Electronic engineering is an important field related to electrical engineering. Electronic engineers design and build modern day electronics, from telecommunication devices to medical machines to every day consumer electronics like your tablet.
There is a large number of consumer electric appliances like dishwashers, water heaters, indoor lighting and kitchen appliances that make modern life possible. Whenever you pop a piece of bread into a toaster or move a load of laundry to the drier you have an eletrcial engineer to thank. Learn more about this wide field of consumer appliances and electronics.
Graphene is basically a sheet of sp2 bonded atoms of carbon in the form of a hexagonal array. The name “graphene” comes from the words “graphite” and “-ene”. The most distinct property of graphene is that it can transport electrons at very high speed which is considered ideal for electronic devices.
Extracting gold from a printed circuit board can be a hectic process, but there are some methods that can be applied to remove minute quantities of gold from it. Also the amount of gold in PCBs vary. The PCB has to be evaluated for the amount of metal it contains before the process can be started.
