When nanoparticles (NPs) get in contact with biological fluids such as blood, proteins present in it will adsorb on the surface of those NPs forming what is known as the protein corona . It is a dynamic process in equilibrium with the surrounding proteins and it may lead to drastic changes in the NPs. The […]
Floating structures are becoming increasingly popular. They are used by several industries, some have been in business for decades, like those dedicated to oil and gas, some are newer, like renewables (wind, wave, tidal), and there are still some other uses, like ports, while there is a constant flow of new ideas that imply their […]

Few materials have drawn as much attention as graphene, it fascinating attributes such as one-atom thickness and relativistic electrons, and its technological properties like transparency, large mechanical strength, and ultra-high electron’s mobility, position it as one of the more promising materials in the present. Recently, simultaneous experimental and theoretical studies have confirmed that combining graphene […]
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 solid in which atoms are positioned at random and have no long-range ordered pattern. These […]
Plants and animals are provided with startling self-healing and defence mechanisms. Think of how trees achieve wound closure after losing a limb through callus formation, or the ability of the chameleon to adapt the colour of the skin according to its surroundings through reversible muscle control. These are very well-known examples where living nature teaches […]

Mobile phones and computers are currently responsible for up to 8% of the electricity use in the world. This figure has been doubling each past decade but nothing prevents it from skyrocketing in the future. Unless we find a way for boosting energy efficiency in information and communications technology, that is. An international team of […]
The ability to examine the vibrational spectra of liquids with nanometer spatial resolution will greatly expand the potential to study liquids and liquid interfaces. After all, modern technology, including many manufacturing processes, and science depend on understanding the detailed interactions at such nanoscopic interfaces. Actually, a better comprehension of the fundamental properties of the commonest […]

Spacecraft components potentially exposed to different ionic projectiles in space, new materials used in new energy systems or healthy tissues exposed to cancer therapies are all instances where a full comprehension of how the energy of the incoming ions is dissipated by the matter in the target is of paramount importance. Besides, the dissipative processes […]
“What would happen if we could arrange the atoms one by one the way we want them?” Richard Feynman Fabrication of matter atom by atom remains a long-standing dream and ultimate goal of nanotechnology, following the famous challenge by Feynman 58 years ago. For 30 years, the atom-by-atom fabrication remained the province of visionary thinking […]
