111 skos:definition Metal-organic frameworks (MOFs) are a class of crystalline materials that consist of coordination bonds between transition-metal cations and multidentate organic linkers. The structure of MOFs is characterized by an open framework that can be porous (porous materials). MOFs can be used for gas storage, purification and separation, as well catalysis and sensing applications.

121 skos:definition Photocatalysis is a type of catalysis that results in the modification of the rate of a photoreaction - a chemical reaction that involves the absorption of light by one or more reacting species - by adding substances (catalysts) that participate in the chemical reaction without being consumed.

130 skos:definition Porous materials are materials with pores (cavities, channels or interstices). The characteristics of a porous material vary depending on the size, arrangement and shape of the pores, as well as the porosity (the ratio of the total pore volume relative to the apparent volume of the material) and composition of the material itself.

140 skos:definition Solar cells are devices for converting sunlight into electricity. Their primary element is often a semiconductor which absorbs light to produce carriers of electrical charge. An applied electric field can then sweep these carriers out of the semiconductor, thus producing an electrical current.

By exploiting this coupling between thermal and electrical properties, thermoelectric devices can be made that carry heat from a cold to a hot side (refrigeration) or that generate electricity from heat flows.
