Atom scattering at low energies has a long history as a useful probe of surface properties. The most common atomic projectiles are helium atoms formed into a monoenergetic beam directed toward the surface with energies in the thermal range, meaning […]

Many methods can be used to synthesise non-molecular inorganic solids. Some solids can be prepared by a variety of routes but others, especially those that are not thermodynamically stable, may be much more difficult to prepare and may require special […]

The wave nature of light expresses itself in the propagation all over space, showing an intrinsic limitation to be localized beyond the so-called diffraction limit which is of the order of half the wavelength of the photons propagating. However when […]

Why people younger than 22 with congenital or acquired heart conditions should be more likely of developing a cancer? Actually, a small number of studies have been published, suggesting relatively high cancer incidence and mortality, compared to the general population. […]

Since the discovery that graphene, the two dimensional carbon allotrope, can be isolated and incorporated into electronic devices intense research efforts have been triggered. Driving forces usually mentioned behind the experimental and theoretical studies of graphene are the exceptional electronic […]

The electronic wave function of an n-electron molecule depends on 3n spatial and n spin coordinates. In a sense, the wave function of a many-electron molecule contains more information than is needed and is lacking in direct physical significance. This […]

Lipinski’s “rule of five”,1 very well known by medicinal chemists, has been defined as a set of rules, based on the number 5 -hence its name-, to evaluate the “drug-likeness” of a given molecule. The rules are:
– The […]

The most effective interventions in people with autism are based on a personal work by specialized professionals and these therapies, when well designed and well done, achieve a constant improvement in different areas such as social communication, the presence of […]

Topological insulators are materials with special universal properties, which are protected against perturbations. Such properties are theoretically described by topology, a branch of mathematics concerned with the properties of geometrical objects that are unchanged by continuous deformations. Concretely, topological insulators […]

After years of watching manufacturing plants relocating offshore, hundreds of thousands of jobs gone and deindustrialization creeping up, policy makers and investors from high-income countries are finally willing to bring the manufacturing sector back. But they won’t get this done […]
