Enhancing covalent organic framework diversity through isomerism
Mar 06, 2024 (Nanowerk News) Researchers at Tokyo Institute of Technology for the first time discovered the selective generation of three types of structural isomers (a set of different nanostructures with an identical chemical composition) of three-dimensional covalent organic frameworks (3D-COFs), emerging nanoporous solids proposed for many applications, creating new...
Turning skin cells into limb cells sets the stage for regenerative therapy
Mar 05, 2024 (Nanowerk News) In a collaborative study, researchers from Kyushu University and Harvard Medical School have identified proteins that can turn or “reprogram” fibroblasts — the most commonly found cells in skin and connective tissue — into cells with similar properties to limb progenitor cells. Publishing in Developmental...
Ballistic transport in long molecular wires: porphyrin nanoribbons
Mar 05, 2024 (Nanowerk News) The conductance of classical electric components (i.e. how much current a wire sustains at a given applied voltage) typically decays with increasing length. In general, this is also the same behaviour found at the nanoscale with 1D molecular wires. Now, researchers have demonstrated that, once...
