Two artefacts made of rock crystal (quartz) from the collection of the Musée du quai Branly in Paris, France, a skull approximately half of the size of a real cranium and a smaller anthropomorphic head, purportedly attributed to pre-Columbian Mesoamerican cultures, were studied to assess their authenticity. The surface of the artefacts were examined by means of optical microscopy and scanning e...

Changes in hydrogen distribution in -phase titanium hydrides (TiH1:92 1:95), covered with titanium oxide layers (TiO and TiO2), were investigated by elastic recoil detection analysis (ERDA) after isochronal and isothermal annealing experiments. The hydrogen concentration near to the surface of the hydride exponentially decreased as a function of annealing time in the temperature range from 423 ...

Since 1964, as an adjunct to its automated technical information processing services to ERDA and other federal agencies, a generalized language translation system has been used by the Oak Ridge National Laboratory (ORNL) to translate Russian scientific text to English. The translation system, first implemented at Georgetown University around 1960, has been rewritten and improved through the yea...

To investigate possible anomalies in nuclear reactions in solids, deuterium ion irradiation of deuterated Au/Pd samples have been performed with extensive measurements of reaction products and in situ characterization of the samples including ERDA and RBS. The D(d,p)t reaction rate has been observed to become three orders of magnitude greater than the calculated one. The deuterium density distr...

The composition, nanostructure, tribological and corrosion behaviour of reactive arc evaporated CrBxNy coatings have been studied and compared to CrN. The CrBxNy coatings were deposited on a commercial Oerlikon Balzers RCS coating system employing 80:20 Cr:B targets. To vary the composition, the nitrogen fraction was adjusted (N2 fraction = N2/(Ar + N2)) and a moderate bias voltage of –20 V was...

Abstract It is well known that some garnet compositions can incorporate hydrogen and/or fluorine at levels up to several wt%. However, accurate measurement of these elements be difficult trace minor concentration levels, so they are frequently ignored in routine chemical analysis. Furthermore, the mechanisms H incorporation still under debate, and only one mechanism for F substitution commonly ...
