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

Microalgae cultivation for lipids and carbohydrates production [PDF]

open access: yes, 2017
Microalgae are photoautotrophic microorganisms that can produce energy both by using sunlight, water and CO2 (phototrophic metabolism) and by using organic sources such as glucose (heterotrophic metabolism).

Coordination chemistry of perhalogenated cyclopentadienes and alkynes. 8. Pentakis(dimethylsilyl)cymantrene [PDF]

open access: yes, 1992
Starting from [q5-C5Br5]M n(CO),, the first r-complex of a cyclopentadienyl ligand with five silyl substituents, [q 5-C5(SiMe2H)5M] n(CO),, was prepared by a series of halogen-lithium exchange reactions, followed by silylation with SiMe2HCI.

4,4′-(Hexane-1,6-diyldioxy)dianiline [PDF]

open access: yesActa Crystallographica Section E Structure Reports Online, 2009
The complete molecule of the title compound, C(18)H(24)N(2)O(2), is generated by a crystallographic inversion centre. The torsion angles in the hexa-methyl-ene chain are consistent with an anti-periplanar conformation, whereas the conformation of the O-CH(2)-CH(2)-CH(2) unit is gauche.

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 ...

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 ...

Light‐Controlled Reversible Coassembly of Hybrid Functional Nanostructures

open access: yesAdvanced Functional Materials, EarlyView.
Light‐responsive hybrid nanostructures are formed by coassembling azobenzene‐ and PAH‐functionalized nanoparticles through reversible an tunable π interactions. The system enables tunable coupling between distinct components such as gold and magnetite or carbon nanotubes, producing switchable optical and magnetic properties under light and magnetic ...

Heterogenisation of ketone catalysts within mesoporous supports for asymmetric epoxidation

open access: yes, 2013
The synthesis of the first mesoporous silica (150 Å) anchored carbohydrate-derived chiral ketone is described. This new heterogeneous catalyst has been shown to be effective in the asymmetric epoxidation of olefins by oxone.
