Recent Advances in Ultrathin Two-Dimensional Nanomaterials

Abstract

Since the discovery of mechanically exfoliated graphene in 2004, research on ultrathin two-dimensional (2D) nanomaterials has grown exponentially in the fields of condensed matter physics, material science, chemistry, and nanotechnology. Highlighting their compelling physical, chemical, electronic, and optical properties, as well as their various potential applications, in this Review, we summarize the state-of-art progress on the ultrathin 2D nanomaterials with a particular emphasis on their recent advances. First, we introduce the unique advances on ultrathin 2D nanomaterials, followed by the description of their composition and crystal structures. The assortments of their synthetic methods are then summarized, including insights on their advantages and limitations, alongside some recommendations on suitable characterization techniques. We also discuss in detail the utilization of these ultrathin 2D nanomaterials for wide ranges of potential applications among the electronics/optoelectronics, electrocatalysis, batteries, supercapacitors, solar cells, photocatalysis, and sensing platforms. Finally, the challenges and outlooks in this promising field are featured on the basis of its current development.

Tellurium: Fast Electrical and Atomic Transport along the Weak Interaction Direction

“…Our work reveals the unconventional properties underlying the superior performance of Te, while providing insight into the transport in anisotropic materials. Two-dimensional (2D) materials, such as graphene, MoS 2 , black phosphorus and hexagonal boron nitride, show great promise for many applications, including electronics, optoelectronics, energy conversion, and energy storage 1 . Recently, few-layer Te joins the family of 2D materials [2][3][4][5][6][7] .…”

Production of monolayer-rich gold-decorated 2H–WS2 nanosheets by defect engineering

“…[1][2][3][4][5][6][7][8][9][10] Numerous production techniques to obtain 2D-materials exist, with exfoliation in liquid particularly attractive due to its ease, scalable production of bulk quantities, and the possibility of further solution processing. 11 Several distinct exfoliation techniques in liquid are available, with the simplest being liquid-phase exfoliation (LPE).…”

Novel method to reduce Inter Core Communication in a Multi Core System

“…Copying data from the transmission data bank to the receiver data bank is carried out with the help of linked lists. Authors of [8] have described the concept of linked list and the various methods of memory transfer. The transmission data bank pushes the data into the list and the receiver data bank pops the data from the list.…”
