Abstract: Polymeric compositions that include a polymer matrix and a germicidal additive dispersed in the polymer matrix are described. The germicidal additive includes a metal complexed cyanurate composition having a general formula of Ax[My(C3O3N3Cl2)z], where A is a counterion, x, y, and z are each independently 1 to 6, and M is a transition metal.

Abstract: Disclosed is a method of preparing a polymer composite component, wherein the method comprises uniformly dispersing glycerol and metal ions on a polymer powder to create a polymer composite powder, extruding the polymer composite powder at a temperature of at least 80° C., thereby converting a portion of the metal ions to metal atoms, and then forming the component from the extruded polymer composite. The component can be a thin film, to be applies to surfaces to increase antimicrobial properties.

Abstract: A method of manufacturing an article includes melt-mixing a first polymer with a second polymer and optionally an additive to form a thermoplastic composition, the first polymer having a first melting point or a first glass transition temperature T1, the second polymer having a second melting point or a second glass transition temperature T2 that is 30° C. to 150° C. higher than T1: and forming the article from the thermoplastic composition at a temperature between T1 and T2, such as via sheet extrusion, thermoforming, pipe extrusion, extrusion molding, injection molding, extrusion molding, blow molding, compression molding, or additive manufacturing. The first polymer and the second polymer can have a volume ratio of 75:25 to 35:65 with a co-continuous morphology in the thermoplastic composition, with the second polymer providing a network for containing a melt of the first polymer.

Abstract: The present invention relates to a material composition comprising: (i) a polyester selected from polyethylene terephthalate, polybutylene terephthalate, or mixtures thereof; and (ii) ?1.0 and ?30.0 vol % of aluminium particles and to a shaped object comprising a material composition comprising such material composition. Such shaped object does demonstrate the desirable mechanical impact properties, and also demonstrates the desirable electromagnetic shielding, electrical conductivity, and thermal conductivity, given its high loading of aluminium.

Abstract: Disclosed are heterostructured silica catalysts (modified Haider heterostructured silica) and methods of their use and preparation. The heterostructured silica catalysts include a transition metal, an alkaline earth metal oxide, and silica, wherein the transition metal, the alkaline earth metal from the metal oxide thereof, and silicon (Si) from silica are each present in the crystal lattice structure of the catalyst. The catalyst can have application in, e.g., the hydrogenation of carbon monoxide.

Abstract: A bimetallic catalyst for the production of 1,3-butadiene from n-butane, methods of making, uses thereof are described. The catalyst can include a supported catalytic bimetallic material on a silica support that includes an iron metal or oxide thereof dispersed throughout a silica-alkaline earth metal oxide support or in the core of the silica alkaline earth metal oxide framework.

Abstract: Biocompatible titanium base alloys for medical devices which are intended to remain on or in a living human being for an extended period of time, such as surgical and medical implants. The alloys are free from toxic elements such as Al, Ni, Co, Fe, Cr, Mo, and W. They are quaternary alloys of Ti with between about 2.5% up to 13% Zr, about 20% to about 40% Nb, about 4.5% to about 25% Ta, all percentages being by weight, the balance being Ti and the total of Ta plus Nb being between about 35% and 52% by weight. The ration of Nb/Ta is between 2 and 13. These alloys may also contain limited amounts of non-toxic interstitial elements, such as C, N, and O. The relative proportions of Ti, Zr, Ta, and Nb are such that the modulus of elasticity is below 65 GPa.
