| Nanoscience breakthrough: Probing particles smaller than a billionth of a meter
|
 Scientists at Tokyo Tech developed a new methodology that allows researchers to assess the chemical composition and structure of metallic particles with a diameter of only 0.5 to 2 nm. This breakthrough in analytical techniques will enable the development and application of minuscule materials in the fields of electronics, biomedicine, chemistry, and more.

| Supramolecular Nanowires from an Acceptor–Donor–Acceptor Conjugated Chromophore
|
| Taking charge: H‐bonding regulates H‐aggregation of an acceptor–donor–acceptor‐type oligothiophene derivative in which quaterthiophene is symmetrically conjugated with naphthalene monoimide (NMI) chromophores that are further connected to trialkoxy benzamide wedges to produce fibrillar nanostructures exhibiting remarkably high electrical conductivity. Abstract Oligothiophene derivatives have been extensively studied as p‐type semiconducting materials in organic electronics applications. This work reports the synthesis, self‐assembly and photophysical properties of acceptor–donor–acceptor (A–D–A)‐type oligothiophene derivatives by end‐group engineering of quaterthiophene (QT) with naphthalene monoimide (NMI) chromophores that are further connected to a trialkoxy benzamide wedge. Conjugation to the NMI units reduces the HOMO–LUMO gap significantly, and consequently the absorption spectrum exhibits a bathochromic shift of about 50 nm compared with QT. Furthermore, extended H‐bonding interactions among the ...

| How to induce magnetism in graphene
|
| Graphene, a two-dimensional structure made of carbon, is a material with excellent mechani-cal, electronic and optical properties. However, it did not seem suitable for magnetic applica-tions. Together with international partners, Empa researchers have now succeeded in synthesiz-ing a unique nanographene predicted in the 1970s, which conclusively demonstrates that car-bon in very specific forms has magnetic properties that could permit future spintronic applica-tions. The results have just been published in the renowned journal Nature Nanotechnology.

| Converting graphene into diamond film
|
 Can two layers of the "king of the wonder materials," i.e. graphene, be linked and converted to the thinnest diamond-like material, the "king of the crystals"? Researchers of the Center for Multidimensional Carbon Materials (CMCM) within the Institute for Basic Science (IBS, South Korea) have reported in Nature Nanotechnology the first experimental observation of a chemically induced conversion
