“…The parallel LAMMPS software package is employed for simulation [34]. The x, y, z axes of simulation box are along the [111], [-1-12], and [1][2][3][4][5][6][7][8][9][10] crystallographic orientations, respectively. In order to study the dependence of the deformation behaviour on the crystallographic orientation of NW, we rotate the atoms around the z-axis to 0°, 30°, 60°, 90°, 120°, respectively.…”

“…In recent years, nanoscale metal materials have attracted extensive interest due to superior mechanical, magnetic and thermal properties [1][2][3][4]. Nanowire (NW), as one of the most representative low-dimensional nanostructured materials, has widely used in various fields [5][6][7]. Therefore, understanding the deformation behaviour of metal NW becomes an essential task for the optimal design and wide application.…”

The effects of crystallographic direction and temperature on the deformation mechanism and properties of Cu nanowire (NW) are studied via systematic simulations and theoretical analysis. It is found that the elastic module, yield stress and yield strain are quite different for five oriented NWs. As the crystallographic orientation of NW varies, both the yield stress and the yield strain firstly reduce to the minimum value, then gradually increase. Furthermore, the evolutions of flow stress after yield point are also obviously different for five oriented NWs, which are associated with the plastic deformation mechanisms. With the crystallographic orientation of NW varying, the simulated atomic snapshots show that the dominant deformation mechanism transforms from the shuffling-assisted single dislocation-nucleation to the collective dislocation-nucleation, then to the twinning migration, and finally to the combination of dislocation glide and microtwinning. According to the normal stress perpendicular to the slip plane and shear stress on the slip plane, the authors theoretically predict the deformation mechanisms for different oriented NWs, which turn to be in good consistent with the authors' observed deformation mechanisms. Besides, they also propose that the temperature effects are different for different oriented NWs.

“…[102] Most often, nonarray nanowires are used as nanoscale needles to deliver materials intracellularly with precision ( Figure 7b). [103] Nanowires are readily taken up by cells: one study reported targeted delivery of a cytokine into a single cell using gold nanowires, through manipulation of the electric field. [104] The ability to deliver signaling molecules at the singlecell resolution is an impressive step toward understanding cellular behavior through signaling pathways as well as targeted drug delivery and therapies.…”

Nanostructured materials can now be engineered with great precision and complexity as a result of advances in design and fabrication, and offer distinct advantages in many biosensing and biomedical applications. The materials most widely used in this field are semiconductors and noble metals. Each offers multiple length scales of nanostructuring that program their physicochemical properties for different biosensing applications. Here, nanostructured materials and their applications are reviewed together with semiconductors and noble metals, as well as hybrid materials that unite these two classes—all with the goal of linking performance characteristics to applications in biomedicine.

“…Metallic quantum dots, in their nanocomposite form, have been proposed for use in memory devices [12,13] and in coloring glasses. By using the multicolor detection properties of semiconductors, optical devices applicable in nanoscience and nanotechnology, as well as in chemistry, biology, and medicine, can be developed [14][15][16][17][18][19][20][21][22][23][24]. As far as we know, metallic Zn quantum dots have not been studied or reported in the recent scientific literature.…”

The structural and electronic properties of the metallic hcp phase of Zn in the bulk, monolayer, bilayer, and quantum dot limits have been studied by using total energy calculations. From our calculated density of states and electronic band structure, in agreement with previous work, bulk hybridization of the Zn-4s, 3p, and 3d orbitals is obtained. Furthermore, we found that this orbital hybridization is also obtained for the monolayer, bilayer, and quantum dot systems. At the same time, we found that the Zn monolayer and bilayer systems show electronic properties characteristic of lamellar systems, while the quantum dot system shows the behavior predicted for a 0D system.
