What is created when chemical reactions join atoms together? What is formed when atoms form covalent bonds? What is formed when elements of matter are chemically combined? What is formed when particles of two or more substances are distributed evenly among each other?
The optical properties of transition metal dichalcogenide monolayers are widely dominated by excitons, Coulomb-bound electron–hole pairs. These quasi-particles exhibit giant oscillator strength and give rise to narrow-band, well-pronounced optical trans
During the transformation, the planar 2D morphology can be normally retained, but the coordination of M atoms in reference to the surrounding X atoms becomes octahedral [61]. Such a transformation activates the catalytic property of the basal plane in the 2D planar structure, introducing more ...
Moreover, we have analyzed the EPC-favorable vibration modes in 2D MX (Fig. 2e–g and Supplementary Fig. 2e, f). Interestingly for monolayer ZrCl, the soft mode-1 at K point is mainly from Zr atoms that vibrate circularly but of opposite chirality between top and bottom sub-monolayers ...

Moreover, OR14I1 is proposed to be the receptor for human cytomegalovirus (HCMV) infection (Xiaofei et al., 2019). Therefore, ORs might be the potential targets for the pharmaceutical industry. Following clinical trials, a ligand for OR2AT4, Sandalore®, is now regarded as a therapeutic...
This process involves passing one or more precursor gases (which usually contain the atomic ingredients of the required film) through a heated furnace, where they will react together or with a substrate and form a thin layer of the required material. This process has been successfully applied to...

Correspondingly, intrinsic stacking faults in 3D boron form parallel layers of faulted planes in the same orientation as the exfoliated nanosheets, reducing the {001} cleavage energy. Planar defects represent a potential engineerable pathway for exfoliating 2D sheets from 3D boron and, more broadly, ...
[89]. The structure of TMDs is layered with the transition metal sandwiched between two chalcogens, which are bound together by weak vdW forces that make it easy to be exfoliate into single or few layers. TMDs have a variety of electronic band structures, covering materials such as conductors...
