Abstract: A charged particle buncher includes a series of spaced apart electrodes arranged to generate a shaped electric field. The series includes a first electrode, a last electrode and one- or more intermediate electrodes. The charged particle buncher includes a waveform device attached to the electrodes and configured to apply a periodic potential waveform to each electrode independently in a manner so as to form a quasi-electrostatic time varying potential gradient between adjacent electrodes and to cause spatial distribution of charged particles that form a plurality of nodes and antinodes. The nodes have a charged particle density and the antinodes have substantially no charged particle density, and the nodes and the antinodes are formed from a charged particle beam configured to hit the target.

Abstract: A medical packaging material based on a cellulosic nonwoven web which may be used in an oxidizing gas plasma sterilization environment. The material includes a cellulosic nonwoven web made up of fibers. From about 50 to 100 percent by weight of the fibers, based on the total weight of the fibers, are cellulosic fibers, and from 0 to about 50 percent by weight of the fibers, based on the total weight of the fibers, are noncellulosic fibers, such as glass wool and synthetic polymer fibers. In some embodiments, the cellulosic nonwoven web may be composed of 100 percent by weight of cellulosic fibers. The cellulosic nonwoven web includes a saturant which is present at a level of from about 50 to about 150 percent by weight, based on the dry weight of the fibers. The saturant includes a cellulosic fiber-protecting synthetic polymer having an effectively low permeability to hydrogen peroxide. For example, the cellulosic fiber-protecting synthetic polymer may have a water vapor transmission rate for a 2.

Abstract: A water purification system and a cleaning system and method for periodically flushing reverse osmosis water purification systems to rid the system of decontamination and other pollutants that build up during use. The system include a pair of containers in liquid communication, a first plurality of liquid conduits defining a looped path for passing liquid from the first container to a membrane and back to the first container, while a second plurality of liquid conduits defines a path for the liquid in the second container to the product side of the membrane.
