(Phys.org)—Researchers from Technische Universität München in Germany have succeeded in covalently binding porphine to the edge of a graphene sheet on a Ag(111) substrate using surface-assisted covalent coupling. This ...
(Phys.org)—Researchers from the University of Lisbon and the North Lisbon Hospital Center (Centro Hospitalar Lisboa Norte) conducted a pilot study that demonstrated how atomic force microscopy (AFM) could be used as a non-invasive ...
(Phys.org)—As scientists look for alternative energy sources, fuel cells that operate in a basic environment have garnered much attention. Typically fuel cells require an expensive catalyst, such as platinum. Hydroxide ...
Nature packs away carbon in chalk, shells and rocks made by marine organisms that crystallize calcium carbonate. Now, research suggests that the soft, organic scaffolds in which such crystals form guide crystallization by ...
