Copper coils buried in the ground create a positively charged electrostatic field. All particles of ten nanometres or more -- including smog -- become positively charged, and thus attracted to the ...

You might have heard of electrets being used in microphones, but do you know what they are? Electrets produce a semi-permanent static electric field, similar to how a magnet produces a magnetic fie… ...

High-speed 4D STEM mapping with K3 IS and STEMx reveals electrostatic profile changes in MoS2/hBN heterostructures under bias.
