3 have a suitable redox potential to drive the photo-oxidative reaction. These oxides might include those of vanadium aluminum titanium molybdenum calcium iron barium lead mangenese zinc copper nickle magne- sium chromium and silver. Valero Bruce Drum and Jay Neitz.

Since the electrons are attracted to the positive nuclei of the metal atoms they normally stay inside the metal and require energy to leave it. It can be used to study physical phenomena of special electron beams and to develop technological applications in electron microscopy that offer new and improved measurement techniques and increased resolution in different imaging modes. In a vacuum tube or electronic vacuum system the cathode is a metal surface which emits free electrons into the evacuated space.
