Boron nitride nanotubes
(BNNTs) are structurally and mechanically
similar to carbon nanotubes (CNTs). In contrast, BNNTs exhibit unique
properties for being electrically insulating and optically transparent
due to the polarized boron nitride bonds. All these properties have
prevented the use of BNNTs for energy harvesting and electronic devices
for more than 25 years. During the past few years, researchers have
started to demonstrate a series of novel applications of BNNTs based
on unique properties not found on CNTs. For example, these novel applications
include osmotic power harvesting using the charged inner surfaces
of BNNTs, room-temperature single-electron transistors using insulating
BNNTs as the tunneling channels, high-brightness fluorophores that
can be 1000-times brighter than regular dyes, and transistors based
on Tellurium atomic chains filled inside BNNTs. We have reviewed some
of these emerging applications and provided our perspective for future
work.
Molybdenum disulfide quantum dots (MoS2 QDs) are a unique class of zero-dimensional (0D) van der Waals nanostructures. MoS2 QDs have attracted significant attention due to their unique optical, electronic, chemical, and biological properties due to the presence of edge states of these van der Waals QDs for various chemical functionalization. Their novel properties have enabled applications in many fields, including advanced electronics, electrocatalysis, and biomedicine. In this review, the various synthesis techniques, the novel properties, and the wide applications of MoS2 quantum dots are discussed in detail.
Boron nitride quantum dots (BNQDs) have gained increasing attention for their versatile fluorescent, optoelectronic, chemical, and biochemical properties. During the past few years, significant progress has been demonstrated, started from theoretical modeling to actual application. Many interesting properties and applications have been reported, such as excitation-dependent emission (and, in some cases, non-excitation dependent), chemical functionalization, bioimaging, phototherapy, photocatalysis, chemical, and biological sensing. An overview of this early-stage research development of BNQDs is presented in this article. We have prepared un-bias assessments on various synthesis methods, property analysis, and applications of BNQDs here, and provided our perspective on the development of these emerging nanomaterials for years to come.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
