Tetrapyrroles,“the pigments of life”,are key molecules for the metabolism of living organisms, supporting functions of vital importance such as electron transport, light-harvesting and oxygen reduction. Within this family of compounds, porphyrins are organic pigments characterized by the possesion of a cyclic group of four linked nitrogen-containing rings called porphyrin, the nitrogen atoms of which are […]

Terahertz (THz) radiation is all around us. For example, this page emits blackbody radiation mainly in the THz region (broadly from 0.3 THz to 30 THz). Because terahertz radiation begins at a wavelength of around one millimeter and proceeds into shorter wavelengths, it is sometimes known as the submillimeter band, and its radiation as submillimeter […]

Real life is sometimes very different from laboratory settings. Take superconductivity, for example. In order to reach, it you either need extremely low temperatures, extremely high pressures or a combination of both; something that makes very difficult to conceive an everyday application out of a laboratory. Something similar happens with other new materials, but in […]

Back in 1929, theoretical physicist Hermann Weyl predicted the existence of a new elementary particle with intriguing properties. Specifically, it would be massless (like a photon), have half-integer spin (like an electron) and exist in two mirror-image versions (like left- and right-handed gloves)—a property known as chirality. Imagine there exist a material in which an […]

In spintronics, new memory and logic devices are being developed based on the use of spins of nuclei, atoms, or molecules, instead of electronic charges. The main advantages are an improved energy efficiency and speed of operation to store and process information. The ability of organic molecules to maintain magnetic multistability in nanoscale junctions will […]

A nanoantenna with balanced electric and magnetic dipole moments exhibits a directive radiation pattern with zero backscattering. This is known as the first Kerker condition after Kerker, Wang, and Giles, who predicted in 1983 that, under plane wave illumination, magnetic spheres with equal relative permittivity and permeability radiate no light in the backscattering direction. They […]
