High-efficiency and cost-effective catalysts with available strategies for persulfate(PS)activation are critical for the complete mineralization of organic contaminants in the environmental remediation and protection fields.A nanoscale zero-valent iron-embedded modified mesoporous carbon(MCNZVI)with a core-shell structure is synthesized using the hydrothermal synthesis method and high-temperature *** results showed that nZVI could be impregnated within mesoporous carbon frameworks with a comparatively high graphitization degree,rich nitrogen doping content,and a large surface area and pore *** material was used as a persulfate activator for the oxidation removal of Reactive Black 5(RB5).The effects of the material dosage,PS concentration,pH,and some inorganic anions(i.e.,Cl^(−),SO_(4)^(2−))on RB5 degradation were then *** highest degradation efficiency(97.3%)of RB5 was achieved via PS(20 mmol/L)activation by the MCNZVI(0.5 g/L).The pseudo-first-order kinetics(k=2.11×10^(−2)min^(−1))in the MCNZVI/PS(0.5 g/L,20 mmol/L)was greater than 100 times than that in the MCNZVI and *** reactive oxygen species(ROS),including^(1)O_(2),SO_(4)^(·−),HO^(.),and·O_(2)^(−),were generated by PS activation with the *** oxygen was demonstrated to be the primary ROS responsible for the RB5 *** MCNZVI could be reused and regenerated for *** work provides new insights into PS activation to remove organic contamination.

High mobility group box-1 protein(HMGB1)is an evolutionarily ancient protein,which,as an important non-histone chromosome-binding protein in organism cells,is involved in a variety of important biological processes,including DNA repair,gene transcription,cellular inflammatory response,and *** this study,we established an eccentric exercise model to observe the effect of HMGB1 on skeletal muscle autophagy and to investigate the underlying molecular ***-eight male 8-week-old SD rats were randomly divided into control group(C)and exercise group(E).Group E was subjected to a bout of eccentric exercise on a treadmill and sampled soleus at 0 h,12 h,24 h,48 h,and 72 h *** speed of the exercise protocol in this study was 16 m/min,the slope was−16°,and the time was 90 *** ultrastructural changes of skeletal muscle were observed by transmission electron *** protein expressions of HMGB1,Beclin1,and LC3 were detected by Western *** co-localizations of Beclin1/Bcl-2,Beclin1/HMGB1,and Beclin1/Vps34 were measured by *** results show that eccentric exercise leads to abnormal changes in the ultrastructure of skeletal muscle,and the protein levels of Beclin1,LC3-II/LC3-I,and the content of HMGB1 in nuclear and cytoplasm were significantly increased at 24 h post-exercise(P<0.05).The co-localization of Beclin1/Bcl-2 and Beclin1/HMGB1 were increased significantly at 0 h post-exercise and then decreased,while the co-localization of Beclin1/Vps34 showed the highest level at 24 h *** conclusion,HMGB1 facilitates the separation of Beclin1 from Bcl-2 and promotes Beclin1 binding to Vps34,which may play an important role in eccentric exercise-induced skeletal muscle autophagy.

为改善除尘滤芯脉冲喷吹清灰不良的问题,以异形滤芯为研究对象,考察了滤芯形状、喷吹角度和喷吹压差组合条件下的脉冲喷吹性能,构建脉冲喷吹的数值模型,运用Ansys Fluent软件对滤芯内部流场进行模拟及分析。结果表明:倒梯形和收缩形滤芯内对撞区的静压较大,梯形和鼓胀形滤芯内静压区较小;喷吹角度从-45°增加到45°,直筒形和收缩形滤芯的喷吹压力和喷吹性能整体表现为先增后降的趋势,最佳喷吹角度为30°;增大喷吹压差PR有助于提高滤芯的喷吹性能,并且压差对于收缩形滤芯喷吹性能的提升要强于直筒形滤芯。总体上,除尘滤芯的收缩形结构有利于提高对撞脉喷清灰性能。
