Hexane-1,6-diammonium dinitrate [PDF]

open access: yesActa 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.

Liquid n-hexane condensed in silica nanochannels: A combined optical birefringence and vapor sorption isotherm study

open access: yes, 2009
The optical birefringence of liquid n-hexane condensed in an array of parallel silica channels of 7nm diameter and 400 micrometer length is studied as a function of filling of the channels via the vapor phase.

Effect of ion hydration on the first-order transition in the sequential wetting of hexane on brine

open access: yes, 2003
In recent experiments, a sequence of changes in the wetting state (`wetting transitions') has been observed upon increasing the temperature in systems consisting of pentane on pure water and of hexane on brine. This sequence of two transitions is brought

Synthesis and conformations of [2.n]metacyclophan-1-ene epoxides and their conversion to [n.1]metacyclophanes [PDF]

open access: yes, 2017
A series of syn- and anti-[2.n]metacyclophan-1-enes have been prepared in good yields by McMurry cyclizations of 1,n-bis(5-tert-butyl-3-formyl-2-methoxyphenyl)alkanes.

Hexane neem leaf extract more potent than ethanol extract against Aspergillus flavus [PDF]

open access: yesUniversa Medicina, 2014
Background Aspergillus flavus is one of the causes of aspergillosis, with a high virulence and resistance to standard antifungals, resulting in a high mortality rate. Medicinal plants are increasingly used as they are relatively safer with minimal side

Hexane-1,6-diammonium hexafluorosilicate [PDF]

open access: yesActa Crystallographica Section E Structure Reports Online, 2013
The asymmetric unit of the title organic–inorganic molecular salt, C6H18N2 2+·SiF6 2−, consists of one anion and one cation together with half of each of two cations and two anions located on inversion centres. The SiF6 2− octahedral anions are arranged to form sheets parallel to (011), which are ...

Charge-transfer photodissociation of adsorbed molecules via electron image states

open access: yes, 2007
The 248nm and 193nm photodissociation of submonolayer quantities of CH$_3$Br and CH$_3$I adsorbed on thin layers of n-hexane indicate that the dissociation is caused by dissociative electron attachment from sub-vacuum level photoelectrons created in the ...
