A paste for ceramic 3D shaping according to the present invention is a paste for ceramic 3D shaping containing a curable resin and inorganic particles, in which the inorganic particles contain ceramic particles and glass particles.

Filter media and filters, such as air filters, face masks, gas turbine and compressor air intake filters, panel filters and the like, are provided that include nanoparticles dispersed throughout at least a portion of the filter media. A filter media comprises a fiber substrate with a first surface and an opposing second surface. The filter media includes nanoparticles disposed within the fiber substrate at least between the first and second surfaces such that an area density of the nanoparticles decreases from the first surface towards the second surface. This density gradient formed by the nanoparticles through at least a portion of the substrate improves the performance characteristics of the filter. The nanoparticles increase the overall surface area within the fiber substrate, which may increase its filtration efficiency and allows for the capture of submicron contaminants without significantly compromising other factors, such as pressure drop or air flow through the filter.

A filter media suitable for use in filtering fluids is provided. The filter media comprises a first component, said first component having a core with an Al.sub.2O.sub.3 content of at least 10 wt % and a nanoalumina coating that at least partially coats the core.

A filter media suitable for use in filtering fluids is provided. The filter media comprises a filtration particle, said filtration particle having an Al.sub.2O.sub.3 content of from 15 wt % to 70 wt % and a SiO.sub.2 content of less than 70 wt % based on the weight of the particle.

Provided is a method for manufacturing an expandable artificial media for water treatment by recycling waste liquid crystal display (LCD) glass and waste bottle glass generated from waste electric and electronic products. Therefore, the objective of the present invention is to activate the efficiency of resource circulation and energy utilization, which are green technology, and to minimize the discharge of greenhouse gases and pollutants by artificially manufacturing media for water treatment, as a filtering technique for water pollution, wherein in the artificial media manufactured by a series of automation processes, waste LCD glass and waste bottle glass are recycled through foaming. That is, the present invention reproduces artificial media by mixing, with waste bottle glass, waste LCD glass generated during a process of manufacturing or processing glass for an LCD device, or waste LCD glass disposed of after using various electronic products including an LCD monitor, such that energy can be saved by lowering the foaming calcinations temperature of waste glass and waste recycling is attempted, thereby allowing the present invention to have an environmentally friendly property of preserving limited resources.

A method of making a media usable for instance in hydroponics. The method comprising mixing together three components, granulating the mixture and firing the granules formed, the first component is silica sand, the second component is mica granite sand, and the third component is a glass powder, with the firing taking place at a temperature such that the third component melts during firing.

Modular, stackable filter units are described. The units may contain particles of glass or other filtration material and may be used to cleanse debris-laden water of, for example, swimming pools or spas. They additionally may replace conventional pleated mesh filters and beds of sand if necessary or desired.

A method for preparing a crude oil solution for analysis, including adding water to a porous adsorbent to obtain a supported water substrate, having a plurality of water monolayers disposed on the porous adsorbent. The method further includes exposing the crude oil solution to the supported water substrate for a period of time; separating the supported water substrate from the crude oil solution; washing the supported water substrate with a water immiscible solvent to remove at least one hydrocarbon; displacing water from the plurality of water monolayers and the at least one interfacially active compound from the porous adsorbent with an alcohol and a co-solvent to obtain a displaced phase. The displaced phase can include the water, the at least one interfacially active compound, the alcohol, and the co-solvent. Finally, the method can include drying the displaced phase to isolate the at least one interfacially active compound.
