  • Secret messages hidden in light-sensitive polymers

    DNA is a long chemical sequence that carries genetic information. Inspired by this biological system, in recent years many research teams have been exploring how to store and then decode information within synthetic macromolecules, also called polymers. In a leap forward in this field, researchers a more

  • Researchers have discovered how a nanocatalyst works at the atomic level

    The researchers of the Nanoscience Center (NSC) at the University of Jyväskylä, Finland, and in the Xiamen University, China, have discovered how copper particles at the nanometre scale operate in modifying a carbon-oxygen bond when ketone molecules turn into alcohol molecules. Modification of the c more

  • Decoupled graphene thanks to potassium bromide

    The use of potassium bromide in the production of graphene on a copper surface can lead to better results. When potassium bromide molecules arrange themselves between graphene and copper, it results in electronic decoupling. This alters the electrical properties of the graphene produced, bringing th more
