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 mask for preventing infection by a virus is provided. The mask includes a coated substrate having a breathing resistance (95 L/min, EN 149:2001) of about 6 mbar or less and a water droplet absorption time of less than about 5 seconds. The coated substrate includes a non-woven fabric having a weight of about 120 g/m.sup.2 or less according to ASTM D3776, and mineral oxide particles, iron oxide particles, or both, coupled to at least a portion of the non-woven fabric.

The invention relates to a bioactive composition for killing cells, comprising at least a first and a second half cell, the half cells being in electrically conductive contact with each other at least by their respective surfaces such that short-circuit elements are generated in the presence of water and oxygen. According to the invention the first half cell comprises at least one semiconductive compound of at least one transition metal element, which exhibits multiple oxidation states and allows a change of the oxidation states by means of catalytically active centers, so that oxygen is reduced and active oxygen species are produced at the first half cell, and wherein the second half cell comprises at least one electrically conductive silver semiconductor which absorbs electrons emitted by the cells or organic material. By means of particles coated with the composition according to the invention, for example, E. coli bacteria can be effectively and reliably killed with both a ruthenium oxide/silver chloride version (a-c) and a ruthenium oxide/silver sulfide version (d-f).

An insect trap includes an exothermic body, and a layered body. The exothermic body is configured to include exothermic powder enclosed in an inner bag that is air permeable; the exothermic powder contains iron powder that releases heat when oxidized. The layered body is configured with layers of plate-like elements and includes gaps as a pathway of entry for an insect pest. A housing space to house the exothermic body is arranged inside the layered body. The layered body and the inner bag are made of a biodegradable raw material.
