New Explosive Proves Unusually Touchy

Summary:
The first systematic study of a new group of explosives has concluded that the materials are so shock sensitive -- apt to detonate if struck or heated -- that the legendarily touchy nitroglycerin seems a pillar of stability by comparison.

The first systematic study of a new group of explosives has concluded that the materials are so shock sensitive -- apt to detonate if struck or heated -- that the legendarily touchy nitroglycerin seems a pillar of stability by comparison.

Conducted by Thomas M. Klapφtke and colleagues in Germany, the study is scheduled for the May 30 issue of the Journal of the American Chemical Society, a weekly publication.

In the study, researchers focus on newly developed chemical analogues, or variants, of two common high explosives in which carbon atoms have been replaced by atoms of silicon, the element in ordinary beach sand. Because of the extreme sensitivity of the compounds, which the researchers did not expect, only a limited number of tests could be performed before samples exploded.

A sample of one compound, for instance, exploded when touched gently with a small plastic laboratory spatula. Another sample exploded under a microscope. Measurements showed that the silicon analogue was more than 3 times more sensitive to impact than the parent compound.

The report states that the compound is "one of the most dangerous materials, and tends to explode on the slightest impact."

Crude Oil Prices Bounce Back After Falling Below $100 a Barrel

TheStreet (July 16, 2014) — Oil Futures are bouncing back after tumbling below $100 a barrel for the first time since May yesterday. Jeff Grossman is the president of BRG Brokerage and trades at the NYMEX. Grossman tells TheStreet the Middle East is always a concern for oil traders. Oil prices were pushed down in recent weeks on Libya increasing its production. Supply disruptions in Iraq fading also contributed to prices falling. News from China's economic front showing a growth for the second quarter also calmed fears on its slowdown. Jeff Grossman talks to TheStreet's Susannah Lee on this and more on the Energy Department's Energy Information Administration (EIA) report. Video provided by TheStreet
