The copper is used to support the polymer layer on which the particles/object of interest is deposited. You need a thin layer of polymer/carbon because in TEM you measure transmitted electrons, so the electrons need to be able penetrate the material on which the sample is deposited. A few micrometers of material can already absorb all the electrons. The copper is just to support this polymer layer and to make a sample which is easy to handle.

How do smart grids differ from the current electricity infrastructure in the US?
smart grids are different from the existing infrastructure in the united states because it is much capible to destribute electricity more efficiently and of allowing communications between the various systems of the grid, and they also provide the consumer the detail of there usage and guide them how to reduce there consumption because they exist on modern technology. but the other old existing infrastructure is based on old technology, they have there old destribution plan, line losses and not able to know the usage of every consumer and the peak hours of usage like the smart grids that's why the reason smart grids are better then old electricity infrastructure.
What is the conclusion in alternating current and measurement?
The only thing that can be concluded about alternating current is that it alternated at 50 or 60 Hz throughout the grids around the world.
What do solar flares look like?
Solar flares appear as sudden and intense bursts of energy erupting from the Sun's surface. They can emit visible light, UV rays, and X-rays, and may appear as bright flashes or protruding loops from the Sun's surface. When observed from Earth, they can sometimes cause disruptions in satellite communications and power grids.
Is electricity natural or man-made?
Electricity is a natural phenomenon that can be harnessed and utilized by humans for various purposes. Man-made systems, such as power plants and electrical grids, help generate and distribute electricity for our use.

What is a hanger wire made of?
A hanger wire is typically made of galvanized steel, which is coated with a layer of zinc to protect it from corrosion. This material is commonly used in construction applications to hang ceiling grids, light fixtures, and other suspended elements.
Why do archaeologist create grids?
Archaeologists create grids because it makes it easier for them to measure where things were found, and where they have dug. Without grids it would be easy to become confused.
Are the two grids in the stinger bug zapper conected together?
The two grids are not connected together. There is a high voltage difference between the two grids. When the bug tries to crawl through the grids to get to the light, it completes the circuit and the electricity passes through the bug. The electricity is what kills the bug.
