Copper oxide, the kind that forms on pieces of copper when you heat them with a flame, is very fascinating stuff. Besides being usable for other things such as making photo sensors, thermistors, pressure sensors and diodes, it can also be used to make an impressive homemade thermoelectric junction capable of producing hundreds of millivolts when heated with a flame.

Basic copper(II) carbonate, when heated above 250 °C, produces a black oxide if a dense carbonate is employed; a brown material is produced when the light and fluffy carbonate is used. An alkali-free oxide can be prepared by ignition of copper(II) carbonate produced from ammonium carbonate and a copper(II) salt solution.

A platform technology has been developed that permanently introduces copper oxide into polymeric materials, conferring them with potent biocidal properties. Methodology/principal findings: We demonstrate that impregnation of copper oxide into respiratory protective face masks endows them with potent biocidal properties in addition to their inherent filtration properties.
