To ensure the safety of hydrogen refueling stations (HRSs) and protective targets in the surrounding area, this paper has introduced a risk-based safe distance assessment method for a 35MP HRSs, emphasizing the impact of the station's surrounding area. The findings indicate that the safe distance is determined by vapor cloud explosion (VCE) accident scenarios arising from pipeline leaks (compressor-hydrogen storage tanks) at 125 m. Therefore, a crucial focus should be placed on safeguarding and maintaining hydrogen pipelines. Furthermore, based on societal risk, the requirement of a 358-m safe distance specifies that the population gathering within this range should be © 2024 American Institute of Chemical Engineers.

Carbon dots (CDs)-promoted bioelectrochemical systems have shown promise for green power generation and waste water purification. However, most available CDs have the potential for toxicity and their size is not well-suited to bioelectrochemical systems. Here, ultra-small, biomass-based N-doped CDs were synthesized by a facile hydrothermal method using only the fresh leaves of Hydrocotyle vulgaris (also known as marsh pennywort). The CDs had an average diameter of only ~1.3 nm, were readily taken up by bacterial cells and showed good biocompatibility. The binding of the CDs with intracellular components of Shewanella oneidensis MR-1 markedly enhanced the electron transport channel within the cells, thus accelerating extracellular electron transfer (EET). The CDs boosted the metabolism of Shewanella oneidensis MR-1, as well as increasing bioelectricity generation by the bacteria. The current, voltage and power output of biocells constructed using CD-modified bacteria increased by ~12.2-, 3.0- and 14.1-fold compared with biocells constructed using unmodified bacteria. This work provides a feasible route to biomass-based CDs that can accelerate EET and thus boost bioenergy production. © 2023, The Authors. All rights reserved.

Hot-pressing-assisted fabrication of high-lignin-content and self-crosslinked strong adhesives

引用

Chemical Engineering Journal 2025年 514卷

作者： Yan, Li Liu, Haibo Wang, Ruonan Dai, Lin Yuan, Zhanhui Si, Chuanling State Key Laboratory of Bio-based Fiber Materials Tianjin Key Laboratory of Pulp and Paper Tianjin University of Science and Technology Tianjin300457 China College of Materials Engineering Fujian Agriculture and Forestry University Fuzhou350002 China

Lignin, a natural adhesive, provides sufficient mechanical properties for cell walls, inspiring its application in the field of wood adhesives. However, the majority of industrial lignin-derived adhesives necessitate the incorporation of copious quantities of crosslinking agents to guarantee their optimal mechanical properties. Nevertheless, this approach often gives rise to inherent limitations, including a deficiency in lignin content, environmental issues, and a complex reaction process that significantly impedes their green and large-scale applications. Here, a simple hot-pressing-assisted method was devised for the fabrication of a lignin-based adhesive (LGD). The LGD with an ultra-high lignin content of up to 86 wt% was synthesized from industrial alkali lignin by adding only a small amount of glycol diglycidyl ether (14 %) and a simple hot-pressing process. The LGD exhibited an exceptional bonding effect, with an adhesive strength of up to 8.98 MPa (three-layer plywood) and a modulus of rupture of 64.6 MPa (seven-layer plywood). This work not only provides a green raw material and application strategy for the adhesive industry, but also paves the way towards the high-value utilization and large-scale applications of lignin polymeric materials. © 2025 Elsevier B.V.
