You can read this article because I have used photonics in order to make it possible. It may sound futuristic, but photonics is a technology we use, one way or the other, on a daily basis. Photonic devices are analogous […]

Some metals, alloys and transition-element salts exhibit a form of magnetism called antiferromagnetism. This occurs below a certain temperature, named after Louis Néel, when an ordered array of atomic magnetic moments spontaneously forms in which alternate moments have opposite directions. […]

Two-dimensional materials, such as transition-metal dichalcogenides embedded in optical cavities, stand out as an excellent platform where strong light-matter interactions can be studied. Moreover, their band structures bring about nontrivial topological features, including the possibility of inducing some really […]

A catalyst is a substance that increases the rate of a chemical reaction without itself undergoing any permanent chemical change. As the catalyst itself takes part in the reaction it may undergo a physical change. Hence, if catalysts take […]

Some heteropolymers can be designed to spontaneously self-assemble in complex pre-determined knotted structures. In the past, we referred to such designable heteropolymers as “bionic proteins”. Here we present an extensive […]

A quantum dot is a nanometric crystalline structure of semiconductor materials. In a quatum dot electrons are confined in a region of space, thus creating a well defined structure of energy levels that depends very much on the size and […]

In the transition from a petrol-based society to a one based on bio-renewable resources, the replacement of aromatic chemicals is one of the most challenging issues. Nowadays, around 40% of the bulk chemicals belong to the aromatic category, and a […]

Imagine a military regiment in formation. That we will call symmetry. Now imagine the same regiment when it is dismissed by the commanding officer: at once the soldiers disperse and tend to form domains (groups) or pairs. Hence, we can […]

Few materials have drawn as much attention as graphene, it fascinating attributes such as one-atom thickness and relativistic electrons, and its technological properties […]

Common glass, used in windows or bottles, for example, is made by heating a mixture of calcium oxide (lime), sodium carbonate (soda), and silicon (IV) oxide (sand), resulting in a calcium silicate. This silicate is not a crystal but a […]
