Chemical Science, 2022 Herein, we show that twisted molecular nanoribbons with as many as 322 atoms in the aromatic core are efficient gelators capable of self-assembling into ordered π-gels with morphologies and sol–gel transitions that vary with the length of the nanoribbon.

AIP Advances, 2018 Realizing high performance silicon based light sources has been an unremitting pursuit for researchers. In this letter, we propose a simple structure to enhance electroluminescence emission and reduce the threshold of injected current of silicon/CdS ...

Magnetic Behavior in TiS3 Nanoribbon [PDF]
Materials, 2019 The electronic structure, magnetic properties and strain response of N-a-TiS3 nanoribbons are investigated by first-principles calculations. We find that the magnetic ground state is strongly dependent on width of a-TiS3. When N equals an odd number the ground state is a ferromagnetic (FM) metal, meanwhile, when N equals an even number the ground state

Metallic Graphene Nanoribbons [PDF]
Nano-Micro Letters, 2021 AbstractIsolated graphene nanoribbons (GNRs) usually have energy gaps, which scale with their widths, owing to the lateral quantum confinement effect of GNRs. The absence of metallic GNRs limits their applications in device interconnects or being one-dimensional physics platform to research amazing properties based on metallicity.

Anthracene‐Porphyrin Nanoribbons
Angewandte Chemie International Edition, 2023 Abstract π‐Conjugated nanoribbons attract interest because of their unusual electronic structures and charge‐transport behavior. Here, we report the synthesis of a series of fully edge‐fused porphyrin‐anthracene oligomeric ribbons (dimer and trimer), together with a computational study of the corresponding ...

Modeling nanoribbon peeling [PDF]
Nanoscale, 2019 Lifting and peeling of 2D materials and nanoribbons off surfaces is common in nanoscience. Solution of an analytical model shows that structural lubricity makes the peeling of a nanoribbon or film radically different from the standard description of peeling of immobile, fully glued films.

Ultranarrow TaS2 Nanoribbons [PDF]
Nano Letters, 2021 Imposing additional confinement in two-dimensional (2D) materials can yield further control over the associated electronic, optical, and topological properties. However, synthesis of ultra-narrow nanoribbons (NRs) remains a challenge, particularly for the transition metal dichalcogenides (TMDs), and synthesizing TMD NRs narrower than 50 nm has remained

Production of Tellurene Nanoribbons. [PDF]
Small MethodsABSTRACT The controllable synthesis of one‐dimensional (1D) nanostructures is foundational to nanotechnology but often relies on metal catalysts, introducing impurities and process incompatibility. Here, we demonstrate a catalyst‐free and broadly applicable strategy for the direct production of tellurene nanoribbons (TeNRs) via ...

Production of phosphorene nanoribbons [PDF]
Nature, 2019 Phosphorene is a mono-elemental, two-dimensional (2D) substance with outstanding, highly directional properties and a bandgap that depends on the number of layers of the material1-8. Nanoribbons, meanwhile, combine the flexibility and unidirectional properties of one-dimensional nanomaterials, the high surface area of 2D nanomaterials and the electron ...
