4调强放疗计划多目标优化算法比较研究显示文摘目的探讨多目标优化(MCO)算法在调强放疗计划优化中的应用。方法随机抽取已接受治疗的10例前列腺癌和10例肺癌患者的调强治疗计划,这些计划都是基于直接子野优化算法进行优化的。在射野方向等设置条件不变前提下,改用MCO算法重新优化治疗计划。比较两种优化算法得到的剂量体积直方图参数、计划优化时间和机器跳数,并行配对t检验。结果两种优化算法得到的调强计划均满足临床要求。与DMPO算法相比,在靶区剂量分布无差别下MCO算法使得前列腺癌计划中的直肠、膀胱及小肠受量均有不同程度降低,计划优化时间减少58%,机器跳数平均增加32%;在肺癌计划中肺、心脏和脊髓受量均有不同程度降低,计划优化时间减少59%,机器跳数平均增加11%。结论与DMPO算法相比,MCO算法可显著降低危及器官受照剂量、缩短计划优化时间。廖雄飞 Jack Yang Yie Chen 黎杰 肖明勇 王培 2013中华放射肿瘤学杂志2013,22,4:8

7Carbon-based bifunctional electrocatalysts for oxygen reduction and oxygen evolution reactions:Optimization strategies and mechanistic analysis显示文摘Electrocatalysts are one of the essential components for the devices of high-efficiency green energy storage and conversion,such as metal-air cells,fuel cells,and water electrolysis systems.While catalysts made from noble metals possess high catalytic performance in both oxygen reduction reaction(ORR)and oxygen evolution reaction(OER),their scarcity and expensiveness significantly limit large-scale applications.In this regard,metal-free/non-noble metal carbon-based catalysts have become competitive alternatives to replace catalysts made of noble metals.Nevertheless,low catalytic ORR/OER performance is the challenge of carbon-based catalysts for the commercial applications of metal-air batteries.To solve the problem of poor catalytic performance,two strategies have been proposed:(1)controlling the microstructure of the catalysts to expose more active sites as the channels of rapid mass and electron transfer;and(2)reducing the reaction energy barrier by optimizing the electronic structures of the catalysts via surface engineering.Here,we review different types of bifunctional ORR/OER electrocatalysts with the activated surface sites.We focus on how the challenge can be overcome with different methods of material synthesis,structural and surface characterization,performance validation/optimization,to outline the principles of surface modifications behind catalyst designs.In particular,we provide critical analysis in the challenges that we are facing in structural design and surface engineering of bifunctional ORR/OER catalysts and indicate the possible solution for these problems,providing the society with clearer ideas on the practical prospects of noble-metal-free electrocatalysts for their future applications.Huidong Xu Jack Yang Riyue Ge Jiujun Zhang Ying Li Mingyuan Zhu Liming Dai Sean Li Wenxian Li 2022Journal of Energy Chemistry2022,31,8:2

20Molybdenum disulfide(MoS2)-based electrocatalysts for hydrogen evolution reaction:From mechanism to manipulation显示文摘Molybdenum disulfide(MoS_(2))-based materials as the non-noble metal catalysts have displayed the potential capability to drive electrocatalytic hydrogen evolution reaction(HER)for green hydrogen production along with their intrinsic activity,tunable electronic properties,low cost,and abundance reserves,which have attracted intensive attention as alternatives to the low-abundance and high-cost platinum-based catalysts.However,their insufficient catalytic HER activities and stability are the major challenges for them to become practically applicable.Hereby,the MoS_(2)-based electrocatalysts for HER are comprehensively reviewed to explain the fundamental science behind the manipulations of the crystal structure,microstructure,surface,and interface of MoS_(2) in order to enhance its catalytic performance through changing the electrical conductivity,the number of active sites,surface wettability,and the Gibbs free energy for hydrogen adsorption(ΔGH).Recent studies in surface/interface engineering,such as phase engineering,defect engineering,morphology design,and heterostructure construction,are analyzed to reveal the state-of-the-art strategies for designing and preparing the cost-effective and highperformance MoS_(2)-based catalysts through optimizing the charge transfer,surface-active sites,ΔGH,and surface hydrophilicity.Lastly,the perspectives,challenges,and future research directions of HER electrocatalysis are also given to facilitate the further research and development of HER catalysts.Yao Xu Riyue Ge Jack Yang Jiancheng Li Sean Li Ying Li Jiujun Zhang Jing Feng Bin Liu Wenxian Li 2022Journal of Energy Chemistry2022,31,11:1
