Each type of carbonated water has a unique chemical structure, which affects its flavor. For example, mineral water consists of carbon dioxide and water. This mixture is forced through a small opening at high pressure, creating the sparkling effect. Crisp carbonated water is composed of carbon di...

Here, we report the first experimental measurements of the ultimate tensile strengths of individual structure-defined, single-walled carbon nanotubes. The strength depends on the chiral structure of the nanotube, with small-diameter, near-armchair nanotubes exhibiting the highest tensile strengths. This...

It is the nature of these oxidations to preserve (CH) and larger bridges always as the predominant product from such systems and usually in yields of over 50%. In contrast simple CH are almost completely destroyed to form carbon dioxide and water. 18 references, 2 tables. 展开 ...
Carbon dots (CDs) are one of the advancing fluorescent materials, which draw increasing attention in both theoretical research and practical applications. However, the clear chemical structure and photoluminescence (PL) mechanism of CDs is still an open debate, which limits the development of CDs. ...
Chemical insertion of carbon dioxide into epoxides under ambient conditions has become one of the most important methods for the construction of cyclic organic carbonates. Various active salen, salophen, and phenolate ligand based complexes have been reported for the synthesis of cyclic organic carbonate...
Chemical bonding - Atomic Structure, Intermolecular Forces, Covalent Bonds: To understand bond formation, it is necessary to know the general features of the electronic structure of atoms—that is, the arrangement of electrons around the central nucleus.
