octanitrocubane造句

• For example, octanitrocubane and heptanitrocubane have been studied as high-performance explosives.
• Octanitrocubane is thought to have 20 25 % greater performance than HMX ( octogen ).
• When this witch's brew turned blue, Eaton knew he had arrived at the goal _ octanitrocubane.
• As with octanitrocubane, not enough heptanitrocubane has been synthesized to perform detailed tests on its stability and energy.
• Working with Mao-Xi Zhang he is reported as having been the first to make octanitrocubane in 2000 or earlier.
• But octanitrocubane interests chemists for another and more practical reason : it will probably be an ultra-powerful explosive that is reasonably safe to handle.
• Dr . Eaton said in an interview that within a matter of months chemists expect to synthesize octanitrocubane, a cube-shaped molecule with one nitrogen and two oxygen atoms at each corner.
• Only a few grams of this powdery white substance, called octanitrocubane ( ONC ), have been synthesized, and it has not been completely tested to determine its physical and chemical properties.
• In addition, octanitrocubane produces no water vapor making it less visible, and both the chemical itself and its decomposition products ( nitrogen and carbon dioxide ) are considered to be non-toxic.
• Partly because of this, Bashir-Hashemi said, octanitrocubane is expected to be a " super explosive " more powerful than HMX ( cyclotetramethylene-tetranitramine ), the most powerful military explosive in common use since World War II.
• While in theory not as energetic as octanitrocubane's theoretical maximum density, the HNC that has been synthesized so far is a more effective explosive than any ONC that has been produced, due to more efficient crystal packing and hence higher density.
• Until octanitrocubane is synthesized, its properties will remain somewhat speculative, but a kindred explosive synthesized by Bashir-Hashemi, tetranitrocubane ( in which four of the eight hydrogen atoms are replaced by " nitro groups " nitrogen-and-oxygen molecules ) turned out to be unexpectedly stable and safe.
• This enables engineers to determine the proper masses of different explosives when applying blasting formulas developed specifically for TNT . For example, if a timber-cutting formula calls for a charge of 1 kg of TNT, then based on octanitrocubane's R . E . factor of 2.38, it would take only 1.0 / 2.38 ( or 0.42 ) kg of it to do the same job.
• Dr . A . Bashir-Hashemi, a chemist at Geo-Centers Inc . under contract to the Army at the Picatinny Arsenal in New Jersey, predicted in an interview that octanitrocubane will be the most powerful chemical explosive ever devised, roughly twice as powerful as TNT . The Picatinny group, in cooperation with the University of Rochester in New York, also expects to develop a cubane-based liquid crystal that may have advantages over traditional liquid crystals.
