Embodiments of the present disclosure generally relate to coated substrates having, e.g., anti-viral properties, to articles including the coated substrates, and to processes for making such coated substrates and articles. In an embodiment, a coated substrate is provided. The coated substrate includes a substrate having a weight of about 120 g/m.sup.2 or less according to ASTM D3776, mineral oxide particles, iron oxide particles, or both, coupled to at least a portion of the substrate wherein the coated substrate has a breathing resistance (95 L/min, EN 149:2001) of about 6 mbar or less.

A filter medium layer includes filter media configured to capture suspended solids contained in a liquid to be treated and filtering aids configured to allow the suspended solids contained in the liquid to be treated to pass through the filtering aids. The filter media and the filtering aids are mixed together and the liquid to be treated is filtered by being passed through the filter media and the filtering aids as mixed together. A filter device includes the filter medium layer and a filter tank configured to accommodate the filter medium layer.

Processes and systems for recovering products from a corn fermentation mash. In one example, a process for recovering products from a corn fermentation mash can include separating ethanol from a fermentation mash to produce a whole stillage. The fermentation mash can be derived from a ground corn product milled from a plurality of corn pieces. The plurality of corn pieces can include whole corn kernels, fragmented corn kernels, size-reduced corn kernels, milled corn kernels, or a mixture thereof. Greater than 25 wt % of the ground corn product can have a particle size of greater than 105 μm and greater than 80 wt % of the ground corn product can have a particle size of 425 μm or less, as measured according to AOAC 965.22-1966. The process can also include separating the whole stillage to produce a fiber rich portion and a filtrate.

Electret webs include a thermoplastic resin and a charge-enhancing additive. The charge-enhancing additive is a divalent metal-containing substituted-mercaptobenzimidazolate salt. The electret webs may be a non-woven fibrous web or a film. The electret webs are suitable for use as filter media.

Provided is a polycarbonate resin powder, including a polycarbonate-polyorganosiloxane copolymer, in which an amount of particles each having a particle diameter of 300 μm or less in an entirety of the powder is 60 mass % or less.

A humidification filter, in one aspect, includes at least one of natural fiber and regenerated fiber mixed with a hydrophobic synthetic fiber.

A high-efficient particulate air filter assembly including a high efficient particulate air filter for filtering the intake air as it enters an air purifying system is provided. The air filter assembly can further include a housing configured for use in an air purification system; a first prefilter positioned in the housing upstream from the particulate air filter; and an electrostatically charged substrate positioned in the housing downstream from the particulate air filter. The air filter assembly can further include a second prefilter having a paper layer; a carbon layer; a zeolite layer; a mesh layer; and a foam layer.
