分别以2种不同孔径和酸性的一维十元环结构分子筛ZIP-1(小孔)和BCM-168(大孔)为酸性组分制备了2种贵金属临氢异构化催化剂A200和B350,采用微型反应装置考察其对正十六烷的异构化反应性能,并对其产物进行倾点与收率的计算以模拟实际油品的切割效果。结果表明,孔径较大且Bronsted酸强度较弱的BCM-168分子筛制备的B350催化剂对正十六烷的异构化选择性更好,且在高转化率下A200与B350的选择性差距增大。通过对正十六烷异构产物进行模拟切割,发现2种催化剂反应产物的组成结构不同,B350催化剂异构化产物支化度更高。在实际油品评价中,通过分析产物烃组成与碳数分布,发现B350催化剂使烷烃断键生成碳数较接近的产物;而由孔径较小且Br?nsted酸强度较高的ZIP-1分子筛制备的A200催化剂,易促进烷烃多次裂解生成碳数较少的短链烷烃。同时发现,催化剂的过度异构化会使产物裂解为沸点较低的组分,使得目的产物大分子异构烃类收率降低。

目的观察硫化氢(H 2 S)对1-甲基-4-苯基-吡啶离子(MPP^+)所致SH-SY5Y细胞损伤的改善作用,并探讨其可能的机制。方法以500μmol/L的MPP^+诱导SH-SY5Y细胞损伤建立帕金森病模型,以硫氢化钠(NaHS)为外源性H2S供体。实验细胞分为3组:对照组、MPP^+组、NaHS+MPP^+组。应用CCK-8比色法检测细胞存活率;TUNEL法检测细胞凋亡;Griess试剂盒检测细胞培养液中的NO水平;ELISA法检测SH-SY5Y细胞培养上清液中IL-1β、IL-6、TNF-α水平;Western blot法检测iNOS、TLR4、IκBα及NF-κB的蛋白水平。评价H2S对该帕金森病细胞模型的影响。结果①500μmol/L的MPP^+可以导致SH-SY5Y细胞的存活率下降,凋亡率增加,经NaHS预处理可以使SH-SY5Y细胞的存活率增加,凋亡率降低;②MPP^+处理导致SH-SY5Y细胞IL-1β、IL-6、TNF-α、NO等炎症因子释放增加;NaHS预处理可以减轻此炎症损伤;③MPP^+处理组SH-SY5Y细胞TLR4增高,下游蛋白IκBα和NF-κB磷酸化水平增高,NaHS可明显抑制MPP^+所致TLR4/NF-κB通路的活化,减少NF-κB p65磷酸化,减少iNOS表达。结论H2S可通过抑制TLR4/NF-κB通路的激活,减少炎症因子的产生,减轻MPP^+所致SH-SY5Y细胞的炎症损伤。

A critical challenge to the commercialization of clean and high-efficiency solid oxide fuel cell(SOFC)technology is the insuf-ficient stack lifespan caused by a variety of degradation mechanisms,which are associated with cell components and chemical *** components related degradation refers to thermal/chemical/electrochemical deterioration of cell materials under operating conditions,whereas the latter regards impurities in feedstocks of oxidant(air)and reductant(fuel).This article provides a thermodynamic perspective on the understanding of the impurities-induced degradation mechanisms in *** discussion focuses on using thermodynamic ana-lysis to elucidate poisoning mechanisms in cathodes by impurity species such as Cr,CO_(2),H_(2)O,and SO_(2) and in the anode by species such as S(or H_(2)S),SiO_(2),and P_(2)(or PH_(3)).The author hopes the presented fundamental insights can provide a theoretical foundation for search-ing for better technical solutions to address the critical degradation challenges.

在当下智能传媒技术高速发展的时代,网络泛娱乐主义依托算法推荐不断强化精准传播,主要表现为以传播平台的多元化,营造受众对网络泛娱乐主义的在场体验;以传播内容定制化,诱导受众对网络泛娱乐主义的被动选择;以传播途径聚类化,促使受众对网络泛娱乐主义的盲目认同。算法推荐场域下网络泛娱乐主义精准传播具有深层的运作机理,体现为算法黑箱的“掩护”、拟态环境的“运用”、异化需求的“依托”、微观日常的“偏向”。为有效应对算法推荐场域下网络泛娱乐主义精准传播,需要持续推进算法研究,探索网络泛娱乐主义精准传播的反制技术;需要以主流价值嵌入算法,增加网络泛娱乐主义对算法的驾驭难度并挤压其传播空间;需要提升素养洞察算法,增强受众对网络泛娱乐主义精准传播的理性认知与抵制自觉;需要健全机制规制算法,强化消解网络泛娱乐主义精准传播的外在保障。
