  • 简介:Au/Al_2O_3/Al金属/绝缘体/金属连接(MIMJ)和Au/SiO_2/Simetal/insulator/Si连接(MISJ)成功地被构造了。这些连接的轻排放被表面电浆子电磁声子(SPP)在表面粗糙下面调停。从MISJ的轻排放从MIMJ比那更一致、稳定。MISJ的轻力量比MIMJ的高是大约2份~3订单。MISJ的轻排放光谱特别被分析。在光谱,有一座主要山峰在610nm~6的波长定位了40nm,它主要由于有在Au/air和Au/SiO_2接口的表面粗糙的SPP的夫妇。在更短的波长区域位于光谱的一座弱山峰也被发现,它被doped-Si血浆摆动的直接放射引起。

  • 简介:在自然,微生物涉及岩石捱过,在从矿物质的金属的动员,并且在金属降水和免职。这些微生物原则和过程能被改编对待微粒固体浪费。特别从金属珍视获得的稳固的矿物质(沥滤的称为的简历)的金属的微生物增溶是在采矿工业的一种著名技术。我们这里集中于非采矿矿物质浪费为包含金属的稳固的浪费的处理表明基于采矿的技术的适用性。从微粒苍蝇灰的在案例研究介绍的、微生物引起的金属动员(从市政的稳固的浪费焚化发源)而铅,铬,和镍被2,11和32%分别地动员,由Acidithiobacilli导致了>80%的镉,铜,和锌动员。另外,形成HCN细菌的潜力(Chromobacteriumviolaceum,Pseudomonasfluorescens)当面对稳固的材料成长时,被调查动员金属(例如,包含铜的矿石,电子碎片,花的汽车催化变换器)。C。violaceum从有细密纹理的镍粉末作为tetracyanonickelate动员镍被发现有能力。黄金是微生物引起地是的solubilized从电子废物的dicyanoaurate。另外,氰化物建筑群铜在切碎的打印电路板碎片的生物处理期间被检测。水溶性的铜和铂氰化物也在花的汽车的处理期间被检测催化变换器。
