The global energy crisis has intensified the need for sustainable energy solutions, yet conventional energy production still relies on non-renewable, environmentally damaging materials. Although significant advances have been made in green energy technologies, a critical gap remains in the development of materials that are both renewable and environmentally friendly. Bio-based materials, derived from renewable resources, offer a timely and sustainable alternative that can significantly improve the efficiency, functionality, and environmental compatibility of energy conversion devices. This review highlights the role of bio-based materials in addressing these challenges, focusing on their applications in emerging green energy technologies, particularly triboelectric nanogenerators (TENGs), piezoelectric nanogenerators (PENGs), and solar-powered seawater desalination systems. It provides a comprehensive overview of the latest advances in preparation methods, material properties, and their practical applications in energy conversion systems. By discussing the unique advantages and material selection challenges, this review underscores the importance of bio-based materials in the continued development of sustainable, high-performance energy harvesting devices. Furthermore, it emphasizes their potential to contribute to global sustainability goals, offering a critical pathway to more eco-friendly and cost-effective energy solutions. © 2025 Elsevier B.V.

Ni-based alloys have attracted much attention due to their exceptional mechanical and corrosion properties. The combination of these excellent properties has increased researchers’ interest in studying passivation mechanism during corrosion and tribocorrosion. In the present study, the effects of Mn addition (Mn = 0, 5, 10, and 20 at.%) on wear, corrosion, and tribocorrosion behavior of Ni-based alloys were investigated under room temperature. The microstructures of as-fabricated and post-test Ni alloys were characterized by X-ray diffraction and scanning electron microscopy. The elemental distribution and chemical states in worn and unworn areas were identified by using energy dispersive X-ray spectroscopy and X-ray photoelectron spectroscopy. The addition of Mn in the alloy was found to increase wear and tribocorrosion resistance. Pitting potential of Mn-free alloys was higher than that of Mn-containing alloys, reducing from 0.56 V to −0.05 V. Higher Mn concentration in the alloy offered a wear-induced corrosion during tribocorrosion process. In addition, substituting Cr with Mn content can promote the passivation of Ni, which was confirmed by X-ray photoelectron spectroscopy. Although Ni-Mn alloys does not passivate thermodynamically, passive layers can be found by transmission electron microscopy analysis due to the formation of metastable oxide phases. © 2025 Elsevier B.V.

The effect of moisture on the crystallization and morphological control of spray-prepared Cs0.19FA0.81PbI2.5Br0.5 perovskite films is elucidated. Moisture in air functions to (1) enhance droplet spreading as a result of humidity-suppressed solvent evaporation;(2) solvate organic salts in conjunction with added water in the precursor solution to facilitate the penetration of organic salts into inorganic halide films and accelerate their interaction. These conjunct contributions, on the one hand, relieve inhomogeneous solute distribution and suppress the "coffee-ring effect", on the other hand, promote phase transition and improve the crystallinity of resultant perovskite, ultimately enabling the formation of high-quality Cs0.19FA0.81PbI2.5Br0.5 perovskite films with homogeneous morphology and good crystallization. The power conversion efficiency (PCE) of the champion perovskite solar cell increases from 18.25% to 19.74%, with improved thermal stability, maintaining 80% of its initial efficiency after operating at 50 °C for >800 h. The large-area perovskite film (10 × 10 cm2) exhibits significant uniformity over the entire film, and the corresponding devices exhibit high consistency and reproducibility. The average PCE of small-area devices employing the same large-area perovskite film is 19.53±0.25%. Mini-modules with an active area of 64.8 cm2 yield an optimal PCE of 16.75%, with an average PCE of 16.08±0.32%. © 2023, The Authors. All rights reserved.

Li metal batteries(LMBs)are regarded as promising future high-energy batteries,but their practical application under the conditions of high current density and large areal capacity is impeded by Li dendrite growth and low Coulombic efficiency(CE)[1–4].This is largely due to the structural heterogeneity and mechanical fragility of the native solid-electrolyte interphase(SEI)formed in situ on the Li metal surface,which cannot stabilize and protect the Li anode[5–7].

Synergistic Strengthening of Al Matrix Composites by in Situ Pyrolysis of C and Precipitation of Nanophases

SSRN

引用

SSRN 2023年

作者： Sun, Yi Li, Junguo Yang, Xuebin Li, Peibo Zhang, Yang Luo, Guoqiang Shen, Qiang State Key Laboratory of Advanced Technology for Materials Synthesis and Processing Wuhan University of Technology Wuhan430070 China Chaozhou Branch of Chemistry and Chemical Engineering Guangdong Laboratory Chaozhou521000 China Hubei Longzhong Laboratory Hubei Xiangyang441000 China

This study focuses on addressing the dispersibility issue of carbides in Al matrix composites through the in-situ pyrolysis of polymers. Furthermore, the addition of Ag enables Ag-C synergistic reinforcement of Al matrix composites, offering a novel reinforcement approach for Al matrix composites. The Al-16Ag-C composite is fabricated through the in-situ pyrolysis of PVB (Polyvinyl Butyral) followed by hot pressing sintering. Subsequently, the effect of temperature on the microstructural evolution and mechanical properties of the composite is investigated. The underlying strengthening mechanisms are also examined and discussed. Microstructural characterization demonstrates the formation of two alloy phases, namely Ag2Al and Al4C3, within the Al-16Ag-C composite. The formation of Al4C3 is dependent on the temperature utilized during sintering. The alloy phases, distributed at the grain boundaries, enhance the material’s strength by impeding dislocation motion, increasing dislocation density within the matrix, and limiting grain growth. The Al-16Ag-C composite, sintered at 630 °C, exhibits a remarkable ultimate tensile strength of 481 MPa and an elongation of 22.25%, representing a significant enhancement compared to pure aluminum. © 2023, The Authors.
