water/ dissociationwaterscanning tunnelling microscopeWe have bombarded amorphous water clusters adsorbed on Cu(1 1 1) with electrons from the tip of a low-temperature scanning tunnelling microscope. Dissociation of the water molecules is induced by reaching an anti-bonding orbital at U D=(1.6±0.5...
We find that two water molecules can be dissociated consecutively by overcoming moderate energy barriers of a few tenths of eV, accompanied by the generation of a H2molecule for all three clusters. Depending on the cluster size, the fullerene clusters may participate directly in water splitting or...
FIG. 1A shows a method employing ultra fast dissociation of water molecules in accordance with the present invention. FIG. 1B shows a simplified block diagram of a photodissociation system employing the ultra fast dissociation method illustrated in FIG. 1A in accordance with the present invention....
Each phase has a characteristic network structure of water molecules, depending on pressure and temperature conditions. At high pressures above 2 GPa, ice has high-density packing structures con- sisting of interpenetrating diamond-like sublattices, in which each oxygen atom is surrounded by eight...
The adsorption of water molecules on Si(111)-7 x 7 surface is investigated by scanning tunneling microscopy (STM) at elevated temperatures. With further scission of OH bond above 290℃, the complete decomposition of water molecule into two H atoms and one O atom can now be observed directly...
The results of field emission microscopy measurements of work function changes while heating the water covered W tip are presented. At temperatures up to 280K non-dissociated H 2 O particles are present on the tip. Warming the tip at 300K caused these molecules to dissociate to OH and H. OH...
Solvation shell structure of NaCl in water Fig. 1: Angular distribution functions at ambient and extreme conditions. Full size image To identify the orientation of water molecules we used the angle between Na–O and Cl–O bonds and the water dipole moment, denoted asθ(Na–O) andθ(Cl–O...
