摘要： A bi-layered superhydrophobic membrane includes top and base layers formed from polypropylene. The bi-layered superhydrophobic membrane can have a thickness ranging from about 100 μm to about 1 mm. When subjected to oil-water emulsion separations, the superhydrophobic membrane can achieve an organic solvent flux of 14,000 Lm−2h−1 with a 96% water rejection. The bi-layered superhydrophobic membrane can be effectively used for water filtration, providing both selectivity and permeability, while offering an eco-friendly solution for reuse of polypropylene plastic waste.

摘要： A membrane includes a polysulfone-based support, a polydopamine (PDA) layer disposed on a surface of the polysulfone-based support, and a silver/polydopamine (Ag/PDA) composite layer disposed on a surface of the polydopamine layer. The polysulfone-based support has a pore size of up to 600 nanometers (nm). The Ag/PDA composite layer contains core-shell structure particles and spherical particles. The core-shell structure particles have a silver nanoparticle core and a polydopamine shell. The spherical particles are silver-decorated polydopamine particles. The membrane can at least partially separate an Erichrome Black T (EBT) dye from an EBT dye/salt containing mixture by rejecting the EBT dye and allowing the EBT dye/salt containing mixture to pass through the membrane.

摘要： A method of assessing a membrane, including calculating fluid dynamic characteristics of at least one of a membrane and a material to be passed through the membrane, where the material comprises particles; obtaining characteristic of at least one force acting on the particles of the material to be passed through the membrane due to the interaction between the particles and the membrane, the at least one force being an intermolecular force; combining the calculated fluid dynamic characteristic and the obtained characteristics to assess the flow of the material through the membrane; and optimizing at least one characteristics of the membrane in relation to the material. The membrane includes a plurality of rows and a plurality of teardrop structures arranged in the plurality of rows. The teardrop structures in each row are arranged at substantially the same angle with respect to an anticipated direction of flow through the membrane.

摘要： The objective of the present invention is to provide a porous ultra-thin polymer film, and a method for producing said porous ultra-thin polymer film. The present invention provides a porous ultra-thin polymer film with a film thickness of 10 nm-1000 nm. In addition, the present invention provides a method for producing a porous ultra-thin polymer film, comprising the steps of: dissolving two types of mutually-immiscible polymers in a first solvent in an arbitrary proportion to obtain a solution; applying the solution onto a substrate and then removing the first solvent from the solution applied onto the substrate to obtain a phase-separated ultra-thin polymer film that has been phase-separated into a sea-island structure; and immersing the ultra-thin polymer film in a second solvent which is a good solvent for the polymer of the island parts but a poor solvent for a polymer other than the island parts to remove the island parts, thereby obtaining a porous ultra-thin polymer film.

摘要： The present disclosure describes a strategy to create self-healing, slippery liquid-infused porous surfaces (SLIPS). Roughened (e.g., porous) surfaces can be utilized to lock in place a lubricating fluid, referred to herein as Liquid B to repel a wide range of materials, referred to herein as Object A (Solid A or Liquid A). SLIPS outperforms other conventional surfaces in its capability to repel various simple and complex liquids (water, hydrocarbons, crude oil and blood), maintain low-contact-angle hysteresis (

摘要： A filtration cell (10) for a biological sample having an outer housing (12) defining a first chamber and an inner housing (14) defining a second chamber is disclosed. The inner housing is disposed within the first chamber and rotatable with respect to the outer housing and at least a portion of the inner housing includes a filtration membrane (52). Upon rotation of the inner housing, a first portion of the biological sample passes from the first chamber into the second chamber and a second portion of the biological sample is restrained in the first chamber. Alternatively, the filtration cell may also include a rotation element disposed in the inner housing. Upon rotation of the rotation element with respect to the inner housing, a first portion of the biological sample to passes from the second chamber into the first chamber and a second portion of the biological sample is restrained in the second chamber.
