Compared with thermodynamically equilibrium supramolecular assemblies, non-equilibrium assemblies from the same building blocks have attracted increasing attentions because their diverse structures and dynamic natures may impart the assemblies with novel functionalities. However, facile access to non-equilibrium assemblies remains a formidable challenge. Herein, we endeavored to exploit various solvent-anti-solvent methods to achieve it using peptide amphiphile C16-VVAAEE-NH_(2) as a model. Through systematical utilization of dialysis, ultrasonic and stirring-dropping methods, as well as tuning of processing parameters, we demonstrated the successful formation of diverse non-equilibrium nanostructures with distinct morphologies and structures that significantly deviate from the thermodynamically favored twisted long ribbons. Additionally, these metastable nanostructures ultimately underwent spontaneous transformation into thermodynamically stable states. The transformation processes of three representative non-equilibrium assemblies were also demonstrated and characterized in detail using transmission electron microscopy, circular dichroism spectrum, and thioflavin T fluorescence spectrum. Furthermore, non-equilibrium assemblies exhibited various degrees of cytotoxic effects, which may stem from their spontaneous, dynamic transformation and interactions with cellular membranes. This study offers valuable approaches for direct access to diverse non-equilibrium supramolecular nanostructures from self-assembling peptide, and also has implications for the development of advanced materials with unprecedented biological functions.

分别采用石墨烯涂料和银粉漆对地板表面进行改性,制备了表面发射率分别为0.86和0.46的地板。采用地板供暖实验装置测试了不同发射率表面的地板供暖性能,结果表明在热源温度分别为28℃、3 6℃、4 1℃的情况下,表面发射率为0.86的地板比表面发射率为0.46的地板表面温度分别升高1.6℃,1.1℃和0.5℃,总供热量分别增大25.4 W/m^(2),3 5.2 W/m^(2)和42.9 W/m^(2)。对不同发射率的地板表面供暖性能进行了计算,计算结果与实测数据误差约为3%。研究了地板表面发射率对地板辐射换热量的影响,结果表明辐射换热量随地面发射率增大近似线性增大,且对于较高的热源温度,对应的线性斜率相应增大。

International Journal of Mining Science and Technology 2017年第1期27卷 165-170页

作者： Guo wenbing Tan Yi Bai Erhu iaozuo 454000 China Synergism Innovative Center of Coal Safety Production in Henan Province Jiaozuo 454000China

It is important to study the mining technology under structures for raising the coal resources recovery ratio. Based on the geological and mining conditions, the top coal caving harmonic mining technique in thick coal seam beneath the earth dam was put forward and studied. The 5 factors such as the panel mining direction, panel size, panel location, panel mining sequence and panel advance velocity were taken into account in this technique. The dam movement and deformation were predicted after the thick coal seam mining and the effects of mining on the dam were studied. By setting up the surveying stations on the dam, the movement and deformation of the dam were observed during mining. By taking some protective measures on the dam, the top coal caving mining technique in thick coal seam beneath the earth dam was carried out successfully. The study demonstrates that harmonic mining in thick coal seam is feasible under the dam. The safety of the earth dam after mining was ensured and the coal resources recovery ratio was improved.
