Abstract: Energy consumption of the society is increasing due to expanding economic activity and increasing population. As greater consumption of energy generates more air pollution, there is an ongoing need to find better methods of reducing pollutants in terms of effectiveness and reduced energy consumption. The solution proposed in this disclosure takes advantage of electrical characteristics such as electron affinity and dipole moment. There are many pollutants which exhibit positive electron affinity. Such a pollutant can be easily converted to a negative ion by providing an extra electron. Many of the pollutants have dipolar charge distributions which facilitate electrical interactions with charges. If one of the pollutants becomes charged, it can attract other pollutants which are dipoles to form clusters of pollutants. Furthermore, charged clusters are responsive to electric and magnetic fields. For example, they can be separated from the rest of the flue gas by manipulating with such fields.

Abstract: In the field of immersion lithography, it is known to provide a liquid between an optical exposure system and a wafer carrying layers of photosensitive material to be irradiated with a pattern by the optical exposure system. However, bubbles are known to form or exist in the liquid, sometimes close to a surface of the wafer resulting in scattering of light emitted from the optical exposure system.

Abstract: A device for separating high mass to charge particles (M1) from low mass to charge particles (M2) in a plasma includes a cylindrical wall that surrounds a chamber and defines an axis. Rectangular shaped coils are mounted on the wall to establish a magnetic field, B0, in the chamber that is aligned substantially perpendicular to the axis and which rotates about the axis. Circularly shaped coils are provided to generate a time-constant, axially aligned magnetic field, Bz, in the chamber. Passive, ring-shaped electrodes are positioned at the ends of the wall and connected to resistors which are then grounded. The rotating magnetic field, B0, rotates the plasma in the axially aligned magnetic field, Bz, which in turn, induces a radially oriented electric field, Er, in the chamber. The crossed fields (i.e. Er×Bz) cause the particles, M1, to strike the wall while the particles, M2, transit through the chamber.
