1 Rinse the mustard greens in water and drain. 2  Trim the stems of the greens and chop, if desired. 3  Place the greens in a skillet over low heat and cover. 4  Steam for 4 to 6 minutes or until the mustard greens are wilted, stirring occasionally so they do not stick to the pan. Rinse the mustard greens in cold water, drain and chop them up. 2  Place a skillet on medium heat and pour 2 to 5 tbsp. ( 3 29.58 to 73.95 ml) (in relation to the amount of mustard greens) of water or broth into the pan.
Electrostatic lens. An electrostatic lens is a device that assists in the transport of charged particles.[1][2][3] For instance, it can guide electrons emitted from a sample to an electron analyzer, analogous to the way an optical lens assists in the transport of light in an optical instrument.
The effects of static electricity are familiar to most people because people can feel, hear, and even see the spark as the excess charge is neutralized when brought close to a large electrical conductor (for example, a path to ground), or a region with an excess charge of the opposite polarity (positive or negative).areful grounding of part of an object with a charge-induced charge separation can permanently add or remove electrons, leaving the object with a global, permanent charge. This process is integral to the workings of the Van de Graaff generator, a device commonly used to demonstrate the effects of static electricity.
