燃料电池堆的端板质量与封装载荷均匀化分布程度直接影响电堆的功率密度、效率、可靠性和使用寿命。为了减少绑带封装质子交换膜燃料电池端板结构质量,提高电堆内部接触压力均匀性,通过数值仿真方法,基于等效刚度模型,建立了燃料电池电堆端板的二维拓扑优化模型。结果表明,底面平直结构的端板通过拓扑优化可以显著实现轻量化目标,但是无法在实现减重的同时提高堆体的压力分布均匀性,且在平均体积因子达到0.5时为最优结构;底面上倾结构端板能够明显改善电堆内部的接触压力均匀性。对底面上倾结构端板进行拓扑优化能够在减重的同时提升堆体的压力分布均匀性,当端板底面上倾高度为0.09 mm时,压力分布的均一性最好,综合评价指标也最优,因此拓扑优化可以为端板的结构设计提供理论参考。

SYNTHESIS　OF　1H，1＇H　BIS（BENZ－△~4－IMIDAZOLINE）2，2＇－SPIRO－TITANIUM　DICHLORIDE

The development of promising photodynamic therapy(PDT) agents that bind to DNA for cancer treatment have drawn much more attentions recently. In this work, Ir-containing luminescent metallohelices by using a preformed facial Ir(ppy) handle which decorated with three aldehyde groups, then condensed with linear diamine spacers through dynamic covalent chemistry were designed and synthesized for the first time. Interestingly, increasing the chain length of the alkanediamine precursor resulted in an odd–even alternation between chiral helicates and achiral mesocates. After postsynthetic reduction of imine linkages, the obtained chemically robust amine-linked metallohelices showed bright green luminescent emission, and specifically stain the mitochondria of living cells. In contrast to the helicates, the mesocates showed stronger DNA-binding affinities and DNA photocleaves abilities under visible light. Importantly, the amine-linked mesocate with the longest linkers exhibited the best PDT efficiency. This study demonstrates that alterations in helicate structures can have profound effects on PDT cytotoxicity towards cancer cells.

Risk prediction tools are crucial for population-based management of cardiovascular disease(CVD).However,most prediction models are currently used to assess long-term risk instead of the risk of short-term CVD *** developed a Dynamic Risk-based Early wAming Monitoring(DREAM)system using large-scale,real-time electronic health record data from 2010 to 2020 from the CHinese Electronic health Records Research in Yinzhou *** dynamic risk scores were derived from a 1:5 matched nested case-control set comprising 70,470 individuals(11,745 CVD events)and then validated in a cohort of 81,205 individuals(5950 CVD events).The individuals were Chinese adults aged 40-79 years without a history of CVD at *** predictors related to vital signs,laboratory tests,and health service utilization were selected to establish the dynamic *** proposed scores were significantly associated with the subsequent CVD onset(adjusted odds ratio,1.21;95%confidence interval,1.20-1.23).The area under the receiver operating characteristic curves(AUCs)was 0.6010(0.5929-0.6092)and 0.6021(0.5937-0.6105)for the long-term 10-year CVD risk10%group in the validation set,the change in AUC in addition to the long-term risk was 0.0235(0.0155-0.0315).By increasing the risk threshold from 7 to 16 points,the proportion of true subsequent CVD cases among those given alerts increased from 40.61%to 85.31%.In terms of management efficiency,the number needed to manage per CVD case ranged from 2.46 to 1.17 using the risk *** the increasing popularity and integration of EHR systems with wearable technology,the DREAM scores can be incorporated into an early-warning system and applied in dynamic,real-time,EHR-based,automated management to support healthcare decision making for individuals,general practitioners,and policymakers.
