Near-field thermal radiation holds promise for high-throughput thermophotovoltaic devices,nanomanufacturing,thermal imaging,local heat removal,and vacuum thermal rectifiers,especially when the vacuum gap separating the structures is reduced to nanometer distances.Different micro/nanostructured materials have been considered for enhancing the radiative heat flux,such as doped silicon nanowires and nanoholes,carbon nanotubes,multilayers,gratings,and graphene sheets.This presentation will summarize some of the recent theoretical studies on photon tunneling in nanostructures considering surface plasmons,hyperbolic metameterials,as well as plasmonic graphene sheets.The tunneling efficiencies will be investigated in both the frequency and wavevector spaces.

锌具有平衡电位低、可逆性好、比能量高、成本低、无污染、资源丰富等诸多优点,因而在汽车、建筑、船舶、轻工等多个行业获得了广泛应用。然而锌作为两性金属,其化学性质特殊,在碱性环境中常涉及到钝化和溶解。因此,锌的腐蚀机理的研究在提高其防护性能的实际应用中具有重要意义。探讨锌在阳极溶解过程中的电流振荡行为不仅可以加深对锌腐蚀机理的认识,同时还可以丰富非线性科学。本文中采用循环伏安、恒电势等电化学方法考察了
