Why tert-butyl alcohol associates in aqueous solution but trimethylamine-N-oxide does not

Article Abstract:

Molecular dynamics simulations are used to study the models representing tert-butyl alcohol (TBA) and trimethylamine-N-oxide (TMAO) that differ essentially only in their electrostatic properties. It is shown that this difference is sufficient to give different solution behavior. Hydrogen-bond analysis shows that water-TBA and water-TMAO hydrogen bonds are similar in number, but that the hydrogen-bond energy is much negative for water-TMAO.

Hydrogen sorption on palladium-doped sepiolite-derived carbon nanofibers

Article Abstract:

The hydrogen sorption behavior of novel Pd-doped sepiolite-derived carbon nanofibers (SDCNs) is investigated. The hydrogen sorption behavior examined by differential scanning calorimeter has displayed that a higher amount of hydrogen desorbed at around 860 K from the Pd-doped SDCNs compared to that from the undoped SDCN.
