“…This outcome can be understood in terms of the formation of the boundary layer at the interface between the flow and substrate. [ 28 ] Precisely, the boundary layer is the thin layer in the immediate vicinity of a bounding surface formed by the fluid flowing along the surface. In our case, we consider the boundary layer consisting of the Te vapor in (super)saturated condition floating on top of the Mo film substrate.…”

MoTe2 garnered much attention among 2D materials due to stable polymorphs with distinctive structural and electronic properties. Among the polymorphs, 1T’-MoTe2 in bulk form is type – II Weyl semimetal while, in monolayer form is a quantum spin Hall insulator. Thus, it is suitable for a wide variety of applications. Nevertheless, 1T’-MoTe2 degrades within a few hours when exposed to the atmosphere and causes hindrances in device fabrication. Here the degradation kinetics of CVD-synthesized 1T’-MoTe2 was investigated using Raman spectroscopy, XPS, and microscopic characterizations. The degradation rate of as-grown 1T’-MoTe2 obtained was 9.2 x 10-3 min-1. Further, we prevented the degradation of 1T’-MoTe2 by introducing a thin coating of S that encapsulates the flakes. 1T’-MoTe2 flakes showed stability for several days when covered using Sulphur, indicating 25 times enhanced structural stability.

Nanourchins are multibranched nanoparticles with unique optical properties and surface spikes. Because of their unique properties, gold nanourchins have advantages over gold nanoparticles. The most used nanourchins are gold, tungsten, carbon, vanadium and sea urchins. The synthesis of various nanourchins and their clinical advancement are discussed in this review. ZFNs, TALENs and CRISPR/Cas9 are discussed to facilitate understanding of advancements in nanourchins. Nanourchins have been studied for Parkinson's disease, Alzheimer's disease and bioimaging. The synthesis of molybdenum diselenide nanourchins and their bioconjugations are also discussed. Nanourchins can be further explored to improve drug targeting and delivery. Researchers from several fields may contribute to the study of nanourchins as prospective nanocarriers with target specificity.
