The study was designed to investigate the synergic effect of Ti and Sn in active metal brazing Al2O3 ceramic copper brazed, using multicomponent Ag-Cu-Zr filler alloy. Numerous fine hexagonal-shaped rod-like ternary intermetallic (Zr, Ti)5Sn3 phase (L/D = 5.1 ± 0.8, measured microns) were found dispersed Ag-Cu matrix Ag-18Cu-6Sn-3Zr-1Ti alloy, along with CuZrSn phases. An approximate 15° reduct...

The necessity to increase exposure in rare event search experiments by maintaining a low energy threshold and good resolution leads segmented detectors as EDELWEISS (Dark Matter), CUORE (0 $$\nu \beta \beta$$ ) or Ricochet (CENNS) for example. However, the large number of sub-elements can dramatically complexity such detector arrays. In this work we report on our progress towards designing flex...

In this study, semiconductor oxide cuprite (Cu2O) and indium tin (ITO) heterojunction solar cells with without a 10 nm thick titanium (Ti) thin film as the buffer layer were fabricated characterized for comparison. The Cu2O was formed by low-cost electrodeposition, Ti ITO layers deposited on glass substrate sputtering. interfacial microstructures, surface topology, electrical photovoltaic prope...

The use of dental implants is sometimes accompanied by failure due to periimplantitis disease and subsequently poor esthetics when soft-hard tissue margin recedes. As a consequence, further research is needed for developing new bioactive surfaces able to enhance the osseous growth. Tantalum (Ta) is a promising material for dental implants since, comparing with titanium (Ti), it is bioactive and...
