Molecules Vs Compounds Although there is still some debate over the formal distinction, a molecule is a group of two or more atoms joined by chemical bonds, whereas a compound is a substance formed by the chemical bonding of more than one type of element that exists in a fixed proportion. ...

Moreover, the Si@TiO2@rGO electrodes still retained integrated sandwich-like structure and uniform element distribution after 100 cycles, which further revealed their stable physical and excellent electrochemical properties.

the search page can be used for locating compounds according to their structure type (single structure, mixture, alternate, formulation, alternate, polymer, and no structure). currently, numbers corresponding to the structure type (not the structure type itself) can be set as search criteria. plea...
As seen from the structure diagram, some GO sheet layers are exfoliated by the linear saturate and resin molecules, enters the asphalt. Consequently, the downward trend of the S1 and R curves at 11.024–11.457 nm and 11.889–12.321 nm is relatively gentle. The unflaked GO is still in an ...
Element transporters play crucial roles in the uptake and dispersal of mineral and heavy metal elements in plants. Exogenous biochar treatment had a significant effect on DEGs involved in the transportation of elements in a complex heavy metal environment. In the ABC family involved in heavy metal ...
As for hydrides, borides, and carbides, different types of nitrides are possible depending on the type of metallic element. The classifications of nitrides are similarly referred to as ionic (saltlike), covalent, and interstitial. However, it should be noted that there is a transition of bond...
After Compound E (5 g, 11.1 mmol) and Compound B (4.3 g, 11.1 mmol) were completely dissolved in tetrahydrofuran (THF, 100 mL), a 2 M aqueous potassium carbonate solution (50 mL) and then Pd(PPh3)4(0.38 g, 3 mol %) were added thereto, and the mixture was stirred under reflux fo...
However, in such a light-emitting element utilizing an exciplex, use of certain substances often prevents efficient light emission. Actually, in the history of development of organic EL elements, an exciplex has been considered to decrease efficiency and organic EL elements have been generally designe...
After that, a mixture of 50 mL of ethyl acetate and 50 mL of saturated sodium bicarbonate water was added thereto, and liquid separation was carried out. After the organic layer thus obtained was washed with saturated saline, it was dried with magnesium sulfate. The magnesium sulfate was ...
