The adsorption selectivities between dithiothreitol (DTT) and 1,4-butanedithiol 2,3-diamino (BDD) were revealed through density functional theory (DFT) calculations. DFT calculations predict that DTT does not stably adsorb onto the Ge(100) surface because both hydroxyl and thiol group in DTT ...
Common examples of alkanes are methane, ethane, propane, butane, and octane. The C-H bond is highly covalent and alkanes are very non-polar. They do not mix with water. Alkyl carbons are sp3hybridized and have tetrahedral geometry about the carbon. You can often think of alkyl groups as ...
A series of α,ω-aldehyde-capped thiophene oligomers with two, four and six thiophene units have been prepared via a convenient, three-step synthesis in good yields. The UV-vis spectral data show that the π-conjugation length in the tetramer is longer than those in the hexamer and in the...
The molecule contains a ketone and an ester functional group. The polarity of the polar bonds is shown below. Learn more about this topic: Functional Groups Overview & List from Chapter 5/ Lesson 20 145K Learn about functional groups. Understand what functional groups are, and explore ...
Organic compound with a hydroxyl group bonded to a carbon atom. Example: 1-Butanol. Ether Organic compound with an oxygen atom bonded to two alkyl or aryl groups. Example: Diethyl ether. Thiol Organic compound with a sulfhydryl functional group. Example: 1-Butanethiol. Sulfide Organic compound ...
On the role of aminolysis and transesterification in the synthesis of -caprolactone and L-lactide based polyurethanes Polyurethanes based on a 50/50 copoly(L-lactide/-caprolactone) prepolymer and butanediisocyanate were made. Chain extending a diisocyanate terminated prepo......
Oxygen-containing carbons are promising supports and metal-free catalysts for many reactions. However, distinguishing the role of various oxygen functional groups and quantifying and tuning each functionality is still difficult. Here we investigate the r
