Solid state nuclear magnetic resonance spectroscopy (ss-NMR) is a very powerful technique for the investigation of all kind of solid materials, including pharmaceuticals, soils, organics, polymers, cements, ceramics or batteries among others. NMR spectroscopy provides evidence at an atomic level on the local environment of the nuclei difficult to obtain by other techniques.
Ss-NMR has been...
Hydrogen storage technologies play an important and crucial role in the so-called “hydrogen economy”. However, clay minerals have poorly been studied for this purpose, while they possess valuable properties (stability, low cost, green material) to be exploited in this domain.
We have recently studied H2 adsorption on synthetic smectite, specifically laponite and its gel (before hydrothermal...
We report a joint experimental and computational characterization of the adsorption process of toxic gases, such as CO, CO2 and SO2[1] in Hofmann-type clathrates with formula {Fe(pz)[MII(CN)4]} (M = metal, pz = pyrazine). These metal-organic frameworks have a 2D layered structure where Fe centers are connected through cyanide ligands to an open-metal site MII, typically Pd, Pt or Ni, offering...
Gas hydrates are crystalline structures consisting of cages resulting from the hydrogen bonding of water molecules (host) enclosing relatively small gas molecules (guest), such as hydrogen, methane and other small hydrocarbons [1]. Gas hydrates occur naturally on continental margins and in the permafrost region where the pressure and temperature conditions are favorable for hydrate formation...
