MANY transitions in solids have in the past been regarded as being due to, or accompanied by, the onset of ionic or molecular rotation. There is, however, little convincing evidence that ions or molecules can rotate freely in crystal lattices. The balance of available data is against this ...

What is the formula for an ionic compound made of carbon and oxygen? What is carbon and its allotropes? What is the molecular mass of carbon? What is the chemical formula for hydrocarbon? What is the formula for alkenes? What is the empirical formula of benzene?
using mesoporous silica molecular sieves as the template [101]. Inside the mesopores of the silica molecular sieves, sucrose was converted to carbon through a mild carbonization process. The highlight of this research was that the obtained structure was not simply a negative replica of the used ...
The molecular Kondo effects of Co-tetra-pyridyl-porphyrin (Co-TPyP) molecules could be switched by different supramolecular environments. When Co-TPyP were trapped inside 2D nanoporous networks on Cu(111) or Au(111), the Kondo effect associated with the Co center could be switched on and off...
In the molecular structure of 5, the boron centre has B ¼ C double-bond character (B2–C7 ¼ 1.456(3) Å) and the second equivalent of tBuNC coordinates to the boron atom in the B ¼ C moiety. In the case of 6, the tBuNC moiety has consecutive N ¼ C and C ¼ C ...
(Fig.2f) increase steadily at higher CTAB concentrations, suggesting that CTAB indeed plays an important role in promoting activity and stereoselectivity of racemate. To eliminate the effect of bromide ion (Br−) in CTAB, NaBr was used for electrolysis, and the reaction rate slightly decreased ...
Rheological properties of tetra-n-butylphosphonium bromide hydrate slurry flow Clathrate hydrate slurries can be considered as two-phase refrigerants due to their high energy densities. The heat of formation of many clathrate hydrates... P Clain,A Delahaye,L Fournaison,... - 《Chemical Engineering...
Exfoliated graphene oxide was electrochemically reduced by the potentiostatic method (the color changed from yellow-brown to black) on SPE doped with ionic liquid, presenting a uniform surface topography. This nanomaterial promoted the oxidation of NADH on this modified electrode by increasing the electr...
To achieve this, polymeric binding agents (i.e., Nafion® and polytetrafluoroethylene) are employed [9]. (iv) Separators: The function of the separator is to electrically isolate the two electrodes, which would make it possible to prevent short circuits and guarantee ionic conductivity [12,...
