    Reversible Iron Oxyfluoride (FeOF)‐Graphene Composites as Sustainable Cathodes for High Energy Density Lithium Batteries
    Wiley ; 2023

    Abstract: Two large barriers are impeding the wide implementation of electric vehicles, namely driving‐range and cost, primarily due to the low specific energy and high cost of mono‐valence cathodes used in lithium‐ion batteries. Iron is the ideal element for cathode materials considering its abundance, low cost and toxicity. However, the poor reversibility of (de)lithiation and low electronic conductivity prevent iron‐based high specific energy multi‐valence conversion cathodes from practical applications. In this work, a sustainable FeOF nanocomposite is developed with extraordinary performance. The specific capacity and energy reach 621 mAh g −1 and 1124 Wh kg −1 with more than 100 cycles, which triples the specific capacity, and doubles the specific energy of current mono‐valence intercalation LiCoO 2 . This is the result of an effective approach, combing the nanostructured FeOF with graphene, realized by making the (de)lithiation reversible by immobilizing FeOF nanoparticles and the discharge products over the graphene surface and providing the interparticle electric conduction. Importantly, it demonstrates that introducing small amount of graphene can create new materials with desired properties, opening a new avenue for altering the (de)lithiation process. Such extraordinary performance represents a significant breakthrough in developing sustainable conversion materials, eventually overcoming the driving range and cost barriers.

    Theoretical Investigation of the Oxygen Reduction Reaction over Platinum Catalysts Supported by Multi‐Edged Vertically Aligned Carbon Nanofiber for Electrocatalyst Preparation

    Abstract: Vertically aligned carbon nanofibers (VACNFs) are promising supports for oxygen reduction reaction (ORR) electrocatalysts in fuel cells. Although experimentally these catalytic systems have shown great potential, there is lack of molecular understanding of the catalytic sites and reaction mechanisms. This work investigated the origin of the ORR reactivities of the platinum catalysts on multi‐edged VACNFs (Pt/VACNF) using a multiscale modeling approach combining Density Functional Theory (DFT) and classical Molecular Dynamics (MD) simulations. Based on the ReaxFF potential, all nanoscale Pt particles (Pt 55 , P 100 , and Pt 147 ) are stabilized by the open edges located axially along the VACNF walls. The calculated first‐shell coordination numbers, , of surface Pt atoms are 6.63, 7.27, and 7.85, respectively, suggesting that the percentage of low coordination sites increases as the particle size decreases. The adsorption energies of OOH, O, and OH on Pt 55 were systematically probed using DFT calculations. These adsorption energies retain a linear correlation against the generalized coordination numbers ( ). For Pt nanoparticles supported on VACNF, we found that the OOH and OH bind stronger than on Pt (111) by 0.14 and 0.17 eV, respectively, which can hinder the ORR activity with lower limiting potential than Pt (111). Our theoretical prediction is in good agreement with the linear sweeping voltammetry that revealed a left shift of the half‐wave potential.

    Ultrathin Niobium Carbide MXenzyme for Remedying Hypertension by Antioxidative and Neuroprotective Actions
    Wiley ; 2023

    Abstract: Hypertension, as a leading risk factor for cardiovascular diseases, is associated with oxidative stress and impairment of endogenous antioxidant mechanisms, but there is still a tremendous knowledge gap between hypertension treatment and nanomedicines. Herein, we report a specific nanozyme based on ultrathin two‐dimensional (2D) niobium carbide (Nb 2 C) MXene, termed Nb 2 C MXenzyme, to fight against hypertension by achieving highly efficient reactive oxygen species elimination and inflammatory factors inhibition. The biocompatible Nb 2 C MXenzyme displays multiple enzyme‐mimicking activities, involving superoxide dismutase, catalase, glutathione peroxidase, and peroxidase, inducing cytoprotective effects by resisting oxidative stress, thereby alleviating inflammatory response and reducing blood pressure, which is systematically demonstrated in a stress‐induced hypertension rat model. This strategy not only opens new opportunities for nanozymes to treat hypertension but also expands the potential biomedical applications of 2D MXene nanosystems.

