TL;DR: Mass production of one-dimensional, V2Se9 crystals, was successfully synthesized using the solid-state reaction of vanadium and selenium and through the mechanical exfoliation method, the bulk V2 Se9 crystal was easily separated to nanoribbon structure and it was confirmed that as-grown V2Sem9 crystals consist of innumerable single V2se9 chains linked by van der Waals interaction.

TL;DR: In this paper, a novel semiconductor 1D nanomaterial, Nb2Se9, was synthesized on a bulk scale via simple vapor transport reaction between niobium and selenium.

TL;DR: In this article, a room-temperature (∼26 °C) NO2 gas sensor was fabricated using tellurium (Te) nanostructures, which formed a helical chain with strong covalent bonds in the c-axis and weak van der Waals bonds between the chains.

TL;DR: The results will not only help to add a novel quasi-1D block for nanoelectronics devices based on 2D van der Waals heterostructures, but also provide crucial information for designing proper contacts in device architecture.

TL;DR: These dangling-bond-free 2D Nb2Se9 sheets are expected to be applied in optoelectronic devices because they allow for nearly direct band gaps and can be used in mechanical sensors because the band gaps can be controlled by varying the interchain strain.
