Tiny selenium particles could have a therapeutic effect on ischemic brain strokes by promoting the recovery of brain damage. Pharmacologists, including Alireza Mashaghi from the Leiden Academic Centre for Drug Research discovered that selenium nanoparticles inhibit molecular mechanisms that are responsible for the loss of brain cells after a stroke. The results were published in…
Graphene Layers Caught “Kissing”
University of Leiden physicists and chemists have managed to bring two graphene layers so close together that an electric current spontaneously jumps across. In the future, this could enable scientists to study the edges of graphene and use them for sequencing DNA with a precision beyond existing technologies. The study has been published in Nano…
Graphene Floating on Water Attracts Water
Graphene floating on water does not repel water, as many researchers believe, but rather attracts it. This has been demonstrated by chemists Liubov Belyaeva and Pauline van Deursen and their supervisor Grégory F. Schneider, and published in Advanced Materials. Graphene is made up of the same material as graphite — found in pencils, for example…
