Previous studies have shown that exposure to black carbon(BC,a tracer of traffic-related air pollution)and psychosocial stress are both associated with adverse cardiac effects,but whether psychosocial stress could modify the cardiac effects of BC is *** investigate the potential modifying effect of psychosocial stress on the associations between acute exposure to BC and typical cardiac health variables,real-time personal 24 h measurements were conducted in a repeated-measure study among adults with elevated blood pressure(high-risk group)and a panel study among normal adults(low-risk group)in *** cardiac health variables included ST-segment depression events,heart rate,and heart rate variability(HRV)*** Stress Scale,State Anxiety Inventory and Self-rating Depression Scale were used to assess the recent psychosocial stress status of the participants,and a composite stress index was established based on these *** linear mixed-effects model was used to analyze the associations between BC exposure and cardiac health variables and potential effect modification by psychosocial stress.A total of 9724 h measurements among 97 participants in the repeated-measure study and 20224 h measurements among 87 participants in the panel study were included in the final *** BC exposure was significantly associated with increased ST-segment depression events and heart rate and decreases in HRV in both *** marginal effects of acute BC exposure on most cardiac health variables generally tended to be amplified under higher vs low levels of psychosocial stress in both studies,with the composite stress index apparently modifying the associations of BC exposure with most ST-segment depression events and HRV *** findings suggest that psychosocial stress may increase the participants’cardiac susceptibility to BC exposure,which could be helpful for the identification of susceptible individuals in the context of traff

高分散态铀氧化物对硝酸钾热分解的催化作用

南华大学学报（自然科学版） 2024年第3期38卷 90-96页

作者：刘璐马雅婷郁格格赵玉宝南华大学化学化工学院湖南衡阳421001

以SBA-15为载体,通过水热法制得高分散态的铀氧化物,而后引入KNO_(3)。基于程序升温分解-质谱(temperature programmed decomposition-mass spectrometry,TPDE-MS)联用技术,研究了KNO_(3)的热分解行为。利用KAS(Kissinger-Akahira-Sunose)方法和F 1/3方法分析了KNO_(3)热分解数据,得出相应的动力学参数。结果表明:纯KNO_(3)在600℃左右开始发生分解,分解率位于0.5~0.8时,其分解反应符合F 1/3方法模型函数,反应活化能为285 kJ/mol;高分散态铀氧化物上,KNO_(3)分解温度降低至200℃,分解活化能在205.4~207.3 kJ/mol之间。铀氧化物对KNO_(3)具有良好的催化活性,采用KAS和F 1/3方法得到KNO_(3)热分解的平均活化能分别降低了30和74 kJ/mol。

Chloride solid electrolytes possess multiple advantages for the construction of safe,energy-dense allsolid-state sodium batteries,but presently the chlorides with sufficiently high cost-competitiveness for commercialization almost all exhibit low Na-ion conductivities of around 10^(-5)S cm^(-1)or ***,we report a chloride solid electrolyte,Na_(2.7)ZFCl_(5.3)O_(0.7),which reaches a Na-ion conductivity of 2.29×10^(-4)S cm^(-1)at 25℃without involving overly expensive raw materials such as rare-earth chlorides or Na_(2)*** addition to the efficient ion transport,Na_(2.7)ZrCl_(5.3)O_(0.7)also shows an excellent deformability surpassing that of the widely studied Na_(3)PS_(4),Na_(3)SbS_(4),and Na_(2)ZrCl_(6)solid *** combination of these advantages allows the all-solid-state cell based on Na_(2.7)ZrCl_(5.3)O_(0.7)and NaCrO_(2)to realize stable room-temperature cycling at a much higher specific current than those based on other non-viscoelastic chloride solid electrolytes in literature(120 ma g^(-1)vs.12-55 ma g^(-1));after 100 cycles at such a high rate,the Na_(2.7)ZFCl_(5.3)O_(0.7)-based cell can still deliver a discharge capacity of 80 mah g^(-1)at25℃.
