Understanding the mechanism of NO2 interaction on semiconductor surfaces such as TiO2 is a key step in designing the catalytic processes for conversion of NO2 to useful products. In the present wor...

We study the stability and mechanical properties of adamantane-derived nanothreads (ANTs) and compare them with benzene-derived nanothreads (BNTs) using the density functional theory. The zigzag-catafused ANT has better thermodynamic stability, failu

Adsorption and functional transformation of 2,4,6-trinitrotoluene (TNT) are highly desirable to create a safer environment. Using first principles electronic structure calculations and MD simulations, we have examined the adsorption and catalytic con

Isoquinoline-based polycyclic lactams such as isoindoloisoquinolinones, pyrroloisoquinolinones, and benzo[a]quinolizinones were successfully assembled from the corresponding imides by using a TfOH-mediated (TfOH = trifluoromethanesulfonic acid) imide

Metal nitride nanosheets has attracted remarkable importance in surface catalysis due to its characteristic ionic nature. In this paper, using density functional theory, we investigate geometric stability and electronic properties of hydrogenated Ico

Quantum chemical analysis shows aza-graphane isomers, with alternate C-H and N: sites as ideal organocatalysts; their kinetic stability arises from the tertiary orthoamide. DFT calculations give split-off bands originating from nitrogen lone-pairs wi

Free standing silicene nanosheets remain elusive presumably due to the instability associated with sp(2) hybridized silicon atoms. Here we show that silicon prefers nanosheets based on the non-classical Si5 unit with a [1.1.1]-propellane motif that h

A systematic quantum chemical inquiry on supraicosahedral boranes (B n H n 2− , n > 12) reveals that larger polyhedral boranes no longer prefer pure deltahedral structures. In an attempt to avoid vertices that has six polyhedral neighbors ( hex-cap

Racemic erythrinarbine (IVb) and further tricyclic lactams (II) and (IV) are readily prepared via a TfOH-mediated cyclization reaction.
