Sieving at the nanoscale: desalination of seawater through nanoporous graphene

MaterialsPhysics

By Silvia Román

Perhaps the most repeated words in the last few years when talking about graphene – since scientists Geim and Novoselov were awarded the Nobel Prize in Physics in 2010 for their groundbreaking experiments – are “the material of the future”. There are some risks regarding so many expectations about everything related to materials science, since […]

What is a radiation dosimeter? Why do we need one? To give you an interesting and short response I will remind you what the Japanese government officials offered to Fukushima evacuees after the 2011 nuclear disaster. Having failed to reach their original radiation decontamination target, the government proposed that evacuees could return to their homes […]

Of all the advances made in theoretical physics in the last twenty years, I still have no doubt that the most impressive one is the so called Maldacena’s conjecture, the guess that the physics involved in some models of quantum gravity living in a very concrete 5-dimensional spacetime has a one-to-one correspondence with the physics […]

Bicycles are usually regarded as the most sustainable mean of transport for urban environments. Now, when talking about sustainability, there are usually two different discussions: on the one hand, there is energy sustainability, as the fossil fuels won’t last forever and their secondary products are quite unhealthy. Bikes, being powered by people, fully comply with […]

Last month, a lot of newspapers and websites have been promoting this article on Nature referring to a recent preprint uploaded by Stephen W. Hawking to the internet repository ArXiv. In this work, summarizing what he talked about in a conference given last August, the English physicist argue that, since event horizons, the definitory property […]
