The one-step methanol oxidation to dimethoxymethane (DMM) is a promising method for value-added chemical synthesis. However, vanadium cerium (VCe) catalysts commonly exhibit insufficient DMM selectivity in spite of its moderate high-temperature methanol conversion. In this work, titanium dioxide (TiO2) with relatively strong acidity was introduced into VCe catalyst to improve the catalysis performance of VCe. The results showed that the addition of TiO2 enhanced the oxidation reduction and surface acidity of the catalyst, and effectively improved the selectivity and yield of DMM. Furthermore, a scaled-up conceptual process for the one-step oxidation of methanol to DMM was explored, designed and economically evaluated based on the TiO2 modified catalysts. The entire conceptual process featured that multiple condensation-separation/absorption units offered a complete collection of the DMM. Through the optimization of the process, the generated products and unreacted methanol can be directly stripped from N2 and O2, and complete separation of DMM-methanol azeotrope was achieved with only one vacuum distillation unit. The entire process at what catalysis performance (methanol conversion, DMM selectivity, etc.) could bring profit was revealed and discussed. This study emphasizes the interaction between catalyst design, conceptual process design and economic evaluation, providing new ideas for the development of efficient industrial catalysts. © 2025

Measuring the thermal conductivity (κ) of water at extreme conditions is a challenging task and few experimental data are available. We predict κ for temperatures and pressures relevant to the conditions of the Earth mantle, between 1,000 and 2,000 K and up to 22 GPa. We employ close to equilibrium molecular dynamics simulations and a deep neural network potential fitted to density functional theory data. We then interpret our results by computing the equation of state of water on a fine grid of points and using a simple model for κ. We find that the thermal conductivity is weakly dependent on temperature and monotonically increases with pressure with an approximate square-root behavior. In addition we show how the increase of κ at high pressure, relative to ambient conditions, is related to the corresponding increase in the sound velocity. Although the relationships between the thermal conductivity, pressure and sound velocity established here are not rigorous, they are sufficiently accurate to allow for a robust estimate of the thermal conductivity of water in a broad range of temperatures and pressures, where experiments are still difficult to perform.

The lithium (Li) metal anode is essential for next generation high energy density rechargeable Li metal batteries. Although extensive studies have been performed to prolong the cycle life of Li metal batteries, the calendar life, which associates with chemical corrosion of Li metal in liquid electrolytes, has not been quantitatively understood. Here, by combing the Titration Gas Chromatography (TGC) method and Cryogenic Focused Ion Beam (Cryo-FIB), we established a quantitative relationship between the chemical corrosion rate and electrochemically deposited Li morphology in various liquid electrolyte systems. We identified that the corrosion rate is dominated by the porosity of the deposited Li. The larger the porosity of deposited Li has, the faster the corrosion rate will be. We further proposed strategies to mitigate the chemical corrosion on Li thus to extend the calendar life of Li metal batteries. By strictly controlling the stacking pressure during Li plating, Li deposits with ultra-low porosity can be achieved, suppressing the corrosion rate to 0.08 ± 0.16%/day compared with 1.71 ± 0.19%/day of the high-porosity Li.

Lithium (Li) metal anodes are essential for developing next-generation high-energy-density batteries. Numerous concerns on the potential safety hazards of the Li metal have been brought up before its massive application in commercialized battery packs. However, few investigations have been performed to systematically evaluate the reactivity of Li metal anode in full cell level. Here, differential scanning calorimetry (DSC) with in situ Fourier-transform infrared spectroscopy (FTIR) are used to quantitatively investigate the Li metal reactivity. Lithiated graphite (Li-Gr) and lithiated silicon (Li-Si) are also studied as the comparison samples. The reactivity of the plated Li when coupled with different electrolyte composition, morphology, and atmosphere is systematically studied. More importantly, the reactivity of Li metal full cell with different cathode materials (NMC622, LFP and LNMO) has been compared. It was found that all cell components, including electrolyte composition, Li morphology, the control of inactive Li accumulation and cathode stability, are essential in controlling the reactivity of the plated Li. After optimizing these conditions, the Li metal full cell shows no significant thermal reaction up to 400°C. This work identifies the key parameters in controlling the reactivity of the plated Li and may facilitate lithium metal battery design and manufacturing in the coming future. © 2023, CC BY.

This study investigates the activities of Ni-M (M = transition metals) bimetallic catalysts in Molten Carbonate Electrolysis Cells (MCEC) for hydrogen production via steam methane reforming (SMR) under electrolyte poisoning conditions by using the density functional theory (DFT) and experimental approach. Focusing on the cost-effective and high-activity Ni (211) catalyst, the study addresses the challenge of electrolyte (Li2CO3, K2CO3) evaporation leading to catalyst deactivation. Utilizing DFT, we examined partially electrolyte-poisoned Ni (211) slab models, particularly assessing potassium (K) atom effects. The study proposes bimetallic Ni-M surface alloy catalysts, such as Ni–V, demonstrating enhanced electrolyte poisoning resistance and superior catalytic activity compared to pure Ni. The findings highlight the potential of these catalysts to improve MCEC system efficiency, offering a more economical alternative to precious metal catalysts. © 2025 Hydrogen Energy Publications LLC

