Abstract Biomass-derived hard carbon has gradually become an important component of sodium-ion batteries’ anodes. In this work, Setaria viridis, a widely distributed plant, was employed as a precursor to synthesize hard carbon anodes for sodium-ion batteries. However, the hard carbon derived from raw precursors contains substantial impurities, which limit the performance of the obtained hard carbon. With different chemical etching processes, the content of impurities in the resultants was reduced to varying degrees. The optimized hard carbon anode delivered a reversible capacity of 198 mAh g⁻¹ at a current density of 0.04 A g⁻¹. This work shows the More > Graphic Abstract

Abstract Solid oxide fuel cells (SOFCs) have attracted considerable attention for their high efficiency, environmental advantages, and versatility in fuel sources. Research has shown that optimizing the structure of SOFCs can lead to significant performance improvements. Additive manufacturing (AM) has emerged as a promising technology for geometrical optimization of SOFCs, owing to its capability to create complex and programmable structures. However, fabricating three-dimensional electrode structures with fine, highly resolved features remains a significant challenge. Herein, a vat photopolymerization (VPP) 3D printing process was developed for fabricating the Nickel Oxide-Yttria Stabilized Zirconia (NiO-YSZ) anode structure of SOFC.… More >

Abstract Silicon (Si) anodes are promising candidates for lithium-ion batteries due to their high theoretical capacity and low operating voltage. However, the significant volume expansion that occurs during lithiation presents challenges, including material degradation and decreased cycle life. This study employs an electrochemical-mechanical-thermal coupled finite element model, supported by experimental validation, to investigate the impact of lithiation-induced deformation on the energy dissipation of Si anodes. We quantitatively investigate the effects of several key design parameters—C-rate, Si layer thickness, and lithiation depth—on energy losses resulting from various mechanisms, such as mechanical energy loss, polarization, and joule heating.… More >

Abstract With society's rapid progress, there is an increasing need for electricity among individuals, but the prevailing source of electricity is still mainly obtained through the burning of nonrenewable fossil fuels, which are not renewable and pose serious environmental hazards. Lithium-ion batteries are used widely for excellent rechargeable capabilities and high energy density. Recently, researchers have become increasingly interested in transition metal sulfides owing to their cost-effectiveness and remarkable specific capacity. However, their commercialization has been hindered by the expansion of material volume and low electrical conductivity during charging and discharging. We have successfully designed and More >

Abstract The synthesis and characterization of reduced graphene oxide/cadmium sulfide (rGO/CdS) are the primary topics covered in this paper. The construction of a photoanode in dyesensitized solar cells (DSSCs) using synthetic materials is subsequently proposed. Here, graphene oxide (GO) was synthesized using the Hummer's method, and green tea leaves were employed to reduce GO. The rGO/CdS nanocomposites were prepared using a hydrothermal method. A photoanode was fabricated from the as-prepared rGO/CdS nanocomposite paste using doctor blade deposition techniques.
The performance of the fabricated DSSCs was evaluated using current density-voltage (JV) curves. Transmission electron microscopy (TEM), X-ray… More >

Abstract Objective: The study aimed to explore the protective mechanism of Ganoderic acid A (GAA) in renal fibrosis and to verify that GAA can ameliorate renal fibrosis by regulating the Niemann-pick C1-like 1 (NPC1L1) gene. Methods: Transforming growth factor beta1 (TGF-β1) was used to treat Human Kidney-2 (HK-2) cells to establish a renal fibrosis model. The differentially expressed genes in the control (CTRL) group, TGF-β1 group, and TGF-β1 + GAA group were screened via transcriptome sequencing technology and verified by qPCR and Western blot experiments. The NPC1L1 gene overexpression plasmid was constructed. The expression levels of N-cad, E-cad,… More >

Abstract Solving intrinsic structural problems such as low conductivity is the main challenge to promote the commercial application of Li₂TiSiO₅. In this study, Li₂TiSiO₅ is synthesized by the sol-gel method, and the surface modification of Li₂TiSiO₅ is carried out at different temperatures using low-temperature plasma to enhance its lithium storage performance. The morphological structure and electrochemical tests demonstrate that plasma treatment can improve the degree of agglomeration. The peak position of the plasma-treated Li₂TiSiO₅ is shifted to a lower angle, and the shift angle increases with increasing sputtering power. Li₂TiSiO₅ after 300 W bombardment shows excellent capacity (144.7 mA·hg⁻¹ More >

Abstract

Cobalt sulphides attract much attention as anode materials for Li-ion batteries (LIBs). However, its poor conductivity, low initial column efficiency and large volume changes during cycling have hindered its further development. Herein, novel interlaced CoS nanosheets were firstly prepared on Carbon Fiber Cloth (CFC) by two hydrothermal reactions followed with carbon coating via carbonizing dopamine (CoS NS@C/CFC). As a freestanding anode, the nanosheet structure of CoS not only accommodates the volume variation, but also provides a large interface area to proceed the charge transfer reaction. In addition, CFC works as both a three-dimensional skeleton and an

Abstract A one dimensional isothermal model is proposed by modelling the kinetics of methanol transport at anode flow channel (AFC), membrane and cathode catalyst layer of direct methanol fuel cell (DMFC). Analytical model is proposed to predict methanol cross-over rate through the electrolyte membrane and cell performance.

Abstract Three-dimensional C/SiOx nanofiber anode was prepared by polydimethylsiloxane (PDMS) and polyacrylonitrile (PAN) as precursors via electrospinning and freeze-drying successfully. In contrast to conventional carbon covering Si-based anode materials, the C/SiOx structure is made up of PAN-C, a 3D carbon substance, and SiOx loading steadily on PAN-C. The PAN carbon nanofibers and loaded SiOx from pyrolyzed PDMS give increased conductivity and a stable complex structure. When employed as lithium-ion batteries (LIBs) anode materials, C/SiOx-1% composites were discovered to have an extremely high lithium storage capacity and good cycle performance.
