| 1 | Nanostructural Features and Optical Performance of RF Magnetron Sputtered ZnO Thin Films显示文摘Zinc oxide (ZnO) thin films were grown on silicon substrate by RF (radio frequency) magnetron sputtering.Surface topography of these films exhibited a nanostructured granular appearance with the size of individual grains between 50 to 100 nm.Corresponding cross-sectional electron micrographs revealed columnar grains in the form of aggregated nanorods/wires with length of about 500 nm,similar to the thickness of these thin films of ZnO nucleated and grown vertically on the silicon substrate.High resolution lattice scale imaging using high resolution transmission electron microscope (HRTEM) elucidated the single crystalline 1010 planes of hexagonal-ZnO constituting the columnar grains with the individual nanorod diameter between 3 and 4 nm.The photoluminescence measurements showed the prominent emission peak at around 460 nm for the blue band,normally attributed to intrinsic defects in particular interstitial zinc (Zn).These films were further characterized by X-ray diffraction (XRD),Fourier transform infrared spectroscopy (FTIR),Raman spectroscopy and electron paramagnetic resonance (EPR) to evaluate various aspects on preferred growth orientations,band structures and vibrational modes originated in such fascinating nano-grained thin films of ZnO.The present investigations inferred that these films are advantageous in various potential applications for fabricating nano-scaled devices. | A.K.Srivastava Praveen M.Arora S.K.Gupta B.R.Chakraborty S.Chandra S.Toyoda H.Bahadur | 2010 | Journal of Materials Science & Technology2010，26，11： | 1 |

| 3 | Generalized Multiobjective Symmetric Duality under Second-Order(F, α, ρ, d)-Convexity显示文摘In this paper, we first formulate a second-order multiobjective symmetric primal-dual pair over arbitrary cones by introducing two different functions f : Rn × Rm → Rk and g : Rn × Rm → Rl in each k-objectives as well as l-constraints. Further, appropriate duality relations are established under second-order(F, α, ρ, d)-convexity assumptions. A nontrivial example which is second-order(F, α, ρ, d)-convex but not secondorder convex/F-convex is also illustrated. Moreover, a second-order minimax mixed integer dual programs is formulated and a duality theorem is established using second-order(F, α, ρ, d)-convexity assumptions. A self duality theorem is also obtained by assuming the functions involved to be skew-symmetric. | S.K.Gupta D.Dangar | 2015 | Acta Mathematicae Applicatae Sinica2015，31，2： | 0 |
| 4 | Cirus研究堆改造的安全评价显示文摘研究堆的总体安全目标是通过建立并保持有效的安全,保护电厂人员、公众和环境不受放射性危害。在Cirus堆目前的改造计划中,已经把改进和正在考虑的这一目标组合进一些系统、结构和部件。此外,设计阶段准备的初步风险评价报告已经改版成安全分析报告(SAR),符合最新的规程和导则。引入了假想事件后的详细分析,对诸如失水事故、停堆堆芯冷却无效/失效和一次冷却水系统调节阀门突然关闭之类的事故情况都进行了分析。在200%冷却剂轴向集管破裂期间,对放射性的最大可能释放途径的放射源项进行了估计,并进行了辐射剂量计算。 | S.K.Gupta 杨启友 | 2002 | 国外核动力2002，23，6： | 0 |
