Abstract: Systems and methods for cleansing blood are disclosed herein. The methods include acoustically separating undesirable particles bound to capture particles from formed elements of whole blood. After introducing the capture particles to whole blood containing undesirable particles, the whole blood and capture particles are flowed through a microfluidic separation channel. At least one bulk acoustic transducer is attached to the microfluidic separation channel. A standing acoustic wave, imparted on the channel and its contents by the bulk acoustic transducer, drives the formed elements and undesirable particles bound to capture particles to specific aggregation axes. After aggregating the particles, the formed elements exit the separation channel through a first outlet and are returned to the patient. The undesirable particles, bound to the capture particles, exit through a second outlet and can be discarded to saved for later study.

Abstract: A process for treatment of water. Hardness and non-hydroxide alkalinity are removed from feedwaters to an extent sufficient to avoid scaling when concentrated. Sparingly ionizable components in the feedwater are urged toward increased ionization by increasing the pH of the feedwater. In this manner, species such as silica become highly ionized, and (a) their rejection by membranes used in the process is significantly increased, and (b) their solubility in the reject stream from the membrane process is significantly increased. Sparingly ionized species such as boron, silica, and TOC are highly rejected. Recovery ratios of ninety percent (90%) or higher are achievable with many feedwaters, while simultaneously achieving a substantial reduction in cleaning frequency of membranes used in the process.

Abstract: The invention relates to improved methods of grafting polymer extenders onto porous substrates having diffusive pores, such as those used in protein separations, without filing the diffusive pores of the substrate, and restricting diffusion there through. By changing the grafting conditions and/or monomer composition(s) the resulting porous substrates having polymer extenders grafted thereto have increased protein binding capacity and resin selectivity, thereby enhancing the protein separation effectiveness of the substrate. The grafted polymer extenders provide the substrate with significant binding capacity at higher conductivity. The invention also relates to kits, and methods of using and grafting polymer extenders on porous resin substrates having diffusive pores.

Abstract: Polymers including pendent hydrophobic groups and pendent proton transfer groups are shown to form nanostructured films exhibiting greatly increased proton conductivity compared with films prepared from corresponding polymers lacking hydrophobic groups. The polymers can include repeating units each of which has both a hydrophobic group and a proton transfer group. Alternatively, the polymers can be the product of copolymerizing a first monomer with at least one hydrophobic group and a second monomer with at least one proton transfer group. The polymers are useful for the preparation of fuel cell proton exchange membranes.
