A composition for treating water including an organic soil amendment and having ions bound thereto is beneficial to aid in the removal of aqueous contaminants, such as phosphate, other phosphorus containing compounds, arsenic, arsenic containing compounds, fluorides, and PFAS from water. In these compositions the ions include rare earth cations, iron cations, and mixtures thereof. There are also methods for making these soil amendment compositions, as well as methods for using these compositions to effectively remove contaminants from water.

A coating composition or a polymer composition containing UV/HEV absorbing material has a ratio of electromagnetic radiation absorption at 450 nm to that at 320 nm of greater than 5%, preferably greater than 10% and more preferably greater than 20%. An additive for incorporation into a coating, or for incorporation into a polymer, comprises nanoparticles of cerium oxide in combination with at least one other metal oxide. The additive is configured so that the coating when applied to a surface, or the polymer, has a total absorption of at least 10% of electromagnetic radiation in a wavelength band between 400 nm and 500 nm. A wood coating comprising the additive, having a total absorption of at least 10% of electromagnetic radiation in a wavelength band between 400 nm and 500 nm, is also disclosed.

Provided is a cooking item, at least one of the surfaces of which has a fluorocarbon coating including rare earth oxide fillers. The use of a composition including a fluorocarbon resin and rare earth oxide fillers makes it possible to obtain coatings, the mechanical properties of which (particularly in terms of hardness and resistance to abrasion) are reinforced without any breakdown in the non-stick properties of said composition. Also provided is a method for manufacturing such a cooking item.

This disclosure relates to novel blended compositions for biological contaminant removal containing a particulate oxide composition and silver zinc zeolite. The particulate oxide composition is a mixed oxide of at least cerium and trivalent dopant. These blended compositions can be used as antimicrobial/antibacterial/antiviral agents. As such, this disclosure also relates to the use of these blended compositions for biological contaminant removal. The blended compositions have uses for removing bacteria, viruses, protozoa (e.g., amoebae), fungi (e.g., mold), algae, yeast, and the like. In particular, these blended compositions can be used in methods for treating fluids, including liquids or air, and solid surfaces through contact.

A silicone rubber composition is provided comprising (A) an alkenyl-containing organopolysiloxane, (B) reinforcing silica, (C) an inorganic particle-polysiloxane composite comprising inorganic nanoparticles having a polysiloxane containing SiR.sup.2R.sup.3O.sub.2/2 and SiR.sup.4R.sup.5R.sup.6O.sub.1/2 units grafted to their surface, and (D) a curing agent.