The rise in wearable electronics has witnessed the advancement of self-healable wires, which are capable of recovering mechanical and electrical properties upon structural damage. However, their highly fluctuating electrical resistances in the range of hundreds to thousands of ohms under dynamic conditions such as bending, pressing, stretching and tremoring may seriously degrade the precision and continuity of the resulting electronic devices, thus severely hindering their wearable applications. Here, we report a new family of self-healable wires with high strengths and stable electrical conductivities under dynamic conditions, inspired by mechanical–electrical coupling of the myelinated axon in nature. Our self-healable wire based on mechanical–electrical coupling between the structural and conductive components has significantly improved the electrical stability under dynamic scenarios, enabling precise monitoring of human health status and daily activities, even in the case of limb tremors from simulated Parkinson's *** mechanical–electrical coupling strategy opens a new avenue for the development of dynamically stable electrodes and devices toward real-world wearable applications.

To overcome Type 1 diabetes mellitus (T1DM), which can cause hyperglycemia due to diminished insulin secretion of β-cell function, islet transplantation has been developed with various strategies including pseudo-islet. However, conventional pseudo-islet formation techniques combining with other cells depend on natural cellular aggregation, which requires at least 5 days to form and even show segregation of distinct cell types, leading to diminished cell viability and function. Herein, we applied a subaqueous free-standing 3D cell culture (FS) device, which can reduce the spheroid formation time by trapped cell in nodes of acoustic standing wave. Briefly, Culturing with adipose-derived stem cells (ADSCs) to form heterotypic pseudo-islet (Hislet) in FS device dramatically reduced formation time less than one day. Hislet demonstrated enhancement of cell viability than conventional pseudo-islet formation method. Additionally, ADSCs combined Hislet proved strong secretion of various paracrine factors. Also results showed significantly increased angiogenesis effect and immunomodulation effect for various type of immune cells in Hislet compared to islet, which can enhance transplantation survival. Furthermore, Hislet validated glucose-regulating capacity and enhanced angiogenesis effect in vivo T1DM model. Throughout this study, we propose a novel strategy for forming Hislet that can overcome the limitations of conventional Islet and pseudo-islet for T1DM. © 2025 The Authors

In the present work, an aptasensor with dual binding sites based on Au NPs modified with self-polymerized polydopamine (PDA) and Fe-MOF is successfully constructed. In terms of standard electron transfer, the cyclic voltammetry (CV) analysis showcases a rate constant (ks) of 96.0 s-1, signifying an exceptional electron transfer rate of oxytetracycline at the sensor interface of Apt/Au@PDA@NH2-MIL-101(Fe)/GCE. Further deepening the investigation into electrochemical kinetics using chronoamperometry (CA), we investigated the electrocatalytic parameters (Kcat) of Au@PDA@NH2-MIL-101(Fe) in relation to oxytetracycline. The results divulged an impressive average Kcat value of 3.06×105 M-1 S-1. This evidence robustly suggests the superior electrocatalytic activity of Au@PDA@NH2-MIL-101(Fe) when it comes to oxytetracycline oxidation. A custom-designed portable rapid detection platform was developed, achieving detection limits of 6.88 nM under static water flow conditions and 5.56 nM under dynamic conditions. Remarkably, the self-polymerization of PDA on Au NPs not only refines their size but also boosts their interaction with biomolecules, thereby promising excellent biocompatibility. Moreover, the abundance of -COOH groups and unsaturated Fe3+ sites on the NH2-MIL-101(Fe) surface furnishes a considerable number of grafting sites for the aptamer. More importantly, the redox interplay between Au@PDA and NH2-MIL-101(Fe) accelerates electron movement, thus amplifying the electrochemical signal and the detection sensitivity for oxytetracycline. © 2024, The Authors.

P-type oxide semiconductors as a conducting channel layer have attracted huge attention owing to wide applications in electronic devices. In this study, multi-component oxide-semiconductor Cu1-2xMnxSnxO thin films with x = 0.05, 0.10, 0.15, 0.20, 0.25, 0.30, and 0.33 were successfully prepared on glass substrates, by using a solution process accompanied with a spin-coating technique. One obtained that, a phase transition between the CuO monoclinic structure and the rock salt structure was observed when leveling up the concentration of Mn and Sn, simultaneously to descending the concentration of Cu in the precursors. The crystallite size was found to decrease throughout the samples, with a minimum value of 9.8 nm towards the equimolar ratio. The scanning electron microscope confirmed further the downward tendency as mentioned above, and indicated an improvement in the film surfaces as well. According to the optical absorption measurement, the bandgap energy was determined to be in a range from 2.68 eV to 3.44 eV. Interestingly, the sheet resistance of Cu1-2xMnxSnxO films witnessed a sharp drop from 5.24 kΩ/sq of CuO to 0.034 kΩ/sq at the film with the molar ratio Cu:Mn:Sn being 34:33:33. © 2024, The Authors.
