate various biological samples but also improves the reliability of detection results, which shows promising applications in biological analysis and early disease diagnosis.

AbstractEffective integration of multiple active moieties and strategic engineering of coordinated interfacial junctions are crucial for optimizing the reaction kinetics and intrinsic activities of heterogeneous electrocatalysts. Herein, a simple integrated heterostructure of biphasic Co0.7Fe0.3/Fe3C embedded on in situ grown N‐doped carbon sheets is constructed. Rationally designed CoFe/Fe3C‐T2 owns more accessible active sites and interfacial junction effects, cooperatively boosting the electron and mass transfer, needed for multifunctional electrocatalysis. Leveraging the synergistic effect of dual active sites, CoFe/Fe3C‐T2 demonstrates outstanding oxygen electrocatalytic activity in alkaline medium with an ultra‐low potential gap of 0.58 V, surpassing the recently available state‐of‐the‐art catalysts. Moreover, CoFe/Fe3C‐T2 air‐electrode achieves a high peak power density of 249 mW cm−2, a large specific capacity of 808 mAh g−1 and excellent cycling stability for aqueous Zn‐air batteries. Remarkably, the solid‐state flexible ZAB also exhibits satisfactory performance, showcasing an open‐circuit voltage of 1.43 V and a peak power density of 66 mW cm−2. These outstanding results push this catalyst to the top of the list of non‐noble metal‐based electrode materials. This work offers a viable method for using the active‐site‐uniting strategy to create double‐active‐site catalysts, which may find real‐time applications in energy conversion/storage devices.

Published: July 2024

AbstractUnderstanding the structure and function of bioelectric materials is challenging due to the complex nature of biomaterials and a lack of appropriate tools. The precisely defined structures and genetic tunability of viruses provide an excellent model system to investigate bioelectrical behavior in biomaterials. This study presents the molecular mechanisms of piezoelectricity in the M13 bacteriophage (phage) under various mechanical stresses for bio‐piezoelectric generation. A computational approach is used to calculate the piezoelectric tensors of the M13 phage and quantify its direction‐dependent dipole moments. By computationally designing negatively charged residues on the phage surface, the surface charge density is enhanced to 16.7 µC cm−2. Using genetic engineering, phages are experimentally designed with different charges and tail structures to create model phage nanostructures, including individual phages, vertically standing phage films, and horizontally aligned phage films. Their vertical, horizontal, and shear‐mode piezoelectric properties are then measured using scanning probe microscopy techniques. The resulting phage‐based piezoelectric energy generators exhibit an effective piezoelectric coefficient of 15.4 pm V−1 and a power density of 4.2 µW cm−2. This phage‐based bioengineering approach provides a versatile platform for investigating fundamental mechanisms of bioelectricity and designing bioelectric materials for applications in energy harvesting, biomemory, and biosensors.

AbstractThe development of efficient and long‐term stable electrodes for hydrogen evolution reaction (HER) in seawater is highly desirable for hydrogen generation but remains challenging. In this work, a highly active CrOx@Ni2P‐Ni5P4/NF electrode is developed and investigated its dynamic reconstruction for HER in neutral electrolytes. The combination of in situ Raman spectra and electrochemical measurements revealed the dynamic surface reconstruction of the catalyst during HER. The CrOx modification not only effectively facilitates water dissociation but also stabilizes the structure post‐reconstruction, enabling rapid and stable hydrogen generation in neutral media. Remarkably, CrOx@Ni2P‐Ni5P4/NF exhibits overpotentials of 109 and 263 mV at current densities of 10 and 100 mA cm−2 in 1 m PBS, respectively. Concurrently, it exhibits stable operation for 500 h in 1 m PBS and 140 h in natural seawater at current densities of 50 and 100 mA cm−2, respectively. The proposed catalytic electrode and the mechanistic insights present a significant stride toward the realization of metal phosphides for direct seawater splitting.

