Optimizing arrythmia ablation
The heart is a muscular organ with four chambers designed to work efficiently, reliably, and continuously over a lifetime. The muscular walls of each chamber contract in a regulated sequence, pumping blood as required by the body while expending as […]
A photonic crystal the size of a single free space wavelength
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 […]
Detection of the reversal of magnetic moments in an antiferromagnet
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. […]
Polariton anomalous Hall effect in transition-metal dichalcogenides
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 […]
The protective effect of symmetry in entangled photonic states
One of the most mysterious features of quantum mechanics is that if two particles (or photons) interact at some point in time then the properties of these particles will remain connected at future times. A consequence of this is that […]
Enzybiotics, from phages to the inhaler.
Authors: Fernando González-Camacho, Bruno Corsini and Jose Yuste work at Centro Nacional de Microbiología, Instituto de Salud Carlos III (ISCIII) and Centro de Investigación Biomédica en Red de Enfermedades Respiratorias (CIBERES), Madrid, Spain.
In the age of bacteria resistant […]
Catalysis depends on the crystallographic plane of the catalyst
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 […]
Self-knotting bionic proteins
Author: Ivan Coluzza is an Ikerbasque Research Professor at CICbiomaGUNE
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 […]
The costs of going green
A tax on carbon emissions is an efficient way to make firms and consumers internalize the environmental costs due to climate change. However, there are many other aspects to consider in a transition from a fossil-fueled economy to a cleaner […]
Origin of the mysterious blue fluorescence of polymer carbon dots
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 […]
