A desalination device includes a container, first and second electrodes, an anion exchange membrane (AEM), and a power source. The container contains saline water that has an elevated concentration of dissolved salts. The AEM separates the container into first and second compartments into which the first and second electrodes, respectively, are arranged. The AEM has a continuous porous structure and a plurality of negatively-charged oxygen functional groups coupled to the porous structure. The power source is configured to selectively apply a voltage to one of the first and second electrodes. The AEM has a selective permeability when the voltage is applied such that cations in the saline water solution have a first diffusion rate d.sub.1 therethrough and anions in the saline water solution have a second diffusion rate d.sub.2 therethrough. The first diffusion rate d.sub.1 is less than the second diffusion rate d.sub.2 and greater than or equal to zero.

Disclosed is a preparation method for charge reversal and reversibly crosslinked redox-sensitive nanomicelles, falling within the technical field of biomedical materials. The method comprises: synthesizing thiocinamide from lipoic acid and ethylenediamine under an N,N-carbonyl diimidazole catalyst; and polymerizing thiocinamide, polyethylene glycol diglycidyl ether and lysine through a nucleophilic addition mechanism to prepare a poly(lysine-co-polyethylene glycol diglycidyl ether-co-thiocinamide) terpolymer. The micelle is endowed with excellent anti-protein nonspecific adsorption and enhanced cell uptake property through a self-assembly and protonation/deprotonation action; and a disulfide bond in lipoyl may form a linear polydisulfide structure under the action of 1,4-dithiothreitol, so that a micelle core is crosslinked, and a crosslinked structure is destroyed in the cell under a redox condition, and controlled release of a drug can be achieved. The Nanomicelle of the present invention is expected to be a carrier of drugs for treating cancers.

A catalyst complex for catalysis of degradation of a polymer material is described. Said complex comprises a magnetic particulate body containing iron oxide at its surface with an average diameter of 150-450 nm, and a plurality of catalytic groups grafted onto the iron oxide surface of the magnetic particulate body, which catalytic groups comprise a bridging moiety and a catalyst entity, wherein the bridging moiety comprises a functional group for adhesion or bonding to the iron oxide surface and a linking group towards the catalyst entity, and wherein the catalyst entity comprises a positively charged aromatic heterocycle moiety, and a negatively charged moiety for balancing the positively charged aromatic moiety.

Nanostructured polyelectrolyte bilayers deposited by Layer-by-Layer deposition on nanoporous membranes can be selectively crosslinked to modify the polyelectrolyte charge density and control ionic selectivity independent of ionic conductivity. For example, the polyelectrolyte bilayer can comprise a cationic polymer layer, such as poly(ethyleneimine), and an anionic polymer layer, such as poly(acrylic acid). Increasing the number of bilayers increases the cation selectivity when the poly(ethyleneimine) layer is crosslinked with glutaraldehyde. Crosslinking the membranes also increases the chemical and mechanical strength of the polyelectrolyte films. This controllable and inexpensive method can be used to create ion-selective and mechanically robust membranes on porous supports for a wide range of applications.

The various embodiments of the present invention disclose an peroxide-vulcanised TPVs based on Hevea Brasiliensis natural rubber, polypropylene and solid sulfonic acid doped polyaniline [PAni.DBSA] with useful electrical conductivities (up to about 2.10.2 S/cm] can be produced by using an internal mixer. The peroxide-vulcanised TPVs exhibit useful physical properties and also possess a reasonable good electromagnetic interferences shielding effectiveness. These peroxide-vulcanised TPVs could be recycled up to 4 times without significant loss of their EMI SE, electrical and physical properties. As a result, they have good potential to be used for manufacturing any EMI shielding products, such as EMI shielding seals and gaskets.

A low density foam material and methods for making such, comprising self-assembled graphene oxide in foam is described having high performance acoustic absorption as well as increased moisture insulation and fire-retardant properties. The graphene oxide material is inserted or distributed within openings of open cell/pore foam material resulting in a novel foam material that has increased acoustic absorption properties.

Antibacterial coatings and methods of making the antibacterial coatings are described herein. A first branched polyethylenimine (BPEI) layer is formed and a first glyoxal layer is formed on a surface of the BPEI layer. The first BPEI layer and the first glyoxal layer are cured to form a crosslinked BPEI coating. The first BPEI layer can be modified with superhydrophobic moieties, superhydrophilic moieties, or negatively charged moieties to increase the antifouling characteristics of the coating. The first BPEI layer can be modified with contact-killing bactericidal moieties to increase the bactericidal characteristics of the coating.
