Despite an exponential increase in available data on marine plastic debris globally,information on levels and trends of plastic pollution and especially microplastics in the Arctic remains *** few available peer-reviewed scientific works,however,point to a ubiquitous distribution of plastic particles in all environmental compartments,including sea ***,we review the current state of knowledge on the sources,distribution,transport pathways and fate of meso-and microplastics with a focus on the European Arctic and discuss observed and projected impacts on biota and ecosystems.

以二茂铁和二茂镍为催化剂,采用化学气相沉积法在1 000℃下,炭黑(CB)转变为炭纳米微球和碳管。利用XRD,SEM,TEM,HR-TEM和Raman等对样品进行表征。结果表明,二茂铁和二茂镍质量比不同,可得到形貌不同的纳米炭的结构。与单金属催化剂相比,采用双金属催化剂合成的纳米炭结构具有高结晶度。催化剂颗粒填充在碳管内部或包裹在碳管外部,主要取决于催化剂与炭黑的质量比。当炭黑∶二茂铁∶二茂镍为1∶2∶2时,得到结晶度高的催化剂包裹多壁纳米炭微球结构。

这座儿童文化中心位于丹麦首都哥本哈根的Ama’r岛上,建筑所在的那个区域原来是这里的一个嘻哈舞蹈中心,被废弃的建筑还曾经是地下乐团的表演场地。如今这栋矗立在街角的建筑以其独特的外形吸引人们的注意,特别是铝制的外表皮,在阳光下闪闪发光。它与两栋砖混结构的建筑相连接,创造了一种独一无二的视觉效果。
