Carlin is where gold mining began for Newmont. In 1961, Newmont geologists began probing the high desert area around the Tuscarora Mountains in search of finely disseminated gold - gold that could be seen only in a microscope and, thus, had eluded earlier prospectors.
历史概述 Carlin是纽蒙特金矿的发源地。1961年,纽蒙特的地质人员开始在Tuscarora山四周的高沙漠地带寻找细颗粒浸染型金—一种极为细小,只有用显微镜才能看见的金子,所以以往的勘探人员都未能发现。1963年夏季通过钻孔和化验划定了一个 300万盎司的矿床,即使当时的金价每盎司只有35美元,该矿山也具有开采价值。

In this study, we developed the ammonia sensing material by using MCM-41 impregnated with bromocresol green. MCM-41 is one kind of mesoporous molecular sieves. It can be applied to many fields due to well-defined pore shapes, narrow distribution of pore sizes, large pore volumes, high surface area, excellent thermal, hydrothermal, chemical and mechanical stability. And the bromocresol green dye is commonly used as a pH indicator with colorimetric from pH 3.8 to pH 5.4.
本研究之目的是结合变色染剂及中孔洞分子筛MCM-41进行氨气吸附,研究中所选择之变色染剂溴甲酚绿是一种偏酸性之大分子有机染剂,其变色范围在pH 3.8到pH 5.4;而MCM-41由於其孔洞大小分布范围狭窄、孔洞体积大、高比表面积、具有良好的吸附容积、表面反应性强及易於改质等优点,故期望利用此复合材料,经气体吸附达到氨的移除并同时在吸附饱和前能产生显色效果。
