storage and the like. At present‚ the productized graphene is mainly used in such fields as battery conductive additives‚ heat dissipating materials and composite materials‚ with products dominated by graphene powder and suspension prepared by oxidation-reduction method. Also‚ its costs have been reduced to within RMB10/g. In 2013‚ the industries including semiconductor electronics‚ energy (primarily battery) and composite materials showed the highest demand for graphene‚ which occupied 26%‚ 19% and

1800s. The cell that he made was not really a battery‚ but it was the most advanced attempt of making a battery in his time‚ it produced a steady electrical current‚ but did not work well over time; it was called the Voltaic pile. The voltaic pile was made of two electrodes of zinc and copper and sulphuric acid as the electrolyte. His name is used as the SI unit of electric potential. The volt is named after him in honour of making the first chemical battery. The Ohm Georg Simon Ohm was the father

Electricity and magnetism run nearly everything we plug in or turn on. Although it’s something we take for granted‚ it has taken hundreds of years of experimentation and research to reach the point where we flick a switch and the lights go on. Ancient Greeks knew rubbing amber generated static electricity‚ but they didn’t know why. The Greek word for amber is elektron. People knew about electricity for a long time. Ancient Greeks noticed that if they rubbed a piece of amber‚ feathers would

What is it? A pacemaker is a small battery-operated device that’s placed in the chest or abdomen to help control abnormal heart rhythms. Some pacemakers are external and temporary‚ not surgically implanted. The primary purpose of a pacemaker is to maintain an adequate heart rate‚ either because the heart’s natural pacemaker is too slow‚ too fast or has an irregular rhythm‚ this problem is called arrhythmias. A pacemaker can also relieve symptoms such as fatigue and fainting along with blockages in
