Carbon dots(CDs) have received much attention due to their superior properties including water solubility, low toxicity, biocompatibility, small size,fluorescence, and ease of modification. The use of a more environmentally friendly method to prepare high-quality CDs is still an urgent question waiting for solve. The use of renewable, inexpensive, and green biomass resources not only meets the urgent need for large-scale synthesis biomass CDs(BCDs), but also promotes the development of sustainable *** this article, we summarize the representative methods for synthesizing BCDs in green and simple ways using biomass as a carbon source, including hydrothermal carbonization, and microwave, pyrolysis. The prepared BCDs have a uniform particle size distribution and a relatively high throughput,which provide a method to scale up industrial production. Moreover, the integration of specific optical properties, that is, tunable photoluminescence and up-photoluminescence, has led to remarkable use in bioimaging, sensing,and drug delivery. But the current review is not particularly comprehensive for BCDs. Therefore, we now provide a review focusing on the synthesis,properties, and recent advances in BCDs in biosensing, bioimaging,optoelectronics, and catalytic applications.

作为一类新型固液两相流体,纳米流体相比于基础流体,其导热系数、表面张力等热物性的优势已逐渐被认可。然而,纳米颗粒的高表面活性以及颗粒间的高吸引力使纳米颗粒极易团聚并沉淀,导致纳米流体的热物性优势被削弱,进而影响传热效果。因... 详细信息

作为一类新型固液两相流体,纳米流体相比于基础流体,其导热系数、表面张力等热物性的优势已逐渐被认可。然而,纳米颗粒的高表面活性以及颗粒间的高吸引力使纳米颗粒极易团聚并沉淀,导致纳米流体的热物性优势被削弱,进而影响传热效果。因此,制备既具优良热物性又具较强稳定性的纳米流体成为将其规模化应用的前提。为此,本文对纳米流体的制备、稳定性与热物性进行了总结分析,归纳了通过磁力搅拌、调节基液pH、超声分散技术、颗粒表面改性技术及添加表面活性剂以促进颗粒的稳定分散的技术特点。通过分析各类参数对纳米流体热物性的影响,指出解决颗粒团聚与沉淀问题的有效研究方向,以期满足纳米流体实际应用的需求。

以黑马关富水千枚岩公路隧道为依托,对隧道大变形控制技术进行深入探讨。通过对大变形破坏特征及成因分析发现,隧址区复杂地质构造作用致使千枚岩节理发育,其矿物成分及游离氧化物在节理中迁移进一步恶化岩体的力学性质;由于千枚岩具有较强的水敏性,长期受水浸泡后软化、泥化破坏严重,富水千枚岩隧道面临围岩强度低、易发生大变形的问题。现场监测数据分析表明:隧道大变形表现出明显的不对称性,隧道下导洞开挖后变形加剧。现场采用地下水封堵、支护参数强化、跳做双层腹拱等加固措施,对富水千枚岩隧道大变形段进行处治,效果表明:采用引水封闭+双层腹拱跳做施工工艺,可有效控制千枚岩长期浸水软化导致的不对称大变形,且施工便捷、经济性更好。

面对十七世纪女性意识觉醒与生态破坏两大剧变,约翰·弥尔顿省思这些挑战并在其史诗《失乐园》中,将相关思想融入对夏娃与自然的刻画。本文揭示弥尔顿的观点,包括承认女性与自然之相似性、尊重存在物之差异性并构建地球共同体。其观点具有革命性与前瞻性,本质上可界定为“早期生态女性主义观点”,因而对后来的生态女性主义思想有先驱性贡献。本研究不仅有助于读者理解英国早期现代的社会剧变,亦揭示弥尔顿的早期生态女性主义观对当代社会的重要启示。
