Deuterium loading of palladium cathodes in Pons-Fleischmann type electrolytic cells has been observed to result in generation of excess heat on several occasions. Metallurgical examination of some of the electrodes showed extensive damage associated with deuterium loading. Surfaces have been found to be covered with large number of impurities. Initiation and sustaining these heat bursts, monito...

The hot compaction of nanocrystalline TiO2 anatase powders is investigated using dilatometry. The constant rate of heating (CRH) method is applied to determine effective activation energies of the processes involved during sintering. Grain size and doping effects are studied, using dopant cations of different radius and charge: Zn, Al, Si, Nb. The results are interpreted by a mechanism includin...
