Disclosed herein is a nanostructured material comprising defective carbon nanotubes chosen from impregnated, functionalized, doped, charged, coated, and irradiated nanotubes, and combinations thereof. The defective carbon nanotubes contain a defect which is a lattice distortion in at least one carbon ring. Also disclosed is a method of purifying fluids, such as liquids, including water, as well as gases, including the air using, this nanostructured material.

A plasma concentrator of this invention having a concentrator chamber, concentrator gel beads, a filter, and an agitator. The agitator has agitator blades extending outwardly from the lower end. The agitator end is positioned in the concentrator chamber and supported for rotation about its central axis and for reciprocal movement along its central axis. The concentrator has a top with an upper opening through which the upper end of the actuator stem extends, and a lower opening in which the filter is positioned. The concentrator chamber can have a cylindrical inner wall, and the agitator blades can have an outer edge in close proximity to the inner wall with the space between the outer edge and the inner wall being less than the diameter of the gel beads. The filter is selected to block effective flow of plasma therethrough under ambient gravity conditions and permit plasma and plasma concentrate flow therethrough under centrifugal forces of the separation gravity. The method concentrates plasma by removing water without significantly denaturing the fibrinogen in the plasma. The plasma is introduced into a concentration chamber containing a plurality of dehydrated concentrator gel beads and an agitator. Then water is removed from the plasma while stirring the beads to reduce plasma polarization and breaking up clumps of beads that form during the agitation. Then centrifugal force can be applied to the concentrated plasma in an amount sufficient to separate a substantial portion of the plasma concentrate from the beads.

The invention relates to a method of distributing a liquid in the fluid bed of an up-flow or a down-flow fluid bed reactor. The invention provides efficient distribution and plug flow like fluid flow through the fluid bed where turbulence and / or back-mixing of the fluid are minimized. In accordance with the invention a fluid bed system for use in treating a fluid by contacting the fluid with a solid phase media is provided and the system includes a reactor chamber adapted to contain the solid phase media and at least one fluid distribution means adapted to distribute and / or deliver the fluid to be treated among the particles of the medium.

Devices, systems, and methods for depleting fluids of immunoglobulins and leukocytes are disclosed.

A system and method for washing engines and for collecting and treating the waste water from engine washing operations. The system includes a collecting device for collecting waste liquid during a washing operation of the engine and a treatment device for treating waste liquid collected during the washing operation. The system may be advantageously arranged on a mobile cart having a chassis provided with wheels. The mobile cart also includes an adjusting device for adjusting the vertical position of liquid separating and collecting components relative to the engine.

The PRP separator-concentrator of this invention is suitable for office use or emergency use for trauma victims. The PRP separator comprises a motorized centrifugal separation assembly, and a concentrator assembly. The centrifugal separator assembly comprises a centrifugal drum separator that includes an erythrocyte capture module and a motor having a drive axis connected to the centrifugal drum separator. The concentrator assembly comprises a water-removal module for preparing PRP concentrate. The centrifugal drum separator has an erythrocyte trap. The water removal module can be a syringe device with water absorbing beads or it can be a pump-hollow fiber cartridge assembly. The hollow fibers are membranes with pores that allow the flow of water through the fiber membrane while excluding flow of clotting factors useful for sealing and adhering tissue and growth factors helpful for healing while avoiding activation of platelets and disruption of any trace erythrocytes present in the PRP.
