Hydrocarbon Contamination in Angstrom-scale Channels [PDF]
Nanoscale, 2021,13, 9553-9560, 2021 Nonspecific molecular adsorption like airborne contamination occurs on most surfaces including those of 2D materials and alters their properties. While the surface contamination is studied using a plethora of techniques, the effect of contamination on a confined system such as nanochannels, nanopores leading to their clogging is still lacking.

Hexane-1,6-diammonium dinitrate [PDF]
Acta Crystallographica Section E Structure Reports Online, 2009 The hexane-1,6-diammonium cation of the title compound, C(6)H(18)N(2) (2+)·2NO(3) (-), lies across a crystallographic inversion centre and shows significant deviation from planarity in the hydro-carbon chain. This is evident from the torsion angle of -64.0°(2) along the N-C-C-C bond and thse torsion angle of -67.1°(2) along the C-C-C-C bonds.

Photooxidation of n-Hexanal in Air [PDF]
Molecules, 2001 Dilute mixtures of hexanal in synthetic air (up to 100 ppm) were photolyzed with fluorescent UV lamps (275-380 nm) in air at 298 K. The main photooxidation products, identified and quantitatively analyzed by FTIR spectroscopy, were butene, CO, vinylalcohol and ethanal.
