Assembling Nanometer Nickel Particles into Ordered Arrays

Directed Deposition of Nickel Nanoparticles Using Self‐Assembled Organic Template

“…From the presented STM images, it is clear that the metal nanoparticles are in direct contact with the bands formed by fatty acids (Figure 11(a)). Particles connection with the surface may be attributed to the attractive van der Waals interactions between the hydrophobic hexadecylamine outer shell of nickel particles and the ordered octadecanoic acid layer on HOPG [20]. In the case of Figures 11(a) and 11(b), the template bands are twice wider than the single length of octadecanoic acid (2.1 nm).…”

“…The metal-line formation is partial, not completely filled with cluster assemblies, and the investigated structures so far are only stable in the liquid environment of the solution. Lei et al reported the synthesis and assembly of 1-dodecanethiol capped nickel particles using an alkaneassembling monolayer [20].…”

Ammonia‐Assisted Fabrication of Flowery Nanostructures of Metallic Nickel Assembled from Hexagonal Platelets

“…[10,11] For example, nickel nanoparticles modified with C12SH formed an ordered assembly through attractive van der Waals interactions between the hydrophobic outer face of the nickel subunits. [12] Nickel nanorods covered with hexadecylamine spontaneously organized into aggregates with their long axes parallel to each other. [13] However, in these assemblies, the content of or-their simultaneous assembly into flowery architectures.…”

“…[14] When immersed into some solvents, dissolution of the "mortar" made the assembly collapse, which resulted in difficulty in their applications as nanodevices. [12,13] Another efficient method to build nickel assembly nanostructures is by the direction of magnetic field, which typically produces 1D chains of particles with the magnetic dipoles aligned head-to-tail and parallel to the magnetic field. [15][16][17] For instance, colloidal nickel nanoparticles self-assembled into nanochains when subjected to a magnetic field with a strength of about 250 Gauss.…”

Two dimensional self-assembly of bis-acylureas having various functional end groups

“…Researchers have worked on various organic 2D nanomaterials, such as graphene derivatives [4], polymeric nanodiscs [5], and self-assembled monolayers on substrates [6]. The potential of such 2D organic nanomaterials in material science, however, are more clearly witnessed when combined with inorganic nanomaterials [7].…”
