Selective and low temperature transition metal intercalation in layered tellurides

Nature Communications, 2016
The intercalation of metal ions in layered structures has a wide variety of applications, from energy storage to environmental remediation. Here the authors report that layered telluride structures can selectively bind transition metals and this ...

Hydrocarbon influence on denitrification in bioturbated Mediterranean coastal sediments [PDF]

, 1997
An in situ experiment has been carried out inbioturbated Mediterranean coastal marine sediments (Gulfof Fos) in order to study the influence of hydrocarbons ondenitrification after 1, 4 and 6 months. In theabsence of hydrocarbons in the control sediments,

Synthesis of an organic-soluble π-conjugated [3]rotaxane via rotation of glucopyranose units in permethylated β-cyclodextrin

Beilstein Journal of Organic Chemistry, 2014
We synthesized symmetrically insulated oligo(para-phenylene) and oligothiophene with a pseudo-linked [3]rotaxane structure by full rotation of glucopyranose units via a flipping (tumbling) mechanism in the π-conjugated guest having two permethylated β ...
