based nanodevices [91]. In gas sensing, the unique properties of 2D materials make them ideal for chemical detection, offering higher sensitivity and lower detection limits (LODs). Moreover, by combining two or
BP is a layered material that consists of single or multiple layers of phosphorus atoms arranged in a honeycomb structure. It has a puckered structure resulting from the strong covalent bonds within each layer and weak vdW interactions between layers [98,99,100]. The intricate structure endows BP...
Clearly, more work, some of which is ongoing and beyond the scope of this paper, is needed to answer some of these fundamental questions. To summarize, by selectively extracting both the Sc and Al atoms from a chemically in-plane ordered quaternary MAX phase (Mo2/3Sc1/3)2AlC, we ...
Answer true or false: In a covalent bond, the two nonmetal atoms share electrons. True or false? There is a double bond and a single bond around the central atom in ClO2-. A molecule has two or more atoms chemically bonded together. Is the statement true ...

In addition, 2D materials doped with than two or more kinds of heteroatoms are also attracted much attention [56,57]. Fig. 2h shows another important defects in 2D materials, the edge sites [2]. The unsaturated atoms at edges will produce remarkable differences in electronic features and ...
Furthermore, the sluggish movement of charge ions in PANI also results in a substantial decrease in electrochemical performance or gas sensitive performance [11]. Consequently, PANI is often combined with other materials to generate compound that improves its performance [12, 13]. MoS2, as a ...
This invention relates generally to chemical concentrate systems which may dispense compatible or incompatible actives in one or more systems. More specifically, the invention relates to a chemical concentrate system of at least two cooperative shapes which may provide at least one substantially continuous...