AbstractAqueous potassium‐ion batteries with inherent safety, high abundance, and competitive hydrated ion‐radius point to future availability in energy storage. However, the extensively studied electrodes (metal‐oxides, Prussian‐blue‐analogues, etc.) typically suffer from undesirable capacities and sluggish kinetics owing to overwhelming ion diffusion barriers. Herein, for the first time, the metal chalcogenide bismuth selenide reinforced by iodine‐doping (I‐Bi2Se3) is implemented for high‐performance aqueous potassium‐ion storage. The co‐intercalation mechanism of potassium‐ion with proton in I‐Bi2Se3 is entirely revealed by operando synchrotron X‐ray diffraction and substantial ex‐situ analysis, and the excellent interlayer diffusion kinetics in the high‐conductive host are further enhanced by iodine‐doping, as proposed by theoretic calculations. Therefore, the resulting high diffusion coefficient and low interfacial transfer resistance endow I‐Bi2Se3 with superior rate performance (109.2 mAh g−1 at 10 A g−1) and cycling stability (91% capacity retention after 1200 cycles). Employing in hybrid‐ion batteries matching zinc metal, the highest reversible aqueous potassium‐ion storage to date of 316.8 mAh g−1 is demonstrated, permitting the establishment of reliable performance pouch cells. The promising aqueous potassium intercalation chemistry built in the improved metal chalcogenide is proven to be extendable to other hybrid‐ion devices, offering novel mechanistic insights and material practices for aqueous energy storage.

AbstractHydrogel‐based injectable drug delivery systems provide temporally and spatially controlled drug release with reduced adverse effects on healthy tissues. Therefore, they represent a promising therapeutic option for unresectable solid tumor entities. In this study, a peptide‐starPEG/hyaluronic acid‐based physical hydrogel is modified with ferrocene to provide a programmable drug release orchestrated by matrix‐drug interaction and local reactive oxygen species (ROS). The injectable ROS‐responsive hydrogel (hiROSponse) exhibits adequate biocompatibility and biodegradability, which are important for clinical applications. HiROSponse is loaded with the two cytostatic drugs (hiROSponsedox/ptx) doxorubicin (dox) and paclitaxel (ptx). Dox is a hydrophilic compound and its release is mainly controlled by Fickian diffusion, while the hydrophobic interactions between ptx and ferrocene can control its release and thus be regulated by the oxidation of ferrocene to the more hydrophilic state of ferrocenium. In a syngeneic malignant melanoma‐bearing mouse model, hiROSponsedox/ptx slows tumor growth without causing adverse side effects and doubles the relative survival probability. Programmable release is further demonstrated in a tumor model with a low physiological ROS level, where dox release, low dose local irradiation, and the resulting ROS‐triggered ptx release lead to tumor growth inhibition and increased survival.

AbstractMild photothermal therapy (PTT) has attracted attention for effectively avoiding the severe side effects associated with high‐temperature tumor ablation. However, its progress is hindered by the limited availability of high‐performance photothermal agents (PTAs) and the thermoresistance of cancer cells induced by heat shock reactions. Herein, this work proposes a new strategy to expand the library of high‐performance organic small‐molecule PTAs and utilize it to construct a multifunctional nano‐theranostic platform. By incorporating additional acceptors and appropriate π‐bridges, a diketopyrrolopyrrole‐based dye BDB is developed, which exhibits strong absorption and bright fluorescence emission in the near‐infrared (NIR) region. Subsequently, BDB is co‐coated with the heat shock protein (HSP) inhibitor tanespimycin (17‐AAG) using the functional amphiphilic polymers DSPE‐Hyd‐PEG2000‐cRGD to form an all‐in‐one nanoplatform BAG NPs. As a result, BAG NPs can precisely target tumor tissue, guide the treatment process in real‐time through NIR‐II fluorescence/photoacoustic/photothermal imaging, and release 17‐AAG on demand to enhance mild PTT. Additionally, the mild PTT has been demonstrated to induce immunogenic cell death (ICD) and activate a systemic anti‐tumor immune response, thereby suppressing both primary and distant tumors. Overall, this study presents a multifunctional nanoplatform designed for precise mild PTT combined with immunotherapy for effective tumor treatment.

