简介：荧光灯颜料，基于光或染料的electrooptical性质，是主要部件在荧光灯涂层和墨水。在这研究，三种染料(玫瑰精B，轻格林SF微黄色，香豆素)与四不同比率(2.5?wt%，3?wt%，3.5?wt%，4?wt%)作为发光体被采用，并且三聚氰胺甲醛(MF)树脂被用作治好树脂准备荧光灯在不同颜色的颜料。Fourier变换红外线的光谱学和X光检查diffractometry被执行分析结构荧光灯颜料。扫描电子显微镜学和粒子尺寸分发被用来介绍形态学荧光灯颜料。紫外力并且荧光光谱被用来表明光性质。这能被结束，当玫瑰精B可能是为从粒子尺寸的看法在三种染料之中打印墨水的准备的最好时，香豆素颜料在MF树脂拥有了连续结构。TG结果介绍了那所有颜料显示出好热稳定性，它可能在高速度打印拥有潜在的申请工业。

简介：在2005和2006收集的表面沉积样品的Geochemical分析被用来评估在东南波兰Solina水库的沉积在场的有机物的潜在的来源。沉积变量的统计分析(碳到氮比率，和碳13和氮15同位素比率)决定了因为器官的部分关于有机物的来源显示了重要空间可变性。一个二进制混合模型从文学来源被开发预言属曾被地壳动力搬、本土的生产的相对贡献到沉积有机物。本土的生产被显示在水库的湖的部分说明体积沉积的60-75%，在水坝附近。相反，本土的生产说明了因为仅仅在收到流的河流的地区的25%沉积输入。统计分析识别了15有机物的N作为有机物的来源的最好的预言者。多重回归分析显示二个水质量变量(硝酸盐和溶解硅石)是显著地与15有机物的N签名。这导致了那湖泊的硝酸盐和溶解硅石集中在Solina水库正在调整有机物生产的一个结论。
