If a nucleus has a nonzero spin, it behaves as a small magnet. Therefore, in an external magnetic field, the nuclear magnetic moment vector precesses about the field direction but only certain otientations are allowed by quantum rules. Thus, for […]

The scattering of conduction electrons in metals owing to impurities with magnetic moments is known as the Kondo effect, after Jun Kondo, who analysed the phenomenon in 1964. This scattering increases the electrical resistance and has the consequence that, in […]

The Diagnostic and Statistical Manual of Mental Disorders, 5th edition (DSM-5) includes sensory alterations as one of the four characteristics of restricted / repetitive behavior of people with autism spectrum disorder (ASD). It defines this symptom characteristic as a «hyper- […]

Many aromatic compounds can be made into organic semiconductors by doping them with a substance such as iodine, thereby producing mobile carriers of electric charge. This is analogous to the doping of silicon in an ordinary semiconductor. The benefits of […]

First of all, I don’t want to mean that a neuron was found in space, but that similarly to the grid cells found by Nobel laureate May-Britt Moser and colleagues another cell type named object-vector cell has been found -also […]

Author: Daniel Pérez is currently a postdoctoral researcher at Wallenberg Centre for Quantum Technology, Sweden.
Last February I published my first scientific article as principal author in Physical Review B . This article summarizes a big part of my work […]

Since the discovery of graphene, a wide diversity of atomic-layer-thick, two-dimensional (2D) materials with varied properties have emerged. Of particular interest are those that exhibit semiconducting behavior, such as hexagonal boron nitride (hBN). hBN is isoelectronic to graphene and has […]

The computer metaphor draws an analogy between the mind as software and the brain as hardware. In this metaphor, the focus of discussions is usually on the software part, taking for granted that the brain, or the whole nervous […]

On our unique planet, life evolved under the pressure of natural selection. The evolution theory of Darwin demonstrates the incredible plasticity of the living organism. For millions of years, living […]

The way a particular reaction proceeds, described in terms of the steps involved, is called mechanism. The study of organic chemistry is, to a great extent, the study of reaction mechanisms and textbooks content both their description and their applications. […]
