Journal of Prosthodontics, EarlyView.Abstract Purpose To investigate the effects of the elemental composition and the manufacturing process of cobalt chromium–molybdenum (CoCr–Mo), cobalt chromium–tungsten (CoCr–W), and CoCr–Mo‐W alloys on metal–ceramic bond strength. Materials and Methods Six CoCr‐based alloys were included in this study, a were classified into three different groups ...

Program for an improved hypersonic temperature-sensing probe [PDF]
Under a NASA Dryden-sponsored contract in the mid 1960s, temperatures of up to 2200 C were successfully measured using a fluid oscillator. The current program, although limited in scope, explores the problem areas which must be solved if this technique ...

New Zealand Journal of Geology and Geophysics, Volume 69, Issue 2, June 2026.Clasts of albite‐porphyroblastic quartzofeldspathic schist, derived from the Otago Schist basement, occur within the Port Chalmers Breccia, a diatreme at the centre of the Dunedin stratovolcano, New Zealand. Schists have undergone varying degrees of replacement reactions (at temperatures of 300° to >500°C) producing hornfelses, with Ca‐ and K‐enriched ...
