Journal of Energy Chemistry 2025年第1期100卷 286-308页

Methane, an abundant one-carbon（C1） resource, is extensively used in the industrial production of vital fuels and value-added chemicals. However, current industrial methane conversion technologies are energy-and carbon-intensive, mainly due to the high activation energy required to break the inert C–H bond, low selectivity, and problematic side reactions, including CO2emissions and coke deposition. Electrochemical conversion of methane（ECM） using intermittent renewable energy offers an attractive solution, due to its modular reactor design and operational flexibility across a broad spectrum of temperatures and pressures. This review emphasizes conversion pathways of methane in various reaction systems, highlighting the significance and advantages of ECM in facilitating a sustainable artificial carbon cycle. This work provides a comprehensive overview of conventional methane activation mechanisms and delineates the complete pathways of methane conversion in electrolysis contexts. Based on surface/interface chemistry, this work systematically analyzes proposed reaction pathways and corresponding strategies to enhance ECM efficiency towards various target products, including syngas, hydrocarbons, oxygenates, and advanced carbon materials. The discussion also encompasses opportunities and challenges for the ECM process, including insights into ECM pathways, rational electrocatalyst design, establishment of benchmarking protocols, electrolyte engineering, enhancement of CH4conversion rates, and minimization of CO2emission.

目的回顾性比较分析全机器人（daVinci）乳内动脉（IMA）游离小切口冠状动脉旁路移植术（CABG）和正中开胸术治疗单支血管病变，评估前者的疗效和安全性。方法2000年4月至2011年8月，解放军总医院心外科共完成194例单纯非体外循环单支CABG，根据手术方式分为正中开胸组（99例）和全机器人IMA游离、小切口CABG组（95例）。所有患者术前均有不同程度的心绞痛症状，经冠状动脉造影证实有严重的前降支（LAD）病变。小切口组以机器人游离IMA，再经胸部小切口徒手完成与靶血管的吻合。术中均以超声血流检测仪测量桥血管血流。术后以冠状动脉造影或64排CT评估桥血管的通畅性，并进行随访。结果小切口组呼吸机辅助时间和术后引流量优于正中开胸组，差异均有统计学意义[（5．1±2．1）h比（10．1±5．8）h，P=0．003；（411±295）ml比（605±244）ml，P=0．000]，两组桥平均血流量、病死率和并发症发生率差异均无统计学意义。术后早期CT检查及造影检查未发现桥血管狭窄。随访2个月至10年，均恢复正常工作生活。结论与正中开胸比较，全机器人IMA游离、小切口治疗单支病变是一种全新的术式，创伤轻、疗效肯定，手术安全。

国内GPS卫星信号模拟源大多基于"DSP+FPGA"架构进行开发研制,DSP与FPGA是两个独立的时钟域系统,存在异步数据交互的问题。基于解决DSP计算所得导航电文以及载波控制字、伪码控制字向FPGA传输时发生数据丢失问题得目的,提出采用异步FIFO来缓存大量导航电文数据还有同步器来同步所传输的载波控制字和伪码控制字的方法。通过采用Altera公司的FIFO内核来进行外围接口信号和控制逻辑设计以及两级触发器级联来实现同步器的试验设计方法,得到所设计的缓存导航电文的异步FIFO输出的数据结果正确以及系统稳定的结论。

目的研究^60Coγ射线对大鼠骨髓间充质干细胞（MSC）增殖和分化能力的影响；评价MSC移植对大鼠心梗后心功能的影响。方法MSC受照射后继续培养，检测增殖能力；5-氮胞苷（5-aza）诱导分化，检测C-心肌肌钙蛋白重链（C-TNT）、β-心肌肌球蛋白重链（B—MHC）的表达。建立大鼠急性心梗模型并行照射和非照射MSC移植，术后4周检测心脏大小和功能变化、并比较微血管密度的差异。结果4Gy组细胞增殖能力受抑制，C—TNT和β—MHC在未照射组有所表达。两细胞移植组较对照组术后心功能改善、心脏缩小，微血管计数值增加。结论移植正常和丧失分化能力的MSC同样能明显改善心梗后早期的心功能。
