The current noise in bolometers with a negative temperature co efficient has been ascribed to poor electrical contacts /1, 2/. It is found also that a major portion of the noise can be attributed to the method of applying ...

Apatite- mullite glass-ceramics have been developed recently as dental materials. The

effect of L1OZ and B2O3 content on the sintering and devitrification behaviour ol glasses in

the AI2O3-SiO2-P2O5-CaF2-CaO ...

The aim of this study was to investigate and compare the fatigue strength of maxillary premolars restored with two CAD/CAM ceramics, lithium disilicate e.max® CAD (LD) and polymer-infiltrated ceramic Enamic® (PIC).Materials and methods Twenty...

Among advanced ceramics, a significant candidate for high tech functional and structural applications, Zirconia, has been a special interest. An intense interest in zirconia-based ceramics results from a number of key characteristics. They include...
