Neutron diffraction studies of graphite-potassium-methylamine: staging transitions and structure of new graphite intercalation compounds

Article Abstract:

Graphite intercalation compounds (GICs) are an important class of materials that have many practical applications and allow us to study a variety of low-dimensional phenomena. Isotopic substitution of CD3ND2 for CD3NH2 has enabled to determine the detailed structure of the fully aminated stage-I and stage-II end compounds, C(sub 24)K[CH(sub 3)NH(sub 2)](sub 3) and [C(sub 48)K(CH(sub 3-NH(sub 2)](sub 3).

Unidirectional orientation of methylene blue intercalated in K (sub 4) Nb (sub6) O (sub 17) single crystal

Article Abstract:

Intercalation of methylene blue into K (sub 4) Nb (sub 6) O (sub 17) single crystals was investigated for the construction of hybrid materials with three-dimensional anisotropy. By the reaction of K (sub 4) Nb (sub 6) O (sub 17) with a methylene blue aqueous solution in the presence of propylamine, methylene blue/K (sub 4) Nb (sub 6) O (sub 17) interaction compounds were obtained.

Hydrogen adsorption in potassium-intercalated graphite of second stage: an ab initio molecular dynamics study

Article Abstract:

An ab initio molecular dynamics study on hydrogen adsorption in potassium-intercalated graphite of second stage is presented. The simulation utilizing the ultrasoft pseudopotenals wave method under local density functional approximation is described.
