Hydrogen Car

ydrogen-powered cars could one day store fuel safely and efficiently using polymers filed with nanoscopic holes. Researchers have achieved a new record for entrancing atomic number 1 using such nanoporous polymers. Frantisek Svec at the Lawrence Berkeley National Laboratory, California, and jean Fréchet, at the University of California in Berkeley, both in the US, revealed the feat at the International sexual intercourse of Nanotechnology, held in San Francisco amid 30 October and 2 November. atomic number 1 is tipped as a fuel of the future, as it can by use to contribute electricity cleanly, generating only water as waste. However, it essential commonly be stored as a liquid, under essential pressure, which invites it costly to process and dangerous to handle. So the hunt is on to set out a storage medium that lead absorb total heat readily and could, in future, be use to transport it chintzily and safely. This could be used inside a vehicles fuel tank and within containers used to transport hydrogen around the country. soaking up physical object The US Department of Energy (DoE) has set a target of purpose squares capable of holding enough hydrogen to make up 6% of its own total mass by 2010. just these must also release hydrogen cursorily if it is to be used to refuel vehicles.

Svec and Fréchet created nanoporous polymers by hotness and chemically treating styrene - an abundant hydrocarbon used to manufacture nearly plastics. The resulting real has an abundance of pores, each less than 2 nanometres in diameter. Hydrogen atoms naturally stick to the polymer, when coole d to around 77 one gm (-196°C), by formin! g surface bonds. This allows them to pack tightly inside the physicals pores. The material then releases the hydrogen when the temperature is raised or the pressure is reduced. naturally occurring Svec and Fréchet found that at roughly 40 measure atmospheric pressure, the nanoporous polymers contained 3.8% hydrogen. And, at atmospheric pressure, they contained 1.5% hydrogen....If you want to get a full essay, order it on our website: BestEssayCheap.com
