COMPOSITE FOR OIL-WATER SEPARATION, SYNTHESIS METHODS AND APPLICATIONS OF SAME
Certain aspects of the invention relate to a composite for oil-water separation, synthesis methods and applications of the same. The composite includes a nanostructured powder or porous material having surfaces with nanoscale features, formed from a pristine powder or porous material by a surface nanostructuring process, and single or multilayers of a low surface energy oligomer or polymer coated on the surfaces of the nanostructured powder or porous material. The composite is hydrophobic (or superhydrophobic) and oleophilic (or superoleophilic) operably repelling water and absorbing oil, or oleophobic (or superoleophobic) and hydrophilic (or superhydrophilic) operably repelling oil and absorbing water.

Multimodal chromatographic media for protein separation
A chromatographic media for separating bio-polymers, the chromatographic media having cationic exchange properties and anionic exchange properties, the chromatographic media comprising: (a) non-porous substrate particles including an organic polymer, the substrate particles having a neutral hydrophilic layer at a surface of the non-porous substrate particles, in which the neutral hydrophilic layer is configured to reduce a binding of the bio-polymers directly to the non-porous substrate particles compared to a binding of the bio-polymer to the non-porous substrate particles without the neutral hydrophilic layer; (b) a charged first ion exchange layer bound to the substrate particles on top of the hydrophilic layer, the first ion exchange layer comprising first ion exchange groups; and (c) a charged second ion exchange layer bound to the substrate particles on top of the first ion exchange layer.
Porous material and devices for performing separations, filtrations, and catalysis and EK pumps, and methods of making and using the same
Embodiments of the present invention are directed to a porous monolith polymeric composition having utility in catalysis, chromatography, filtration, and electro-kinetic pumps, devices incorporating such composition and methods of making and using such monoliths. In some embodiments the monoliths can include a skeletal core having a substantially homogeneous polymeric composition of two or more organic silane monomers and pores that define an interstitial volume in the skeletal core. The pores can include macropores and less than 5% of the interstitial volume can be mesopores. Such monoliths can, in some embodiments, be disposed in a housing having at least one wall that defines a chamber such that all fluid flowing into the chamber passes through the pores of the monolith.
BIO-DEGRADABLE POROUS BONDED-GRAIN MONOLITHIC CO2 SCRUBBER FOR RESPIRATION DEVICES
The present disclosure relates to a biodegradable porous bonded-grain monolithic CO2 scrubber for respiration devices. The scrubber comprises a monolithic body of bonded grains, including calcium hydroxide, sodium hydroxide, lithium hydroxide, and potassium hydroxide, to act as CO2 absorbents. The body features enclosed gas passages facilitating gas flow and CO2 absorption. The grains are bonded via adhesion, powder polymer, or heat sintering, and the structure includes hydrophobic additives to reduce caustic solution formation. The scrubber can be manufactured through extrusion or additive manufacturing, with various passage shapes and sizes. The monolithic body may include biodegradable polymers for environmentally sound disposal.
