An environmentally friendly wallpaper with weathering resistance and contaminating resistance includes a substrate layer and a silicone rubber layer composite and connected together. The wallpaper is prepared by a process of calendering and attaching-pressing for patterning-vulcanizating. The process is simple and the production can be constant, resulting in high efficiencies; the entire process is free of harmful substances and polluters. The prepared wallpaper is environmentally friendly and wholesome, and the wallpaper has superior properties such as weathering resistance, contaminating resistance, flame resistance, moisture resistance and mould resistance.

Provided herein is an oleophilic matrix comprising at least one polymer selected from the group consisting of a polydimethylsiloxane having micropillars; a microporous polydimethylsiloxane; and an ophthalmic-grade cellulose having an alumina-deposited surface. The matrixes can be used, for example, to remove an oil, such as a silicone oil, e.g., from a hydrophobic surface such as an intraocular lens, or from an aqueous environment.

The invention relates to a porous hydrogel matrix having substantially interconnected tunnel-shaped micropores with a three-dimensional configuration of an interconnected hollow tetrapod network. Such matrices may be used to entrap motile cells that migrate into the micropores of said matrix. The matrices of the invention are formed by a method comprising the steps of providing a solution of a hydrogel-forming material, providing a template material with a three-dimensional configuration corresponding to the negative configuration of the desired interconnected porous structure of the hydrogel material, said template material comprising interconnected zinc oxide tetrapod (t-ZnO) networks, casting the solution of hydrogel-forming material onto the template and removing the template material from the hydrogel material by acid hydrolysis of the template material.

The present invention provides a separating medium including porous resin particles which has a sufficient pore diameter suitable for liquid chromatography applications and which has high strength, is reduced in pressure loss during liquid passing, has the excellent property of separating a desired substance, and has low nonspecific adsorption properties. The separating medium of the invention is a separating medium obtained by treating porous epoxy resin particles and having an average pore diameter of 10 to 2,000 nm, or a separating medium obtained by treating porous epoxy resin particles and having a water content of 50% or higher.

The present invention provides novel chromatographic materials, e.g., for chromatographic separations, processes for its preparation and separations devices containing the chromatographic material; separations devices, chromatographic columns and kits comprising the same; and methods for the preparation thereof. The chromatographic materials of the invention are high purity chromatographic materials comprising a chromatographic surface wherein the chromatographic surface comprises a covalently-bonded surface group and one or more ionizable modifier.

The present disclosure is directed to a desulphurization agent for removing sulphurous species from a diluent or process stream, and a use of such agent. In some examples, the agent may include a compound of manganese, pore forming particles and a compound of copper. The agent may be introduced into or mixed with the diluent or process stream to effectuate removal of sulphurous species from the diluent or process stream.

A method for calcining diatomaceous earth may include adding at least one lattice interfering agent to the diatomaceous earth to form a composite material. The method may further include heating the composite material at a temperature of at least about 800 C. for at least about 15 minutes to form an at least partially calcined composite material. The at least one lattice interfering agent may include at least one cation of at least one of aluminum and titanium. A diatomaceous earth product may include the at least partially calcined composite material formed from the above-noted method for calcining diatomaceous earth. A filter aid may include the diatomaceous earth product.

A self-regenerating chitosan based filter medium for disinfecting and purifying organic pollutants and other pollutants in a gas or liquid is disclosed herein. Porosity and surface charge of said filter medium is manipulative/tunable by varying one or more of the following parameter(s): concentration of chitosan, crosslinking density, amount of copolymers and additives, freezing temperature, freezing profile, and/or types of crosslinker used. The present filter medium is capable of self-regenerating under exposure to ultra-violet light for sufficient time and removing over 90% of the pollutants from each influent flowing through the filter medium.

A porous material including polymerized units containing pores is provided, which can be employed for desalination applications. Each of the units includes at least one aromatic amino group and at least one hydroxyl group. The aromatic amino groups and the hydroxyl groups are arranged on surfaces of the pores in geometries configured to capture sodium chloride from an aqueous environment. The porous material can be provided as particles or a sponge. The porous material can be manufactured from a solution including monomers, a porogen, and an initiator by a polymerization process. The porous material can be reused after a desalination process by treatment with deionized water. A steam generation apparatus can be employed to facilitate removal of sodium chloride from the porous material in which sodium chloride is captured.
