hurdle in efforts to begin commercial production of a form of carbon that could rival silicon in its potential for revolutionizing electronics devices ranging from supercomputers to cell phones. Called graphene‚ the material consists of a layer of graphite 50‚000 times thinner than a human hair with unique electronic properties. Graphene’s properties are remarkable. Impermeable to gas‚ strongest two dimensional material ever tested‚ with a tensile strength 200 times as great as that of steel‚ conducts

The purpose of this lab was to find out the reaction of iron nails and CuSO4‚ copper sulfate solution. Before starting the experiment‚ there were two possible outcomes of the reactions. CuSO4 + Fe → FeSO4 + Cu or 3CuSo4 + 2Fe → Fe2(SO4)3 + 3Cu. The ion chart showed that iron can only make two charges‚ +2 and +3. As the liquid evaporated‚ the weight changed because the liquid added to the nail’s weight. In a real world situation‚ scientists can use ratios to determine how much of a substance that

The Chernobyl Nuclear Power Plant Disaster It is a silent enemy‚ it has no odor‚ no smell‚ no shape‚ yet it is one of man’s deadliest foes. Radiation is not something most people face on a daily basis‚ but for the town of Prypiat in the Ukraine it is a barren wasteland because of it. The Chernobyl Nuclear Power Plant disaster was the worst nuclear catastrophe to have ever occurred and‚ is a perfect example of what can happen when the blind and unmasked furry of atomic power is left unharnessed

As technology continues to develop in sport‚ new composite materials are replacing the old traditional materials. Tennis rackets are no longer made of wood and sheep intestines but instead have been replaced with graphite and the strings are now made of nylon. This essay intends to discuss how old materials have been replaced by new composite materials‚ the manufacturing process and the benefits to the designer and consumer. Due to new technology‚ the tennis racket has changed materials. Throughout

The Physics of Fly-fishin’ What does it take to launch an ultra-light fishing line over 200 feet? A little physics and a lot of feel for the fishing rod‚ that’s what. The trick to doing good is to have the thinner‚ end of the line‚ land on the water first then the fly. The end of the line cushions the fly‚ having the effect that a fly is landing on the water‚ not a piece of nylon string. This may sound easy‚ but it’s a lot harder than it seems. Just getting it to go that far

and integrated. The availability of a new technology is only for a few groups of people—namely the part of society it is intended for and the richer families who can afford it. Take the pencil‚ for example; it was invented for woodworkers‚ as its graphite did not leave indentions on the wood. Then‚ it became available to artists‚ researchers‚ monks. Society initially fears a new technology until it has “authentication.” Baron demonstrates this fear

Spiritual Symbolism of the Wolf in Art Spirituality is one of the most dominant themes in art‚ and has been clearly portrayed by many artists throughout history which reflect the faith and beliefs of their time and culture. Spirituality is something we regard as intensely personal‚ or something we feel passionate about. For some‚ it is in a set religion‚ others a way of life‚ or in nature. Nature is a way many people can reflect themselves onto‚ creating a sense of oneness and divinity. In native
