One thing is designing an object in a computer, and another, quite different, is producing it as a real 3D object. All other things being equal, in general the more curves the designed object has, the more difficult it is […]

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 […]

Reducing weight in all kinds of vehicles is currently one of the hot topics for Materials Science and Product Design. This goal is directly related to one of the grand challenges that society is facing, that is, mitigate greenhouse gases […]

Nowadays, the industry is centering their efforts on the development of single aerial robots carrying single objects, such as the widely-known drone of Amazon for delivering packages, which was followed by some national post-office services. However, other approaches go a […]

Trains are one of the least consuming means of transport, and it is mainly due to the metallic wheels and rails: there is almost no energy dissipation due to the rolling contact. Of course, not everything is so great with […]

In lay people’s minds, railway lines are composed by rails and wooden sleepers on a bed of stones. These medium-sized stones are called ballast, and it is true that they are the most common material to lay the track […]

Trains have a huge seasonal problem each autumn: leaves. Yes, leaves from the trees. And now they are testing a solution: laser beams! It sounds absurd, but it will all make sense after we get into its science.

Every autumn […]

Materials science is becoming more and more an interdisciplinary field in which almost every traditional subject has its say. Disciplines such as biology, medicine, computational design, architecture or even music, painting or sculpture converge on this open-minded host. As a […]

If you have a bike, most surely you will own a helmet too. If you fall off the bike your helmet might avoid some nasty head injuries, right? That looks pretty obvious… except that it isn’t.

Lets start with a […]