    Synergistic effects of fluid shear stress and adhesion morphology on the apoptosis and osteogenesis of mesenchymal stem cells
    Wiley ; 2022

    Abstract: Mechanical microenvironments, such as characteristics defining mechanical environments and fluid flow play an important role in steering the fate of mesenchymal stem cells (MSCs). However, the synergistic effect of adhesion morphology and fluid flow on the biological behavior of MSCs is seldom investigated. In this article, 0.5 or 0.8 Pa fluid shear stress (FSS) was applied to the MSCs on micropatterned substrates, and the apoptosis and osteogenic differentiation of MSCs were measured by double fluorescent staining. Results showed that the cellular adhesion patterns with low circularity and large area are beneficial to the osteogenic differentiation of individual MSCs. Meanwhile, FSS facilitated osteogenic differentiation of MSCs, as shown by the expression of alkaline phosphatase, osteocalcin, and collagen I. In addition, nuclear transfer of Yes‐associated protein, a transcriptional regulator in MSCs, was enhanced after being exposed to FSS. These results demonstrated the synergistic effects of FSS and adhesion morphology in directing the fate of MSCs, and these effects may be adopted to design bio‐functional substrates for cell transplantation in tissue engineering.

    SlMYC2 promotes SlLBD40 ‐mediated cell expansion in tomato fruit development
    Wiley ; 2024

    Abstract: As a plant‐specific transcription factor, lateral organ boundaries domain (LBD) protein was reported to regulate plant growth and stress response, but the functional research of subfamily II genes is limited. SlMYC2, a master regulator of Jasmonic acid response, has been found to exhibit high expression levels in fruit and has been implicated in the regulation of fruit ripening and resistance to Botrytis . However, its role in fruit expansion remains unknown. In this study, we present evidence that a subfamily II member of LBD, namely SlLBD40, collaborates with SlMYC2 in the regulation of fruit expansion. Overexpression of SlLBD40 significantly promoted fruit growth by promoting mesocarp cell expansion, while knockout of SlLBD40 showed the opposite result. Similarly, SlMYC2 knockout resulted in a significant decrease in cell expansion within the fruit. Genetic analysis indicated that SlLBD40‐mediated cell expansion depends on the expression of SlMYC2 . SlLBD40 bound to the promoter of SlEXPA5 , an expansin gene, but did not activate its expression directly. While, the co‐expression of SlMYC2 and SlLBD40 significantly stimulated the activation of SlEXPA5 , leading to an increase in fruit size. SlLBD40 interacted with SlMYC2 and enhanced the stability and abundance of SlMYC2. Furthermore, SlMYC2 directly targeted and activated the expression of SlLBD40 , which is essential for SlLBD40‐mediated fruit expansion. In summary, our research elucidates the role of the interaction between SlLBD40 and SlMYC2 in promoting cell expansion in tomato fruits, thus providing novel insights into the molecular genetics underlying fruit growth.

    Enhancing Methanol Oxidation Reaction with Platinum‐based Catalysts using a N‐Doped Three‐dimensional Graphitic Carbon Support

    Abstract: Nitrogen‐doped graphitic carbon materials have been widely used as a catalyst support in the methanol oxidation reaction (MOR). In this study, we report the role of three‐dimensionally architectured in‐situ N‐doped vertically aligned carbon nanofibers (VACNF) as a catalyst support for MOR in acidic and alkaline media. The abundant graphitic edge sites at the sidewall of N‐doped VACNF strongly anchor the deposited platinum group metal (PGM) catalysts and induce a partial electron transfer between the PGM catalysts and support. Density Functional Theory (DFT) calculations reveal that the strong metal‐support interaction substantially increases the adsorption energy of OH, particularly near the N‐doping sites, which helps to compete and remove the adsorbed intermediate species generated during MOR. The PGM catalysts on N‐doped VACNF support exhibits CO stripping at lower potentials comparing to the commercial Vulcan carbon support and presents an enhanced electrocatalytic performance and better durability for MOR.
