Graphene replaced with copper Graphene nanoribbons have a current-carrying capacity two orders of magnitude higher than copper Recent research into the properties of graphene nanoribbons provides two new reasons for using the material for interconnects in future computer chips. In widths as narrow as 16 nm‚ graphene has a current-carrying capacity approximately a thousand times greater than copper while providing improved thermal conductivity. The current-carrying and heat-transfer measurements

Copper vs. Fiber Modern telecommunication networks rely primarily on two types of cable. Older copper cables have been replaced in many cases by fiber optic "light pipes‚" first in undersea cables and major intercity trunks‚ and later directly to many homes and businesses. Principles Copper cables carry information as an electrical signal‚ which may be digital‚ as in phone lines‚ or analogue‚ as in audio speaker cable. In optical fibers‚ however‚ data is carried digitally by light from a laser

A REVIEW PAPER ON MINE FIRE IN INDIA INTRODUCTION The problem of mine fire is as old as the history of the mine. The fires in coal mines are posing great hazard due to its increasing trend in the world and much more so in our country while mining of thick and thin seams under difficult geo-mining conditions. Due to fires in underground as well as surface mines‚ not only a considerable amount of resources is lost‚ but the entire mine environment is badly affected. So long as the fires are restricted

begin to talk about quality‚ many people would immediately think about French wines‚ which have gained a important fame in international markets. Nevertheless‚ during recent decades other wines have also gained lots of recognitions‚ and if we analyze quality wines in worldwide rankings we could get to know Chilean wines easily. Wines in Chile have known how to remain successful for a long time and this is not just a matter of luck‚ but an element of devotion and knowing how Chilean geography can

A printing press is a machine engineered for the purpose of mass fabricating and duplicating text and images in a short amount of time with the use of metal type or plates. The very first printing press with movable type‚ where the type can be moved and rearranged to form new and different text‚ dates back in China in 1‚000 A.D‚ created by a man named Pi Sheng. However‚ due to the complexity of the Chinese language‚ which contains thousands of characters‚ the printing press was proven void as it

Persuasive Paper: Trapped Chilean Miners On Thursday‚ August 5‚ 2010‚ thirty-three Chilean mine workers became trapped 2300 feet underground after the San Jose mine entrance ramp in collapsed. With the escape shaft blocked off‚ there was not a way for them to evacuate safely‚ as well as no clear way for the 130 man rescue team to get inside to free the miners. Once communication had been set up between the miners and the rescue team‚ it was found that all of the miners were still alive.

a man named Johannes Gutenberg; the man who invented the printing press. The printing press is one of those inventions that most people take for granted and do not realize their importance. Without the press we would still be handwriting every single copy of any book every written and so the question is what were the main consequences of the printing press? That is‚ what happened as a result of the invention of the printing press? The answer is that it marked the transition from script to printing

Printing Press and a Changing World The Development of Print Technology In the mid-15th century Johannes Gutenberg invented a mechanical way of making books. This was the first example of mass book production. In his workshop‚ he brings together the technologies of paper (brought from China to Italy in the 12th)‚ oil-based ink (these had been around since the 10th century) and the wine-press (screw-type press that had been in use for hundreds of years‚ throughout Europe and Asia) to print books
