Metallic NbS One-Dimensional van der Waals Heterostructures.

This study presents the experimental demonstration of metallic NbS-based one-dimensional van der Waals heterostructures using a modified NaCl-assisted chemical vapor deposition strategy. By employing a ″remote salt″ strategy, we realized precise control of the NaCl supply, enabling the growth of high-quality coaxial NbS nanotubes on single-walled carbon nanotube-boron nitride nanotube (SWCNT-BNNT) templates. Using this remote salt strategy, the morphologies of as-synthesized NbS could be tuned from 1D nanotubes to suspended 2D flakes.

Janus MoSSe Nanotubes on 1D SWCNT-BNNT van der Waals Heterostructure.

Two-dimensional (2D) Janus transition metal dichalcogenide (TMDC) layers with broken mirror symmetry exhibit giant Rashba splitting and unique excitonic behavior. For their one-dimensional (1D) counterparts, the Janus nanotubes possess curvature, which introduces an additional degree of freedom to break the structural symmetry. This can potentially enhance these effects or even give rise to novel properties.

However, evidence regarding the relationship between PM and CVD risk factors remains inconsistent. We hypothesized that this association may be partially modified by socioeconomic status (SES).

Superatomic Layer of Cubic MoS Clusters Connected by Cl Cross-Linking.

Superatomic clusters - assemblies of atoms with various sizes, shapes, and compositions - can form hierarchical architectures that exhibit emergent electronic properties not found in their individual units. In particular, cubic MX clusters of chalcogenides (M = transition metal; X = chalcogen) are recognized as versatile building blocks for 3D structures with tunable morphologies and electronic properties. However, tetrahedral MX clusters rarely assemble into 2D architectures, which could offer a distinct class of functional materials from their 3D analogues.

Production of Double-Stranded RNA in Planta by a Potato Mop-Top Virus (PMTV)-Based Vector for Inducing Gene Silencing.

RNA silencing (also known as gene silencing) is an evolutionary conserved mechanism that is involved in regulating gene expression, suppressing mobile elements, and defensing virus infection. RNA silencing is triggered by double-stranded RNA via Dicer or Dicer-like riboendonucleases. DsRNAs are also the replication intermediates of all RNA viruses; as a result, plant RNA viruses are ideal candidates to induce RNA silencing.

Nanoscrolls of Janus Monolayer Transition Metal Dichalcogenides.

Tubular structures of transition metal dichalcogenides (TMDCs) have attracted attention in recent years due to their emergent physical properties, such as the giant bulk photovoltaic effect and chirality-dependent superconductivity. To understand and control these properties, it is highly desirable to develop a sophisticated method to fabricate TMDC tubular structures with smaller diameters and a more uniform crystalline orientation. For this purpose, the rolling up of TMDC monolayers into nanoscrolls is an attractive approach to fabricating such a tubular structure.

However, the low dielectric properties of monolayers prevent the generation of high concentrations of thermally excited carriers from doped impurities.