AbstractFacing the resource and environmental pressures brought by the retiring wave of lithium‐ion batteries (LIBs), direct recycling methods are considered to be the next generation's solution. However, the contradiction between limited battery life and the demand for rapidly iterating technology forces the direct recovery paradigm to shift toward “direct upcycling.” Herein, a closed‐loop direct upcycling strategy that converts waste current collector debris into dopants is proposed, and a highly inclusive eutectic molten salt system is utilized to repair structural defects in degraded polycrystalline LiNi0.83Co0.12Mn0.05O2 cathodes while achieving single‐crystallization transformation and introducing Al/Cu dual‐doping. Upcycled materials can effectively overcome the two key challenges at high voltages: strain accumulation and lattice oxygen evolution. It exhibits comprehensive electrochemical performance far superior to commercial materials at 4.6 V, especially its fast charging capability at 15 C, and an impressive 91.1% capacity retention after 200 cycles in a 1.2 Ah pouch cell. Importantly, this approach demonstrates broad applicability to various spent layered cathodes, particularly showcasing its value in the recycling of mixed spent cathodes. This work effectively bridges the gap between waste management and material performance enhancement, offering a sustainable path for the recycling of spent LIBs and the production of next‐generation high‐voltage cathodes.

AbstractSwitchable adhesion, a phenomenon characterized by the ability to transition between attachment and detachment states under external stimuli, has recently gained popularity in various advanced devices. The realization of the desired functionalities on such surfaces relies on intricate interfacial designs. A general understanding of the commonalities and distinctions among these designs can foster the development of refined switchable adhesion interfaces (SAIs). To address this, this review first examines adhesion interfaces by focusing on the fundamental interactions at the atomic/molecular level, adhesion models, and their correlation with the diverse forces/bonds that dominate the adhesion behaviors. The latest progress in SAIs based on various forces/bonds, including electrostatic force, van der Waals force, capillary force, chemical bond, and suction force, is then discussed with regard to their specific design strategies, such as structures, components, and triggers. Additionally, an extensive overview of the broad applications of SAIs in fields ranging from space to biomedicine is provided, along with an exploration of the prevailing challenges and potential opportunities. With the rapid progress that has been made in state‐of‐the‐art mechanisms and design strategies, SAIs are expected to undergo booming development in the foreseeable future.

AbstractStructural supercapacitors that simultaneously bear mechanical loads and store electrical energy have exciting potential for enhancing the efficiency of various mobile systems. However, a significant hurdle in developing practical structural supercapacitors is the inherent trade‐off between their mechanical properties and electrochemical capabilities, particularly within their electrolytes. This study demonstrates a tough polymer electrolyte with enhanced multifunctionality made through the controlled hydration of a solid polymer electrolyte with poly(lactic acid) (PLA) and lithium salts. Characterization via differential scanning calorimetry, X‐ray diffraction, and Fourier transform infrared spectroscopy confirms the consistent amorphous solid solution phase in varying salt concentrations, whether dried or hydrated. Electrochemical tests and tensile tests are performed to evaluate the ionic conductivity and mechanical properties of these electrolytes. The results indicate that the strategic incorporation of water in the polymer electrolyte significantly enhances the ionic conductivity while preserving its mechanical properties. A specific composition demonstrated a remarkable increase in ionic conductivity (3.11 µS cm−1) coupled with superior toughness (15.4 MJ m−3), significantly surpassing the base polymer. These findings open new horizons for integrating electrochemical functionality into structural polymers without compromising their mechanical properties. Additionally, the paper reports the successful fabrication and testing of structural supercapacitor prototypes combining carbon fibers with fabricated electrolytes, showcasing their potential for diverse applications.

AbstractThe ongoing advancements and growing adoption of infrared detection technology have spurred a tremendous amount of interest in thermal camouflage technology. Various approaches are employed to develop infrared camouflage materials capable of manipulating emissivity or surface temperature. However, the range of thermal radiation regulation implemented by these materials is still somewhat limited. In this paper, a combined emissivity and temperature regulation strategy that integrates a thermoelectric device (TED) and a thermochromic structure is proposed. By utilizing this strategy, it becomes possible to simultaneously control the surface temperature and the emissivity without needing additional complex excitation. As a concept demonstration, large tunabilities of 0.38 for long‐wave infrared (8–14 µm) emittance and 87 °C for surface temperature are observed, resulting in a prominent tunability of the thermal radiation temperature that is 15.4 °C greater than that of a conventional TED with constant emissivity. This work aims to introduce a new design paradigm for future thermal radiation management and camouflage techniques.
