This Could be the End for Big Oil
stunning breakthrough in chemical engineering has unleashed a massive supply
of fuel…
Enough fuel, in fact, to power the entire globe for over 36,000 years.
It’s poised to decimate Big Oil’s obscene profits, make OPEC obsolete, and
hand the United States 100% energy independence.
In fact, the U.S. Department of Defense just invested $7 billion in a single

在前面提到过，介孔是指孔径在2－50纳米之间孔。至于“介孔”这个名称的由来，我
想是介于“微孔”和“大孔”之间吧。它的另外一个名字就是“中孔”。恩，，在两者

mesostructured silicates －－－M41S。其基本过程包括：一种silica precursor，
tetraethylorthosilicate (TEOS)的在碱性条件下的水解（也可以用硅酸钠做
precursor），生成带负电荷的silicate nanocluster，然后与带正电荷的表面活性剂
分子（也被更广泛的称作structure-directing agent，就如tetramethyammonium

她还解释了辣椒水出现在现场的原因，称是因为环保人士不想使用化学物品，所以我们
希望这些辣椒水可以喷蟑螂、喷蚂蚁，或于耕种时使用。”
至于另一些液体，冯诗丽则说，其实是氢氧化钠（Sodium hydroxide），是制造有机肥
皂的材料。
冯诗丽还指出：“（现场）有很多刀具，菜刀及其他种类的刀具，其实都是我们清场的
时候，市民丢弃厨房用具的东西...... 我们会把这些刀具拿回来，之后再免费派出去
